المستخلص: تشمل هذه الدراسة طريقتين مهمتين في التطبيق التحليلي لتعيين وفصل واغناء ايون النحاس الثنائي بطريقة نقطة الغيمة والطريقة الطيفية وذلك باستخدام مطياف الاشعة الفوق البنفسجية - المرئية. في الجزء الاول : تم استخدام الحامض الاميني الميثونين ككاشف تحليلي الذي يشكل مركب مخلبي مع ايون النحاس في الطور المائي وبدرجة حموضة محددة, والذي تكون له اعظم امتصاصية عند طول موجي (244 نانوميتر) لمعقد النحاس - الميثونين ضد الميثونين كبلانك.وتم دراسة الظروف الفضلى للتفاعل بالاضافة الى العوامل التحليلية الاخرى وافضل نتائج تم الحصول عليها لمنحني المعايرة والبيانات الاحصائية تحت الظروف الفضلى التي تم الحصول عليها بالطريقة الطيفية المباشرة لكميات صغيرة من النحاس, يطاوع قانون لامبرت بير في مدى تراكيز (0,1 - 10) ميكروغرام/مل مع امتصاصية مولارية (5842 لتر.مول - 1.سم - 1) وحد الكشف (0,0238 ميكروغرام/مل) في هذه الدراسة لوحظ حدوث تداخلات بعض المعادن مثل النيكل (II)والكروم(III) في ايون النحاس وقد تجاوزت الحد المسموح للتداخل , لذلك تم تطبيق الطريقة المقترحة بنجاح لتحديد ايون النحاس في عينات مختلفة من المياه.اما الجزء الثاني من الدراسة تستند على تكوين معقد كاره للماء بين ايون النحاس والميثونين الغنية بالترايتون 100 - X من خلال منهجية الاستخلاص بنقطة الغيمة الى جانب القياس الطيفي للاشعة فوق البنفسجية - المرئية, في هذه الطريقة يتشارك ايون الفلز مع الحامض الاميني الميثونين في تفاعل لتشكيل معقد مخلبي كاره للماء ويتم استخلاص هذا المعقد في درجة حموضة معينة عن طريق الاستخلاص بنقطة الغيمة باستخدام المركب السطحي غير الايوني ترايتون 100 - X كوسيط للاستخلاص.الطور العضوي الغني بالمادة السطحية يتم اذابتها باضافة الميثانول ويتم قياس المعقد طيفيا عند طول موجي (294 نانوميتر) لتحسين العوامل التي تؤثر على كفاءة استخلاص ايون النحاس باستخدام احد عوامل التحليلية وتشمل هذه العوامل درجة حموضة المحلول تركيز الليكند والمادة السطحية, درجة الحرارة والوقت التي تم تحديدها بالاضافة الى الكتيونات التي تعتبر متداخلات في ظل الظروف المثلى للتفاعل وقد تحقق عامل اغناء النحاس وكان منحني المعايرة الخطي (0,1 - 4) ميكروغرام/مل, حد الكشف والحد الكمي (0,0071) (0,0215) على التوالي. وتم مقارنة الطريقة المقترحة مع الطريقة الطيفية المباشرة لتعيين ايون النحاس ومن خلال النتائج المعروضة نلاحظ اختلافات كبيرة في الدقة والتوافق في الطريقتين وان الاستخلاص بنقطة الغيمة هي الاكثر دقة وتوافقية. تم تطبيق هذه الطريقة في عينات المياه. في هذه الدراسة تم تعيين تكافؤية المعقد عن طريق النسب المولية, التغيرات المستمرة (طريقة جوب) في درجة حموضة معينة واظهرت النتائج ان نسبة التكافؤ بين ايون النحاس الميثيونين هي 1 : 2. | This study in whole comprises two significant approaches in analytical application for direct determination and separation with preconcentration of copper ion by cloud point extraction methodology coupled with UV - Visible spectrophotometry.In the first part : The amino acid methionine was used as a chelating agent to form a complex with copper ion in aqueous phase at specific pH, which exhibits maximum absorption at (max= 244nm) against reagent blank. The optimum reaction conditions and other analytical parameters were evaluated. The results showed better optical characteristics for calibration curve and statistical data were obtained under optimum conditions using direct Spectrophotometric determination of micro amounts of copper ion. “Beer's law” is obeyed in the concentration range (0.1 - 10)g.mL - 1 , having molar absorptivity of 5842L. mol - 1. cm - 1. The value of detection limit was 0.0238g.mL - 1 . Interference study indicated that some metal ions like Ni+2, Cr+3 have exceeded the allowable limits of interference for copper ion absorbance signal. The proposed method was applied successfully for the determination of copper ion in various water samples.Part Two : Deals with the formation of a hydrophobic complex between copper ion and methionine in rich - surfactant phase, by “cloud point extraction” (CPE) methodology, coupled with UV - Visible spectrophotometry. This method involved reaction of copper ion with methionine as a chelating agent to form a hydrophobic complex. Which was extracted at specific pH by CPE technique using nonionic surfactant Triton X - 100.as an extraction medium. The complex was surrounded by surfactant micelles. The surfactant - rich phase was diluted with methanol and the complex was measured spectrophotometrically at it's (max= 294nm). Different factors that can influence the extraction efficiency of copper ion has been optimized by using one - factor - at - a - time (OFAT). These factors include solution pH, reagent and surfactant concentrations, temperature and incubation time. Besides the interference effect of cations was also considered under the optimized conditions, “preconcentration factor” of 90 was achieved. The linear range was (0.1 - 4)g.mL - 1 with “limit of detection” and limit of quantification (0.0071), (0.0215)g.mL - 1 respectively and molar absorptivity of (19621.5) L. mol - 1. cm - 1.The Stoichiometric study was determined by “mole ratio method and continuous variation method” (Job's) at specific pH. The results showed that the Stoichiometric ratio between copper ion and methionine was 1 : 2.The proposed method is compared with the direct spectrophotometry determination of copper ion and the results have shown that there is a significant differences in accuracy and precision between the two methods and the cloud point extraction which indicates that the latter is more accurate and more precise. The suggested method was applied successfully for the determination of copper ion in water samples

المستخلص: هدف البحث الحالي الى : - تحليل محتوى كتب الكيمياء للمرحلة المتوسطة على وفق قضايا العلم والتكنولوجيا والمجتمع والبيئة ( S.T.S.E ). ولتحقيق هدف البحث صيغ السؤالان الاتيان : - 1 - ما قضايا العلم والتكنولوجيا والمجتمع والبيئة ( S.T.S.E ) المتضمنة في محتوى كتب ا | The aim of the present research is to : Analysis of chemistry books for the intermediate stage and according to science and technology, society and environment issues ( S.T.S.E ). To achieve the aim of the research the following two questions formats : - 1 - What are the Science and technology, society and enviermental issues (S.T.S.E) which included in the content of the chemistry books for the preparatory stage?2 - What are the Science and technology, society and enviermental issues (S.T.S.E) which supposed to be included in the content of the chemistry books for the preparatory stage?And to answer the research questions : Related to the first question : - The researcher has depended on previous studies in the field of (S.T.S.E), movement and projects that has contributed to reform of the science curriculum in order to prepare a list of science and technology, society and enviermental issues (S.T.S.E) , the first draft of the issues list consisting of (9) main issues and (69)sub - issues emerged. The researcher distributed the first draft of the list among experts in teaching chemistry, curricula and teaching methods, teachers and supervisors who were expert in the area of teaching chemistry methodsthen the researcher gave them enough time to check each item and removing or adding what is suitable for the tool to become in its final draft which included (9) main issues they are (Air quality and the atmosphere, sustainable development, water security, health and preventive security, mineral resources investment, pollution of various kinds, energy, food industry, production of weapons technology) and from which (70) sub - issues emerge. Then, the researcher analyzed the content of the chemistry books for the preparatory stage in the academic year (2015 - 2016) depending on the prepared list of the (S.T.S.E), the researcher depended the unit analysis, both (implicit and explicit) and repetition unit of the Census, the stability of the analysis was counted with the agreement of an outlaws analysts and the researcher himself.The researcher used Holisti equation for calculating reliability coefficients values, the results showed by using frequencies and percentages : - 1 - The chemistry books for the preparatory stage achieved ( 35) sub - issues with percentage of (50 % ), and this percentage is not good if we compare it with the criterion percentage that was adopted by the researcher depending on the experts opinions which was ,(70%).2 - Principles of Chemistry book for the first level preparatory class is the most book that gave an attention to the (S.T.S.E) issues with percentage of (65%), and (156) recurrence, but the second preparatory class was the least book that gave an attention to the (S.T.S.E) issues with percentage of (14,17%), and (34) recurrence.3 - health and preventive security issues settled at the first place with percentage of (27,08%), and (65) recurrence in the chemistry books for the preparatory stage, While the production of weapons technology issues settled on the last place and did not get any recurrence. 4 - The - sub - issue (the role of the chemical elements in nature) had the biggest number of recurrence which was (31), and settled at the first place, while many sub - issues did not get any repetitions.Respecting the second question : - The researcher found that most of the sub - issues were not included in the content of the chemistry books for the preparatory stage , which was included by the researcher within the issues list (S.T.S.E), The researcher finds that it is possible that the chemistry books for the preparatory stage should include the (S.T.S.E) issues in its content , Being a contemporary and important manner commensurate with the size of these issues, taking into account integration and relay and balance specially the main issues (mineral resources investment, food industry, production of weapons technology ) , which the current study had talked about it the knowledge of the researcher. Even though, the first issues took the third place, and the second issues was in the fourth place, but the third issue did not get any recurrence, which means the absence of balance and integration, related to the content of the chemistry books for the preparatory stage.In the light of the findings, the researcher came out with several recommendations, they are : - 1 - Including chemistry books for the preparatory stage with main and sub - main issues of the (S.T.S.E) issues that have not been included. 2 - Drawing the attention of specialists to reform science curriculum especially chemistry curricula, as one of the important modern attitudes in the scientific education.3 - Involving people who are interested in environmental education and specialists in the field of environment within special committees for plan science curriculum and specially chemistry curriculum. Complementing the current search the researcher suggested to conducting other studies to analyze chemistry books for the other stages, and other subjects such as physics in the light of the same issues.

The researcher believes that.this classification is very important for the following reasons : 1 - This is the first study in Iraq for the analysis of questions for the.Biology book of the seconday stagedue to the importance of this stage, which is a passport to universities and scientific life. 2 The search results can be used when a revision or re - writing books, especially the questionsat the end of chapters to introduce four levels of classification in future editions. 3 - To emphasize the importance of the questions and their effective role in the educational process, which is the cornerstone to understanding the scientific material between the covers of the book. 4 - Confirmation researcher on the comprehensiveness and credibility and objectivity of the questions through the results obtained to be taking in the future. The research frame Questions from the ends of chapters for biology books of the three levels in the Secondary stage. The research sample The research sample included three biology books of the preparatory stage. the number of key and subset questions is (615) distributed as follows : It was 161 key questions distributed as follows : 70 questions for the fourth year which new respnt 43% of the total number25 questions for the fifth scientificyearwhich is 16% and for the sixthscientific yearther are 66 questions which is 41%, while the total key questions, along with its subsidiaries were 615 questions distributed as follows : Fourth Scientific 141 question (23 %) as well as the for the fifth year the questions number is 140with percentage 23% finelly. for the sixth scientificyear the number of the questions is (334) with percent age(54%). Research tool The questions at the ends of the chapters wereclassified according to the four levels of Gallagher and Aschner classifcation (cognitive thinking, convergent thinking, divergent thinking, Evaluation thinking) The questions were classified according to the following : 1 - Determine the relative weight of the content areas of the three books in recent editions, which studied by the students for the academic year 2013 - 2014. 2 - determine the relative weight for Gallagher and Aschnerclassification. 3 - Extraction of objectivity and essay questions for each chapter of the book. 4 - Find the inclusion of questions of the goals and course material and content. 5 - Find the truth range of the content by comparing expected specifications table with theobserved specifications table. Research Results The researcher rcaches to the following results : 1 The average relative weights of the cognitive levels of Gallagher and Aschner classification for the biology books of for the preparatory level of thinking cognitive is (80%) and for the convergent thinking (19.18%), while the divergent thinking has reached (0.81%), we did not find any replicate of the level of eveluating thinking. This suggests that the High levels of thinking was not demoustvted in those books and that makes students where not familier on these types of questions. 2 - The repetition of objectivity questions was (330) paragraph (53.65%) while the repetition of essay questions was (285) paragraph (34.46%).The book that in to account the objectivity standard was takes book of the fifth grade.And then book of the sixth grade and finally the book of the fourth grade. 3 - The inclusion in the books for the Scientific Fourth and Fifth Grades has been very weak compared to the proportion of inclusiveness adopted the coverage proportion for the sixth yeam book was 84.3% The rate of the proportion of inclusiveness for all the three books was 87.68% 4 - The value of the coefficient of truthful content was very weak (0.446) when compared to what the experts think of the weights for each of the cognihve field of obsened specifications table. Recommendations In light of the research results.we necommendthe following recommendations : 1 An attention is needed for different levels of when preparing textbooks questions for the purpose of improvement and development. 2 The book questions should not be focus on the essay questions, as should include objective questions (multiple choice, matching fictures and the assertion and reason and others). 3 - The questions book should cover chapter headings in the textbooks. 4 - drafting additional questions at the end of each book of the three books take into account the standards of good questions according to the higher levels of thinking. 5 - need to adopt a specification table when preparing the questions and evaluate constantly. Proposals In light of this, the researcher suggested a number of proposals, including : 1 - conducting similar studies for the final and school exam questions for biology subject according to Gallagher and Aschner classification. 2 - conducting similar studies to the ends of chapters questions fro chemistry and physics for the secondery level. 3 - Conduct studies to show the difficulties that hinder the application of the upper levels of the evaluation like divergent thinking andevalute thinking for the exams in biology at the various stages of study

المستخلص: يعد القسم العلمي الوحدة الاساسية للجامعة ومعظم القرارات تتخذ من خلاله فضلا عن كونه الجهة المناط بها تنفيذ القرارات الصادرة من الجامعة، وموقع رؤساء الاقسام يمثل مفتاح نجاح تلك الاقسام وانطلاقها نحو تحقيق اهدافها، اذ ان كفاءة اداء القسم العلمي تتاثر كثيرا ب | The "scientific section the basic unit of the University of Most decisions are made through the site department heads represents the success of those sections and disperse the key towards achieving their goals, and that the strength and success of the sections in the performance of its duties the success of the university and continuity in survival shows" (Harab : 1998.51). However, some of the operating and administrative functional centers do not have to have administrative or even the willingness of mental and psychological ability to understand non - specialists and do not have the necessary competence, so the development of policies that are trying to eliminate this phenomenon and the resulting disadvantages. "Forums heads are academics before everything, not administrators, but they exercise the functions of the presidency of the section without having the necessary expertise and without access to any kind of pre - training and this means ambiguity of roles they have absence of advance preparation for the Head of Department to exercise its role creates a problem in itself." (Munir : 1999.56 - 57). "The nature of interlocking and complex role of Chairman of the Scientific Section and its administrative and academic tasks, especially in the absence of job descriptions and training programs to prepare who will take the job, may give rise to perceptions of non - specific about the powers and duties assigned to, which could be hampered by the performance of some of its functions and implement some of the duties entrusted to him, and so in the belief that they fall outside the framework of the powers and duties assigned to the President of the section "(age : 1998.256). So hold many conferences that shows the importance of developing the performance of educational leaders, as in the first Scientific Conference of the Colleges of Education and Human Sciences at the University of Anbar in 2011, and highlighted what is in it that there is weakness in the level of administrative performance of most of the educational leaders in Iraqi universities and the need to improve the performance of those leaders. (First Scientific Conference of Colleges of Education : University of Anbar 0.2011). Fifth Scientific Conference and discussed at the University of Maysan, 2012, which was held under the slogan (the role of universities in the construction and promotion) discussed the development of educational systems departments and it is different from other community systems departments because the entrance to the heterogeneous and difficult to adjust and control due to the different intellectual, cultural and social levels, which requires the presence of administrative leadership effective. (Fifth Scientific Conference : Maysan University, 2012). In addition to the above has the researcher conducted a number of meetings and interviews with a number of administrative leaders in Wasit University and their assistants and heads of academic departments, and through discussions it became clear that there are problems hindering the administrative performance of the development of the Heads of Departments, including the discrepancy in the decisions and instructions of the higher authorities, a what does not help to take the right decisions, poor rehabilitation of educational leadership and not giving in to the criteria for selecting the leadership, weak employment of modern information and communication technology in administrative work, the lack of secretarial effective offices in the scientific section, lack of equal validity with placed on the head of the department responsible. Based on what was presented conferences and problems and weaknesses, and studies of the recommendations made, as well as the interview conducted by researcher The problem with current research in the administrative performance development, and as the administrative work does not evolve, but the evolution of the existing performance of the exercise, change roles so is a set of ideas and routers work and the introduction of updates and make changes designed to improve the performance of heads of academic departments at the University of Wasit mode. And which will reflect positively on the administrative functioning of the first academic work and secondly in teaching, scientific research and community service. The importance of this study is being dealt with very topic in importance, namely the administrative performance development of the heads of academic departments at the University of Wasit in light of the administrative functions based on the areas of (planning, organization, guidance, administrative communication, monitoring and evaluation). Thus is the positioning of the new study and research topics from the university's success is linked to the successful divisions, and effective leadership for scientific department is always seeking to improve its performance in accordance with contemporary management trends.

The researcher depends on the experimental design of two equivalent groups that have dimensional test. According to this design, a sample has been chosen - the sample consists of female students of the fourth primary class from (Um Al - Baneen) Primary School for Girls in Baghdad belongs to the Second Karkh Educational Directorate, for the academic year (2015 - 2016) [First Semester]. The sample consists of (98) female students divided equally into two classes, one of them resembles the experimental group, and the second resembles the controlling one. The researcher has chosen section (B) randomly for teaching the scientific concepts by using Deenz’s strategy, and section (A) has been taught the scientific concepts by using the traditional approach. The two groups have been equivalent concerning certain variables : age, scientific achievement in (Science) for the third primary class, the scores of previous achievement test, the scores of intelligence test, the parent’s achievement. The behavioral objectives have been designed as three levels for processes of acquiring the concepts; they are : definition, distinction, and application. The behavioral objectives are (45) and they have been used in writing the lesson plans for teaching relying on the independent variable. The researcher has prepared a test for acquiring the scientific concepts for it is the ‘tool’ of the research. The items of the test are (45) in the light of processes of acquiring the three concepts : definition, distinction, and application. The validity of the test has been checked, and even its reliability and the power to discriminate, the difficult level of its items, and the effectiveness of its variables have been checked. After ending the research experiment, the test of acquiring the scientific concepts has been applied for the female students of both (experimental and controlling) groups. Moreover, a statistical treatment for the data has been implemented by using the (t - test) for two independent samples. Consequently, the results have shown the excellence of the experimental group - which has been taught the scientific concepts by using Deenz’s Strategy - on the controlling group which has been taught the same concepts but by using the traditional approach. In the light of the results of this study, a number of concluding remarks have been got concerning the results and the related recommendations, and some suggestions have been set for future researches in this aspect.The Title : The Impact of Deenz’s Strategy in Acquiring the Scientific Concepts by the Female Students of the Fourth Primary Class in (Science)

In the same sense, the educational management has become the core interest of the researchers ,thinkers, educational leaders and educationalists as a whole for it is considered one of the supreme jobs that is mainly concerned with the individuals' growth , their intellectual and cultural evolution ;therefore giving the role it is deserved has become of high importance. For the educational organizations to be felicitous and effective, there must be efficient and administrative leaders who are able to fulfill their duties and tasks effectively as well as the availability of the convenient systematic circumstances for the sake of the proper execution of the managerial works.Furthermore ,those leaders have to possess skills of leadership associated with the processes of creativity ,innovation , renovation ,and the ability to solve and face problems. Hence, the administrative behavior conducted by the head of the scientific department is regarded as a pillar within the entire educational leadership, for the success of such a process is highly dependent on the type of the behavior conducted which in turn will affect those behaviors conducted by other instructors in creating the scientific climate prevailed which is a continuity of the scientific achievement and the educational procession as a whole.Moreover, the head of the scientific department is considered one of the important administrative leadership at the college forming a significant part of its structural and systematic components ,that is he/she possesses the pioneering role within the educational and administrative process ,being a link between the department's instructors and the deanship of the college.This is due to the fact that there is consensus among the majority of the researchers that the administrative behaviour of the head of the scientific department in its various patterns highly effects in constituting the occupational satisfaction of the instructors and personnel which in turn will reflect on the quality and efficiency the performance.This clearly shows the effectual impact of the administrativ behaviour between the administrative leaderships represented by the heads of departments and the instructors working with him/her in shaping their satisfaction and assurance which will identify their own motivation to achieve the general goal of the scientific department. Certainly, there should be certain factors that affect the satisfaction level of college instructors, the first of which is the administrative behaviour conducted by the heads of the scientific departments through their daily ways of dealing ,communicating , and along with the administrative practices to the degree that the interest on the occupational satisfaction of the instructors and everything that would increase their spirits has become one of the modern trends at the educational organizations.This is what the present study will tackle circling around the fact that there are problems related to the nature of the administrative behviour belong to the heads of the scientific departments and the consent of the occupational satisfaction of the teaching staff members. This subject, as the researcher believes ,is one of the important phenomena that is in the core of the work and sustainability of the scientific departments for the sake of increasing the scientific outcome of such departments which in turn will facilitate the processes of development and change of those behaviours conducted by the heads of the scientific departments and creating a quantum shift to achieve the general goals of the scientific departments.The significance of the current study can be clarified in the following points : 1 - The administrative behaviour is considered the vital factor the highly affects the individuals' behaviours of the teaching staff members and other personnel.2 - Showing the role acted by the head of the scientific department as an advanced cultural mark in the society who performs a role that highly affects the teaching staff members through finding out those factors related to the occupational satisfaction.3 - Finding out those aspects of satisfaction and non satisfaction of the teaching staff members at the university of Baghdad in order to reinforce the aspects of satisfaction and treat those aspects of the non satisfaction.4 - University of Baghdad may make use of the recommendations set in this study to develop the administrative behaviour of the heads of the scientific departments at the colleges of the university of Baghdad to suit the occupational satisfaction of the teaching staff members. The present study aims at finding out : 1 - the level of the administrative behaviour of the heads of the scientific departments at the colleges of the university of Baghdad.2 - the level of the occupational satisfaction of the teaching staff members of the scientific departments at the colleges of the university of Baghdad.3 - the relationship between the administrative behaviour of the heads of the scientific departments and occupational satisfaction of the teaching staff members.4 - if there are any statistically significant differences in the level of the managerial behaviour of the heads of the scientific departments at level of significance of (0.05) according to the variables of : - College Specialty ( Human - Scientific ). - Gender ( Males - Females ).5 - if there are any statistically significant differences in the level of the occupational satisfaction of the teaching staff members at level of significance of (0.05) according to the variables of : - College Specialty ( Human - Scientific ). - Gender ( Males - Females ). The population of the present study covers all the teaching staff members at the colleges of the university of Baghdad( Human - Scientific )for the academic year 2014 - 2015.The total number of the population is (6210) of males and females instructors at the colleges of the university of Baghdad from which the researcher has selected (310) subjects which forms (5%) out of the original population. Two instruments have been constructed, one of them is related with the administrative behaviour and the other with the occupational satisfaction. The psychometric features of the instruments have been verified. In order to achieve the aims of the current study ,the researcherhas utilized the descriptive analytic approach as well as the proper statistical means (SPSS).Then, the researcher has come up with certain results : 1 - Heads of the scientific departments possess a good level of the administrative behaviour.2 - Teaching staff members at the colleges of Baghdad possess a degree of the occupational satisfaction.3 - There is a correlational relationship between the administrative behaviour and occupational satisfaction.Based on the results obtained ,specific conclusions have been set : 1 - The administrative behaviour has a vital and affected role on the instructors' satisfaction and their performance at the scientific departments which indicates the need for good dealings and humanitarian relationships among members at these departments. 2 - The administrative behaviour and the occupational satisfaction is considered a formula between two parts affected each other ,in that whenever there is an increase of the good occupational satisfaction ,there is also an increase in the administrative behaviour and vice versa.According to the conclusions gained ,certain recommendations have been set as follows : 1 - Studying the results extracted from this study by both the heads of the scientific departments and instructors at different universities to make use of such results in treating the problems faced and in proceeding the managerial affairs.2 - Adopting the above results in workshops or training courses held within the academic year and for all levels (administrative - instructional - supreme leaderships)at the university of Baghdad.3 - The supreme administration the university of Baghdad is recommended to consider the education degree and the scientific rank into consideration when assigning the heads of the scientific departments and to select those who are Assistant Professors and hold the Ph.D. to properly achieve the university's goals and grant the real status deserved by the heads of departments.Finally, some suggestions are put forward as follows : 1 - Conducting a study to find out the relationship between the administrative behaviour conducted by the heads of the scientific departments and systematic commitment revealed by the teaching staff members at the colleges of the University of Baghdad.2 - Conducting a study to find out the difficulties faced by the heads of the scientific departments at the colleges of the University of Baghdad or other Iraqi universities.3 - Conducting a study to find out the administrative behaviour conducted by the deans of colleges and its relationship with the occupational satisfaction of the heads of the scientific departments

The researcher used as a population and sample of her research two of the computer textbooks content that has been decided for the intermediate stage students, they were (the first and second intermediate level textbooks).In order to prepare the first draft of the research tool that content the five technological literacy fields (The Nature of Technology, Technology and Society, Design, Abilities of Technological World, The Designed World) the researcher depended on the international Standards for Technological Literacy : content for the study of technology (STL) which was approved by the International Society for Educational Technology after translating and adapting them according to the Iraqi environment.In addition to an exploratory study on a sample of (20) computer teachers distributed between first Rusafa and second Rusafa by directing an open ended questionnaire included questions to suggest what are the suitable criteria and indicators for each of the technical literacy fields that should be included in the list.The researcher distributed the first draft tool among some experts and gave them enough time to check each item and removing or adding what is suitable for the tool to become in its final draft in order to measure what has been prepared to measure, then the computer textbooks content was analyzed and evaluated according on its light.The researcher prepared a criterion to represent the percentage of these fields related to the academic content based on the viewpoints of specialists in educational and scientific area.Regarding the unit of analysis it has been adopted the unit idea (explicit and implicit) as a unit of analysis, in order to validate the veracity of the analysis after displaying a model of the analysis method on a number of specialists who have experiences in content analysis, as well as confirming the stability analysis by an agreement with the researcher herself and with two of outside analysts ,the reliability was ranging between (87.33% - 96.09%), the acceptable stability of transactions. The researcher used a number of statistical methods such as (percentages, J. Cooper equation to calculate the stability of the content analysis, Chi - square to compare the percentages of the results of the analysis with the proposed arbitrators' specialists' percentages and (SPSS).It has been found that the content of intermediate Computer Textbooks phase did not take into account the technological literacy fields required level axes were not observed, but the interest came about is an irregular and balanced, as well as the omission of Textbooks to a set of criteria and indicators pertaining to technical literacy axes, so the researcher prepared a suggested material include these criteria and indicators after presenting them to a group of specialists in the fields of computers, curricula and methods of teaching science.In light of the results of this research some conclusions have been reached the most important of them are weakness of specialists familiarity and respective personnel to prepare the content of computer Textbooks for the intermediate level by international standards relating to the technical literacy fields, and that the process of distribution of standards among Computer Textbooks content for intermediate stage has wildly irregular.Therefore, based on the findings some recommendations are suggested.The most important of them are guiding and drawing attention of specialists who are in charge of the preparation and development of the computers curricula material in the Ministry of Education to benefit from the suggested material that the researcher has developed in this research by including computers textbooks content the standards of the technical literacy fields that are unavailable in the current textbooks and to keep up with the current developments, moreover, taking into account integral and sequence and balance of Computer textbooks by including the standards of technical literacy fields and indicators.To Complementing and development this research the researcher put some suggestions, including : 1. Conducting a similar research for the preparatory stage to evaluate the computer textbooks according to technical literacy, so specialists and concerned people who are involved in the preparation of the computer textbooks content have complete information.2. Conducting a comparative study between the computer textbooks content in Iraq in a specific school stage, and other countries textbooks according to the technical literacy standards.

For evidence the objective of the research, the researcher formulated the following two null hypotheses : 1. There is no significant difference at the statistical level (0.05) between the average of scores of the experimental group students they are studied according to the dualism strategy of analysis and structure and the average of scores of the controlled group students they are studied according to the normal way in the achievement.2. There is no significant difference at the statistical level (0.05) between the average of scores of the experimental group students they are studied according to the dualism strategy of analysis and structure and the average of scores of the controlled group students they are studied according to the normal way to test high - order thinking.To achieve the aim of research, the researcher used experimental design a partial control, as well as a current research was Identified by choosing scientific fourth stage students in the governmental diurnal secondary schools which obey to Baghdad education directorate / the first Karkh of studious year (2014 - 2015). The researcher selected purposively Ajnadayn secondary of girls as a research sample, and was selected two divisions of the scientific fourth stage randomly, one of them represent the experimental group and another the controlled group. The sum of research sample was (69) students, (34) students of them in the experimental group and (35) students in the controlled group.The two groups of search were tested by four variables (the time age, scores of biology material in the test of end of the first course, the scores of test of previous biology information, and the test of intelligence), also the scientific material was defined with the last five chapters of the Book of Biology which is scheduled to teach of studious year (2014 - 2015). The behavioral objectives were formulated of these chapters and numbered (256) behavioral objective represented to six levels of Bloom's Taxonomy in the knowledge field (remember, absorbing, application, analysis, structure, and evaluation). The tutorial plans were prepared for the two groups of research and numbered (22) plans for each group. The researcher taught herself the two groups during the period of the experiment, which continued (10) weeks of the second semester of the academic year (2014 - 2015).With respect to the research tools, the researcher used one tool for each dependent variable, as prepared achievement test of last five chapters of the book of Biology of the scientific fourth stage consisted of (47) items represented the substantive questions, as well as the researcher adopted test of study in high - order thinking consisting of (30) items represented in the two types of questions : (15) objective paragraphs, and (15) essay paragraphs, were checking the veracity of tools through articles on a group of arbitrators, have been applied to investigational samples one of them to see how clear paragraphs and time of answer and the other was for the purpose of test statistically analyzed by extracting The psychometric characteristics, in addition to the extraction of the stability for both tests.After the end of the experiment, the two tools were applied on groups of search, then the students, answers were corrected and they were treated statistically. The results were as the following : 1. There are statistically significant differences in favor of the experimental group in the achievement test with the large effect size of the independent variable were (0.82).2. There are statistically significant differences in favor of the experimental group in the high - order thinking test with the middling effect size of the independent variable were (0.70).The results indicated that there is a positive effect of teaching by strategy of binary analysis and synthesis strategy on the achievement and the high - order thinking, in the light of that the researcher put a number of recommendations and suggestions

المستخلص: The current research aims to verify the impact of the Stepanz model to modify wrong understanding of the physical concepts when students fourth grade science and their social intelligence. The researcher formulated the two following zero hypotheses for purpose of verification of the aim of the research : 1 - There is a not statistically difference is significant at the level of significance (.0.5) between the average scores of the experimental group students who are studying using the Stepanz model and between the average scores of the control group students who are studying in the usual way in the diagnosis test of the wrong understanding of the physical concepts. 2 - There is a not statistically difference is significant at the level of significance (.0.5) between the average scores of the experimental group students who are studying using the Stepanz model and between the average scores of the control group students who are studying in the usual way in social intelligence scale. The researcher chose a sample for his consideration students of grade forth Scientific in junior high Alfaruq of The first breeding Karkh Directorate, has identified the pilot divisions and control group randomly by lot, as the number of students reached in divisions (55) student after excluding students Alraspat and by (22) student to experimental and (22) student of the officer, and for determining the content of scientific material has identified chapters VI, VII, VIII, IX and X of the fourth book of physics and scientific - grade second semester. equivalence were conducted for the following two variables (age students in months and the degree of the previous achievement in physics and the degree of the previous achievement in mathematics and the previous test information and test misconception and scale social) intelligence. The researcher used two tools to achieve the purposes of research and two (test misconception) and be one of the (51) paragraph in its final form and scale of social intelligence and be one of the (4.) as the final paragraph. Researcher following statistical methods were used to arrive at the results of his research (samples t - test for two independent samples is equal, and the coefficient of difficulty,and the coefficient of discrimination paragraphs and the equation of the effectiveness of the wrong alternatives to paragraphs test misconception, and Pearson correlation coefficient, and the equation Spearman - Brown, Alpha Cronbach the equation, and the equation of effect size). The search procedure has two phases : 1. The first phase of the diagnostic : it applied the researcher tested the wrong understanding of the concepts was a number of misconceptions (12) concept of experimental and (11) a concept of an officer of the asset (12) is selected concept exceeded error where the proportion (343) are distributed between Chapters VI, VII, VIII, IX and the tenth book of Physics fourth grade science. 2. The second phase of treatment : the applied research procedures on the two groups, the researcher has studied by Stepanz model the experimental group, while the control group studied the usual way. The researcher reached to the following results : 1. there is a statistically significant difference between the experimental and control groups for students in the fourth grade scientific diagnostic test for the wrong understanding of the concepts physical and in favor of the experimental group. 2. there is a statistically significant difference between the experimental and control groups for students in the fourth grade scientific measure of social intelligence and in favor of the experimental group. Accordingly the researcher reached to following conclusions according to the results of research : 1. The use and application of a Stepanz model in teaching physics fourth grade science have an impact in the amendment misconception which is owned by students in physics. 2. The use and application of the Stepanz model in physics teaching fourth grade science have an impact in raising and improving the degree of social intelligence of students. Accordingly, the researcher has developed a number of recommendations and suggestions for the use of Stepanz model in other studies in other stages and in other scientific materials and a sample of other research.
