Abstract: يعد الاستيعاب القرائي واحدا من المهارات المهمة الواجب تطويرها لما له من وثيق الصلة بتطور القدرة اللغوية لدى متعلمي اللغة الاجنبية في حياتهم المستقبلية فباكتسابهم عادات القراءة الصحيحة يستطيع هؤلاء المتعلمون ان يحققوا نجاحا في كافة المواد المطلوب منهم قر | Reading comprehension occupies an important position in the language teaching programme because of its relevance to foreign language learners in their future life, i.e., if they acquire the habits of good reading, they will be able to make good progress in almost every subject they have the opportunity to study. Due to the educational findings which clearly show that there are some weaknesses in the reading comprehension ability of foreign language learners throughout all the academic stages(including the intermediate stage). English foreign language teachers in Iraq complain of their students' low ability in reading comprehension, especially in answering higher level questions. To overcome this problem, the 'using Questioning Techniques' are suggested to activate learners' both lower and higher levels of cognitive skills and urge them to use their background knowledge to interact with the text, and to enable teachers to involve their students in a complemented interactive process in the classroom. Hence, the present study aims at empirically investigating using questioning techniques (using the lower level of questions) on EFL second intermediate school' achievement in reading comprehension. To achieve the aim of the study, it is hypothesized that there is no statistically significant difference between the scores of the experimental group who is taught according to Bloom's levels of questioning and the control group who is taught according to the classical teaching method. To verify this hypothesis, a pre - posttest experiment has been designed. Eighty - one second - grade Intermediate male students are assigned to the experimental and control groups, 40 students are for the experimental group and 41students also are for the control group. Both groups are statistically equalized in a number of variables such as age, parents' level of education, student's intelligence level, students' scores in English in the previous year, and students' scores obtained on the pretest. The experimental group has been reading comprehension by using Bloom's levels of questioning whereas the control group is taught by the Classical Teaching Method (i.e., currently - followed method),.The method has been recommended in the teacher's guide for Book 6. The experiment is conducted in Zain Al - Abideen Intermediate School for Boys, and lasted for two months in the academic year 2012 - 2013.After administering the posttest, the results obtained show indicate clearly that the achievement of the experimental group who were taught by using Bloom's levels of questioning has been higher than that of the control group who was taught by the classical teaching method. In other words, Bloom's levels of questioning is more effective than the classical method. Due to the results obtained from this study, a number of conclusions has been come up with, among which the most important ones are : 1. Teaching literary section according to Bloom's levels of questions in RC gives the students the opportunity to comprehend so many vocabularies and to increase their vocabularies store. This leads to generate many ideas concerning one subject, and widen their imagination.2. Bloom's levels of questioning have proven to be an effective and useful ones for using questioning techniques because they enable the teacher to guide and evaluate the students’ progress from one level to another in a gradual manner. 3. Literature helps students to be well - quainter with the English culture which in turn expands their skills, culture knowledge.Also, Recommendations and suggestions for further studies have been put forward.

Abstract: Critical thinking is an important everyday activity. Every time we have to make a decision, the process we go through involves critical thinking. Nowadays, critical thinking is one of the major concepts under consideration in education.Reading has also been considered one of the most important skills in EFL/ESL context. Hence, the integration of critical thinking and reading could be most effective to learners. To develop students' critical reading ability is a major goal in reading instruction.Considering the substantial roles of EFL/ESL reading comprehension and critical thinking skills, it can be noted that these two variables are required for students to succeed in academic English settings.In line with the studies confirming the positive relationship between critical thinking ability and language proficiency, this study intendes to investigate the relationship between the EFL college students' critical thinking and their performance in reading comprehension. Hence, the present study aims at : 1 - measuring EFL college students' critical thinking skills;2 - measuring EFL college students' reading comprehension performance;3 - finding out the relationship between students' critical thinking skills on one hand and their performance in reading comprehension on the other; and4 - investigating whether gender makes difference in the relationship between critical thinking and reading comprehension.To achieve the aims of the study, four null hypotheses have been stated as follows : 1 - Third - year EFL college students' level on the critical thinking test is average.2 - Third - year EFL college students' performance on the reading comprehension test is average.3 - There is no statistically significant relationship between Iraqi EFL students' critical thinking and reading comprehension performance.4 - There is no statistically significant difference in the relationship between Iraqi EFL students' critical thinking and reading comprehension performance according to the gender variable. A random sample of third - year college students enrolled for the academic year (2013 - 2014) has been selected. The number of participants is 62 representing 30 % of the total population.In order to fulfil the aims of the study and to test its hypotheses, two instruments have been adopted for data gathering; Watson - Glaser Critical Thinking Appraisal (WGCTA) Test and astandardized Reading Comprehension Test. The instruments are exposed to a jury of experts for the purpose of ascertaining their face and content validity. They have validated the items and suggested some modifications. After a pilot administration of the instruments, their reliability is calculated by the split - half method for the (WGCTA) Test, and the mark - remark method for the reading comprehension test, yielding reliability coefficients of 0.72 and 0.81 respectively. The discriminatory powers and difficulty level of the instruments' items are also computed.After the final administration of the study instruments, the major findings are : 1 - Third year EFL college students' performance on the critical thinking test is average.2 - The students have average level in some CT subskills; Interpretation and Evaluation of Arguments, but they are weak on others; Inference, Recognition of Assumptions and Deduction. 3 - Third year EFL college students' performance on the reading comprehension test is average. 4 - The students' performance on the lower order thinking level is average, whereas their performance on the higher order thinking level is below average.5 - There is a positive significant relationship between Iraqi EFL students' critical thinking skills and reading comprehension performance.6 - There are no statistically significant differences between critical thinking and reading comprehension due to the gender variable.In the light of the results obtained, a number of pedagogicalimplications and recommendations concerned with textbooks designers, teachers, and learners are put forward. Also, several suggestions for further studies are proposed to enrich this area of investigation.

Abstract: معرفة مدى فعالية استخدام اسلوب(التمثيل المسرحي) في تدريس محاورات المواقف التعليمية (Situational Dialogues ) على تحصيل طلاب الكلية الذين يدرسون اللغة الانكليزية باعتبارها لغة اجنبية.معرفة ما اذا كان استخدام اسلوب التمثيل المسرحي قد اثر بنسبة متساوية او م | 1. The effect of using dramatization as a teaching technique on the achievement of EFL college students in Situational Dialogues (SDs).2. Whether using dramatization in teaching English conversation has an equal or different effect on students' written and oral achievement in Situational Dialogues (SDs).To achieve these aims, three hypotheses have been formulated as follows : 1. There is no significant deference in the mean scores of the written achievement test between the experimental group which is exposed to dramatization, and that of the control group which is not exposed to dramatization. 2. There is no significant difference in the mean scores of the oral achievement test between the experimental group which is exposed to dramatization, and that of the control group which is not exposed to dramatization.3. There is no significant difference between the mean scores of the experimental group's written achievement and that of their oral achievement in Situational Dialogues (SDs).The present study is limited to the first year EFL college students in the College of Education / Ibn - Rushd at Baghdad University in the academic year 2004 - 2005 and to the textbook of conversation taught at the first stage entitled : "Situational Dialogues" written by Micheal Okenden (1972). The experimental design decided is the type of "the post - test only control group design". The sample of the study consists of sixty students selected randomly out of 160 students which represent 37.5 percent of its original population. The chosen sample is divided into two equal groups, the experimental and control which have been equalized in the variables of : age, average of achievement in the General Baccalaureate Examination of the previous year, the parents' level of education, and students' scores in English of the previous year. The experimental group has been taught according to dramatization technique while the control group has been taught according to the traditional technique, i.e. without dramatization.At the end of the experiment, the two groups are subjected to oral and written achievement tests. After the administration of the two tests to the selected sample, testees' responses have been processed statistically using the appropriate statistical means.The obtained results reveal that : 1 - The mean scores of the experimental group's written achievement is 77.40, whereas that of the control group is 70. 2 - There is significant difference between the two groups in written achievement test, in favour of the experimental group at 0.05 level of significance and with 58 degree of freedom.3 - The mean scores of the experimental group's oral achievement is 78.67, whereas that of the control group is 65.37.4 - There is significant difference between the two groups in oral achievement test, in favour of the experimental group at 0.05 level of significance and with 58 degree of freedom.5 - The mean scores of the experimental group's oral achievement is 72.52, whereas that of the written achievement is 73.72.6 - There is no significant difference at 0.05 level of significance and with 118 degree of freedom between the oral achievement, on one hand and the written achievement , on the other hand of the experimental group. Later on, a number of recommendations and suggestions are stated; the following are some of them : Recommendations : 1. It is necessary to use dramatization as a teaching technique in teaching Situational Dialogues for EFL first year college students.2. The necessity of putting students in actions and active situations, and motivate them to dramatize and act out roles during teaching EFL subjects and especially Situational Dialogues. 3. A pamphlet which includes a full explanation for each situation by using dramatization technique and how to employ it inside the classroom could be supplied to teachers of Situational Dialogues.4. Constructing TV programme that depends on utilizing dramatization technique in teaching English dialogues for primary, secondary and intermediate stages.Suggestions : 1. Experimenting the effectiveness of using dramatization in teaching other English subjects like (grammar, composition, poetry, novel, drama, etc).2. Conducting similar studies for teaching English by using dramatization at other academic stages especially at the primary & secondary stages.3. Making a comparative study between the efficiency of dramatization and other new teaching techniques in developing students' achievement at the various levels of study such as : primary, secondary, etc.

Abstract: Genre - based approach offers a valuable resource for both pre - and in - service writing instructors to assist their students to produce effective and relevant texts. Instead of focusing on the process of composition, the content of texts, or the abstract prescriptions of disembodied grammars, genre approach enables teachers to ground their courses in the texts that students will have to write in their target contexts, thereby supporting learners to participate effectively in the world outside the EFL classroom.The current research aims at investigating the effect of using genre - based approach as a teaching technique on Iraqi EFL learners’ performance in essay writing.The current study is hypothesized that there are no statistically significant differences between the performancet mean score of the experimental group (taught essay writing by using genre - based approach) and that of the control group (taught essay writing according to the method stated in the Teacher’s Guide).The population of the study consists of fifth - grade male students/scientific branch at the secondary stage in the city of Baghdad during the academic year 2013 - 2014. The experiment of the study lasted two months. It started on 26th of February and ended on 27th of April, 2014.The sample of the study has been intentionally chosen from among male secondary school students in the city of Baghdad. Itconsists of 65 students. The non - equivalent posttest control group has been chosen as the experimental design. Therefore, the first group represents the experimental group which has been taught by using genre - based approach, and the second group represents the control group which has been taught according to the method stated in the Teacher’s Guide.Pre and post written tests are designed and exposed to a jury for the purpose of ascertaining their validity. The inter - rater Pearson correlation coefficient formula is used to calculate the tests reliability yielding coefficients of 0.82 which is considered an acceptable coefficient.At the end of the period of the experiment, the post - test is administered. The mean of the experimental group is 65.906, and the mean of the control group is 58.757.The t - test formula for two independent samples is conducted. The results of the analysis indicate that there is a statistically significant difference between the experimental group and control group where the experimental group proved to be better than the control group.In accordance with the results obtained, some conclusions, recommendations and suggestions for further studies on the topic have been stated.

Abstract: lustering, which is partitioning data into groups of similar objects, has a wide range of applications. In many cases, unstructured data makes up a significant part of the input.Attempting to cluster such part of the data, which can be referred to as noise, can disturb the clustering on the remaining domain points. Despite the practical need for a framework of clustering that allows a portion of the data to remain unclustered, little research has been done so far in that direction. In this thesis, we take a step towards addressing the issue of clustering in the presence of noise.Clustering is being widely used in many applications including medical, financial, etc. Clustering may be applied on database using various approaches, based upon distance, density, hierarchy, and partition. The data item which is not relevant to data mining is called noise. Noise is a major problem in cluster analysis, which degrades the performance of various clustering algorithms in the term of efficiency and time.The objective of this thesis is to study the noise effect on the performance of various clustering algorithms. Propose a new clustering algorithm that the noise effect is very low compared with the other clustering algorithms.Our purpose is to study how a proposed algorithm is responsive to the noise in the efficiency. K - mean algorithm and our proposed clustering algorithm used based upon the partitioned or hierarchical clustering. Different types of noise add to selected database then measure the effect of that noise on the result of clustering algorithm (proposed algorithm and K - mean algorithm).The challenge of our proposed algorithm to the noise is study by computing the efficiency, the time and the obtained clusters number. Then the percentage of noise will be varied, the efficiency and the time required for clustering, will be calculated. The observation results will be used to compare the efficiency of algorithms and the processed time.The proposed clustering algorithm and other algorithms used in our study have been implemented using (MATLAB R2014b) programming language, and the programs work under windows 7 Ultimate service pack1 operating system type (32 - bit). The tests have been applied using a personal computer (Core i5, processor 2.60 GHz, RAM 6 G - byte).A real - world database containing 200 images has been constructed during thesis time. We do some experiments to demonstrate the power of the proposed algorithm.The results showed that the proposed clustering algorithm efficiency is not affected by the presence of noise but it efficiency is less if the noise ratio is increased.

Abstract: تستخدم عدة انواع من الدوال الفوضى في تشفيرالمعلومات بدلا من التشفر التقليدي لامتلاكها ميزات مهمه.في هذه الرسالة تم تقييم ستة انواع من دوال الفوضى. ودوال الفوضى هي logistic map, tent map, circle map, Bernoulli map, ICMIC map وdyadic map.وتضمنت الرسالة : - اختبار توحيد العشوائية لجميع المتسلسلات المتولدة من دوال الفوضى. - تحويل المتسلسلات من النظام العشري الى نظام الثنائي باستخدام CCCBG(Cross Coupled Chaotic Bit Generation). - اختبار المتسلسلات الثنائية الناتجة باستخدام خمسة عشر اختبار صادره من المعهد التقني للمعايير والتكنولجيه NIST)).نتائج الاختبار لستة دوال الفوضى تشير ان logistic map, tent map, circle map, Bernoulli mapو map ICMIC نجحت خلال الاختبار بينما dyadic map لم تنجح. من خلال اختبار توحيد اظهرت النتائج ان tent map, circle mapو Bernoulli map هي موحدة بينما logistic map, ICMIC map وdyadic map غير موحده .تم تنفيذ الخوارزمية لتشفير الكلام باستخدام كل سلسله متولدة من دوال الفوضى. الخوارزمية المقترحة استخدمت سلسلة الدوال كمفتاح. تم الاستعانه بخمس انواع من المقاييس لتنفيذها على الكلام المشفرومقارنته مع الكلام الصريح. ان نظام التشفير يوفر كلام مشفر مع نسبة وضوح قليلة جدا, عندما استخدام دوال التي تمتلك العشوائية (نسبة الاشارة الى الضوضاء SNR ونسبة الاشارة الى الضوضاء المقطعي SNRseg ونسبة الاشارة الى الضوضاء المقطعي الطيفي SSNRseg تصل الى 28 - وقيمة معامل الارتباط تقترب من الصفر), بينما عندما استخدام الدوال التي لاتمتلك العشوائية (نسبة الاشارة الى الضوضاء SNR ونسبة الاشارة الى الضوضاء المقطعي SNRseg ونسبة الاشارة الى الضوضاء المقطعي الطيفي SSNRseg تصل الى 23 - وقيمة معامل الارتباط تقترب من الصفر) . نتائج الاختبار تشير ان العشوائية ليس لها تاثير على التشفير. نفذ العمل العملي لهذه الرسالة بلغة البرمجة الماتلاب. | Several types of chaotic maps have been used broadly in media encryption rather than the traditional encryption because of the important features the chaotic maps have. In the present thesis, an evaluation process has been done for six types of chaotic maps. The chaotic maps used are logistic map, tent map, circle map, Bernoulli map, ICMIC (Iterative Chaotic Map with Infinite Collapses) map and dyadic map. The sequences generated from each chaotic map are tested for uniformity and randomness. The relation between randomness, uniformity and highly security are studied. The fifteen tests of NIST (National Institute Standards and Technology) are implemented in binary randomness test while CCCBG (Cross Coupled Chaotic Bit Generation) is chosen for converting real numbers to binary. The results of testing six chaotic maps indicate that the logistic, circle, tent, ICMIC and Bernoulli are passed through NITS tests while dyadic is not. Circle map, tent map and Bernoulli map are a uniform distribution while Logistic map, ICMIC map and dyadic map are not uniform. Also, each sequence generated from the chaotic maps has been used for speech encryption. A proposed algorithm is proposed and implemented for this task using the chaotic sequences as a key. The encrypted speech is tested using five types of measurements. The results indicate that the encryption system provides encryption speech signal of very low residual intelligibility, when used chaotic have randomness (SNRseg and SSNRseg are very low up to - 28 and correlation closed to zero), while when used chaotic map do not have randomness (SNRseg and SSNRseg are very low up to - 23 and correlation closed to zero). The results show that the randomness does not have effect on speech encryption. The practical work of the thesis is implemented in Matlab programming language

Abstract: شبكة العصبية الذاكرة ثنائية الاتجاه الترابطية (BAM) هي واحدة من الاكثر استخداما نماذج الشبكة العصبية لمغاير الجمعيات والتحسين المهام. وBAM لها عدة قيود مثل انماط محدودة المخزنة، مشاكل ادنى المحلية، نسبة الضوضاء المحدودة والتحول والمشاكل التحجيم. واقترحت هذه الاطروحة لتحسين شبكة الذاكرة العصبية ثنائية الاتجاه الترابطية (BAM) عن طريق تعديل في هيكلية الشبكة وعمليات التعلم والتقارب. هذا التعديل يؤدي الى زيادة اداء الشبكة العصبية الذاكرة ثنائية الاتجاه الترابطية (BAM) عن طريق تجنب معظم القيود. وبالاضافة الى ذلك تحسين كفائتها من خلال تقليل حجم الشبكة وحجم الوزن. ونتيجة ما ورد اعلاه، سيتم زيادة القدرة على الضوضاء، وكذلك تسريع عملية التعلم وتقاربه. اثبتت عملية التقييم ان شبكة (MBAM) يمكن ان تتعلم وتتعرف على (100) انماط ذات احجام مختلفة وبنسب مقبوله من الضوضاء والتغلب على معظم القيود BAM باستثناء المشاكل التحول والارتقاء. وفقا لمرحلة التعلم، وصلت MBAM سعة التخزين الى 100 انماط ومازالت تعمل بكفاءة. وبالاضافة الى ذلك، فان حجم المصفوفة الاوزان اصبح اصغر (اي اربعة مصفوفات)، ويتم تحديد حجم هيكل شبكة MBAM (اربعة الخلايا العصبية) مع اي حجم نمط (اي انها لن تعتمد على حجم نمط). في مرحلة التقارب، والتخلص من مشكلة الارتباط ومشكلة الحد الادنى المحلية. وبالاضافة الى ذلك، كانت نسبة الضوضاء مقبولة لخوارزمية التقليدية مع حجم نمط (32 * 32) بكسل والضوضاء وتتراوح ما بين (10٪ - 90٪). وكانت نتائج هذه التقييم من (100٪ - 36.66٪)، في حين كان من نتائجها خوارزمية عشوائية في مجموعة من (100٪ - 39.66٪)، ونتائج خوارزمية الربع في مجموعة من (100٪ - 36٪). | A Bidirectional Associative Memory (BAM) neural network is one of the most commonly used neural network models for hetero - association and optimization tasks. The BAM has several limitations such as limited stored patterns, local minimum problems, limited noise ratio and shifting and scaling problems. This thesis will proposed to improve the Bidirectional Associative Memory neural network (BAM) via modification the network architecture, learning and convergence processes. This modification is to increases the performance of associative memory neural network via avoiding most of the (BAM) limitations. In addition improving its efficiency by decrease the network size and weight size. As a result of the above, the capability for noise will be increased as well as speed up its learning and convergence process. The evaluation process proved that the MBAM network can learn and recognize 100 patterns with different sizes in acceptable percentage noise overcoming most of BAM limitations except shifting and scaling problems. According to the learning phase, MBAM reached the storage capacity to 100 patterns and still working efficiently. In addition, the size of the weights matrix became smaller (i.e. Four matrices), and the structure size of the MBAM network will be fixed (Four neurons) with any pattern size (i.e. it will not depend on the size of the pattern). In the convergence phase, the correlation problem and local minimum problem were disposed. In addition, noise percentage was acceptable that for traditional algorithm with pattern size (32*32) pixel and the noise was ranging from (10% - 90%). The results of these evaluation was from (100% - 36.66%), while Random algorithm was resulted in range from (100% - 39.66%), and Quarter algorithm was resulted in range from (100% - 36%).
