Abstract:
The research aims to identify the effectiveness of John Zahorek's model in : A) Achieving of the second grade students of the middle school in physics. B) Science operations of the second grade students of the middle school. To verify this objective the following two hypotheses were formulated : 1) There is no statistically significant difference at the level of significance (0.05) between the average grade of the students of the experimental group which will be studied according to the John Zahorek model and the mean of the control group that will be studied according to the usual method in the achievement test of physics. 2) There is no statistically significant difference at the level of significance (0.05) between the average grade of the students of the experimental group that will be studied according to the John Zahorek model and the mean of the control group that will be studied according to the usual method in the science operations scale. The research was determined with the students of the second grade intermediate in the middle and secondary schools of the government in the center of the province of AL - Najaf and the physics of the last four study seasons which they are (light and its reflection , refraction of the light, thin lenses , electromagnetic waves) For the academic year (2016 - 2017) AD and the researcher intentionally chose an intermediate school for boys of Al - Masjid Al - Haram that affiliated to the Directorate of Education of Al - Najaf to represent a place to conduct the experiment.The researcher adopted the experimental method and the micro - experimental design was used in two equal sets of post - test for achieving and measuring of the science operations. The two classrooms were chosen in a random cloud manner and the classroom B represents the experimental group and the classroom A represents the control group. The study sample consisted of (70) students where (35) students of the experimental group studied according to John Zahorek model and (35) students of the control group studied according to the usual method. The researcher evaluated the research groups statistically in a series of variables (age calculated in months, previous academic achievement in physics, intelligence level, parents' achievement, the scale of science operations) Preparation of teaching plans). The researcher also prepared the research requirements of (defining the scientific subject, formulating the behavioral objectives, preparing teaching plans).The researcher prepared two tools ; the first tool is (the achievement test) which in its final form will consists of (40) thematic paragraphs of the type (multiple choice) with four alternatives. The virtual honesty and the content honesty have been verified and the coefficient of difficulty and the coefficient of the discrimination and the effectiveness of alternatives to the substantive paragraphs were extracted. The stability of test paragraphs was found in two ways which they are ; Split half Reliability method which it was reached to (0.89) and the internal consistency method (Kyudar Richardson 20) which it was reached to (81.0). The second tool is the (Scale of Science Operations) ) which in its final form will consists of 32 paragraphs that distributed evenly over the basic science processes which they are (observation, classification, inference, prediction, measurement, communication, numbers use, temporal and spatial relations) and its virtual honesty and its construction honesty and the forces of discrimination of its paragraphs and the calculation of stability was verified in two ways which they are ; Split half Reliability method which it was reached to (0.87) and the internal consistency method (Kyudar Richardson 20) which it was reached to (0.81). The experiment was applied in the second semester of the academic year (2016 - 2017) and lasted for 16 weeks and with two classes per group. After the experiment the research tools were applied to the two research groups.The data were processed statistically by using the following statistical means : (The test of two independent samples , the square of Kai , the coefficient of difficulty , the equation of discrimination , Pearson correlation coefficient , equivalent to the effectiveness of the wrong alternatives, the Spearman - Brown equation , equation of Kyudar Richardson 20 , Aita equation). Research results showed : 1 - Excellence of students of the experimental group that studied according to the model of John Zahorek on the students in the control group which studied according to the usual way in the collection of physics and the size of the impact of (1.22) which it is a large indicator.2 - Excellence of the students of the experimental group which studied according to the model John Zahorek on the students of the control group which studied according to the usual method in the scale of science operations and with size of the impact (1.22) which it is a large indicator.In the context of the research results the researcher came out with a set of conclusions and recommendations and suggestions.
