The Effect of OReillys Strategy in Evaluating the Arguments and Uncovering the Mistakes and Mathematical Errors of the Third Grade Students in Mathematics

The purpose of the research is to know the effect of O'Reilly's strategy in evaluating the arguments and uncovering the fallacies and mathematical errors for The third grade students in mathematics. In order to achieve the research objective, the researcher adopted the research methodology of the two groups (experimental and control) with the post-test. Zero hypotheses were developed for research. the research community was selected or determent, which represents the third grade students of the Directorate of Education Rusafa first, The sample was selected randomly (71) students, and the sample was divided into two experimental and control groups. Parity between the two groups was performed in the variables (evaluation of the arguments, the detection of inaccuracies, the chronological age) For the purpose of collecting the data for the experiment, a test was constructed to evaluate the arguments in the final form of (9) the test of the objective type and one question of the type of pans, and the test of the detection of inaccuracies in the final form of (9) experimental paragraphs of the objective type The appropriate statistical analyzes were performed, and the cytometry properties of the two tests were ascertained. The results showed that the experimental group's students who studied according to O'Reilly's strategy succeeded over the students of the control group who studied according to the usual method in the variables of evaluating the arguments and discovering the fallacies and mathematical errors
