مقروئية كتاب علم الاحياء للصف الاول المتوسط وعلاقتها بتحصيل الطلبة ودافعيتهم نحو المادة
The research aims to identify the level of readability of the book Principles of Biology, and the level of achievement, and the level of motivation towards the article, and to see the difference in the level of readability and achievement and motivation toward material when students first grade average variable depending on the sex And find out the direction and strength of the relationship between readability and collection, and readability and motivation toward the material and between achievement and motivation. Adopted a researcher in the study of three instruments, has been building test readability and achievement test, after he followed the steps of scientific reconstructed and check Sedkhma virtual through display on a group of arbitrators and specialists then extract the sincerity of content for the test grades on according to the specification table, but for the stability has been use of factor analysis of variance using the equation Hoyt for test readability and test achievement was the ratio of stability to test the readability 0.68 As for the test grades were of 0.78, as well as the adoption of a measure of motivation prepared (stapes, 2010) after the confirmation of his sincerity virtual and structural and extract stability using equation Alpha Cronbach was of 0.80, applied the tools of the three at different times on the same Peacekeeping Financing of 300 students were selected randomly. When addressing the study data statistically using samples t-test for one sample and two independent samples and Pearson correlation coefficient and analysis of variance using the equation Hoyt. Results showed the following: 1) That most of the performance of students in the first grade average test Readability (style shutdown) is located within Cbati level. 2) That the performance of students in the first grade average achievement test was low. 3) That the sample has a medium motivation toward substance biology. 4) Did not show statistically significant difference in the level of readability of the book Principles of Biology depending on the different sex. 5) Did not show statistically significant difference for the members of the sample in the achievement test. 6) The presence of statistically significant difference in motivation when students first grade average in favor of females. 7) The results showed a Pearson correlation coefficient and the presence of non-correlation function between the three variables (Readability, achievement, motivation towards the article), but the negative direction.
