مدى استيعاب معلمي العلوم في المرحلة الاساسية المتوسطة للمفاهيم الكيميائية الواردة في منهاج العلوم

This study aimed to answer two questions : 1) What is the degree of comprehension of chemical concepts in Basic Curriculum (grades 5-8) by science teachers at Northern Districts of Palestine? 2) What are the effects of certain variables (academic qualification , major specialization , years of experience , grade levels , sex , institution of graduation , and science training workshops attendance on such comprehension? Statistical means and percentage ratio of comprehension were used to answer the first question The second question was changed into nil hypotheses at (α =0.05) To answer the second question of the study, the One way Analysis of Variance, Scheffe's post - hoc test , and the Two way Analysis of Variance, were used . The study showed the following results : 1) Comprehension of chemical concepts by science teachers differed from one field to another, and the total degree of comprehension was low (57.61% ) 2) There were statistically significant differences in ratio of comprehension attributed to academic qualification variable (in favor of degrees higher than B.Sc.), to major specialization variable (in favor of chemistry, physics, biology specialized teachers) , to experience variable (in favor of those having long experience), to grade levels variable (in favor of those who teach higher grade levels) and to science training workshops variable (in favor of those who participated in those workshops). 3) There were no statistically significant differences in ratio of comprehension attributed to sex and institution of graduation variables. 4) There were no statistically significant differences in ratio of comprehension attributed to interaction between academic qualification and years of experience variables. 5) There were no statistically significant differences in ratio of comprehension attributed to interaction and between academic qualification and participation in science training workshops variables. In the light of the above results, the author recommends that science teachers should develop themselves academically . He also recommends that Ministry of Education to earge and facilitate teachers academic growth . It is recommended that the Palestinian Universities ,that teach general sciences, should increase the lecture and laboratory chemistry courses in their study programs. Additional studies , involving higher grade natural sciences , math, social-sciences and Arabic should be conducted
