    The Effect of Using the Calculator in Math On The Achievement Of The Nineth Elementary Class Students In Nablus
    (2002) Ghena Hasan Khayyat; Dr. Salah Yasin
    The purpose of this study was to compare the results of the groups of study ( two groups) , so as to find out the effect of using the calculator in the classroom and exam on the achievement of the pupils in Mathematics through answering the following questions: l. Are there statistically- significant differences in the student achievement of the two groups of study ( Experimental and Control ) , in the post exam , attributed to the method of learning ( using calculator or do not ) . 2. Are there statistically- significant differences in the student achievement of the two groups of study ( Experimental and Control ) , in the three fields of the post exam , ( Concepts , Calculations , Solving problems ) , attributed to the method of learning ( using calculator or do not). 3. Are there statistically- significant differences in the student achievement between males and females, in the experimental group , on the post exam and the three fields , (Concepts , Calculations , Solving problems). 4. Are there any effects of interaction between sex and group on the student achievement , in the post exam and its three fields ,(Concepts , Calculations , Solving problems) . The sample of the study consisted of ( 256) pupils in the ninth grade in Nablus District ; ( 112 Males , 144 Female ) ; during the second semester of the academic year 2000/ 2001 . The sample distributed on eight sections (four male and four female sections ) . F our sections were chosen ( two male , two female ) to be taught the statistics unit , and were admitted to use calculator during learning and in the test . These two sections were considered as the experimental ones. The other four remaining sections were taught the same material of the same unit , but without using the calculator , and were considered as the control sections . For the purpose of the study the researcher developed a detailed plan consisted of eleven periods ( 45 minutes each ) to be taught for two weeks . In order to control the variables ,the researcher trained the teachers and gave them all the needed instructions . All sections were given equal time regarding the time of the period and the test also . The tools of the study were two tests . A pre—test aimed to measure the achievement of the groups , that is to find out whether their achievements were similar or not . Another post-achieving test to measure the achievement of the pupils . The researcher investigated the reliability of the tools of the study by analyzing their content by using Pearson Formula , which was ( 0.72) for the pre- test, and ( 0.81 ) for the post-test. The Independent T—Test , One-Way ANOVA and Two—Way ANOVA analysis were used to examine the hypothesis of the study . The following results were reached : 1. The achievement of the experimental groups was better than that of the control ones , in the post exam and its three fields (concepts , calculations and solving problems) . 2. The achievement of the females was better than that of the males in the experimental groups on the post exam and its three fields ( concepts , calculations and solving problems ). 3. The sex has a statistically significant influence on the results of the post exam and its three fields ( concepts , calculations and solving problems ) , in favor of females , and the groups in favor of experimental group .
