Abstract

AbstractThe aims of this research were to examine the effect of PjBL on student communicating skill. To achieve the aim, twenty nine students were tested before and after learning through PjBL to measure their communicating skill. The form of this research was Pre-Experimental design with the research plan of  single pre-test  and post-test researching. The taking sample technique used in this research was purpose sampling. According to wilcoxon test, probability score was less then 0,05 (p>0,05) which meant there was a significant difference of communicating skills at between student before and after learning to PjBL. According to glass test, effect size score was 0,6 which meant PjBL have largest effect on oral communicating skill. According to glass test, effect size score was 1,1 which meant PjBL have largest effect on oral communicating skill. Based on the calculating of the effect size , the applying of PjBL  model was  highly effect the student’s communicating skills  of  VII grade students  at SMP Negeri 12 Pontianak. Keywords: Project Based Learning, Communicating Ability, Separation Methods

Abstract

AbstarctThe purpose of this study was to determine the effect of concept attainment approach with conceptual change text on molecular shape materials toward the learning outcomes of students SMAN 1 Sungai Pinyuh. Research form was a quasi-experimental research design with non equivalent control group pretest-postest design. The sampling method used purposive sampling, where the X MIPA 2 class was chosen  as an experimental class and the X MIPA 3 class as the control class. Data collection’s tool used the achievement test in the form of an short answer. Test result by U-Mann Whitney (=0,05) obtained significant 0,000, indicating that there was a difference between the learning outcomes of student who were tought using a concept attainment approach with conceptual change text and students be taught by conventional methode in the molecular shape materials. Concept attainment approach with conceptual change text gave a high influence with effect size value by 1,48. Therefore concept attainment approach with conceptual change text influence students learning outcomes by 56.78%. Keyword: Concept Attainment Approach, Conceptual Change Text, Learning Outcomes
