<![CDATA[This research aims to (1) reveal the effect of problem based and expository learning towards physicsââ¬â¢ learning outcomes, (2) uncover the effect of studentsââ¬â¢ science process skill towards physicsââ¬â¢ learning outcomes, (3) reveal the interaction between studentsââ¬â¢ science process skill and their physicsââ¬â¢ learning outcomes. This study is a quasi-experimental study applying factorial design 2 x 2. The study was conducted from November 2014 to May 2015.àThe population of this research is the whole students of class VIII which comprises of 9 classes in MTS Negeri 1 Mataram. The purposive sampling was chosen as the sampling technique for this study, in which class VIII-8 acted as the experiment class and class VIII-7 as the controlled class. The data collection encompasses data of science process skill, and studentsââ¬â¢ physicsââ¬â¢ learning outcomes (in the cognitive, affective, and psychomotor domains) towards the main material of light. Technique of collecting data of science process and physicsââ¬â¢ learning outcomes in affective and psychomotor domains were done by using observation sheet with certain criteria, while cognitive domain was done through the test.àThe test instrument has previously been through validity test, reliability test, difficulty level, and discrimination index. The data obtained were firstly tested their normality and homogeneity, then continued by the testing of the hypothesis by using two-way analysis of variance (ANOVA). Data analysis technique was done by using ANOVA 2x2 with different cell. The result of this study shows that (1) problem based and expository learning affects physicsââ¬â¢ learning outcomes, (2) studentsââ¬â¢ science process skill affects their physicsââ¬â¢ learning outcomes, and (3) there is no interaction between science process skill and studentsââ¬â¢ learning outcomes.]]>
