Abstract

This study aims to determine the feasibility and ability of learners to the instruments developed. This research was conducted at SMA Negeri 6 Pematangsiantarcarriedin the odd semester of the 2023/2024 academic year. The type of research used is R & D (Reaserch and Development) using 3D models. The study was conducted on students who have studied static electricity materials. The samples used in this study were 36 students from Class XII-IPA 3 taken byrandom sampling. Data collection techniques in this study is by way of interviews, tests, and provide a response questionnaire. Data analysis was performed using the person correlation equation with diagnostic tests. The results of this study is a test instrument to measure the ability of students in SMA Negeri 6 Pematangsiantar on static electricity as many as 20 items of diagnostic questionsthree tier multiple choice. The item is already valid measured by the estimated product moment, has a high level of reliability with a value of 0.712, the difficulty level of the item is good. The results of the analysis of the problem items and the analysis of the ability of students showed that the test instruments used are effective in measuring the ability of students in SMA Negeri 6 Pematangsiantar on static electricity.

Abstract

This study aims to determine the effect of the Project Based Learning model on high school students™ science process skills. The type of research used is a quasi experimental research design with a two group pretest posttest design. The population used was students of class XI MIA SMA Negeri 2 Lubuk Pakam, totaling 2 classes. The research sample consisted of two classes, the class taken was XI MIA I as the experimental class and XI MIA III as the control class. The instrument used is a science process skills test in the form of an essay consisting of 10 questions that hav been declared valid by the validator. Based on the results of the study, the average pretest score for the experimental class was 20,68 and the pretest for the control class 18,85. The results of testing the hypothesis showed that a significant value of 0,411 >  0,05 otherwise  is accepted or both classes have the same initial abilities. After applying the Project Based Learning model, the average posttest score of the experimental class was 77,68 and that of the control class was 64,71. The results of testing the hypothesis showed that a significant value of 0,00 < = 0,05, it is stated that  is accepted, meaning that there is a significant influence of the Project Based Learning model on student™s science process skills.
