Abstract

This study aims to examine the application of the demonstration model in learning Islamic Religious Education (PAI) with a focus on Fardhu Kifayah material and its impact on improving student learning outcomes in class XI Science at SMAS Plus Muhammadiyah in Subulussalam. The research method used is Classroom Action Research (CAR) with three cycles. The research data were obtained through observation, written tests, and document analysis. The demonstration model is applied in each cycle with structured steps and actively involves students in the practice of Fardhu Kifayah. The results showed a significant increase in student learning outcomes after the implementation of the demonstration model. The conclusion of this study is that the application of the demonstration model in PAI learning Fardhu Kifayah material can provide positive benefits in improving student learning outcomes. This model allows students to see and experience Fardhu Kifayah's practice firsthand, which helps increase students' understanding, skills, and motivation in carrying out the ritual.

Abstract

Abstract: The purpose of this study was to determine the effect of using the Two Stay Two Stray (TSTS) cooperative learning model on student learning outcomes in class XI MIPA 1 SMA Negeri 2 Pulau Taliabu. This research was carried out in the even semester of the 2020/2021 Academic Year from April to May 2021. The research design was in the form of a Pretest Posttest Control Group Design. The population of all students in class XI, amounting to 86 students. The research sample consisted of an experimental class with 22 students and a control class with 22 students, so that the total sample size was 44 students. The instrument used is test questions, in the form of pretest and posttest with a total of 20 multiple choice questions each. The data collected from the test results is processed and tested using the t-test (t-test). to see the influence of the learning model, then to test the hypothesis using the F test, with a significant α = 0.05. Based on the results of the study, the value of tcount > ttable (2.887> 1.682) was obtained, so that it was found that there were differences in the effect of learning outcomes with conventional learning models and two stay two stray learning models. So it can be concluded that there is a significant effect of using the two stay two stray (TSTS) type learning model on student learning outcomes in class XI MIPA 1 SMA Negeri 2 Pulau Taliabu. Keywords: Cooperative Learning; Pulau Taliabu ; Two Stay Two Stray
