Abstract

Cramer's rule is used by combining matrix determinant methods applied in the presentation of solving Systems of Linear Equations (SLE). The purpose of this study was to determine the differences in student learning outcomes when using the Cramer Rule assisted by the Sarrus Method using the elimination substitution method on two-loop electrical circuit material. The research method used is the Posttest-Only Control Design experimental method.  The results of this study are evidenced by the results of the hypothesis test which states that there is a significant difference between the learning outcomes of the control class and the learning outcomes of the experimental class. As well as the results of a very positive response from students to the implementation of Cramer's rule assisted by the Sarrus method. Thus, the conclusion of this study is that the implementation of Cramer's rule assisted by Sarrus method is proven to be effective as an alternative solution to solving two-loop electrical circuit problems.

Abstract

Differentiated learning is a form of learning that is oriented to the needs of students. This research is a classroom action research which aims to determine the effect of implementing visual, auditory, and kinesthetic (VAK) learning style-based differentiation in the Problem Based Learning (PBL) model on students' physics learning activities and outcomes. The material used is global warming. This research was conducted in class X-2 of State High School 3 Jember for the 2022/2023 Academic Year. The subjects of this study were of 36 students who were divided into three VAK learning style profile categories. This research includes quantitative descriptive research. The research data collection method used a Likert scale learning style questionnaire, activity observation sheets and written tests to obtain students' physics learning outcomes. The design used in this study was the Tagart and Kemmis model cycles and the data obtained was analyzed using classical learning completeness. The results showed that there was an increase in student learning activities by 20.14% and an increase in student physics learning outcomes classically by 25% and the average level of mastery learning was above the minimum completeness criteria with an increase in the average score of 6.06. Based on the results of the study, it can be concluded that the application of the PBL learning model based on VAK learning style differentiation can increase student activity and learning outcomes.
