The demand for the integration of technology to improve the quality of education in the 21st century, in order to achieve innovative leaning and enchance students’ understanding of subject, serves as the background of this study. The aim of this research is to examine the relationship between the Blended Learning method using Google Classroom and students’ conceptual knowledge ability. The population of this study consists of XI-1th-grade students at SMA Negeri 1 Siabu, Mandailing Natal Regency. The sampling method used in this study is purposive sampling, selecting 30 students froms class XI-1 as the research sample. The instruments used in this study are test questions and questionnaries. The data analysis technique employer is correlationa analysis with prerequisite testing. The results of study show a very strong positive relationship between Blended Learning using Google Classroom and students conceptual knowledge, as indicated by mulitiple correlation coefficient (R) of 0.9935 and a determination coefficient of 98.65%.

This study aims to obtain information about the Application of the Argument Driven Inquiry (ADI) Learning Model to Improve the Problem Solving Ability of Students of Class X Energy Business at SMA Negeri 1 Sinunukan. This research was carried out systematically, class X SMA Negeri 1 Sinunukan in the academic year 2023/2024, totaling 30 people. The type of research is Classroom Action Research following Kurt Lewin's model consisting of four steps, namely planning, action, observation, and reflection. Classroom Action Research with the cycle method. Qualitative research instruments are data reduction, data exposure, and data inference. The results showed that the students' understanding of physics learning on Energy Business increased by applying the Argument Driven Inquiry (ADI) learning model to improve the problemsolving ability of eighth grade students of SMA Negeri 1 J Sinunukan.

This study aims to determine the effect of Model Based Learning on physics problem-solving abilities of tenth-grade students at SMA Negeri 2 Padangsidimpuan. The research employed a quantitative approach with a quasi-experimental pretest-posttest control group design. The sample consisted of 60 students divided into an experimental class (30 students) and a control class (30 students) selected through purposive sampling. Problem-solving ability data were obtained through validated tests based on Polya indicators, including: understanding the problem, devising a plan, carrying out the plan, and looking back. Data analysis included descriptive statistics, normality tests, homogeneity tests, and independent t-tests. Results showed that the experimental class achieved an average problem-solving ability score of 82.47 (high category), while the control class achieved 68.23 (moderate category). The t-test revealed a significant difference between both groups (t-calculated = 5.872 > t-table = 2.001; p < 0.01). The N-Gain value for the experimental class was 0.71 (high category), while the control class was 0.42 (moderate category). This study confirms that Model Based Learning effectively improves high school students' physics problem-solving abilities
