Abstract

This study aimed to describe the process of Appropriateness, validation, feasibility, and effectiveness of using Simalungun ethnic-based teaching materials with application-assisted applications on negotiating text materials for class X SMK. This study was conducted in SMK PAB 5 Klambir V. The research method is Research and Development (R&D) with a 4D model including Definition, Design, Development, and Dissemination with a population as 48 students. This study used a purposive sampling technique with a total of 23 students. The types of data include qualitative and quantitative data. The result of the study is a product of teaching materials in the form of a textbook based on Simalungun Batak ethnic. According to the results of the material expert validation, validator I as 75%, and validator II as 98%. While the results of validation by design experts are validator I as 96%, and validator II as 84%. These data indicated that the teaching materials are valid and feasible to be tested in schools. The materials were tested in SMK PAB 5 Klambir V with a class X TKJ-2 as the sample, the teacher's response was 92%. The data were obtained from questionnaires consisting of the results of a small group trial categorized as "Very Satisfactory", the results of a limited trial categorized as "Very Satisfactory" and the results of a wider trial with the category "Very Satisfactory." These data indicated that the teaching materials are valid and suitable to be used in schools.

Abstract

The use of information technology is currently very developed, especially in the world of education. Various technologies can be used as mathematics learning media. One of the learning media that supports mathematics learning is the Geogebra application. Geogebra is a computer program that can be used to visualize mathematical concepts. This research aims to measure students' mathematical critical thinking abilities with the help of Geogebra in class Classroom Action Research (PTK). The research method used was PTK with two cycles, each consisting of two meetings. Each cycle is carried out with a focus on learning models and critical thinking skills in mathematics. The research results showed that there was a significant increase in learning outcomes in the second cycle compared to the first cycle. The first cycle succeeded in increasing students' learning preparation, interest and attitudes towards lessons, as well as students' learning activities through the Teaching at The Right Level (TaRL) approach. In the second cycle, improvement efforts were made by integrating the Geogebra application and the Culturally Responsive Teaching (CRT) approach, which resulted in consistent improvements in all aspects of observation

Abstract

This research aims to improve students' problem solving abilities in class XI-9 functional material at SMA Negeri 5 Medan for the 2024/2025 academic year, with a total of 36 students through Classroom Action Research (PTK). The method used is PTK with 2 cycles, where each cycle consists of 2 meetings. Each cycle is carried out with a focus on the learning model and TaRL and CRT approaches. The research results showed that there was a significant increase in learning outcomes in the second cycle compared to the first cycle. The first cycle succeeded in increasing learning preparation, interest and attitudes towards lessons, as well as student learning activities through the application of the PBL learning model and the Teaching at the Right Level (TaRL) approach. In the second cycle, improvement efforts were made by integrating the Teaching at the Right Level (TaRL) and Culturally Responsive Teaching (CRT) approaches, which resulted in consistent improvements in all aspects of observation.

Abstract

Teachers need to design learning in a structured manner so that the goals are achieved effectively. The need for creativity in teaching methods aimed at improving the quality of the learning process. The learning model that provides students with the opportunity to develop critical thinking skills is the Problem Based Learning learning model. Problem Based Learning. One approach that can be chosen to improve students' critical thinking skills on a collaborative basis and through integration of local culture and daily life problems is the Teaching at The Righl Level (TaRl) approach. In line with this, this learning can be connected to academic content in real world situations by combining Culturally Responsive Teaching (CRT) approaches. Furthermore, in the Industrial Revolution 5.0 era, education does not only focus on mastering students' cognitive knowledge but also emphasizes other abilities. One technology that can be integrated into learning, allows collaboration with fellow members, has a responsive website appearance and has strong security is Google Sites (G Sites). This research was carried out using two stages, Cycle I and Cycle II. Based on the results of the descriptive analysis, there was an increase in students' critical thinking within the very good criteria
