The purpose of this study is to improve teacher performance through the implementation of academic supervision. The research method used is School Action Research (PTS) with a quantitative descriptive approach. Data collection techniques with observation, interviews, and documentation. Research results shows that academic supervision shows an increase in scores in aspects of learning planning and implementation. Although it is still in the sufficient category, it is because it continues to eventually increase. This result can be achieved because of good cooperation between the Principal and supervised teachers. The Principal discusses with the teacher the problems faced by the teacher in the process of planning and implementing lessons. Academic supervision carried out by the Principal is an effort to improve teaching, including stimulating, selecting the growth of positions and the development of teachers and revising learning objectives, teaching materials, methods, evaluation or assessment of teaching. Academic supervision can help teachers to learn and understand their duties and roles as educators.

Implementation of the VARK Model (Visual, Auditory, Reading/Writing, Kinesthetic) in the context of classroom mastery is a strategy that can provide a more inclusive and effective approach in increasing student achievement. This research aims to explore how implementing the VARK model can improve students' learning experiences and their academic performance. The research method used is a literature study which involves analysis of relevant sources regarding the VARK concept and its application in an educational context. The research results show that by understanding diverse learning preferences, educators can design learning experiences that better suit students' individual needs. Through the integration of different learning strategies, such as the use of pictures and diagrams for visual students, group discussions for auditory students, reading and writing assignments for students who prefer learning through text, as well as practical activities or experiments for kinesthetic students, students can be more engaged in learning and gaining a deeper understanding. This research also highlights the importance of flexibility in teaching, adapting to changing student learning preferences, and evaluating the effectiveness of the learning strategies used. Although the VARK model has advantages in providing guidance for inclusive teaching, it is important to remember that students' learning preferences can change and that various factors also influence students' academic performance.

This research aims to determine the implications of collaborating group discussion methods with Problem Solving Learning in improving students' problem solving skills at SDN Pelita Jaya. This research uses qualitative research methods with a mini research approach to gain in-depth insight into interactions between students in structured learning. For three weeks, research was conducted at SDN Pelita Jaya involving sixth grade students. The group discussion method is used to facilitate student interaction in discussing Islamic ethical and moral values.
