Science learning outcomes, especially vibration and wave material, are not optimal. The enthusiasm of students in participating in learning is less than optimal, which is indicated by the number of students who are less focused, less disciplined, and less active. To improve the science learning outcomes of vibration and wave material, research was conducted using the Discovery Learning model in class VIII D SMP Negeri 1 Tegalrejo, totaling 30 students. This research is a type of classroom action research conducted with two cycles. The method of data analysis of the research results used is descriptive quantitative and descriptive qualitative. From the initial test results of the cycle there were 9 students who completed learning individually with a percentage of learning completeness of 30%. In the first cycle test results, 20 students were declared individually complete with a percentage of learning completeness of 73.33%, while in cycle II the number of students who were individually complete was 26 students with a percentage of learning completeness of 86.67%. Based on the results of the study, it can be concluded that learning using the Discovery Learning model can improve the learning outcomes of IPA vibration and wave material in students of class VIII D SMP Negeri 1 Tegalrejo.
科学学习成果，尤其是振动和波的材料，并不理想。学生参与学习的热情不高，这表现在学生的注意力不集中、不守纪律、不积极。为了提高振动和波浪材料的科学学习成果，我们在八年级 D SMP Negeri 1 Tegalrejo 班开展了探索学习模式研究，共有 30 名学生参加。本研究是一种课堂行动研究，分两个周期进行。研究结果的数据分析方法是描述性定量分析和描述性定性分析。从周期的初始测试结果来看，有 9 名学生单独完成了学习，学习完成率为 30%。在第一周期的测试结果中，有 20 名学生被宣布单独完成了学习，学习完成率为 73.33%；而在第二周期中，单独完成学习的学生人数为 26 人，学习完成率为 86.67%。根据研究结果，可以得出结论：使用发现式学习模式可以提高八年级D班（SMP Negeri 1 Tegalrejo）学生对IPA振动和波材料的学习效果。

This research aims to increase the understanding of the concept of pressure in Class VIII students of Kanda One Roof Junior High School through the PBL Learning Model with Demonstration and Practice Procedures. This type of research is a type of Classroom Action Research (PTK) which focuses on the classroom atmosphere which is often called Classroom Action Research. The research population is class VIII students of SMP Satu Atap Kanda, one class is taken randomly, namely class VIII B. The method of analyzing information in this matter is tried to use statistics, tabulating information based on variables obtained from all respondents, Descriptive Statistical Test and T-test Analysis Method. Based on the results of this research, the description of the concept of pressure in Kanda One Roof Junior High School students has increased. This shows that there is a change in the increase in the students' concept description in the PBL learning model with demonstration and practice procedures.
本研究旨在通过 "示范与实践程序 "的 PBL 学习模式，提高神田一顶初级中学八年级学生对压力概念的理解。这类研究属于课堂行动研究（PTK）的一种，主要关注课堂气氛，通常被称为课堂行动研究。研究对象是 SMP Satu Atap Kanda 学校八年级的学生，随机抽取一个班级，即八年级 B 班。分析信息的方法是尝试使用统计学、基于从所有受访者那里获得的变量的表格信息、描述性统计测试和 T 检验分析法。根据本研究的结果，神田同一屋檐下初中学生对压力概念的描述有所增加。这表明，在有示范和练习程序的 PBL 学习模式中，学生的概念描述有了增加的变化。

One of the principles of merdeka curriculum is meaningful and enjoyable learning that is designed according to students' needs. The application of these principles can be carried out at various stages of learning, including during formative assessments. The aim of this research is to analyze the use of Gimkit for formative assessment for students on the topic of colligative properties of solutions. The research was conducted in a descriptive qualitative manner with three stages of activities, namely preparation, implementation and reflection. Based on the reflection results, it is known that the use of Gimkit for formative assessment of the colligative properties of solutions was stated as good or very good by 95.8% of students. This is reinforced by the results of observations that students took part in the formative assessment with enthusiasm.
