The use of practical methods in teaching material on changes in the states of matter is very effective in helping students understand these concepts in more depth. Through practicum, students can directly observe how a substance changes form under certain conditions, such as temperature or pressure, this strengthens theoretical understanding with practical experience. Using practical methods in teaching changes in the states of matter, students not only understand theoretical concepts but also see their application in real life. This can help build a more holistic and in-depth understanding of the material studied. The practicum method encourages students to be more active and participate in the learning process. Class observations showed that 85% of students were more engaged and enthusiastic during practicum sessions compared to conventional learning. They often ask questions, discuss and try to understand the material through direct experiments. Students are trained to make careful and systematic observations of changes in the state of substances. The evaluation results show an increase in these skills by 25% after implementing the practicum method. The application of practicum methods in learning science and material regarding changes in the states of substances in class IV has proven to be effective in improving various aspects of learning. This method succeeded in increasing conceptual understanding, science process skills, student activity and participation, academic performance, and learning motivation. Students involved in practicum activities showed a significant increase in understanding the concept of changes in the states of matter, as shown by an increase in the average score of 30%.

The implementation of science learning in schools has complex and varied challenges. This research aims to identify several general problems that arise in the implementation of science learning and find solutions that can increase the effectiveness of this learning. The problem of implementing science learning in class VI at SDN Pegangsaan Dua 05 this morning does not have too many challenges, because it suits the students' interests. The strategy is carried out through approaching students and conducting peer tutoring. It is hoped that this research will enable teachers in elementary schools to evaluate teaching results in class. Parental involvement in science learning is very lacking, but the role of parents in helping with the practical tools to be used is sufficient and very helpful.

This research aims to determine the effectiveness of practicum activities to improve student learning outcomes at SMA Negeri 2 Tondano. This type of research is quantitative descriptive research that uses a survey method to describe and explain data based on the reality in the field. The research was carried out by distributing questionnaires to teachers and students, observation sheets, and practical activity sheets with data sources consisting of 30 students of class X Science 1, 30 students of class X Science 2, and biology teachers. Based on the research results, the level of readiness to obtain data for class X IPA 1 At the implementation stage of the practicum activities for class X Science 1 is 91%; the efforts made to improve the quality of practicum implementation are by improving practicum weaknesses such as the availability of tools and materials, good laboratory management, conducting evaluations, arranging implementation schedules and paying attention to laboratory layout in order to carry out practicum optimally. The factors that influence the quality of practicum implementation include student motivation, limited tools and materials, practicum schedule, availability of facilities and infrastructure, teacher's role in practicum activities, and students' active thinking.
