Abstract

This classroom action research aims to determine whether the implementation of the Problem Based Learning (PBL) learning model can enhance students' problem solving skills on the topic integral in class XII-10 of SHS 4 Semarang odd semester of the 2024/2025 academic year. This research was conducted in two cycles, encompassing four stages: planning, action, observation, and reflection. The subjects of this study were 36 students of class XII-10 of SHS 4 Semarang. Data were obtained through a problem solving ability test. Based on the research and analysis conducted, it was found that the implementation of the Problem Based Learning (PBL) model has a positive impact on improving the problem solving skills of students of class XII-10 of SHS 4 Semarang in the odd semester of the 2024/2025 academic year. This is evidenced by a significant improvement in problem solving skills between Cycle I and Cycle II. In the first cycle, the average score for problem solving skills reached 75.87, but in the second cycle, this average score increased to 87.50. Thus, the application of the Problem Based Learning (PBL) learning model can improve students' problem solving skills.

Abstract

One of the mathematical skills that students must master is the ability to reason mathematically. However, in reality, this skill has not yet been fully mastered by students. This study is a classroom action research conducted over two cycles at SMA Negeri 11 Semarang. The subjects of the study were students from class XII D-1. The purpose of this study are to describe the process of implementing mathematics learning through the Problem Based Learning (PBL) model assisted by GeoGebra as an effort to improve students' mathematical reasoning abilities and learning engagement in class XII D-1 on the topic of ellipses at SMA Negeri 11 Semarang, to determine the improvement in students' mathematical problem-solving abilities in class XII D-1 on the topic of ellipses after mathematics learning through the Problem Based Learning model assisted by GeoGebra, and to determine the improvement in students' learning engagement in class XII D-1 on the topic of ellipses at SMA Negeri 11 Semarang after the implementation of mathematics learning through the Problem Based Learning model assisted by GeoGebra. The results of the study indicate an improvement in students' mathematical reasoning abilities and learning engagement

Abstract

This research is motivated by the results of the pre-cycle in class XI-2 of SMA Negeri 11 Semarang which showed that mathematical representation ability was relatively low with average mathematical representation ability test score of 45 with classical completion percentage of 19% and self-confidence level in moderate category of 49.75%. The purpose of this study was to describe the implementation of PBL assisted by quizizz to improve mathematical representation ability and self-confidence of class XI-2 students of SMA Negeri 11 Semarang in the 2024/2025 academic year. This research is classroom action research with three-cycle design that includes the planning, action implementation, observation, and reflection stages. The indicator of the success of this research is percentage of classical completion of mathematical representation ability test results is 80% reaching KKM 70 and average self-confidence is at least at 75% or very high. The results of this study are the percentage of pre-cycle completion is 19% increasing in cycle I to 55.6%, in cycle II to 69.4%, and in cycle III to 80.6%. While the percentage of pre-cycle self-confidence questionnaire data is 49.7%, in cycle I to 69.14%, in cycle II to 73.53%, and finally reaching 78.08% in cycle III with very high self-confidence category. It can be concluded that implementation of PBL assisted by quizizz can improve the mathematical representation ability and self-confidence of class XI-2 students of SMA Negeri 11 Semarang.
