Abstract

The purpose of this study was to analyze the effectiveness of Project Based Learning-STEM (PjBL-STEM) associated with the variable Mathematical Problem Solving Ability (KPM) on trigonometric material. The research method uses a quasi-experimental design with Nonequivalent Control Group Design. The problem-solving abilities studied include: understanding the problem, planning for completion, completing according to plan, re-examining the calculation results. The results and conclusions of this study are (a) the effectiveness of the learning process of teachers and students can be categorized as good based on the average results on the observation sheet that has been assessed by the observer; (b) based on independent t-test there are differences in the improvement of students' mathematical problem solving abilities who receive STEM-based Project Based Learning (PjBL-STEM) learning with conventional learning, where STEM-based Project Based Learning (PjBL-STEM) learning has an average score N-gain 0.53 higher than conventional learning with an average N-Gain 0.31.

Abstract

This study aims to analyze the use of digital media in mathematics learning in public elementary schools in the city of Bandung. This study uses a descriptive quantitative research design. The study population consisted of teachers and students from public elementary schools in the city of Bandung, with a randomly selected sample from 20 public elementary schools and each school was taken with 5 teachers and 6 students. The instruments used were observations, questionnaires, and documentation to collect data, which included the perception of teachers and students on the use of digital media in mathematics learning. The types of data taken include respondent scores from questionnaires, observation results and documentation which are then analyzed using descriptive statistics to obtain the average score and interpretation. The results showed that teachers actively utilize various digital media in mathematics learning, such as learning videos and educational applications, which contributed to increased student interest and engagement. In addition, students responded positively to the use of digital media, with 84% stating that learning became more engaging and enjoyable. The research also identified major obstacles, such as unstable internet access and device limitations for students. The research concludes that the use of digital media in mathematics learning in primary school can increase students' interest and engagement, as well as help in understanding abstract concepts.
