Abstract

This study aims to improve Grade III students’ mathematics learning outcomes on plane figure material through the implementation of the Project-Based Learning (PjBL) model at SD GMIM Peleloan. The novelty of this study lies in the application of PjBL to help elementary students recognize, compare, classify plane figures, and calculate the number of sides and angles through project-based activities that connect mathematical concepts with concrete learning experiences. This study employed Classroom Action Research (CAR) using the Kemmis and McTaggart model, which consisted of two cycles. Each cycle included planning, action, observation, and reflection stages. The subjects were 8 Grade III students, consisting of 3 female and 5 male students. Data were collected through observation, tests, and documentation. The findings showed an improvement in teacher activity, student activity, and students’ learning mastery. Students’ learning outcomes increased from 60.62% in Cycle I to 92% in Cycle II. Teacher activity improved from 83.51% to 96.25%, while student activity increased from 63.81% to 95.29%. Classical learning mastery also increased from 50% in Cycle I to 87.5% in Cycle II. Therefore, the implementation of the PjBL model can improve students’ learning outcomes and promote more active, meaningful, and student-centered mathematics learning.

Abstract

This study aims to determine the effect of the use of the Problem Based Learning (PBL) learning model and Quizizz learning media on the learning interest of fourth-grade students at GMIM IV Elementary School, Tomohon. This study used a quantitative approach with a one-group pretest-posttest experimental design. The research subjects were 30 fourth-grade students. Data collection techniques in this study included observation, questionnaires with a Likert scale, and documentation. The research instrument was a learning interest questionnaire that measured indicators of feelings of pleasure, interest, attention, active participation, and learning motivation. Data were analyzed using validity tests, reliability tests, classical assumption tests, and multiple linear regression analysis. The results showed that there was an increase in student learning interest after the implementation of PBL and Quizizz. The average pretest score in the experimental class was 62.5, increasing to 85.3 in the posttest, with a difference in increase of 22.8, while the control class only increased by 7.1. The partial test results (t) show that the PBL model has a significant effect on students' learning interest (Sig. 0.000 < 0.05), and the Quizizz media also has a significant effect (Sig. 0.002 < 0.05). Simultaneously, both variables have a significant effect on students' learning interest (Sig. 0.001 < 0.05). Thus, it can be concluded that the use of the PBL learning model combined with the Quizizz media is effective in increasing students' learning interest. Keywords: Problem Based Learning, Quizizz, interest in learning
