Abstract

Low mathematics scores are related to students' reasoning abilities. The reasoning process is very important to train in students to train their thinking development abilities, especially in solving problems. This research aims to analyze mathematical reasoning abilities in terms of thinking abilities in grade 4 elementary school students. The research subjects were 4th grade students at SD N 3 Kandangmas, Kudus, totaling 4 students with the highest scores in each indicator of mathematical reasoning using a purposive sampling technique. The instruments used in this research were an interview sheet and essay questions consisting of 4 questions with flat shapes and indicators. The research results show that students' mathematical reasoning abilities in solving mathematical reasoning-based problems at school are quite sufficient. Of the 4 indicators, 2 indicators can be fulfilled correctly and well, 1 indicator has not been fulfilled properly, and 1 indicator has not been fulfilled.

Abstract

Introduction/Main Objectives: The purpose of this study was to improve the learning outcomes of fourth grade students at SD 5 Karangbener on the material of ethnic diversity and local wisdom through the application of the Project Based Learning (PjBL) model with diorama media. Research Methods: This research used a Classroom Action Research (PTK) approach carried out in two cycles, with steps of planning, implementation, observation, and reflection. Finding/Results: The results showed that before the application of PjBL, only 26.32% of students reached the Criteria for Achievement of Learning Objectives (KKTP). After the application of PjBL in the first cycle, the percentage of completeness increased to 57.89%, and in the second cycle it reached 89.5%. In addition to the quantitative improvement in learning outcomes, observations also recorded student participation and enthusiasm in the learning process. Thus, it can be concluded that the application of the PjBL model supported by diorama media has a positive effect in improving students' understanding of the material and fostering a positive attitude towards cultural diversity. Conclusion: This research recommends the use of PjBL as an effective learning method at the elementary level.
