Abstract

This development was motivated by the limited learning media and unstable student learning outcomes. The research objective is to develop a practical, effective and valid Domino Nusantara (DORA) media to improve the learning outcomes of elementary school students. This development uses a 4D (four D) model. Before carrying out the pilot phase, expert tests were carried out, namely learning media experts, learning design experts, and material experts. The research was carried out at SDN Mander 1 Tambakboyo in class IV. Based on the results of expert validation, the following percentages were obtained: material expert validation 89.2% (very valid), learning design experts 95.5% (very valid), and media development experts 82.1% (very valid), response teachers are 91.6% and the results of student responses are 91.4%, and the average percentage of results is 91.5% (very practical) learning implementation observation sheets are 92.5% (very effective) and student learning outcomes are 88.4 % of students finished studying. Based on the results of practicality validation obtained from teacher and student responses as well as from the observation sheet on the implementation of learning and student learning outcomes, it can be concluded that the Domino Nusantara (DORA) learning media is effectively used.

Abstract

Critical thinking is an important skill that needs to be developed from elementary school. This study aims to analyze the critical thinking skills of fourth-grade students in solving problems on the topic "Becoming an Environmental Hero." The study used a descriptive qualitative approach with data collection techniques through essay tests and interviews. The analysis of critical thinking skills was based on Perkins and Murphy's indicators, namely clarification, assessment, inference, and strategy. The results showed that students' critical thinking skills were in various categories and relatively low. Most students experienced difficulties in the clarification and assessment stages, which resulted in low ability to draw conclusions and determine problem-solving strategies. These findings demonstrate the need for contextual and process-oriented learning to develop elementary school students' critical thinking skills.
