Abstract

This study has the objectives, namely first, to find out whether students' mathematical problem-solving abilities can be improved by using external representations. Second, analyzing student activities in learning mathematics by using external representations. Third, analyzing student responses to learning mathematics by using external representations. This research uses classroom action research (CAR) or classroom action testing (PTK) methods. According to O'Brien in Mulyatiningsih, "action research is carried out when a group of people (students) identify the problem, then the researcher determines an action to overcome it." Classroom Action Research (CAR) seeks to develop and reflect on a learning model with the aim of improving learning processes and outcomes. Based on the results of the research, it can be concluded that: learning using external representations can improve mathematical problem solving abilities; it can be seen that there is an increase in the number of students who score above the KKM in cycle II, with the percentage of students who are declared complete (reaching the KKM) at 71.4%, or as many as 20 students are higher than in cycle I, with a percentage of 53.57%, or as many as 15 students who are declared complete. This means that most students have achieved learning mastery resulting from learning through the use of external representations

Abstract

In order to prepare learning that can enhance children's naturalist intelligence, learning methodologies are being examined and described in this study. Descriptive data are employed in the research method, which is a qualitative one. Seven classroom teachers and one school principals or deputy principals served as the study's subjects. Data collection, data reduction, data presentation, and verification or conclusions were all processes in the Miles Huberman analysis of the data. This study found the diversity of strategies applied in preschool, namely by using or applying three stages of strategy in the learning process, namely: first, the planning strategy, which includes the following things: learning objectives, planning indicators to achieve naturalist intelligence, learning program planning, approach planning, methods and techniques, and learning tactics. Second, the implementation strategy stage includes strategies to manage content and learning material, send content and learning material through the media, and manage learning activities. Third, the assessment strategy stage, which includes the assessment of child development and the teacher's teaching ability in the development of the child's naturalist intelligence
