Abstract

This study aims to determine and describe problem solving abilities based on the stages of thinking about rectangular flat shapes. The technique utilized is expressive subjective. The subjects in this study were seventeen students selected at random with the highest scores being selected by three grade VII understudies of SMP Negeri 2 Pemangkat. The data collection technique used is a test that will be given to the selected subject based on problem solving based on Van Hiele's thinking. The results of describing the data show that there are three subjects who are in the Visualization stage, they know the name of the rectangular shape from the visual form without knowing the nature and conditions of the shape, for the analysis stage the three subjects have not reached, students cannot explain and determine the nature of the requested shape and for the stage of abstraction there are no students who reach this stage, judging by the results of their answers that students have not been able to define a rectangular shape in indonesian itself and have not been ready to decide similar properties between one shape and another.

Abstract

This study aims to describe: the feasibility level of teaching materials developed in the form of Student Worksheets, responses, and student learning outcomes after being given learning. The type of research used isResearch and Development (R&D)with the development model of Thiagarajan . The subjects in this study were the seventh grade students of the Asoka Singkawang Private Junior High School, which amounted to 20 people. The instruments used are questionnaires on the feasibility of teaching materials, student response questionnaires, and posttest questions. Data collection techniques: the feasibility of teaching materials was validated by experts, student responses were given a questionnaire, and learning outcomes were given posttest questions. Data were analyzed descriptively quantitatively. The results obtained: the feasibility level of teaching materials is 87.26% with very feasible criteria for use, student response questionnaires are 87% with very high criteria, meaning that student responses are very good, and student learning outcomes are classically fulfilled, namely 85% of students who achieve grades. minimal completeness. Conclusion: the developed teaching materials can be used in learning. Suggestion: further researchers can develop giving examples in learning mathematics and other learning using more diverse representations.

Abstract

This study aims to improve student learning outcomes with strategies to increase student confidence in class IX A of SMP Negeri 2 Sanggau. This research was carried out in the second semester of the 2021/2022 academic year with learning activities carried out in two sessions, face-to-face meetings (PTM) and learning from home (BDR). The research conducted was classroom action research which consisted of two cycles, and each cycle consisted of two meetings. Each research cycle consists of four stages, namely: planning, action, observation, and reflection. The results showed that with increasing students' self-confidence, the learning outcomes obtained by students also increased as seen from the learning outcomes obtained by students in the first cycle by 75.00% to 87.50% in the second cycle.

Abstract

This research aims to compile a scaffolding booklet using Polya's theory of trigonometric subject. The method of this research is a research and development (R&D) method with a 4-D development model. The research subject are the student of class X MIA 1 SMAN 6 Pontianak. Data collection tools used are unstructured interviews and questionnaires. Data analysis is viewed from the results of the questionnaire assessment, how to develop booklets and booklets. From this research, it was found that the clarity of how to solve trigonometric problems in textbooks used in schools is still not clear, because the completeness of the fourth polya step, namely at the stage of re-examining, does not exist and there are still students who do not understand how to solve the problems given. The preparation of this booklet is to improve and clarify how to solve the problems in the book. The completeness of the polya steps that did not exist before came into existence and the stages of solving Polya's problems become complete in the booklet. Students who do not understand the explanations in the textbooks will at least understand enough when given an explanation of how to solve problems in the booklet.

Abstract

This study aims to determine the ability to solve mathematical problems with the level of self-regulated learning in SMP Negeri 6 Pontianak. The method used in this research is descriptive with the type of qualitative research. The research subjects were grade IX G students who had studied the circle material. The results of data analysis show that students with high levels of self-regulated learning have good mathematical problem solving skills, namely being able to understand problems, plan solutions, implement plans, and re-examine the results obtained. Students with moderate levels of self-regulated learning have good mathematical problem solving skills, namely being able to understand problems, plan solutions, and carry out plans. Students with low levels of self-regulatory learning have low mathematical problem-solving abilities, only fulfilling the first problem-solving step, namely understanding the problem while planning solutions, implementing plans, and re-examining the results obtained by students with low self-regulated learning students have not been able to.
