Abstract

The purpose of this study is to produce a pocket book of valid and practical flat side space material based on the Indonesian realistic mathematics approach (PMRI) and determine the potential effects arising from the development of pocket books and student responses to the developed pocket books. This research is a quantitative study with the design of Research and Development (R&D). The development of this pocket book is carried out through two stages, namely the priliminary (preparation) stage and the formative evaluation stage. The results of this study indicate that the pocket book builds flat side space using the PMRI approach that is produced valid and practical. Valid drawn from the results of revision after being validated by experts based on content, construct, and language. Based on the document analysis of the results of student work during the field test, showed the final test of learning using a pocket book with PMRI approach got a very good category 43.75%, good 28.12%, Quite 15.62%, and less 12.5%, the result data the test is that the learning performed shows good potential effects. Based on the analysis of the results of student responses to the pocket book developed for the indicator of interest in the pocket book obtained 86.09% of students expressed strongly agree, material indicators 79.97% of students agreed and indicators of language 89.32% of students strongly agreed. In conclusion, pocket books developed based on the Indonesian realistic mathematics approach (PMRI) are declared valid and practical to use and have good and interesting potential effects for students.

Abstract

This study aims to develop Student Worksheets (LKS) using the icon of the City of Lubuklinggau (Great Mosque of the As-Salam Taman Kurma) on valid and practical class X trigonometry material. The research method used is the research method of development, Research and Depelopment (R&D) which has been modified into 3-D which in this study uses 3 stages, namely the stage of definition (Define), design, (Design) and development (Develop). Worksheets developed in the level of validity were seen from the expert questionnaire, while practicality was measured from the practicality questionnaire for students. The results of the study, from the analysis of the assessment of four experts namely linguists, material experts, content experts, and media experts showed that the worksheet met valid criteria with an average score of 3.18. While the results of the analysis of the LKS assessment on field trials of students meet practical criteria with an average score of 3.15. In conclusion, the worksheets are designed using the icon of the city of Lubuklinggau with valid and practical trigonometry material Keyword: City Icons, LKS Development

Abstract

The purpose of this study was to develop student work ethics-oriented student worksheets based on guided discoveries on the material of flat side space and to find out the quality of worksheets developed in terms of validity, practicality and potential effects. The method, this research is Research and Dependency (R&D), that is development research that refers to a modified 4-D development model. The instruments used to measure the quality of worksheets developed include validation sheets, practicality questionnaires, walkthroughs and tests. Worksheets that are developed are valid based on validation sheets by experts and are practical based on a practical questionnaire. The potential effects of worksheets developed can be seen from the activities and understanding of students in working on the problems given to the worksheets. The results showed that: (1) the quality of worksheets seen from the aspect of validity included in the valid category with an average score of 3.18; (2) the quality of worksheets seen from the practical aspect is categorized practically with an average score of 3.24; and (3) worksheets have a potential effect on student learning outcomes where 20 students (76.9%) are included in the category of completion while there are 6 students (23.1%) have not been completed with the Minimum Learning Completion (KBM) specified. Conclusion, ethnomatematics-oriented worksheet based on guided discovery developed is declared valid, practical and potential in improving student learning outcomes in the material of flat side spaces.

Abstract

This study aims to determine the ability of students to solve mathematical problems in mathematics learning using the Indonesian Realistic Mathematics Education Approach (PMRI). The data collection technique used the test technique which was analyzed using the t-test at the significant level α = 5%. From the results of the post-test students' problem solving abilities with indicators of understanding the problem by 93% were in the very good category, the indicators of making a completion plan were 73% in the good category, the indicators of implementing the plan were 65% in the good category and the indicators of checking the results were 25 % with less category. After participating in learning using the Indonesian Realistic Mathematics Education Approach (PMRI) the average post-test score was 70.35 with 5 excellent students, 12 good students and 6 good enough students.
