Abstract

Hasil dari tes NAEP secara konsisten telah menunjukkan bahwa peserta didik memiliki pemahaman yang sangat lemah terhadap konsep pecahan. Salah satu penyebabnya adalah rendahnya keterampilan komunikasi matematis peserta didik dan kurangnya tanggung jawab peserta didik untuk belajar. Oleh karena itu diperlukan suatu pendekatan pembelajaran yang tepat untuk mengatasi permasalahan tersebut. Salah satu pendekatan pembelajaran yang dapat digunakan adalah dengan menggunakan pendekatan PMRI berbantuan scaffolding. Tujuan penelitian ini adalah mendeskripsikan karakter tanggung jawab dan keterampilan komunikasi matematis peserta didik serta menguji keefektifan penerapan pembelajaran dengan pendekatan PMRI berbantuan scaffolding pada materi pecahan dalam meningkatkan kemampuan komunikasi matematis. Penelitian ini merupakan penelitian kombinasi (mixed methods) model concurrent embedded dengan metode kualitatif sebagai metode primer. Subjek penelitian dipilih dengan teknik purposive sehingga terpilih lima peserta didik yang menempati ranking pertama, kuartil satu, kuartil dua, kuartil tiga, dan ranking terakhir. Hasil penelitian menunjukkan bahwa secara keseluruhan setelah dilakukan pemberian dorongan (scaffolding) selama pembelajaran PMRI berlangung, karakter tanggung jawab dan keterampilan komunikasi matematis kelima subjek penelitian mengalami peningkatan. Dengan meningkatnya tanggung jawab peserta didik untuk belajar dan kemampuan mereka dalam mengkomunikasikan ide matematika maka kemampuan komunikasi matematis peserta didik juga meningkat. The results of NAEP tests have consistently shown that learners have a very weak understanding of the fractions concept. One reason is the lack of mathematical communication skills of the students and the lack of responsibility of learners to learn. There fore we need an approach of learning that appropriate to solve these problems. One of the approach of learning by using scaffolding assisted PMRI approach. The purpose of this study is to describe the character of the responsibilities and mathematical communication skills of learners and to check the effectiveness of the application of learning to approach the scaffolding material PMRI aided fractions to improve communication skills in mathematic. This research is mixed methods concurrent embedded models with qualitative methods as the primary method. Subject of the research is selected by purposive technique that was selected five students who ranked first, quartile one, quartiles two, three quartiles, and the final ranking. The results showed that overall after giving encouragement (scaffolding) during PMRI learning in progress, the character of the responsibilities and skills of mathematical communication of fifth research subjects have increased. By increasing of responsibilities of the learners to learn and their ability to communicate the mathematical ideas so the mathematical communication ability of the students also increased.

Abstract

This study aims to determine the mastery of reasoning ability and mathematical communication, the difference of reasoning ability and mathematical communication in the two sample classes, and also describes the students' reasoning and communication ability. Type of research used is mix method. Quantitative research with random sampling technique while qualitative research with purposive technique. Data collection uses observation, tests, questionnaires, and interviews. The learning mastery test shows that the reasoning ability and the mathematical communication of the experimental class learners reaches completeness. The average difference test shows that the reasoning ability and the experimental mathematics of the experimental class is better than the control class. Based on the learning style not all students who have good reasoning ability, the communication skills are good, and vice versa. This research is expected to be useful to be a source of information in answering the problems that occur in the learning process, especially in improving student learning outcomes in sub rectangular themes.

Abstract

Mathematics learning is very important given in order to the students can have problem solving skills. This study aims to test the effectiveness of PBL assisted by the web on students' problem solving abilities and describe problem solving abilities in terms of student independence. This research is a type of quantitative and qualitative. The study was conducted in Bangsri 1 Public High School SMA Negeri 1 Bangsri in the 2018/2019 academic year. The research subjects were tenth grade students consisting of one experimental class with web-based PBL treatment and one control class. Then two people were selected for the category of high, medium and low independence. Hypothesis testing uses one-party t-test and average difference test. The results of the study showed that PBL was assisted by the web effective against students' problem solving abilities. Students with high independence criteria do not always have good problem solving skills, but they show a significant increase after working on practice questions. Students with moderate independence criteria also showed an increase in problem solving skills after working on practice questions. Whereas in the low independence criteria there are students with good cognitive abilities but the problem solving ability improvement is low.

Abstract

This study aimed to describe the quality of PBL learning assisted by monopoly games on students 'critical thinking skill, and describing students' critical thinking skills through PBL learning assisted by monopoly game in terms of self-confidence. This study used mixed methods with concurrent embedded designs. The research subjects were seventh grade students of SMP N 18 Semarang. The results of this study showed that implementation PBL assisted by monopoly game improve the students’ mathematical critical thinking skills. In the aspect of the process of mathematical critical thinking skills, students with high self-confidence are able to master the five aspects very well. The five indicators of critical thinking are elementary clarification skills, basic skills building skills, inference skills, advanced clarification skills, and strategies and techniques. Students with medium self-confidence, mastering four aspects maximally, those are skills to give simple explanations, inference skills, advanced clarification skills, and strategies and techniques. Meanwhile, students with low self-confidence, only able to master one aspect well but not maximally that is ability to give a simple explanation (elementary clarification).

Abstract

Mathematics learning is very important given in order to the students can have problem-solving abilities. This study aims to test the effectiveness of cooperative problem solving (CoPS) learning assisted by the GeoGebra 3D on students' problem-solving abilities and describe problem solving abilities in terms of students' GeoGebra 3D usage. This research is a type of quantitative and qualitative. The study was conducted in a junior high school named SMP Islam Al Azhar 14 Semarang in the 2018/2019 academic year. The research subjects were eighth grade students consisting of one experimental class with cooperative problem solving learning assisted by GeoGebra 3D treatment and one control class. Then two students were selected for each of the high, medium, and low GeoGebra 3D usage categories. Hypothesis testing uses one-party proportion test and average difference test. The results of the study showed that cooperative problem solving (CoPS) learning assisted by GeoGebra 3D was effective on students' problem-solving abilities. Students with medium and high usage categories of GeoGebra 3D can reach all indicators of problem-solving even though several indicators of problem-solving are achieved with insignificant errors. Students with medium and high GeoGebra 3D usage categories can implement the steps of problem-solving according to Polya's steps, even they are as good at the carry out the plan step. Students with low GeoGebra 3D usage category cannot carry out the Polya's steps well. Students with low GeoGebra 3D usage category faced difficulties to devise problem-solving plan, carry out problem-solving plan, and looking-back step is not done.
