Abstract

This study aims to develop the worksheet based Learning Model Missouri Mathematics Project using Think Talk Write Strategy on cube and cuboid material, and to find out the quality of the worksheet developed in terms of validity and practicality. Subjects in this study are students of class VIII SMP N 11 Lubuklinggau in the even semester of the 2018/2019 school year. This research is a development research that refers to the 4-D development model (Define, Design, Develop, and Disseminate). Based on the analysis results, it was found that the quality of worksheets developed was based on the assessment of 3 validators, the validity aspect was in the Good category with an average score of 3.99, while the quality of worksheets from the practical aspect was in the Very Practical category with an average score of 0.903.

Abstract

ABSTRAK Penelitian ini betujuan untuk mengetahui pengaruh model Missouri Mathematics Project (MMP) pada kemampuan pemahaman dan pemecahan masalah matematika siswa, serta mengetahui hubungan antara kemampuan pemahaman dan pemecahan masalah matematika siswa SMA N 1 Lubuklinggau. Desain penelitian ini adalah randomized pretest-postest control group design. Instrumen yang digunakan adalah tes kemampuan pemahaman dan tes  kemampuan pemecahan masalah matematika siswa. Analisis dilakukan secara kuantitatif. Hasil penelitian menunjukkan bahwa (1) Model MMP tidak berpengaruh secara signifikan terhadap kemampuan pemahaman matematika siswa; (2) Model MMP berpengaruh secara signifikan terhadap kemampuan pemecahan masalah matematika siswa; (3) Terdapat hubungan/keterkaitan antara kemampuan pemhaman dan pemecahan masalah matematika siswa. Kata Kunci    :   Model Missouri Mathematics Project, pemahaman, pemecahan masalah matematika  ABSTRACTThis study aims to determine the effect models Missouri Mathematics Project (MMP) the ability of understanding and solving mathematical problems of students, and to know the relationship between the ability of understanding and solving mathematical problems students SMA N 1 Lubuklinggau. The study design was a randomized pretest-posttest control group design. The instrument used was the test the ability of comprehension and test students' mathematical problem solving ability. Analyses were performed quantitatively. The results showed that (1) Model MMP does not significantly affect the ability of students' understanding of mathematics; (2) Model MMP significantly affect students' mathematical problem solving abilities; (3) There is a relationship / linkages between pemhaman ability and problem solving math students. Keywords:        Model Missouri Mathematics Project, comprehension, mathematical problem solving

Abstract

The objective of this research was to find out the effectiveness of mathematical learning outcomes to the eighth-grade students after giving treatment by using the problem-based learning model. a pre-experimental method was used in this research. The population of this research was all eighth-grade students of Junior High School. The number of the population was 103 students, while the sample was chosen randomly. The sample of this research was 33 students. Data collection was carried out using a test in the form of an essay. The results of this research showed that it was significantly effective to use problem-based learning model in ELPSA framework to the eighth-grade students of Junior High School. It was proved by the average score of the final test after giving treatment was 79.33 and the total number of students who completed the score was 78.79%.
