Abstract

Penelitian ini bertujuan untuk menelaah perbedaan disposisi matematis siswa yang memperoleh pembelajaran dengan pendekatan matematika realistik dan siswa yang memperoleh pembelajaran dengan pendekatan konvensional.Dalam penelitian ini metode yang digunakan adalah metode kuantitatif yaitu Quasi Experimental Design dengan bentuk postresponse only, nonequivalent control group design. Penelitian ini dilaksanakan disalah satu SMP Negeri di Lembang Jawa Barat. Data diperoleh dari non-tes berupa angket skala disposisi matematis. Hasil penelitian menunjukkan bahwa, disposisimatematis siswa yang memperoleh pembelajaran dengan pendekatan matematika realistik lebih tinggi secara signifikan daripada siswa yang memperoleh pembelajaran dengan pendekatan konvensional.

Abstract

Latar belakang penelitian ini adalah kesulitan belajar siswa dalam menyelesaikan masalah geometri dimensi tiga. Tujuan dari penelitian ini adalah mendeskripsikan dan menggambarkan antisipasi eksploratif siswa dalam menyelesaikan soal geometri dimensi tiga. Penelitian ini menggunakan metode tes dan wawancara. Tes tulis dengan soal geometri dimensi tiga berbentuk kubus. Wawancara dilakukan kepada siswa dengan kategori antisipasi eksploratif. Hasil dari penelitian ini adalah (1) Siswa membaca soal lebih dari satu kali, (2) Siswa menemukan hal yang ditanyakan dan hal yang diketahui, (3) Siswa menguraikan soal secara rinci, (4) Siswa menghubungkan kriteria-kriteria yang diketahui, dan (5) Siswa memecahkan soal dengan mempertimbangkan alternatif penyelesaian.

Abstract

This study aims to assess the performance of teachers in applying all competencies in the learning process, mentoring in school education and planning for continuous professional development for teachers. Where in the process of assessing teacher performance at the school, they still use manual applications with a simple addition method and the lack of speed in processing teacher performance assessments is increasing from year to year. To solve these problems, the Weighted Product method was chosen, this method helps teacher performance appraisal decisions so that they get the best results, then implements the method into an application decision support system to speed up the assessment process. Then the final result of this study with a calculation accuracy rate of 100% based on manual calculations and calculations on the application with the results agreeing to the decision support system made.

Abstract

The purpose of this study is to determine the effect of the TGT (Teams Games Tournament) learning model on statistics material for class VII junior high school on mathematical problem solving abilities. This research was a quantitative research using Quasi Experimental Design. The sampling technique in this study used purposive sampling. Class VII D, consisted of 24 students as the experimental class and class VII C consisted 24 students as the control class. The instruments used in this research were Pretest-Posttest with 3 questions. The data analysis techniques used in processing the data were analysis prerequisite tests (normality test and homogeneity test), hypothesis testing, and the N-Gain test. Based on the results of calculations that have been carried out, the posttest average value for the experimental class was 92, while the posttest average value for the control class was 85. In addition, based on the data obtained from the results of the hypothesis testing, it results that the  value is 0.000 then Ho  is rejected and Ha is accepted. This is in line with the average N-Gain value in the experimental class resulting in 0.82 high criteria, while the average N-Gain value in the control class produces 0.66 medium criteria. So it can be concluded that there is an influence of the TGT (Teams Games Tournament) learning model on students' mathematical problem solving abilities.
