Abstract

Abstrak Penelitian ini bertujuan untuk mengetahui perbedaan hasil belajar matematika siswa antara model pembelajaran kooperatif tipe group investigation dengan pembelajaran konvensional materi segiempat dan segitiga di kelas VII SMP Negeri 18 Kota Bengkulu. Penelitian ini merupakan penelitian eksperimen semu. Sampel penelitian ini adalah siswa kelas VII.5 sebagai kelas eksperimen yang berjumlah 31 peserta didik yang mendapat perlakuan model pembelajaran kooperatif tipe group investigation dan kelas VII.1 sebagai kelas kontrol yang berjumlah 29 peserta didik yang mendapat perlakuan pembelajaran konvensional. Teknik pengumpulan data berdasarkan posttest. Pada pengujian persyaratan analisis diperoleh bahwa kedua data berdistribusi normal namun kedua data tidak homogen. Pengujian hipotesis menggunakan SPSS diperoleh nilai signifikan = 0,000 <  = 0,05 maka  ditolak. Oleh karena itu, dapat  disimpulkan bahwa terdapat perbedaan  yang signifikan pada rata-rata hasil belajar matematika siswa antara model pembelajaran kooperatif tipe group investigation dengan pembelajaran konvensional pada materi segiempat dan segitiga di kelas VII SMP Negeri 18 Kota Bengkulu.  Abstract This study aims to determine differences in student study results of mathematics between cooperative learning model group investigation type with conventional learning material quadrilateral and triangle in class VII of Junior High School 18 Bengkulu City. This research was a quasi-experimental research. The sample of this study was the students of class VII.5 as the experimental class of 31 learners who received treatment model of cooperative learning type group investigation and class VII.1 as the control class which amounted to 29 students who received the conventional learning treatment. Data collection technique based on posttest. In the analysis requirements test obtained that the two data were normally distributed but the two data were not homogeneous. Hypothesis test used SPSS obtained significant value = 0,000 < ? = 0.05 then  was rejected. Therefore, it can be concluded that there was a significant difference in the average of students' mathematics study results between cooperative learning model of group investigation type with conventional learning on rectangular and triangle material in class VII of Junior High School 18 Bengkulu City.

Abstract

Kemampuan penalaran matematis di masa pandemi Covid-19 masih rendah. Penelitian ini bertujuan mengetahui pengaruh mathematical disposition dan self-concept terhadap kemampuan penalaran matematis mahasiswa. Penelitian ini menggunakan pendekatan kuantitatif ex-post facto. Sampel penelitian berjumlah 83 mahasiswa S1 Pendidikan Matematika di Kota Bengkulu. Instrumen penelitian ini terdiri dari angket mathematical disposition, angket self-concept dan tes kemampuan penalaran matematis. Data dianalisis dengan teknik analisis regresi. Hasil penelitian menunjukkan bahwa terdapat pengaruh langsung dari mathematical disposition terhadap kemampuan penalaran matematis. self-concept terhadap kemampuan penalaran matematis, dan mathematical disposition terhadap self-concept. Selain itu, terdapat juga pengaruh mathematical disposition dan self-concept secara bersama-sama terhadap kemampuan penalaran matematis. Disimpulkan bahwa terdapat pengaruh mathematical disposition dan self-concept terhadap kemampuan penalaran matematis mahasiswa S1 Pendidikan Matematika di Kota Bengkulu pada masa pandemi Covid-19. Mathematical reasoning ability during the Covid-19 pandemic is still low. This study aims to determine the effect of mathematical disposition and self-concept on students' mathematical reasoning abilities. This study uses an ex-post facto quantitative approach. The Sample of this research was 83 students of S1 Mathematics Education in Bengkulu City. The research instrument consisted of a mathematical disposition questionnaire, a self-concept questionnaire, and a mathematical reasoning ability test. Data were analyzed by regression analysis technique. The results showed there was a direct influence of mathematical disposition on mathematical reasoning abilities, self-concept to mathematical reasoning ability, and mathematical disposition to self-concept. In addition, there is also the effect of mathematical disposition and self-concept together on mathematical reasoning abilities. It was concluded that there was an influence of mathematical disposition and self-concept on the mathematical reasoning ability of S1 Mathematics Education students in Bengkulu City during the COVID-19 pandemic.
