Abstract

The aim of this research is to determine the differences in student learning outcomes taught using the realistic mathematics approach (PMR) assisted by Obibul teaching aids and the learning outcomes of students taught using the direct learning model. The research method used is the experimental method, with a design namely pretest-posttest control group design. Sampling used a random sampling technique from 3 classes, namely classes VII.A, VII.B and VII.C, two classes were selected as samples with a total of 25 students as respondents for each class. Based on the results of the lottery drawing, class VII.B was selected as the experimental class which used a realistic mathematics approach (PMR) assisted by Obibul teaching aids while class VII.A was selected as the control class which used a direct learning model. The instrument used for research is in the form of a description/essay. Hypothesis testing uses the ANCOVA test which produces Fcount = 5.73, which is compared with the value of ????table = 3.94 so that ????0 is rejected. The results of this research concluded that there were differences in the learning outcomes of students who were taught using the realistic mathematics approach (PMR) assisted by Obibul teaching aids and the learning outcomes of students who were taught using the direct learning model.

Abstract

Penelitian ini membahas tentang pengembangan instrumen kemampuan penalaran matematis, dimana bertujuan menghasilkan instrumen untuk mengukur kemampuan penalaran matematis pada peserta didik yang memiliki kualitas kategori baik yang sudah diuji berdasarkan uji kevalidan, reliabilitas, tingkat kesukaran serta daya pembeda. Dengan jenis penelitian yang digunakan yaitu penelitian “formative research tessmer and development“ dimana terdiri atas; tahap preliminary, tahap self evaluation, tahap formative evaluation (prototyping) yang meliputi expert riviews, one-to-one, dan small group, serta field test (uji coba lapangan). Berdasarkan hasil yang didapat menunjukan jika instrumen yang dihasilkan sudah “valid” karena memiliki nilai CVR dan CVI dengan nilai 1 dengan reliabilitas tergolong reliabel dengan nilai 0,68. Hasil rata-rata tingkat kesukaran 0,52 dengan kategori sedang. Hasil rata-rata daya pembeda adalah sebesar 0,38 dengan kategori baik. Serta rata-rata kemampuan penalaran matematis peserta didik sebesar 33,61 dengan kategori cukup. Berdasarkan analisis data, dari 85 peserta didik ubjek uji coba terdapat 6 peserta didik (7,06%) yang memiliki kemampuan penalaran matematis sangat baik, 28 peserta didik (32,94%) yang memiliki kemampuan penalaran matematis baik, 36 peserta didik (42,35%) yang memiliki kemampuan penalaran matematis cukup, 14 peserta didik (16,47%) yang memiliki kemampuan penalaran matematis kurang, serta 1 peserta didik (1,18%) yang memiliki kemampuan penalaran matematis sangat kurang. Sehingga masih sangat dibutuhkan usaha lebih lanjut guru agar bisa memberikan tes-tes yang dapat memacu kemampuan penalaran matematis.

Abstract

This study aims to determine the effect of the problem-based learning model on students' mathematical problem-solving abilities in the social arithmetic materialThis study is an experimental study with a post-test only control group design. The sample in this study was class VII-A and VII-B at MTs Negeri 2 Kab. Gorontalo with a simple random sampling technique. The research instrument used was a problem-solving ability test on the Social Arithmetic material. The results of the study showed that there was an effect of problem-based learning on students' mathematical problem-solving abilities in the social arithmetic material, where the hypothesis testing using the t-test obtained a t-count value > t-table, namely 10.73 > 1.69. So it can be concluded that learning mathematics on the subject of social arithmetic using the problem-based learning model has a significant effect on improving students' mathematical problem-solving abilities compared to those using direct learning. So from what has been obtained, teachers can use the problem-based learning model as an effort to improve students' mathematical problem-solving abilities.

Abstract

This study aims to investigate the influence of electronic worksheets based on live worksheets on student learning outcomes in the material of systems of linear inequalities with two variables. This research is an experimental study with research subjects classified into two groups: X-Gusdur class as the experimental group and X-ir. Soekarno, as the control group with the population, is SMA Negeri 1 Momunu, using a pre-test and post-test control group research design. Data collection techniques were test instruments based on indicators after the learning process. Pre-tests and post-tests were used to measure student learning outcomes. Data processing used descriptive analysis, showing that the average student learning outcomes in the experimental class were higher than in the control class. The results of the inferential analysis showed that both data were normally distributed and homogeneous; thus, the covariance analysis (ANACOVA) was continued, and results were obtained where Ho was rejected and H₁ was confirmed.From the descriptive analysis, it can be seen that the average learning outcome score in the experimental group was 79.96, which was significantly higher than the average score in the control group, which only reached 69.19. Likewise, the results of hypothesis testing using the ANACOVA test also showed more favorable results for the experimental group with 𝛼 = 0.05 obtained by FcountFtable (12.024.04). Therefore, the research findings in heate that student learning outcomes are higher after being taught using ce on live worksheets than printed worksheets.
