Abstract

Rendahnya pemahaman konsep siswa kelas tiga di sebuah SD Negeri di Sindangkerta pada mata pelajaran Sains merupakan latar belakang penelitian ini. Salah satu upaya yang dapat dilakukan untuk mengatasi masalah ini adalah dengan memanfaatkan media pembelajaran yang menarik dan model pembelajaran berpusat pada siswa. Penelitian ini bertujuan untuk mengembangkan video animasi melalui model Pembelajaran Berbasis Masalah (PBL) dalam meningkatkan pemahaman konseptual siswa. Metode penelitian yang digunakan adalah Penelitian dan Pengembangan (R&D) dengan model Borg dan Gall yang disederhanakan. Subjek penelitian adalah 20 siswa kelas tiga di sebuah SD Negeri di Sindangkerta. Data dikumpulkan melalui observasi, tes pemahaman konsep, kuesioner analisis kebutuhan, dan lembar validasi ahli. Hasil penelitian menunjukkan bahwa respons siswa terhadap media video animasi dalam model pembelajaran berbasis masalah dinilai baik dan sesuai untuk digunakan, hal ini dapat dilihat dari persentase respons siswa pada tes terbatas sebesar 78,12%, dan tes luas sebesar 79,68%. Dengan demikian, serangkaian data penelitian menegaskan bahwa penggunaan media video animasi telah mendapat respons positif dari siswa dan telah memberikan kontribusi signifikan terhadap kedalaman pemahaman konseptual mereka. Diharapkan hasil penelitian ini dapat menjadi pertimbangan bagi siswa dan guru untuk memanfaatkan media yang menarik guna mencapai tujuan pembelajaran.

Abstract

This research aims to find out and analyze the media visual basic for application (VBA) Excel in improving students' reasoning abilities and active learning through learning models problem-based learning. The research method and design used is a quasi-experimental design nonequivalent control group. The subjects in this research were class VIII students at one of the state junior high schools in the West Bandung Regency area. The data collection technique used in this research is data pretest, posttest, and N-Gain mathematical reasoning abilities and student learning activity questionnaires. Then the data is processed using software Microsoft Excel 2020 and IBM SPSS Statistics 26. The research results show that the application of VBA media Excel through learning models problem-based learning can improve students' mathematical reasoning abilities and active learning. One of the findings shows that students have the ability and skills to apply concepts or material through problems that exist in the student environment and are able to complete complex calculations, analyze data, or prepare solution processes through VBA Excel.

Abstract

This study aims to determine the effect of the discovery learning model in improving mathematical problem solving abilities and habit of minds of class VII middle school students. The research method used in this study is quasi experiment. This research was carried out in one of the private junior high school in the city of Cimahi by selecting two classses, namely VII A dan VII B. Each clas has 30 students. The instruments used were 5 questions on problem solving ability and habit of mind. Data in the form of test result and questionnaries were processed using the N-gain test and the difference test between two averages with the help of the SPSS. The result showed that the class whose learning used the discovey learning model had mathematical problem solving ablities and students’ habit of minds better than the class which used ordinary learning.

Abstract

This research aims to determine and analyze students' mathematical reasoning abilities in terms of students' learning motivation (high, medium and low). The research method used is descriptive qualitative, namely a research method that will describe a phenomenon. The subjects in this research were 34 class VIII students at a school in Cimahi City. The instruments used were a mathematical reasoning ability test, a learning motivation questionnaire, and an interview guide. Data from the research results were processed based on student learning motivation in the high, medium and low categories for each indicator of mathematical reasoning ability. Based on the research results, it shows that the average value of mathematical reasoning ability of students with high learning motivation is 64.4%, the average value of mathematical reasoning ability of students with moderate learning motivation is 62%, and the average value of mathematical reasoning ability with motivation low learning by 50%. In general, among students' difficulties in working on mathematical reasoning ability questions are errors in mathematical calculations, this shows that students do not understand the concept and only use their memory to solve the problem.

Abstract

Computational thinking is an important 21st-century skill that students need to learn. This study aims to describe students’ computational thinking abilities in solving mathematical problems, reviewed from the adversity quotient (AQ) types: quitters, campers, and climbers. This research employed a qualitative approach based on a case study with the perspective of grounded theory. Six eighth-grade students from a public junior high school in Cimahi were chosen, with two students selected for each AQ type. Data were collected through two steps which are tests and interviews, then analyzed using NVivo 14 (trial version). Computational thinking skills were analyzed based on eight categories: (1) problem identification, (2) formulation of a mathematical representation, (3) recognition of regularities, (4) determination of the pattern, (5) analysis of key characteristics, (6) formulation of alternative solutions, (7) develop the solution steps, and (8) draw a conclusion. The results showed that quitters demonstrated categories 1, 2, 3, 7, and 8; campers fulfilled categories 1, 2, 3, 5, 6, and 7; and climbers achieved categories 1, 2, 3, 4, 5, 6, and 7. These differences were influenced by the distinct characteristics of each AQ type. AQ could become the basis to design adaptive learning strategies to enhance students’ computational thinking abilities.
