ALGEBRAIC THINKING ABILITY AND LEARNING INTEREST THROUGH SOCIAL MEDIA-BASED PICTORIAL PUZZLE IN NEW NORMAL ERA

Algebraic ability is one of the most important abilities to be developed because it becomes the basis to achieve other mathematical thinking ability. In new normal era, information through social media is the main thing for society, particularly for children of the current generation. This study aims to describe algebraic thinking ability and students' interest in learning through social media-based pictorial puzzles. The method of the research is descriptive quantitative. The samples of this study were 6 students of grade VIII SMP Edu Global School in Cirebon city. This study indicates that algebraic thinking ability and students' interest in learning algebra are still classified as moderate and have not reached the high category, so it needs to be improved in the learning process

PENINGKATAN KEMAMPUAN PENALARAN DAN KOMUNIKASI MATEMATIS SERTA MOTIVASI BELAJAR SISWA SMP MELALUI PENERAPAN METODE DISCOVERY LEARNING : Kuasi Eksperimen Pada Siswa SMP Di Kota Cirebon

Penelitian ini bertujuan untuk mengkaji masalah peningkatan kemampuan penalaran dan komunikasi matematis siswa sebelum dan setelah memperoleh pembelajaran dengan metode discovery learning dan konvensional, serta menelaah motivasi belajar matematika siswa setelah dilakukan proses pembelajaran. Penelitian ini menggunakan pendekatan kuantitatif dengan metode kuasi eksperimen dengan desain nonequivalent control group design. Dalam rancangan desain ini, sampel yang digunakan terdiri dari dua kelompok, yaitu kelompok eksperimen (yang diberi perlakuan) dan kelompok kontrol (pembelajaran konvensional) dan tidak dipilih secara random. Subyek penelitian terdiri dari 40 siswa kelas eksperimen dan 41 siswa kelas kontro yang dipilih secara purposive dari salah satu SMP Negeri di Kota Cirebon. Analisis data penelitian dilakukan secara kuantitatif berdasarkan keseluruhan sampel maupun dirinci berdasarkan kategori kemampuan matematis awal (KMA): tinggi, sedang, dan rendah. Hasil penelitian menunjukkan bahwa peningkatan kemampuan penalaran dan komunikasi matematis siswa yang memperoleh metode discovery learning lebih tinggi secara signifikan baik secara keseluruhan atau berdasarkan KMA dibandingkan siswa yang memperoleh pembelajaran konvensional. Kemudian motivasi belajar matematika siswa yang memperoleh metode discovery learning lebih baik secara signifikan baik keseluruhan atau berdasarkan KMA tinggi dan rendah, tetapi tidak lebih baik untuk KMA sedang.----------This study is aimed to study the problem of mathematical reasoning and communication ability enhancement before and after getting learning with discovery learning method and conventional methods, and to exemine students' motivation in learning mathematics after learning process was done. This study used quantitative approach with quasi experiment method with nonequivalent control group design. In this experiment design, sample used consisted of two groups, namely experiment group (which was given treatment) and control group (conventional learning) and was not selected randomly. Subject of study consisted of 40 students of experiment class and 41 students of control class who were selected purposely from one of Public Junior High School in Cirebon City. Data analysis was done quantitatively based on whole samples and was detailed based on the category of mathematical initial ability (MIA): high, medium, and low. The study result showed that the enhancement of mathematical reasoning and communication ability of students who get discovery learning method was higher significantly either in a whole or based on MIA compared to students who get conventional learning. Then learning motivation of students who get discovery learning method is better significantly either in a whole or based on high and low MIA, but is was not better for medium MIA

Analisis Kemampuan Koneksi Matematis Siswa SMK pada Materi Matriks ditinjau dari Self Efficacy

Mathematical connection ability is one of the important skills in learning mathematics. When students are able to relate mathematical ideas, their understanding of mathematics deepens and lasts longer. Based on the data in the field, it was found that students were still unable to recognize and relate mathematical ideas. During mathematics learning, behaviors that lead to math anxiety and lack of self-confidence were also found. The purpose of this study is to analyze students' mathematical connection abilities in terms of self-efficacy and mathematics anxiety. This type of research is a descriptive qualitative research using mathematical connection test aids, self-efficacy questionnaires, and mathematics anxiety questionnaires to collect data. The subjects in this study were 6 students of SMK majoring in TBSM. The results showed that students who have high, medium, and low self-efficacy can meet 3 indicators of mathematical connection ability

Profil Kemampuan Berpikir Aljabar Siswa SMP pada Materi Volume Kubus

The purpose of this study is to describe the students’ algebraic thinking skills and errors in solving algebraic problems on volume of cube material for class VIII of Junior High School. The research design used was in a form of the descriptive qualitative research method. This study captured the students’ algebraic thinking skill on two indicators, namely the students’ ability to represent problems in the relationship between variables and the students’ ability to perform operations on algebraic form. Based on the result of the categorization, three students from the high-level category were chosen as the subjects of this study. In depth interviews were given to the subjects of the study in order to explore the answers that they provide on the mathematic problems given. The findings revealed that the students with high-level of algebraic thinking skills could solve mathematics problem in algebraic form correctly especially in transformational activities. It was indicated by the students’ ability to provide a solution for algebraic equation problems. Meanwhile, the students’ error in solving the mathematical problems in a form of build-cube space was due to the students’ inaccuracy in writing the final results on the answer sheets for the algebraic thinking ability test. Overall, the students encountered several types of errors, those were the error in the procedural and technical/calculated on comparisons, the error in witing mathematical units, and lastly the error in substituting variable

Psychosocial Development of Children Addicted Versus Not Addicted to Smartphones

Psychosocial development of preschool children is the process of children’s abilities developing and children starting to take the initiative to solve their own problems according to their knowledge. However, many preschool children are currently addicted to gadgets such as smartphones, which can interfere with their taking initiative and paying attention to the social environment. The aim of this study was to determine the differences in psychosocial development between children who are addicted vs. those who are not addicted to smartphones in preschool age children. This study was a descriptive comparative study and it used a simple random sampling technique to select the respondents. The Mann-Whitney test was employed to analyze the data with a significance degree of 0.05 (5%). The results showed that there was a significant difference between addicted and non-addicted children. In the non-addicted group of children, the median value was 2.00 (1.61-1.78) and in the addicted group of children the median value obtained was 1.00 (1.03-1.11). The average ranking for the non-addicted group was 52.50 and was 28.50 for the addicted group. It is recommended that parents understand the impact of using gadgets such as smartphones on children’s psychosocial development, and that parents pay more attention to each phase of children’s development, especially psychosocial development at preschool age.
