Abstract

Kemampuan Pemecahan Masalah Matematis (KPMM) adalah keterampilan esensial yang perlu dimiliki dan dikuasai siswa, terutama dalam menyelesaikan masalah sehari-hari namun realitas di lapangan menunjukkan kemampuan memecahkan masalah masih rendah. Dalam mendukung peningkatan KPMM, maka diperlukan bahan ajar yang membantu siswa untuk belajar secara aktif dan tidak menimbulkan perasaan bosan pada diri siswa ketika siswa mempelajari matematika di sekolah. Tujuan penelitian ini  mengembangkan bahan ajar menggunakan pendekatan berbasis masalah berbantuan geogebra. Design Research adalah metode yang dipergunakan pada  penelitian ini. Penelitian ini terbagi menjadi dua bagian, yaitu desain perencanaan dan desain evaluasi formatif. Subjek pada penelitian adalah  38 siswa SMK  Gema Karya Bahana di Kota Bekasi Kelas X.  Alat yang digunakan dalam pengumpulan data berupa  skala sikap, wawancara, dokumentasi dan uji coba soal. Pengolahan data menggunakan cara kuantitatif dan kualitatif. Kesimpulan pada penelitian ini adalah  bahan ajar menggunakan pendekatan berbasis masalah berbantuan geogebra sangat valid, praktis dan sangat efektif dalam meningkatkan KPMM terutama dalam materi Program Linear, sehingga bahan ajar menggunakan pendekatan berbasis masalah berbantuan geogebra dapat dipergunakan sebagai alternatif  dalam meningkatkan KPMM siswa

Abstract

Procrastination is often experienced by teenagers. Procrastination in adolescents is caused by several factors such as wasting time, avoiding tasks, and blaming others. This study aims to determine the effectiveness of the module on academic procrastination of class XI students of SMAN 1 Saguling. The subjects in this study were 30 students of class XI and were selected based on the recommendation of the guidance and counseling teacher on the consideration of the highest level of students experiencing procrastination. Data analysis used normality test and t test. The trial process for the handbook based guidance and counseling module was carried out by distributing pretest and posttest questionnaires, calculating the effectiveness using SPSS and carried out 2 times, namely normality test and T-test on pretest and protest during the trial. The results of the normality test showed the significance value of the pretest was 0.111 and the posttest was 0.008 so that the normality test can be said to be normally distributed. The results of the t-test showed a 2-tailed significance value of 0.000 so that in this t-test there was a difference between the pretest and posttest variables because they had a 2-tailed significance value 0.05. So that the results of the t-test carried out can be seen that the developed module is proven to be effective on academic procrastination of class XI students of SMAN 1 Saguling.

Abstract

The purpose of this study is to analyse the students’ cognitive ability in the terms of reasoning which are relation to numbers and orders, and the application of learning that has not developed yet as what the teachers hope. This research is aimed to see how the early childhood can develop their cognitive ability by using picture card game. The type of this research is classroom action research (CAR) that has been done in three cycles. The subject of this research is early childhood as many as 16 students consisting of 8 male students and also 8 female students that age 4 to 5 years old. The researcher used observation, interview, and questionnaires as the instruments for data collection techniques. Then, the researcher analysed the data using qualitative method and it was also completed with quantitative analysis called as descriptive statistical analysis through percentage count. The finding of this research is there is a significant development of children’s cognitive ability in the terms of reasoning and numeracy ability. The development of early childhood skill in every cycle becomes an indicator where the result of pre-cycle to the children in development stage is 31, 25%. In the first cycle, it developed into 37, 5%, the second cycle increased into 43, 75%, and for the third cycle it became 56, 25%. The result of those all activities are that the application of picture card game can develop cognitive ability to early childhood. The use of picture card media will be much better if it is implemented with a various variety of game.

Abstract

The purpose of this study was to improve students mathematical literacy skills in statistics by appliying the Contextual Teaching and Learning (CTL) approach. Students of SMP Negeri 2 Padalarang became the population in this study. Thirty students of class VIII-A served as the experimental group and thirty students of class VIII-I served as the control group. This study used a non-equivalent control group design with quasi-experimental research methodology. This study included pretest, action, and posttest. This research tool used a written test to collect information about the improvement of students’ mathematical literacy skills. Data analysis was carried out by conducting normality test, homogeneity test and mean test in order to obtain conclusions. The findings of this study show that the improvement of mathematical literacy skills of students whose learning uses the Contextual Teaching and Learning (CTL) approach is better the those who use ordinary learning.

Abstract

Mathematical connection ability is one of the high level abilities but is still classified as low because students' understanding of the conceptual material given by the teacher, there are still students going through steps in working on the problems given, such as describing a symbol, in completing mathematical concepts, therefore This research aims to examine the effectiveness of using the Missouri Mathematics Project Learning Model carried out at MTs Ibnu Sina Jl. Tegal Overtime No. 105, Pamekaran, District. Soreang, Bandung Regency, West Java 4091, by taking a sample of 60 students consisting of control and experimental classes. The research method used in this action was the experimental method. Based on the results of descriptive analysis of students' mathematical ability data before being given treatment, it showed the highest score was 70, the lowest score was 55 and the average score was 61. Meanwhile, the results of descriptive analysis of students' mathematical ability data after being given The treatment showed the highest score of 70, the lowest score of 55 and the average score of 61. Those given the treatment showed the highest score of 87, the lowest score of 69, and the average score of 77.83. So the average mathematical connection ability of students after being given treatment is higher than the students' mathematical ability before being given treatment.

Abstract

The purpose of this study is to combine the RME approach with the use of the CapCut application in an effort to optimize students' mathematical problem-solving skills. Realistic Mathematics Education is an approach that uses the real world to understand and solve problems. The population in this study of students at SMPN 1 Cihampelas the sample used is class VIII students with a total of 40 students. The learning instruments and tools used are Pretest and Postes questions and LKPD which contain material about the Pythagorean theorem and the characteristics of the Realistic Mathematics Education approach. The results of the Mann-Whitney test analysis prove that the improvement of mathematical problem-solving skills of grade VIII students whose learning uses the Realistic Mathematics Education approach assisted by CapCut learning videos is better than students who use regular learning. So that the RME and CapCut approaches are able to optimize students' mathematical problem-solving skills.
