Abstract

This study aims to measure the level of validity, practicality and effectiveness of Problem Based Learning social arithmetic teaching materials assisted by Liveworksheets. This study uses the Research and Development (R&D) method of Sugiyono's development model which consists of 10 stages which are limited to step 7, namely: potential and problems, data collection, product design, design validation, design revision, product trial, and product revision. The research subjects were: a VII grade math teacher, 10 VIII grade students, and 30 VII grade students. Instruments in this study include: interview sheets, validation sheets, student response questionnaires, and mathematical communication skills tests. Data processing techniques in the form of quantitative data analysis include validity analysis, practicality analysis, and effectiveness analysis of test results. The results of this study that LKPD teaching materials have met the eligibility criteria. This is because based on the results of the validation of experts who get a score of 80% which is considered valid. In the limited product trial, a score of 81% was obtained in the very practical category. As well as extensive product trials obtained a score of 85% with a very practical category. Then during the effectiveness test, it got a score of 80% with the effective category. Thus teaching materials in the form of learner worksheet are suitable for use in the learning process.

Abstract

This study aims to evaluate the extent to which students understanding of mathemmatical concepts improves when thaught using the problem based learning model compared to those taught using the conventional model, discovery learning. The research employs an experimental method with a quasi eksperimental design, dividing students into two groups: an experimental class and a control class. The study’s populasi includes all eight grade students at SMP Terpadu Al Mumin. Data Collection was carried out using to measure student’s understanding of mathematical concepts. The collected data were then processed using IBM SPSS 26, with data analysis encompassing normality tests, homogenity tests, and independent two sample t-test. The results indicate that students taught using the problem based learning model show more effective mathematical conceptual understanding compared to those taught using the conventional learning model. Additionally, there was a significant improvement in the understanding of mathematical concepts among students exposed to the problem based learning model compared to those using the conventional teaching method.

Abstract

This research is to find out whether the mathematical connection abilities of students who use the Contextual Teaching and Learning approach assisted by the Scratch application are better than students who use ordinary learning, a scientific approach. This type of research is quantitative research with a quasi-experimental design in the form of Pretest Posttest Nonequivalent Control. Class VIII students of SMP Negeri 4 Cimahi were the subjects of this research. Class VIII-K is the sample for the experimental class and class VIII-L is the control class. The test instrument used is 4 questions on mathematical connection abilities. The data analysis techniques in this research are normality test, homogeneity test and independent two-sample t-test. The research results show that the mathematical connection abilities of students who use the Contextual Teaching And Learning learning model are better than students who use the normal approach. The average ability of students is moderate because students do not focus on studying and steal time during learning for other activities.

Abstract

The background of this research was that nowadays high school students are required to have a significant understanding and appreciation of mathematics. The fact was that students experience difficulties in learning mathematics, including their mathematical literacy and numeracy abilities. The aim of this study was to investigate the significance of the effect of the PBL learning model using TPACK on students' mathematical literacy and numeracy abilities; The method used in this research was quasi-experimental. The statistical analysis tool used was the MANOVA test which is used to analyze two dependent variables (mathematical literacy and numeracy abilities) simultaneously. Then used the t-test of two independent and dependent samples. The research sample was class XI at one of the public high schools in the city of Bandung, consisting of 2 classes. The results showed that the achievement and improvement of mathematical literacy and numeracy abilities jointly owned by students in the two learning groups showed a significant difference. The conclusions obtained in this study were: (1)there were differences in achievement and improvement in mathematical literacy and numeracy abilities simultaneously between students who received the PBL learning model using TPACK and a scientific approach; (2)there was no difference in increasing mathematical literacy abilities between students who get the PBL learning model using TPACK and scientific; (3)there was a difference in increasing mathematical numeracy abilities between students who get the PBL learning model using TPACK and scientific.
