Abstract

This study aims to determine: the process of developing LKPD, the feasibility of the developed LKPD, the effectiveness of the LKPD and the constraints encountered when developing LKPD using the Contextual approach. The method used is research and development which is modified from the R&D research and development model through the 4D stages (Define, Design, Develop, Dessiminate). This research was conducted at Bina Mulia Mandiri Middle School with research subjects in limited trials, namely 15 students  and 30 students as subjects in a wide trial. The results showed that the feasibility of teaching materials was categorized as very feasible and practical for use at Bina Mulia Mandiri Middle School based on the results of the validator and student response questionnaires. The obstacles that were encountered during the implementation of the research were that it was difficult for students to change their study habits so far, that is, they just sat watching the teacher explain, students sometimes ignored the instructions from the researcher.

Abstract

The purpose of this study was to show whether students' critical thinking skills through solving triangle and square problems are influenced by their prior knowledge. Twenty-five seventh grade students from Madrasah Tsanawiyah At-Taminiyah Sui Kupah participated in this study. The research method used in this study was quantitative. Instruments in the form of multiple choice questions that tested prior knowledge and essay questions that tested critical thinking were used to collect data. The data analysis technique in this research is quantitative data analysis in the form of normality test, linearity test, homogeneity test, and hypothesis testing using simple linear regression test. The findings of this study show that the extent to which students' prior knowledge affects their critical thinking ability varies widely. The calculated Sig value of 37.080 and R-squared value of 61.7% provide strong support for this. The findings show that students with strong background knowledge also have strong critical thinking skills, while students with less background knowledge also have poorer critical thinking skills.

Abstract

The purpose of this study was to determine the extent to which students solve problems in mathematical understanding skills in statistics material. The method in this study is descriptive qualitative and data collection is given 3-point statistics questions in the form of descriptions. The research subjects were class VIII which amounted to 6 people. The results of the researcher's analysis show that mathematical understanding ability is still low in statistics material. Some of the difficulties experienced by students are that students still have difficulty reading the questions given, students' ability to understand the problem is still lacking, students' difficulty in writing the formula given, students' lack of accuracy in prerequisite material, students answer questions carelessly, so students do not solve the problem correctly. Difficulties in this study can be caused by students not paying attention to the teacher's explanation and even still lacking accuracy in understanding the problem, reading questions in the form of description questions, the way students think about mathematics comprehension skills is still difficult. Therefore, it is necessary to have an improvement and follow-up in future research to improve students' mathematical understanding ability in statistics material or better yet, it can replace other materials.
