Abstract

The Covid-19 pandemic has greatly impacted various worlds without exception in the field of education, especially in Indonesia. This situation causes learning that is usually done face-to-face to turn into online learning making students find it difficult to understand the material given. This study aims to determine the mathematical problem-solving ability of MTS Thariqul Hidayah students, Indragiri Hulu Regency in class VII MTS Thariqul Hidayah students as many as 25 students and to describe the level of problem-solving ability categories in each item statement of questions that have been given in the form of descriptive questions consisting of 5 questions. The research method uses qualitative descriptive analysis to find out the extent to which the category achievement is based on problem-solving indicators during the covid-19 pandemic. Based on the ability analysis carried out by students in working on mathematical problem-solving questions with Linear Equations and Inequality One variable found that the student problem-solving process is very low. The instrument used is a question that has been tested for reliability, validity, discriminating power, and difficulty. Generally, the achievement of indicators of problem-solving ability has not been fully achieved due to ineffective learning and lack of interaction between teachers and students. The results showed that there were still student errors in solving mathematical problems in each problem-solving indicator.

Abstract

This research is research on developing learning tools and applying Realistic Mathematics Learning (PMR) with the material Function. In the initial research, it appears that the teacher is still not maximally teaching according to the syntax or PMR steps. This is because the teacher does not understand the PMR learning tools that the teacher has just obtained, but the teacher has understood them in the next meeting. Students/students also have problems understanding the syntax of learning steps. This apparent difficulty is because students also get a different learning approach than usual. It is also seen that students have difficulty expressing their ability to read pictures or read problems. The researcher applies a modified four-dimensional model Thiagarajan, Semmel, and Semmel to produce relevant teaching materials. The teaching materials obtained consisted of (1) lesson plans, (2) teacher guidelines, (3) student books, (4) student activity sheets, and (5) learning outcomes tests. The experiment results found that the realistic mathematical approach was effective in functional learning in class VIII students of SMPN 1 Sungai Lala, Riau Province.
