Abstract

English The study aims to analyze the types of errors made by students in solving algebraic operations material questions for class VII SMP Dominico Savio Manado and to find out the factors that cause students to make these mistakes. The type of research used in this research is descriptive qualitative. Data collection techniques were carried out by giving tests and inetrviews. The results of the analysis in this study indicate the types of errors made by class VII students of SMP Dominico Savio Manado in solving problems on the operation material of algebric forms, namely conceptual errors of 66,67%, procedural errors of 55,55%, and computational errors 83,33%. The factors that cause students to make mistakes, namely students do not understand the meaning of the questions given, students are less careful in performing arithmetic operations, and students are in a hurry to solve questions abaout operations in algebraic forms.

Abstract

Research on learning the limit of algebraic functions is carried out using the PIMCA model. This study aims to find out how to improve student learning outcomes in learning the limit of algebraic functions with an exhibition integrated group discussion strategy with the PIMCA model. PIMCA (Presentation, Idea Mapping, Conceptualization, and Assessment Formative) which was introduced and developed by Cosmas Poluakan. This research was conducted at the Department of Mathematics Education, Manado State University, with 21 students as respondents. From the results of data analysis, the average value of the pretest was 12.57 and the average value of the posttest was 58.57. The increase in concept understanding from Idea Mapping to Concept Maps increased by 80.71%. Student skills at the time of presentation, mastery of the material and problem solving where the average student has received a very good assessment. There is an increase in student learning outcomes. The PIMCA learning model can help students understand the correct mathematical concepts. The PIMCA learning model is a new learning model that can be used as an alternative learning model in the STEM field.
