Abstract

The purpose of this study is to describe students misconceptions on the material of algebraic fractions in terms of the cognitive style of seventh grade students of SMP Negeri 14 Palu. This type of research is descriptive qualitative research. The subjects of this study were 2 students consisting of one student who had a reflective cognitive style and one student who had an impulsive cognitive style, taken from 17 students of class VII Swallow at SMP Negeri 14 Palu. Misconceptions were identified using a written essay test accompanied by the Certainty of Response Index (CRI) method and interviews. The results of this study indicate that students who have reflective and impulsive cognitive styles experience misconceptions: (1) students misconceptions with reflective cognitive style occur in connecting between concepts of fractional division operations in algebraic forms, the cause of students misconceptions with reflective cognitive style comes from students wrong thinking and lack of student learning experience, (2) students misconceptions with impulsive cognitive style occur in using the concepts of addition and subtraction and the concept of adding integers, misconceptions in connecting between concepts and misconceptions in interpreting the concept of adding terms like algebraic forms, the cause of students misconceptions with impulsive cognitive style comes from students' wrong thinking, lack of accuracy of students in solving problems, lack of student learning experience and have a wrong understanding of the concept.

Abstract

This research is motivated by students who experience problems in solving multiplication matrix problems and tend to be passive in the learning process. This research is a Classroom Action Research (CAR) which refers to the research design of Kemmis and Mc. Taggart namely (1) planning, (2) implementation of action (3) observation and (4) reflection. This study aims to describe the application of the cooperative learning model using structured training methods to improve student learning outcomes in class XI IPA 1 SMA Negeri 7 Palu. The subjects of this study were 32 students of class XI IPA 1, consisting of 15 male students and 18 female students. Of the 32 students, three students were selected as informants with high, medium and low skills. The results of the study the application of cooperative learning models with structured training methods can improve student learning outcomes in class XI IPA 1 SMA Negeri 7 Palu on Matrix Multiplication Material. The results of the final action test cycle I showed that of the 33 students who took the test, there were 11 students who achieved the learning objectives and 22 students did not achieve the learning objectives. The results of the final action test in cycle II showed that the student's score had increased from cycle I. Of the 33 students who took the test, there were 27 students who achieved the learning objectives and 6 students who did not achieve the learning objectives and 1 who did not take the test because they did not attend. From the results of the action test in cycle I and cycle II, it can be concluded that there was an increase in student learning outcomes from cycle I to cycle II

Abstract

This study aimed to obtain a description of the critical thinking of students in class VII SMP in solving problems on the material of build flat triangle. This type of research is descriptive-qualitative with a case study approach. In this study, three students were selected, each of whom had high, medium and low mathematical abilities. Data collection techniques in this study by providing questions about the triangle material and interviews. The triangle material was chosen because it can trigger students to use their higher-order thinking skills. The results of this study indicate that the critical thinking profile of students in class VII of SMP Negeri 1 Mepanga in solving problems on the material of build flat triangle is as follows, the critical thinking profile of students with high mathematical abilities (PM) includes, providing simple explanations, building basic skills, solving skills problem and conclude, the critical thinking profile of students with moderate mathematical ability (SR) includes, providing simple explanations, problem solving and concluding abilities and the critical thinking profile of students with low mathematical ability (AL) only provides a simple explanation.
