Abstract

The purpose of this study is to determine the level of student thinking based on gender differences by exploring students 'geometrical thinking abilities and creating learning examples to improve students' level of thinking. While the differences in mathematical abilities are high, medium and low mathematical abilities. This type of research is exploratory research using a naturalistic qualitative approach, by taking 3 male students and 3 female students as research subjects which are then grouped based on mathematical abilities. The results of each activity are analyzed and the level of thinking of each research subject is determined. All subjects still ignored class inclusion of quadrilateral shapes even though they were able to distinguish geometric shapes based on the properties of the components. the sequence of learning phases revealed by van Hiele, namely: (1) Information Phase (Information), (2) Guided Orientation Phase, (3) Explicitation Phase, (4) Free Orientation Phase Orientation), and (5) Integration Phase. The results obtained are that both male and female students are at the level of thinking 1. It is different from the difference in students' level of thinking when viewed from their mathematical abilities. For students who are in the high and medium grades, all students are at level 1 thinking, whereas in the low value group only one student is at level 1 thinking and the others are at level 0 thinking. While the learning examples made are Learning Implementation Plans (RPP) and Student Worksheets (LKS) are made with the hope of increasing the level of van Hiele students' geometry thinking from level 1 to level 2.

Abstract

The process of learning mathematics still uses conventional methods where the teacher dominates the learning process, so still experience learning difficulties, especially understanding concepts and mastery of geometry which causes learning outcomes to decline. This causes students to be passive and only accept the teacher's explanation in other words students are not directed to think to find solutions to the problems at hand. Problem-based learning is learning that makes students active and can find their concepts and be more effective. In addition to problem-based learning. learning must use media that support a more effective teaching and learning process. The use of teaching aids is very influential on the success of the teaching and learning process. The type of this research is experimental research and quantitative approach. The population in this study were all students of class VII SMP Rewarangga while the sample was taken by random sampling totaling 14 students. The data analysis technique used Covariance Analysis (ANACOVA). The learning device meets the requirements of validity, and good sensitivity reliability. The learning tools include Learning Implementation Plans (RPP), Student Worksheets (LKS), and Learning Outcomes Test (THB). Based on the results of Anacova with homogeneity test, from the calculations obtained F count = 1.0787 and F table¬ with a significance level of 5% = 1.98, so F count < F table causes to accept H0 and reject H1 which shows the variance of the two samples is homogeneous. This shows that problem-based learning assisted by teaching aids can improve student learning outcomes for geometry material.

Abstract

This study aims to describe and analyze the types of mistakes made by students based on their respective abilities. The research method used is qualitative. The research was conducted at SMA Widya Bhakti, with 6 subjects in class XI MIA. The instrument used was first-semester report card grades for math skills, problem-solving tests and interviews. The data collection technique comes from the answers to written tests and the results of student interviews. Data analysis was carried out qualitatively with the steps of data reduction, presenting data, and drawing conclusions. The results of this study can be used as an effort to improve students' abilities in solving contextual problems in the material of arithmetic sequences. Based on the research results, information was obtained that there were causes of student errors in solving contextual questions based on students' mathematical abilities. One factor that causes high-ability student errors is careless mistakes. Factors causing the errors of students with moderate abilities are errors in reading instructions in questions, conceptual errors, conceptual errors and errors during tests. Causative factors Factors that cause low-ability students' errors are errors in reading instructions, careless errors, application errors, conceptual errors, test errors, and learning errors.
