Abstract: This research aims to describe the spatial ability of grade VIII students SMP Kristen GPID Palu in Solving Flat Geometry Problems in Flat-Side Space Based on High. The type of this research is a case study research with a qualitative approach. The subject that use in this research are the students who have high mathematical abilities (ST). The research subjects were given geometry tests to construct a flat side space problem I and then interviewed. To test the credibility of the data, time triangulation was carried out by giving geometry tests to construct the flat side space of problem II and conducting interviews. Based on the results of the analysis it was found that in spatial perception ability, ST were able to determine unit cubes located in the horizontal position and vertical position in the cube stack after being manipulated. Besides that for mental rotation ability, ST is able to rotate the position of the cube and imagine the rotation of the cube correctly. ST determines the change of the cube after being rotated 900 counterclockwise by imagining rotating the cube right to the left. As well as in spatial visualization ability, ST is able to determine the change of cubes into different forms and recognize changes in position of the elements of the cube. ST is able to determine the location of the triangle, circle, and quadrilateral image in the cube network that shows the inside of the cube after being rotated twice.

Abstract

This research pupose to describe the misconceptions and the impacts about the pythagorean and circumference at Class VIII SMP GKST Imanuel Palu. This study used descriptive qualitative method. Data collection techniques using written tests. Checking the validity of the data with the triangulation technique method, which compares the results of tests and interviews. Data analysis consists of 3 phases, namely data reduction, data display and conclusion drawing. Based on data analysis and discussion, misconceptions occur in students which include: the pythagorean material: ((1) There is a wrong concept in planning problem solving which causes students to be unable to use the opposite Pythagorean concept (2) Students generalize the use of concepts that look the same but are different in meaning and use. In the circle material: (1). Implement the wrong circle area formula (2). Misunderstanding of concepts in the area of ​​the circle formula, (3). Misunderstanding in connecting concepts to problems. Misconceptions experienced by students are caused by: (1). the existence of associative thinking in which students associate or classify a concept is always the same as other concepts, (2). the existence of wrong intuition when planning problem solving, (3). there are students' preconceptions that are not in accordance with the operation of numbers in the Pythagorean formula.

Abstract

This research is a descriptive study that uses a qualitative approach aims to obtain a description of the problem solving ability of two variable linear aquation system of grade VIII students of GPID Sumbersari Christian Junior High School in terms of cognitive style based on Polya's steps. Subjects in this study consisted of 4 students, namely subject FIt (selected students who are FI cognitive style from the GEFT test results which fall into the high FI category), Subject FIs (selected students who are FI cognitive style from the GEFT test results which fall into the medium FI category), FDs (selected students who are FD cognitive style from the GEFT test results which fall into the medium FD category) and subject FDr (selected students who are FD cognitive style from the GEFT test results which fall into the low FD category). The instruments in this study are GEFT test, problem solving ability test of two variable linear aquation system, and interview guidelines. The results showed that the problem solving ability of FI cognitive style subjects is better than FD cognitive style subjects. Where, the problem solving ability of two variable linear equation system of FI cognitive style subject that is FIt subject has been in accordance with the four stages of Polya by giving the correct conclusion and FIs subject has also been in accordance with the stage of understanding the problem and planning problem solving however, there is a calculation error at the stage of implementing the problem solving plan and at the stage of re-examining the answer the conclusion obtained is wrong. Meanwhile, the problem solving ability of the two variable linear equation system of FD cognitive style subjects, namely FDs and FDr subjects even though they are in accordance with the stage of understanding the problem, and planning problem solving. However, at the stage of performing the problem solving plan is incomplete and at the stage of checking the answer the conclusion obtained is wrong.

Abstract

This study aims to analyze students' attitudes toward mathematics learning based on the five affective domain dimensions of Krathwohl: Receiving, Responding, Valuing, Organization, and Characterization. The research employed a quantitative approach using a survey method. Data were collected from 447 junior high school students in Palu City through questionnaires and analyzed using the Rasch Model to evaluate item quality and student ability across each attitude component. The results indicated that most students fell into the low to moderate attitude categories, with logit distributions concentrated below the average value. Item reliability across all components was in the very high category (≥0.96), indicating strong instrument consistency in measuring the targeted constructs, while person reliability in components such as Organization and Receiving remained relatively low. The Wright Map analysis revealed a mismatch between students' ability levels and the difficulty of certain items, particularly in components requiring value internalization. These findings underscore the importance of implementing instructional strategies that holistically foster students' affective development. The study recommends reflective, participatory, and contextual learning approaches to strengthen students' positive attitudes toward mathematics learning in a sustainable manner.
