Abstract

This study explores the conceptual understanding of visually impaired students regarding circle elements using a learning tool called the Circle Box, which incorporates auditory and tactile features to help students identify circle elements and facilitate subsequent learning. A qualitative naturalistic approach was employed, involving five 8th-grade visually impaired students and two mathematics teachers at a special school in Cimahi. Data were collected through observations, interviews, and a test adapted from Adding It Up: Helping Children Learn Mathematics by the National Research Council. Data were analyzed through reduction, descriptive presentation, verification, and conclusion. The results show that most students successfully identified circle elements and understood key relationships, though challenges remain in verbal explanations and generalizations involving unfamiliar vocabulary. Factors such as age, gender, and the level of visual impairment influence understanding, impacting memorization and confidence. Recommendations for improvements emphasize sound quality, simplified language, and enhanced tactile designs for better usability and learning efficiency.

Abstract

The purpose of this study is to obtain descriptive results regarding the application of the ctl model assisted by geogebra to improve mathematical understanding before and after the implementation of the ctl teaching approach assisted by geogebra in class viii smpn satap jayakerta for systems of linear equations in two variables material. 10 students were the subjects in this study. experiments in the form of comprehension ability test questions are the methods applied in this study. data analysis was carried out by implementing the pre-experimental design with the one group pretest-posttest design design. the findings in this study indicate that there is an influence of the ctl teaching approach using geogebra, found in the data analysis that has a sign value ≤0.05 which means that there is an increase in mathematical understanding before and after the implementation of the ctl teaching model assisted by geogebra for systems of linear equations in two variables material.
