Student's Ability in Explaining the Concept of Solid Figure's Volume Reviewed From Visualizer Verbalizer Cognitive Style

Abstract

Students who choose mathematics education majors should prepare themselves to become mathematics teachers in schools. What should a teacher prepare before teaching? The answer to this question is very complex, considering that there are many aspects that the teacher must have prepared. However, the first fundamental thing that a teacher provides is the concept of material that must be really mature so that there are no conceptual errors when explaining. Based on the author's experience as a lecturer in the course of Mathematical Studies and

Students' Mathematical Argumentation with the Visualizer Cognitive Style in Proving the Congruence of Triangles

“…S2 and S3 subjects provide assumptions or interpret the images provided without validly collaborating with the data. Students' ability to explain geometric problems not only requires mastery of concepts, but also requires skills in representing problems into mathematical models (Indahwati & Fetty, 2022). Students with a visual learning style tend to be able to convey their ideas with visual representations and create pictures to facilitate solving problems.…”

“…The subject's ability to reason and partition triangular images as above is related to the characteristics of the visualiser subject, where it is easier for the subject to solve problems by using images or partitions of a composed image. Subjects who have a visualizer cognitive style are more image-oriented and prefer visual games, such as putting together puzzles (Indahwati & Fetty, 2022;McEwan & Reynolds, 2007;Mendelson, 2004;Shodikin, et al 2023) From the 2 triangles that S1 took out from triangle ABC, S1 easily explained that with the concept of congruence based on the side-side-side theorem, where the three pairs of corresponding sides between triangle ABD and triangle ABE are congruent. This can be seen in S1's answer to statement number 4 .…”
