A Commognitive Framework: The Process of Solving Mathematical Problems of Middle School Students

This study aims to describe students’ ability to solve mathematical problems from a commognitive point of view, It will describe their word use, visual mediators, narratives, and routines. This type of research is qualitative research with a descriptive approach. The research method is comprised of four steps: (1) preparation, (2) collecting data, (3) transcribing the data, and (4) analyzing the data. The results of the study showed that the subject manifested visual markers of algebraic expressions in verbal terms and used words symbolically. The subject used sketching as a visual mediator, and the sketch was divided into parts. Narrative was used by students in relation to broad rectangular theorems and the concepts of addition, subtraction, and multiplication. The subject carried out a routine to solve the problem, which consisted of writing down what was known, dividing the problem into several parts, identifying the purpose of the problem, and making a sketch to determine how much fabric remained unused. https://doi.org/10.26803/ijlter.18.2.7
