Abstract

This study explores the procedural skills of grade VIII students in solving Pythagorean Theorem problems, focusing on the diversity of problem-solving steps and error patterns that emerge. A descriptive qualitative method was used in this study, with three students selected as subjects based on high, medium, and low levels of mathematical ability. Data were collected through problem-solving tasks and semi-structured interviews to comprehensively understand the students' approaches and strategies. The results showed that students with high procedural skills implemented problem-solving steps in a structured manner, while those with moderate skills often needed to be more consistent in recording critical steps. Students with low skills tended to bypass procedural structures and proceed directly to solutions, leading to a higher rate of errors. Error patterns varied by students' mathematical ability levels: high-ability students made no errors, medium-ability students exhibited errors in illustrations and procedural consistency, and low-ability students struggled with writing expressions and fully implementing steps. These findings emphasize the need for instructional approaches tailored to students' skill levels, such as structured learning and scaffolding, to strengthen procedural skills. A follow-up study with a broader sample is recommended to validate these findings and assess the effectiveness of instructional strategies for enhancing students' procedural skills across various mathematical topics.

Abstract

This study aims to explain students' mathematical processes in solving open-ended problems using a popular context from TikTok, specifically involving the calculation of the size of legit layer cake pieces as presented by the TikTok user Ci Mehong. Descriptive qualitative method is the research paradigm used to explain the mathematical process. The subjects were 81 eleventh-grade students who were instructed to take the test. Data collection was carried out by giving tests and diagnostic interviews conducted at the same time when students answered the questions, then the data were analyzed using a combination of thematic analysis techniques and flow models based on mathematical modeling indicators. The results showed numerical, graphical, algebraic, and verbal representation forms in the real situation-real world model process. In the real world model-mathematical modeling process, students demonstrated the use of diverse mathematical concepts, including cuboid volume, geometric sequences, exponents, and arithmetic operations. While in the mathematical modeling-mathematical result process, students derived results in volume and length units, which were then contextualized back to the real-world situation by making assumptions about the number of cake pieces per person.
