Abstract

This study aimed to analyze in depth the students' independent thinking ability in solving combination problems in combinatorics material. The research method used was a qualitative case study, involving 24 high school students in grade XI who were selected purposively based on the criteria of never having studied the concept of combination formally and never having faced similar problems. The research instrument consisted of specially designed combination story problems and semi-structured interview guidelines to explore students' cognitive processes. Analysis was carried out on four aspects of ability, namely: (1) the ability to state problems in other forms, (2) the ability to form a solution strategy, (3) the ability to apply strategies for solving, and (4) the ability to verify the results obtained. The results of the study stated: (1) problems were stated in the form of number symbols and diagrams, using narrative sentences, drawing circles, forming sets, and using symbols B1 to B6; (2) the solution strategies used included: counting with the help of symbols, counting directly without symbols, and counting alternately; (3) solutions were found by using a variable symbol and set approach; (4) no students verified their solution results. These findings confirmed that although the majority of students demonstrated independent thinking in problem-solving and strategy development, only a small proportion consistently implemented the strategy, and none verified the results. The implications of this research could serve as a reference for designing more effective learning strategies to develop students' independent thinking skills in mathematics, particularly in combinatorics.

Abstract

Measures of central tendency, such as the mean, median, and mode, are fundamental concepts in statistics that can be used to support decision-making. The purpose of this study is to describe how university students reason about measures of central tendency when comparing two age distributions of patients presented in the form of frequency polygons, from a commognitive perspective. This study employs a descriptive qualitative method with an exploratory approach. A total of 37 students participated in the study, four of whom were selected as research subjects—two representing the calculative category and two representing the visual-interpretative category. The research instruments consisted of one problem related to measures of central tendency and an interview guide. The problem included three questions, each presenting data in the form of frequency polygons. The data were thematically analyzed using Sfard’s commognitive framework, focusing on four components: word use, visual mediators, routines, and narratives. The findings reveal that students in the calculative category predominantly used visual mediators and routines. In contrast, students in the visual-interpretative category emphasized the use of word use to construct narratives. Keywords: commognitive, reasoning, measures of central tendency, frequency polygon

Abstract

This study aims to test the compatibility of structural equation (SEM) models to determine the relationship between mathematical reasoning ability and geometry problem solving ability. Using an ex-post facto research design, this study took a random sample of 100 students from a total of 296 mathematics education student population at a university in Lubuklinggau. Data were collected through mathematical reasoning tests and geometry problem-solving tests, then analyzed using the Lisrel 8.8 and SPSS programs. The results of the analysis show a very significant path coefficient, which proves that mathematical reasoning ability has a positive direct relationship with geometry problem-solving ability. This means that an increase in reasoning skills will be followed by an increase in the ability to solve geometry problems. In conclusion, this study confirms the existence of a direct relationship between the two variables, where mathematical reasoning ability contributes 15.13% to the improvement of geometry problem-solving ability.
