Abstract

Misconception is one of the serious obstacles in mathematics learning. Sets material, especially the concepts of the empty set and the universal set, often become sources of misconception for students. Main learning sources such as textbooks play a large role in shaping this conceptual understanding. This study aims to analyze and identify potential misconceptions in the material on the empty set and the universal set in 7th grade mathematics textbooks, as well as the possible impacts on students. The method used is descriptive qualitative through literature study and content analysis. The material analyzed in this study is the “Set Theory” chapter in the “Mathematics Grade VII Semester 1” textbook published by the Ministry of Education and Culture. The results show that although the book has defined the empty set, the explanation is not sufficiently complete and in depth. The absence of an explicit explanation that the empty set is a subset of every set, including the universal set, potentially causes misconception. As a result, students may experience misunderstanding of basic concepts, difficulties in set operations, and confusion in interpreting the universal set. It is concluded that the presentation of empty set material in the textbook needs improvement by giving more comprehensive explanations and contextual examples to prevent misconceptions. The implication of this study is the importance of a strict review of textbook material to ensure the accuracy of the concepts conveyed.

Abstract

This study aims to analyze mathematics education students’ understanding of the basic concepts of Euclidean geometry in terms of its basic elements, axioms, postulates, and propositions. A descriptive quantitative approach was used with 42 students from the University of Medan who had taken the Euclidean Geometry course as subjects. The instrument consisted of a 10-item multiple-choice test measuring six indicators. The data were analyzed descriptively. The results showed an average score of 84.76 (Very Good category). Fifty percent of the students fell into the Very Good category and 50% into the Good category; no students were in the Fair, Poor, or Very Poor categories. The score distribution was not normal (Shapiro-Wilk p<0.05) with a sample standard deviation of 11.31. Preliminary analysis of the indicators revealed very good understanding of basic elements, postulates, and simple proofs, but weak performance in the application of concepts (only 39.13% correct) and the concept of axiomatic independence (52.17% correct). Although the overall results appear high, weaknesses in applied reasoning and axiomatic structure still need to be addressed. The study recommends strengthening the teaching of deductive reasoning and providing practice in applying theorems in non-routine contexts
