Abstract

This article aimed to examine multigroup invariance of Mathematics Self-efficacy and Attitude Scales (MSAS) and examine the differences of MSAS in term of gender. 1135 (630 female and 505 male) Year 9 students in Aceh, Indonesia were involved in the study. The invariance analysis was performed to investigate whether the items in the MSAS are behaving identically for Year 9 female and male students in the province of Aceh, Indonesia. The results reported the indication of multigroup equivalence of the MSAS between gender (p-value is not statistically significant or ∆CFI ≤ 0.01). An independent t-test indentified that students’ attitude concerning mathematics is significantly different between gender of students. Female students’ positive attitude concerning mathematics is higher compared to male students’. This study may be used as one of the evidences as for the needs to enhance male students attitude toward mathematics.

Abstract

During the Covid-19 pandemic, the implementation of online and shift learning systems has been identified as one factor contributing to learning loss in mathematics problem-solving skills specifically in plane geometry problems. The primary objective of this research was to investigate the different types of errors committed by junior high school students in Banda Aceh, Indonesia, in solving plane geometry problems using e-learning diagnostic tests. A descriptive qualitative approach was adopted, and 24 Year 8 students were selected as subjects. The data were collected through tests and interviews, and data analysis involved data reduction, data presentation, data verification, and drawing conclusions. The findings revealed that the percentage of students' errors in solving conceptual problems, principal problems, and verbal problems were 76.39%, 68.75%, and 75%, respectively. Subsequently, the results from the second test and interviews with six students showed that students encountered several conceptual errors, including errors in stating angle symbols, errors in identifying the type of shape provided, errors in deducing information regarding properties, perimeter, and area of plane geometry, lack of knowledge regarding the application of the appropriate plane geometry formula, and inability to solve problems using the correct procedure. Principal errors were related to algebraic operations, while verbal errors involved translating problems and improper application of concepts and principles. The understanding of the types of errors will help teachers detect errors made the students early.
