Abstract

Some research about identifying the differences between male and female students’ written communication skills has been done before. However, the previous research only focused on qualitative studies. Therefore, there is still a lack of empirical proof of the result. This study aims to test whether a significant difference exists between male and female students' written mathematical communication skills and identify their performance difficulties. The subjects were 14 male and 14 female students at the junior high school. The instrument was a test of mathematical communication skills on quadrilateral topics. The research method used was a mixed method with a sequential explanatory design. The data were analyzed using Mann-Whitney U to measure the difference between male and female students’ written mathematical communication skills, and document analysis was conducted to analyze their difficulties in performing written mathematical communication. The results showed that even though there is no significant difference between written mathematical communication skills between male and female students, there is a significant difference when viewed from each indicator.  In addition, the difficulties experienced by male and female students are difficulties expressing mathematical ideas using mathematical symbols, using facts and concepts to solve problems, and operating algebraic forms.

Abstract

This research aims to analyse a mathematics HOTS instrument using the Rasch Model to provide a better measurement instrument for mathematics. The result showed, based on Rasch Model analysis, 1) from 20 items, there are only ten items that can be used to measure HOTS of students in mathematics with the difficulty of 3 items being hard and seven items being easy; 2) the reliabilities of the instrument are moderate; 3) the instrument only can divide students into two groups of level ability; and 4) there is no significant differential item functioning (DIF) bias detected on the instrument.
