Abstract

This study aims to give a comprehensive account of pre-service secondary mathematics teachers’ understanding of absolute value. Thirty two-item absolute value understanding test was developed and administered to thirty-eight students attending mathematics education department at one private university in Jakarta City, Indonesia. Five of them were selected purposively and interviewed to gain deep information and confirm their written responses in the test. We find that most participants struggled with the absolute value task. There are inconsistencies of the definition of absolute value expressed by them. Besides, typical mistakes made are: (a) removal of absolute value bars; (b) focus heavily on rules; (c) conversion of absolute value bars to parentheses; (d) exclusion of number inside absolute value bars; (e) poor algebraic manipulation; and (f) inability to draw absolute value graph. Based on the findings, the most common cause of mistakes made by the participants is didactical contract in mathematics teaching and learning. Limitation and implications of the study are presented.

Abstract

This study aims to determine the differences in STAD type cooperative learning on geometry material integrated with the website www.fooplot.com. The subject of this study was a private junior high school in Bekasi, which is consisted of 31 male students and 40 female students. This study uses a quasi-experimental design method. Data from the research will be analyzed using descriptive statistics. The results of the study have shown that learning mathematics using a website has assisted students to improve their understanding of geometric concepts. The learning with the website has supported students to study independently outside of school hours. Website applications can encourage students to examine student work independently.
