Abstract

Students’ who have low mathematical anxiety cause themselves more confidence in learning mathematics and solving given problems, while mathematical habit of mind is a key aspect of student success in learning mathematics. This study aims at investigating the association of mathematical anxiety and habit of mind of high school students’. This study is survey research and it was conducted in a public senior high school in Karawang, West Java, Indonesia. The sample of this research consists of the 11th grade were 501 students’ taken using the cluster sampling method. The instrument used in this research covers mathematical anxiety and habit of mind questionnaire, and the data were analysed by using confirmatory factor analysis. The results show that students' mathematical anxiety was negatively associated with habits of mind. However, the result of the research indicates that dominant aspects of mathematical anxiety are: negative perceptions of mathematics learning, low mathematical achievement, lack of confidence, and mathematics tests. Meanwhile, the dominant aspect of habits of mind are: persevering, thinking metacognition, and working carefully and precisely.

Abstract

The aim of this study is to develop student worksheets in statistical material based on the theory of didactical situations. The theory of didactical situations was initiated by Brousseau to design learning situations based on a-didactic, milieu, and didactic situations. Model of Plomp’s design research is used to develop student worksheets, consisting of preliminary analysis (curriculum analysis, student learning trajectory, and statistical material analysis), stages of development, and prototype testing (self-revision, expert-review, one-to-one, and small-group tests). In the preliminary stage, interviews were conducted with one teacher and two students, obtaining didactic and epistemological obstacle on statistical material. The didactic and epistemological obstacles gained from interviews became epistemological models in composing the student worksheets. In the self-revision stage, the student worksheets are improved on aspects of language and material conformity. Meanwhile, the assessment of two experts recommends the student worksheets needs to improve the a-didactical situation. At the one-on-one stage to test the readability of the student worksheets tested to five students, in this stage, there is no improvement. Then, in the small group test stage tested to ten students and one teacher in the learning process obtained the conclusion of the student worksheets meets practicality and effectiveness. In general, the results obtained by the student worksheets have fulfilled practicality, effectiveness, and validity based on the theory of didactical situation that contains a didactic situation, milieu, and didactic situations.
