Students often experience difficulties and errors in solving quadratic inequality problems. These difficulties and errors are not only caused by students’ ignorance or misconceptions, but also caused by epistemological obstacles. This study aimed to determine the epistemological obstacles faced by the junior high school students in quadratic inequality. This research was a qualitative research that involved 105 ninth-grade students at one of the junior high schools in Bandung, Indonesia. The data were collected through open-ended tasks and task-based interviews. The data were analyzed using the inductive coding process to classify students’ errors. The descriptive analysis was carried out to reveal students’ ways of understanding and ways of thinking behind each error to be compared with historical analysis. Based on the description of ways of understanding and ways of thinking and comparison with this historical phenomenon, the epistemological obstacles had be confirmed. The results showed that there were epistemological obstacles in quadratic inequalities. The epistemological obstacles consisted of students' quadratic equation knowledge acts and students' arithmetic knowledge acts. However, no epistemological obstacles were found in the development history of quadratic inequality. Students' epistemological obstacles were parallel to the historical phenomena of quadratic inequality.

Preservice mathematics teachers (PSMTs) need to master teaching material besides pedagogical competence. This knowledge is a combination of conceptual and procedural knowledge. Teachers should possess the ability to explain a concept, the reason for the concepts used, and the relationship among several concepts clearly and effectively to identify why the concept is used. This study aimed to identify the conceptual and procedural knowledge of PSMTs in Linear Algebra courses. Data collection was carried out through tests and interviews. The interview was conducted with several participants to clarify their test answers. The participants' interview answers revealed that they had difficulty in choosing the proper concept answering modified questions. Also, the participants tried to answer the question using a procedural approach. According to the findings, it is vital to construct appropriate teaching materials appropriate for the learning objective and material map concept.

Millennials currently prefer web-assisted interactive media as a learning resource rather than reading books. To understand the contents of the book, students need high literacy skills. Unlike the web-assisted interactive media, the explanations are accompanied by pictures and simulations that can help students to understand the learning material. The developed web-assisted interactive learning media had been adjusted to the 2013 curriculum. This research aimed to develop a valid, effective, and practical interactive web-assisted learning media. The research development model used was the 4D model which consisted of Define, Design, Development, and Dissemination stages. The instrument used in this study was a validation sheet, a questionnaire to measure the practicality, and a creative-thinking test to measure the effectiveness. The results of validation showed that the developed learning media obtained an average score of 86.17% and had met the validity criteria with excellent quality. The questionnaire obtained a score of 88.39% which indicated that the developed learning media was effective. The developed web-assisted interactive learning media met the effectiveness criteria with the obtained average score of 80% based on four indicators, namely fluency, flexibility, authenticity, and detail. It can be concluded that the web-assisted interactive learning media is suitable to be used as a learning resource.

Mathematical creative thinking ability and self-efficacy are a combination of abilities students need to have when studying mathematics. Mathematical learning is expected to improve both abilities. However, teachers still use conventional learning such as direct teaching, which results in a low increase in students' mathematical creative thinking abilities and self-efficacy. So we need alternative student-centred learning and teachers as facilitators who provide scaffolding. The study was conducted to obtain a description of the discovery learning process with scaffolding which aims to improve the ability to think creatively and self-efficacy. Two quasi-experimental designs with three class groups were used: The Matching-only Pretest-posttest Control Group Design was used to measure mathematical creative thinking skills, and The Matching-only Posttest-only Control Group Design was used to measure the self-efficacy scale. Based on the results of one-way ANOVA, the mathematical creative thinking ability of students discovery learning with scaffolding is better than discovery learning and conventional learning. Likewise, this happens to 'self-efficacy, based on the one-way ANOVA that students' self-efficacy of discovery learning with scaffolding is better than discovery learning and conventional learning. The learning process of discovery learning with scaffolding has a positive impact on the improvement of mathematical creative thinking abilities and self-efficacy
