Abstract

The construction of problem solving is important in the learning process of mathematics. The success of students in solving problems can also be supported by psychological aspects related to student attitudes in the learning process, such as interest and curiosity, self-confidence, open-mindedness, and others, all of which include into a mathematical disposition. Teachers should know the ability of students' mathematical dispositions to help teachers provide the right treatment for problems in constructing problem solving by applying the RME model. The research method used is a concurrent embedded strategy mix method. This research was conducted at SMP 3 Bae Kudus. The subjects of this research were students of class VIII SMP 3 Bae Kudus. The instrument used in this research is a mathematical disposition questionnaire, problem solving test results, and interviews. The results showed that there was a positive correlation between students' mathematical disposition abilities and students' problem solving construction using the RME model. The higher the student's mathematical disposition, the higher the problem-solving construction ability, supported by the application of RME.

Abstract

It is undeniable that Higher Oder Thinking Skills (HOTS) have become the center of attention and essential skills needed, especially in mathematics today, but there are so many research shows that the average thinking ability of Indonesian students is still low. One of the student's low thinking abilities cause is teaching materials that still dominated by questions in the Low Order Thinking Skills (LOTS) category. Therefore, this study aims to develop valid, practical, and effective interactive student worksheets to improve tenth-grade students' higher-order thinking skills. This research used Research and Development (R&D) designs and methods guided by the ADDIE development model with five steps: Analysis, Design, Development, Implementation, and Evaluation. The data obtained from this study is quantitative and qualitative data, which was obtained from the interview, validation test sheet, students and teacher response sheet and pretest-posttest result. The assessment from experts from both the material and media shows that the worksheet is valid with 4.30 and 3.97 average scores. Furthermore, based on the questionnaire responses of teachers and students with the "Excellent" score category, it shows that the developed interactive student worksheet is practical. The interactive student worksheet is also effective in improving mathematical HOTS of tenth-grade students since there is a significant increase in students' mathematical higher-order thinking skills based on student learning outcomes with 0.64 value of N-Gain. Besides the N-Gain, the students' response through the learning after using the interactive worksheet was also in the "Excellent" category, with an average score of 4.54 in the small trial and 4.27 in the field trial. Therefore, this study has produced a valid, practical, and effective interactive student worksheet to improve tenth-grade students' mathematical Higher Order Thinking Skills (HOTS).

Abstract

The mosque is the oldest Islamic culture which is the centre of civilization for Muslims for every group, both adults and children. However, so far the mosque environment is rarely used as an effective learning resource to explore more contextual, meaningful and educational mathematics material. The purpose of this study was to explore mathematics teaching materials and religious values from objects (artefacts) around the mosque. The artefacts explored are mosque objects that have religious values, namely prayer rugs, prayer rugs, mosque reliefs and covers of the Qur'anic manuscripts. The research location is in the Baitu Usyaqil Quran (BUQ) Mosque and the Pesantren Darussalam Purwokerto Mosque, Banyumas, Central Java. The data collection method uses observation, documents and a literature review. The data analysis technique used descriptive qualitative analysis. The results showed that, prayer rugs, prayer rugs, mosque reliefs and covers of the Qur'anic manuscripts contain various transformational geometry concepts such as symmetry, reflection, translation, rotation, and dilation. The results of this study are very important for developing a mathematics curriculum based on student culture.
