Abstract

The Covid-19 pandemic has caused the learning process to be hampered and cannot be carried out face-to-face. Therefore, a solution is needed for this problem. One alternative to overcome this problem is online learning. This study aims to describe the effectiveness of online learning using online media during the Covid-19 pandemic in Mathematics courses. The subjects of this study were 51 students in the Faculty of Science and Technology, Nahdlatul Ulama University, Purwokerto. They were from five different study programs, namely Agrotechnology, Mathematics, Biology, Fisheries Science, and Agricultural Biosystems Engineering, who had taken mathematics courses. This study was carried out in June – August 2021. This study used closed, semi-closed, and open-ended questionnaires as research instruments. Then, the data collection procedure was done through Google Forms. The data obtained were then selected using purposive sampling. To get valid and reliable data, triangulation was applied in this study. Triangulation was carried out through interviews with five students whose data were selected randomly. The researchers used descriptive statistics as the data analysis. The study found that the activities most often carried out by students during Study From Home (SFH) are playing on cellphones or laptops, doing assignments, working, and sleeping. Then, related to online learning, students prefer to use WhatsApp Group media and lectures. The preferred assignments or assessments are individual assignments and quizzes. Furthermore, the learning model most favored by students is the face-to-face learning model because students consider online learning ineffective. The results of this study can be used as a reference in choosing the suitable model, method, and learning media. Therefore, online learning can be held effectively and easily accepted by students during the Covid-19 pandemic.

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.
