Teaching and learning activities are carried out online during the pandemic situation. This condition makes the teaching and learning process in the classroom requires teaching materials that can support the learning process. However, some teachers still use teaching materials commonly used during face-to-face learning, which is irrelevant for offline learning. Therefore, teachers need alternative interactive teaching materials that can facilitate online learning. This study aims to produce teaching materials in an interactive e-module based on the Realistic Mathematics Education (RME) approach with the content of number pattern that is valid, practical, and have potentially affected the eight-grade students' mathematical literacy skills. The research method used is design research with type of development studies which include two main stages, namely the preliminary design and the formative evaluation. The data collection instruments used were content and media expert validation sheets, student response questionnaires, and pretest and posttest questions to measure mathematical literacy skills. This research produces an RME-based e-module on number pattern material that is valid, practical, and potentially affects mathematical literacy skills. The results showed that the e-module was valid in content and media quality with very good criteria. Next, the e-module has also been practical from assessing student responses with good criteria. Finally, the e-module can potentially improve students' mathematical literacy skills, which is indicated by the increase in students' mathematical literacy skills after learning to use the e-module. In addition, the e-module developed in this study contributes as alternative teaching material for teachers in the online learning system.

Autistic traits (ATs) include symptoms associated with autism spectrum conditions (ASCs), which are assumed to be continuously distributed across the general population. Studies have indicated the cultural differences in the expression of ATs. Notwithstanding, our literature review indicated that studies on cross-cultural differences in the expression of ATs included samples from different countries. This is the first study designed to compare the expression of ATs between different ethnicities from the same country. Using the Autism-spectrum Quotient (AQ-28), we examined the possible cultural differences in the expression of autistic traits from four groups of students with different ethnic backgrounds, including Turkish (n = 262), Persian (n = 290), Kurdish (n = 300), and Luri (n = 307) students. Behaviors associated with autistic traits were reported overall higher for males than females. Also, significant cultural differences in autistic traits were found that were different for males and females. Furthermore, while the medical sciences student group scored significantly higher than the humanities group in the Imagination dimension, the humanities group had significantly higher scores in Number/Pattern dimensions than the engineering and medical sciences groups. Altogether, our results provide further support for the idea that the expression of ATs is significantly influenced by culture. A significant limitation of the current study was that groups were not matched with respect to age, percentage of male participants, and fields of studies and that these variables may influence the AQ scores.

This study aims to study the relationship between mathematics and culture in Indonesia, one of which is the traditional game of Nasi Goreng Kecap and Mejikuhibiniu. This research is considered important because it teaches students to see real-world activities clearly by being integrated into mathematical ideas. This research uses an ethnographic approach and a library study (literature study) which is a type of qualitative research. The result of this research is that the traditional game Nasi Goreng Kecap and Mejikuhibiniu contains the concept of number patterns, which can be developed in a learning design for number pattern material so that it can change the student's paradigm that mathematics is still considered abstract science to be more fun mathematics
