This study aims to determine the development of mathematical representation skills of junior high school students (SMP) based on mathematical exam results data in 2014-2016. The research data was obtained from responses of students' answers consisting of 1,535 students in 2014 and 2,000 students in 2015 and 2016 classified based on indicators of mathematical representation ability. In addition, the classification of student response data is also by gender and type of school. This research is a descriptive research using tables and graphs to describe data analysis of the development of the ability of mathematical representation in each year. The results show that the average percentage of mathematical representation ability of junior high school students in creating and using representations to organize, record and communicate mathematical ideas decrease every year. In indicators uses representation to model and interpret the physical, social, and mathematical phenomena increase in 2014 to 2015 but decrease in 2016. In general, the average percentage of mathematical representation ability of male students is higher than female.

The Covid-19 pandemic has an impact on all aspects, including education. This pandemic also impacts education in Malang City, and the Education Office has implemented learning from home policy. However, implementation for two semesters shows that both the school and students are relatively not ready to be involved in distance learning activities. This article aims to look at the tendency of learning readiness to understand the material of Junior High School students in Malang City during distance learning. The quantitative survey approach answers questions that answer the purpose of this article. The calculation of Slovin determined student readiness data collected from all state Junior High Schools in Malang City as many as 400 people with a degree of error of 5%. The data technique uses an online questionnaire (google form). The data is managed through the editing, scoring, coding, and tabulating stages, which are the basis for conducting a cross-tabulation analysis. Field findings show that public Junior High School students in Malang City have a high level of learning readiness and tend to understand the material with an average percentage of 60%. The implications of these findings contribute to understanding the implementation of distance learning from the student's point of view regarding the aspect of readiness-recommendations for further research related to how distance learning is managed based on the existing readiness profile.

This study aimed to develop the learning media and investigated the effectiveness of audio-based Pop-Up Book media on the two-dimensional rectangular shape. This media was tested twice in a small group of 6 students and in a large group of 25 students. Respondents were the VIIth grade students. The result of expert validation showed the average percentage of 88,16 % and was considered valid, thus the learning media was allowed to be used and tested. The analysis of effectiveness in small and large groups in a row revealed that students’ respond was very good, with the percentage of 88.1% and 88.87%. In addition, the activities of students in the class were very good, showed by the percentage of 92% and 86.8%. Finally, the classical completeness of the learning outcomes obtained the percentage of 100% from 6 students and 92% from 23 students who completed the test. Therefore, it can be concluded that the application of audio-based Pop-Up Book on the two-dimensional rectangular shape was effective for Junior High School students.

TIMSS results in the number content and number sense ability of students in Indonesia are still low. This research aims to train and familiarize students of the junior high school to work on problems in TIMSS using number sense abilities. The process of developing test instruments in this research was through the stages of the Plomp development model that are (1) preliminary investigation phase; (2) design phase; (3) realization phase; (4) test, evaluation and revision phase, and (5) implementation phase. This research produced a good quality test. The test instrument has met the criteria of valid, reliable, objective and practical included 4 item with high validity categories and 14 items of medium validity categories. The level of reliability is very high with <em>r</em><sub>11</sub> = 0.884, objective from the results of reliability and practical from the student response questionnaire analysis with the average student giving a positive response of 72.1%. The results of the research reveal that the test instruments that can measure the number sense ability are in the low category with an average percentage in the overall number sense indicator of 44.26% and from the interview results, students have not used all the indicators of the number sensing ability well.

The Relationship

The purpose of this study was to elucidate the relationship between the severity of Internet addiction and various media-related applications. The participants were junior high school students between 12 and 15 years old. A total of 529 students (283 males, 246 females) were included. The participants answered Young’s Internet Addiction Test (IAT) and a structural questionnaire about their access to electronic devices and applications. An Internet addiction prevalence of 4.3% (95% CI: 2.8–6.5%) was reported in this study, with an additional 26.3% (95% CI: 22.6–30.2%) of participants possibly addicted. The accessibility of gaming devices was significantly higher in male students than in female students. The use of applications for SNSs was significantly higher in female students than in male students. Twitter accessibility was a factor that contributed to Internet addiction in both genders. The prevalence of severe Internet addiction among school students in Japan was 4.3%, and Twitter was the most important factor associated with this addiction.
