Abstract

An event or problem sometimes needs to be predicted to determine the impact caused. One of the events that need to be predicted is the impact of the earthquake. The Meteorology, Climatology and Geophysics Agency (BMKG) classifies earthquake impacts based on the BMKG Earthquake Intensity Scale (SIG-BMKG) which consists of 5 scales. In making predictions on a problem, you can use data mining that extracts data into useful information. Grouping the impact of an earthquake is one of the tasks of data mining, namely classification. Prediction can be viewed as a classification that groups data into predefined classes. One classification method is the Decision Tree. This method can handle both categorical and numerical data on large data. Some of the algorithm of the Decision Tree method are ID3, CART, and C4.5. The C4.5 algorithm is an improved ID3 algorithm so that it can handle missing values and continuous data. This study aims to construct a model and analyze the performance of the model obtained using the Decision Tree method with the C4.5 algorithm. In determining the best model, you can utilize Split Validation and k-fold Cross Validation. The best model was obtained in the first iteration of 10-fold Cross Validation. The best model is then used in a web application that can be used by the community to predict the impact of earthquakes that occur in Indonesia.

Abstract

The systematic review literature on the integration of computational thinking in learning mathematics at K-12 mathematics education showed that student-centered teaching approaches can bridge computational thinking and mathematics. However, studies on the role of ICT in improving the quality of learning and the integration of computational thinking in supporting the academic ability of K-12 students are still little reviewed in the current literature. In an effort to fill this gap, a systematic review of the pedagogical role of ICT in asssisting the improvement of students’ computational thinking in K-12 mathematics learning needs to be conducted. This study analyzed 14 studies from the Scopus database that met the inclusion requirements. The PRISMA protocol was used to assess the 14 studies reviewed. The results of this research are that several ICT tools effectively enhance students' CT in mathematics education, including augmented reality, digital gamification technology, robots, tablets, ePCR devices, online platforms for algorithm-based tasks, and problem-based programming. These studies recommend integrating these ICT tools into standard mathematics curricula, with careful design of learning activities, appropriate to students' developmental levels, and supported by adequate teacher training.

Abstract

Geometric thinking level and habits of mind were important hard and soft skills required of prospective mathematics teachers. The purpose of this study is to describe the van Hiele geometric thinking level and habits of mind of prospective mathematics teachers. The descriptive quantitative research method was used. There were 31 female and 17 male prospective mathematics teachers in the sample. The research instrument for measuring geometric level was derived from Usikin's (1982) van Hiele geometric thinking test and a habits of mind questionnaire. According to the findings of this study, prospective mathematics teachers' ability to think geometrically has progressed to the stage of analysis and informal deduction. Furthermore, male prospective mathematics teachers achieved the highest level of geometric thinking, known as rigor. Furthermore, both as a whole and in terms of indicators, prospective mathematics teachers' habits of mind fall into the strong category. Male prospective mathematics teachers have more positive habits of mind than female prospective mathematics teachers. The study's findings can help lecturers, particularly those in the mathematics education study program, determine students' hard and soft skills at the end of the year. Prospective mathematics teachers can also be assigned by institutions based on their geometric thinking and habits of mind.

Abstract

Research on the ontogenic and didactical obstacles vocational high school students face in solving counting rule problems has been limited. Ontogenic obstacles involve students' readiness, while didactical obstacles concern the sequence and presentation of instructional materials. Therefore, teachers must consider both when developing effective materials. This research aims to describe the ontogenic and didactical obstacles experienced by vocational high school students in solving counting rule problems. The participants of this study were 24 grade XII students from a public vocational high school in Cirebon. Using a Didactical Design Research (DDR) approach, this qualitative study focuses on the prospective analysis stage, examining these obstacles. The research instrument included five diagnostic essay questions and interview guidelines. The results revealed that students encountered instrumental-type ontogenic obstacles, particularly in understanding factorial operations. Additionally, didactical obstacles arose from incomplete teaching materials and improper notation, which led to learning barriers. This research offers valuable insights for teachers and researchers in designing instructional materials, especially for counting rules in vocational schools.

Abstract

The emergence of ICT in teaching and learning has contributed to improving the quality of education, because teaching and learning is ultimately an active and interesting process linked to real-world situations. ICT can be integrated into all subjects outside of physical education, including language, comprehension, math, science, and environmental science. This research examines trends and identifies publications concerning ICT in Mathematics Learning by analyzing the most prolific document sources, rankings of institutions or universities, prominent journals and articles, as well as keyword usage. Utilizing data from the Dimensions database, a total of 390 documents were gathered through the Publish or Perish (PoP) application, consolidated into a single RIS file, and analyzed using the VOSviewer application to generate network and overlay visualizations.The findings reveal an increasing trend in publications on ICT in Mathematics Learning over the past five years, with Indonesia leading in the number of documents (66), "Guangxi Normal University" as the top institution, "Journal of Physics: Conference Series" as the most prominent journal, and the article by Lo et al. (2018) as a key reference. The keyword "ICT" is not commonly associated with other variables such as case studies or stems, presenting a gap that offers opportunities for future research in this area.Penggunaan Teknologi Informasi dan Komunikasi (TIK) dalam pembelajaran telah berperan dalam meningkatkan kualitas pendidikan, menjadikan proses pembelajaran lebih aktif, menarik, dan relevan dengan situasi dunia nyata.
