Based on the data analysis, it can be concluded that there are still limited realistic problems in Indonesian mathematics textbook for vocational high school based on each expertise fields. Therefore, developing an integrated RME and PBL mathematics e-module is necessary. The characteristic of the integrated RME and PBL mathematics e-module are: (1) the e-module’s content should be presented in Bahasa Indonesia, providing realistic contexts by the certain expertise field and can also be from various expertise fields; (2) the learning activities should be carried out in groups, held inside or outside the classroom and involve problems that are related to the expertise field; (3) the learning media can be in the form of electronic and non-electronic media; (4) The assessment activities can be carried out in writing or authentic assessment.

To create an interactive learning atmosphere in the classroom, one way is to use game media that is integrated into learning. There have been many efforts to develop monopoly game media in mathematics learning. However, no research has been found that attempts to develop monopoly game media in mathematics using a learning approach that involves students. Therefore, this research aims to describe the development of monopoly game media on rolling question-based algebra material and analyze the validity and practicality of the media. The development model used in this research is the ADDIE model, an acronym for Analysis, Design, Development, Implementation, and Evaluation. The subject of this research was a class of private junior high school students in Surakarta. The data collection technique uses a response questionnaire obtained from expert validators, teachers, and students. The collected data is then analyzed to determine the validity and practicality of the media that has been developed. The results of data analysis provided by media expert validators obtained an average percentage of 97.6%, while data obtained from practitioners showed an average percentage of 85.6%. Based on the results of this research, it was concluded that the algebra monopoly game media based on rolling questions was declared valid and practical for use as a mathematics learning media in junior high school algebra material.

Virtual reality (VR) is an innovative technology that immerses users within its environment, holding significant potential across various sectors, including education. Developing a VR-based application in the form of a game for educational purposes necessitates a usability evaluation. This study aims to develop and evaluate the usability of a VR game, CT Saber, designed explicitly for learning computational thinking (CT). The name CT Saber is inspired by the popular VR game Beat Saber, with 'CT' denoting computational thinking to emphasize the educational focus of the game. The research employed a Design and Development Research (DDR) approach, encompassing four stages: analysis & definition, design, development, and evaluation. To assess the usability of CT Saber, pilot testing was carried out involving 36 participants (24 male, 12 female) of computer science students aged between 19-22 years. The USE Questionnaire framework was used to evaluate usability, consisting of four variables: usefulness, ease of use, ease of learning, and satisfaction. The evaluation revealed that CT Saber is categorized as 'acceptable' from dichotomous and conventional academic grading perspectives. Similarly, a multiple linear regression analysis confirmed that the independent variables (usefulness, ease of use, and ease of learning) together significantly (p < 0.01) influence the dependent variable (satisfaction). However, only usefulness significantly influences satisfaction. Responses to open-ended questions in the questionnaire also indicated predominantly positive feedback from most participants. Consequently, it can be concluded that the CT Saber VR game developed in this study successfully meets the established criteria for usability.

In the digital age, where programming prowess is increasingly crucial, the enhancement of Computational Thinking (CT) skills becomes essential. This study ventures into the scarcely explored domain of leveraging game-based learning (GBL) within virtual reality (VR) settings to bolster CT skills. Specifically, it introduces "CT Saber," a VR game inspired by the popular "Beat Saber," tailored to cultivate CT competencies. Employing a Design and Development Research (DDR) methodology across five stages—analysis, design, development, implementation, and evaluation—this investigation assessed the game's impact on 37 computer science students (25 male, 12 female) aged 21-24. A quasi-experimental design with pretest-posttest evaluation was utilized, revealing significant enhancements in CT skills post-intervention (Z = -4.496, p < 0.05), as analyzed through Wilcoxon Signed-Rank tests. The findings underscore the VR game's efficacy in CT skill development, suggesting a promising direction for integrating VR technologies in programming education.
