Life in the twenty-first century requires education to integrate knowledge, attitudes, skills, and mastery of information and communication technology (ICT). An example of the skills needed in the twenty-first century is computational thinking. This study aims to develop computational thinking-skill tasks on numbers and arithmetic based on the…

Self-proficiency, distinct from self-efficacy, is a more comprehensive dimension in assessing students' abilities. Moreover, the TAI cooperative learning model is believed to be relevant in enhancing self-proficiency, as well as other mathematical ability dimensions, particularly in Statistics course. Therefore, this study aimed to assess the…

In the virtual laboratory learning process, students' scientific abilities in solving a problem are very important to explore. This study aims to develop classroom-based authentic assessment instruments through virtual laboratory learning in chemistry to see an increase in students' scientific performance. The research was conducted at a public…

The purpose of the present study is to provide empirical evidence on the adaptation of the mathematics-related beliefs questionnaire (MRBQ) supplemented by info-communication technology-related items. Besides, we also investigate the relationship between their beliefs about mathematics and their ability in problem-solving mathematics. 234 grade…

The purpose of the study was to develop an instrument for the problem solving ability of students in Hybrid learning by Ethno-STEM via Four-D Model.

This research goal to develop a multiple-choice closed-ended test to assessing and evaluate students' digital literacy skills. The sample in this study were students at MTsN 1 Blitar City who were selected using a purposive sampling technique. The test was also validated by experts, namely 2 Doctors of Physics and Science from Yogyakarta State…

This cross-sectional study aimed to validate students' metacognition awareness inventory in Heat and Temperature material. A total of 167 public senior high school students in Yogyakarta, Indonesia were selected through convenience sampling technique. The heat and temperature metacognition awareness inventory (HeTMAI) inventory consists of six…

The accuracy of learning results relies on the evaluation and assessment. The learning goals, including problem solving ability must be aligned with the valid standardized measurement tools. The study on exploring the nature of problem-solving, framework, and assessment in the Indonesian context will make contributions to problem solving…

This study aims to develop and validate a scale to measure student academic resilience on junior high school level. The sample in this study was 865 junior high school students spreading across various regions in Indonesia. The methodology used in this research was quantitative, using a questionnaire with a 4-point Likert scale. The data analysis…

This study aims to describe: (1) The validity and reliability of the PISA model mathematical problems on the change and relationship content developed; (2) The practicality of PISA mathematical problem models on the developed change and relationship content; (3) Students' mathematical problem-solving abilities on mathematical problems in the PISA…

The purpose of this research is to develop test questions of problem solving ability on work-energy material for high school students class X. This type of research is research and development. The model used in this study is ADDIE with the stages of analyzing, planning, developing, implementing, and evaluating, but this study only up to the…

The ability to think critically and creatively is essential for students to help them thrive in the 21st century. Creative and critical thinking can be measured through problem solving because the assessment contains tasks that require students to find problems, analyze and evaluate problems, and work out the solutions. Therefore, this study was…
