Electronic teaching materials have an important role in improving the quality of learning, making learning more interactive, and making the learning process more flexible and productive. The development of the increasingly sophisticated era, technology, information, and communication have also developed and have an impact on learning media,…

Assessment in education involves collecting and processing information related to student achievement during learning. Assessment activities help educators to find out where learners are having difficulties which for the sake of completeness requires an integrated instrument. The assessment carried out should conform to 21st-century learning…

Background/purpose: The challenges in implementing Indonesia's Merdeka Curriculum highlight the urgency for innovative educational approaches to address gaps in historical knowledge and develop 21st-century skills. This study explores the integration of the Among System into the Merdeka Curriculum framework to foster critical thinking,…

The biological concept has a broad scope and requires the visualisation of bioprocesses to provide complex understanding. Learning media can help visualise bioprocesses to enhance students' cognitive abilities. The study aimed to develop, test the practicality, and test the effectiveness of video animation in improving grade XI high school…

Students' ability in Indonesia has decreased due to the COVID-19 pandemic, so the Government provides solutions to restore learning in Indonesia through a Merdeka curriculum. The impact on schools, especially mathematics subjects, decreased mathematical problem-solving abilities. The decreasing ability of students to solve problems requires a test…

Learning is a process of interaction between students and educators as considerable as learning resources in learning environment. The use of media in learning plays an important role in providing clearer explanation for difficult materials or concepts for students. This research aimed at developing booklet as a biology teaching supplement,…

Biology learning, based on the curriculum-2013, requires students to be skilled at analyzing, evaluating, and creating to achieve Higher-Order Thinking Skills (HOTS). Thus, HOTS assessment instrument is crucial to be made. This study aimed to produce HOTS assessment instrument focused on circulatory system materials for XI graders. This research…

This study aims to evaluate the psychometric properties of the developed diagnostic assessment test and to identify student misconceptions in science in terms of school grades. 153 students were gathered by using random sample from 10th to 12th grade in senior high schools. The 32 items of the two-tier multiple-choice diagnostic test were…

Classical assessments that are not comprehensive and do not distinguish students' initial abilities make measurement results far from the actual abilities. This study was conducted to produce a computerized adaptive test for physics critical thinking skills (CAT-PhysCriTS) that met the feasibility criteria. The test was presented for the physics…
