There is growing interest in the introduction of Einsteinian concepts of space, time, light and gravity across the entire school curriculum. We have developed an educational programme named 'Einstein-First', which focuses on teaching Einsteinian concepts by using simple models and analogies. To test the effectiveness of these models and analogies…

The aim of this research was to assess the classification of science test items of TIMSS grade 8 based on higher order thinking skills (HOTS) and determine whether those classified-science test items can be an assessment tool in science class. Sixteen sample test items of HOTS were chosen from 37 reasoning items of TIMSS 1999, 2003, and 2011;…

This paper describes a curriculum-based multidimensional computerized adaptive test that was developed for Indonesia junior high school Biology. In adherence to the Indonesian curriculum of different Biology dimensions, 300 items was constructed, and then tested to 2238 students. A multidimensional random coefficients multinomial logit model was…

This study aims to test the effectiveness of a socio-scientific issue (SSI) based instruction through STEM-6E (engage, explore, explain, engineer, enrich, and evaluate). Controversial science topics (e.g. genetically modified organisms) in many countries, especially Indonesia, can be approached via integrated STEM education. One hundred and nine…

The purpose of this study is to develop scientific literacy evaluation instrument that tested its validity, reliability, and characteristics to measure the skill of student's scientific literacy used four scientific literacy, categories as follow:science as a body of knowledge (category A), science as a way of thinking (category B), science as a…

The aims of this study are: (1) to investigate the level students' critical thinking skill on living things and environmental sustainability theme, (2) to examine the critical thinking difference among gender, learning styles, and students' motivation, and (3) to investigate the correlation between students' critical thinking and students'…
