An amusement park is full of examples that can be made into challenging problems for students, combining mathematical modelling with video analysis, as well as measurements in the rides. Traditional amusement ride related textbook problems include free-fall, circular motion, pendula and energy conservation in roller coasters, where the moving…

For many students, the first--and sometimes only--chance to look through a microscope is in high school biology class, where they observe plant and animal cells up close. Even in college, few students use a microscope for a subject other than biology. Thus, it can be a surprise to learn that microscopes are a primary tool used to understand the…

This paper reports on an interview study of 18 Grade 10-12 students' model-based reasoning of a chemical reaction: the reaction of magnesium and oxygen at the submicro level. It has been proposed that chemical reactions can be conceptualised using two models: (i) the "particle model," in which a reaction is regarded as the simple…

This research is an innovative development on teaching materials in order to intensify the movement of "Satu Guru Satu Buku (SAGUSABU)" and to prepare skillful media users on mastering Information and Communication Technologies (ICT). The resulting prototype is an interactive e-module named Chemistry Magazine which have two editions:…

Despite the role of agency in schools, few researchers have addressed the issue. The present study aims to analyze the relationship between agentic engagement, basic psychological needs, and test anxiety by using structural equation modeling. For this purpose, 289 female students in math-physics and basic sciences were selected as the samples by…

Rigorous and responsive science teaching is based on supporting all students in making progress in their understanding of important science ideas over time. In this article, we explore how did classroom talk patterns of funneling and focusing support student sensemaking. We share how talk, tasks, and tools within classroom activity work together…

This paper presents a descriptive case study where infographics--visual representation of data and ideas--have been used as cognitive tools to facilitate learning with multiple representations in the context of secondary school students' science news reporting. Despite the complementary nature of the two research foci, studies on cognitive tools…

December 26, 2004 was one of the deadliest days in modern history, when a 9.3 magnitude earthquake--the third largest ever recorded--struck off the coast of Sumatra in Indonesia (National Centers for Environmental Information 2014). The massive quake lasted at least 10 minutes and devastated the Indian Ocean. The quake displaced an estimated…

In science education, context-based learning is mostly based on problem-oriented tasks [Gilbert, J. K. (2006). On the nature of "context" in chemical education. "International Journal of Science Education", 28(9), 957-976]. Therefore, a relevant question is, how do students integrate the information given in the task into their…

This article is the second of a two-part series that explores science teachers' and their pupils' experiences of using different pedagogical approaches based on understandings of how brains learn. Part 1 (Torrance Jenkins, 2017) focused on the two approaches rooted in cognitive psychology: Cognitive Load Theory (CLT) and Cognitive Acceleration…

The article explores the motivation of Thai secondary school students who chose to enroll in private tutorial institutes. The research draws on primary qualitative data compiled from structured interviews utilizing a comparative perspective to provide insight into perceptions of tutorial versus formal secondary education. The evidence presented…

The study of vibration in uniform beams provides physics teachers with a platform by which a broad range of physics vibration-related topics can be explored without expensive and specialized equipment. This paper presents two laboratory exercises related to lateral beam vibrations. These exercises use beam theory coupled with free sound-analysis…

This research investigates various purposes of teacher discourse moves essential to orchestrate dialogic discourse in secondary science classrooms. Data collected includes classroom observations and teacher interviews of two teachers teaching in an Indian school setting, whose classroom practices subscribed to a dialogic framework. A discursive…

Teaching socio-scientific issues (SSIs) allows students to explore science ideas and practices intertwined with complex social phenomena, which can promote significant growth in critical thinking. Sadler, Barab, and Scott (2007) suggested specific critical thinking competencies associated with the negotiation of SSIs that capture the complexities…

This article presents the findings of an ethnographic interview study that examined the ways students experienced a justice-centered AP chemistry course at an urban neighborhood high school. Justice-centered science pedagogy is an approach to teaching science that treats inequity in science education as one component of larger systems of…
