This study explored the effects of explicit and implicit epistemologically enhanced instructions probing 9th-grade students' personal epistemologies on their physics-related personal epistemology (PPE) and physics achievement in the heat and temperature unit. In the implicit epistemologically enhanced instruction (IEEI), different dimensions of…

This study aims (1) to develop an instructional model to enhance mathematical literacy for secondary students and (2) to examine the effects of using this instructional model. The sample group consisted of students from Lampabpla Wittayakarn School, under the jurisdiction of the Surin Secondary Educational Service Area Office in Thailand by using…

This article reports on the design and implementation of a didactic sequence in the frame of a design-based research study. The research aim is to test the hypothesis that affordances of dynamic geometry may support students' awareness of logical relationships between geometrical properties of constructed figures. We elaborate on the task design…

Mathematical concepts have been a consensus goal for decades, yet there is little consensus on what is meant by the terms "mathematical concept" and "mathematical understanding." This article attempts to discuss these terms in a way that can be of practical use to teachers. Greater clarity on "mathematical concept"…

This paper provides an experience report on a co-design approach with teachers to co-create learning analytics-based technology to support problem-based learning in middle school science classrooms. We have mapped out a workflow for such applications and developed design narratives to investigate the implementation, modifications and temporal…

Theorizing and exploring teacher learning contexts is critical to understanding reform-based instructional changes. Research on professional learning, organizational contexts, and science reform has grown over the years, particularly since the unveiling of the Framework for K-12 Science Education in the United States. In this article, the authors…

There is growing theoretical and empirical consensus for a role of awareness of suprasegmental phonology, also known as prosody, or the rhythmic elements of speech, in reading comprehension. Here we explore a potential mechanism by which this relation functions: awareness of how punctuation reflects prosody, for instance appreciating that a period…

This paper articulates an approach to incorporating instructor feedback in design-based research. Throughout the process of designing and implementing curriculum to support middle school students' debugging practices in a summer computer science workshop, our research and practice team utilized instructor-generated conjecture maps as boundary…

Over the last three years, there have been changes in education such a curriculum, culture, and purpose that has encouraged educators to become more collaborative and modify traditional classroom method of one educator working in isolation to a more team-teaching process. The purpose of this study was to investigate the experiences of teachers…

Climate change in coastal areas is a complex problem that involves value systems and requires various scientific disciplines. Integration of Science, Technology, Engineering and Mathematics (STEM) approach is needed in learning so that it can train students to think holistically, structured and systematically. This research was carried out with…

This study examines an urban middle school teacher design team's capacity for creating integrated science, technology, engineering, and mathematics curricula. Using Brown's pedagogical design capacity (PDC) theory, which highlights interactions between personal and curricular resources, this paper introduces an extended framework that includes…

The aim of this study is to design various instructional materials to teach biological systems in a 'Systems in Our Body' unit to 6th grade students with visual impairment (SVI) and to evaluate the effectiveness of these materials. In the study, a design-based research model was used. In the first stage, individual learning needs of SVI and their…

Many studies use instructional designs that include two or more artifacts (digital manipulatives, tables, graphs) to support students' development of reasoning about covarying quantities. While students' forms of covariational reasoning and the designs are often the focus of these studies, the way students' interactions and transitions between…

This paper introduces a model built upon the Method of Varying Inquiry, offering a didactical approach to problem posing and solving activities that stimulates inquiry-based learning in mathematics classrooms. The model combines the inquiry-based framework with the variation theory and with specific didactical and theoretical elements (the…

In this paper, we discuss what creativity may look like in the science classroom and what we learnt from teaching with student-generated diagrams to promote creativity in Year 7 Science lessons. As a result of this study, most students were able to communicate a deeper understanding of complex phenomena and were able to apply this knowledge both…
