Background: Computational thinking (CT) refers to the ability to represent problems, design solutions and migrate solutions computationally. While previous studies have shown that self-explanation can enhance students' learning, few empirical studies have examined the effects of using different self-explanation prompts to cultivate students' CT…

Background/purpose: Differentiated teaching materials are a source of quality and meaningful learning for students because they are prepared based on students' needs. Materials/methods: This research includes development research using the ADDIE model which aims to describe the profile of digital-based differentiated teaching materials (Barista)…

After years evaluating teacher professional learning programs, researchers Andrew J. Wayne, Jordan Rickles, Mengli Song, Seth Brown, and Michael S. Garet describe a study that changed their perspective. The study's takeaways about the design of teacher professional learning are important for everyone who seeks to create systems to support teaching…

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…

Introduction: In this paper, we present how seventh-grade students become aware of rational numbers during mathematics instruction through the social process of objectification when comparing two magnitudes. Methods: Theoretical elements of the Theory of Objectification and the Onto-Semiotic Approach to Mathematical Instruction and Cognition guide…

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"…

Problem-solving ability was one of the competencies that students had to have, but it became more important when learning mathematics. Quite a lot of research has studied this ability, but not much has studied how to optimise it, especially using didactical design research based on lesson study. Participants in this research were 10 students…

Virtual reality is a rapidly growing technological innovation that continues to garner attention for use in education. This self-study of two teacher educators spans immersive head-mounted virtual reality implementation from 2014-2023 with middle-grades students, preservice teachers, and adult learners. Empirical data sources include learner…

The aim of the study informing this paper was to investigate pre-service teachers' (PSTs') approaches to task design, posing the research question: How do pre-service teachers respond when they are asked to design an exploratory task using GeoGebra for 8th grade students? The research study and this paper focus on the PSTs' design stories rather…

Instructional designs that include two or more artifacts (digital manipulatives, tables, graphs) have shown to support students' development of reasoning about covarying quantities. However, research often neglects how this development occurs from the student point of view during the interactions with these artifacts. An analysis from this lens…

The COVID-19 pandemic has created an opportunity for K-12 schools to rethink and redesign instruction. The urgency to continue providing students with education accelerated the blend of face-to-face instruction and online learning in K-12 education. Blended learning is any formal education program that combines face-to-face instruction with online…

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…

Many students rely on rote algorithms that have been recently taught as they look for a direct way to tackle challenging problems. Especially for students who have not succeeded in the typical high-school curriculum, problem-solving in a novel situation is complex, and students ask for a direct way to solve rather than persevering. The purpose of…
