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…

Asynchronous, online mathematics teacher professional development (PD) was designed to align with research on teacher professional learning as well as to support Communities of Inquiry (e.g., Garrison et al., 2000). The intervention included two actively facilitated formats and a structured independent condition, where facilitation was integrated…

Innovative learning media are very important in supporting the learning process, including learning Arabic. Therefore, this study aims to develop video media for learning speaking skills as a medium for learning speaking skills for seventh grade students at MTS Negeri 39 Jakarta. The research was conducted using the Research and Development…

Learning progressions have become an important construct in educational research, in part because of their ability to inform the design of coherent standards, curricula, assessments, and instruction. In this paper, I discuss how a learning progressions approach has guided our development of an early algebra innovation for the elementary grades and…

In this paper, we explore how students' algebraic noticing's and explanations changed across a two-year period with the introduction of designed instructional material. The data in this report is drawn from n=53 Year 7-8 students' responses to a free-response assessment task across two different years. Analysis focused on how students noticed and…

Historically, learning for young students has occurred in formal, in-person classroom environments, but the distance learning context has opened a myriad of learning modalities. To this end, we aim to better understand how deploying learning experience design (LXD) approach supports or hinders children's engagement while participating in an…

This study is introducing the basic principles of Engineering Pedagogy Science for effective design, teaching and learning of science, technology and engineering. The basic didactical models are introduced for contemporary design of effective teaching and learning. A quadruple instruction model of Engineering Pedagogy Science is proposed,…

This study investigates the use of manipulatives by elementary students working on a fraction task. Extending previous work on the role played by the manipulatives in students' activity, we aim at describing how the choices made for the task design disrupt students' activity, creating opportunities to learn. The theoretical underpinnings allow…

This study employed a single factor experiment to investigate how different voices from a social robot affect the learning outcomes and motivation of 46 children. The learning motivation for the participants was measured using the ARCS questionnaire, which tested for four subcategories: attention, relevance, confidence, and satisfaction. The…

This paper describes the first stages on the development of a design method of digital trainings using the collaborative authoring tool "ALO". Based on the theory of instrumental conflict (Marquet, 2005), this method highlights the necessity of the design digital trainings under the optimal harmonization for users/learners in didactic,…

Educational chatbots promise many benefits for teaching and learning. Although chatbot use cases in this research field are rapidly growing, most studies focus on individual users rather than on collaborative group settings. To address this issue, this paper investigates how chatbot-mediated learning can be designed to foster middle school…

This report documents how one undergraduate student used set-based reasoning to reinvent logical principles related to conditional statements and their proofs. This learning occurred in a teaching experiment intended to foster abstraction of these logical relationships by comparing the predicate and inference structures among various proofs (in…

In the light of an educational emergency aggravated by the health emergency following the COVID-19 pandemic, the DELTA (Digital Education for Learning and Teaching Advances) Research Group developed four open online courses available to lower secondary school students and teachers. The four courses, devoted respectively to Numbers, Space and…

This paper describes how an Immersive Virtual Reality (VR) Classroom in a secondary school in Singapore is used to enhance learning through visualization and deepen understanding of science and increase interest and enjoyment in science. The VR Classroom is a futuristic classroom that taps the affordances of VR and AR to enhance HCI…

The domain of motion or kinematics is important because it forms the basis of mechanics, an important branch of physics. By studying kinematic phenomena in the laboratory, high school students are likely to develop a better understanding of kinematics concepts as well as elements of the scientific approach to study natural and constructed…
