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"…

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…

It is widely argued that Nanoscience and Nanotechnology (NST) is going to affect several aspects of our life. Therefore, students need to develop their nanoliteracy to cope with the everyday issues related to NST. Although there is an increasing interest in introducing NST content to primary school students, the theoretical frameworks for…

Students need to be actively engaged to learn--intellectually curious, physically active, and emotionally involved in collaborative work that builds their capacity for empathy. What can teachers do to instill these elements in the classroom? "Active Learning: 40 Teaching Methods to Engage Students in Every Class and Every Subject" is the…

Employing a statistical modeling inspired pedagogy is becoming a widespread practice in the statistics education community. Many have incorporated the practice of formulating conjectures in their modeling-enhanced educational designs and have reported on its benefits. We further elucidate the mechanism through which students' conjecturing may be…

This study introduces a novel learning management model aimed at enhancing Thai language proficiency in sixth-grade students. Confronting challenges such as inadequate teaching resources and a lack of student-centric, practical activities in current Thai language education, this model integrates six key components: foundational principles and…

Integrating mathematics content into science usually plays a supporting role, where students use their existing mathematical knowledge for solving science tasks without exhibiting any new mathematical meanings during the process. To help students explore the reciprocal relationship between math and science, we designed an instructional module that…

Student Uncertainty as Pedagogical Resource (SUPeR) is a teaching approach that science teachers can use to promote student scientific literacy, practice, and learning. SUPeR helps students navigate scientific uncertainty to improve understanding of scientific concepts and phenomena. The SUPeR approach consists of four phases: (1) problematize a…

The frequentist and classical models of probability provide students with different lenses through which they can view probability. Prior research showed that students may bridge these two lenses through instructional designs that begin with a clear connection between the two, such as coin tossing. Considering that this connection is not always…

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 dissertation is rooted in three strands of scholarship: translingual approaches to writing (Horner et al., 2011), social design-based experiments (Gutierrez & Vossoughi, 2010) as a subset of participatory design-based research (Bang & Vossoughi, 2016), and the Learning on the Move framework centering embodied and mobile epistemologies…

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…

Around the world, programming education is actively promoted by such factors as economic and technical requirements. The use of a robot in programming education could help students understand computer-science concepts more easily. In this study we designed a course in programming a robot for elementary school students and investigated its…

Historically, learning for young students has occurred in formal, in-person classroom environments. But in just a matter of weeks, children were mandated to transition to a completely new mode of learning, facing new learning challenges with heightened anxieties. To this end, we aim to better understand how our learning experience design (LXD)…
