The U.S. Nation's Report Card reveals that lower performing students exhibited greater achievement decline than their average/high performing peers based on 2022 long-term trend mathematics assessments for age 9 students. Technology, including computer-assisted instruction, plays an important role in today's dynamic learning environments.…

The goal of this dissertation project is to use embodied learning--an emerging approach to supporting student engagement--as a focal point to demonstrate how a multidimensional engagement framework can help us understand, evaluate, and design for new ways of learning. The project is situated in the context of third-grade students learning about…

Developing multiplicative reasoning is an important milestone for elementary school students, which influences their learning of later mathematical concepts (Hackenberg and Tillema 2009). For children to conceptually understand multiplication, one should move beyond merely counting by ones to dealing with composites (twos, fives, etc.) and other…

Traditional museums of culture and history are failing to develop or make effective use of augmented reality (AR) technology. To address this deficit, the present study sought to develop online and offline experiential AR learning tools that would enable children to more fully explore museum artefacts. The study approach was based on the Blended…

Research has shown that a profound place value understanding is crucial for success in learning mathematics. At the same time, a substantial number of students struggles with developing a sustainable place value understanding. In this regard, two aspects of the place value system appear especially relevant: First, the knowledge of the decimal…

This paper examines the roles of multimodality and thematic patterns in the teaching of the particle model of matter. Although the particle model is a fundamental topic in science education, there is no consensus on (1) whether or not the model should be introduced in early grades and (2) how to introduce the model to students for the very first…

The scientists of the future will need to begin studying science to great depth, much earlier in life, in order to keep up with the accelerating pace of discovery and technological innovation. For this to be possible, engaging and child-friendly pedagogical approaches need to be developed that leverage the natural enthusiasm of young science…

The purpose of this longitudinal, mixed methods quasi-experimental study was to investigate the impact of balanced literacy coaching on teacher efficacy, practices, beliefs, and student achievement. The participants were third- through sixth-grade teachers from five elementary schools within the same south suburban Chicago public school district.…

Teacher preparation programs in the US have addressed complex teaching practices, like mathematical discourse, by engaging preservice teachers in the practice of teaching. This qualitative study reports on the nature of conferences about the discourse between an elementary education preservice-inservice pair participating in a model that…

Research suggests that it is challenging for elementary students to develop conceptual understanding of trait variation, inheritance of traits, and life cycles. In this study, we report on an effort to promote elementary students' learning of hereditary-related concepts through scientific modelling, which affords opportunities for elementary…

Learning about heredity is important across the K-12 continuum. However, these ideas may be challenging for students. We examined third-grade students' ideas about heredity in the context of a new, six-week, model-based science unit that uses corn as a model organism to support students' ideas about heredity. We analyzed data collected during…

Serious video games (SVGs) are increasingly used as supplementary teaching tools for mathematics education. Several studies report their positive impact on student learning. However, these impacts are variable, and the success of the tools cannot be generalized or extended to all settings or disciplines without an in-depth look at the games…

This paper considered best practices in teaching culturally and linguistically diverse (CLD) students. A case study research design was used to discover specific English as second language (ESL) strategies teachers are using in their classrooms and specific ESL strategies students find engaging and helpful to learn. This study collected data using…

We present a reconceptualized framework for opportunity to learn (OTL) in school mathematics that builds on previous conceptualizations of OTL and includes features related to both quantity (i.e., time) and quality. Our framework draws on existing literature and on our own observational research of mathematics teaching practices. Through the…

The big idea of "celestial motion", observational astronomy phenomena explained by the relative position and motion of objects in the solar system and beyond, is central to astronomy in primary and secondary education. In this paper, I argue that students' progress in developing productive, scientific explanations for this class of…
