Using a verbal protocol, this study investigated how 38 second-grade students identify, describe, and interpret five types of commonly used visual graphics in science texts (i.e., cut-away diagrams, maps, captioned photographs, flow diagrams, and hybrids). Additionally, we explored the challenges students encountered when interpreting these…

Background: This dissertation examines the pervasive influence of the white and colonial imaginary in shaping educational narratives that promote neoliberal success and capitalism, impacting the minds of successive generations. Contemporary youth perceive these narratives as detrimental, contributing to racial violence, climate-induced…

This dissertation investigates how embodied learning within a Mixed Reality (MR) environment supports young children's science learning, focusing on a honeybee system. To do so, I designed three types of activities within an MR environment to enable young children to assume different perspectives as they create embodied models of honeybees as…

Research has consistently highlighted the importance of promoting child-parent interactions. In this essay, we describe the development of MAKEngineering kits that provide collaborative learning experiences for children in Grades 2-6 to engage in engineering design tasks with members of their families in their home environment. First, we present…

In this qualitative, descriptive case study, we examine how elementary emergent bilinguals (EBs) use disciplinary language as they engage in integrated science and engineering instruction. Instruction incorporated language and developmental scaffolds corresponding to EBs' language and content learning needs. Oral production of EB kindergarten to…

Following a theoretical framework that recognizes the potential of promotive and inhibitive effects on children's development, this study explored child-, family-, classroom-, and school-level factors as predictors of Latinx (N = 4,590) students' early elementary science achievement. Research Findings: Employing a path modeling approach with…

It is urgent to ensure that science, technology, engineering, and mathematics (STEM) education meets the needs of our nation's increasingly diverse student population. This study examined whether a second-grade science program, Scientific Explorers, supported educational equity in STEM achievement for diverse student populations. Sociodemographic…

This mixed-methods study explores the relationship between early elementary students' domain-specific vocabulary knowledge and their ability to comprehend grade-level reading passages on unfamiliar science topics. Specifically, this study used (a) structural equation modeling (SEM) to examine the extent to which students' networks of…

Owing to its recognition as a 21st-century skill, computational thinking (CT) is currently being introduced into school curricula around the world. However, in-service teachers are largely unprepared for this implementation, which, in turn, makes teacher educators (TEds) important stakeholders in preparing prospective teachers to integrate CT into…

Within the field of K-2 computer science (CS) education, unplugged computational thinking (CT) activities have been suggested as beneficial for younger students and shown to impact young students' skills and motivation to learn about CS. This study sought to examine how children demonstrate CT competencies in unplugged sequencing tasks and how…

We investigated the effectiveness of a sustained and spiraled content literacy intervention that emphasizes building domain and topic knowledge schemas and vocabulary for elementary-grade students. The model of reading engagement intervention underscores thematic lessons that provide an intellectual structure for helping students connect new…

Nanoscience and Nanotechnology (NST) education is at the forefront of an emerging interdisciplinary frontier, ready to address global challenges. In this context, our research adopts a distinctive approach--using software applications in digital games to introduce young children to NST concepts and analyse resulting learning outcomes. The…

Primary school children frequently use digital devices, which can be infected by computer viruses. In this mixed methods paper with two studies (N = 278 + 114), we examined 8-year-olds' preconceptions about computer viruses and protection against them; how to teach these children about said topics using three different, 30-min-long,…

Computer Science (CS) is a rapidly growing field that impacts almost every aspect of students' lives. From media consumption to future careers in medicine, agriculture, security, finance, and other areas, understanding computer programming is essential for 21st-century society and careers. Over the next decade, employment opportunities in computer…

This dissertation investigates the issue of gender stratification within engineering and other STEM-related fields. The dissertation is divided into three articles that address different aspects of the problem and propose potential solutions. Article 1 explores the persistent gender imbalance within STEM fields, particularly in engineering and…
