With the growing prevalence of mobile apps for self-directed learning, educational games increasingly find their place in everyday routines, becoming accessible to a broad audience. Despite the growing ease of content creation by artificial intelligence computing, the challenge of designing effective and engaging Serious Games remains,…

In elementary mathematics instruction, teachers often compromise access and cognitive demand in pursuit of one or the other. I explored how five different co-teaching models impact students' access to cognitively demanding mathematical learning opportunities (MLOs) in elementary classrooms. Through ethnographic lesson observations, artifact…

Australia-wide consensus was reached on seven core concepts of physiology. The "movement of substances" core concept with the descriptor "the movement of substances (ions or molecules) is a fundamental process that occurs at all levels of organization in the organism" was unpacked by a team of three Australian physiology…

Linking assessment and curriculum in science education, particularly within the topic of matter and its changes, is often taken for granted. Some of the fundamental elements of the assessment, such as the choice of wording and visual representations, as well as its relation to the curricular sequence, remain understudied. In addition, very few…

Despite the importance of child assessment data in early childhood education, teachers struggle with its use in their work. This study uses an implementation science approach to explore facilitators and barriers to teacher use of child assessment practices in three Head Start centers and tests a specific strategy to improve teacher practice. This…

Cognitive load is the effort needed to process and store information in memory and can be measured via subjective, physiological, and performance methods. Virtual reality learning environments (VRLEs) enhance science aptitude and motivate students to pursue science careers. Cognitive load is divided into three types: intrinsic, extraneous, and…

Due to the ever-increasing leveraging of technology in learning and human performance, multimedia e-learning continues to see rapid adoption as an instructional method for both business and formal education environments. Cognitive load theory (CLT) and the cognitive theory of multimedia learning (CTML) provide prescriptive strategies to optimize…

Collaborative problem solving (CPS) is inherently an interactive, conjoint, dual-strand process that considers how a student reasons about a problem as well as how s/he interacts with others to regulate social processes and exchange information (OECD, 2013). Measuring CPS skills presents a challenge for obtaining consistent, accurate, and reliable…

This study examined the independent effects of working memory (WM) and the interactive effects of WM/L2 proficiency and WM/task complexity on L2 written performance. The study followed a within--between-participant factorial design, with two levels of task complexity as the within-participant variable and L2 proficiency and WM as…

Access to the college readiness curriculum has become a civil rights issue. Social class continues to impact those underrepresented on college campuses. This dissertation study aims to gain foundational knowledge that can be used to take action by developing recommendations that support a culture in which students from an economically…

We propose a plan to facilitate the development of backward constituent skills within a complex learning process through the manipulation of emphasis sequencing. To achieve this, we utilized perceptual offloading cues as supportive information in emphasis sequencing, taking into consideration principles of information processing and cognitive…

A vast majority of elementary students struggle with the core, pre-algebraic concept of mathematical equivalence. The Improving Children's Understanding of Equivalence (ICUE) intervention integrates four research-based strategies to improve outcomes for second grade students: (1) introducing the equal sign before arithmetic, (2) nontraditional…

Metacognitive awareness is knowing about learners' own thinking and learning, facilitated by introspection and self-evaluation. Although metacognitive functions are personal, they cannot be explained simply by individual conceptions, especially in a collaborative group learning context. This study considers metacognitive awareness on multiple…

Catalysis is an essential concept in chemistry, playing a key role in industrial processes. Catalysis has been considered to be challenging not only for university students to comprehend but also for the teachers. In this Laboratory Experiment, we have described a simple activity for demonstrating the concept of catalysis using thread-based…

Why do people shift their strategies for solving problems? Past work has focused on the roles of contextual and individual factors in explaining whether people adopt new strategies when they are exposed to them. In this study, we examined a factor not considered in prior work: people's evaluations of the strategies themselves. We presented…
