Background: Despite the numerous positive effects of augmented reality (AR) on learning, previous research has shown ambiguous results regarding the cognitive demand on the learner arising from, for example, the overlay of virtual elements or novel interaction techniques. At the same time, the number of evidence-based guidelines on designing AR is…

Although research indicates that deliberate practice is indispensable for achieving high levels of proficiency and expertise in a range of disparate fields, this type of practice has largely been overlooked in the second language acquisition literature. To bridge this gap, and advocating for a more intentional and goal-directed approach to second…

This book argues that mathematical challenge can be found at any level and at every age and constitutes an essential characteristic of any mathematics classroom aimed at developing the students' mathematical knowledge and skills. Since each mathematics classroom is heterogeneous with respect to students' mathematical potential, quality…

There is extensive empirical research on principles of effective teacher professional development (PD). However, teachers' expectations of PD and how well these align with scientific recommendations are only rarely addressed. N = 125 teachers were presented with video vignettes on two evidence-based interventions of varying complexity for which…

Students with chronic and complex medical conditions often require assistive technologies in order to accommodate both physical and cognitive needs. Survivors of childhood cancer who are eligible for special education offer a lens through which to examine barriers to assistive technology assessment, acquisition, use, and support for students with…

Teaching practices that are aligned with how students learn improve educational outcomes for all students. Empirical evidence gained over recent decades has provided important new insights about the learning process common to students across learning contexts. These processes explain why some teaching practices are more effective than others. In…

This study reports on an Evidence Centered Design (ECD) project in the Netherlands, involving the theory exam for prospective car drivers. In particular, we illustrate how cognitive load theory, task-analysis, response process models, and explanatory item-response theory can be used to systematically develop and refine task models. Based on a…

The purpose of the current article is to describe a set of empirically validated principles of practice with the potential to enhance student learning and academic performance. Specifically, we provide an overview of Syfr Learning's principles of practice -- a collection of scalable instructional techniques derived from decades of research in the…

Authentic assessment is revered to support student learning, but it is typically described within the context of work-integrated learning and professional schools, leaving one to question whether a classroom-based curriculum can offer authentic assessments. This study documented the prevalence of authentic assessments throughout a complete health…

Preverbal communication means any social behavior that occurs before children communicate verbally. Generally, these communicative behaviors are categorized into two ways: as behavior regulation (BR) or joint attention (JA) skills. BR, also referred to as requesting, involves the use of behaviors to gain something or receive assistance (Mundy et…

While AI has become more prevalent in our society than ever, many young learners are found holding various naive, erroneous conceptions of AI due to the influence of their technology and media environments. To address this issue, this study seeks to propose a novel pedagogical solution to improve upper-elementary school students' scientific…

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) non-traditional…

This dissertation investigates how English-speaking second language (L2) learners of Mandarin perceive, process and learn Mandarin lexical tones. While most languages use modulations in pitch (intonation) to convey meanings at the phrasal and sentential levels, a number of languages, including Mandarin, also use suprasegmental features such as…

A solid foundation in fractions is a key predictor of success in algebra and more advanced mathematics, which in turn is predictive of entry into higher education and many high-paying vocations. Yet, when fractions are introduced into the mathematics curriculum in upper elementary grades (grades 4 and 5), many students demonstrate minimal growth…

Mid-20th-century scholars argued that second language (L2) instruction should be rooted in a comparison of the structural characteristics of the first language (L1) and L2. Their enthusiasm for a "scientific" approach to errors reflected the view, based on the contrastive analysis hypothesis (CAH), that learners' difficulties could be…
