In 2016, there were 4.9 million students identified as English language learners (ELLs) in U.S. public schools who undergo testing. Students identified as ELLs are allowed to use paperback bilingual dictionaries during testing as an accommodation. When deciding whether to provide the accommodation, teachers need to consider several factors. First,…

Prior research shows that self-explanation promotes understanding by helping learners connect new knowledge with prior knowledge. However, despite ample evidence supporting the effectiveness of self-explanation, an instructional design challenge emerges in how best to scaffold self-explanation. In particular, it is an open challenge to design…

Using the "Three Phase Lesson" model, teachers identify prior knowledge that the student must possess in order to be successful in learning the new concepts. Teachers then delineate specific components inherent in the concepts that need to be mastered and identify tasks which will enable the student to practice these new concepts.

The episodic context account of retrieval-based learning proposes that retrieval enhances subsequent retention because people must think back to and reinstate a prior learning context. Three experiments directly tested this central assumption of the context account. Subjects studied word lists and then either restudied the words under intentional…

Animal studies suggest that time delay between acquisition and retrieval of contextual anxiety increases generalization. Moreover, such generalization is prevented by preexposure to the context (CTX), presumably due to an improved representation of such context. We investigated whether preexposure and time-passing modulate generalization of…

The purpose of this article is to examine the qualitative data gathered in a recent survey study of students who completed a prior learning assessment (PLA) portfolio online course in order to inform practice at institutions currently utilizing or considering such a course. PLA programs and system-wide initiatives are proliferating (Klein-Collins…

When presented with a problem in mathematics class, students often function as problem performers rather than problem solvers (Rigelman 2007). That is, rather than understanding the problem, students focus on using an operation to complete it. Students' tendencies to act as problem performers can prevent them from suggesting problem-solving…

Reading research has recognized the strong relationship between vocabulary and reading comprehension. However, we are still perplexed by the precise nature of how readers access and retrieve word meanings while reading. We have not reached a consensus on "what it means to know a word" (e.g., Anderson & Nagy, 1991; Nation, 2001) or…

Globally, school systems are pressed to engage in large-scale school improvement. In the United States and other countries, school district central offices and other local governing agencies often engage with external organizations and individuals to support such educational change efforts. However, initiatives with external partners are not…

This paper demonstrates that the emphasis on students' socioeconomic status (SES) in research and policy circles in Australia is unwarranted. The bivariate relationships between SES and educational outcomes are only moderate and the effects of SES are quite small when taking into account cognitive ability or prior achievement. These two influences…

Two people in the same situation may ascribe very different meanings to their experiences. They will form different awareness, reacting differently to shared information. Various factors can give rise to this behavior. These factors include, but are not limited to, prior knowledge, training, biases, cultural factors, social factors, team vs.…

Digital learning has become an inevitable trend with many benefits for students' learning performance and motivation. However, Virtual Reality, a pervasive mode of digital learning nowadays, has incurred ambivalence among teachers over the years due to its high cost and other technical concerns. Panoramic image VR (PIVR) is a cost-efficient…

There is limited research on the effectiveness of aural versus audiovisual input in incidental second language vocabulary learning (IVL). The current study aims to determine which mode of input, viewing or listening, is more conducive to IVL, and if the level of visual aid for the words leads to a significant difference in word gains. English…

Decades of scholarly work continue to document the marginalization of children from nondominant backgrounds in mathematics classrooms. Learning to equitably teach children from linguistically, ethnically, racially, and culturally diverse backgrounds remains a priority. This dissertation approaches this broader problem in society by understanding…

Making and maker spaces have attracted increasing attention as potential sites for supporting K-12 student learning in science, technology, engineering, and mathematics (STEM) and as a means of competency development for computational and design thinking as well as technological literacy. While interest in making and maker spaces is high, little…
