Many modern anatomy curricula teach histology using virtual microscopes, where students inspect tissue slices in a computer program (e.g. a web browser). However, the educational data mining (EDM) potential of these virtual microscopes remains under-utilized. In this paper, we use EDM techniques to investigate three research questions on a virtual…

Mathematical calculations are an important part of chemistry. Those problems are difficult for students, especially if the task is set with a limiting reactant. The aim of this study was development of a Procedure for evaluation of cognitive complexity of the Stoichiometric Tasks with a Limiting Reactant. The procedure created included an…

This dissertation consists of three projects that were designed to investigate collegiate instrumentalists' practice habits and motivation orientations. The first investigation was a review of the literature about instrumental practice strategies, motivation orientations, and social factors influencing music practice. The second investigation was…

Agriculture organization (AO) members are key stakeholders within the agriculture and natural resources (ANR) sector, and their engagement in policy decisions can help direct future policy formulation and implementation. Such policies and regulations are often determined by and voted upon by elected officials, and, therefore, the decisions made by…

A great deal of research has focused on tasks, particularly for adult second language learners. In this paper we provide an account of studies that have investigated children and tasks -- an age group that have received far less attention. We consider, in particular, the impact of tasks on children's language learning, how their design features…

Speech planning is a sophisticated process. In dialog, it regularly starts in overlap with an incoming turn by a conversation partner. We show that planning spoken responses in overlap with incoming turns is associated with higher processing load than planning in silence. In a dialogic experiment, participants took turns with a confederate…

Interleaving examples of to-be-learned categories, rather than blocking examples by category, frequently enhances category induction. The presently dominant theory is that interleaving promotes discriminative-contrast, and suggests that category similarity structure modulates this interleaving benefit: that blocking should benefit learning when…

Prospective memory (PM) performance suffers when individuals collaborate, consistent with findings of "collaborative inhibition" in episodic recall. However, prior research indicates strong individual differences, such that some collaborative groups are more effective than others. To identify successful and unsuccessful collaborative…

Probabilities tend to become an integral part of early childhood mathematics curricula. Research has shown that at the age of 4, children indicate basics of probabilistic reasoning and can engage with probabilistic tasks and uncertainty. The aim of this study is to examine whether methodological and design alterations influence children's…

The use of logic is an integral part of mathematical reasoning and communication. This exploratory study explored the reasoning by 122 science students from a university in Lesotho about the truth or falsity of conditional statements. Written tasks and interviews were used as methods of data collection to produce qualitative data. The tasks…

Empirical studies of creativity emphasize the importance of ambiguity advantage in idea generation and creative problem-solving. This study examined whether ambiguous figures could directly induce a mind-set that would transfer to the creative problem-solving. In Experiment 1, we examined whether presentation of ambiguous figures would influence…

Effective self-regulated learning in settings in which students can decide what tasks to work on, requires accurate self-assessment (i.e., a judgment of own level of performance) as well as accurate task selection (i.e., choosing a subsequent task that fits the current level of performance). Because self-assessment accuracy is often low,…

This article provides six fundamental steps for using a task analysis to teach emergent literacy skills to young learners with autism spectrum disorder (ASD). Compared to general education peers, students with ASD score lower on reading measures and often have difficulty acquiring literacy skills via the instruction methods used in typical…

"Natural language understanding" (NLU) of text is a fundamental challenge in AI, and it has received significant attention throughout the history of NLP research. This primary goal has been studied under different tasks, such as Question Answering (QA) and Textual Entailment (TE). In this thesis, we investigate the NLU problem through…

Systems of equations are an important topic in school mathematics. However, there is limited research examining productive ways of supporting students' understandings of systems of equations. In this paper, we first present a conceptual analysis of potential ways students may leverage their quantitative and covariational reasoning to graph systems…
