In the age of artificial intelligence (AI), trust in AI systems is becoming more important. Explainable recommenders, which explain why an item is recommended, have recently been proposed in the field of learning technology to improve transparency, persuasiveness, and trustworthiness. However, the methods for generating explanations are limited…

Drawing on research in mathematics and science education that has supported student higher-level thinking in K-12 classrooms, we sought to classify the ways of thinking and reasoning supported by robotics coding tasks. As part of a larger project, we examined coding tasks implemented in elementary school classrooms and analyzed ways of thinking…

In recent years, there has been a strong push to transform STEM education at K-12 and collegiate levels to help students learn to think like scientists. One aspect of this transformation involves redesigning instruction and curricula around fundamental scientific ideas that serve as conceptual scaffolds students can use to build cohesive knowledge…

Young children often make pragmatic assumptions when learning new words. For example, they assume that a speaker who uses different words intends to refer to different things -- the so-called principle of contrast. We used a standard disambiguation task to explore whether children's assumptions about contrast depend on how much words differ.…

Digital learning increasingly makes use of realistic visualizations, although realism can be demanding for learners. Color coding is a popular way of helping learners understand visualizations and has been found to aid in learning with detailed visualizations. However, previous research has shown that color coding must not always be an effective…

The purpose of this article is to provide a theoretical account of the experience of stuttering that incorporates previous explanations and recent experimental findings. According to this account, stuttering-like disfluencies emerge during early childhood from excessive detection of cognitive conflict due to subtle limitations in speech and…

We investigated whether the phenomenological experience of mental time travel is similar when one travels as oneself versus with another possible self. Participants first described and rated their phenomenological experience for an autobiographical memory, a counterfactual event, and a future event (real-self condition). Then, they imagined…

It is difficult to monitor whether information was originally retrieved internally, from our own memory, or externally, from another person or a device. We report two experiments that examined whether people were more likely to confuse prior access to information on a smartphone with accessing their own knowledge. Participants were experimentally…

Both sketching and self-explanation are widely believed to be effective for problem-solving in science learning. However, it is unclear which aspects of these strategies promote learning and how they might interact. Compared to a read-only baseline, we examined the impact of instructing 11-year-old students to solve science problems to sketch,…

Studies on children's understanding of counting examine when and how children acquire the cardinal principle: the idea that the last word in a counted set reflects the cardinal value of the set. Using Wynn's (1990) Give-N Task, researchers classify children who can count to generate large sets as having acquired the cardinal principle…

Rubrics, which are designed to inform learners about assessment criteria and quality levels concerning a task assignment, are a widely used means to support learners in self-assessing their task performance. Usually, rubrics enhance task performance. Surprisingly, however, relatively little is known about the underlying mechanisms via which…

Classroom response systems (i.e., clickers) have become increasingly popular to facilitate student learning. Unfortunately, the common practice of pausing a lecture to ask questions takes up precious time to cover content. Asking questions "on the fly" without pausing is a possible solution. But can students both attend to lecture and…

We examined the relationship between the Early start Denver model (ESDM) intervention and mu rhythm attenuation, an EEG paradigm reflecting neural processes associated with action perception and social information processing. Children were assigned to either receive comprehensive ESDM intervention for two years, or were encouraged to pursue…

Statistical knowledge of a target's location may benefit visual search, and rapidly understanding the changes in regularity would increase the adaptability in visual search situations where fast and accurate performance is required. The current study tested the sources of statistical knowledge--explicitly-given instruction or experience-driven…

The use of realistic visualizations has gained considerable interest due to the proliferation of virtual reality equipment. This review is concerned with the theoretical basis, technical implementation, cognitive effects, and educational implications of using realistic visualizations. Realism can be useful for learners, but in several studies,…
