Science textbooks often include text and diagrams to aid learner understanding. Yet traditional written instructions in textbooks often separate them, which can increase cognitive load and hinder effective learning. This research proposes and tests a novel presentational format for written instruction that incorporates spatial contiguity, numbered…

What happens when an individual spinal nerve is damaged or severed? The loss of function upon nerve damage is a straightforward concept to understand. But what if that spinal nerve contributes to the brachial plexus? The brachial plexus can be an intimidating structure for students, but this structure is also rich in regional anatomy connotations…

An experimental study was conducted to examine the effects of shared book reading and video viewing on preschoolers' vocabulary and knowledge acquisition in informational text. The study included 60 preschool children who were randomly assigned to three experimental groups --shared book reading group, video viewing group, and shared book reading…

In educational contexts, questioning performs a number of functions. These include facilitating learning in the classroom and the recognition of achievement through examinations and other assessments. Good quality questions are important to ensuring that these functions are achieved. This research focused on educational exams and used views from…

Conceptual modeling of databases is a complex cognitive activity, particularly for novice database designers. The current research empirically tests a new pedagogy for this activity. It examines an instructional approach that stresses visualizing gradual transitions between levels of abstraction in different hierarchic levels of a relational…

Earlier research has found that it is useful to distinguish situations in which students construct external representations on their own from situations in which they are expected to interpret already provided external representations. One type of representations that is particularly important for teaching mechanics is the free-body diagram. In…

Instructional images are used widely in textbooks and other learning materials, but the role of learner interpretation has not been adequately explored. While previous research has demonstrated the diversity of interpretation derived from images by learners, this research has not consistently taken place in the context of authentic learning tasks.…

We apply a "tutorial design process", which has proven to be successful for a number of physics topics, to design curricular materials or "tutorials" aimed at improving student understanding of important concepts in a university-level introductory materials science and engineering course. The process involves the identification…
