A model of cognitive control in task switching is developed in which controlled performance depends on the system maintaining access to a code in episodic memory representing the most recently cued task. The main constraint on access to the current task code is proactive interference from old task codes. This interference and the mechanisms that…

In multilevel modeling (MLM), group-level (L2) characteristics are often measured by aggregating individual-level (L1) characteristics within each group so as to assess contextual effects (e.g., group-average effects of socioeconomic status, achievement, climate). Most previous applications have used a multilevel manifest covariate (MMC) approach,…

People often make inferences with incomplete information. Previous research has led to a mixed picture of how people treat missing information. To explain these results, the authors follow the Brunswikian perspective on human inference and hypothesize that the mechanism's accuracy for treating missing information depends on how it is distributed…

Factor mixture models are latent variable models with categorical and continuous latent variables that can be used as a model-based approach to clustering. A previous article covered the results of a simulation study showing that in the absence of model violations, it is usually possible to choose the correct model when fitting a series of models…

This study investigated how students' knowledge of a particular domain influences the type of investigative strategy they utilize in an inquiry learning task within that domain. Students with high domain knowledge were assumed to employ a theory-driven strategy, whereas less knowledgeable students were expected to start off in a data-driven mode…

Take-the-best (TTB) is a fast and frugal heuristic for paired comparison that has been proposed as a model of bounded rationality. This heuristic has been criticized for not taking compound cues into account to predict a criterion, although such an approach is sometimes required to make accurate predictions. By means of computer simulations, it is…

This case study investigated the perceptions of Maori students in the Virtual Learning Network of what constituted effective strategies for engaging them in online learning. In the FarNet cluster, about 63 students from the four secondary and five area schools access the VLN, and approximately 80 percent of those students are of Maori descent.…

Problem Statement: Computerized adaptive testing (CAT) is a sophisticated and efficient way of delivering examinations. In CAT, items for each examinee are selected from an item bank based on the examinee's responses to the items. In this way, the difficulty level of the test is adjusted based on the examinee's ability level. Instead of…

This paper is intended for engineering educators, high school curriculum designers, and high school teachers interested in integrating authentic, project-based learning experiences into their classes. These types of projects may appear complex, but have many advantages. We characterize the successful implementation of one such project, the…

This paper describes the author's experience with a pilot course of Italian in SL®[superscript 2]. The course is part of a PhD research on "Exploring the potential of virtual worlds to promote Intercultural Awareness in students learning Italian as a Foreign Language." In the paper the author will justify her choice of virtual worlds for…

Students in all areas of computing require knowledge of the computing device including software implementation at the machine level. Several courses in computer science curricula address these low-level details such as computer architecture and assembly languages. For such courses, there are advantages to studying real architectures instead of…

Expectations for simulations in healthcare education are high; however, little is known about healthcare students' expectations of the learning process in virtual reality (VR) and simulation-based learning environments (SBLEs). This research aims to describe first-year healthcare students' (N=97) expectations regarding teaching, studying, and…

The serious games community is moving toward research focusing on direct comparisons between learning outcomes of serious games and those of more traditional training methods. Such comparisons are difficult, however, due to the lack of a consistent taxonomy of game attributes for serious games. Without a clear understanding of what truly…

The authors investigate the potential of semantic web technologies to enhance "Virtual Fieldwork" resources and learning activities in the Geosciences. They consider the difficulties inherent in the concept of Virtual Fieldwork and how these might be reconciled with the desire to provide students with "authentic" tools for…

This study explored computer animation vignettes as a replacement for live-action video scenarios of classroom behavior situations previously used as an instructional resource in teacher education courses in classroom management strategies. The focus of the research was to determine if the embedded behavioral information perceived in a live-action…
