One significant challenge in the field of measuring ability is measuring the current ability of a learner while they are learning. Many forms of inference become computationally complex in the presence of time-dependent learner ability, and are not feasible to implement in an online context. In this paper, we demonstrate an approach which can…

In this study the impact of a mobile augmented reality learning environment on motivation, learning effects and cognitive load was tested. Students participated in a two-hour history lesson while using their smartphones to turn static pictures into animations with an Augmented Reality (AR) application. Interest, perceived competence and perceived…

Online adaptive tutoring systems are increasingly being used in classrooms as a way to provide guided learning for students. Such tutors have the potential to provide tailored feedback based on specific student needs and misunderstandings. Bayesian knowledge tracing (BKT) is used to model student knowledge when knowledge is assumed to be changing…

Social facilitation as a self-presentational display, and social performance impairment attributable to perceived public failure, are examined in a study of context effects in verbal learning. Female undergraduates (N=72) served as subjects with one male who served as an "audience." Performance data indicate that, consistent with the present…

The relationship between instruction and instructional design is explored. The aim of instruction is to assist the individual as learner. The Learner, the Content, the Media, the Teacher Function, and the Context within which learning is to occur interact during a period of time to form an instructional episode (the CMT paradigm). Considering all…

A project to determine the level of development complexity necessary to produce cost-effective instruction is described. The project is designed to investigate alternative levels of instructional development complexity, how these different levels affect spending, varying degrees of student achievement associated with each level, and the time…

The Domain of Cognition is a taxonomy for planning, sequencing, and implementing instruction, which covers the entire range of cognitive and cognitive-affective learning and behavior. Students acquire, learn, and use information on eight hierarchically and sequentially arranged levels of complexity. The levels and their corresponding abilities…

Current research and learning theory suggest that a hierarchy of proportional reasoning exists that can be tested. Using G. Vergnaud's four complexity variables (structure, content, numerical characteristics, and presentation) and T. E. Kieren's model of rational number knowledge building, an epistemic model of proportional reasoning was…
