We compared the effect of an innovative homework assignment with that of traditional homework assignments on students’ conceptual understanding of electromagnetic induction. Students in the experimental group were asked to interact with computer simulations, to present qualitative reasoning explaining the phenomena displayed on the simulations, and were supported with immediate feedback in the ...

The present study explored the effects of lecture fluency on students’ metacognitive awareness and regulation. Participants watched one of two short videos of an instructor explaining a scientific concept. In the fluent video, the instructor stood upright, maintained eye contact, and spoke fluidly without notes. In the disfluent video, the instructor slumped, looked away, and spoke haltingly wi...

In this lecture we will be looking into the secretary problem, and an interesting variation of the problem called the incentive comparable secretary problem. For both of these problems we will show how they can be solved though a correspondence between all possible strategies and the feasible solution space to a linear program. In both cases this will allow us to derive an algorithm and prove t...

Instructors continually search for innovative approaches to interact with and engage students in the classroom. The tablet offers a potential innovation for this purpose. Tablet devices from Apple, Microsoft, and other hardware vendors have overcome many of the challenges of the past (e.g. cost and limited applications) to become useful tools for instructors. Our paper examines instructor use o...

In general, minimally invasive surgery is seen as the most difficult surgery because there is limited field of view with an endoscope and force sensation from surgical instruments such as forceps is poor. Especially in early clinical education for medical students, a virtual reality surgical simulator would be an effective tool. In this paper, we propose a visuohaptic surgery training system fo...

In this paper we describe a method for developing a virtual instructor for pedestrian navigation based on real interactions between a human instructor and a human pedestrian. A virtual instructor is an agent capable of fulfilling the role of a human instructor, and its goal is to assist a pedestrian in the accomplishment of different tasks within the context of a real city. The instructor decid...
