BACKGROUND This randomized, single-blinded, controlled study compares the effectiveness of two modes of delivering the same set of oral hygiene instructions: those loaded on a computer-assisted teaching format versus those given personally by a self-care instructor. METHODS 60 participants with mild to moderate periodontitis were randomized to either the computer-teaching format or the self-c...

INTRODUCTION More than a million people in the USA and Europe suffer a sudden cardiac arrest each year. Thousands of people have to be trained in delivering help in such a situation. This cluster-randomized study compared two refresher training methods for basic life support and use of an automated external defibrillation: a traditional instructor-led course, and self-instruction by poster. M...

Use of in-class concept questions with clickers can transform an instructor-centered "transmissionist" environment to a more learner-centered constructivist classroom. To compare the effectiveness of three different approaches using clickers, pairs of similar questions were used to monitor student understanding in majors' and nonmajors' genetics courses. After answering the first question indiv...

The Kinect sensor gives computer eyes. It can capture 3D coordinates of human body joints. This provides a convenient way to track human body movement. This paper proposes an on-line physical training system using 3D sensors (Kinect) so that the exercise instructor and the athletes who are not in the same location can collaborate and fulfil training tasks remotely. The system captures the motio...

You are about to teach a course that will probably give students their second exposure to linear algebra. During their first brush with the subject, your students probably worked with Euclidean spaces and matrices. In contrast, this course will emphasize abstract vector spaces and linear maps. The audacious title of this book deserves an explanation. Almost all linear algebra books use determin...

We describe the design of Instructor Rating Markets in which students trade on the ratings that will be received by instructors, with new ratings revealed every two weeks. The markets provide useful dynamic feedback to instructors on the progress of their class, while at the same time enabling the controlled study of prediction markets where traders can affect the outcomes they are trading on. ...

BACKGROUND Self-directed BLS-training, using a personal training manikin with video has been shown to be as effective as instructor-led training. This has not previously been investigated for AED-training. MATERIALS AND METHODS This prospective, randomized study with a non-inferiority design compared traditional instructor-led training with three DVD-based AED-training methods (2.5min DVD wit...
