What can you do to virtually teach the hands-on skills traditionally taught in labs? If you include simulations, active experimentation, discovery-learning techniques, numerous questions with detailed feedback, video, animations, and photographs, you can effectively teach practical hands-on skills through multimedia technology. Through discussion and demonstration, this session will highlight p...

The cognitive-theoretic instructional and assessment approaches described here represent our efforts to develop and measure students' abilities to reason spontaneously and flexibly with statistics in the context of complex real-world activity. We report results from two instructional projects based on situated cognition, in which students were taught statistical reasoning through guided partici...

Many educational organizations are motivated to create and share instructional videos, but there are no guidelines about the presentation styles. In practice, the presentation style of video lectures ranges from simple video capturing of classroom teaching, up to highly elaborate authoring of video presentations that include closeups and video-cuts of instructors, slides, animations, and intera...

In this review we argue that interactivity can be effective in video-based models to engage learners in relevant cognitive processes. We do not treat modeling as an isolated instructional method but adopted the social cognitive model of sequential skill acquisition in which learners start with observation and finish with independent, self-regulated performance. Moreover, we concur with the noti...

BACKGROUND Increased belt-positioning booster seat (BPB) awareness and access have led to increased use in the USA. Although transportation in Beijing is rapidly becoming 'motorised', Beijing's population has limited awareness of or access to BPBs. OBJECTIVE To explore the efficacy and acceptability of using a US-developed BPB use promotion intervention in Beijing. DESIGN Methods were adapt...

We assessed attitudes and preferences toward HIV self-testing (HIVST) among Zambian adolescents and adults. We conducted a population-based survey of individuals aged 16-49 years old in Lusaka Province, Zambia. HIVST was shown to participants through a short video on oral fluid-based self-testing. In addition to demographics, HIV risk perceptions, and HIV testing history, we assessed participan...

Computer driven biometric analysis of athlete’s movements have proven themselves as effective sports training tools. Most current systems rely on the use of retro-reflective markers or magnetic sensors to capture the motion of the athlete, so the biometric analysis can be performed. Video based training tools have also proved to be valuable instructional aids, however most require significant h...

Computer and video games are a prevalent form of entertainment in which the purpose of the design is to engage players. Game designers incorporate a number of strategies and tactics for engaging players in “gameplay.” These strategies and tactics may provide instructional designers with new methods for engaging learners. This investigation presents a review of game design strategies and the imp...

In this paper, we present a novel methodology for using Hidden Markov Models (HMM) to recognize marker-less human actions in videos. We use Scale Invariant Feature Transform (SIFT) keypoints to identify and track the trajectories of objects and major body parts in instructional videos. Then, we use a HMM to recognize the trajectories as a human action. This enables the use of readily available ...

Because of the visual complexity of medical images and the intensive tutorial experience required to develop image recognition expertise, professional training programs have concentrated on educating limited numbers of experts. Videodisk and CD-ROM (compact disk read only memory) image storage media now make it possible for a microcomputer workstation to provide a learning environment substanti...
