MAKING THE CASE ONLINE: HARVARD BUSINESS SCHOOL MULTIMEDIA

New media technologies provide opportunities to expand academic curriculum offerings and enhance student learning. Yet web-based and online learning tools should not be just repurposed text and information, or videotaped faculty lectures. Instead, the web calls for the inclusion of sound, text and visuals for learning tools that provide a media-rich environment. This allows faculty to create multidimensional experiences that cater to different learning styles and provide opportunities for problem solving. Drawing on my production experiences at HBS, as well as my own experience teaching visual anthropology and creating films, videos, photographs and web products, I discuss the teaching opportunities that new technologies and media can provide.     

A Systematic Uncertainty Analysis of an Evaluative Fate and Exposure Model

Multimedia fate and exposure models are widely used to regulate the release of toxic chemicals, to set cleanup standards for contaminated sites, and to evaluate emissions in life-cycle assessment. CalTOX, one of these models, is used to calculate the potential dose, an outcome that is combined with the toxicity of the chemical to determine the Human Toxicity Potential (HTP), used to aggregate and compare emissions. The comprehensive assessment of the uncertainty in the potential dose calculation in this article serves to provide the information necessary to evaluate the reliability of decisions based on the HTP A framework for uncertainty analysis in multimedia risk assessment is proposed and evaluated with four types of uncertainty. Parameter uncertainty is assessed through Monte Carlo analysis. The variability in landscape parameters is assessed through a comparison of potential dose calculations for different regions in the United States. Decision rule uncertainty is explored through a comparison of the HTP values under open and closed system boundaries. Model uncertainty is evaluated through two case studies, one using alternative formulations for calculating the plant concentration and the other testing the steady state assumption for wet deposition. This investigation shows that steady state conditions for the removal of chemicals from the atmosphere are not appropriate and result in an underestimate of the potential dose for 25% of the 336 chemicals evaluated.

Teaching with Multimedia: Do Bells and Whistles Help Students Learn?

ABSTRACT

This study compared 30 undergraduate social work and speech language pathology students' recall of material presented through multimedia versus traditional lecture. Advanced multimedia included audio, video, animation, graphics, text, and special effects. Traditional lecture included a text display in the form of PowerPoint bullets only. Both conditions presented material on the brain and the ear. Quantitative and qualitative results indicated that multimedia presentations had a positive effect on learning. Similar findings were obtained during a follow-up study three weeks later.
