Learner characteristics associated with responses to film and interactive video lessons on smokeless tobacco

Video laboratories for the teaching and learning of professional ethics in exercise physiology curricula

Student researchers in physiology courses often interact with human subjects in classroom research but may be unfamiliar with the professional ethics of experimenter-subject interactions. This communication describes experiences related to an interactive video used in exercise science and general biology courses to help students become aware of, sensitive to, and comfortable with implementing professional ethics into their own thinking and behavior as researchers before entering the laboratory. The activity consisted of a filmed exercise physiology experiment complemented with interactive question sheets followed by small- and large-group discussion and culminating with individual student reflections. Student written responses from multiple courses indicated that students were able to 1) identify and consider the ethics of experimenter-subject interactions from the movie, 2) generalize broader ideas of professional ethics from those observations, and 3) consider their observations in terms of future experiments they would be conducting personally and how they should interact with human subjects. A majority of students indicated a positive reaction to the video and identified specific aspects they appreciated. It is hoped that this report will encourage other instructors to consider the use of interactive videos in the teaching and learning of professional ethics related to their courses.

Using an interactive computer game to increase skill and self-efficacy regarding safer sex negotiation: field test results

This article describes the development, field testing, and evaluation of an interactive computer program, "Life Challenge," developed by the New York State Department of Health as a tool for enhancing adolescents' sense of self-efficacy in HIV/AIDS prevention programs. The computer kiosks were field tested in 13 sites serving high-risk adolescents. The program uses a time travel adventure game format to provide information and nonthreatening skill practice. Users record and play back their responses as they "negotiate" with their chosen partners. A proof of concept evaluation with analysis of 211 audio responses found that users took negotiating tasks seriously; statistically significant learning gains were achieved on knowledge items and in self-efficacy scores (greatest improvement for those with low baseline self-efficacy levels). Challenges and problems encountered in implementing the project are described, and the potential of using computers for skill practice and educational interventions in health education is explored.

A comparison of smokeless tobacco and smoking practices of university varsity and intramural baseball players

To examine the smokeless tobacco (ST) and smoking practices of collegiate varsity and intramural baseball players, 284 undergraduate athletes at two major Southwestern universities were surveyed using a questionnaire previously developed to measure use among this population. About one-fourth of all athletes were current ST users and 4% smokers. Over half of varsity players (53%) compared to 25.9% of intramural players used one or both forms of ST. Varsity players were about 20 times more likely to use ST as to smoke, while intramural players were about five times as likely to use ST than to smoke. On both teams, use of chewing tobacco was associated with use of snuff. Smoking was not associated with ST use in either group. Mean ages for initiation for all products was 15, and for quitting, 18. There was no evidence that one form of tobacco served as a gateway for the other among these young adult athletes. Over a fourth of all users started after age 17, suggesting that college is an appropriate locus for both ST prevention and cessation programming. Such programs for this population must address the unique characteristics of the social environment in collegiate baseball.

Media manipulation of adolescents' personal level judgements regarding consequences of smokeless tobacco use

Videotapes were developed to try to impact on personal level judgements of concern and risk in the context of smokeless tobacco use, a growing substance use problem in adolescents. In a within-and-between-subjects design, convincingness (i.e., dramatic portrayal) of the videotaped message (high and low) and perceived probability of consequences portrayed in the message (high and low) were manipulated.
