Optimizing educational video through comparative trials in clinical environments

Although video is increasingly used in public health education, studies generally do not implement randomized trials of multiple video segments in clinical environments. Therefore, the specific configurations of educational videos that will have the greatest impact on outcome measures ranging from increased knowledge of important public health issues, to acceptance of a voluntary HIV test, remain largely unknown. Interventions can be developed to run on affordable handheld computers, including inexpensive tablets or netbooks that each patient can use individually, and to integrate video delivery with automated data collection. These video interventions can then be used not only to educate patients who otherwise might not be reached, but to examine how content can be optimized for greater effectiveness as measured by cognitive and behavioral outcomes. This approach may prove especially valuable in high volume urban facilities, such as hospital emergency departments, that provide points of contact for lower income, lower literacy, and high-risk populations who may not otherwise interact with healthcare providers or researchers. This article describes the development and evaluation of an intervention that educates emergency department patients about HIV prevention and testing while comparatively examining a set of videos, each based upon competing educational theories. The computer-based video intervention and methodology are both highly replicable and can be applied to subject areas and settings far beyond HIV or the emergency department.     

Modernization of an anatomy class: From conceptualization to implementation. A case for integrated multimodal–multidisciplinary teaching

It has become increasingly apparent that no single method for teaching anatomy is able to provide supremacy over another. In an effort to consolidate and enhance learning, a modernized anatomy curriculum was devised by attempting to take advantage of and maximize the benefits from different teaching methods. Both the more traditional approaches to anatomy teaching, as well as modern, innovative educational programs were embraced in a multimodal system implemented over a decade. In this effort, traditional teaching with lectures and dissection was supplemented with models, imaging, computer‐assisted learning, problem‐based learning through clinical cases, surface anatomy, clinical correlation lectures, peer teaching and team‐based learning. Here, we review current thinking in medical education and present our transition from a passive, didactic, highly detailed anatomy course of the past, to a more interactive, as well as functionally and clinically relevant anatomy curriculum over the course of a decade.

Computerized adaptive testing in instructional settings

Item response theory (IRT) has most often been used in research on computerized adaptive testing (CAT). Depending on the model used, IRT requires between 200 and 1,000 examinees for estimating item parameters. Thus, it is not practical for instructional designers to develop their own CAT based on the IRT model. Frick improved Wald's sequential probability ratio test (SPRT) by combining it with normative expert systems reasoning, referred to as an EXSPRT-based CAT. While previous studies were based on re-enactments from historical test data, the present study is the first to examine how well these adaptive methods function in a real-time testing situation. Results indicate that the EXSPRT-I significantly reduced test lengths and was highly accurate in predicting mastery. EXSPRT is apparently a viable and practical alternative to IRT for assessing mastery of instructional objectives.     

Marital support giving as a function of attributional confidence

This study sought to investigate the relationship between attributional confidence and social and emotional support. Consistent with uncertainty reduction theory, it was hypothesized that as relationships develop, so too should relational partner ability to predict spousal behaviors, thoughts, and feelings as well as provide appropriate social and emotional support. Two hundred sixty‐nine married people completed several measures assessing perceived attributional confidence, emotional support and social support of their partner. Results indicated a positive relationship between attributional confidence and interpersonal depth, social and emotional support as well as a negative relationship between attributional confidence and interpersonal conflict. Results are discussed in terms of Uncertainty Reduction Theory.     

Argumentativeness and verbal aggressiveness as a function of locus of control

This study examined argumentativeness, verbal aggressiveness, and general control expectancies. Two hundred ten (N=210) participants completed the Argumentativeness Scale, the Verbal Aggressiveness Scale, and a modified version of the Three‐Factor Locus of Control Scale. Results indicate that individuals who reportan internal control orientation were found toreport lower levels of argument avoidance than externals. Externals reported higher levels of verbal aggressiveness than internals. Further, an external locus of control orientation was positively related to verbal aggressiveness. Internal locus of control orientation was negatively related to tendency to avoid arguments. The findings provide further evidence into the relationship between control expectancies and aggressive communication traits.     

Retest reliabilities of ten scales of public speaking performance

On two different occasions twelve judges rated each of 30 short filmed speeches on each of 10 scales of speaking performance. The retest reliability of each judge on each scale was calculated. Median retest reliability of the twelve judges was highly correlated with years of training and experience in the teaching of speech. There was a tendency for global characteristics to be rated more reliably than specific observable characteristics.
