The effectiveness of detective training in forensic DNA evidence: A hierarchical formative evaluation.

摘要

The research study examines the efficacy of a collaborative forensic biology/DNA training program. The study establishes a unique model of evaluation derived from the educational field. The study is timely in developing forensic science training programs to criminal justice agencies and mirrors the national agenda for the development and monitoring of training programs.; The specific focus is to determine the efficacy of training, evaluating knowledge and understanding of forensic biology/DNA concepts and procedures. The study evaluates the retention of information, the ability to utilize the information, and identifies future training needs.; The study develops a model to measure the efficacy of the collaborative training program. An educational model, a hierarchical formative evaluation is developed. The model is further developed and operationalized by incorporating a widely accepted educational taxonomy on cognitive thinking skill levels, resulting in an evaluation model that is a unique approach to measure the efficacy of training at several different levels.; A self-administered survey instrument is the primary data source. The survey data is complemented by secondary data. The research utilizes a non-equivalent control group, ex post-test design. The sample is a convenience sample.; The study's findings are applicable at several different levels. First, the study determined the training was effective, well received, identifies additional specific topic related training, and recommends other program enhancements.; Second, from a national perspective, the research is applicable for future development of training in forensic sciences for police detectives and criminal justice agencies. Currently, there is the start of a national effort, the "Justice for All Act of 2004" to develop formal forensic science training programs for all elements of the criminal justice community. Also, the research validates the collaborative training model. The collaborative approach demonstrates a successful method to accomplish forensic science education for the criminal justice community in the future. This research on the development of the hierarchical formative evaluation model and confirmation of the collaborative training model will both significantly contribute to the national agenda.; Lastly, the National Institute of Justice (NIJ) is developing a model to measure the effectiveness of training. This model presented accomplishes the future requirement.
