Learning in practice for becoming a professional forensic expert

摘要

The study explores the professional development of future forensic experts. Specifically, it investigates how the forensic expert trainees learn through the internal training program at the Swedish National Laboratory of Forensic Science with a focus on the supervision at work. The findings are drawn from an ethnographical study where five trainees and their supervisors have been observed and interviewed. By drawing on a socio cultural perspective on learning, the results show that supervision is crucial for professional development. Two types of activities and relations define how supervision is implemented. There is a " transitional movement" in how supervision is staged depending on the trainees' gradual changes in participation in the work practice and increased experience. Forensic experts need skills and know-how to make wise and impartial judgments, i.e. a kind of tacit professional practical knowledge, as well as the skill to communicate with other professionals. However, the development of a professional language is somewhat unspoken or planned. Becoming a forensic expert is a learning process in practice where supervision plays a decisive role in maintaining the professional knowledge in the judicial system. Therefore, supervision for supervising might be a valuable support for supervisors.
