Correlating trainee attributes to performance in 3D CAD training

Purpose - The purpose of this exploratory study is to identify trainee attributes relevant for development of skills in 3D computer-aided design (CAD). Design/methodology/approach - Participants were trained to perform cognitive tasks of comparable complexity over time. Performance data were collected on the time needed to construct test models, and the number of features used to construct them. A written questionnaire survey profiled the trainees' technical capabilities, motivation, and dedication. Findings - Correlation analysis between the trainees' attributes/capabilities and performance showed that a mix of the trainees' psychological and technical attributes contributed to CAD competence development. Prior technical knowledge influenced initial performance whereas dedication had a strong influence on the rate of improvement. Practical implications - The methodology serves as basis for developing specific guidelines for constructing questionnaires for trainee profiling and for customizing the training of mechanical 3D CAD. Originality/value - This original research proposes a framework for classifying CAD-training candidates based on their technical and personality profiles, which may lead to more effective training
