The purpose of the mixed quantitative/qualitative study discussed here was to ascertain the beliefs Purdue Extension Resources have regarding Computer-Based Instruction (CBI) for in-service training. Seventeen educators participated in the in-service training using two of five technical sections from an aquaculture CD-ROM tutorial. Educators completed pre-training questionnaires, content assessments, post-instruction evaluations, and follow up interviews. Educators participating in this study had favorable views toward the use of CBI for in-service training programs. The ability to spend less time out of their county and to review materials after the training were two of the key CBI benefits cited by educators
