When considering the use of computers in their lessons, two questions are important for teachers: how to select courseware and how the role and practice of the teacher may change by using computers. To answer the first question, a courseware-selection checklist was developed and its use by teachers was investigated. The checklist serves the function of helping teachers select courseware in order to meet a specified goal with a specified audience. Concerning the second question, observations were conducted to determine how a group of teachers were using computers and interviews were held with these teachers to become aware of their experiences, their feelings, and their problems. The results of these investigations are being used to develop a school-based workshop to inform non-computer-using teachers of the possibilities, advantages, and the non-threat of using computers, and to support these teachers with examples and suggestions.
