Inservice for Vocational Instructors in Serving Special Needs Students. A Course Follow-Up Study. Project Report.
Wentling, Tim; And Others
Utilizing three different techniques, a follow-up survey of participants in a vocational education course was conducted to determine which technique collects the most useful information efficiently. The course participants were divided into thirds and, using the same questionnaire, data was collected from each third via one of the following three techniques: (1) a mail-out questionnaire, (2) personal interviews, and (3) telephone interviews. It was found that the personal interviews by phone and visitation, although introducing a bias, gave the best and most useful information. Control over the question responses was lost by mailing the questionnaire. People tended to leave all the open-ended questions blank and sometimes responded incompletely or incorrectly to the other multiple choice questions. This suggests that the personal interview is the best technique if subjective information and open-ended responses are being sought, but that the mail-out technique is more useful when collecting objective types of data. Also, it was found that the visitation personal interview, although costly, did not give much more information than the telephone interviews. (This report outlines the general procedure, strengths, and weaknesses for each of the three techniques. The questionnaire, a sample script for a telephone interview, and a follow-up letter to non-respondents are appended.) (EM)
