Portfolio Instrument for Assessing Pre-service Technology Teachers

The Teacher Education Law states that a certified teacher has to complete one-year teaching internship after graduating from the university. Evaluating pre-service teachers of living technology at junior high schools and selecting the evaluation norms are urgent issues for educators. Therefore, it is very necessary to develop a Portfolio Instrument, along with a user’s manual, and establish its validity and reliability, as discussed in this study. The methodology for this study included a literature review, a nominal group discussion, a panel discussion, formal evaluation, and questionnaires. The nominal group began this study by developing the content of the instrument. The draft of the instrument was made, tested, and then revised by the researchers. Finally, the draft was thoroughly revised by a panel of six experts to establish the validity of the instrument. A committee of five senior teachers and a professor of living technology was formed to evaluate five technology teachers. The reliability (Cronbach£\Coefficient of Internal Unanimity and the Kendall Coefficient of Concordance) of the instrument was high. The questionnaires were then field-tested to investigate the responses to the usage of the instruments. Finally, conclusions and suggestions are provided based on the obtained results.
