THE INTENT OF THIS INVESTIGATION WAS TO COLLECT AND MAKE KNOWN SELF-EVALUATION TECHNIQUES FOR PHYSICAL SCIENCE TEACHERS AND TO DISCUSS THE USE OF SUCH TECHNIQUES. A TOTAL OF 191 PHYSICAL SCIENCE INSTRUCTORS COMPLETED A QUESTIONNAIRE REQUESTING INFORMATION ON THE USE OF 17 SELF-EVALUATION TECHNIQUES, REPORTING THAT A TECHNIQUE WAS FOUND TO BE "VALUABLE,""DOUBTFUL" OR "NO VALUE," AND "MIGHT BE INTERESTED IN TRYING IT." THE USE OF SELF-EVALUATION PROCEDURES BY PHYSICAL SCIENCE INSTRUCTORS WAS ALSO COMPARED TO THE USE OF SUCH TECHNIQUES BY INSTRUCTORS IN OTHER FIELDS. THE AUTHOR CONCLUDED THAT (1) THE USE OF SELF EVALUATION TOOLS AMONG PHYSICAL SCIENCE TEACHERS IS WIDESPREAD, (2) THE MOST USED TOOLS ARE NOT THE ONES WITH THE HIGHEST SUCCESS RATIOS, AND (3) MOST COLLEGE INSTRUCTORS ARE UNFAMILIAR WITH MANY AVAILABLE SELF-EVALUATION TOOLS.
