This study involved the development and testing of a scale to assess the attitude of a student towards his student teaching experience. A four-state survey of teacher training institutions showed that no standardized instrument existed, although college coordinators were willing to use one. Items for the scale were generated by using a model including two institutions responsible for the student teaching experience, four psychological needs (for achievement, independence, self-esteem, and social approval) and 18 aspects of a student teaching experience. Development and testing involved 12 stages: 1) definition of concepts; 2) construction of 144 scale items; 3) classification of items according to need; 4) classification on favorableness-unfavorableness scale; 5) determination of reliability of (3) and (4); 6) selection of items for preliminary scale; 7) administration of scale to pilot group; 8) selection of items for final scale; 9) establishment of split-halves of final scale; 10) administration of final 50-item scale; 11) completion of scale by eight supervisors; 12) analysis of responses. The supervisors' and students' scores both showed that the majority of students were favorable to the student teaching experience. The internal validity of the scale seemed satisfactory, it was easy to administer and score, and took about 20 minutes to complete. It seems to be a reliable measure and may prove serviceable in helping to evaluate student teaching programs. (MBM)
