An investigation of the relationship between teaching experience, teacher concern level, and achievement of learning a new teaching skill for teachers in elementary school science is described in this report. For the purpose of studying these relationships, a computer-assisted instructional program was developed to teach the identification and use of behavioral objectives in science. The sample (34 experienced elementary school teachers and 26 undergraduate elementary education majors) was given a pretest and posttest on both the Teacher Concerns Statement and Behavioral Objective Achievement Test. After the pretest, each subject worked at the computer terminal with the computer program, and then, as a group, was administered the posttest. Major findings were: individuals without teaching experience tend to have a higher level of achievement than those with teaching experience; there was no significant relationship between the level of teacher concerns and achievement in identifying and using behavioral objectives for either experienced or inexperienced teachers; there was a significant positive correlation between teaching experience and teacher concern level; and teaching experience and teacher concern levels were not useful in predicting teacher achievement.
