A study of the effectiveness of the scholastic aptitude test of the College Entrance Examination Board as a predictor of provisional certification of biology teachers at Ball State University during the period between September of 1965 and June of 1974

The purpose of this research was to examine the records of all students who pursued a curriculum at Ball State University which could lead to provisional certification to teach biology in the public schools of Indiana, covering retrospectively, all consecutive years for which complete records could be retrieved, to determine if such provisional certification to teach biology could be predicted by the examination of test scores made by students on the Scholastic Aptitude Test of the College Entrance Examination Board.A statistical comparison was made between the Scholastic Aptitude Test scores of those persons achieving provisional certification to teach biology in the public schools of Indiana and those persons not achieving such provisional certification, to determine whether Scholastic Aptitude Test scores in and of themselves could be used to predict provisional certification to teach biology in the public schools of Indiana.The records of all students at Ball State University who at any time between September of 1965 and June of 1974 pursued a course of study which, if completed, would lead to provisional certification to teach biology in the public schools of Indiana were examined, excluding all who had not been graduated by June of 1974 and those who did not have Scholastic Aptitude Test scores in their files at Ball State University.These students were divided into two groups, Group one was made up of those students who achieved provisional certification to teach biology in the public schools of Indiana and consisted of 331 students, Group two was made up of those students who failed to achieve provisional certification to teach biology in the public schools of Indiana and consisted of 244 students,A statistical comparison was made of the two groups - those certified (group one) versus those who were not certified (group two) - by the use of discriminant analysis, using as variables within the two groups, the bivarients (1) verbal score made on the Scholastic Aptitude Test, and (2) mathematical score made on the Scholastic Aptitude Test, The method of discriminant analysis combines variables within the two groups and then compares those groups on the basis of group differences without regard for their interrelations and partly overlapping information.The statistical analysis of the two groups indicated that there was no significant difference in the scores attained by the students in the two groups on the Scholastic Aptitude Test of the College Entrance Examination Board. The conclusion was made that scores made on the Scholastic Aptitude Test of the College Entrance Examination Board are not valid predictors of provisional certification of biology teachers at Ball State University during the period between September of 1965 and June of 1974.The study recommends that the Scholastic Aptitude Test of the College Entrance Examination Board be evaluated in all areas of advisement, including high school, junior college, and university advisement.The study further recommends that scores attained on the Scholastic Aptitude Test of the College Entrance Examination Board not be used in situations to which they are not applicable and for which they were not designed.The study further recommends that the Scholastic Aptitude Test of the College Entrance Examination Board be totally reexamined by qualified independent researchers to determine not only the value of this test as currently applied, but other possible ways in which this test can be used with validity.Thesis (D.
