Effects of 18/1 and 30/1 Student-Instructor Ratios on Student Achievement and Instructor Activities in a Computer Managed Course.
Squire, Lisa; And Others
This study investigated the effects of an 18/1 versus a 30/1 student-instructor (S-I) ratio on instructor behavior and student achievement in a computer-managed Navy technical school. Students were randomly assigned to two learning centers in which in 18/1 S-I ratio was maintained, while a 30/1 S-I ratio was maintained in two other learning centers. These learning centers were operated identically for four months, except for the difference in the S-I ratio. Student achievement measures obtained from the computer system included course completion times, knowledge test scores, performance test data, and student attrition rates. The data indicate that increasing the S-I ratio from 18/1 to 30/1 proportionally increased the frequency of required administrative interactions between student and instructor. Under the higher S-I ratio less instructor time was available to the student for direct instructional contact. There was no significant difference in student achievement measures or attrition rates as a result of the different S-I ratios, but there was some evidence of a performance decrement. The results indicate that a 30/1 S-I ratio can be used effectively in a learning center environment. (Authors)
