Abstract: | The evaluation of the effectiveness of PLATO CAI in both educational and industrial settings is discussed. The evaluation of the PLATO instruction in the educational setting generally supports the effectiveness of PLATO instruction but was hampered by limited control of instructional method for different populations of students. Further difficulties in evaluation were caused by ceiling effects in the measurement instrument. Evaluation of PLATO instruction in the consulting setting was hampered by lack of cooperation by the client institution. Mastery of the content of some areas covered by the PLATO lessons in this setting was high, whereas mastery of other content areas was low. Conclusions address the necessity for at least a minimal amount of cooperation from the client institution and a minimal amount of control of the evaluation setting for adequate evaluation of any CAI instructional method. |
