A Study on the Efficiency of Using the Aircraft Mechanic Training Aid Handbook: A Case Study of the 23rd Aircraft Maintenance Technical Inspector and Supervisor Course

Abstract

   The objectives of this study are to: 1. study the efficiency on using an Aircraft Mechanic Training Aid Handbook with an 85/85 criteria and 2. compare the learning outcomes before and after the training. The samples were fifteen students studying in the 23^rd Aircraft Maintenance Technical Inspector and Supervisor Course. The research tools included the Aircraft Mechanic Training Aid Handbook, the training aids, hands-on skill record forms, and the learning achievement tests. To determine the learning achievement from the use of handbook, the pre-and post-training outcomes were evaluated using mean, standard deviation, and t-test dependent.

   The research results showed that: 1. the samples’ achievement test scores after the training using the handbook were 88.53/92.00 which reflected the efficiency related to the criteria, and 2. the results after using the Aircraft Mechanic Training Aid Handbook in the 23^rd Aircraft Maintenance Technical Inspector and Supervisor Course, showed that the samples’ practical-test scores after the training were increased with a statistical significance at 0.05. This indicates the effectiveness of the handbook used in the training that it has positive effects on the samples’ post-test scores.
