Pre-trip inspection, Computer-based Training, Commercial Driving License Training, Computer-based assessment


Pre-Trip Inspection of the truck and trailer is one of the components of the current Commercial Driver's License (CDL) test. This part of the CDL test checks the ability of the student to identify the important parts of the commercial vehicle and their potential defects. The Virtual Check Ride System (VCRS), a computer-based application, is an assessment and feedback tool that mirrors the inspection component of the actual CDL. The VCRS has provided an after action review (AAR) via a feedback session that helps in identifying and correcting drivers' skill in inspecting parts and for overall safety. The purpose of this research is to determine the effectiveness of the VCRS in truck driving training programs. An experimental study was conducted with truck driving students at Mid Florida Tech, located in Orlando, Florida. The students were divided into control and experimental groups. Students in the both groups received regular training provided by Mid Florida Tech. The experimental group received additional training by making use of the VCRS. A total of three paper-based tests were given to all subjects during first three weeks; one test at the end of a week. Both groups were given the same paper-based tests. A two-way analysis of variance was conducted to evaluate the effect of the VCRS in the experimental group. This analysis found a significant difference between control and experimental groups. This effect showed that the students in the experimental group increased their performance by using VCRS. Moreover, there was a main effect in the scores of each week. However, there was not an interaction between the two factors. Follow up Post Hoc tests were conducted to evaluate the pair-wise differences among the means of the test week factors using a Tukey HSD test. These Post Hoc comparisons indicated that the mean score for the third week's test scores were significantly better than the first week's test score in the experimental group. It was concluded that the VCRS facilitated learning for the experimental group and that learning also occurred for both groups as a result of repeated testing.
