Abstract

A prototype computer-based training tool to improve WBC identification skills was developed. Students were assigned to complete five simulated WBC differentials but were allowed ample free time to use the tool at will to complete additional cases and to use the software in two alternative learning modes. The assignment was made at the end of the traditional WBC differential training activities in the first semester of hematology in the clinical laboratory science curriculum. The tool recorded usage data during the one month that students had access.

Student performance was compared to the consensus results from an expert panel of hematology instructors. Usage tracking data was extracted and reviewed. The performance data indicated that students varied in WBC identification skill on the assignment. The usage tracking data showed that students used the tool only slightly more than the assigned cases and did not use alternative learning modes.

Data from the expert panel indicated that the experts varied greatly in the number of discrepancies from the consensus opinion. Item analysis indicated the cell types that were most problematic.

The prototype experience prompted the creation of a revised subsequent version of the trainer that is now being evaluated in our CLS program. The new trainer is web-based offering personal computer and mobile device access.
