Development and evaluation of a computer based test for anatomy radiographic course examination

Abstract

The assessment of the anatomical radiography course is to measure the student’s ability to identify anatomy on radiographic images. Conventional paper tests have used radiographic images. The limitations of this method are the number of radiographic films and the time-consuming assessment process. This study aimed to develop a computer-based test (CBT) to multiply the instruments, store pictures, and speed up the assessment time. The CBT software can reproduce radiographic images using digital files and a feature to add overlay markers. The placement of markers is done intuitively via a user interface with drag and drop motion recognition. The CBT software also provides features for instrument bank, instrument selection and management for exams, a relational database for examinee identities and exam entries, and automatic grading. CBT development uses the Waterfall Software Life Cycle (SDLC), with black-box testing using the normal value equivalent partition method. The CBT usability test was carried out by measuring user perceptions (5 administrators and 60 students) and comparing them with conventional methods at the 95% significance level. Research time decreased significantly during instrument preparation and the assessment process. User perceptions show that 76% of students and 85% of managers give positive assessments. There is no difference between conventional and CBT assessments with a p-value = 0.067 (p-value > 0.05) so that CBT is very potential to be used as a substitute for conventional paper-based tests in examining anatomical radiography courses.
