      computer-based testing.

AB  - PURPOSE: This study investigated the relationship between the item response time 
      (iRT) and classic item analysis indicators obtained from computer-based test 
      (CBT) results and deduce students' problem-solving behavior using the 
      relationship. METHODS: We retrospectively analyzed the results of the 
      Comprehensive Basic Medical Sciences Examination conducted for 5 years by a CBT 
      system in Dankook University College of Medicine. iRT is defined as the time 
      spent to answer the question. The discrimination index and the difficulty level 
      were used to analyze the items using classical test theory (CTT). The 
      relationship of iRT and the CTT were investigated using a correlation analysis. 
      An analysis of variance was performed to identify the difference between iRT and 
      difficulty level. A regression analysis was conducted to examine the effect of 
      the difficulty index and discrimination index on iRT. RESULTS: iRT increases with 
      increasing difficulty index, and iRT tends to decrease with increasing 
      discrimination index. The students' effort is increased when they solve difficult 
      items but reduced when they are confronted with items with a high discrimination. 
      The students' test effort represented by iRT was properly maintained when the 
      items have a 'desirable' difficulty and a 'good' discrimination. CONCLUSION: The 
      results of our study show that an adequate degree of item difficulty and 
      discrimination is required to increase students' motivation. It might be inferred 
      that with the combination of CTT and iRT, we can gain insights about the quality 
      of the examination and test behaviors of the students, which can provide us with 
      more powerful tools to improve them.
