title: Does computer-assisted instruction really help to improve the learning process?
abstract: OBJECTIVE
  We have developed both a computer-assisted instruction (CAI) multimedia program and a textbook on arterial blood gas interpretation with the same content as formal didactic instruction. A prospective, randomized study was designed to compare the outcomes of self-learning using the software and using the textbook.
  
  
  METHODS
  80 third-year medical students were randomly allocated to two groups: the CAI (n=40) and text group (n=40). A 30-item, type-K examination was administered as the pre-test. After the pre-test, the volunteers in the CAI group studied the software program, whereas those in the text group spent their time reading the textbook covering the same material. The post-test was held immediately at the end of a full day of study, and 3 weeks later, the final test was performed without prior notice. A P value of <0.05 was considered to be a statistically significant difference.
  
  
  RESULTS
  Students in the text group seemed to fulfil their assignments and improved their scores post-test better than those in the CAI group. After 3 weeks, the final test scores of both groups demonstrated a significant decrease, but showed an insignificant difference between the two groups.
  
  
  CONCLUSIONS
  Text-based learning seems to be a convenient method of education where time is limited. However, with more time available, use of software may be as good as the conventional learning method and can be an alternative tool. The computer-assisted instruction program seems to enhance the learning process.
