Abstract :
Purpose: Problem Based Learning is an approach to learning and instruction in which students tackle problems in small groups under the supervision of a tutor. This method is very useful in imparting medical education. In this study I am going to apply PBL in the teaching of undergraduate radiography students and study the effectiveness of PBL, particularly in teaching image processing methods in radiography.
Materials and Methods: A randomized controlled design was used for the study to test the addition of Problem Based Learning (PBL) to theory lectures and clinical experience versus theory and clinical experience alone on student’s knowledge in performing Image processing in radiography. The students were randomly selected and then randomly distributed either to experimental or control group. The knowledge is accessed by valid questionnaire through the pretest and post test for both the experimental and control group. The data are then analyzed by excel work sheet to get the result.
Results and Conclusion: Sixty radiography students from fourth semester were randomly assigned either to the experimental or control group, so that there were 30 students in each. The mean score for the pretest and posttest score are at 21.67 and 34.04 for experimental group with a standard deviation 4.44 and 3.44 respectively while it was 21.80 and 29.07 for the control group with a standard deviation of 3.88 and 3.85 respectively. This study shows that students' knowledge in performing image processing in radiography significantly enhanced after the application the PBL module.
