The results of this study support our hypothesis that web-based education is effective in increasing the skills of students in the experimental group. In addition, some critical steps of the urinary catheterization procedure were performed better by the students of the web-based group. Despite the fact that web-based learning includes a virtual learning environment for students rather than real life context for practicing the skills, the use of video and pictures, which could be viewed by students repeatedly without any limitations of time and place, might have influenced their performance positively. Our result is consistent with the results of other studies. For example, Beeckman et al. (2008) conducted a study to detect problems when classifying pressure ulcers and to examine whether an e-learning program was able to increase the skills of qualified nurses and nursing students. They found that nursing students achieved better results when using the e-learning program. As stated in the introduction, Lu et al. (2009) assessed the effectiveness of supplementing conventional classroom teaching with web-based learning when teaching intramuscular injection nursing skills. They reported that participants achieved higher skill performance scores with web-based learning compared to conventional learning methods. In contrast, Bloomfield et al. (2010) investigated the effect of computerassisted learning versus conventional teaching methods on the acquisition and retention of hand washing theory and skills in pre-qualification nursing students. Their mode of instruction for the experimental group included computer-assisted instruction instead of web-based education, and they found no significant differences between the groups.
