A comparison of two instructional approaches in teaching underground rock bolt installation with a Jackleg Drill

0
An integrated hypermedia training tool on underground rock bolting was evaluated using qualitative and quantitative methodologies to compare it with the traditional method of training underground rock bolters. Usability experiments performed underscore the need to evaluate a new product to ensure that it meets the requirements of users. Statistical results from comparative experiment indicate that a task must be sufficiently complex in order to render a traditional paper-based method less effective than a computer-based method. Additionally, participants in the computer-based group (n = 25) rated the training effectiveness more positively than those in the paper-based group (n = 25).
