Case based Study: Computer Visualization of Engineering Problems and its Impact on Student Learning
Keywords:Visualization techniques, Student Learning, Web-based Learning, Formative Assessments, Summative Assessments
To investigate the effects of computer-based visualization techniques on engineering students' diagnostic competence in the context of a web-based learning environment containing case-based work examples, two main studies were conducted. In the first experimental study, the learning results were measured by a formative assessment such as in-class activities, quizzes, case studies, etc. Data was collected and measured using a questionnaire that was randomly distributed to the electrical engineering students. It was found that the acquisition of knowledge can be supported by eliciting the use of 2D, 3D images, drawings or illustrations, etc. It was also noted that learners with low levels of prior topic knowledge profited from the computer-based visualization techniques. In the second study, results were analyzed from the summative assessments such as final exams, final practical tasks, and final projects where positive impacts were observed on students’ learning. Overall, the findings underline the “direct” relevance of the quality of knowledge attainment by learning from computer-based visualization techniques.
