Ubiquitous tutoring in laboratories based on wireless sensor networks

Industrial education places a high premium on experiences in practical hands-on training, though it is commonly recognized for the deprivation in its opportunities of student performance analysis due to lack of recorded data as such. In the present study, the technology of wireless sensor networks has been implemented in the tutoring in courses offered in laboratory skills, where the students' experimental skills and learning inclinations have been examined. Two sets of questionnaires in the respective aspects have been developed to be administered in order to have pretest-posttest scores obtained. As illustrated in the results derived from the study, a learning environment where wireless sensor networks provide a significant degree of support during laboratory sessions, student performance had significantly improved, and this has been proven evidently for the students in the low-achievement group when being compared to the results delivered by the students in the high-achievement group.
