6. Distance-Learning Challenges Distance Learning has become very popular as an economic option of delivering undergraduate engineering education to the learners at various distant geographic locations Hands-on laboratory practice is essential part of engineering technology (ENT) programs Delivery of laboratory exercises to the distant learners is a problem demanding solution 6 Mert Bal, Assessment of Remote Laboratory Practices in Engineering Technology Distance-Education ASEE 2014 – International Forum – Indianapolis, IN - June 14, 2014

7. Lab Delivery Solutions the lab kits that contain small, inexpensive laboratory equipment that each student either purchases one or given one by the university in order to do the labs at a distance location 7 useful for delivering the labs of the courses that do not require sophisticated lab equipment Mert Bal, Assessment of Remote Laboratory Practices in Engineering Technology Distance-Education ASEE 2014 – International Forum – Indianapolis, IN - June 14, 2014

8. What about this? However, it has been very hard (!) to conduct the distance laboratory experiments, which require bulky and costly equipment The engineering technology programs are in the need of new technologies to adapt for distance laboratory instruction 8 Mert Bal, Assessment of Remote Laboratory Practices in Engineering Technology Distance-Education ASEE 2014 – International Forum – Indianapolis, IN - June 14, 2014

17. The Implementation Target Course: –ENT 407 – Modern Manufacturing Systems Delivered in hybrid format using IVDL, WebEx and Sakai. Covers a broad range of topics in manufacturing including: –manufacturing processes, modern manufacturing technologies, Industrial Robotics, Group Technology, Lean Manufacturing, CAD, and Concurrent Engineering (CIM). no laboratory exercises had been previously developed for this course VCIMLAB – A virtual reality-based robotics education software has been used for robot programming exercises 17 Mert Bal, Assessment of Remote Laboratory Practices in Engineering Technology Distance-Education ASEE 2014 – International Forum – Indianapolis, IN - June 14, 2014

18. Assessment Study An experiment has been designed and implemented for assessing the effectiveness of the remote lab system in distance-learning The main instruments used were: –Lab reports and Tests to evaluate the basic learning outcomes on robot arm manipulation and programming, –Qualititative surveys to obtain the feedback of the students about their overall experience in the laboratory. 18 Mert Bal, Assessment of Remote Laboratory Practices in Engineering Technology Distance-Education ASEE 2014 – International Forum – Indianapolis, IN - June 14, 2014

19. Test Groups GROUP 1: Local Students Traditional on-campus students who are physically present on the main campus of the university Local students can perform the lab using the physical equipment present in the lab GROUP 2: Distance Students Students that do not physically reside on the main campus. They connect to the main campus via IVDL Can perform the robot programming lab experiment by using the remote robot station via the internet. They must use the developed client-side software application and operate the robot arm while watching its movement through the web camera 19 Mert Bal, Assessment of Remote Laboratory Practices in Engineering Technology Distance-Education ASEE 2014 – International Forum – Indianapolis, IN - June 14, 2014

Quantitative Assessment Results GROUP 1 Local Students GROUP 2 Distance Students Grades for Robot Programming Lab Report 3.373.25 Grades of Test 23.353.09 21 No significant performance differences between the two groups The direct assessment results based on grades suggest that both student groups are getting similar learning experiences from the robot programming lab Assessment results of the test and laboratory reports are valid indicators that both groups grasp the subject matter Mert Bal, Assessment of Remote Laboratory Practices in Engineering Technology Distance-Education ASEE 2014 – International Forum – Indianapolis, IN - June 14, 2014

22. Conclusions For the initial study, results are fairly satisfactory to prove that there are not significant differences in student responses to working with remote and local equipment Qualitative survey results that the remote laboratory practice has somewhat a positive influence on the distance-learning students’ motivation We will continue monitoring students’ response and outcomes in other courses 22 Mert Bal, Assessment of Remote Laboratory Practices in Engineering Technology Distance-Education ASEE 2014 – International Forum – Indianapolis, IN - June 14, 2014
