Web-based Virtual Laboratory Assistant for Circuits LaboratoryFirdous Saleheen, Salvatore Giorgi, Zachary Smith, Vira Oleksyuk, and Chang-Hee Won* Department of Electrical and Computer Engineering Temple University 1947 N. 12th Street, Philadelphia, PA 19122 Voice: (215) 204-6158 Fax: (215) 204-5960 *Corresponding Author, E-Mail: firstname.lastname@example.org Submitted to the 2015 American Society for Engineering Education (ASEE) Annual Conference and Exposition NSF Grantees’ Poster Session Temple University, Philadelphia, PA October 10, 2014 Abstract A virtual laboratory assistant (VLA) software will provide personalized instruction forstudents participating in a self-paced undergraduate circuits laboratory. VLA will allow studentsto work in the open laboratory even a teaching assistant is unavailable. The system’scomponents include pre-lab testing and instruction, engineering design exercises, short topicexplanation videos, instrumentation instruction (including safety), and a corresponding post-labtest module. This web-based VLA software will guide a student for circuit simulation andhardware laboratory. VLA will also answer frequently asked questions that the student mighthave during the lab. Furthermore, VLA can guide the students in building, verifying, andtroubleshooting a circuit simulation by utilizing a circuit recognition algorithm. This algorithmuses image processing to recognize the circuits for simulation. The preliminary results show thatthe circuit recognizer module can identify the RLC circuits. This approach will ultimately useless resources and add flexibility by using fewer teaching assistants and less dedicated space,both of which are important administrative benefits. The merits of our open laboratory approachinclude (1) individual, self-paced learning is possible, (2) 24/7 accessibility, (3) shy or moretimid students can receive personalized instruction in a non-threatening environment, and (4)increasing the level of engagement by allowing students to freely explore the subject matter.Because of these advantages, we hypothesize that the students who learn in an open labenvironment will perform better than in a traditional closed lab. In this poster, we present theVLA software and the preliminary results of pre- and post-lab assessment.
