Conventional to virtual laboratory in vocational education

  1. 1. Conventional to Virtual Laboratory in Vocational Education<br />Bernardus Sentot Wijanarka<br />Department of Mechanical Engineering Education Faculty of Engineering<br />Yogyakarta State University<br /><br />
  2. 2. Introduction<br />Laboratories and workshops on vocational education is the primary facilities in the formation of student competence. <br />On the other hand the operational costs to be paid to the implementation of practical learning is very high, so that vocational education institutions have problem in teaching and learning lab. <br />There is always a gap between the ideal and reality in teaching and learning in laboratories and workshops.<br />
  3. 3. In the standard facilities and infrastructure, the virtual lab standards have not been listed. Virtual laboratory is a laboratory clone obtained through the use of computers and software. According to Sahin, et al (2008) the main advantage of virtual media use in the training are: cost savings, safety, and access flexibility.<br />
  4. 4. Virtual reality as learning tools<br />It can be argued that the ultimate goal of education, at any level, is to prepare the learner with the skills needed to succeed in life (Aldrich, 2002). <br />Recent literature reviews of published research have consistently documented the effectiveness of virtual reality (VR) as a learning tool in a variety of settings. The research has shown that many educational institutions, industries, and organizations are now turning to VR to provide effective and cost-efficient ways of teaching and career preparation and development.<br />
  5. 5. Noe (2008) define the virtual reality as a computer based technology that provides trainees with a three-dimensional learning experience.<br />
  6. 6. Cost savingConvensional CNC Lab <br />HIGH cost<br />
  7. 7. Virtual CNC LabInterface of virtual CNC panels<br />Low cost<br />
  8. 8. Conventional lab<br />Facilities :<br />Machines (in large number, and many types)<br />Assecories (in large number and many types)<br />Tools (in many size, and shape)<br />Labs/ workshops buildings<br />requires huge funds for investment<br />
  9. 9. Virtual CNC lab facilities<br />
  10. 10. Student Learn how to operate CNC machine with real machine<br />
  11. 11. Virtual lab<br />Facilities:<br />Machine (one machine for each type)<br />Computers (network or stand alone) : desktop or laptop<br />Virtual software (one software for many type of machine)<br />
  12. 12. Learning With virtual machine<br />
  13. 13. safety<br />Real machine tools should <br />Should operate by expert/experienced operator <br />If work instruction is not followed, It have a risk of damaging expensive equipment and facilities or injury<br />Virtual machine <br />can operate by the students <br />No risk in operating the computer hardware and software<br />the students can experiment without risk of damaging expensive equipment and facilities or injury<br />
  14. 14. Acces flexibility<br />Conventional Lab:<br /> with limited lab hours and required supervision<br />Learning practice should be in lab building<br />Virtual lab :<br />easily accessible at any time without supervision and can be accessed via the Internet<br />Learning practice is anywhere.<br />
