  1. LAB@HOME for analog electronic circuit laboratory Vahé NERGUIZIAN1, Radhi MHIRI1, Maarouf SAAD1, Hamdjatou KANE2, Jean-Sébastien DESCHÊNES3, Hamadou SALIAH-HASSANE4 1 École de technologie supérieure 2 Université du Québec en Outaouais 3 Université du Québec à Rimouski 4 TÉLUQ

  2. PLAN OF THE PRESENTATION At distance communication and collaboration Laboratory Kit @home • Objectives of FODAR project • Principle of Lab@home • Lab@home process description and resources • Lab@home Implementation of the approach • Pre-Lab@home • Lab@home • Post-Lab@home • Advantages, drawbacks, recommendations and conclusion FODAR: Academic Development Fund ‘Université du Québec’ Network

  3. OBJECTIVES OF FODAR PROJECT • To develop each student’s personal, professional and social qualities with the laboratory experiments • To facilitate students with a higher flexibilityin scheduling the lab experiment time periods • To permit students in using more efficiently the ICT for laboratory experiments • To alleviate university'spurchasing of highly cost equipment

  4. LAB@HOME PRINCIPLE (1) • Miniaturized kit • Software (Waveforms) • Source AC • Source DC • Oscilloscope • FFT Source Oscilloscope

  5. LAB@HOME PRINCIPLE (2) • At distance • In presence • Collaborationwith colleagues • Instructor intervention

  6. LAB@HOME PROCESS (1) • Kits must be supplied by institution or be bought by students • Studentsmust feel comfortable with computers and kit before starting the lab • Adequate preparation of documentation by Professor • Well defined Lab@home procedure by Professor • Pre-Lab@home (preparation for the experiment) • Lab@home (experiment) • Post-Lab@home (finalisation of the report) Note: Sustainability of the kit

  7. LAB@HOME PROCESS (2) • Pre-Lab@home (preparation for the experiment) • To take a virtual tour, ensuring that student masters basic prerequisites and discovers specific used hardware • Lab@home (experiments) • Student will be connected in real time to the lab kit conducting remote experimentation. Time required for this stage is very critical and it must be minimized to allow all students handling experiments in turns • Post-Lab@home (finalisation of the report) • Student will analyze results and submit final report

  8. RESOURCES • Appropriate miniaturized kit containing miniaturized equipment and the flexibility to create electric and electronic circuits through physical components • Appropriate efficient internet based communication interfaces to all users • Good information exchange and communication between students and laboratory instructor (documentation)

  9. LAB@HOME IMPLEMENTATION (1) • 5 Lab@home case study were created on different subjects related to diodes, Op-Amps and transistors • Pedagogical approach was used to describe each case study/experiment • Each team ensured the realization of the case study: • At distance from the kit (circuit components already mounted on the kit) • In presence with the kit (circuit components mounted by the team on the kit) • Link/bridge was created via internet with TeamViewer • The team was connected to the kit via internet(at distance or in presence with the kit)

  10. LAB@HOME IMPLEMENTATION (2) • Experiment initiator can give control to other colleagues. They can manipulate with the complete set-up alive in real time and both can observe changes brought during the manipulation • Team manipulated with the circuit parameters and observed the variations (amplitude and frequency variation, …) • Each case study of 45 minutes maximum was elaborated by students during project based approach laboratory session of 4 hours • Lab@home consolidates the theoretical knowledge seen in the class

  11. LAB@HOME IMPLEMENTATION (3) At distancefrom the kit In presence with the kit

  12. LAB@HOME IMPLEMENTATION (4) Pedagogical Approach Theory in class (ppt, video, examples) Project based approach Laboratory Consolidate Competences Consolidate Knowledge Lab@home Case study

  13. LAB@HOME NATIONAL & INTERNATIONAL • Kit already populated with components at ETS • Experiment initiator at ETS gives control to other national and international colleagues • Example of passive filter response • Effect of: • Input frequency change • Input amplitude change • Other changes (waveform, etc.) • They can manipulate with the complete set-up alive in real time and all parties can observe changes brought during the manipulation

  14. LAB@HOME ADVANTAGES • For students • Bring student’s motivation in apprenticeship • Permit students to become more autonomous in creating new ideas • Sensitize and consolidate student’s scientific and professional responsibility • Permit students having flexible schedule, better organization and planning • For the Professor/laboratory instructor • Create a satisfaction/motivationto support students with advanced ICT • Permit better online communication between students/Professor/labinstructor • Allow a better follow up of student difficulties and advancement by the Professor/laboratory instructor. • For the academic institution • Reduce purchasing of high costly equipment • Liberate some physical space in the lab • Allow students and instructors to use efficiently ICT tools • Have institutional visionaryapproach and follow the 21th century ICT trend.

  15. LAB@HOME DRAWBACKS • For students • No touch with real heavy equipment • Psychologically used for classical approach • With new approach defensive and rejection • Removal human contact between students and laboratory instructors • Students like to learn from errors made by their colleagues • Communication difficulties between the colleagues due to Internet • Reducing student’s retention if approach seen negative by them • More time demanding from student • For the Professor/laboratory instructor • Disturbing Professor/lab instructor classical mentality • More time demanding for Professor

  16. LAB@HOME RECOMMENDATIONS • Communication link very important for the success of Lab@home • Degradation of quality of pins on the kit due to misappropriate usage by students (verification) • Good prepared documentation • Consideration of students’ profile • Completely different instructor role. Change of philosophy

  17. CONCLUSION • Full mobility of laboratory experiments at distance or at home • Collaborative work supported to improve effectiveness of learning • Lab@home experience can show (student) • Increased autonomy • Good communications and e-cooperation • Increase creativity and motivation • Advancement knowledge and competences. • Lab@home pilot project (ELE200 course) outcome: • Well prepared documentation (+++) • Students are motivated and satisfied (+++) • Time consuming for students (---) • Encouraging pilot project experimental initial results. Further experiments will permit enhancement of Lab@home concept • Particular attention is given pedagogical approach using the Problem Based Learning (PBL) approach reinforced by description of authentic industrial problem and supported by laboratory miniaturized tools or kits
