Control Systems Tutorials

  1. 1. Control Systems Tutorials An online Flash application targetted at third-year engineering students to teach and demonstrate concepts of process control.
  2. 2. Presentation Overview <ul><li>1: Planning Process </li></ul><ul><li>2: Project Content </li></ul><ul><li>3: Online Application </li></ul><ul><li>4: Benefits </li></ul><ul><li>5: Future Developments </li></ul><ul><li>&quot;[It is] not simply the addition of knowledge but also the transformation of ways of understanding and organizing the knowledge learned.&quot; (Angelo, 1993) </li></ul>
  3. 3. Key Concepts <ul><li>FLASH </li></ul><ul><li>software that uses diverse and interactive multimedia (eg. animation or video) </li></ul><ul><li>LEARNING OBJECT </li></ul><ul><li>a simple, visual application that provides detailed, accurate, usable, and interactive information to a target audience </li></ul>
  4. 4. Camp CLOE, University of Waterloo <ul><li>C o-operative L earning O bject E xchange: </li></ul><ul><li>An instructional design and learning technology workshop </li></ul><ul><li>- Project Context: Who? What? Why? </li></ul><ul><li>- Project Management: Iterative and ongoing. </li></ul><ul><li>“ If you fail to plan, you plan to fail.” (K.I.S.S.) </li></ul><ul><li>- Project Definition: Scope statement. </li></ul><ul><li>- Project Plan: Keep the group profile, current scenario, and a Gannt chart nearby. </li></ul><ul><li>&quot;It is important for faculty to know something about how humans learn because teaching that ignores this knowledge runs the risk of being inefficient, ineffective, and sometimes even counterproductive.“ (Angelo, 1993) </li></ul>
  5. 5. Learning Objects <ul><li>Anyone can make an online textbook. </li></ul><ul><li>Why is a Learning Object so special? </li></ul><ul><li>- Consistent, predictable, intuitive - Interactive </li></ul><ul><li>- Engaging, motivational - Clear instructions </li></ul><ul><li>- Up-to-date or timeless - Evidence of effectiveness </li></ul><ul><li>- Assessment, meaningful feedback - Accessibility, multi-modal </li></ul><ul><li>Ask yourself: “Why is this better than what is already in use?” </li></ul><ul><li>“ The single most important factor shaping learning outcomes is the way in which students approach a learning task.” (Jackson & Anagnostopoulou, 2001) </li></ul>
  6. 6. Project Planning <ul><li>Stage 1: Research </li></ul><ul><li>Stage 2: Design Layout </li></ul><ul><li>Stage 3: Gather Data </li></ul><ul><li>Stage 4: Integrate with Flash </li></ul><ul><li>Repeat, using this as a model for the other tutorials. </li></ul><ul><li>“ In general it is the pedagogy that provides for learning, not the technology or the software alone.” (Carr, 1999) </li></ul>
  7. 7. Control Systems Tutorial Topics <ul><li>1: Basic Concepts </li></ul><ul><li>2: Stability </li></ul><ul><li>3: Tracking </li></ul><ul><li>4: Disturbance Rejection </li></ul><ul><li>5: P.I.D. Control </li></ul><ul><li>All have a simple, logical flow and use introductory concepts. </li></ul><ul><li>&quot;Students learn what they care about and remember what they understand.&quot; (Erickson, 1984) </li></ul>
  8. 8. Consistent Tutorial Structure <ul><li>- Text box </li></ul><ul><li>- Visual tools box </li></ul><ul><li>- Concept variables </li></ul><ul><li>- Concept views </li></ul><ul><li>- Quizzes for feedback </li></ul><ul><li>Multiple perspectives on topic provide something for everyone. </li></ul><ul><li>&quot;Educational Theory: Students learn by becoming involved. Students learn better when they can connect to the material in some way.&quot; (Astin, 1985) </li></ul>
  9. 9. Consistent Tutorial Structure <ul><li>Concept Views </li></ul><ul><li>- Video: 4 robotic models (designed by Quanser) </li></ul><ul><li>- Time: System response graphs </li></ul><ul><li>- Complex: S-plane diagrams </li></ul><ul><li>- Math: Simple manipulation of concepts </li></ul><ul><li>- More: Compare previous four views on one screen </li></ul><ul><li>An introduction to the topic begins each tutorial. </li></ul><ul><li>Quizzes provide immediate feedback on learning. </li></ul>
  10. 10. From Paper to Computer… <ul><li>Programming </li></ul><ul><li>- Flash and ActionScript Language </li></ul><ul><li>Video Integration </li></ul><ul><li>- Editing software </li></ul><ul><li>- Online streaming </li></ul><ul><li>&quot;Learning is not a spectator sport.&quot; (Chickering and Gamson, 1987) </li></ul>
  11. 11. Benefits of Application <ul><li>Students </li></ul><ul><li>- Extra learning resource outside the classroom setting </li></ul><ul><li>- Logical flow easy to follow, can compare to lecture notes </li></ul><ul><li>- Stimulates learning in multiple ways </li></ul><ul><li>- Learn at a comfortable pace, time for reflection </li></ul><ul><li>- Provides means of instant feedback on performance </li></ul><ul><li>Professors </li></ul><ul><li>- Can introduce in classroom as an extra teaching tool </li></ul><ul><li>- Different form of teaching addresses different learning styles </li></ul>
  12. 12. Benefits of Project <ul><li>What did we learn from this experience? </li></ul><ul><li>- Introduced to many project planning concepts </li></ul><ul><li>- Improved design layout techniques </li></ul><ul><li>- Interpersonal skills developed with interaction of coworkers </li></ul><ul><li>- Different perspectives provided different offerings </li></ul><ul><li>- Learned new software and a new programming language </li></ul><ul><li>All these techniques are useful not only in the workplace, but in planning and designing almost any large project. </li></ul>
  13. 13. Future Developments <ul><li>Where can we go from here? </li></ul><ul><li>Some proposed ideas for more tutorials: </li></ul><ul><li>State-Space Systems, Bode Plots, Root Locus Methods… </li></ul><ul><li>- Keep layout consistent to maintain familiarity </li></ul><ul><li>- Planning the model is already done! </li></ul><ul><li>“ There is still a lot to learn about how to get the best out of an evolving medium. In many respects it will probably always be a 'work in progress' given the rapid rate at which technology is progressing.&quot; (Hase & Ellis, 2001) </li></ul>
