  1. Happy Birthday Singapore 2011 Hwa Chong Institution 2011

  2. Objective : A : Authentic Task (Happy Birthday Singapore 2011) B : Balance (Routine and non-routine) C : Collaborative Learner ( Active Contributor)

  3. Outlines : • T– Teaching Ideas (Past ,Present ) • R– R2D2 • I – Innovation • G– Good Tools : VTI & Excel • O– Outcomes

  4. T – Teaching Ideas • Past (Experience) • Teacher –centered learning • Graphing of the various trigo. graphs on graph paper • eg. y = sin x , y = 2 sin x , y = sin (x + 45o), y = sin x + 3 • Present (Experiment) • Student – centered learning • Collaborative learners • R2 D2 ( Read – Reflect – Do – Display)

  5. R – R2D2 • Display : • Main Course (VTI GC Skills) • Demonstration • Guess the various graphs for these pictures • Read : • Starter ( Recap of standard Trigo. Grpahs) • Geogebraapplet • Transformation of the various graphs • Reflect : • Using Linoit to reflect effect a, b ,c and d on y = a sin (bx +c) +d • Sample Student Reflections • Do : • Main Course & Dessert • Create a design / picture Happy Birthday Singapore 2011 • Ferris Wheel (Ms Excel)

  6. I – Innovation Trigo. Online Lesson • Starter : • Collaborative learning in Linoit (student response) • Geogbra applet (visual impact) vs (manual sketching) • Main Course : • Skills involve in using the VTI • Problem solving (Mac laptop vs Laptop) eg. run the emulator for mac os • Transfer of knowledge to design a picture for Happy 46th Birthday Singapore • Dessert : • Application of the trigo. graphs knowledge to mathematical modeling of real-life activities • Ferris Wheel with MS Excel

  7. G – Good Tools • VTI : • Install / Download of the program • Running on Windows and Mac OS • How to use the VTI (GC) effectively? • Use of the WINDOW to set the domain and range • Readings on working with Style and Storing of pictures for design (Main Course) MS Excel : - Ferris Wheel - Dessert Template

  8. O – Outcomes • Task 1 :y = a sin (bx + c) + d • Online Applet • Offline Applet Task 2 :Guess the function of these designs.

  9. Task 3: Design a “Happy Birthday 2011” picture using trigo. functions Task 4: Transfer of their knowledge to real life application. (Ferris Wheel Problem)
