9. Session: December 22nd

Erroneous examples: Find errors in proofs ( Session 7 ) --- Postponed

Exercises:

• Joint problem space: Compare all four approaches of last week's proof of the sum rule for limits. Generate a joint problem space. (**)
  

• Review: Select one of the following LeActiveMath chapters (in a language of your choice), read it thoroughly and write a review:
  
  • Functions and continuity
  • Difference quotients and derivatives
  • Derivation rules
  
  

  Did you find any errors? What did you like? What did you dislike? Is there anything incomprehensive and needs improvement? What kind of improvements do you suggest in general? And in particular? Are there any pictures missing? Where do you think an applet would be reasonable? Are more examples necessary? Would real-world examples help? Discuss in your group. Although this is a one star exercise, delivery is due on January 12th. (*)

• Since nobody did it so far: Sum rule for limits: different proofs ( Session 8 ) Who wants to present one of the different ways to do the proof should contact Michael Dietrich for coordination. (*)
  

• As result from our experiment today: Construct yourself a problem and its erroneous solution (a proof problem from analysis, but not necessarily a limit problem). Prepare a presentation in which you explain the principle solution idea (solution path) realized in your erroneous solution and what actually went wrong. (*)
  

• The Exercise Erroneous examples: Find errors in proofs ( Session 7 ) which I postponed in order to enable first our experiment today is open again! When you decide for this exercise, however, the focus of your presentation should be on its second part: ``Record your experience with the prototype. What did you like? What is not good? Make suggestions for improvement.'' (**)
