  1. Knowledge building in Chemistry K C Pun (punkc@mail.hongkong.com) SKH Tsang Shiu Tim Sec Sch

  2. Topics to cover • Knowledge-based society • Trends in education • KF as a tool to build up knowledge • Students’ reflections in using KF.

  3. Knowledge-based society • Principal’s remarks • Some “Nots” • Not eternal • Not limited by media • Not limited by age

  4. Trends in education • Learning to learn • Mastering 9 generic skills: • Esp. (to 05-06) • critical thinking skills • Creativity • Communication skills • Learning: • first order -> higher order

  5. Information to share (CUHK, 2002)

  6. A Joke? OR Reality!!! • 聯合國為全世界小朋友出了一道題目 「對於其他國家糧食短缺的問題 請你談談自己的看法.」 非洲的小朋友看完題目後不知道什麼叫 “糧食” 歐洲的小朋友不知道什麼叫 “短缺” 亞洲的小朋友不知道什麼叫 “自己的看法” 拉丁美州的小朋友不知道什麼叫 “請” 美國的小朋友不知道什麼叫 “其他國家”

  7. What do they infer? • Lack of these generic skills 思考及闡釋 記憶

  8. Chemistry = change • Change in syllabus => • Change in learning/teaching strategy • KF: as a tool to facilitate the change in strategy Interactions between students, teachers and environment

  9. Knowledge construction using forum (D/K) • Knowledge forum • HKU: CITE • How: • Divide F.4 students into groups • Give F.5 topics for F.4 students to discuss with guided questions

  10. KF in the school • Topics and guided questions • Air pollution • Nitric acid • Fertilizers • Sulphuric acid • Plastics • Ammonia • Petroleum

  11. Some good features of KF • Can insert diagrams • Can link up their concepts • Build up their own concept map • To change the ‘culture’ of students • Can even insert multimedia elements

  12. KF in practice

  18. Reflection journal

  19. Look at what they write: • Reflection journal • Second week in KF. • I want to know what is the differences between organic fertilizers and inorganic fertilizers. And what are their advantages and disadvantages. • I have posted a note about how to use fertilizers and a few notes about that role-play game. Also I reach my learning goal. • Still got some problems with searching information. But I begin got the technique. • I enjoy the role-play game. • I am unhappy about my lazy~

  20. What do they feel? • Students • Reflections • Fun • Learn from outside textbook • More efficient • Collaboration skills • Brainstorming

  21. Without KF – OK? • Why not? • KF is just a tool. • May use discussion forum in the intranet of the school.

  22. Discussion forum / others • May post the questions to the discussion forum and initiate their discussion • May even ask them to do as paper work

  23. Role of teacher inDF/ KF • As a facilitator • Not to answer question immediately • Not to correct their mistakes immediately • As a catalyst

  24. What will the “promoted F.4 students” do this year? • Choose a Chemistry topic in Integrated Science OR any topic in Certificate syllabus • Design 2 – 3 good questions • Set up their own criteria for assessment of good questions • Critics from members in the group and other groups • Game / Presentation after summer holidays

  25. What topics in IS? • The wonderful solvent – water • Matter as particles • Common acids and alkalis • Metals • Materials of the Modern World Etc.

  26. Why F.1-3 topics? • Students: Revisit the topics for consolidating their concepts • Teachers: Know what have been taught in lower forms • A continuation from junior secondary to senior secondary

  27. Why set questions? • Students know more if they can set up good questions • To have critiques among themselves • Know the great effort of teachers => may appreciate your effort in teaching

  28. Key to success • We have to be proactive. • BUT Before we act, • Better have support from your panel etc.

  29. Final remarks • KF is a tool. Others may apply. • There are many useful resources in the CDI’s web-site. • Project-based learning: • http://www.4teachers.org/projectbased/checklist.shtml
