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

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

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”

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

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

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

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

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~

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

Without KF – OK?• Why not?• KF is just a tool.• May use discussion forum in the
intranet of the school.
![Page 22: Knowledge building in Chemistry K C Pun (punkc@mail.hongkong.com) SKH Tsang Shiu Tim Sec Sch punkc@mail.hongkong.com.](https://reader034.fdocuments.net/reader034/viewer/2022051416/56649e395503460f94b2a35f/html5/thumbnails/22.jpg)
Discussion forum / others
• May post the questions to the discussion forum and initiate their discussion
• May even ask them to do as paper work
![Page 23: Knowledge building in Chemistry K C Pun (punkc@mail.hongkong.com) SKH Tsang Shiu Tim Sec Sch punkc@mail.hongkong.com.](https://reader034.fdocuments.net/reader034/viewer/2022051416/56649e395503460f94b2a35f/html5/thumbnails/23.jpg)
Role of teacher inDF/ KF
• As a facilitator– Not to answer question immediately– Not to correct their mistakes
immediately
• As a catalyst
![Page 24: Knowledge building in Chemistry K C Pun (punkc@mail.hongkong.com) SKH Tsang Shiu Tim Sec Sch punkc@mail.hongkong.com.](https://reader034.fdocuments.net/reader034/viewer/2022051416/56649e395503460f94b2a35f/html5/thumbnails/24.jpg)
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
![Page 25: Knowledge building in Chemistry K C Pun (punkc@mail.hongkong.com) SKH Tsang Shiu Tim Sec Sch punkc@mail.hongkong.com.](https://reader034.fdocuments.net/reader034/viewer/2022051416/56649e395503460f94b2a35f/html5/thumbnails/25.jpg)
What topics in IS?• The wonderful solvent – water• Matter as particles• Common acids and alkalis• Metals• Materials of the Modern WorldEtc.
![Page 26: Knowledge building in Chemistry K C Pun (punkc@mail.hongkong.com) SKH Tsang Shiu Tim Sec Sch punkc@mail.hongkong.com.](https://reader034.fdocuments.net/reader034/viewer/2022051416/56649e395503460f94b2a35f/html5/thumbnails/26.jpg)
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
![Page 27: Knowledge building in Chemistry K C Pun (punkc@mail.hongkong.com) SKH Tsang Shiu Tim Sec Sch punkc@mail.hongkong.com.](https://reader034.fdocuments.net/reader034/viewer/2022051416/56649e395503460f94b2a35f/html5/thumbnails/27.jpg)
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

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

Final remarks• KF is a tool. Others may apply.• There are many useful resources
in the CDI’s web-site.• Project-based learning:
