Topics to cover • • Knowledge-based society Trends in education KF as a tool to build up knowledge Students’ reflections in using KF.
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 ”
What do they infer? • Lack of these generic skills 思考及闡釋 記憶
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
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

Reflection journal
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.
Discussion forum / others • May post the questions to the discussion forum and initiate their discussion • May even ask them to do as paper work
Role of teacher in DF/ KF • As a facilitator – Not to answer question immediately – Not to correct their mistakes immediately • As a catalyst
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
What topics in IS? • The wonderful solvent – water • Matter as particles • Common acids and alkalis • Metals • Materials of the Modern World Etc.
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
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: – http: //www. 4 teachers. org/projectbased/checklis t. shtml
Thanks!!!
