Furniss and Parsonage (1977)
– About 40% of sixth form and college students thought that organic chemistry was the most difficult section of the syllabus in Kenya
Before 1999, ChemSense
Can be done better by drill & practice
Difficult for students with poor memorization
Require students to analyze the questions
Apply their knowledge into unfamiliar situations
Require conceptual changes in this areaAL Organic Chemistry in H.K.
Cognitive Conflict ChemSense
Computer or Technology
Computer-supported Collaborative Learning (CSCL)
Would students learn better in Organic Chemistry if they learn collaboratively with the help of ChemSense?
Results and Analysis ChemSense
The ChemSenset-value (N=9) that reflects the performance difference between the experimental groups and the control group in the pre-test, assignments and post-test.
Level of ChemSense
Interactivity = 3
Their discussion is mainly sharing information
Boys’ group has more collaborative work than girls’.
Boy’s group discussed for better solution.
(Phase II discussion)
1. CH3CH2CH2COCl H2/Pd/BaSO4/S CH3CH2CH2CHO (reduction of acyl chloride)
2. CH3CH2CH2CHO LiAlH4/ether H2O CH3CH2CH2CH2OH (reduction of aldehyde)
3. CH3CH2CH2CH2OH + CH3COOH CH3COOCH2CH2CH2CH3 (esterification)
3. CH3CH2CH2CH2OH + CH3COOH(c.H2SO4) CH3COOCH2CH2CH2CH3
