1 Chemistry & C S (Chemistry) SBA Teachers Conference (21 Oct 2017) 1

2 2 Supervisors Remarks Chemistry : students (433 schools) submitted SBA marks CS(Chem) : 850 students (66 schools) submitted SBA marks Moderation (statistical methods and professional judgment) Chemistry :59.4% of schools within expected range 25.2% of schools higher than expected 15.4% of schools lower than expected CS(Chem) : 62.1% of schools within expected range 19.7% of schools higher than expected 18.2% of schools lower than expected For those higher or lower than expected, majority only deviate slightly from expected range

3 General Remarks on SBA (1 of 2) Type of Assessment Tasks: V.A. for training and assessing basic skills for volumetric analysis Q.A. for training and assessing of thinking skills, simple tests on cations, and/or anions (minimum requirement) Note: Scope and depth of Q.A. need not be similar to those of the AL Chemistry Practical Examination. Should NOT include experiments like identification of functional groups of some organic compounds EXPT - similar to those suggested in the Curriculum and Assessment Guide, For Chemistry, they should be other than V.A. and Q.A. For CS(Chem), they should be other than V.A. 3

4 General Remarks on SBA (2 of 2) Products: Worksheet, quiz and brief / detailed laboratory report, etc. are all acceptable. Writing detailed laboratory reports is definitely a good training. Feedbacks to students - for facilitating students improvement. Students should be encouraged to reflect on / discuss with teachers to understand their own strengths and areas for improvement. 4

5 Assessment Students Written Works (Reports, worksheets, quizzes) Performance in Carrying Out Experiments Students Attitude Basic requirement of SBA Optional, recommended if deemed appropriate The related marks should be indicated clearly on the submitted students works samples Should NOT be assessed in SBA 5

6 More on Assessment Some observations for deliberations: Narrow mark distribution within a class Some extreme cases, most students got very high marks / most students got very low marks Recommendations: Use marking guidelines / marking schemes Teachers may modify the task requirements / worksheet items according to the general abilities of the students in a class, for example, add some challenging items for classes of more able students, or introduce some straight forward items for classes of less able / less motivated students 6

7 7 Still on Assessment Teachers can use worksheets from textbooks or tasks provided by publishers, but ensure the students cannot obtain the standard/reference answers before the SBA assessment modify the standard worksheets use other means to enhance validity and reliability Teachers can use quizzes ( SBA Quiz ), but the assessment items should closely related to a performed experiment.

8 Still More on Assessment Marks vs Grades Marks (10,9,8, 1) Preferred / Recommended Grades (A, B, C, Acceptable (need to have a mark-grade conversion tables) For schools with more than one chemistry classes: Teachers should perform school-based standardization, to standardize the SBA tasks and marking standards. Students in a school should be assessed on tasks of similar nature, complexity and required skills. 8

9 9 Remarks on Experiment List (1/2) Please use the template provided Teachers may use their own format, but please include sufficient amount of details for communication Include all the experiments performed, not only those assessed.

10 Remarks on Experiment List (2/2) Avoid Late submissions Incomplete list e.g. only titles of assessed experiments Include all experiments performed in the list Uninformative experiment titles E.g. QA01, VA01, EXPT05 10

11 11 Remarks on Scanned Reports Avoid Missing reports Missing pages in the scanned PDF file, e.g. all even pages were missing Only students answers on the worksheet, without details of experiments Advise your students to avoid faint handwritings e.g. pencils / light-green pens

58 OTHER COMMENTS 3a. Difficulties/challenges Insufficient time for practical activities / insufficient teaching time Students are weak in math, interest in science, knowledge of physics and biology, etc. Learner diversity

59 OTHER COMMENTS 3b. Suggestions for support and resources Videos of interesting experiments Organized and easily accessible resources for practical work and other resources Videos / animations for explaining some concepts Experiments with the use of mobile devices / microscale experiments e-learning resources STEM activities Teaching exemplars / other teachers resources for sharing Training courses on practical activities and e-learning Visits to lab for teachers/students

60 RECOMMENDATIONS 1. Minor amendments on the curriculum content and supplementary notes for Chemistry and Combined Science (Chemistry part) e.g. Delete C 60 at Topic VI(c), zinc-carbon cell at Topic VII(d), purification of copper at Topic VII(e) Topic V(c): Describe the steps involved in the monosubsitution of methane with chlorine using electron diagrams suitable diagrams or equations (e.g. CH 4 + Cl. CH 3. + HCl ) Views and comments on the updates will be collected via questionnaires
