2

Implementation schedule

• The detailed requirements, regulations, assessment criteria and guidelines are provided in the SBA Teachers’ Handbook (Trial Version) for HKDSE Technology and Living

http://www.hkeaa.edu.hk/DocLibrary/SBA/HKDSE/SBAhandbook-2018-Trial-TL-E.pdf http://www.hkeaa.edu.hk/DocLibrary/SBA/HKDSE/SBAhandbook-2018-Trial-TL-C.pdf

• During the transition years, the curriculum for Technology and living will remain as it is and schools are expected to conduct the SBA activities as an integral part of learning and teaching and internal assessment as recommended in the Curriculum and Assessment Guide.

Year of

Examination Implementation of SBA

2018 Optional Trial – Schools can opt to submit SBA marks for feedback from the

HKEAA. The marks submitted will not be counted towards the subject result.

Public examination results will constitute 100% of the final subject results.

Starting from 2019 Full Implementation – All schools will implement SBA and submit marks to the

HKEAA. The SBA marks will contribute to 30% of the final subject marks.

The Need for Moderation • Teachers know their students well and thus are best

placed to judge their relative performance within a school

• However, they are not necessarily aware of the standards of performance across all schools

• Moderation ensures the consistency of assessment standards across schools in order to achieve across-school comparability

• A common practice adopted by other examination authorities

9

Expert Judgment Moderation • Review of samples of students’ work

• Determination of school performance level on SBA and individual students’ moderated scores

• Follow-up on cases with extreme adjustments

Review of Samples of Students’ Work • Sampling (Stratified Random Sampling)

• Review District Coordinators/Assessors re-mark the samples with reference to the stipulated assessment criteria

10

Determination of School Performance Level and Individual Students’ Moderated Scores

• Average scores obtained in the sample review exercise are used to determine the group performance level of each school

• Statistical techniques will be employed to improve the reliability of the average scores, including: – appropriate adjustments made to schools’ average scores using ratio

estimation statistical techniques

– Adjustments made to the overall SBA performance of all schools (if deemed necessary) using Hierarchical Bayesian Modeling

11

Determination of School Performance Level and Individual Students’ Moderated Scores (Cont’d)

• An appropriate tolerance limit is set – If the difference between the school raw mean and that obtained

from the sample review is within the limit, the school raw mean would be used as the school performance level

– If the difference exceeds the limit, appropriate adjustments will be made to the school raw mean with reference to the sample review result to determine the school performance level

• Moderated score of each student is calculated in accordance with: – the school performance level, and

– the student’s relative performance within the school

12

Follow-up on Cases with Extreme Adjustments • For each school, the moderated scores will be compared

with the raw scores

• If the difference between the two is prominent, may modify the adjustments recommended by expert judgment to properly reflect students’ performance

Impact of Expert Judgment Moderation • Similar to statistical moderation because they share the

same underlying principles

• Ranking of students within a school remains unchanged
