Slide15 : IF
-- Some Ss disappointed (results not expected),
… how to persuade work seriously
-- discussion (with parents ?)…..
THEN:
What count?? ….
… understanding “no pain, no gain”////
Suitable remedials : course materials of different Levels;

Strategy (5): after Assessment ….
[ initial, mid-, Final, Further ]
Self-Evaluation (as assmt tool before / after term test / exam) : Self-Evaluation (as assmt tool before / after term test / exam) let Ss check against the required aims/ objectives
Keep the checklist & give them after test/exam
< How to set….? >
May use the lesson objectives …
OR T/F questions about simple concepts
OR use Ss’ wrong phrases as stems…
Self-eval (2)…. Example T/F (concept analysis) : Self-eval (2)…. Example T/F (concept analysis) An aqueous solution of an ionic compound contains mobile ions.
All ionic compounds are soluble in water
Diamond and graphite are isotopes
When a covalent compound melts, the atoms in the molecules separate
Silicon dioxide is a giant structure held by van der Waals forces

Standard-referenced assessment: : Standard-referenced assessment: Based on the learning outcomes of the curriculum and report students’ results against a hierarchy of described levels of achievement based on typical performances of students at that level
Students’ results indicate their standards achieved in terms of knowledge, skills and understanding rather than in terms of the performance of other students taking the same examination
Elements of standard-referenced assessment: : Elements of standard-referenced assessment: A curriculum with clear learning outcomes
Descriptions of different levels of performance
Examples of tasks students are asked to do
Samples of students’ responses (exemplars)
Standards-setting
Format of reporting results
Slide26 : Finale…
With Best Wishes Hope you have a wonderful “Scheme of Work” & things be fine in coming days…
Slide27 : NO one sure of their capacities …Let’s exp’t!
Students:
need hard work to follow
K. cumulative
Lesson preparation (Thinking)
Maths Skills (Info Handling)
Personal Plan Teachers:
Design courses in small chunks: units of learning comprising content and activities
Plenty examples overseas: UK, US,..

Slide33 : Strategy (6) for Final Exam.. (before, after)
Some improve much over the 2nd Term….
All parties need to collaborate
(S+T Curriculum)
Some Groups work better …
a series of resources –
with associated tasks
Locating short
units of learning
commonly used formats for
easy checking
Discussions/tasks can be
face-to-face or online.
