SP Xpress analysis on ‘2011-2012
Primary 3 Third Exam Paper’
 SP Xpress analysis results:
 Type A: 20 items
 Type B: 1 item
 Type C: 1 item
 Type D: 3 items
 Let’s examine one item from each category (Type B, C,
D)
19
Exam item example: Type B
On which floor of the centre, can Grandpa find
presents for Jack?
A. 1/F B. 2/F C. 3/F D.4/F
20
Possible reasons for item being Type B
 Type B: Item is not difficult but requires amendments
because many students couldn’t answer it.
 Possible reasons:
 Item design flaws
 Not close to what teacher taught in class
 Students lack specific training in reading comic strips
21
Teacher examined the Type B item
 Students found it difficult because …
 Need to process and connect many ideas all at the same
time
Question
Comic strip
Which floor?
1/F,2/F,3/F,4/Ffloor directory
… of the Centre …
Star Shopping Centre
… can Grandpa find
presents …
We can buy all the gifts …
presents?
presentsrobotstoys(4/F)
… can Grandpa …
‘We’ refers to ‘grandparents’
22
Recommended solutions
 Increase students’ chances in reading English comic
strips in classroom teaching or leisure reading
 Teacher needs to illustrate more clearly in connecting
ideas
 Teacher needs to teach more explicitly which means
more visual demonstrations
23
Exam item example: Type C
In which step does Jack’s mum add
‘soy sauce’ and ‘wasabi’ to the sushi?
A. Step 1
B. Step 3
C. Step 6
D. Step 10
24
Possible reasons for item being Type C
 Type C: Item is difficult and requires amendments
because many students couldn’t answer it.
 Possible reasons:
 Confusing description
 Question misleading students
 Question containing error(s)
25
Teacher examined the Type C item
 Students did not have the relevant personal experience in
making and/or eating sushi
 The recipe did not mention dipping sushi into ‘soy sauce’ or
‘wasabi’ after the finish
 Without experience, students could not interpret the correct
answer which is the final step
 This question contains the error which requires outside
knowledge uncommon among the students
26
Exam
item
example:
Type
D
After cutting the vegetables and crab meat, Jack’s mum ____.
C.takes some rice wine vinegar and mixes it with the sushi rice
This is the answer but the
option rephrased the
instructions.
27
Features of Type D item
 Type D: Item is difficult and doesn’t require
amendments. It is suitable for screening the high
ability students. Low and mid- ability students can’t
answer it.
 Type D items should be kept at a low proportion in an
assessment.
 The rephrasing is difficult for students to interpret the
correct answer.
28
Analysis of TSA P.3 Reading Paper

assessment
 Compare the overall students’ ability from different years
 Examine the neglected elements in our teaching
 Assumption: TSA assessment covers the basic competency that
all students are supposed to have acquired by the end of a
learning stage

33
Personal reflection
Teachers become aware of the quality of the
assessments
1.

Accumulate professional experience in setting better
assessments
Teachers prepared for the unexpected and
unlearned
2.

Teachers become cautious and adjust their teaching
34
Things to do
 Suggest Ts reflect on their exam paper using
SP Xpress
 Facilitate Ts process the data with technical
supports
 Set up a school based question bank
 Nurture a culture on giving a more constructive
feedback to both Ts and Ss after assessment
