Introduction
- Task into Test
- To obtain reliable test results
-
Time allocations for testing
- How much time to allocate for a test
-
Time constraint
- a good indicator of learners' proficiency in authentic situations
- Level of proficiency of the learners
-
The speed of the performance
- Less important when assessing the skills of beginning level learners
- the ability to use language according to normal time constraints
- Should not give Too much time for tests to assess language skills
-
Grading accuracy and time
- Tests - carefully costructed, edited, tried out and revised ==> For more reliability
-
Higher Reliablity
- Greater Accuracy of measurement
-
Assessing Grades
- Reliability +Accuracy
-
Can be enhanced by increasing the number of tests and/ or quizzes student take
-
Not to use time for testing when there is no need for the information test can provide
- Testing time reduces instruction time
- 1. Perfect accuracy, reliability are virtually impossible in educational measurement
- 2. Important decisions about students ==> Promotion should be always based on multiple indicators of performance
- 3. We must recognise the limitations of test-based measurement and be sympathetic to our students
-
Test instructions
- To let students know what they are supposed to do
-
It is to discover what students have learned
- Not how well they can understand test instruction
- Should be Clear and meaningful to students
- To inform clearly what to do for each kind of task including in the test
- to inform clearly what to do for each kind of task including in the test
- they should get enough information about the test as a whole to decide how best to expend their effort in the time available
-
General Instruction
- 1. Purpose of the test
- 2. Weighting of test
- 3. Time available
- 4. Number of parts or blocks
- 5. Special test conditions (referring textbook
- 6. kinds of input
- 7. kinds of response
- 8. extent of response
- 9. Procedure of recording response
- 10. What the assessor will look for when scoring
-
Block instruction
- to inform students of requirements of the task types
- 1. time limits for the block and for subsection within the block
- 2. number of marks allocated for the block
- 3. number of marks allocated to items within the block
- 4. special test conditions for the block
- Written or Oral
-
Suggestoins
- 1. when the students are already familiar with the task type, == elaborate instruction may not be needed
- 2. When we are using new test task, one example can do the job of pages of instructions
- If instructions are not good, the reliability and validity of students scores are invariably lowered
-
Layout and Format
- Aimed at helping students demonstrate their attainment of instructional objectives
- Directed towards removing distractions
-
Crowding
- Hard to read
- White space between instructions, questions
-
Ordering blocks of items
-
to help for each change of mental gears
- Saves time, energy
- Same kind of tasks or items should be kept together
-
Efficiency ordering
- Order the blocks = can gain the greatest number of points in the least amount of time eg: MCQ
-
Facility ordering
- order the block = can yield the best level of performance comes first
-
Difficulty ordering
- Opposite of facility ordering = students tackle the toughest tasks while they are freshest
-
Reactive ordering
-
if the performance on block A is likely to have an adverse effect on students' performance on block B, then put block B before A
- Eg: first Comprehension text, then comprehension questions
-
Ordering Items
-
Facility ordering
- Continue to order items according to your estimate of how well students will perform
-
Random ordering
- following the initial easy items, put the remainder in random order
-
Tips on scoring
-
Closed-ended test task can be scored easily and objectively
- Because the range of possible responses is limited and the scoring criteria are straightforward
- Limited-response tasks and especially open-ended test tasks are subjective and generally call for considerable judgment
-
Types of Scoring
-
1. Holistic
- A single score is assigned to a student's overall test performance
-
Holistic scores
- Represents teachers' overall impressions and judgments
- General incentives for learning
- Provides no detailed information about specific aspects of performance
- Not useful in guiding teaching and learning
-
2. Analytic
-
Different components or features of the students' responses are given separate scores
- eg: on an easy, spelling, grammar, organization, and punctuation
-
Score are sometimes added together to yield a total holistic score, but they are generally kept separate
- Performance or test profile
- provides useful feedback to students and diagnostic information to teachers
- Useful for planning instruction and studying
