Teaching and testing – the terrible twins
“Evaluation and responsibility in the student-centred classroom”
How to give a useful grade in a student-centred classroom: quantity as a guide to improvement.
Like many teachers I've administered a lot of tests and I continue to "give a grade" to my students. Although I “don't believe in testing” I think I've found a way around the problem of tests and giving grades in classes (proficiency testing is a different issue). This paper will question a few values and make a few suggestions. The manner in which I give the workshop will allow the participant to experience the type of classroom where the solutions I propose can best be applied.
A. Language education: creativity or conditioning
I have a few problems with conventional testing – and teaching!
Approach to testing reflects approach to teaching
Washback effect – both ways
Teaching as ‘heavy learning’ / ‘light learning’
Teacher centred, receptive learning, authority invested in teacher
Student centred, creative learning, student controls own learning
Teaching so student learns what someone else knows / teaching so student discovers what they know
Teacher as source of knowledge, transmission, student receiving – testing to determine if reception is accurate
Teacher imparts knowledge but student has time to work out own position – cannot be directly tested, no limit to student knowledge
Classroom creates society – as in CR so in workplace etc
Only one person in CR is active, creative, self-directing
Only those who follow the rules and rise to the top can say how things are done
Each person has equal share of activity, creativity, direction
Makes use of creative potential of all members
Testing – ‘the art of precise uncertainty’
Apparent precision of exact grade
Even publicly prepared tests have very wide error range
Look good but in fact very vague
See below on test error
B. Testing stops learning
Purpose of testing (exams) is to create/perpetuate a social hierarchy
Is this what you want? – NB this is what you are doing!
Purpose of testing is to promote accuracy
But testing looks for errors (psychology of teacher testing)
Testing tests what student does not know
Testing is always limited
Only tests within certain strict limits
How can you test open ended knowledge
Can a test test what the student knows?
Including what the teacher does not know
What type of teaching can increase learning
How can testing (evaluation) help learning
The teacher: always testing
Looking for error and correcting = “the testing tic”
You can recognise a teacher a mile off
Always correcting you
Testing is the requirement of accuracy
Teacher looks for mistakes, not for genius
Continual correction blocks creativity, encourages conditioning
Do it the way you are told
Teacher, don’t correct
In order to facilitate communication, the teacher should avoid making individual corrections. Fluency requires the freedom to make mistakes.
Space for responsibility and personal involvement
Alternate teacher direction: teacher as centre
And student interaction: teacher silence
Principle rule: don’t correct
Difficult to pass up on chance to correct an error
Ethos of education: accuracy, and evaluation
Student expects it!
Preoccupation with accuracy hinders fluency
Fluency at heart of communication
Effect on future society of continuous teacher correction
Expectation of authority and lack of creativity and responsibility
Observe errors but comment to whole class
Avoid commenting to an individual
Leave freedom to experiment, even to ‘misunderstand’
Develop capacity for independence and creativity
C. Standard forms of evaluation
Testing proficiency: how good is the student
Absolute proficiency: how good is a student at the end of the course
Penalises those who study hard but have lower initial level of proficiency
Relative proficiency: how much has a student improved during the course
Very difficult to measure a small increment in proficiency over a short period
Testing performance: how well does the student ‘perform’ during the class
Measures of performance not very reliable
Ad hoc teacher tests have little chance of being accurate
Given that professional pre-tested tests have wide ‘error of measurement’
The description is not the language (Magritte – “This is not a pipe”)
Grammar: testing the description – grammar is not the language, it is (one) contrived description of the language
Communicative: testing the use of the language – in a contrived situation
How can we test creative thinking and discovery (in the L2)??
How can I give a useful grade when I want to avoid testing?
Evaluation which does not interfere with learning
Test what the student knows, not what they don’t know
Avoid teacher interference in student’s learning
Create sense of responsibility for one’s learning
Promote creativity and insight
Involving student in evaluation – approaches to classroom management
A system of partial self-evaluation can increase the student’s involvement and sense of responsibility.
Involvement in self-evaluation
Student direction of own learning
Most classroom activities imbued with deep sense of unreality
Self-evaluation is real – and can involve L2
D. “If a student works, they will improve”
Quantity as a measure of quality
Tests use quality – how good a student is at …
This is difficult to measure accurately, and creates hierarchy of power
Hypothesis/observable fact in the classroom
The amount of work a student does is a fair reflection of what they learn during the class
If a student does little, they learn little, if they do a lot, they learn a lot
Quantity is easy to measure
Can be done by the student
Gives student control over own learning
Student is aware of involvement in class and can choose to change
Student controls grade
Can choose grade based on how much is done
If ongoing grade is too low during semester, can go back and do extra work before end of semester
Testing will not stop because I have written this paper
Know how to test as well as possible
Know the limitations of testing
Use it to do what you want to do
Know when not to use testing
When you don’t want to achieve what testing achieves, look for/create something else.
What type of teaching can best implement this type of evaluation?
Plain Pair Group Teaching (Plain PGT) is designed to put in practice what has been presented in this paper
The Art of Precise Uncertainty
All test scores are approximate. It is important to know just how much approximation is built into any test we use, otherwise we risk making assertions based on a test score which the test makers themselves consider incorrect.
There are two ways of looking at test error:
(a) When can I say that a student’s score represents their “true” score? – Standard error of measurement (SEM)
(b) When can I say that one student’s score is higher or lower than another student’s score? – Standard error of difference (SEdiff)
There are two (or three) levels of confidence, i.e how many times can I be wrong in comparing a student’s (a) or students’ (b) scores and still say “it doesn’t matter”.
1 Standard error = 67% i.e. I will be wrong one time in three.
2 Standard errors = 95% i.e. I will be wrong one time in twenty.
3 Standard errors = 99% i.e. I will be wrong one time in a hundred
For each test purpose, we need to judge how many times we can make a mistake in evaluating a student and still say “that is acceptable”. For example if we say being wrong for 33 students in 100 is unjust, then we need to choose a 95% level of confidence - where we will still make a mistake for 5 students in 100 – or higher (99%) if absolutely necessary.
TOEFL (scores 300-670)
1 SEM = +/- 14 points (from test booklet)
(the following are a personal guestimate by statistical extrapolation)
2 SEM = +/- 28 points
1 SEdiff = +/- 19 points
2 SEdiff = +/- 38 points
3 SEdiff = +/- 49 points
This means we cannot confidently tell the difference (at 95% confidence) between students whose real score may be 500 but will score between 462 or 538. Anywhere between 462 & 538 is “the same score”. In addition, in comparing 100 students whose ‘real’ score is 500, 5 will score down to 451 or up to 549 - and one will still be beyond those scores.
NB This is what happens when we have a ‘cut-off point’ on TOEFL scores for inclusion and exclusion e.g. for a scholarship, often with a difference of one or two points. We have almost no chance of avoiding injustice.
