Ensuring Fairness
3
Principles of Fair Analysis : 1.Use an Appropriate Baseline 2.Compare ‘Like’ with ‘Like’ 3.Reflect Statistical Uncertainty

CEM Systems Principle of Fair Analysis No1 : Use an Appropriate Baseline
5
The Projects Year 7 Year 8 (+ additional) Year 9 MidYIS Computer Adaptive Baseline Test or paper-based test Year 10 Year 11 Yellis Computer Adaptive Baseline Test or paper-based test Year 12 Year 13 Alis GCSE Computer Adaptive Baseline Test (paper test also available) GCSE A / AS / Btec / IB etcINSIGHT Combines curriculum tests with developed ability KS3KS4
6
The Assessments Year Groups WhenDeliveryIncludes MidYIS 789789 Term 1 + catch ups Paper or Computer Adaptive 1 session Developed Ability Vocabulary Maths Non Verbal Skills Yellis 10 11 Term 1 + catch ups Paper or Computer Adaptive 1 session Developed Ability Vocabulary Maths Non Verbal INSIGHT 9 4 week testing window mid April – mid May + catch ups Computer Adaptive 3 or 4 sessions Curriculum-based Reading Maths Science + Attitudes & Developed Ability
7
The Assessments INSIGHT – curriculum-based Assessment Maths - Number & Algebra - Handling Data & Space - Shapes & Measures Science - Biology - Chemistry - Physics - + Attitudes to Science Reading - Speed Reading - Text Comprehension - Passage Comprehension Additionally for INSIGHT: Developed - Vocabulary, Ability Non verbal, Skills - Attitudinal measures

What is Computer Adaptive Assessment? Questions adapt to pupil Efficient No time Wasting Wider Ability Range More Enjoyable Green The Assessments
9
Computer AdaptivePaper-based Number of Students per Test Session Limited by number of computers available – multiple testing sessions Can test all students in a single session (in hall or in form groups) or in more than the one session Cost Roughly 30% cheaper than paper-based test Standard cost Processing of Baseline Feedback Baseline feedback available within a couple of hours of testing Takes around 2-4 weeks for papers to be marked Preparation Must be able to install the software or access the internet version of the test No pre-test set up Student Experience “Tailored” assessmentAll students see all questions, irrespective of suitability Computer-adaptive vs Paper-based testing

The Analysis

Some Subjects are More Equal than Others…. Principle of Fair Analysis No2 : Compare ‘Like’ with ‘Like’ 1.5 grades’ difference!

Baseline Assessment and Predictive Feedback
23
Baseline Feedback Nationally-Standardised Feedback How did your pupils perform on the assessment? What strengths and weaknesses do they have? As a group how able are they? Predictions Given their performances on the test, how well might they do at KS3 or GCSE?
24
Baseline Feedback Feedback can be used at the pupil, class and cohort level. - to guide individuals - to monitor pupil progress - to monitor subject-wide and department level progress For classroom teachers, Head teachers or SMT as a quality assurance tool. Data can be aggregated at other levels. We support & provide software tools to help schools to do this e.g. Paris software.
25
Baseline Feedback – Test Scores
26
· National Mean =100, Standard Deviation =15 · 4 Performance Bands A, B, C, D · Averages & Band Profiles for the cohort · 95% of scores lie between 70 & 130 · No ceiling at 130+ or floor at 70

34
Predictive Feedback- Individual Chances Graphs 30% chance of a grade D – the most likely single grade. 70% chance of a different grade Point Prediction = 3.8 Chances Graphs based on Pupil’s actual Test Score NOT Band
35
Chances Graphs The Chances graphs show that, from almost any baseline score, students come up with almost any grade - - - there are just different probabilities for each grade depending on the baseline score. In working with students these graphs are more useful than a single predicted or target grade Chances graphs serve as –a warning for top scoring students and –a motivator for low scoring students
36
Value Added Feedback
37
For each subject, answer questions: Given their abilities, have pupils done better or worse than expected? Can we draw any conclusions at the department level?
38
Value Added Feedback For each pupil in each subject: Raw residual = Achieved – predicted Standardised residual – allows fair comparison between different subjects and years At subject level: Confidence bounds are narrower with more pupils If average standardised residual lies within bounds you cannot draw any conclusions If average standardised residual lies outside bounds you can be confident that something significant is happening in that subject.
39
Burning Question : What is my Value-Added Score ? Better Question : Is it Important ? Principle of Fair Analysis No3 : Reflect Statistical Uncertainty Value Added Feedback
40
Value Added Feedback – Scatter Plot GCSE English GCSE Points Equivalent Baseline Score Look for Patterns… General under- or over-achievement ? Do any groups of students stand out ? – high ability vs low ability ? – male vs female ?
41
Value Added Feedback Year 7 Pupil Level Residuals to GCSE
42
Value Added Feedback – Standardised Residuals Graph Standardised Residuals shown with confidence limits at 2 (95%) and 3 (99.7%) standard deviations Standardised Residuals can be compared fairly between subjects and over years

Attitudinal Surveys
45
Attitudinal Feedback Your data is above the average Your data is below the average Your data is about the same as the average
