Yr 12 Parents Forum: ALIS data West Island School November 2012 ALIS Advanced Level Information System Run by Centre for Evaluation and Monitoring @ Durham University. 29 years worth of data. 1.3 Million Students in CEM system About 10K students per year doing IB, mainly international schools and UK independent schools. Basic Principles of ALIS Data Measure Student’s ability Intake Profiles IPR - Strengths and Weaknesses, provides valuable information to support teaching and learning of individual students. Project future performance from national trends Chances Charts, target setting and subsequent monitoring. We do not use to predict future grades for University or IB predictors. Compare actual performance to Projected Performance Value-Added Reports. Used to assess performance of our school. ALIS : CABT Testing Assessed by a computer adaptive test that takes 1 hour Measures developed ability rather than taught curriculum No preparation is required for the test Components are vocabulary (words and phrases) maths (numeracy) non-verbal (spatial/3d) School and students’ test performances are compared to students around the word. Computer adaptive? Questions get harder when a the student answers a question correctly, vice versa Vocabulary Maths x/4 + 2 Non-Verbal: Cross-sections Non-Verbal: Blocks 2 Non-Verbal: Pictures Bands, percentiles, standardised scores… Standardised to include: 25% of students in each band 50% between 90-110 Mean score 100 C B A D 0 50 60 70 80 90 100 110 120 130 140 Standardised scores Percentiles: 1 5 10 20 30 40 50 60 70 80 90 95 99 150 Intake profile for current Year 12 at WIS Example IPRs: Average WIS student Example IPR: low non verbal Example IPR: high maths and NV future Engineer or Architect? Example IPR: relatively high nonverbal Example IPR: relatively low maths Example IPR: reletively low nonverbal Example IPR: gifted student Regression curves from past results used to make predictions for future results Regression Curves for HL Subjects: it is ‘easier’ to get a higher grade in some subjects Sample Chances Charts • The following charts show the percentage of students, who achieved the same baseline score as your children, went on to score a particular grade at IB. • It is not meant to predict what grade your children will achieve, but is an indication of how previous students of similar ability performed in that subject. • Two baselines are used. (LHS) Average GCSE score, (RHS) ALIS (CABT) test score. • The black line shows the average score achieved by students of similar ability, this is shown as ‘predictions points’ in the table at the top Note: GCSE grades are converted into numbers A*=8, A=7, B=6, etc. GCSE predictions similar to CABT test predictions – as expected GCSE predictions above CABT test predictions – hard working student ? GCSE predictions below CABT test predictions – underperformed at GCSE?
