1 Yr 12 Parents Forum:ALIS dataWest Island SchoolNovember 2012
2 ALIS Advanced Level Information System Run by Centre for Evaluation and Durham University.29 years worth of data.1.3 Million Students in CEM systemAbout 10K students per year doing IB, mainly international schools and UK independent schools.
3 Basic Principles of ALIS Data Measure Student’s abilityIntake ProfilesIPR - Strengths and Weaknesses, provides valuable information to support teaching and learning of individual students.Project future performance from national trendsChances Charts, target setting and subsequent monitoring.We do not use to predict future grades for University or IB predictors.Compare actual performance to Projected PerformanceValue-Added Reports. Used to assess performance of our school.
4 ALIS : CABT TestingAssessed by a computer adaptive test that takes 1 hourMeasures developed ability rather than taught curriculumNo preparation is required for the testComponents arevocabulary (words and phrases)maths (numeracy)non-verbal (spatial/3d)School and students’ test performances are compared to students around the word.
5 Computer adaptive?Questions get harder when a the student answers a question correctly, vice versa
6 VocabularyVocab - Closely related to reading and English – a proxy – pupils need to be able communicate ideas across the curriculum areasVocab is caught not taught – absorbed from the world around us. On its own is an excellent predictor for later academic achievement. Contributes well to the prediction ofEnglishHistoryForeign LanguagesChoose word or phrase with most similar meaning from those shown on right.How is vocab relevant to my subject?6
7 Mathsx/4 + 2And a hard question – could you do this? Seems tricky – especially for 11 year olds! However 1 in 15 pupils are getting this right!Good maths skills will mean that any areas of the curriculum that require numeracy - the pupil to think logically, perform calculations, reading dataMaths – here’s an item of medium difficulty.Good predictor ofMaths#StatsICTD&TEconomics7
8 Non-Verbal: Cross-sections Non verbal – 3D visualisation, spatial awareness, pattern recognition. NV consists of 3 sections – crss sections, block counting, pictures.A low score here will mean that students will struggle will any elements of the curriculum that needs them to be able to think in 3 dimensions –for examplegeography,ArtDramaMathsScienceD & TSolid been cut with plane to form a cross section.8
9 Non-Verbal: Blocks2Piles of blocks number of small and large blocks9
10 Non-Verbal: PicturesPictures – addition, subtraction, sequences of pictures.Low scores in Non verbal – anecdotally number of times PH has been told on INSET that low NV corresponds to observed problems in D&T.10
11 C B D A Bands, percentiles, standardised scores… Standardised scores Standardised to include:25% of students in each band50% betweenMean score 100CBDAStandardised scoresPercentiles:105203014090958070996050
22 Regression curves from past results used to make predictions for future results
23 Regression Curves for HL Subjects: it is ‘easier’ to get a higher grade in some subjects
24 Sample Chances ChartsThe 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 topNote: GCSE grades are converted into numbers A*=8, A=7, B=6, etc.
25 GCSE predictions similar to CABT test predictions – as expected
26 GCSE predictions above CABT test predictions – hard working student ?
27 GCSE predictions below CABT test predictions – underperformed at GCSE?
