CEM IBE CABT (Computer-adaptive baseline testing)
Who are CEM? The Centre for Evaluation and Monitoring Part of Durham University (not for profit) Largest educational research unit in a UK university (so informed by evidence from research) Established in 1983 Provide confidential assessment and monitoring information Currently assesses over one million students worldwide each year
What is CEM IBE? Centre for Evaluation and Monitoring International Baccalaureate Evaluation Provides assessment and monitoring information for use at institution, department, subject and individual level Provides performance indicators Its sample size guarantees more reliable, accurate data (over 2000 schools in 48 countries worldwide)
Why use CEM IBE? To
support professional judgement To monitor student intake To assist in the process of student targetsetting To monitor student progress To interpret value-added performance To measure school level performance over time
What assessment and monitoring information do we receive? Information is in the form of performance indicators. They are: Baseline scores (measures) – assessment of student skills and developed abilities ‘Predictive data’ – indicators of potential end of course achievements Value-added data – a measure of relative performance in exams linked to baseline measures
What is the process/timeline? Register for the assessment
Administer the Assessment (CABT) and submit student data – Post course selection Grade10/Early Grade11
Receive Predictions
Submit Exam results for analysis – July of Grade 12 academic year
Receive Value-Added Reports - September
What is the Computer Adaptive Baseline Test?
It measures the student’s developed skills and ability (at that point in time) It is adaptive, adjusting to the responses of the students, giving harder or easier questions as appropriate The test is designed under three section headings: 1. 2. 3.
Vocabulary - assessing fluency Mathematics - covering a wide range of numerical concepts and manipulations Visio-Spatial (non-verbal) assessing perceptual speed and accuracy
CABT - Exemplars
A demonstration test is available at the following address: https://www.intuproject.org/demos/secondary/demobaseline.html (click Yr 12/13 + under the ALIS heading, then click ‘If you are running a demonstration please click here to continue’
CEM IBE - Summary
The results/feedback from CEM IBE are completely confidential. It will not be seen by any universities, nor by the IB (only AISJ staff, students and parents will ever see it) Computer Adaptive Baseline Test provides information on a student’s ‘Ability’, NOT their current IB performance nor what they will get in their final grade (but it is very accurate in this respect) With consistent effort/application and teacher expertise, value will be added to the ‘raw ability’ and baseline expectation will be exceeded. Conversely with very little effort/application baseline expectation will not be achieved
CEM IBE – Summary (continued)
It can also be used as a supplementary piece of evidence used in formulating grade predictions and projections. Predictions’ and Chances Graphs indicate typical (not actual) attainment and are subject specific
