Reasoning with evidence : new opportunities in assessment.

Ridgway, J. and McCusker, S. and Nicholson, J. (2006) 'Reasoning with evidence : new opportunities in assessment.', 7th International Conference on Teaching Statistics Salvador, Brazil, 2-7 July 2006.


Computers facilitate reasoning with complex data. We report a study where 195 students aged 12 to 15 years were presented with computer based tasks that require reasoning with multivariate data, together with paper based tasks from a well established scale of statistical literacy. All the tasks fitted well onto a single Rasch scale; computer tasks were cognitively more complex, but ranked only slightly more difficult than paper tasks on the Rasch scale. Implications for assessment, the curriculum, and public presentations of data are discussed.
