In collaboration with useR!2014, upcoming 30 June – 3 July at UCLA, the Organisation for Economic Co-operation and Development (OECD has just announced the Programme for International Student Assessment (PISA) Data Visualisation Contest @ use!R 2014 is to show the potential of R for analysis and visualisation of large and complex data sets. PISA is a worldwide study developed by the OECD which examines the skills of 15-year-old school students around the world. The study assesses students’ mathematics, science, and reading skills and contains a wealth of information on students’ background, their school and the organisation of education systems. For most countries, the sample is around 5,000 students, but in some countries the number is even higher. In total, the PISA 2012 dataset contains data on 485490 pupils. This contest is meant to illustrate the wide range of possible analysis and visualisation tools that can be used with PISA and value will be placed on participants that are able to creatively use the strengths of the PISA dataset to submit creative analyses within one of the two areas identified. Submissions are welcomed in these two broad areas: Track 1: Schools matter: the importance of school factors in explaining academic performance. Track 2: Inequalities in academic achievement. One conference participant can submit only one submission per track. Submission should be related to the track topic. The prize for best visualisation in each track is 700 USD, with awards to be announced at useR!2014.
