These days there are many organizations, like OECD (Organisation for Economic Co-operation and Development) and IEA (International Association for the Evaluation of Educational Achievement), that organize international measurements of academic skills of children of certain ages on a certain time frame. The databases of these measurements are huge and they can offer versatile knowledge about the education systems and things that can affect student\u2019s ability to learn. On top of that, some of these databases are free to use for the public, increasing their usability in the field of research.\r\n\r\nThe bigger the databases get, the more likely it is for them to contain information that\u2019s not visible with just looking at the results or ranking them. During the past twenty years many methods and tools has been developed to analyze these kind of education oriented databases. All together these kind of methods and tools are called educational data mining. Usually the aim of educational data mining research is to either find new information from the used databases or to summarize the findings. Using educational data mining, researchers have managed to find out all kind of interesting information from the educational databases. Ranging from making predictions on students performance according their past results to figuring out if country stereotypes exists amongst PISA-data.\r\n\r\nIn this study I\u2019m going to apply K-means++ clustering algorithm to the PISA 2012 database and the unified TIMSS and PIRLS 2011 database in order to test if similar student profiles can be found from them. In order to keep the study in the frames of a master\u2019s thesis, I\u2019m going to focus only on the Finnish student results. The student profiles formed with the clustering were different between datasets, but they shared some features between each other and revealed some new knowledge to the field of research.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Lasse Wallden (lajuwall) on 2016-12-13 12:06:58.364644.
