Students' performance on programming-related tasks in an informatics contest in Finland, Sweden and Lithuania

The ways in which informatics is covered in K-12 education vary among European countries. In Finland and Sweden, informatics is not included in the core curriculum, whereas, for example, in Lithuania, all students are exposed to some informatics concepts starting in the fifth grade. Bebras is an annually arranged international informatics contest for K-12 level, resulting in a large collection of data about contestants and their results. In this paper, we analyse contest data from the Finnish, Swedish and Lithuanian 2013 con- tests, focusing on students' performance on tasks related to algorithmic thinking. Our findings suggest that despite coming from different educational systems, students perform rather similarly on the tasks. The same tasks are difficult and the thinking behind picking an incorrect answer seems rather similar throughout the countries. The analysis also points out that there is a lack of easy questions -- this needs to be fixed in order to not risk scaring students away.
