First year students Aeronautical Engineering had the opportunity to enter a five days program to enhance their mathematical skills. The program had 55 participants. Our research questions were: What are the effects of participation in the summer school program on math skills? Do participants experience more motivation and academic self-esteem after participation? Do dropout rates differ between participating and non-participating students? Do participants differ from non-participating students in motivation or academic self-esteem? We presented the results at the European First Year Experience in Cork, Ireland.
