Abstract
The paper is based on collecting evidence of the Establish project impact on students. For the purpose two questionnaires based on the existing tools have been used.
Questionnaire 1 is a part of Intrinsic Motivation Inventory (IMI) based on the Self-determination theory. It is aimed at assessing students' interests, their perceived choice and usefulness of implemented learning units and should be answered after each learning unit/several IBSE activities.
Several items of CLES questionnaire are included there as well. Questionnaire 2 assesses the impact on students' attitudes towards science and technology and on their knowledge about nature of building up science knowledge.
Both questionnaires exist in the lower and upper secondary school versions. The paper presents selected data and results which were obtained by addressing the Questionnaire 1, so that the focus is on getting students' feedback about their intrinsic motivation.
