Students´ Knowledge about Nanotechnology and the Importance to Introduce Nanotechnology into Chemistry Lessons

E Daoutsali, H Barke, O P Yadav

Abstract


The primary objective of this study was to find out what students already know about nanotechnology in order to design a context based module with a nanotechnology background. Therefore a questionnaire was distributed to 116 German students in grade 11. Questions referred to the first thought of the students´ mind when they hear the word nanotechnology, to the size of a nanometer, to if something can be seen at the nanometer scale with the unaided eye, to their self-assessment concerning nanotechnology and to the surface-to-volume ratio of nanoparticles. The findings of the students´ answers were informative and allowed us to design a module in the future that can lead students at school level to understanding nanotechnology.
