The participants consisted of sixteen graduate students tested in their understanding for scientific concepts before and after instructions. Students journals show that it is important to: address and challenge students theory regarding Newtonian laws; to form coherent mental macroscopic dynamic imaginative picture regarding electricity, magnetisms, gravity, light, sound, heat, pressure and the particulate nature of matter; to elect the revolutionary type of knowledge and present them in linear hierarchical way regarding biological concepts.
