Segedinac, M. T.; Horvat, S.; Rodic, D. D.; Roncevic, T. N.; Savic, G. – Chemistry Education Research and Practice, 2018
This paper proposes a novel application of knowledge space theory for identifying discrepancies between the knowledge structure that experts expect students to have and the real knowledge structure that students demonstrate on tests. The proposed approach combines two methods of constructing knowledge spaces. The expected knowledge space is…
