The National Center for Learning and Teaching in Nanoscale Science and Engineering was established to conduct research on how to effectively introduce emergent sciences into K-16 classrooms, using nanoscale science and engineering (NSE) as an example. One of the NCLT's main goals is to develop an approach to map out the knowledge domains (constructs)(More)
This study explores students understanding of key concepts in nanoscience with the intention of identifying a potential threshold concept in the field through the analysis of student concept maps and explanatory interviews. The analysis of students' maps indicates conceptual development and learning difficulties in learning size–dependent property change at(More)
