Knowledge of Atomic Structure and Visualization: Research Results from Questionnaire with First-year Chemistry Students

Abstract

Research assessed students' knowledge regarding basic general chemistry and physics concepts, particularly atomic structure knowledge and atom visualization models. Results showed predominantly descriptive, simplified student understanding based on Rutherford or Bohr models rather than current scientific models. Only 5% demonstrated expected scientific literacy after two semesters. Alternative learning sequences are recommended to develop abstract thinking necessary for complete scientific literacy.
