STUDENTS' VISUOSPATIAL ABILITIES AND COMPREHENSION - LEARNING OF CONCEPTS RELATED TO MOLECULAR STRUCTURE. DESIGN, DEVELOPMENT AND EVALUATION OF EDUCATIONAL MOLECULAR VISUALIZATION AND ENHANCED REALITY SOFTWARE FOR SECONDARY AND TERTIARY EDUCATION

Abstract: 

Chemists have developed a rich symbolic language to describe spatial relations of aperceptual particles of microscopic world (atoms, molecules) for interpreting, investigating and communicating chemical concepts and phenomena. The only perceivable features of microscopic world are those embedded in the symbolic chemical representations like molecular models, chemical structures, formulas, equations and symbols.

Research data tentatively reveal that understanding chemistry and performing in chemistry learning tasks using these representations are based upon the visuospatial (VS) ability of the learners, that is their capacity to perform spatial cognitive operations, such us recognition of graphic conventions and depth cues, manipulation of spatial information embedded in the representations, and mentally tracking of constraints based on concepts.

The aim of the proposed research, development and innovation project is: 

  • The examination of the hypotheses that individual differences in VS ability predict learning in chemistry and that conceptual errors in chemistry arise from difficulties in comprehending, translating and transforming visual representations.
  • The development of interactive 3D molecular visualization and augmented reality educational software supporting VS thinking and learning in a chemistry context related to molecules' structure and dynamics.
  • The integration of these technologies into models of instruction and application of the models in secondary and tertiary education.
  • The evaluation of the instructional models' impact on students VS thinking, conceptual understanding, reasoning ability and performance in learning chemistry.
