Διερεύνηση της ικανότητας των φοιτητών Χημείας στον νοητικό χειρισμό (περιστροφή και κατοπτρισμός) 2D συμβολικών μοριακών αναπαραστάσεων.
Translated title:
Investigation of the ability of Chemistry students to mental manipulation (rotation and mirroring) 2D symbolic molecular representations
Summary:
In Chemical education, comprehension, understanding and treatment of molecular
representations are important gnostic procedures. Many researches have shown a
positive correlation between spatial ability of those being tutored and their
progress in Chemistry. Visual spatial ability is a basic element of spatial
ability and includes visualization, transfer and treatment of non-verbal
information, such as symbols, images, objects
and their parts in two-dimensional and three-dimensional space. The present
thesis examines the general visual spatial ability of Chemistry students as
well as their ability to visualize and treat mentally (rotation and reflection)
molecular structures, through the observation of their two-dimensional symbolic
representations. The research was carried out with the use of the electronic
edition of Purdue Spatial Visualisation Test of Rotation PSVT:R of Purdue
University, as well as with the use of two original tests on visualizing mental
rotations and reflections of two-dimensional symbolic molecular
representations. The applications were designed and elaborated for this reason
and were implemented in 37 first year students of the Department of Chemistry
of Aristotle University. The findings of the research came up after analyzing
their progress, false answers and estimated time of reply of the participant
students in the three visualizing tests.
