Submicro Level in Chemistry Education: Atoms, Ions and Moleculesto Understand Acid-base and Redox Reactions | Chapter 11 | Current Research and Development in Chemistry Vol.1
From
experiences all over the world we know that formulae and chemical equations are
memorized very often or are equalized by counting the number of „atoms on the
left and right side of the equation“. Looking to our Chemical triangle (Fig. 1)
lecturers and students are jumping from the Macro level just to the Symbolic
level. If we would go first from Macro level to Submicro level and explain
chemical reactions with involved atoms, ions and molecules, learners would
understand chemistry more successfully. With a special questionnaire we are
investigating the ability of university students and chemistry teachers in
Indonesia, Tanzania and Germany to interpret given chemical equations with
involved particles. We found a lot of misconceptions and proposed how to
challenge them.
