An Overview on the Mental Models About the Structure of Atom for High School and University Students
Öz
Many students have considered the structure of an
atom as a difficult topic since it includes abstract concepts. Therefore,
students construct mental models in their mind in order to grasp the structure
of atoms and these mental models interfere with their learning. This study aims
to explore mental models of the high school students and university students
related to the atom by examining the studies in the literature in order to
portray how students perceive the structure of atoms. In this context, the
studies related to the mental models were documented and analyzed by using content
analysis. In order to categorize the studies with respect to some certain
characteristics, the main themes were formed by the researchers and the
analyses were conducted based on these themes. Examining the mental models of
the students, it was observed that they drew a solid sphere or some electrons
orbiting around the nucleus. Moreover, electron cloud model were the least
drawn model even though it was included within the educational programs.
Besides, some misconceptions were determined within the studies by examining
the mental models of the students. Most
of the researchers conducting these studies recommended that modeling should be
included more in the instructions of the teachers. Moreover, they suggested
that current educational programs should be rearranged in order to eliminate
the possible misconceptions pertinent to the structure of an atom.
