Özet:

 


Students come across with the notion of atom almost
every year during their education life. Higher conceptual understandings of
atomic theories among science teachers is of crucial importance in their
understanding of physics and chemistry courses. In this sense, the purpose of
the present study is to investigate which of the atomic theories science
teachers often confuse and to discuss the possible reasons behind the confusion
of one theory with the other. This study used the phenomenology method of
qualitative research. Participants of the study were comprised of 55 first and
second year university students attending the Department of Science Teaching
during the 2015-2016 academic year. In order to discover the most confusing
atomic theories and the reasons of this confusion, students were asked to write
down the atomic theories that they often confuse with one another and the
reasons why they do so. Using content analysis, two independent coders analyzed
the collected data. The result of the analyses revealed that students mostly
got confused between Bohr’s Atomic Theory and Modern Atomic Theory. It was also
found that the underlying reasons of this confusion were that “In both theory,
the protons and neutrons are found together at the center of the atom (the
nucleus) surrounded by electrons spinning around it” and “students cannot
differentiate between the concepts of layer, orbit and shell”, and some
recommendations were offered concerning the instruction of these subjects.
