Abstract

The object of this study is to determine the
conceptual understanding that prospective Science teachers have relating
"de Broglie: Matter waves" and to investigate the effect of the
instruction performed, on the conceptual understanding. This study was
performed at a state university located in the western part of Turkey, with the
Faculty of Education-Science Teaching students (2nd year / 48 individual) in
the academic year of 2010-2011. The study was planned as a single group
pretest-posttest design. A two-step question was used in the study, prior to
and after the instruction. Lessons were conducted using the 7E learning model
in the instruction process. When all these results are evaluated, it can be
said that the conceptual understanding of the prospective teachers regarding
"de Broglie; matter waves" has been taken place. In general, when all
the sections are examined, it has been observed that the prospective teachers
have more alternative concepts prior to the instruction and more scientific
concepts after the instruction.  In this
process, besides instruction, the prospective teachers have not taken any place
in a different application regarding the basic concepts of quantum physics.
Therefore, it has been determined that the 7E learning model used in the
research and the activities included in the 7E learning model are effective in
conceptual understanding.
