Online activity practices based on common knowledge constructing model: Example of radioactivity topic
Özet
The aim of this study was to examine the effect of the
Common Knowledge Construction Model (CKCM) on the
conceptual understanding of science teacher students about
Radioactivity. CKCM was used. In order for the students to
adapt the radioactivity subject, which they see as difficult and
abstract, to daily life by knowledge structuring. This study was
carried out with 48 students studying in the second year of
science education at a public university in the western region.
The research employed pretest-posttest control group random
design. The Radioactivity Concept Test (RCT) with 2 phases
consisting 23 multiple- choice items were used as data
collection tools in the research. After the tests were applied as
a pilot study to 124 students, it was used with the participants
of the study after the necessary validity and reliability studies
were carried out. The KR20 reliability coefficient obtained
from the sample data was calculated as 0.74. In the study,
experimental and control groups were formed by random
assignment. While the traditional lecture method was applied
to the control group, the CKCM was applied to the
experimental group. When the concept test data were analyzed
with the SPSS 24 package program, it was determined that the
experimental group were more successful than the control
group. determined that the increase in correct answers in the
post-test of the experimental group was higher than that of the
control group.
