The purpose of this research is to examine the effects of the flipped learning-based
historical persons leaning on the historical knowledge and the ego-identity of the
students with intellectual disabilities. To solve these research questions, 30 special
class high school students were selected and they were divided into the experimental
group consisting of 15 students and the control group consisting of 15 students, and
the flipped learning-based historical persons learning was conducted on the
experimental group for a total of 20 sessions and on the control group, the traditional
teaching of the historical persons learning was conducted, and the differences in
effects in the pre- and post-test results of the historical knowledge test, which is
teachers-made test, and the Korean ego-identity test developed by Park Ah-cheong
(2003) were verified through ANCOVA. Results of this study are as follows: flipped
learning-based historical persons learning showed significant differences between the
control groups in the questions of choice of persons in the historical knowledge test
of the students with intellectual disabilities, and it was found that there were
significant differences between the control groups in the two domains of the
ego-identity test: identity and goal directedness, showing that there were significant
effects in enhancing historical knowledge. In the case of the traditional teaching of
the historical persons learning, the average score of the post-test was higher than the
average score of the pre-test in the historical knowledge test and the ego-identity
test but there were no statistically significant differences. Accordingly, it is considered
that the flipped learning-based historical persons learning is the effective teaching
strategy to enhance the historical knowledge and ego-identity of the high school
students with intellectual disabilities.
