This study seeks to examine the effect on the 35 pre-service special education
teaching efficacy by their development and demonstration of Practical Arts of Special
Education Curriculum through Lesson Study(LS). The results obtained through the
integrated research (qualitative, quantitative) and the action research methods based
on the data generated in the course of the spiral circulation process of collaborative
lesson planning, micro teaching, the findings of the results, and the analytical
reflection and revision of the pre-service special education teachers are as follows.
First, this is the result of the qualitative analysis. As they go through the
three-stage spiral circulation process of LS, they have improved their collaborative
lesson research capacity among their fellows and their capacity of classroom
observation and evaluation, and have had their confidence in lesson. Secondly,
according to the results of the quantitative analysis, their teaching efficacy beliefs and
completion of teaching plan of the 1st class were found to be more improved in the
observation paper evaluation of all the 9 teams than those of 2nd class. Thirdly, the
result of applying the collaborative lesson study (LS) model to the action research for
a school term shows that the cooperative expertise of the pre-service special
education teachers is improved by and large, but a problem with this model is that
the ultimate goal of this model focuses too much on the teaching techniques training
of teachers rather than the improvement of learning behaviors and learning
opportunities of the students in need of special education. This is expected to be a
significant implication on the follow-up studies in the future.
