The purpose of this study is to verify the effects of collaborative reflections using SNS(Social Network Services)
on college student’ learning motivation, problem solving competency, and academic achievement in Creative Problem
Solving activities. 51 college students who were taking a course ‘Instructional Methods and Educational Technology’ in
a university in Seoul were participated for this research. These students were allocated two groups, one was an
experimental group of 26 students, the other was a control group of 25 students. After mid-term examination, all
students of these two group performed Creative Problem Solving activities in the course for six weeks, but only
experimental group’s students did collaborative reflection by using facebook, a kind of SNS. Pre- and post-test on
motivation and problem solving competency were conducted for both experimental and control group students before
and after creative problem solving activities respectively. To verify the effects on academic achievement, final exam
result which was designed to measure subject knowledge and student-based creative solving skills and creative problem
solving task report score was used. Analysis of covariance(ANCOVA) in which pre-test scores on motivation and
problem solving competency respectively were covariates and independent sample t-test with final exam scores and
creative problem solving task report scores of participants students were used for statistical analysis. In addition, the
qualitative analysis of the collaborative reflection activities on facebook is performed to strengthen the statistical
analysis results on the learning motivation, problem solving competency, and academic achievement. As a result,
collaborative reflections using SNS don’t affect on motivation, but have an effect significantly on problem solving
competency and academic achievement(p<.05). This research shows that SNS can provide college course with an
effective environment of collaborative reflection, which is to improve college students’ creative problem solving
competency.
