This study aims to investigate how flipped learning-based socioscientific issue instruction (FL-SSI instruction) affected middle school students' key competencies and character development. Traditional classrooms are constrained in terms of time and resources for exploring the issues and making decision on SSI. To address these concerns, we designed and implemented an SSI instruction adopting flipped learning. Seventy-three 8th graders participated in an SSI program on four topics for over 12 class periods. Two questionnaires were used as a main data source to measure students' key competencies and character development before and after the SSI instruction. In addition, student responses and shared experience from focus group interviews after the instruction were collected and analyzed. The results indicate that the students significantly improved their key competencies and experienced character development after the SSI instruction. The students presented statistically significant improvement in the key competencies (i.e., collaboration, information and technology, critical thinking and problem-solving, and communication skills) and in two out of three factors in character and values as global citizens (social and moral compassion, and socio-scientific accountability). Interview data supports the quantitative results indicating that SSI instruction with a flipped learning strategy provided students in-depth and rich learning opportunities. The students responded that watching web-based videos prior to class enabled them to deeply understand the issue and actively engage in discussion and debate once class began. Furthermore, the resulting gains in available class time deriving from a flipped learning approach allowed the students to examine the issue from diverse perspectives.

The purpose of this study was to investigate the effect that completing long-term on-site training with varying grades of success had on the job satisfaction of former university students after obtaining employment. Although the grades themselves achieved during long-term on-site training did not directly affect job satisfaction, positive effects on job satisfaction were shown due to the mediating effects of job match and organizational commitment. The results of this study are as follows: First, it was found that employees who participated in long-term on-site training showed different results in belonging and attachment to their organizations according to their achievement. The higher the grades during long-term on-site training, the higher the degree of reported job match and organizational commitment, suggesting a positive correlation with job satisfaction. Therefore, long-term on-site training should not be operated as simply a program for temporary experiential learning, but instead should be optimized by companies and schools to motivate their students to achieve high grades for the purpose of their future job satisfaction.

The purposes of this study are to develop cyber home study program on consumer life for youth in middle school students and to compare the learning effect of this program with that of teacher's off-line lecture in class. The contents of the middle school Home Economics. Technology textbooks was analyzed. Based on this analysis 4 cyber home study lesson plans on youth's consumer life were developed. The topics of lesson plan were as 'youth and consumer behavior', 'utilizing consumer information'. 'effective consumer choice', 'resolving consumer problems'. The cyber home study were composed of 5 steps which were 'guiding' $\rightarrow$ 'learning activities' $\rightarrow$ 'evaluation' $\rightarrow$ 'further study' $\rightarrow$ 'summery'. The second grade middle school students as an experimental group participated in cyber home study through on-line class. The control group of students who had same condition with the experimental group were taught by home economics teacher using traditional instructional methods in off-line class. After the experiment, the changes in consumer's attitudes and knowledge of both groups were analyzed using Analysis of Covariance. The significant improvements of consumer's attitudes and knowledge were found in both the experimental and control groups of students. However, the consumer's attitudes and knowledge of the students who were taught by the teacher in off-line class improved more than those of the students who studied using cyber home study program in on-line class. Thus, the following conclusion is made that the cyber home study could be one of the useful learning methods to aid traditional off-line teaching in class.

This study conducted an overall recognition analysis and demand survey of parent education programs in order to explore ways to promote parent education. Based on previous research, the questionnaire was developed including five factors and 23 items : (1) operating a center to support parent education, (2) perception on parent education programs, (3) developing a parent education program, (4) utilizing space, and (5) program operation and evaluation. A survey was administered on the parents of second and fourth graders at A elementary school in Chungju. The result showed that parents are positive about the operation of the center, which can provide professional support for parent education programs. There was also a great demand to strengthen the educational content of parents' roles. This study is meaningful in providing basic data for developing parent education programs based on the perception and demand analysis of existing parent education. Furthermore, the need for performance analysis and feedback was presented in future research directions after the actual development and operation of parent education programs that reflected the demand of parents.

This study aims to develop biology teachers' education program based on argumentation activity about core concepts of evolution and to analyze the characteristics of core concepts of evolution learned during the program. The eight core concepts of evolution in this study were variation, heritability of variation, competition, natural selection, adaptation, differential reproductive rate of individuals, changes in genetic pool within a population, and macroevolution. The performances of teachers participating in the program were compared before and after argumentation activities; consisting of seven sessions on the eight core concepts of evolution. The process of the program was specially designed by learning cycle model for teacher education, consisting of seven phases: identification of the task, production of a tentative argument, small group's written argument, share arguments with the other groups, reflective discussion, final written argument, and organization by an instructor. Participants in the study were two pre-service biology teachers and four in-service biology teachers. The results suggest that biology teachers reduced the teleological explanation for biological evolution and improve its adequacy after the intervention. Teachers lacked the opportunity to discuss variation, heritability of variation, competition, and macroevolution because science textbooks lack information on the concepts of biological evolution. The results of this study suggest that because the argumentation program developed for teachers helps to improve understanding the concepts of evolution and to reduce inadequate conceptions in biology, teacher education programs using argumentation activity and eight core concepts of evolution will play a role for efficient evolution education for biology teachers.

This study aims to make a comparison of educational effectiveness between instructor-centered learning and video self-instruction(VSI) about automatic external defibrillator(AED) for high school girls in order to help select an effective teaching method concerning AED. A total of 59 high school girls (29 for the experimental group, 30 for the control group) in J Province participated in this study from July 7 to 14, 2010. The analysis was carried out by using an SPSS WIN 12.0 Version program. After the AED instruction, the knowledge increased more in the experimental group (1.72) than that in the control group (1.60); self-confidence increased more in the experimental group (1.58) than that in the control group (1.46); and accuracy of technical performance increased more in the control group (5.46) than that in the experimental group (4.20). The experimental group (5.68) was more satisfied with AED instruction than the control group (4.95). Since video self-instruction proved to be more educationally effective than instructor-centered learning in most areas, it is necessary to apply video self-instruction to AED instruction in the future. However, further researches are necessary to see if video self-instruction is effective.
