The purpose of this study was to investigate the effects of gender, science achievement, perceptions of science, and out-of-school experience on middle school students' science career aspiration. We conduced a survey on 181 middle school students and investigated whether there was a difference in perception of science and out-of-school experience according to science career aspiration, and derived the eight variables from survey items based on exploratory factor analysis. And we conducted a logistic regression analysis that explains the effects of eight derived variables, gender, and science achievement on science career aspiration. The result of analysis showed that only two factors such as 'interest and preference for science learning' and 'use of everyday tools' were significant to explain science career aspiration. It has thus been found that it is important to increase students' interest in and preferences for science learning and use of tools in everyday life in order to increase their science career aspiration.

In this study I investigate how native Korean listeners perceive English vowels /i/, /I/, and /$\epsilon$/. I extend Flege et al's (1997) study with synthesized /i/-/I/ and /I/-/$\epsilon$/ continua, and apply the results to Flege's (1995) Speech Learning Model (SLM). The statistical results show that native speakers of English rely more on spectral steps than on vowel duration when they identify the /i/-/I/ continuum, whereas native speakers of Korean rely more on vowel duration than on spectral steps when they identify the same continuum. In the case of the /I/-/$\epsilon$/ continuum, both groups rely on spectral steps when they identify the /$\epsilon$/, which supports the SLM; Koreans identified the /$\epsilon$/ categorically since Korean has the equivalent vowel. However, there was not statistical difference between Korean subjects with more English experience (KE) and those with less English experience in the identification of both continua. This contradicts the SLM, which posits that experienced L2 learners are better than inexperienced L2 learners in perception of L2 sounds. The exact nature of this should be further investigated in the SLM.

In the era of the Fourth Industrial Revolution, improving computational thinking to solve problems by smoothly operating and utilizing software. Therefore, the ministry of education has introduced systematic SW education into public education as a revised 2015 curriculum with the aim of raising computational thinking. In order for SW education to be systematically stabilized at the school site, the teaching ability of the teacher must be supported above all. For this purpose, the government is promoting 'SWEET' for improvement of the elementary pre-service teachers' SW education program. However, even if the policy is pursued, there is a tendency to take measures to improve the teaching and learning methods in the field later, and since the subject of change in education is the teacher, it is necessary to grasp the reco-gnition, experience of teachers. This study analyzed qualitatively perception and experience of elementary pre-service teachers about SW education and suggested design guidelines for pre-service teacher training such as providing various learning examples.

As the teacher-centered education is transformed into learning-centered education, the active knowledge construction of learner becomes important. Along with this change, project-based learning is receiving attention. However, there are many problems to apply the results of research to pre-service teachers because most of the previous studies have focused on elementary middle high school students. Therefore, this study examined the changes in perceptions of pre-service mathematics teachers while project-based learning progressed for one year. Pre-service mathematics teachers had less experience with project-based learning than group discussions, group activities. Also their perceptions was classified as five factors: 'Instructional effects', 'Application and participant of project-based learning', 'Achievement', 'Diffusion of project-based learning', 'Student motivation'. Pre-service mathematics teachers responded positive changes in perception that project-based learning could be motivated to students but they responded negative changes in perception that project-based learning could be distributed to school. They responded positive changes in perception that teachers can show their achievements by project-based learning but they responded negative change in perception that teachers would be fun to apply project-based learning. Also, they responded positive changes in perception that teachers and students were easy to apply or utilize project-based learning.

This study, for learners using online and offline tools, understood the structural relationship of user experience of smart learning app on continuous use intention through the technology acceptance model, and classified the learning type characteristics. In addition, based on the experience of using the smart learning app, we explored ways to improve the design of the user experience design for learning tools and contents. For this purpose, the usage perception of 84 middle and high school students of the developed smart learning learning app was investigated after using it for 2 months, and the data were analyzed using the PLS structural equation technique. The main results of this study are as follows. First, system and content user experience had a significant effect on perceived usability and perceived ease of use, and the effect on continued use intention through attitude was significant. Second, there was a significant difference in the effect of system user experience on perceived usefulness in multi-group comparative analysis and gender group. In the preferred learning group, it was the path from perceived ease of use and perceived usefulness to attitude and intention to continue using that showed a significant path difference. Third, as a result of classifying the most commonly used learning types by the multidimensional scale method, the types separated into low dimensions were found to be four types: offline sync type, online sync type, ubiquitous learning type, and self-direct learning type.

By developing and implementing a book curation education program that reflects the experiential economy theory, this study aims to verify the effect that experience perception of the program has on continuous participation intention and perceived value of the program. Teaching and learning activities of book curation education programs were organized so that practitioners can experience activities for 4 experience element, entertainment experience, educational experience, escapist experience, esthetic experience according to experience economic theory. This study surveyed 195 peoples who participated in the program to measure the effectiveness of the program. As a result of analysis, research hypothesis 1 (the perception of experiences in the book curation education program affects the perceived value of the program) revealed that aesthetic and entertainment experiences were significant, and research hypothesis 2 (the perception of experience in the book curation education program affects the intention to continue participating in the program) showed that all other factors except educational experiences were significant.

This study's purpose is to investigate elementary school teachers' perception on infographics learning materials. For this, this study made a questionnaire about infographics cognition or not, the need for development of infographics learning materials, science class applied infographics. And then, this study conducted a survey of 300 elementary school teachers. Through this process, this study had the results that most elementary school teachers had not some experience infographics and had never applied infographics during the class. On the other hand, elementary school teachers who had some experience said that they had used infographics in society subject and science subject. And they said that infographics was used in the development stage of class. In the need for development of infographics learning materials, this study had the results that elementary school teachers recognized the quantities of infographics which could apply in learning materials of elementary school inadequate. And elementary school teachers said that they needed infographics learning materials which could actually apply in class. Also, elementary school teachers said that the subject which could be most applied infographics learning materials was society subject and science subject. And they said that infographics learning materials was a good method which can be applied to third grade and fourth grade in elementary school. In science class applied infographics learning materials, elementary school teachers said that the best class stage to presenting infographics learning materials was full-scale lesson of each chapter in curriculum and they recognized that infographics learning materials must be used for understanding scientific concepts. Add to this, elementary school teachers recognized that the development of learning materials with the application of infographics learning materials must take precedence in order for education applied infographics learning materials to carry out successfully.

This study analyzes the perceptions of college students majoring in aviation services according to the field learning program conducted during their major studies in order to reflect the educational value and academic awareness of the experience of the experiential field learning program. A survey is conducted targeting college students who experience a field learning program conducted by the Aviation Service Department of J University, a four-year university in the Chungcheong region. ANOVA (one-way analysis of variance) is conducted to analyze differences in perceptions of field learning properties, learning satisfaction, academic self-efficacy, and intention to continue studying. Additionally, text mining is conducted using 'Voyant Tools' to analyze students' field trip logs regarding field trip learning program activities. I hope that the results will be used as evidence to build an efficient and systematic learning strategy for operating field learning programs.

Recently, there is an increasing number of universities in which SW education is operated as a liberal arts education regardless of major. In this paper, the survey is conducted to analysis the factors affecting the non-majors students' perception of the necessity of SW education through a case study of SW liberal arts by gender, college, and SW learning experience. As a result, men, students of social science college, and students with SW learning experience strongly agreed that SW education for non-majors is essential. 'SW education is very helpful in studying my major' was analyzed as a necessary condition of SW education for non-majors. Especially, the difficulty of SW learning did not affect the recognition of the necessity of non-majors SW education. If the SW liberal education is based on the SW technology that helps their major, it will be expected that the improved learning motivation due to majors-relevance will deepen a consensus on SW education.

The purposes of this study was to analyze qualitatively changes in students' experience and perceptions in relation to studying science using portfolios and any resultant effects on the portfolio itself. Five fourth-grade elementary students from one small city participated in this study. Data was collected through interviews as well as through student portfolios containing the science content matter of two units over two weeks. Observational diaries recorded by a teacher were also used to test the reliability of data collection. All interviews with students were transcribed to develop a suitable network to categorize students' responses. Students' portfolios were analyzed in order to reveal their essential characteristics in combination with their teacher's observational diaries. The results were as follows. First, student perceptions of their portfolios were categorized into three different levels; superficial, extended, and moderate perceptions. The changes in perception could also be divided into three levels; consistent-superficial, unstable, and a progressive-extended pattern. Second, the experience of students with their portfolio were investigated in terms of the following; successfully completing the elements of the portfolio, development of evidence, interaction with peers, teachers, and parents, and the standards of evaluation used for the portfolios. Third, the perceptions and experience of working on the portfolio by students had a number of direct effects on the way in which students actually created and developed their portfolios. Finally, students with positive attitudes towards their portfolios actively participated in the portfolio experience and finally understood what it meant completely. However, students with negative attitudes regarding portfolio based work, did not leave the experience with any heightened awareness of the utility or indeed, purpose of portfolio based work.
