The purpose of this study is to investigate how engineering design-based STEM research experience affects gifted students' creative engineering problem-solving propensity and attitude toward engineering. The students' creative engineering problem-solving propensity and attitude toward engineering were measured before and after the STEM research experience. The pre-/post-tests results were analyzed by paired t-test with the significance level of p <.05. The conclusions of the study are as follows: First, the engineering design based STEM research experience had a positive effect on the students' creative engineering problem-solving propensity. Over all, the average score of the creative engineering problem-solving propensity increased significantly (p <.05) after the STEM research experience. Second, the average score of gifted-students' attitude toward engineering had increased significantly after the integrated STEM research activities (p <.05). In addition, we analyzed the difference between pre-post results of both instruments based on the gifted students' desired career paths (natural science and engineering) and gender. The result shows that the students' career paths or gender did not affect the results in most of the sub-categories in both instruments. However, the STEM research experience had more positive effect on the female students than male students in term of their 'engineering design ability', which is one of the sub-categories of the creative engineering problem-solving propensity instrument.

The study in this paper considers how elementary school students' interest in mathematics and STEAM literacy could be promoted by conjoining the learning of mathematics with the learning of drone topics. Survey instrument was developed to measure student attitudes toward mathematics and science subjects and to evaluate student beliefs on learning mathematics embedded in science topics. Data were collected from elementary school students by administering pre- and post-tests: students were intervened with examples of math problems embedded in certain science contexts. The findings indicate that elementary school students' experience of solving mathematics problems embedded in science contexts positively affects the promotion of their attitudes toward, beliefs on science subjects and science and engineering career path selection. We hope that the mathematics program using the drone will be used in the classroom for STEAM.

The purpose of the study is to examine prospective librarians' library practicum experiences by using Giorgi's descriptive phenomenological method. To achieve the purpose of the study, the study conducted in-depth interviews with the participants of the library practicum in the department of library and information science at the A university. Following Giorgi's four ways of phenomenological description, the study analyzed the collected data from in-depth interviews with the participants. Prospective librarians' library practicum experiences were able to analyze as five significant themes and seventeen sub-categories of the themes. The five main themes are as followings: 'formulating perception of libraries and librarians', 'formulating career design through self-development and challenges', 'growth and challenges in preparing the library practicum', 'growth and challenges in the middle of library practicum' and 'experiences after the library practicum and the evaluation.' On the basis of the findings, the study suggested alternative programs of library practicum and the directions for performing the programs effectively and efficiently.

This study examined the structural relationships among parental attitudes and expectations toward mathematics, mathematics motivation and achievement of their child in PISA 2012 of South Korea. Data were analyzed using structural equation modeling(SEM) analysis. The results were as follows: First, parental attitudes toward mathematics had positive effects on parent academic and professional expectations in mathematics. Second, parental expectations also had positive effects on intrinsic motivation, instrumental motivation and math achievement for their child. Third, instrumental motivation had strongest effects on math achievement. The next factors which had effects on math achievement were intrinsic motivation and parental expectations in order. This results shows that the parental awareness of the usefulness and necessity of mathematics will help to increase the interest and value toward mathematics, math achievement and interest of math related carriers of their child.

Students' perception of science-related career strongly influences the formation of career motivation in science. Especially, the high level of science gifted students' positive perceptions plays an important role in allowing them to continue to study science. This study compared perceptions of science-related career between general and gifted middle school students using semantic network analysis. To ensure this end, we first structuralize semantic networks of science-related careers that students perceived. Then, we identified the characters of networks that two different student groups showed based on the structure matrix indices of semantic network analysis. The findings illustrated that the number of science-related careers shown in science gifted students' answer is more than in general students' answer. In addition, the science gifted students perceived more diverse science-related careers than general students. Second, scientific career such as natural scientists and professors were shown in the core of science gifted students' perception network whereas non-research oriented careers such as science teachers and doctors were shown in the core of general students' perception network. In this study, we identified the science gifted students' perceptions of science-related career was significantly different from the general students'. The findings of current study can be used for the science teachers to advise science gifted students on science-related careers.

This study was undertaken for identifying ways to positively resolve problems associated with perceived overqualification from the perspective of job crafting, which is highlighted as a social issue in the labor market. We hypothesized the mediating role of job crafting in order to uncover the questions regarding when and how perceived overqualification associates with an employee's organizational commitment. Autoregressive cross-lagged models were applied to the longitudinal data gathered from 263 full-time employees across 3 waves over 9 months. Our results demonstrate positive and significant cross-lagged effect of perceived overqualification on job crafting and organizational commitment. However, the cross-lagged effect of job crafting on perceived overqualification was found to be insignificant, but was significant for organizational commitment. There were no other indications of reverse causation effects. Our data indicates that job crafting longitudinally mediates the relation between perceived overqualification and organizational commitment. These findings offer a meaningful implication that employees who perceive themselves to be overqualified should be given an opportunity to craft their own jobs.

This study analyzed some of the discrepancies in quantitative and qualitative data focusing on cognitive and affective achievement in science education. Academic and affective achievement score of 308 high school students were collected as quantitative data, and 33 students were interviewed for qualitative data. We examined the causes and types of discrepancies in terms of testing tools. As a result from quantitative data, there were a large number of students with a big difference between subjects in cognitive achievement, and constructs in affective achievement. More than 20% of the students did not match tendency between achievements in two areas. Through interviews, some examples such as intentional control of science learning for future study and careers, different responses by differences in perception between school science and science, appeared. A comparison of quantitative data by testing tool between qualitative ones and interviews showed conflicting result, where most students evaluated themselves differently from their own quantitative data. That is due to the students' interaction with the testing tools. Two types of discrepancy related to testing tool are found. One is 'the concept difference between the item developer and students,' the other is 'the difference between students' exposed response and their real mindset.' These are related to the ambiguity of the terms used in the tool and response bias due to various causes. Based on this study, an effort is required to elaborate the testing item that matches students' actual perception and to apply students' science learning experience to testing items.

The purpose of this study was to investigate teachers' perception about 'Science Field Trip(SFT) to Korean historical sites'. Ninety-seven teachers were asked to reply the questionnaire about SFT to Korean historical sites. This questionnaire was divided into three parts: educational value, teaching method, and difficulty of management. Firstly, teachers indicated that SFT to Korean historical sites had much educational value in that it could give students chances to understand Korean culture, to acquire investigative process skills, to experience divergent investigation and cooperative learning, to raise integrated thinking skill concerning science and other subjects, and to learn contents related with science curriculum. It also had advantages of caring for students out of school and giving the information for future occupation. Secondly, teachers suggested the desirable teaching method: teachers' explanation about SFT to Korean historical sites with worksheets before it, students' group work during it, and the presentation and discussion after it. Finally, the most frequent answer in the difficulty of management was the lack of teaching materialsfor SFT to Korean historical sites.

In this study, we analyzed the learning elements and achievement standards, and explored the appropriateness and hierarchy of content were analyzed related to the nine types of traditional astronomical instruments presented in the traditional science unit of the History of Science course to improve the problematic situation in which students show low selection rates for the History of Science, one of the elective courses in high school science. Based on the results of this analysis, we suggested ways to utilize each astronomical instrument for teaching and learning in science curriculum with different grade bands. Using the results of this study as a starting point, if a follow-up study that develops specific achievement standards or inquiry activities related to traditional astronomical instruments can be conducted, students' awareness of Korean traditional science culture can be improved, and furthermore it is expected to increase the student's selection rate for the History of Science course.
