The purpose of this study was to survey the students' career choice related to science. Important factors of career choice were identified through factor analysis. 'Perception of career related to science', 'preference for science learning' and 'participation in science-related activity' were three main factors of science-related career choice. Students' responses to the three main factors were compared according to their career choice, grade and gender using ANOVA. Regression analysis was adopted to find out the relative importance among the three main factors. The subjects were 947 grade 6, 9 and 11 students in Seoul. Numbers of boys and girls in each grade was almost same. The questionnaire was developed to know the factors of students' science-related career choice after preliminary research and literature survey. The ratio of science-related career choice was not high (26%). Students' responses to and the relative importance of the three main factors differed with the grade and gender. From the results, making students have preference for science and giving them more opportunities of science-related activity is more important than making them have positive perception of science-related career. It is required to make a material for science career education considering the differences of age and gender using this study results.

This study is the analysis of interview with science major student about the effect of science club experience on career decision. The special interview was planned and arranged to meet students as well as their teacher. Both of the student whose background had experience in the science club activity, field science education during their high school days are majoring in physics and biology. In Summary: 1) science teacher's guidance deeply impressed the student that they respect the teacher as a occupational role model. 2) they really enjoyed the hands-on activities joyful. 3) their experience lasted so long time to keep them to stay in science field. 4) they had an experience of speaking before peer science club students who had similar interest and talent. We found the above four factors were really influential to encourage the subject to major in science career.

The purposes of the study were to develop STEM instructional materials for teaching and learning mathematics and to investigate how the STEM based approach affects on students' learning of mathematics in cognitive and affective domain and career choice. STEM instructional materials were designed for learning of mathematical concepts in the contexts of science, technology, and engineering as well as real world. According to the results of the study, STEM instructional materials for teaching and learning mathematics were effective for improving students' problem solving ability and affective achievement such as self-regulation, self-efficacy, and value of mathematics. In addition, STEM program played a positive role in tempting students' career choice into science and engineering fields including mathematics.

This study investigated the Chinese national university entrance examination (Gaokao) in mathematics administered in 2009 and 2010 to draw out some implications on the College Scholastic Ability Test (CSAT) in mathematics of Korea. To evaluate the attainments of basic mathematical skills and multilateral abilities required for further studies in university, the Gaokao mathematics is set in two forms(Art/Science), based on the Chinese national mathematics curriculum. The types of items in the Gaokao mathematics are multiple-choice, single-answer, and write-out-answer. The mathematical abilities that the Gaokao mathematics evaluates are mathematical reasoning, operation, geometrical imagination, application, and creativity. As a result, some implications on the Korean CSAT are drawn out in terms of the level of difficulty, the types of items, the arrangements, and the scores of items.

We compared algorithmic problem solving and conceptual understanding of chemistry with three types (algorithmic, pictorial- and wordy-formatted conceptual) of problems. The familiarity, confidence, and preference to the three type of problems were also examined. The chemistry problem solving ability test was administered to 228 students from two top high schools in the province of Gyeonggi who were preparing the chemistry examination among the four optional subjects (biology, chemistry, earth science, physics) for enter university. After administrating the chemistry problem solving ability test, the degree of familiarity to some problems and the degree of confidence of their answers in a Likert scale were asked to the students. Besides, the students were asked to place preference to the type of problems in order. The students scored better on the algorithmic problems than on the conceptual problems (pictorial and wordy problems), and were also most familiar with the algorithmic problems. The students were more confident of their answers on both of types pictorial and algorithmic problems, and preferred pictorial problems rather than both of types algorithmic and wordy problems.

The development of hardware, popularization of 3D graphics software could get to easily use 3d graphics tool in the school. And learning difficulties of a shape section increased through more being enforced a shape section of an elementary school. Thus we try to improve learning effectiveness in a shape section using Sketech Up software. To do this, we analyzed existing studies, classified 3D graphics software, provided the selection criteria of vector graphics software. And we explained how to select 3D graphics software. We selected and reorganized the shape contents to use Sketch Up, which make and rotate 3D figures, understand aspects of a shape. And we inserted the content about piling 3D figures in the beginning state of the curriculum. we composed 10 periods and practiced our reorganized curriculum to the teaching and learning using Sketch Up. And we conducted before & after survey to check out t-verified. And we acquired meaningful results statistically. Thus applying Sketch Up to the shape learning can be analyzed effectively.

This study was intended to explore the changes in teaching methods when freedom to choose curriculum, instruction, and evaluation methods is allowed and when 'free semesters' are free from entrance examination for high school. For this question, we analyzed free semester education plans of eight sample schools and interviewed 33 teachers and students respectively. The results were as follows. Firstly, all schools planned to use teaching methods for meaningful learning, although they are limited to those exemplified in guidelines for free semester. Secondarily, teaching methods adopted for free semester were characterized as activities enhancing student participation. Thirdly, teaching methods such as career exploration, scientific experimentation, cooperative learning, flipped learning, interdisciplinary learning were used only a couple of times in a semester. Changes in teaching methods were referred to enhance students' interest, confidence, self-regulation, creativity, problem-solving and cooperative learning.

This study researched on job-esteem of the students who are majoring in aviation operation services. Examining the differences in feelings of job-esteem on one's university and grade level, firstly, the result among universities indicated that the difference in positive value and social reputation factors but there's no difference in negative treatment and relative profit factors. secondly, the result indicated that there is a difference in feelings of job-esteem based on one's grade level in positive value, social reputation, and negative treatment except relative profit factors. Also, the result of this study on how variables of population statistics and satisfaction on the college major and self-esteem as flight attendants affect subordinate factors of job-esteem showed only variables of satisfaction on college major affected positive value, social reputation, negative treatment, relative profit factors.

The most recent concept in anterior cruciate ligament reconstruction is an anatomical single bundle anterior cruciate ligament reconstruction. For an anatomical anterior cruciate ligament reconstruction, the tibial tunnel is made anterior than before, and the femoral tunnel is made in a lower and oblique direction compared to the classical method using the transtibial technique. The anteromedial portal technique, outside-in technique, and modified transtibial technique have been performed to produce femoral tunnels with anatomical positions. Each method has different advantages and disadvantages and is chosen based on the operator's preferences, experience, instruments, and implants.
