This research was conducted to develop an assessment measure of attitude toward engineering. Based upon related document research and case studies, we came up with operational definition and category of attitude toward engineering as well as questionnaires to assess. After consulting with specialists and studying on relevant documents, we changed some of the 60 questions developed in the first phase or added new ones. One hundred and nine students who major in engineering were questioned by the 40 questions selected in the second phase. Using SPSS 14.0K statistics program, various techniques were used including factor analysis, validity analysis and correlation analysis. And the level of significance of statistical verification was 0.05. The result is as follows: Based on fundamental aspect of the attitude, this research focused on 3 different variables: cognitive variable such as 'attitude toward engineering value', affective available such as 'general attitude toward engineering and attitude toward engineering study', Behavior available such as 'participation in engineering activity'. Therefore, as a subcategory, attitude toward engineering value is classified into value as study and job, social value and personal value, general attitude toward engineering and attitude toward engineering study are divided into self-concept, self-efficacy, awareness, interest and cooperation. Also, participation in engineering activity is classified into attitude toward engineering study. After applying this measurement to the field, we integrated self-concept into self-efficacy, omitting one independent factor in the question. Finally, through Verimax, we developed 'Instrument of Assessment the Attitude toward Engineering(IAAE)' which consists of 3 variables, 9 subcategories and 39 questions.

This study investigates the level of the construction student's familiarity and interest in sustainability, their attitude toward sustainability, and the factors for bringing student's attitude toward sustainability. To accomplish the main objectives, this study employes a survey instrument created and developed by the authors. This is a descriptive and correlation study using responses from construction students at the Building Construction department at Virginia Polytechnic Institute and State University in Virginia. The results of descriptive statistics and multiple regression using SPSS version 16 present the following findings. Construction students perceive that they have a relatively high level of familiarity with sustainable construction and sustainability. Secondly, student's attitude toward sustainability is changed based on several factors such as sustainable construction courses, a professor who is interested in sustainability, their interest in the construction industry, university initiative, and the level of sustainability for student's learning facilities. Finally, the construction student's attitude toward sustainability can be improved by offering sustainable construction courses in construction programs, having professors who teach and research sustainability, and adopting sustainable initiatives at the university level such as campus recycling and various sustainable programs.

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 purpose of this study is to investigate engineering students' attitude toward convergence and relevance with engineering education accreditation, gender, and academic year and attitude toward convergence. To be specific, fist, we examined whether the instrument for measuring attitudes toward convergence were reliable and valid for engineering students. Second, we compared levels of attitudes toward convergence in terms of engineering education accreditation, gender and academic year. Third, latent classes, which were distinguished in terms of attitudes toward convergence, were identified. Participants were 2076 engineering students. By using factor analysis and Rasch analysis, validity and reliability of instrument measuring attitudes toward convergence were confirmed. The differences in attitude toward convergence in terms of engineering education accreditation experience, gender, and academic year were examined by independent t-test and ANOVA. There were significant differences in attitude towards convergence in terms of engineering education accreditation, gender, and academic year. Students who experience engineering education accreditation program and male and high academic year have higher levels of attitude toward convergence than others. Lastly latent class analysis (LCA) was conducted to identify subgroups underlying engineering students in terms of attitude toward convergence and five latent classes were identified. In addition, the chi-square results showed that there were significant relationships between identified latent classes and engineering education accreditation, gender, and academic year. Based on these results, engineering education considering students' characteristics and diversity in attitude toward convergence were discussed.

This study was designed to identify the Attitude toward Engineering and Teacher Efficacy of pre-service teachers of engineering department, evaluate the validity of the difference and inquire into correlation between the Attitude toward Engineering and Teacher Efficacy. The study results are as follows. First, the Attitude toward Engineering of pre-service teachers of engineering department turned out to be 2.94, which is below average(3.00), and a bit lower figure than that of Teacher Efficacy(M=3.34). Second, there was no significant difference between the Attitude toward Engineering and Teacher Efficacy in a gender factor. In case of a major factor and grade variables, there was significant difference between Attitude toward Engineering and teaching efficacy of Teacher Efficacy. Third, as a result of analysis on the correlation between Attitude toward Engineering and Teacher Efficacy, it turned out that there was significant difference between in sub-area a few, which leads to conclusion that the attitude toward engineering and Teacher Efficacy will be gradually improved if educational institutes training pre-service teachers of engineering department operate teacher education courses considering major characteristics and learners' levels and give successful guidance to pre-service teachers. In addition, since the gender factor didn't make any significant difference between the attitude toward engineering and Teacher Efficacy, there is no need to develop and operate separate educational programs only for female or male pre-service teachers.

This study aimed to develop an engineering design-based science education program for high school students and to investigate its effects on students' science-related attitudes and engineering design abilities. "Creating healthy shoes for maintaining proper posture program" was developed as an activity to come up with creative solutions using the methodology of an engineering design process to solve problems in daily life. The creating healthy shoes for maintaining proper posture program consisted of the following five stages: "defining the problem," "ingathering information related to the problem," "generating the solution," "implementing the best solution," and "evaluating the solution & reflecting." As a result of applying this engineering design-based science education program, it improved the high school students' science-related attitudes and engineering design abilities. Therefore, the program developed in this study has a positive effect on enhancing high school students' science-related attitudes and engineering design abilities. These findings imply that the continuous operation and expansion of activities incorporating an engineering design process in science education are necessary as a teaching and learning strategy for cultivating future science talents.

일반적으로 지진해일은 지진, 화산에 의한 융기 또는 침강에 따른 급작스러운 해저지각 운동에 의해 발생하며, 이에 따른 수위변동과 유체운동을 일컫는다. 그 밖에 해안/해저 산사태, 운석 낙하, 빙하 붕괴와 같이 암석, 토사, 얼음, 운석이 바다, 호수의 수면과 충돌하여 해일이 발생하기도 한다. 이 산사태 해일의 피해사례는 많지 않지만, 대부분 인명피해를 동반한다. 이에 과거부터 수리모형실험을 통해 산사태로 생성된 해일의 전파과정을 조사하는 연구들이 수행되었다. 최근에는 컴퓨터 성능향상과 다양한 수치모델이 개발됨에 따라 수치해석이 많이 수행되고 있다. 그러나 산사태 해일의 생성을 직접 모의하기 위해서는 유체-구조 상호작용(FSI; fluid-structure interaction)을 고려할 수 있는 전산유체역학(CFD; computational fluid dynamics)해석이 요구되는 관계로 활발한 연구가 진행되지 않고 있다. 본 연구에서는 FSI에 기초하여 충돌모의에 특화된 LS-DYNA를 이용하여 산사태 해일의 생성, 전파 그리고 직립벽(댐)에서의 처오름 및 파압 등을 검토한다. 그리고 낙하물의 형상, 낙하 높이에 따라 생성된 해일이 댐에 미치는 영향을 분석한다. 또한, 이용하는 LS-DYNA 해석의 타당성 및 유효성을 확인하기 위하여 기존 수리모형실험에서 생성된 산사태 지진해일과 비교·검증한다. 수치해석 결과, 동일한 체적의 낙하물에서는 폭이 좁을수록 최대파고가 낙하물에 근접해 생성되었고, 폭이 넓을수록 파장이 길어지는 것을 확인할 수 있었다. 낙하물의 낙하높이가 높을수록 산사태 지진해일의 파고가 크게 생성되었다. 낙하물로부터 600m 지점에서 설치한 댐에서의 산사태 지진해일의 처오름은 파고 및 파장이 클수록 증가하였다. 산사태 지진해일의 파압 역시 처오름에 상응하게 나타났다. 그러므로 호소에서 산사태 해일이 발생한다면, 댐 및 제방의 안정성에 영향을 미칠 수 있을 것으로 판단된다.

The purpose of this study was to investigate the effects of engineering design-based ocean cleanup classes on STEAM attitudes and creative engineering problem-solving dispositions. Furthermore, during this process, we tried to determine interesting points that students encountered in engineering design-based classes. For this study, a science class with six lessons based on engineering design was developed and reviewed by a professor who majored in engineering design, along with five engineering design experts with a master's degree or higher. The subject of the class was selected as the design and implementation of scientific and engineering measures to reduce marine pollution based on the method implemented in an actual Ocean Clean-up Project. The engineering design process utilized the engineering design model presented by NGSS (2013), and was configured to experience redesign through the optimization process. To verify effectiveness, the STEAM attitude questionnaire developed by Park et al. (2019) and the creative engineering problemsolving propensity test tool developed by Kang and Nam (2016) were used. A pre and post t-test was used for statistical analysis for the effectiveness test. In addition, the contents of interesting points experienced by the learners were transcribed after receiving descriptive responses, and were analyzed and visualized through degree centrality analysis. Results confirmed that engineering design in science classes had a positive effect on both STEAM attitude and creative engineering problem-solving disposition (p< .05). In addition, as a result of unstructured data analysis, science and engineering knowledge, engineering experience, and cooperation and collaboration appeared as factors in which learners were interested in learning, confirming that engineering experience was the main factor.
