This study aimed to introduce a case study of a basic engineering design course using the ENACT model for fostering social responsibility of engineers, and to investigate the educational effects of the course. Since the ENACT model was designed to encourage STEM college students to pursue responsible problem solving based on their understanding of socioscientific issues, we assumed that it would be beneficial for engineering students to foster their social responsibility as well as their understanding of science/engineering-related issues. A total of 49 engineering students who enrolled in the course participated in the study. Data included students' course artifacts, reflection papers, and responses to survey questionnaires. Results indicated that the students became more aware of nature of science and technology after the program, and began to solve the problems while considering the views of multiple stakeholders. They highly valued the experience of communicating with others as engaging in the civic activities. They also expressed high satisfaction and feeling of achievement on the course learning. We expect the ENACT model to be an effective teaching guideline that fosters the social responsibility of engineering students and furthermore, engineering ethics.

In modern society, as technology develops and industry diversifies, students can choose from a variety of career paths. Since science, technology, engineering, and mathematics require a longer education and experience than other fields, it is important to design science education policies based on the competencies required for science, technology, engineering, and mathematics (STEM) occupations. This study explores the definition of science and technology manpower and STEM occupations and identifies core competencies of STEM occupations using standard job information operated and maintained by the US Department of Labor ($O^*NET$). We specially analyzed ratings of the importance of skills (35 ratings), knowledge (33 ratings), and work activities (41 ratings) conducting descriptive analysis and principal component analysis (PCA). As a result, core competencies of STEM occupations consist of STEM problem-solving competency, Management competency, Technical competency, Social service competency, Teaching competency, Design competency, Bio-chemistry competency, and Public service competency, which accounts for 70% of the total variance. This study can be a reference for setting the curriculum and educational goals in secondary and college education by showing the diversity of science and technology occupations and the competencies required for STEM occupations.

The purpose of this study was to develop educational programs of STEAM-based project under the theme of "Photography of Earth" for the circle activities of the creative experiential activity, to be applied this program to them and to identify technology subject self-efficacy and change in attitude toward engineering. In order to achieve the research objectives, this program was applied to middle school student in Cheonan, STEAM-based circle during 9 class instruction. The results of this study are as follows. First, the STEAM program contents for circle activities were selected through utilizing a five-stage design model(preparation, design, development, implementation and evaluation) and analyzing the curriculum. After that we have developed a teaching plan, STEAM-Story, student activity sheets from the viewpoint of cultural fusion and have applied the circle activities of the creative experiential Activity during 4 months. Second, The result of the test(pre- and post-test) about STEAM program that has been developed were different about technology subject self-efficacy and attitude toward engineering. Therefore, we have verified that the effect of the STEAM-based project under the theme of "Photography of Earth" for the circle activities on the attitudes toward engineering and self-efficacy in middle school is effective.

The curriculum of programming education including algorithm has been recognized as a very important subject to many students majoring in natural sciences and engineering including electronic engineering and computer related departments. However, many students have had difficulties with it due to its characteristics; as a consequence, they have been in trouble taking upper-level subjects. Flow chart is a diagram that expresses logical stages necessary to solve certain problems and has been widely used to have an understanding of the flow of algorithm. The practice-oriented education of algorithm and programming would be very important to assist the understanding of operation processes. Furthermore, it has been desperately required to the necessity of auxiliary programs that could enhance an understanding of the concept of algorithm and program execution process. This study was aimed to design and embody the learning system of programming languages using basic algorithms so as for students to easily learn basic algorithm among the entire programming curriculum.

It is strongly desirable to continuously study the program outcomes that are one of the requirements of engineering accreditation. In this paper, the results of program outcome evaluation obtained by using four tools - exit written exams, essay tests, capstone design, and an official English test - were compared to those of program outcome evaluation obtained by a course-embedded assessment method. The former evaluation was carried out for 15 students who graduated in February 2010 by using the four evaluation tools, while the latter was performed by using a course offered in the Spring and Fall semesters in 2009. Two evaluation results revealed no large difference in almost all 12 program outcomes, which indicates that course-embedded assessment would be one of the practical and effective program outcome evaluation tools.

ABEEK recommends convergent engineering projects to nurture creative problem-solving ability for 1st year engineering students through 'Creative Engineering Design' course. However, 1st year engineering students, who have not yet studied core subjects in engineering, have difficulties understanding and coping with the challenges posed by the engineering-related projects. For this reason, the educational objectives of this course are usually frustrating to achieve by the instructor. In this paper, by using the problem-solving process and skills of critico(-creative) thinking, we prepare guidelines for creative engineering design education that allow 1st-year students to effectively participate in engineering projects without a complete understanding of the design process which is to be studied. Also, we present a case study that applies the guidelines to an on-going creative engineering design course and discusses the outcomes by showing student-generated works. The results showed that the intuitive content and everyday expression of critico(-creative) thinking education enabled the instructor to effectively guide their students through the requirements of engineering projects without relying on advanced engineering design methods, and that the application of these guidelines also helped improve students' communication skills, including presentation. We show that the guidelines for creative engineering design education utilizing the problem-solving process and skills of critico(-creative) thinking is not only contributing to achieving the educational objectives of the creative engineering design course but can also be an educational paradigm that incorporates critico(-creative) thinking education into engineering education.

Usability heuristics("heuristics") are general principles for usability evaluation during user interface design. Our ultimate goal is to extend the practice of usability evaluation methods to a wider audience(e.g. user interface designers and engineers) than Human Computer Interaction(HCI) professionals. To this end, we explored the degree to which Jakob Nielsen's ten usability heuristics are understood by professors and students in design and computer engineering. None of the subjects received formal training in HCI, though some may have had an awareness of some HCI principles. The study identified easy-to-understand heuristics, examined the reasons for the ambiguities in others, and discovered differences between the responses of professors and students to the heuristics. In the course of the study, the subjects showed an increased tendency to think in terms of user-centric design. Furthermore, the findings in this study offer suggestions for improving these heuristics to resolve ambiguities and to extend their practice for user interface designers and engineers.
