대학은 강좌에 대한 총체적인 가치를 정확하게 측정, 평가하여 효과적인 교육이 일어날 수 있도록 하여야 한다. 강의 평가는 강사로 하여금 강의의 질과 문제점을 인식시키고 강의의 질을 향상시킬 수 있는 기회를 제공할 뿐 아니라, 학생들에게 효과적인 학습의 기회를 제공할 수 있다. 본 논문에서는 공학교육 강의 평가의 특성에 관하여 전반적인 고찰을 수행하였다. 특히 평가의 요소 및 속성 그리고 평가방법에 따른 효과와 문제점 등을 조사하였다. 효과적인 강의 평가 운영법 및 타당성에 대하여서도 연구 및 제안하였으며, 명지대학교 학생들을 대상으로 강의 평가에 대한 설문조사를 통해 그 결과를 분석하였다.

The purpose of this study was to develop an indicator of core competency of freshmen of an Institute of Science & Technology (IST). Through the document analysis and the expert survey, core competency indicators that include 5 core competencies and 15 sub-competencies (a total of 48 items) were developed. Then content validity was examined by experts in measurement and statistics and secondary education. Also, by using students' responses, reliability was tested with Cronbach's alpha and construct validity were tested through confirmatory factor analysis. Results suggest that the core competency indicator is reliable and valid in measuring core competencies of freshmen students in an Institute of Science & Technology. Discussions were provided in terms of improving student admission processes.

Grewia serrulata fibres were chemically treated with 3%, 6%, and 9% NaOH for the duration of 4 h. Additionally, the NaOH-treated fibres were also treated with 3 - (trimethoxysilyl) propyl methacrylate (silane). Properties such as density and tensile strength of the treated fibres were compared against the untreated fibres. The highest density was obtained in the case of 9% NaOH + silane treated fibres, which was 26.47% higher than untreated fibres, implying effective removal of hemicellulose. Likewise, the highest tensile strength was also obtained in the case of 9% NaOH + silane treated fibres. The increment observed in the tensile strength of the natural fibres was related to the removal of impurities, hemicellulose, and stress-raisers as well as deposition over the fibre surface that smoothed it. These observations were further validated by estimating changes in chemical constituents due to chemical treatment along with characterization techniques such as scanning electron microscopy and thermogravimetric analysis.

This study aims to examine the differences between groups through the results of the core competency diagnosis, and to find out the differences in core competences depending on engineering education accreditation, gender, admission types. To this end, we analyzed the differences in K-CESA results on self-management capabilities, resources & information use, global competency, higher order thinking competency, and interpersonal competency in 2017 for the fourth graders of S University. An ANOVA of major field showed that the humanities had high overall competencies. The results of t-test of engineering students showed that accredited students had relatively low "flexibility" of their global competency, and that the "analysis" of their higher order thinking competency was relatively high. There were no statistically significant differences between groups depending on the admission types. Through these analyses, we presented suggestions such as the provision of specialized programs based on differences among different groups, the development of comprehensive thinking skills such as capstone design, the need to secure flexibility in engineering education accreditation, and the enhancement of female students' resources & information use.

The main purpose of this study was to develop a program outcomes assessment tool using reflection journal. Reflection journal has recently come to gain more attention from school as an alternative assessment tool. Although numerous studies reconfirmed the educational importance and value of reflection journal as an assessment tool, research on the assessment tool of the engineering accreditation, based on education view is scarce. After literature reviews about the case studies on the program outcomes assessment, this study, to analyse the current assessment tools, and then, examined the educational implications of reflection journal as a program outcomes assessment tool. This study suggested the assessment tool using reflection journal for PO6 (teamwork) and PO11 (engineering ethics), one of the most important assessment items in engineering accreditation. In this study, we used the performance criteria, assessment criteria, rubric, and closed the loop to measure the teamwork and engineering ethics. The result of this study is significant in terms of guiding the future evaluation system development for program outcomes.

The purposes of the study were to examine engineering students' concerns and problems while they were choosing a project topic in interdisciplinary collaboration and to suggest ways to support them in an early stage of collaboration phase. To answer the research questions, we conducted a case study with engineering participants in GCTI 2015, an interdisciplinary collaborative and creative group project. Multiple data sources including focus group interviews, online survey and researchers' observation notes were used to triangulate research findings. We found four main concerns of engineering students. These concerns include (1) lack of self-efficacy, (2) limited resources, (3) lack of shared, meaningful, and common goals, and (4) lack of content knowledge. Based on these concerns we proposed four supports in an early stage of the collaborative project. These supports includes (1) implementing an orientation program, (2) providing opportunities for social interactions, (3) providing expert feedback, and (4) providing consultation for team building.

The purpose of this study is to provide a direction for domestic engineering education research by analyzing the research trends of JEE(Journal of Engineering Education). The results of analyzing research trends regarding research topics, research objects and research methods are as follows. First, by research topic, 'Diffusion of Educational Innovation' was found to have the highest proportion with 52 articles(21%). Second, by research objects, 'university students' showed the highest proportion with 148 articles(53.6%). Third, by research method (large category), 'quantitative research' had the highest proportion with 132 articles(53.2%). By research method (medium category), 'survey research' had the highest proportion with 129 articles(33.5%). Based on the results of this study, future engineering education research should be conducted to contribute to holistic development through diversification of research topics, methods, and objects.

The purpose of this paper was to develop an instructional design model and checklist for AI education. Literature review was conducted to derive the structure of the instructional design model. And delphi survey was conducted twice to revise and improve the elements & items of the instructional design model and checklist and to confirm the content validity of both instructional design model and the checklist. As a result, an instructional design model consisting of three main steps(Analysis - Design & Development - Implementation & Evaluation) was suggested with a detail checklist which explained what teachers need to do in each step of this instructional development model when they prepare AI education using this instructional design model. Limitations and suggestions for further studies were presented at the end of this paper.
