To analyze medical professors' evaluation of their online education experiences in an attempt to support faculty members and indicate the future direction of medical education. Faculty members who taught online in the first semester of 2020 at Yonsei University College of Medicine in South Korea were surveyed. The results of the survey were analyzed in June 2020. There were 88 respondents (35.1% of 251): 59 professors (67.0%), 16 associate professors (18.2%), and 13 assistant professors (14.8%). Their specialties lay in basic medicine (25.0%), clinical medicine (65.9%), and research and special purposes (9.1%). Sixteen participants (18.2%) had previous experience in online lectures; 23 (26.1%) reported that preparation time for online lectures was the same as before; 65 (73.9%) reported that the preparation time had increased; 38 (43.2%) faced difficulties in preparation and lecturing online, and among them 16 (42.1%) indicated inadequate interaction with students; 11 (28.9%) needed extra preparation time; and 11 (28.9%) attributed their difficulties to technical issues with the online platform. Participants' satisfaction with online lectures was low (p<0.001). In the free response question on overall experience with online education, 38.3% mentioned the need for an instructional design that allows students to actively participate and interact with professors, 29.5% mentioned the need for the establishment of an information & communications technology system, and 17.0% mentioned the necessity of faculty development. To prepare for the current pandemic and more in the long term, an appropriate educational support system must be constructed, and a learner-centered instructional design that enables wider interactions and active learning is needed.

Capstone Design, a project-based learning technique, is the most important curriculum that clarifying major knowledge and cultivating the ability to apply through the process of solving problems in the industrial field centered on the student project team. Accordingly, various and extensive studies are being conducted for the successful implementation of capstone design courses. Unlike previous studies, this study aimed to quantitatively analyze the opinions that recorded the experiences and feelings of students who performed capstone design, and used text mining methodologies such as frequency analysis, correlation analysis, topic modeling, and sentiment analysis. As a result of examining the overall opinions of the latter period through frequency analysis and correlation analysis, there was a difference between the languages used by the students in the opinions according to gender and project results. Through topic modeling analysis, 'topic selection' and 'the relationship between team members' showed an increase in occupancy or high occupancy, and topics such as 'presentation', 'leadership', and 'feeling what they felt' showed a tendency to decreasing occupancy. Lastly, sentiment analysis has found that female students showed more neutral emotions than male students, and the passed group showed more negative emotions than the non-passed group and less neutral emotions. Based on these findings, students' practical recognition of the curriculum was considered and implications for the improvement of capstone design were presented.

This study aims at investigating the perceptions of science teachers about the role of visual representations in the teaching of electromagnetism, and finding out how science teachers use visual representations in their teaching of electromagnetism and the difficulties they experience in dealing with those representations. A total of 121 science teachers responded to the online survey. The results showed that most of the teachers agreed to the significance of using visual representations in the classroom but regarded their role as means of simply delivering science knowledge rather than constructing or generating knowledge. For the three visual representations widely used in teaching of electromagnetism in secondary schools (electrostatic induction on electroscope, magnetic field around current carrying wire, structure and principle of electric motor), the teachers preferred teacher-centered use of visual representations rather than student-centered and teacher's construction of representations were the most frequent among four types of use; interpretation, construction, application, and evaluation. The difficulties of teaching with these three visual representations were categorized into several factors; teachers, students, the characteristics of the representations, and lack of resources and classroom environment. Teachers' limited perceptions about the role of visual representations were associated with the ways of using visual representations in their teaching. Implications for the effective use of visual representations for science learning and teaching were discussed.

The purpose of this study was to collect information for the improvement of sewing practice classes and to draw implications by carrying out an investigation into the perception and needs of 185 students in the first grade of high school for sewing practice classes. The results of the study are as follows. First, most of the students perceived that the instructional objectives of the practicum as the utilization in everyday life. The students' perception of the class was moderately positive. In terms of the subfactors, the participation level appeared to be the highest while the comprehension level was the lowest. Also, the utilization level showed the greatest difference between male and female students. The results suggest that female students were more positive in their perception of the class than the male students because of the significant difference in the subfactors of class perception, excluding utility and teaching learning method satisfaction. Second, it appeared that the students were likely to use these skills in everyday life as a result of the sewing practice classes. In terms of the practice content, students preferred working individually in terms of organizing their own projects, making their own selections, and freely deciding the size of their products. This study demonstrated that the students preferred teacher-centered classes when acquiring skills and knowledge and student-centered classes when brainstorming and performing the teacher's role. In terms of instructional management, the students preferred four to six 50-minute long lessons per semester and no group work involved.

The purpose of this study is to examine the problems in the teaching practice of beginning science teachers who participated in the collaborative mentoring program to improve their teaching expertise. The participants were six beginning science teachers and six mentors at middle and high school levels. From each beginning science teacher and mentor teacher, journals, one-to-one mentoring records and transcripts, interviews and questionnaires, and transcripts conducted at the beginning, middle and the end of the mentoring program were collected. Seven aspects of the beginning science teachers' problems in their teaching practice were identified. The result showed that mentee teachers didn't set up specific learning objectives and they organized and presented lesson contents without considering students' proficiency level. Also, they found it hard to prepare for the lessons irrelevant to their major field of study and they tended to use convergent questions more than divergent questions. Mentee teachers tend to give teacher-centered rather than student-centered teaching. Beginning teachers' recognition of their problems in their teaching practice tends to lead changes in their teaching practice. Some of the problems that mentee teachers showed could be overcome if they recognized the problem through the collaborative mentoring program, but if not, it tends to remain throughout mentoring program.This study also highlighted the importance of reflection on beginning science teachers' practice.

The purpose of this study was to investigate the change in beginning science teachers' inquiry-oriented teaching practice through mentoring program. Participants in this study are three mentor teachers and three beginning teachers. The three beginning teachers are middle school science teachers who have less than four years teaching experience. Also three science teachers participated in the program as mentors, who have more than twelve years teaching experience. We collected data such as video recordings of beginning teachers' classes, lesson plans, recordings of one to one mentoring and RTOP class observation reports. Mentor teachers observed and analyzed five classes of each beginning teacher. Before the mentoring program, beginning teachers' teaching methods were more concept-oriented and teacheroriented. They rarely used inquiry-elements including prediction, reasoning, hypothesizing and students were not actively engaged in communicative interactions in a classroom. But during the mentoring program, these teachers recognized and responded to student diversity and encouraged all students to participate in science learning. Beginning teachers' teaching methods have changed to become student-oriented, teachers and students collaborated in pursuit of ideas, and students often initiated new activities relevant to an inquiry. As a result, this mentoring program provided beginning teachers the opportunities to reflect on their own teaching and reform their classes. The results show that school-centered mentoring program is helpful to enhance beginning science teachers' inquiry-oriented teaching ability.

The purpose of this research is to derive competencies necessary for students with future convergent STEAM talents, and to explore ideal student images, teaching-learning strategies, evaluation methods, and teachers' competencies and their training methods for future schools developing students' competencies. In order to figure out the features of the future schools, 25 experts from related fields, including in-service teachers, administrators, and college students in science and technology, participated in a future workshop. According to the results, students with future convergent science and technology talents are expected to have flexible thinking and creative thinking competencies to solve problems in innovative ways rather than traditional ways. In other words, it takes the power to accept and accommodate unexpected situations and solve problems appropriately in those situations. To cultivate such competencies, therefore, future schools should also be flexible and proactive. Rigid schools delivering knowledge-based information make it impossible to cultivate flexible and creative talents. Future schools should change into leaner-centered project-based classes so that students can naturally cope with various situations and solve large and small problems, and prepare assessment systems that can provide feedback based on the student's performances rather than achievement standards.

As we have become more interested in 'competency' that means ability to do something around the world, the competency of the best performers has also been introduced in the university curriculum as a concept of core competency. Research continues on why this competency-based education is needed compared to existing academic-oriented education, how it can be introduced into existing curricula, and how it can be developed and evaluated in detail. This study develops and validates core competency assessment tools that can diagnose core competencies of engineering students. Therefore, this research paper conducted a literature review related to core competencies and also core competency assessment tools of university students. It seeks to explore the implications of core competency assessment tools for engineering students and then lay the foundation for competency-based teaching and learning at engineering colleges. And also it defines the concepts of core competencies and each core competency of engineering students through prior research analysis of competence, core competence, and core competence of university students. The primary core competency assessment tool consisted of sub-factors and questions of core competencies. It were modified through the expert validation of the primary one and then it was used as a core competency assessment tools for preliminary investigation. The core competency assessment tools for engineering students are consisted of 6 competencies, 22 sub-factors, and 91 questions. There are core competencies as follows: engineering basic competencies, major engineering competencies, self-management competencies, communication competencies, interpersonal competencies, global competencies. The preliminary survey was conducted on 426 engineering students attending the Engineering Education FESTA 2019. The preliminary findings were derived by conducting exploratory factor analysis, confirmatory factor analysis, question characteristics analysis, and reliability analysis for validation. The core competency assessment tools developed through this study can be used to verify the effectiveness of the curriculum and programs for students at engineering colleges. In addition, the developed core competencies, sub-factors, and questions can be utilized in a series of courses that design, conduct, and evaluate engineering curricula and programs as competency-based curriculum. The significance of this study is to lay the groundwork for providing competency-based education engineering students to develop core competencies.

In this study, we explored science teachers' perceptions of adaptive practice in terms of importance and practice. For this purpose, an adaptive practice questionnaire was developed targeting secondary science teachers, and the responses of 128 science teachers were analyzed. The results of this study were as follows: First, the science teachers responded that all 17 items regarding adaptive practice were important. In particular, items related to 'addition of examples', 'adjustment of the level/range of concepts', and 'encouragement of student participation' showed high importance and performance levels. Second, the results of the IPA concerning adaptive practice showed that the items needing intensive improvement due to high importance but low performance were 'encouraging students' self-directed learning' and 'monitoring and responding to individual differences'. The science teachers identified a lack of time and uniform curriculum as the reasons for the low level of practice despite the high importance of these items. Third, regarding the IPA of the adaptive practice items, the items located in the fourth area, an excessive area, concerned 'pace control', 'modifying activities', and 'metaphor use'. More specifically, considering that 'metaphor use' was the only item with a higher level of performance than importance, it is necessary to reconsider whether problems are caused by excessive use. Fourth, analyzing the responses regarding the reasons for the difference in importance and performance revealed that the factors related to teachers included teachers' lack of knowledge or ability, and the tendency to implement as planned. As for student factors, an excessive number of students, differences in the levels of students, and a tendency to prefer classes centered on entrance exams were identified. As environmental factors, a uniform curriculum, conditions for experiments, evaluation systems, and external demands were mentioned. Finally, the implications of the results of this study for science education were discussed.

In this study, KTOP (Korean Teaching Observation Protocol) was applied to teaching practicum for improving pre-service teachers' science teaching. To do this, four pre-service teachers and supervisor teacher observed and analyzed the lessons using the KTOP, and tried to improve he succeeding lessons through collaboration activities. As a result, the pre-service teachers conducted the collaboration activities based on the lesson analysis using the KTOP, therefore it was concluded that the KTOP took a practical role of guidance for improving pre-service science teachers' teaching. And it was found that the collaboration activities using the KTOP helped the improvement of the succeeding lesson, however, more iterative application is necessary for more effective improvement of teaching. Based on the analysis of questionnaire, observation, and interview, it was found that pre-service teachers need to be confident about the use of the KTOP and strive to become a student-centered lesson. And, the KTOP needs to be modified by reducing the number of items and as a more convenient form. Finally, it was inferred that we need to give an effort to help students recognize that learning should be self-directed.
