This study explored the overall perception of teaching media from the perspective of pre-service teachers. For this purpose, reflection journals written by 138 pre-service teachers were analyzed, and positive and negative perceptions of teaching media were explored. In the reflection diary, pre-service teachers were asked to write down examples of appropriate use of instructional media and the effects of their experiences, cases of inappropriate use of instructional media, and areas requiring improvement. The main research results are as follows. First, the positive aspects of teaching media perceived by prospective teachers were that it presented examples that could help understanding, aroused curiosity to focus attention, and encouraged participation to motivate learning. Second, the negative aspects of teaching media perceived by prospective teachers include cases where the playback time of the video containing learning content is excessively long and the content of the video is unclear or is higher than the learner's level and difficult to understand. This study is significant in that it presents pre-service teachers experiences and perceptions of teaching media and their desirable use methods.

The purpose of this study is to identify the teaching professionalism of the two teachers for secondary science-gifted students in perspective of teaching orientations. Both teachers have been taught biology to secondary science-gifted students for more than six years and they have received in-service training in gifted education. Teachers' orientations were investigated through in-depth interviews and observing lessons. For the data collection, videotapes were recorded during two lessons and two in-depth interviews for each participant were conducted. All recorded data were carefully transcribed and analyzed. Some unique characteristics of teaching were identified from the class instruction of each participant. Both teachers revealed 'Open Inquiry' orientation. This was reflected by their educational goals and beliefs that they should help science-gifted students to grow themselves as scientists by enhancing their inquisitiveness and creative problem solving ability. However, each teacher had shown different teaching orientations such as 'Academic Rigor' and 'Discovery' that seemed to have influence on the level or the range of subject matter covered in the classes. Teachers' science teaching orientations have been changed by their subject of teaching and their experiences in teaching the gifted. In the process, teachers' educational philosophy about gifted education plays an important role in teaching orientation. Based on the ongoing teachers' efforts for enhancing his/her professionalism, the teachers seemed to critically review theoretical knowledge of the science teachers in gifted education through self-reflection on their own teaching methods. When teacher's educational philosophy about gifted education was established and internalized, science teaching orientations in teaching practice seemed to be consistent with his/her goal of teaching.

The purpose of this study is to investigate the formation and development of science teachers' practical knowledge by life history. In the sociocultural perspective, a science teacher is a producer and consumer of knowledge. There were two secondary science teachers who participated in this study. Each of them had three to six years experience in teaching. They were familiar with the researchers because they had been to the same university or were colleagues with them in graduate school for several years. The two science teachers had formed their practical knowledge for their professional development based on their biographical backgrounds. Model of Life history and structure of personal practical knowledge were used as analytical tools. As a result, the science teachers' practical knowledge has shown a significant difference in the main concern and weight according to their life contexts. The science teachers' formation of their practical knowledge played a role as an important motive to improve their professionalism based on the teacher's life path. In addition to that, the science teachers' practical knowledge showed a tendency to be solidified with continuous reflection.

This study discussed the major notion of backward design placing emphasis on performance and evaluation, and clarified the concepts of 'understanding' and 'enduring understanding' based on the literature of Wiggins and McTighe and previous studies. This study also developed a sample curriculum module for a consumer unit for 7 class hours based on the 'Understanding by Design' template. This study concluded that backward design can contribute to achieving student's high performance from evaluation planning prior to actual instruction, to utilizing learning with higher order thinking and skills by analyzing key concepts, and to reconstructing curriculum contents considering a teacher's perspective, students' needs, and each school's situation and context.

The information society is characterized by rapidly increasing and changing information. Traditional models of learning and instruct on have emphasized forms of mastering the information in content domains. Storing information and being able to recall it has been central to formal education. But it is no longer possible to master content domains. This paper discusses constructivism as a shifting paradigm for educational research and practice in information society. Constructivism provides an alternative epistemological base to the objectivist tradition. Constructivism holds that there is a real world that we experience. However, the argument is that meaning is imposed on the world by us, rather than existing in the world independently of us. Meaning is seen as rooted in experience. The experience in which an idea is embedded is critical to the individual's understanding of that idea. From the constructivist perspective, learning is not a stimulus-response phenomenon. It requires self-regulation and the building of conceptual structures through reflection and abstraction. Problems are not solved by the retrieval of rote-learned right answers. The effective motivation to continue learning can be fostered by leading students to experience the pleasure that is inherent in solving problems chosen as one's own. Constructivism requires the change of the teacher's role from a knowledge transmitter to a coach or facilitator of student's understanding. Constructivist teachers inquire about students' understanding of concepts before sharing their own understandings of those concepts, and encourage students to engage in dialogue, both with them arid with one another. In Korea, the educational reform called open education has been spreading through out the country. There should be a paradigm shift in learning and instruction from objectivism to constructivism for better educational reform in Korea.

The evaluation of programs related to SW development often only provides the right answer of the student's program. The purpose of this study was to provide the baseline data about the contents of the program evaluation support the teacher's class and which part should be considered important in partial scoring. To accomplish the goal, we had two months of Python lessons for 90 middle school students in free-semester and analyzed 1185 source codes collected during the lessons. Result of analysis, many students made mistakes about syntax errors and teachers considered logic errors as important. Based on the result, it is necessary to reduce the student's syntax errors and teachers need to evaluate student's program with considering the importance of logical aspects and necessary to devise a partial scoring. This study has significance about consideration of program evaluation from the perspective of learning support and evaluation.

Donggang Su-ho Jo(1924-2016, hereinafter referred to as "Donggang") was a calligrapher and literarti painter who was active in recent times. When he survived, he was called the first teacher respected by all in the field of world calligraphy. His perception of beauty is due to the art view embodied by human instinct. In particular, he considered writing and painting as art of contact(接), which means connecting. Therefore, the meaning of contact(接), is recognized as a kiss between men and women or love affair(雲雨之情). In this way, his literarti painting originated from a wide range of concerns and quests for art. He recognized the principle of art creation from a universal and general perspective on beauty. Based on this, the significance of true artistic spirit and art philosophy was established. If you observe the literarti painting of the Donggang with bamboo's literati painting and orchid's literiti painting, his bamboo's literati painting has the aesthetics of lusterless(無潤), and difficulty obscurity(苦澁). His orchid's literati painting is appreciated refinement(雅) and harmony(韻) made vulgar appearance(俗). His character and scolarship became his literarti painting.

The ultimate goal of instruction is for learners to understand contents they have to learn in class. Therefore, shedding light is needed on the characteristics of understanding required by teachers and perceived by students when class is conducted for the purpose of understanding. To do this, 87 middle school teachers were requested to write down questions they asked to improve the understanding of learners in 'reproduction and genesis' unit. They were categorized according to Wiggins & McTighe's six aspects of understanding and a questionnaire was developed based on the data. A survey was conducted on 90 teachers and 370 ninth-grade students. The findings of this study were as follows: First, the teachers demanded explaining, interpreting and perspective a lot, but applying, empathy and self-knowledge were scarcely required. Second, the teachers demanded explaining the most, and the students as well. The next aspect of understanding in both groups was interpreting, followed by perspective, applying, empathy and self-knowledge. There were significant differences among the opinions of the students according to gender (p<0.05). Third, the students persevered explaining, applying and self-knowledge the same way as the teachers demanded, but not for interpreting, perspective and empathy. This study is expected to provide some information to achieve the instruction objectives of understanding successfully.

The purpose of this research is to develop a Home Economics education curriculum that can promote citizenship through critical literacy. To this end, the 'housing' area in the 2015 revised curriculum of home economics and textbooks were analyzed from a critical literacy perspective. Using Laster(1986)'s critical science curriculum development course and "A Teacher's guideFamily, Food and Society"(Staaland & Storm, 1996), a 'Citizenship raising curriculum of home economics education in the housing area.' was developed. The results of this research are as follows. First, when the the curriculum was examined, the teaching objectives of the overall subject, or the achievement criteria, learning elements, and evluative methods of the housing area consisted of practical problem solving curriculum that can include critical literacy content. In addition, as a result of analyzing the text of the three textbooks' housing areas, it was found that most of them were described as adapting to and coping with the current culture, and few problems or social issues were mentioned that could lead to critical literacy. Second, the housing area curriculum for critical literacy learning was developed, with a total of 13 plan of 7 modules including continuous interests, valued ends, learning contents, and 26 learning materials including reading materials, and video materials. Based on the findings, the next curriculum and textbook should address social issues related to critical literacy and various classes of housing, and teachers' communities and training should be operated to support teachers who can be examplary for practical reasoning and critical thinking.

Modern society's technological and economical changes require high-level education that involve critical thinking, problem solving, and communication with others. Thus, today's perspective of mathematics and mathematics learning recognizes a potential symbolic relationship between concrete and abstract mathematics. If the problems engage students' interests and aspiration, mathematical problems can serve as a source of their motivation. In addition, if the problems stimulate students'thinking, mathematical problems can also serve as a source of meaning and understanding. From these perspectives, the purpose of my study is to prove that mathematical modeling tasks can provide opportunities for students to attach meanings to mathematical calculations and procedures, and to manipulate symbols so that they may draw out the meanings out of the conclusion to which the symbolic manipulations lead. The review of related literature regarding mathematical modeling and model are performed as a theoretical study. I especially concentrated on the study results of Freudenthal, Fischbein, Lesh, Disessea, Blum, and Niss's model systems. We also investigate the emphasis of mathematising, the classified method of mathematical modeling, and the cognitive nature of mathematical model. And We investigate the purposes of model construction and the instructive meaning of mathematical modeling. In conclusion, we have presented the methods that promote students' effective model construction ability. First, the teaching and the learning begins with problems that reflect reality. Second, if students face problems that have too much or not enough information, they will construct useful models in the process of justifying important conjecture by attempting diverse models. Lastly, the teachers must understand the modeling cycle of the students and evaluate the effectiveness of the models that the students have constructed from their classroom observations, case study, and interaction between the learner and the teacher.
