This study developed teaching-learning materials for mathematics and coding convergence classes using Python, focusing on 'Prime Factorization' of seventh graders. After applying the teaching methods and contents to the students, they analyzed whether the learners achieved their learning goals. The results were used to modify and supplement teaching and learning materials. Affective domain of learners were also analyzed. The results are that the teaching methods and contents of the developed teaching-learning materials were generally appropriate for learners. The learners understood most of the lessons according to the set teaching methods of all classes. And learners have mostly reached their learning goals. In addition, as a result of analyzing the definition characteristics of learners through follow-up interviews, the interest in mathematics and programming has improved. The developed teaching and learning materials of this study are well consisted mostly of the teaching methods and the contents of the classes, and are organized so that learners can reach most of the learning goals. It also brought positive changes to the affective domain of mathematics and coding, demonstrating the potential for useful use in school.

The purpose of this paper is to apply the newly developed SICAT teaching and learning model to the actual scene of teaching and learning and draw a point of discussion for utilizing teaching and learning model, by uncovering the satisfaction of students and the inhibiting/facilitating elements when using the model. SICAT(Scientific Inquiry and Creative Activity with Technology; from here on SICAT), a teaching and learning model custom-built for engineering education, was developed, as more and more people paid attention to the demand for creative engineers. It was developed from the basis of PBL(Problem Based Learning), includes three sub-types which can be applied to the actual theory, design, and experimentation fields within engineering education. The three sub-types, which are ARDA(Analysis-Reasoning Activity & Discussion-Argumentation Activity), CoCD (Collaboration Activity & Capstone Design Activity), and ReSh(Reflection Activity & Sharing Activity), respectively support deductive and argumentation activities, creative design and collaboration activities, and retrospection and sharing activities. However, no research has been conducted to investigate whether or not there are inhibiting or facilitating elements in the application procedure, or what the rate of satisfaction for students is, when applying the SICAT model, which was newly developed to innovate existing engineering education, to the actual site of teaching and learning. Therefore, this research applied three types of SICAT teaching and learning models to the theory, design, and experimentation classes at the department of materials science and engineering at Hanyang University for eight weeks. After application, the students, teachers and tutors were surveyed and interviewed, and then the results analyzed in order to uncover inhibiting/facilitating elements and the rate of satisfaction. The satisfaction rate of students from the SICAT teaching and learning model was 3.78(in a perfect score of 5: The A type-3.65, The C type-3.80, The R type-3.90), and inhibiting/facilitating elements were drawn from the aspects of learning activities, support system. In conclusion, they can be contributed for implications of SICAT teaching and learning model universal use at engineering education in University.

The purpose of this study was to examine the pedagogical content knowledge(PCK) and teaching efficacy levels of prospective Home Economics teachers. Also of interest were the relationship between PCK and teaching efficacy, as well as the personal factors that influence PCK and teaching efficacy. A survey was administered to students majoring in Home Economics in colleges of education or graduate schools of education in South Korea, and a total of 202 complete responses were analyzed. The prospective Home Economics teachers showed moderately low levels of PCK and teaching efficacy. Among the PCK subcategories, the mean score for content knowledge was the highest, those for expression knowledge and environmental situation knowledge were the lowest. Expression knowledge and content knowledge showed significant effects on teaching self-efficacy, and expression knowledge and environmental situation knowledge on teaching result expectation. As for students' personal characteristics, years in college showed significant effect: Sophomores were the highest in PCK and teaching efficacy levels. Also, those who plan to become Home Economics teachers showed significantly lower levels of PCK and teaching efficacy perception than those who do not. Besides, the more basic required courses they took, the lower their perception of PCK or teaching efficacy. This study suggests that teacher education programs should develop a program that can enhance prospective teachers' teaching efficacy by providing advice and assistance to those students who plan to become teachers, and more hands-on opportunities to practice teaching.

An expert teachers' instruction can be helpful to other teachers because good teaching effectively guides students to develop meaningful learning. Feynman is an excellent physics lecturer as well as one of the greatest physicists of the 20th century who presented and explained physics with his unique teaching style based on his great store of knowledge. However, it is not easy to capture and visualize teaching because it is not only the complex phenomena interrelated to various factors with the content to be taught but also the tacit representation. In this study, the framework of knowledge & belief based on the integrated mental model theory was used as a tool to capture and visualize complex and tacit representation of Feynman's teaching of 'The theory of gravitation,' a chapter in The Feynman Lectures on Physics. Feynman's teaching was found to go beyond the transmission of physics concepts by showing that components of the framework of knowledge & belief were effectively intertwined and integrated in his teaching and the storyline was well-organized. On the basis of these discussions, the implications of Feynman's teaching analyzed within the framework of knowledge & belief for physics teacher education are derived. Finally, the characteristics of the framework of knowledge & belief as tools for the analysis of teaching are presented.

We compared and analyzed the changes in students' science grades and their effects on science grades by level (upper, middle, and lower) according to non-face-to-face and face-to-face teaching-learning. 66 students from A Middle School in Gyeongsangnam-do were selected for the study. As a result of analyzing the change in science grades according to the teaching-learning type, the average score of science grades by non-face-to-face teaching-learning was lower than the corresponding score of science grades of face-to-face teaching-learning. As a result of comparing the level of understanding of learning content according to the evaluation type (paper-written, study-paper) in non-face-to-face and face-to-face teaching-learning, the average scores of science grades by paper-written and study-paper evaluations in non-face-to-face teaching-learning were significantly low. In addition, as a result of comparing the effect on science grades by level according to the teaching-learning type, the average score of science grades of lower-ranked students in non-face-to-face teaching-learning was relatively low.

This study analyzed the change of teaching expertise of pre-service teachers through TPACK education. In this study, we applied a programming-based TPACK education program developed by Kim and Lee (2019) to 20 prospective teachers. To analyze the pre-service teachers' teaching expertise analyzed the lesson plan prepared before, during and after applying the educational program. As a result, Few teachers use technology in lesson plan, and the design of the instructor-led or experiment to confirmed content in curriculum or textbook. The use of technology has increased in the second Teaching Plan, but the technology was not used depending on the educational context. In the third lesson plan, all pre-service teachers were able to use technology in an educational context. Moreover, the teaching expertise of the pre-service teacher showed a statistically significant improvement in the lesson plan. This study founded that the programming-based TPACK education program was effective in enhancing the teaching expertise of the pre-service teacher.

Teaching and learning were carried out long before the word "education" was coined. As teaching and learning became more universal, the word "education" was construed as a social promise, and there was a general consensus as to what it denoted. Many university professors will most likely have great confidence and expertise with respect to "teaching" in their area of specialization, and they believe that they are fulfilling a social promise. However, how much expertise do they have in actually making students "learn"? How concerned are professors about enabling students to utilize their potential and talents to cultivate their learning abilities and to adjust to the different demands of various fields? The same issue arises in medical education. To what extent can professors' teaching heighten students' sense of purpose and motivation to learn? With regard to increasing learners' initiatives, the learning model of constructivism presupposes that learners are active and creative, have their own personalities, and possess unlimited learning potential. The PBL being carried out in medical schools today is a form of study that can take advantage of these aspects of learners. They can maximally widen the range of students' development through many intellectual activities and solve difficult problems by either sharing or critiquing the thoughts and ideas of others. The acts of teaching and learning that have been carried out for thousands of years remain difficult to this day and must be ceaselessly deliberated and researched by experts in the field of education. Just as good teachers are required to produce good learners, we must give ourselves room to rethink the basis of education in order to maximize effective and efficient learning.

The purpose of this study is to analyze the perception and need of the early childhood education field on authentication of teaching materials and implements for young children. To achieve this, a survey was carried out on 350 teachers and directors in Daejeon-based kindergartens and child-care centers from September 21 to September 30, 2013. The results of the analysis are as follows. First, 59.4% of them thought that it needed the evaluation authentication of teaching materials and implements for young children. 32.9% of them had a high perception of the early childhood education field. 39.4% of them had high need of the early childhood education field. And 45.1% of them expected a high effect of introducing the evaluation authentication system of teaching materials and implements for young children. Second, most of them had the highest need of the evaluation authentication of teaching materials and implements for young children in terms of education, followed by function and field. And most of them placed the highest emphasis on social development, safety and language in terms of education, function and field, respectively. Consequently, the use of teaching materials and implements, which the social development and safety in terms of education and function are respectively evaluated and authenticated by the diversity of teaching materials and implements for young children, has need of the high evaluation and authentication of teaching materials and implements that can guarantee the quality when young children use a lot of experiment and observation implements such as block play, reading materials, manipulating materials, making implements.

In this study, we applied a web-based education system to the teaching-demonstrations of the pre-service teachers and identified the usefulness of the system as a method supporting constructive education for pre-service teachers. The pre-service teachers performed the web-based activities for the teaching-demonstrations, and we interviewed them after the teaching-demonstrations. On the basis of the results, we found three situations showing the usefulness of the web-based education system. First, the pre-service teachers examined the materials on the constructive teaching-learning theories and constructed the related theoretical knowledge. At this point the web-based discussion board supported the environment where they thought deeply and investigated the theories carefully. Second, they experienced interaction with others and the academic adviser in the processes of preparing the teaching-demonstrations. This interaction was supported by web-based discussion board, and they were able to form the practical knowledge related to the planning and building constructive teaching. Third, they reflected on their own teaching after the teaching-demonstrations. At this point, the web-based discussion board was able to facilitate the interaction for the reflective thinking processes. In this study, we identified that the web-based education system could provide an effective environment where the pre-service teachers could learn constructive teaching-learning methods.

As a case study on beginning teachers' teaching professionalism in science-gifted education, we analyzed their teaching professionalism based on pedagogical content knowledge. To do this, we selected 3 elementary and 3 secondary beginning teachers from science-gifted education institutes in the metropolitan area. After their science instructions for science-gifted students were observed, in-depth interviews were conducted. Analyses were conducted with taped videos, researcher's field notes, and transcripts for in-depth interviews. This study revealed that most of the teachers had relatively desirable belief about science-gifted education. However, they tended to have a little deficient practical knowledge about science-gifted students, the curriculum for science-gifted education, science contents, the instructional strategies for science-gifted education, and the assessment in science-gifted education. These results imply that many teachers are likely to have a little deficiency in teaching professionalism for science-gifted students in various aspects, and need to find the ways of improving their teaching professionalism.
