학생들에게 사고의 다양성과 창의성을 신장시킬 수 있는 가장 좋은 대안의 하나가 정보통신기술(ICT)을 활용한 수업을 들 수 있는데 아직까지 정보통신 기술을 활용한 수업이 실제적으로 학생들에게 어떠한 인지적, 정의적 영향을 미치는가에 대한 구체적인 연구결과는 없다. 따라서 상호작용이 풍부한 ICT 활용 수업이 정보화 사회가 요구는 자기 주도적 학습 능력을 얼마나 신장시키는지를 규명하기 위해 ICT활용 수업을 실시하기 위한 기초 자료를 제작한 후 홈페이지를 통한 정보 안내하기, 인터넷을 활용한 문제해결학습, 정보분석형 가상실습, 공동 협력 프로젝트 수업, 웹토론형 수업을 실시하여 ICT활용교육이 정보활용, 정보검색 능력, 학업성취도 향상 등에 어떠한 영향을 미치는지를 연구하였다.

본 논문에서는 실시간 원격 수업(Real-Time Distance Education) 환경 하에서 학생들의 수업 집중 및 효율적인 교수를 위한 버즈학습(Buzz Learning)의 필요성을 제안한다. 이 학습법은 실시간 원격 수업에서 일어날 수 있는 집중력 저하 및 수업참가율 저조를 최소화하고, 학습자 간의 협동 및 상호작용을 향상시킨다. 또한 버즈법에 의한 그룹 편성 및 학습형태는 각 그룹에서 토의한 결과를 다시 전체가 모여 토의함으로써 소집단의 토의결과를 종합 정리하고 결론을 도출해 내는 집단 토의 형태를 띤다. 토의학습은 흔히 몇몇 학생의 경우 토의에 참가하지 않거나 또는 한 명이 독무대화하는 경향이 있는데 여기서는 그룹 전원이 토론에 적극 참여할 수 있게 한다. 본 논문에서는 실시간 원격 수업을 통하여 이뤄지는 실제 강의에 적용된 버즈 학습이 학생들의 수업참여도 및 학습 향상 면에서 우수함을 보여준다.

코로나 팬더믹의 장기화에 따른 비대면 환경에서 대면 수업의 실재감을 제공하는 다양한 교수·학습 방법에 대한 시도가 이루어지고 있다. 실제 수업 현장에서는 대면수업과 다른 환경에서 학습자의 수준과 특성에 맞는 수업 설계의 필요성 또한 대두되고 있다. 본 연구에서는 플립러닝을 기반으로 한 비대면 프로그래밍 수업에서 학업성취도에 따른 학습 참여 수준과 실재감의 차이를 분석하여, 맞춤형 학습역량 강화를 위한 교수 방안을 모색하는 데 그 목적이 있다. 강의 동영상 수업과 상호작용을 포함한 플립러닝 기반 실시간 수업을 혼합하여 수업한 후 설문을 통해 학업성취도에 따른 학습자들의 학습 참여 수준, 교수 실재감과 학습 실재감을 조사한 결과, 학업성취도 가장 높은 학습자일수록 학습 참여도 높고, 다음 수준의 학습자들이 교수 실재감과 학습 실재감은 가장 높은 것으로 조사·분석되었다. 이를 통해 학업성취도에 기반하여 학습자별 맞춤형 교수방안을 제시하였다.

Teacher knowledge needed for teaching is bound to be revealed in teaching the subject matter in relation to the given instructional context. Given this, recent studies on mathematics teacher knowledge tend to analyze actual Mathematical Knowledge in Teaching [MKiT]. This study focused on the dimension of transformation and its related codes in Knowledge Quartet, which has been recognized as a MKiT framework, and analyzed a Korean teacher's transformation knowledge revealed in her elementary mathematics teaching. The analysis showed that the codes related to the dimension of transformation were useful in analyzing teacher knowledge in the Korean context. However, a few codes need to be revised or added for more suitability. On the basis of these results, this paper closes with implications for analyzing teacher knowledge in mathematics teaching.

The purpose of this study was to understand PCK to improve professionalism of teachers and derive implications about proper teachings methods. For achieving these research purposes, different PCK and teaching methods in class of three teachers(A, B, C) were compared and analyzed targeting division of decimals for 6th grade. For this study, criteria of PCK analysis of teachers was set, PCK questionnaires were produced and distributed, teachers had interviews, PCK of teachers were analyzed, division of decimals class for 6th grade was observed and analyzed, and PCK of teachers and their classes were compared. The implications deriving from comparative analyzing PCK and classes are as follows. First of all, there was a close relation between PCK and classes, leading to a need for efforts of increasing PCK of teachers in every field in order to realize effective classes. Secondly, self study and in-service training are needed to enhance PCK of teachers. Thirdly, more of expertises and materials have to be provided on the instruction manual for teachers.

This study aims to develop and apply problem Based learning classes through skin beauty basics and practical classes to foster experts close to the beauty care field. Students are presented with a problem to solve in practice in the field of skin care, and in order to solve the problem, intellectuals try to come up with a solution to solve the problem jointly. Conduct skin beauty learning classes that apply problem-based learning to students, and analyze the effects after taking the classes. As a result of this study, by presenting actual problems in the field, scientists were able to actually do what experts do, and it was possible to come up with various solutions to a given problem in the future, and to share parts to expect problem-solving abilities. These results suggest that problem-solving and the problem-centered learning process for problem-solving have a positive effect on improving his problem-solving ability.

The purpose of this research is to estimate the chemistry teacher's perceptions of Chemistry I course based on the 7th national curriculum through actual class teaching situations and interviews and teaching guidance of an actual class through a lesson and an interview. For this research, four chemistry teachers who have had an experience teaching the chemistry I course were selected. As the results of the research show, chemistry teachers had the correct understanding of the purpose of the Chemistry I course, but they were teaching the concepts of Chemistry II . They thought the reason for the teaching was the national scholastic aptitude test. But according to analysis, the contents of the previous tests were hardly beyond the limit of Chemistry I course. For this research, the chemistry teachers looked for the purpose of Chemistry I course based on the 7th curriculum only at the superficial views, and the teacher's wrong understanding about the tests disturbed the revelation of the spirit of Chemistry I course of the 7th national curriculum.

To implement effective technology-based education, we need knowledge for functional aspects of technology as well as design and procedural aspects of curriculums. Also, we need positive teaching efficacy. In this regard, we investigate the effects on teachers' TPACK and technology teaching efficacy on mathematics after make the teachers design and teach technology-based classes according to the ASSURE model which is suitable in designing technology-based educations. First, we let the teachers design and teach two unit hour classes. The first class had been done with the teachers learned functional aspects of technologybased educations, and the second one with them designed based on the steps in the ASSURE model. To analyze the effects of ASSURE model, we have performed a case-study for one teacher who had taken part in our college class. As a result, we conclude that the teacher's experiences in designing classes based on the ASSURE model help improve the teacher's TPACK and technology teaching efficacy on mathematics in a positive way.

This study presents the process and outcomes of developing mathematical-informatics linkage·convergence class materials, based on previous research findings that indicate a lack of such materials in high schools despite the increasing need for development of interdisciplinary linkage·convergence class materials In particular, this research provides insights into the discussions of six teachers who participated in the same professional learning community program, aiming to create materials that are suitable for linkage·convergence class materials and highly practical for classroom implementation. Following the material development process, a theme-based design model was applied to create the materials. In alignment with prior research and consensus among teacher learning community members, mathematics and informatics teachers developed instructional materials that can be utilized together during a 100-minute block lesson. The developed materials utilize societal issue contexts to establish links between the two subjects, enabling students to engage in problem-solving through mathematical modeling and coding. To increase the validity and practicality of the developed resources during their field application, CVR verification was conducted involving field teachers. Incorporating the results of the CVR verification, the finalized instructional materials were presented in the form of a teaching guide. Furthermore, we aimed to provide insights into the trial-and-error experiences and deliberations of the developers throughout the material development process, with the intention of offering valuable information that can serve as a foundation for conducting related research by field researchers. These research findings hold value as empirical evidence that can explore the applicability of teaching material development models in fields. The accumulation of such materials is expected to facilitate a cyclical relationship between theoretical teaching models and practical classroom applications.
