Teaching with technology has been widespread in practical classroom settings, and increased the needs to enhance pre-service teachers' capability with a variety of technologies. The purpose of this study is focused on designing and implementing a training program to develop pre-service teachers' Technological Pedagogical Content Knowledge(TPACK) which promotes them use technologies tactically in integrated science classes. Based on the theoretical framework of TPACK and Practitioner's Guide to TPACK, the authors developed ten periods of lessons comprised instructional skills in elementary science education. Subsequently, the program was applied into a teacher trainee course in Korea. The results of this study indicate that the TPACK training program for pre-service teachers significantly influenced on attitude toward convergence, TPACK, and science teaching efficacy of the engaged participants. The developed program, meanwhile, caused a significant TPACK improvement of female participants of the teachers college more effectively. Furthermore, it mitigated the gap between science and humanity tracks coming from their high schools. Consequently, there are possibilities to improve pre-service teachers' teaching strategies for integrated classes, if they have opportunities to review the comprehensibility of technological, pedagogical, content knowledge, and intersected areas with metacognitive perspectives.

Secondary school environmental education is offered mostly in extra-curricular activities, not included in the school curriculum. Therefore, drawing out its curriculum has been left to teachers' discretion. Teachers' beliefs in EE have much more influence on the selection of content of EE than any other psychological factors. It follows that the reality of school EE depends on what teachers believes about EE and which content of EE they select according to their beliefs. This study is to research the realities of the secondary school EE: examine teachers' beliefs about EE and analyse environmental views in their environment-related programs; examine whether teachers' programs reflect their beliefs and environmental views; identify the factors which teachers inhibit teachers from their expression of these beliefs. To identify what perspective was reflected to these programs, this study employs environmentalism. Environmentalism can be classified into 3 categories: environmental management; deep ecology; social ecology. Data were gathered by means of in-depth interviews with five teachers. To show teachers' beliefs clearly, the analysis of the data was conducted on the basis of 5 categories: 'ecological sensitivity', 'value education', 'behaviors', 'issues', 'perception of a cause of environmental problems, related to social structures'. These belifs reflect deep ecological perspective and social ecology. But these perspectives did not accord with those in programs. Most EE programs included only the deep ecological perspective. They didn't reflect their beliefs that students should perceive the cause of environmental problems in the social structure. The factors which teachers find as inhibiting or supporting their expression of these beliefs were analysed as following: (1) EE requests the change of curriculum and methods of instruction; (2) teachers should acquire 'environmental consciousness' and environmentrelated knowledge; (3) programs requests an administrative and financial support.

이 연구에서는 예비과학교사가 계획한 맥락적 NOS 수업을 PCK 관점에서 분석하였다. 서울특별시에 소재한 사범대학에서 교육과정을 모두 이수한 예비과학교사 8명이 연구에 참여하였다. 이들이 작성한 CoRe와 교수학습 지도안을 수집하고 면담을 실시하였다. 분석적 귀납법을 활용하여 수집한 자료를 분석하였다. 연구 결과, 예비교사들이 학습 목표로 선택한 NOS는 수업 주제보다는 NOS를 가르치는 맥락에 따라 다르게 나타났다. 또한 예비교사들은 NOS 학습의 가치를 잘 답변하지 못했다. 모든 예비교사가 학생들이 NOS를 잘 이해하지 못할 것을 우려하였으며, NOS를 과학 내용과 함께 다룬다는 점에서 많은 어려움을 느꼈다. 예비교사들은 학생들이 직접 실험을 하면 오차로 인해 학생들이 NOS를 배우는 데 문제가 생길 것이라고 생각하였다. 한편 예비교사들은 자신의 경험을 근거로 학생들의 NOS에 대한 선개념과 오개념을 추측하였으며, 과학 개념이나 학생의 인지 발달 단계가 NOS 학습에 영향을 미칠 것이라고 생각하기도 했다. 교수 전략 측면에서 NOS를 가르치기 위해 다양한 전략을 사용했음에도 불구하고 NOS를 명시적으로 다루지는 않는 경우가 많았다. 평가전략 측면에서도 수업에서 다루는 NOS를 평가하지 않으려는 모습이 나타났다. 이상의 결과를 바탕으로 예비교사 교육을 위한 시사점을 제안하였다.

이 연구에서는 사례연구를 통해 중등 예비과학교사의 교육과정 설계에서 교육과정 자료의 활용 방식을 조사하였다. 서울 소재 사범대학에 재학 중인 두 명의 예비과학교사가 연구에 참여하였다. 교수학습관에 대한 사전면담을 실시한 후, 교육실습 기간 동안 이루어진 각 예비교사의 수업을 관찰하였고, 모든 교수학습자료를 수집하였으며, 수업 실행 전후에 반구조화된 면담을 진행하였다. 예비교사들의 교육과정 자료의 활용 방식을 읽기, 평가, 응용의 측면에서 체계적으로 분석한 결과, 두 예비교사의 교육과정 설계에서 교육과정 자료의 활용 방식에 상당한 차이가 있었다. 교육과정 자료에 대한 읽기의 방식에 차이가 있었는데, 이는 두 예비교사의 교육과정 재구성에 대한 관점의 차이로부터 비롯되었다. 교육과정 재구성에 대한 관점의 차이는 교육과정 자료의 응용 방식에도 영향을 미쳐서 교육과정 재구성에 대해 적극적인 관점을 지닌 경우 '구성요소 추가'가, 소극적인 관점을 지닌 경우 '구성요소 변형'이 중요한 응용 방식이었다. 또한, 예비교사의 교수학습관에 따라 교육과정 자료를 평가하는 과정에서 학습자를 고려하는 수준에 차이가 있었다. 평가에서의 이러한 차이는 '교사중심활동의 증가'와 '학생중심활동의 증가' 응용에서의 질적인 차이로 연결되었다. 이에 대한 교육적 함의를 논의하였다.

This study investigated how pre-service English teachers perceive the effects of machine teaching on their English writing competence. 35 Korean students who are majoring in English education participated in this study. The participants used machine translators for one of the required courses related to English composition. A survey and focus group interview were conducted at the end of the course. They were asked to answer to what degree they perceive the effects of machine translators on their writing in terms of lexical, sentential, and discourse levels. Furthermore, their perspectives on the effects of machine translation on English teaching including limitations of machine translators, were interviewed in more detail. The results show that the participants perceive machine translators quite positively in terms of improving their writing competence, but they also point out some critical limitations of machine translators. These findings have some pedagogical implications for English writing course instructors, English teacher educators, and program developers.

As a researcher engaged in the mathematical education, mathematics teachers are interested in instructional methods. While it is unlikely that the viewpoints of individual mathematics teachers are reflected in making decisions on instructional purposes and instructional contents, a good many parts of instructional methods on mathematical facts are decided by individual teachers. This means that the role of mathematics teachers is given much weight in the mathematical education. Therefore, the mathematics teachers must not be excluded in all parts of the study of mathematical education. We studied the instructional methods of function concept, a central topic in school mathematics from the following perspectives. First, we examined the characteristics of the three(correspondence-centered, middle, dependence centered) viewpoints about the essence of function concept. And we should that which of them should be the viewpoint of instruction of function concept in school mathematics. Second, we investigated the questions regarding the process of function instruction in school mathematics and presented alternative instruction methods of function concept to solve the questions. Third, we postulated the importance of polynomial function, relating college mathematics in order to present the reason why the polynomial function is importantly treated in functional instruction of school mathematics.

With recent scientific advances and growing interest in AI technologies, AI-based chatbots have been viewed as a practical learning aid for English language development. The purpose of this study is to examine preservice teachers' perceptions on the potential benefits of employing AI chatbots in English instruction and its pedagogical aspects. 28 preservice teachers majoring in English education were asked to use Kuki chatbots for a week with a guidance of a researcher and then report on their perceptions of AI chatbots in terms of perceived usefulness after use, applicability, and educational benefits and drawbacks. Emerging codes and themes were identified and evaluated using Thematic Analysis(TA) based on qualitative data from surveys and interviews. The findings show that six emerging themes were identified, encompassing perspectives on teacher, learner, communication, linguistic, affective, and assessment. The overall findings of this study revealed that AI-based chatbots can play a significant role as learning tools for stimulating interactive communication in a target language. Most preservice primary teachers acknowledge that AI chatbots can be useful as teaching and learning aids for both teachers and students. Furthermore, when applying various learner data to chatbot technology, such as learner assessment and diagnosis, a guided approach is necessary to perform a conversation appropriate for the learner's level and characteristics. Finally, as chatbots have a variety of benefits in terms of affective aspects, they may improve EFL learners' confidence in speaking English and learning motivation.
