Although Flipped Classroom(FC) which has recently attracted attention of educational field, showed its various educational effects such as learning academic achievement, attitude, collaborative learning and self-regulated learning. other studies also showed a number of significant problems and challenges in practically implementing. Thus, this study aims to investigate in-service and pre-service teachers awareness of FC in order to explore its educational feasibility for successfully adopting it to classrooms through the alternative solutions to its limitations. To achieve this goal, we firstly conducted literature review on teaching and learning models and guidelines to draw educational prerequisites and then analyzed needs of 156 pre-service teachers and 42 in-service teachers. According to survey results, 80% of teachers are willing to apply FC to their classes and hope to be offered with pre-learning activity materials and guidelines. They consider junior high school students and college students as appropriate learners, social science, science, Korean, and English as suitable subjects, and video content as optimal materials for pre-learning activities.

This study explored secondary mathematics teachers' mathematical knowledge for teaching [MKT]; in particular, it focused on teachers' knowledge of functions. In order to measure teachers' MKT, we developed items according to Ball, Thames & Phelps (2008)'s domains and conducted to 34 secondary mathematics teachers in 5 high schools in Seoul. The findings from the data analysis suggested as follows: a) overall, the teachers scored average 67.4 out of 100, 87.43 in Common Content Knowledge[CCK], and the average score of Specialized Content Knowledge [SCK] was the lowest; b) correlations among SCK, KCS, and KCT were statistically significant; and c) there was no sign of statistical significance between CCK and the rest.

The purpose of this paper was to investigate the difficulties experienced by the novice elementary school teachers in the mathematics classes and suggest some implications for teacher education and effective adaptation of novice teachers. The researchers observed mathematics lessons of 6 novice elementary school teachers and interviewed on the difficulties that they experience in teaching mathematics. The data were collected by lesson observations, interviews, discussion and email communications and categorized the data the types of difficulties those the teachers experience. The difficulties were difference between theory and practice, explanation, questioning, differentiated lesson, application of teaching method, evaluation, and understanding of mathematics. The implication from this study is that novice teachers need to supported by the administration as well as actively participate at various types of educational meetings.

This study qualitatively examined the lives of non-tenured, secondary school teachers who are preparing for the teachers' exam. Semi-structured, face-to-face interviews were conducted with ten teachers and the data were analyzed using the consensual qualitative research method. Most of the participants had chosen a contract-based teaching position, believing that it would meet their financial needs, provide them with the satisfaction of being a teacher and, more importantly, afford practical help with their exam preparation. In practice, however, they suffered from low self-esteem and identity confusion due to discrimination by the school administrators. Ironically, this unfair treatment strengthened the participants' commitment to studying for the exam, in order to acquire a stable and secure position in school. However, they experienced a lot of study-related stress, including a lack of study hours, heavy study load, multiple life roles, physical exhaustion, the difficulties caused by the vague exam guide, and anxiety due to previous failure in the exam. Based on the findings of this study, directions for future research are suggested.

The ADHD, a common condition of childhood onset, is of critical educational and social concern at every level of school. Investigating the determinants of teachers' ADHD coaching and their relative importance is important for improving teaching and counseling practice in inclusive education setting. Based on three hundred and fifty three survey responses from elementary, junior and high school teachers, this research examines the impact of knowledge level, facilitating condition, cooperation with parents, attitude of teachers toward teachers' ADHD coaching. Statistical analysis shows that the knowledge level and facilitating condition influence the level of teachers' attitude, and that attitude has some impact on the cooperation level with parents, at 5% significance level. The cooperation with parent, one of two precedence factors of ADHD coaching, was identified to be significant, but attitude was shown to be nonsignificant predictor of ADHD coaching. A brief discussion concerning the critical needs of teachers is also presented.

Despite evidence that early childhood teachers play a critical role in guiding children through their child assessment, most beginning teachers in the survival stage face the greatest difficulties in this area. Using the intentional and purposeful tools of action research, this collaborative action study supports a beginning teacher in reflecting upon her perceptions of the 'child assessment' of young children and devising and evaluating good guidance practices. During the course of the study, the participating teacher became engaged in more reflective teaching which prompted her to perceive the "child assessment" of the children from different perspectives. As her understanding of the importance of making her curriculum and classroom climate more engaging and meaningful deepened and she reconceptualized her notion of child assessment, the teacher witnessed positive changes in her students' behaviors which, in turn, increased her sense of efficacy. These very positive, empowering results are strong recommendation for using collaborative action research especially in the novice years of teaching for it provides the teacher with a life-long transformative tool for professional development.

One of the most important characteristics in the seventh educational course is an enforcement of differentiated level curriculum. Therefore, development of various different level educational subjects is needed. A new chromatographic experimental kit which is helpful for middle school students to understand chromatographic principles is needed to correct some mistakes of chromatographic part within the 6th educational course's middle school textbook. In this research, a new thin layer chromatography(TLC) experimental kit for middle school students are developed by using acid-base indicator as samples and ethyl alcohol, ethylacetate, hexane as eluents. The kit is applied to two kinds of middle school student groups(general group & genius group) and two kinds of teacher groups(science teacher & non-science teacher) and an efficacy of the new chromatographic kits are evaluated through making up some questions.

본 연구는 중 고등학교 교사 50명에 대하여 기하 문제의 논증기하적 또는 해석기하적 문제해결 전략이 학생들의 평가에 어떤 영향을 미치는가를 조사한 것이다. 중학교에서 고등학교로 진학하면 도형의 문제에 대한 해석기하적인 문제해결 능력은 교육과정 상 대단히 중요하게 가르쳐야 할 내용이다. 유클리드 기하에 바탕을 둔 논증기하의 지식은 좌표평면의 도형을 방정식으로 나타내고 연구하는 해석기하의 기본이다. 그럼에도 불구하고 많은 학생들은 논증기하적 문제해결을 선호하는 반면 해석기하적 문제해결은 어려워한다. 또한 논증기하적 문제 형태에는 논증기하적 문제해결 전략, 해석기하적 문제 형태에는 해석기하적 문제해결 전략을 구사하는 경향을 보인다. 본 연구는 중 고등학교 교사들의 기하 문제에 대한 내용 지식이 학생 평가에 미치는 영향에 초점이 맞추어져 있다.

인터넷의 이용이 생활화되면서 학생들의 인터넷 이용능력은 점차 향상되어가고 있으며 그 이용시간도 증가하는 추세다. 인터넷은 접근하기가 편리하고 시간적, 공간적 제약을 극복할 수 있고, 경제적 이점도 가져다주므로 인터넷의 교육적 활용에 대한 연구가 필요하다. 본 논문은 인터넷에 기반한 교육적 활용의 한 모델로서 WEB기반 학습지도.평가 시스템의 설계 및 구현에 관한 것이다. 즉 가상의 공간에서 교사와 학생이 상호 작용하면서 교수 학습할 수 있는 방법에 주목하여 교사는 WEB상에서 문제를 출제하고 학생 역시 WEB을 통해 손쉽게 문제를 풀고 결과를 확인할 수 있게 하는 것이다. 제안한 시스템의 설계를 위해 기존의 유사시스템을 비교.분석하여 필수 구성요소를 모두 포함하면서 미래의 학습평가방식에 적합한 효율적이고 유연성있는 모델을 만들었다. 설문조사를 통한 평가에서는 시스템의 학습효과성과 발전가능성이 높은 것으로 나타났다. 향후 평가를 통해 나타난 문제점을 보완하고 새로운 기능에 대한 연구가 따른다면 교사와 학생 모두에게 새로운 학습도구로서 흥미를 불러일으킬 수 있고, 학습 도구에 관한 새로운 인식전환의 기회가 될 것으로 생각된다.

이 논문은 중학교 기하 영역의 수업에 대한 학생들의 성취도가 낮은 것을 관찰하고, 그에 대한 고민으로 교육과정을 분석하고, 수학교육의 질적 접근을 위한 교수 실험을 통해 실제 중학교 과정에서 운용되는 논증기하 교육의 문제점과 그 대안을 탐색하고자 하였다. 본 연구에서는 교사가 반드시 갖춰야 할 지식으로 Shulman(1986)이 제시한 교과 내용 지식과 교수학적 내용 지식, 그리고 교육과정 관련 지식을 받아들였으며, 중학교 기하 영역에서 이런 지식을 갖추기 위해 교사가 폭넓은 고민을 하여 수업의 개선점을 찾는 과정을 보여주고 있다. 연구를 통해서 학생들에게 명제를 지도할 때 주의할 점과 학습자에게 증명을 하도록 제시하는 방법상의 문제점, 그리고 이등변삼각형의 지도에서의 그 증명이 갖는 의미를 잘 이해하여 학생들에 증명 학습에 진정한 도움이 될 수 있는 방향을 탐색하였다. 그리고 절차만을 학습시키는 현행 작도 수업을 개선하기 위한 여러 시도와 등변사다리꼴의 학습에서와 같이 학생들이 수학 용어를 되돌아보는 수업이 필요성을 탐색하여, 많은 교수 실험을 통한 교육과정의 바람직한 개정을 제안하였다.
