본 연구는 유아교사의 동료장학과 교사발달을 위한 동료 평가 척도개발을 목적으로 실시되었다. 선행연구에서 유아교사 평가척도에 대한 연구는 많이 논의되어 왔으나, 평가자는 주로 원장 또는 상급자에 의해 일시적인 평가나 자기평가로 이뤄져왔다. 본 연구에서는 주변 동료교사를 통해 유아교사 평가가 이뤄질 수 있도록 문항을 개발하였다. 동료교사를 통한 평가는 교사의 지속적인 모습을 평가할 수 있기 때문에 교사에 대해 보다 세밀하게 평가가 이뤄질 수 있다는 점에서 장점이 있다고 볼 수 있다. 본 논문에서는 51개 문항을 가지고 동료 평가를 실시하였는데, 9개 영역으로 분리하여 150명을 대상으로 설문조사를 실시하였다. 이를 위해 척도의 적절성(내용타당도, 구인타당도, 문항내적합치도)과 문항의 적절성(문항변별도)을 분석하였다. 분석 결과 동료 유아교사 평가 문항으로서 적절한 척도임을 알 수 있었다.

In this study, I investigated how pre-service teachers (PSTs) proved three geometric problems by using Geometer's SketchPad (GSP) software. Based on observations in class and results from a test of geometric reasoning, eight PSTs were sorted into four of the five van Hiele levels of geometric reasoning, which were then used to predict the PSTs' levels of reasoning on three tasks involving proofs using GSP. Findings suggested that the ways the PSTs justified their geometric reasoning across the three questions demonstrated their different uses of GSP depending on their van Hiele levels. These findings also led to the insight that the notion of "proof" had somewhat different meanings for students at different van Hiele levels of thought. Implications for the effective integration of technology into pre-service teacher education programs are discussed.

The purpose of this study was to investigate what elementary teachers know about students' science misconceptions and how the teachers plan for and address their students' misconceptions in instruction. The sample included 61 teachers who participated in a teacher training program irrelative to science education. A questionnaire into which Gomez-Zwiep's semi-structured interview questions was transformed was used to examine the teachers' understandings of definition, origin, examples, and so on of science misconceptions, and their instructional strategies for addressing their students' misconceptions before and while instruction. The results showed that many teachers (about 60%) did not have appropriate understanding of students' misconceptions, that the majority of the teachers (about 75%) did not consider misconceptions at all before teaching science lessons, and that almost all the teachers (about 90%) did not know particular strategies specifically designed for misconceptions.

The purpose of this ethnographic study was to observe and understand interactions of toddlers and teachers in context. Specific questions were "What are the motives and features of the interactions between toddlers and teacher?" Subjects were twenty 2-year-old daycare children and their teachers. Methods covered 11 weeks of interviews and participatory observation. The major findings were that the interactions between toddlers and teachers was mainly initiated by toddlers and consist of physiological and emotional needs, conflict mediation and participation in play. As toddler get to the age of self-recognition but still need adult's assistance, the co-existence of dependence and independence was evident. Children used a variety of verbal and non-verbal signals with both positive and non-positive overtons.

This study examined the perception of teachers and students on the practice of elementary science class. For this study, an examination tool was made by extracting characteristics of good science class through precedent study investigation and revising it in a questionnaire form of a Likert scale, and conducted to 194 elementary teachers and 320 elementary students. As a result of the study, teachers generally perceived science class positively and teachers with career more than 6 years thought it more positively than them with career less than 5 years. Consequently students have a substantially positive perception level about the practice of the elementary science class, and students of 3th and 4th grade perceived science class positively than 5th and 6th grade in all domains. Finally when analyzing perception difference between teachers and students about the practice of the elementary science class, it appeared that students perceived science class more positively than teachers in most questions.

The purpose of this study is to investigate the optimal conditions for designing tasks appropriate to the elementary classroom based on the correspondence with the national curriculum, integration among four skills (listening, speaking, reading, and writing), authenticity, and interactivity. For this study, two primary English teachers volunteered to participate in the case study conducted in the spring semester of the 2012 school year. Each class observed was composed of 29 and 30 sixth graders (12-year-old learners). Data were collected through classroom observation and lesson plans. Optimality theory was used to analyze data from the lessons. From the findings, the overall ranking of constraints is Curriculum ${\gg}$ Integration ${\gg}$ Authenticity ${\gg}$ Interactivity. It is also shown that for teacher 'L', the tasks such as 'guessing game', 'photo of me', and 'role play' were appropriate to help students ask questions and give reasons for their choices. As for teacher 'C', the tasks such as 'hand spans', 'transport survey', and 'picture telling' needed to be considered in order to help students understand and write comparative sentences.

In this research, we interviewed primary school teachers and students with hypothetical situations questions and got a comprehensive picture of the status quo of what is happening in the new mathematics classrooms of Mainland China, that is, teachers' conceptions of mathematics and their teaching approaches influence the students' conceptions of mathematics to a large extent. For the teacher who emphasizes the precision and rigidity of mathematics, her students focus on the superficial characteristics of mathematics. On the contrary, for the teacher who believes that mathematics is an open process, related to real life and rich in content, her students are more interested in mathematics and have more diverse conceptions.

A debate about the importance of geometry courses has existed for years. The questions have revolved around its significance to students and teachers alike. This study looks to determine whether a teacher taking a college-level geometry course has a positive relationship with their students' algebraic reasoning skills. Using data from the High School Longitudinal Study 2009 (HSLS09: Ingels et al., 2011, 2014), it was determined that 9th-grade teachers who took a college-level geometry course had a significant positive association with their students' 11th-grade algebraic reasoning scores. This study suggests that teachers who take geometry during college have a lasting effect on their students. The implications of these findings and how they may affect higher education are discussed.

본 연구는 교육과정 평가원이 제시한 수학과 교과 내용학 평가 영역 및 평가 내용 요소에 따라 2009학년도부터 2012학년도까지, 중등교사 임용시험에서 출제된 수학과 교과 내용학의 문항을 분석한 것이다. 연구의 목적을 달성하기 위해 4년간 출제된 수학과 교과내용학의 105 문항을 수집하여, 9개 과목 간, 평가 영역 및 평가 내용 요소에 따라 출제된 비율을 분석하였고, 그 결과를 토대로 사범대학 수학교육과 교육과정의 운영이나 평가영역의 재조정에 대한 시사점을 도출하였다. 연구 결과 수학과 내용학의 9과목 간 출제비중에 있어서 현저한 차이가 있으며, 과목별 평가 영역 간에도 출제 비중에 있어서 큰차이가 있는 것으로 나타났다. 평가 내용 요소의 분석에 있어서도 262개 중에서 153개가 4년동안 교사 임용시험에 출제되지 않은 것으로 나타났다. 이러한 분석 결과에 근거하여 수학과 내용학의 출제 과목간의 비중이나 평가 영역 및 평가 내용 요소의 재 조정에 대한 필요성을 논의하였다.

This study identified concepts of heat and temperature. The study was conducted by 200 pre-service elementary school teachers at J-university. The questionnaire consisted of 11 multiple choice questions regarding equilibrium of heat, amount of heat, conduction, and radiation. The questions were designed to provide reasons based on answers. The results showed a misconception about the direction of heat transfer. A large percentage of individuals surveyed believed temperature was a measure of heat and also thought heat to be an element. They were not able to distinguish between conceptions of heat and conceptions of temperature.
