This qualitative study investigated two preservice teachers' conceptual ecologies in professional development during the science teacher preparation program. The notion of a conceptual ecology contains nature of knowledge, science and science teaching, learning, and content knowledge and comfort level. The data were collected during the participants' preservice year and their practicum experience. Both data collections and analyzing were from the various sources of interviews, teaching observations, journals, and information and profiles by the participants' supervisor. Two preservice teachers serve as cases representative of this study. Results show that problems preventing the preservice teachers from moving closer to conceptual change teaching were their understandings of the nature of science and the nature of knowledge. The preservice teachers' views about knowledge come from, and what knowledge is, are largely shaped by the nature of science and learning drive pedagogy and classroom practice. Knowledge of and comfort with the subject matter are also important.

This study investigated the effects on young children's vocabulary and reading ability of the comprehensive language-teaching program using web-based picture books. The comprehensive language program was put into operation for 9 weeks with a classroom teacher who had in-service training for this program. The language course for the 23 children in the control group consisted only of ordinary language activities using teacher-made picture cards. Test results analyzed by t-test showed that the 25 children in the experimental group gained more than the control group on reading attitude including the concept of reading, accuracy, verbal expression, participation, contents and originality. Also, the ability to read a fairy tale aloud increased in the experimental group.

Mathematical Problem solving has had the largest focus in the spread of mathematical topics since 1980. In Korea, most of the articles on problem solving appeared 1980s and 1990s, during which there were special concerns on this issue. And there is general acceptance of the idea that the famous statement "Problem solving must be the focus of school mathematics"(NCTM, 1980, p.1) in Agenda for Action, reflected in the curriculum of Korea. In a historical review focusing on the problem solving in the National Curriculum of Mathematics, we can infer that the primary goal of mathematics instruction should be to have students become competence problem solver. However, the practices of mathematics classroom and the trends of research in mathematical problem solving have oriented to ′teaching about problem solving′ and ′teaching for problem solving′. The issue of teaching via problem solving′ remain unsolved in the community of mathematics education and we need much more attention to this issue.

양자화학에는 추상적이거나 비직관적인 개념이 많이 존재하여 학생들이 이해하기에 어려움 을 준다. 다행히, 전통적인 강의실에서의 강의를 보조할 멀티미디어 웹 응용프로그램을 제작할 강력한 도구들이 웹 기술의 발전으로 많이 생겼다. 이 논문에서는 이 문제를 다루는 한 방안으로서 쇽웨이브 기술을 이용하여 웹 브라우저 상에서 쌍방향 시뮬레이션과 시각화를 동시에 해결하는 방법을 제시한 다. 여러 예를 통하여 어떻게 쇽웨이브 기술의 특성을 이용하여 웹에 기반을 둔 학습 자료를 용이하게 개발하는가를 보여준다.

Since the introduction of literature in reading and writing during the 1970s, considerable research has attempted to determine whether literature has significantly positive effects upon enhancement of reading proficiency. It is said that literature extends our knowledge of the world. Through books, we can experience other people's thoughts, experiences, and ideas (Frye, 1964). This paper explored the role of children's literature for the teaching of reading through the literature-based instruction. It focused on why and how children's literature serves as an important context for enhancing learner's reading proficiency of English. It also discussed the authentic use of literature-based strategies for practical classroom use, and suggested the future directions for research toward the literature-based instruction in the domain of reading comprehension.

Recently much research has investigated the role of attention in L2 learning, comparing the effects of explicit learning with those of implicit learning. With this background the research aims at examining the effects explicit focus on form has on L2 learning based on the acquisition of the English article system. The participants were 70 Korean college students who enrolled in English Composition classes. The experimental group received explicit focus on form including grammatical explanation, input enhancement, output practice, and negative evidence (corrective feedback) for two weeks, while the control group was exposed to sufficient input and negative evidence. Completion tasks were administered at the beginning and the end of the semester. In addition, errors in the use of English articles were analysed on their compositions both before and after the different treatments. The analyses of the results show that the explicit focus on form group improved significantly more than the control group, particularly for the definite article 'the', and some changes occurred in the distribution of article errors. These findings suggest that explicit teaching plays a more contributory role than implicit teaching in acquiring L2 knowledge in classroom-based L2 learning.

The reform movements of current mathematics education have based on several major ideas, in order to provide a new vision of the teaching and loaming of mathematics. Of the ideas, the motto of communication of mathematics appears to be a significant factor to change teaching practices in mathematics classroom. Through Vygotsky's sociocultural theory, the psychological background is presented for both supporting the motto and extracting important suggestions of the reform of mathematics education. The development of higher mental functions is explained by internalization, semiotic mediation, and the zone of proximal development. Above all, emphasis is put on the concepts of scaffolding and inter subjectivity related to the zone of proximal development. Seven implications are proposed by Vygotsky's sociocultural theory for the new forms of the teaching and learning of mathematics.

There have been gradually a few studies on Noticing in the domestic and international area. For the purpose of increasing the concern on teacher noticing and pursuing the affluent studies on the noticing, this study tried to explore and understand the background, the meaning, and the properties of the teacher noticing while summing up the views of the various researchers. As a result, the teacher noticing could be defined as a cognitive process which is focused on mathematical objects, students' mathematical thinking, students' emotions, teaching strategies, classroom environment and interprets them to determine how to react. From this, noticing might be cognitive process which is a combined form of the objects and cognitive behavior, while the objects whom teachers notice covers up the mathematical objects and the teaching objects. Eventually, this study expects to serve as a basis to foster the in-depth understanding of teacher noticing and to derive the follow-up studies.

본 연구에서는 중등 전자기 수업에서 사용하는 시각적 표상의 역할에 대한 교사의 인식과 활용 실태를 조사하고 시각적 표상 활용과 관련해서 교사가 겪는 어려움을 파악하고자 하였다. 조사는 온라인 설문 방식으로 진행되었으며 과학교사 121명이 참여하였다. 연구 결과에 따르면, 교사들은 전자기 수업에서 시각적 표상 활용의 중요성에 대해 전반적으로 동의하였으나, 시각적 표상을 주로 과학 지식의 전달 도구로만 인식하는 경향이 있었다. 실제 수업에서 활용하는 방식은 주로 인터넷을 검색을 바탕으로 컴퓨터를 활용해 제시하는 방법을 가장 많이 사용하였다. 구체적으로 전자기 수업에서 널리 활용되는 세 가지 시각적 표상(검전기의 정전기 유도, 전류 주변의 자기장, 전동기의 구조와 원리)에 대해 활용 방식을 조사한 결과, 학생 중심 활용보다 교사 중심 활용이 두 배 가량 많았고, 시각적 표상의 '해석', '구성', '적용', '평가'와 관련해서는 '교사의 구성'이 가장 빈번한 것으로 나타났다. 이러한 교사 중심의 시각적 표상 활용 실태는 시각적 표상의 역할에 대한 교사의 제한적 인식과 밀접하게 연관되어 있는 것으로 보인다. 또한 주어진 세 가지 시각적 표상 활용과 관련된 교사의 어려움은 크게 '교사 자신', '학생', '표상 자체의 특성', '자료 부족이나 수업환경'에 기인한 것으로 범주화되었다. 시각적 표상의 연구와 개발에 있어서 이러한 요인들이 적극 고려되어야 하며 과학 수업에서 시각적 표상을 효과적으로 활용하기 위해서는 시각적 표상의 역할에 대한 교사의 인식이 확장되도록 하고, 교사의 표상 활용 능력을 증진시키는 것이 필요하다.

양태는 화자의 심리적 태도이다. 언어마다 사용된 문장은 양태를 포함한다고 할 수 있다. 전통적으로 양태는 인식양태와 의무양태로 분류할 수 있다. 본 연구는 한국어 양태 이론을 개관하고 이를 토대로 양태의 개념과 하위분류를 선정하였다. 아울러 본격적인 양태 표현의 의미, 기능 대조를 위해 한국어와 중국어의 양태 실현 양상을 밝혔다. 또한, 한국어의 양태 표현 '-(으)ㄹ 수 있다'와 이에 대응되는 중국어의 양태 조동사 '능(能)'을 통사적, 의미적, 화용적 측면에서 대조 분석하고 이를 바탕으로 양태 표현의 효과적인 교수·학습 방안을 마련하는 것을 목적으로 한다. 한국어 양태 표현은 화자의 주관적 태도를 나타내는 문법 요소로서 한국어 교재에서 매우 중요하게 다루고 있으며 많은 문법 항목이 이 양태에 속한다. 한국어의 양태 표현은 유사점이 많고 의미와 기능이 다양하기 때문에 중국인 학습자들이 학습했더라도 사용하기 어려운 문법이다. 따라서 본고는 대조 분석을 통해 중국인 학습자를 위한 효과적인 교수·학습 방안을 제시하고, 이를 활용한 한국어 양태 표현의 실제 교수·학습 모형을 구안하였다. 따라서 한국어 교육에서 양태 표현의 문법 교육 내용을 구성하는 데 도움이 될 것으로 기대한다.
