What constitutes a good mathematics lesson plan? In their teacher education program, preservice teachers (PSTs) are trained for planning mathematics instruction but often have difficulty in evaluating existing lesson plans and creating their own lesson plans. The purpose of this narrative inquiry is to understand PSTs' experiences of evaluating or designing mathematics lessons that they perceive as being good. The narratives of three PSTs who pursue high school mathematics teaching certification will inform us not only of their perceptions of a good mathematics lesson and lesson plan but also their process of finding the one that exists or creating their own.

This study developed and implemented a teaching · learning process plan for Home Economics in middle school by converging Habermas's three systems of action. It also examined the effect of the class through the evaluation of students and teachers who participated in the class. This study developed 10 sessions for a teaching and learning process plan by converging three systems of action and reconstructing learning elements related to 'balanced meal plan' and 'food choice' according to the practical action teaching model. After class, we surveyed the degree of help for students, analyzed the learning activity sheets, and analyzed the reflection journals of teachers to evaluate the effects of the class. This class was found to be the most helpful in practicing the healthy dietary life of students, expanding their thoughts, understanding learning contents, and helping them change their lives. As a result of analyzing the learning activity sheet, students gained enlightenment by reflecting and evaluating their action through the class; in addition, changes in interest, awareness, and action appeared. Through the convergence of three systems of action, teachers who practiced the class criticized and realized the act that students were unconsciously accepted. In addition, it confirmed the possibility that students could change their lives, family and society by promoting optimal nutrition and health for a good life that pursues the best good.

본 고의 목적은 초등학생용 독서자료의 텍스트수준에 영향을 미치는 요인들을 규명하여 텍스트수준 측정 공식을 구성함으로써 텍스트의 수준 평가를 자동화하는 데에 있다. 컴퓨터로 계량화할 수 있는 언어적 요인들을 대상으로 표본집단에 부여된 텍스트수준 점수와의 상관관계를 검토한 결과 글자수, 어절수, 이형어절수, 문장수, 단락수 요인이 텍스트수준을 결정하는 요인으로 드러났다. 단순회귀분석을 통해 도출된 회귀방정식들 중에서 이형어절수 모형이 최적의 공식으로 드러났으나, 중회귀분석을 한 결과 이형어절수요인과 새 어절출현비율요인을 결합한 모형은 설명력이 더욱 향상된 공식으로 밝혀졌다. 공식에 따라 측정된 텍스트수준 점수는 학년 내에서 매우 세분된 단계까지 나타내고 있으므로 각 학생별로 그들의 독서능력에 적합한 자료를 추천할 수 있다.

This study analyzed the quality of mathematics classes with observations using the instrument, MQI(Mathematical Quality of Instruction). Class recordings and interviews were conducted on 2 pre-service teachers and 4 in-service teachers. This study recorded and analyzed 3 or 4 classes for each mathematics teacher by using revised MQI. There were a total of 8 raters: 2 or 3 raters analyzed each class. MQI has four dimensions: Richness of the Mathematics, Working with Students and Mathematic, Errors and Imprecision, Student Participation in Meaning-Making and Reasoning. In the dimension of 'Richness of Mathematics', all teachers had good scores of 'explanations of teacher' but had lower scores of 'linking and connections', 'multiple procedures or solution methods' and 'developing mathematical generalizations.' In the dimension of 'Working with Students and Mathematics', two in-service teachers who have worked and having more experience had higher scores than others. In the dimension of 'Errors and Imprecision', all teachers had high scores. In the dimension of 'Student Participation in Meaning-Making and Reasoning', two pre-service teachers had contrast and also two in-service teachers who hadn't worked not long had contrast. Implications were deducted from finding to improving quality of mathematics classes.

도덕과수업은 내용의 이해, 이해의 적용, 적용의 반성이라는 일반적 순서로 전개된다. 수업의 첫 단계인 내용의 이해는 주로 추상적인 도덕적 개념의 이해와 관련된다. 추상적인 도덕적 개념의 이해에 적용될 수 있는 수업모형이 개념분석모형이다. 이 개념분석모형의 이론적 배경은 윌슨의 '개념분석법'에서 찾을 수 있다. 윌슨의 개념분석법은 일상언어의 비형식논리에 근거하여 개념을 분석하는 사고의 기술이다. 이 기술은 개념적 질문을 분리하기, 정답찾기, 전형적 사례 찾기, 반대 사례 찾기, 관련 사례 찾기, 경계 사례 찾기, 가상 사례 찾기, 사회적 맥락 검토하기, 이면의 불안감 검토하기, 현실적 결과 검토하기, 언어적 결과 검토하기로 구성된다. 이러한 기술은 분석할 개념 찾기, 개념 이해를 위한 사례 찾기, 개념 사용의 맥락 검토, 설정된 개념의 타당성 검토의 단계로 적용될 수 있다. 그러나 이러한 개념분석의 기술과 단계의 명칭을 초등학교 학생들이 이해하기는 어렵다. 초등학교 수준에게 분석의 기술과 단계를 적용하기 위해서는 학생들이 이해할 수 있는 용어로 번역하여 제시해야 한다. 또한 학생들이 흥미롭게 탐구할 수 있는 양식으로 제시해야 한다. 본고에서는 개념분석의 기술을 초등학생들이 이해할 수 있는 활동의 명칭으로 바꾸고, 이를 '정직' 개념의 이해를 위한 수업에 반영하는 방안을 제시한다.

Turbo codes are extensively used in current communications standards and have a promising outlook for future generations. The advantages of software defined radio, especially dynamic reconfiguration, make it very attractive in this multi-standard scenario. However, the complex and power consuming implementation of the maximum a posteriori (MAP) algorithm, employed by turbo decoders, sets hurdles to this goal. This work introduces an ASIP architecture for the MAP algorithm, based on a dual-clustered VLIW processor. It displays the good performance of application specific designs along with the versatility of processors, which makes it compliant with leading edge standards. The machine deals with multi-operand instructions in an innovative way, the fetching and assertion of data is serialized and the addressing is automatized and transparent for the programmer. The performance-area trade-off of the proposed architecture achieves a throughput of 8 cycles per symbol with very low power dissipation.

This paper compares and contrasts the perspectives of effective mathematics teaching by 135 elementary school teachers, 132 middle school teachers, and 124 high school teachers using a questionnaire in South Korea. All groups of teachers chose in common the teaching and learning strand as the most important for effective mathematics instruction. However, elementary school teachers placed greater importance on the curriculum and content strand than their counterparts did. Elementary school teachers tended to agree more upon the 48 items related to good mathematics teaching than their counterparts did. The similarities and differences among the groups of teachers are expected to provoke discussion of what constitutes high-quality mathematics instruction and how such perspectives may be situated in the socio-cultural context.

The purpose of this study is to help the students in middle school improve their English listening comprehension by presenting effective teaching and learning techniques using animation. A good animation provides a self-contained world with language expressed in a virtual context. A few animation such as "Mulan", "The Emperor's New Clothes", and "Gulliver's Travel" are presented. The materials are primarily for English listening comprehension, enhance awareness of American culture and life-styles, and to encourage students' active role in learning English. It is suggested that their use with content-based instruction, where animation provides relevant schema background, makes language relevant and comprehensible. Practical aspects of classroom instruction are discussed, focusing on the adaption of pre-viewing, while-viewing, and post-viewing activities to the selected animation. It is concluded that careful animation selection, purposeful lesson planning, and the integration of pre-viewing, while-viewing, and post-viewing activities into the content-based lesson encourage natural language skills, especially the listening comprehension and students' interest in English.
