본 연구는 사서교사의 교수역량 즉, 수업전문성을 구성하는 요인을 추출하고, 이를 모형화하는데 목적이 있다. 일반교과교사가 갖추어야 할 교수역량에 관한 문헌은 물론 사서교사의 자격기준 에 관한 문헌을 비교 분석하고, 이를 바탕으로 사서교사의 교수역량 모형을 제안하였다. 본 연구에서 제안한 사서교사의 교수역량 모형은 교수-학습 과정을 고려하여 크게 수업 설계, 수업 실행, 수업 평가로 구분하고, 각 단계마다 단독수업과 협력수업으로 구분하여 제시하였다. 본 연구는 향후 사서교사의 연수 프로그램이나 사서교사 양성 대학의 교육 과정을 개편하는데 기초자료로 활용할 수 있을 것이다.

The purpose of this study is to develop instruction model of environmental problem process focused with environmental justice. This study has analyzed environmental problem solution process in social studies of elementary school from 4th grade to 6th grade with it. The results of this study are as follows. First, social studies of elementary school didn't show distributive justice in environmental problem solving process. Second, procedural justice existed, but offered information is lacking to each main group. Third, substantive justice was emphasized personal viewpoint. We developed instruction model of environmental problem solving process based upon the results. Component of instruction model is problem analysis, distributive justice, procedural justice, substantive justice and evaluating a solution. Timely, teachers can use and can apply it in social studies class. In conclusion, it is strongly recommend to teach environmental education linked with environmental justice. It enables us enhance a new awareness and attitudes towards sustainable development.

The purpose of this study is to develop a Puzzle-Based Computer Science Instruction Model and Learning Program and to confirm the effects. To do so, we selected 2 classes with a similar level of pre-computational thinking in elementary schools in the Jeju Province. After that, from 2 classes, we designated the 5th grade students in 'D' elementary school as group A and designated students of the same grade in 'J' elementary school as group B. In a total of 28 sessions during an 18 week period, a Puzzle-Based Computer Science Learning Program was used with 31 students in group A, and the traditional computer science course was used with 25 students in group B. The results showed that there were significant improvements in computational thinking, which is computational cognition and its creativity, of the students in group A compared to students in group B. Also, this study proved that the Puzzle-Based program correlated with positive changes group A students' Science-Related Affective Domain. In this paper, on the basis of proven effectiveness, we introduce the Puzzle-Based Computer Science Instruction Model and Learning Program as an alternative to traditional, computer science education.

This paper presents a profiling model of a wide-window superscalar microprocessor using multiple branch prediction. The key idea is to apply statistical profiling technique to the superscalar microprocessor with a wide instruction window and a multiple branch predictor. The statistical profiling data are used to obtain a synthetical instruction trace, and the consecutive multiple branch prediction rates are utilized for running trace-driven simulation on the synthesized instruction trace. We describe our design and evaluate it with the SPEC 2000 integer benchmarks. Our performance model can achieve accuracy of 8.5 % on the average.

For development of teaching model for observational experiment and the major contents of science education guide books published for secondary school teacher in America, the actual survey to the secondary schools and the investigation of science education guide were carried out. The results were summarized as follows. 1. The major concepts of contents in science education books are constituted of introduction(9.67%), ability(8.94%), activity(6.61%), curriculum(11.61%), instruction planning(5.25%), instruction strategy(l7.74%), materials and facilities(1O.97%), evaluation(8.62%), society and community(l0.55%), guidelines(4.76%), practice(3.54%), and index(1.74%). 2. The constitution of multimedia teaching model for observational instruction was developed and arranged in order of six steps as observation, materialization, broad understanding, advanced study, application, and synthesis. This model was thought as the most effective for the achievement of the instructive goal for observational unit and others.

This paper presents CARMA (Cycle-Accurate Retargetable Micro-Architecture) as efficient framework for SoC-centric pipelined instruction-set architectures. It is based on ADL (Architecture Description Language) and provides more concise and manifest semantics to describe behavior of instruction set by mixing efficiency of instruction-set simulators and flexibility of RTL simulators. It exploits new timing model method based on process scheduling so it can support general timing model with cycle accuracy for large-scaled architectures usually used in SoC multimedia chip-set. According to experiments, the proposed framework was shown to be 5.5 times faster than HDL and 2.5 times faster than System-C in simulation speed so it is applicable for complex instruction-set pipelined architectures.

This study investigated the effectiveness of the Developmentally Appropriate Instruction Model for Science(DAIM-S) on increasing scientific curiosity and problem solving in young children. Subjects were 60 5-year-old middle class children, randomly assigned to one of two groups: either the DAIM-S group or the direct instruction group. For 2 months, the children in both groups took part in 21 science activity sessions. Both before and after treatment, subjects were tested on curiosity and scientific problem solving. The DAIM-S group showed higher achievement than the direct instruction group in the acquisition of curiosity and scientific problem solving. From these results, the researchers suggest application of the DIAM-S to the science teaching of young children.

This study focused on the developing a system of computer adaptive diagnosis and instruction(CADI). This system is a conceptual model that connected learning with assesment by using new media such as computers, multimedia, and new technologies. In this conceptual model, adaptive diagnosis means tailored or customized diagnostic evaluation, and adaptive instruction implies tailored or customized instruction. The connection between learning and assesment suggests that they are closely related to determine following learning contents and learning methods. CADI's expected effect are 1) it can contribute to real learning of core concept, 2) it can enlarge the educational opportunities, 3) it can help students study by student himself and learn media literacy, 4) information for evaluation functions more essential roles, 5) it is possible to work cooperatively with any other school subject.

The purpose of this paper is to develop a technical writing model suitable for engineering students based on the practice of technical writing using the patent application form for engineering students. The Dick & Carey model was used to design the teaching of technical writing using the patent application form. In particular, the instructor communicates with the learner and instructs the learner to produce and express students' own ideas. Instruction design in technical writing progresses consists of four steps, such as creating ideas by brainstorming, comprising contents, exercising writing, and feedback. Feedback occurs between an instructor and a learner and also does among students. As writing is proceeding step by step, instruction design for technical writing should come forth with specific methods to make students practice writing in work. Following these steps will help engineering school students to make up new products after graduating university.

본 논문은 비동기식 프로세서, A8051의 명령어 레벨 소비 전력 모델을 제안한다. 제안된 소비 전력 모델은 명령어 레벨로 프로세서가 소비하는 전력을 예측하지만, 프로그램이 실행되는 동안 비동기식 파이프라인의 동작 특성을 반영한다. 따라서, 제안된 방법은 프로세서 소비 전력 모델의 복잡도와 시뮬레이션 시간의 증가 없이 비동기식 임베디드 프로세서 소비 전력 모델의 정확도를 효과적으로 향상시켰다. 제안된 소비 전력 모델은 A8051의 소비 전력 특성을 반영하여 구현되었고 게이트 레벨의 합성한 결과를 이용한 소비 전력 예측 결과와 비교하여 성능 평가를 수행하였다. 제안된 소비 전력 모델은 게이트 레벨의 소비 전력예측 결과와 비교하여 94%의 정확도를 보였고, 1,600 배 이상 시뮬레이션 시간을 단축하였다.
