The present study aims to investigate ways in which pre-service secondary mathematics teachers anticipate 1) students' responses to specific mathematical tasks which are chosen or devised by the participating pre-service teachers as requiring students' higher cognitive demand and, 2) their roles as math teachers to scaffold students' mathematical thinking. To achieve the goal, we had our pre-service teachers to engage in an adapted version of Spangler & Hallman-Thrasher(2014)'s Task Dialogue writing activity whose focus was to develop pre-service elementary teachers' ability to orchestrate mathematical discussion. 14 pre-service teachers who were junior at the time enrolled in the Mathematics Teaching Method Course were subjects of the current study. In-depth analysis of both Task Dialogues which pre-service secondary mathematics teachers wrote and audiotapes of the group discussions while they wrote the dialogues suggests the following results: First, the pre-service secondary teachers anticipated how students would approach a task based on their own teaching experiences. Second, they were challenged not only to anticipate more than one correct students' responses but to generate questions for the predicted correct-responses to bring forth students' divergent thinking. Finally, although they were aware that students' knowledge should be the crucial element guiding their decision-making process in teaching, they tended to lower the cognitive demands of tasks by providing students with too much guidance which brought forth the use of procedural knowledge. The study contributes to the field as it provides insights as to what to attend in designing teacher education course whose goal is to provide a foundation for developing pre-service teachers' ability to effectively orchestrate mathematical discussion.

소음진동의 문제해결과 연구개발은 산업현장에서 소음 진동 공학자들이 담당하여할 과제로서 별개의 과제로 양립하는 동시에 상호보완되어야 할 기능도 가지고 있다. 이를 위하여 현장문제는 해결 즉시 해결과정의 정식화 및 해석이 수행되어야 차후 유사한 문제 발생시 수월하게 해결할 수 있는 능력이 배양된다. 제어장치나 해석 S/W는 중공업 분야의 다양한 생산 제품에 적절히 이용하기 위해 기존 도구의 응용보다 자체개발을 지향하여야 한다. 개발과정에서 부수적으로 계측 및 해석기술이 향상되며 축적된 기술은 현장문제 해결시 귀중한 도구가 될 수 있기 때문이다. 이 과정은 마치 처음 단순 해석, 계측 단계에서 실험, 개발로 발전한 후 다시 복잡한 해석, 계측, 실험 및 개발에 이르는 단계적 발전 방향과도 같다고 생각된다.

The purposes of this study were to develop analysis criteria and analyze the two subject competencies of units dealing with the core concept 'Relation' of the middle school Technology-Home Economics textbook in accordance with the 2015 revised curriculum: 'practical-problem-solving-ability' and 'relationship ability'. The subject of analysis of the current study was the activity assignment of Chapter 1 related to the core concept 'Relation', from the twelve middle school 'Technology-Home Economics II' textbooks. The results of this study were as follows: First, some textbooks showed differences in highlighting or downplaying the components of certain subject competencies. The analysis results for 'practical-problem-solving-ability' in textbook A, E, and G were shown in the high frequency, while in textbook D in the lowest frequency. The analysis results for 'relationship ability' in textbook K and A were shown in the high frequency, while in textbook J in the lowest frequency. Second, Value Judgement was the most frequent component of 'practical-problem-solving-ability' followed by Logical Thinking, Practical Reasoning, and Decision-Making. Family Relation and Sense of Community was the component of 'relationship ability' most frequently dealt with followed by Communication, Conflict Management, and Respecting Others, however Environmental and Ecological Awareness was not shown at all. The two subject competencies were mostly reflected in the Technology-Home Economics textbooks from all the twelve publishers.

대부분 학습용 코스웨어는 CD타이틀로 구성되어 전형적인 일대일 학습 형태를 띄고 있어 학습자에게 금방 지루함을 느끼게 하기 쉽다. 또한 인지적 능력이 부족한 초등학생에게 단순한 교과서식의 웹코스웨어를 적용하는 것은 학습 효과를 높이는데 한계가 있다. 본 논문에서는 초등 교육 현장에 웹을 활용하여 아동들의 다양한 협력 활동을 통해 정보를 탐색하고 조사 활동을 할 수 있는 초등학생 수준에 맞는 협력 학습을 위한 웹기반 사이버학습 교재를 개발 적용한다. 이를 활용하여 교과 시간은 물론 일상 생활에서도 주어진 과제 해결에 필요한 정보 자료를 수집, 분류하고, 웹기반에서 토론하여 일반화된 결과를 도출해 내어 문제 해결 능력을 신장시키는 자료를 개발하였다.

The purpose of this study was to analyze the effect of Engineering computer programming instruction using project learning, to find out the ways to solve some revealed problems, and to improve the instruction. Unlike traditional lecture courses, students are encouraged to cultivate problem solving and teamwork skills through the programming project. In order to examine the effect of project learning, a survey was conducted with 49 students. The questionnaire consisted of 20 items with 5-grade scale each, the contents of which included learning value, workload, skills acquirement, assignment and comment. The SPSS, statistical analysis software was used to get statistics such as ANOVA, correlation and mean, etc. The results of this study showed (1) project learning was more efficient to acquire problem solving and teamwork skills compared with lecture learning, (2) there was significant correlation between self directed learning skill and information collecting skill, (3) cyber education system(i-campus) was helpful for students' self learning. But the results also showed that (4) students did not give high scores on items of the workload or difficulty of assignments. So we can conclude that it is necessary to develop the suitable projects for the capability of students to make the better project learning.

The purpose of this study is to analyze inquiry tasks of textbooks in middle schools social studies under the information literacy process and find out teacher librarians' educational information service on the side of information literacy education. Results of the analysis show that middle school students who carry out the inquiry tasks of social studies should select sources, seek its' related information and create their products through writing reports or presentation. Compared with information literacy process of the "Library and Information Skills", the First step of task definition and figuring out information needs and the Third step of representation of information are being implemented. For this reason, teacher librarian could reduce social studies teachers' burden of class and promote students' inquiry activities by teaching skills of suitable materials seeking strategies for solving their task, understanding and synthesizing the information and evaluating their process and result. Therefore, it is necessary to activate collaborative teaching between the teacher librarian and the social studies teacher based on the information literacy.

This study was conducted to compare the self-leadership strategies and locus of control between the problem-solving styles in the Korean engineering college students. Creative problem-solving styles were identified based on the three dimensions. The results of the two-way analysis of variances indicated the main effects of problem-solving styles; each problem-solving style had unique characteristics in relation to self-leadership strategies and locus of control. There were neither main effects of sex nor interaction effects of problem-solving styles and sex. It would be useful to provide the engineering students with the specialized self-leadership training program based on the problem-solving styles.
