This study aims to suggest principles of making example sentences when describing grammar items and examines aspects of example sentences presented in Korean integrated textbooks. The requirements of example sentences in grammar descriptions have been mentioned in several preceding research. However, there is little research which focuses particularly on example sentences in grammar descriptions and examines the appropriacy of example sentences presented in Korean integrated textbooks. Therefore, this study sets up five principles to make appropriate example sentences and examine if these principles are in line with example sentences in Korean integrated textbooks published recently. Comprehension and use of grammar items are two significant aspects when making sentences. Thus, example sentences should show meaning, form and pragmatic information unambiguously. The findings show that most textbooks follow the five principles. However, some example sentences do not meet the requirements to be effective examples. In particular, the integrated textbooks need to include more example sentences related to the topic and the goals of the unit considering the role of grammar.

The purpose of this study was to investigate the effects of training and use of worked-example on chemical problem-solving learning. Schema acquisition and rule automation are the basic components of skilled problem-solving, which are dependent on appropriately focused attention and sufficient cognitive resources. Training and use of worked-example facilitate schema acquisition and rule automation, so improve problem-solving learning. The subjects of this study were 60 high school students. The average age was 17 years old. Then, they were randomly assigned to each groups and the chemical reaction problems used as experimental materials. The independent variables of this study were training and use of worked-examples and dependent variables were time for solution and the number of error. The results of this study were as follows; 1. The worked-example groups spent significantly less time on solution for acquisition problems than the conventional problem groups. 2. The long-acquisition groups spent significantly less time on solution for acquisition problems than the short-acquisition groups. 3. The modified worked-example groups did not spend significantly less time on solution for acquisition problems than the worked-example groups.

A few thermodynamics texts are commonly found to have unrealistic example problems in which the process violates the second law of thermodynamics. This error would result from presentation order in the text which introduces first the first law for cycles, systems, and control volumes and then the second law later. In the presentation order, the example problems deal only with the first law without telling whether the process violates the second law. To correct this erroneous situation, it could be recommended to present the first law and the second law successively so that both laws could be applied simultaneously to the given example problems.

This paper deals with an example of the engineering education through the SE-based development of an underwater-robot kit model. It has a purpose of establishing the example of a SE-based development by undergraduate through executing the requirement and functional analysis, hardware and software design, manufacturing, test and evaluation for developing the model. In addition, it also has a purpose of establishing the basis of the development of an optimized underwater-robot kit through understanding the weight and buoyancy characteristics and the actuation and propulsion characteristics of the developed model.

현재 컴퓨터교육은 컴퓨터의 활용보다는 컴퓨터과학을 통한 창의성 신장 교육으로 비중을 높이고 있다. 이에 따라 창의성 교육의 측면에서 로봇을 활용하는 프로그래밍 교육은 컴퓨터교육 연구의 주요 과제로 떠오르고 있다. 로봇 프로그래밍에 관련된 기존 연구를 살펴보면 주로 로봇 프로그래밍 교육의 효과 및 교육과정 개발에 대한 연구가 주를 이루고 있으며, 점차 구체적인 학습 방법에 대한 연구로 초점이 이동되고 있는 추세이다. 본 연구에서는 로봇프로그래밍 학습 방법으로서 예제의 활용에 주목하고 있다. 예제는 프로그래밍을 가르치고 배우는데 중요한 역할을 하며, 학생과 교사 모두에게 유용한 유형의 학습 자료로 인식된다. 또한, 예제는 학습자가 프로그래밍을 할 때 기본틀, 가이드라인, 힌트 제공의 역할을 수행할 수 있다. 본 연구에서는 로봇 프로그래밍 교육을 위한 NXC 예제를 개발하고, 이를 학습자들이 쉽게 활용할 수 있는 지원 시스템을 개발하였다. 이 지원 시스템은 최근 관심이 집중되고 있는 스마트 교육의 동향에 따라 모바일 웹 애플리케이션으로 개발하였다.

It is undeniable that teachers play the principal roles in education. This is why education and professional development of teachers are so important. Some of recent works have made this fact clearer. In America, in particular, many reports and research papers have recently been published on these problems. In this paper, we first introduce briefly the current system of education, employment, and professional development of mathematics teachers in Korea. And then we mention a research project on education of mathematics teachers. The final report of the project contains some suggestions for curriculums of the department for education of mathematics teachers. We describe one example of extended syllabus which implements those suggestions. The example is on Modern Algebra I.

In this paper, we argue that for general education in engineering, humanistic education is important, thus we propose an illustration of course outline. Recent general education for engineering is focused on only more practical, socially oriented courses, for example, business, law, economics, and entrepreneurship. While these courses are helpful for engineering students, humanistic education is more fundamental for improving the students' capacity for insight, originality and constructing the holistic view. We propose a course "Philosophy of Time and Space" as an example which fit this purpose.

The inverted pendulum is a typical example of unstable systems and has been used for verification of designed control systems. It is also very popular in control education in laboratories, serving as a good example to show the utility of the state space approach to the controller design. This paper shows two kinds of experiment using inverted pendulum: one is the stabilization of a single spherical inverted pendulum by a plane manipulator using visual feedback, and the other is the state transfer control of a double pendulum. In the former experiment, the feedback stabilization using a CCD camera has major importance as an example of controller implementation with non-contact measurement. The latter involves the standard stabilizing regulation method and nonlinear control techniques. The details of the experimental systems, the control algorithms and the experimental results will be given.
