Logic lays the foundation of Mathematics and the development of Mathematics is dependent on critical thinking. So it is important that school mathematics helps students develop their logical and critical thinking ability for both mathematics learning and problem solving in general. MINDSTORMS, a LEGO based programming activity kit, is an effective teaching and learning tool that can be used to enhance logical and critical thinking in students. This study focused on measuring the growth of students' ability to think logically and critically when they used MINDSTORMS activities to learn programming. In addition, we investigated how the students' logical and critical thinking changed from the MINDSTORMS learning experience. The study confirmed that the programming activities using MINDSTORMS help to enhance logical and critical thinking in students. The students attitude about logical and critical thinking became more positive and the activities helped to engage students to think logically and critically. This type of programming activities should be valuable in mathematics education and it should be included in a general mathematics curriculum.

레고 마인드스톰 NXT는 다른 로봇 키드에 비해서 조작이 간편하며, 고차원적인 로봇 행위를 제어하기 위해 펌웨어인 leJOS를 지원하며, 블루투스를 이용한 원격 제어가 가능하다. 그러나 leJOS는 외부 파일을 제어하거나 센서 하드웨어가 정상 동작하지 않는 등의 몇 가지 문제점이 발견되었다. 본 논문에서는 leJOS가 갖는 이러한 일련의 문제점을 살펴보고, 이에 대한 해결책을 제시한다.

This paper proposes a teaching plan of programming language class for university of education students amusingly with LEGO Mindstorms NXT robot. The goal of class is not fragmentary knowledge acquirement but problem-solving of maze. This robot communicates with GUI named NXT-G installed in computer via USB. GUI is not text-based but icon-based programming tool. This paper designs a semester with 3 steps such as beginner, intermediate, high-rank. Beginner step is consists of learning of basic functions such as GUI usage and several sensors of robot. Intermediate step is consists of solving of maze problem with low complexity. High-rank step is consists of solving maze problem with medium and high complexity. All maze problem-solving have 3 process with algorithm, flowchart, and programming with stack.

프로그래밍 교육은 학생들이 컴퓨터를 주체적이고 능동적으로 활용할 수 있도록 해주며, 창의적 사고력, 수학적 능력 함양등 교육적으로 많은 잠재 가치를 가지고 있다. 그러나 프로그래밍 언어를 학습하기가 쉽지 않고 많은 시간을 필요로 하여 학교 교육에서 소외받고 있는 현실이다. 따라서 본 논문은 개정된 초 중등학교 정보통신기술교육 운영지침의 3, 4단계에서 프로그래밍에 관련된 학습 목표를 추출하여 초등학생에게 적용할 수 있는 학습 내용을 단계적으로 구성하였고, 교육용 로봇인 LEGO MINDSTORMS NXT를 사용하여 학습할 수 있도록 프로그램을 설계하였다.

본 논문에서는 교구용 소형 로봇으로 구현한 군집로봇 시스템을 소개한다. 각 로봇에 내장된 블루투스 무선통신으로 군집로봇 네트워크를 구성하였다. 실험에 사용한 로봇은 $LEGO^{(R)}$ $MINDSTORMS^{(R)}$ NXT이다. 여러 로봇이 라인으로 표현한 대형 미로를 동시에 탐사하는 환경을 가정하였다. 이런 상황에서 각 로봇은 주어진 임무를 수행하면서 센서로 주변 환경 정보를 측정해서 대표 로봇에게 보낸다. 여기에 필요한 메시지 구조를 군집로봇에 적절하도록 설계하였다. 이렇게 군집로봇을 구현하고 실험한 결과, 그룹 대표로봇이 통신을 중계하는 방법으로 통신거리 제약을 해소할 수 있었다.

Compiler course is one of the important courses in computer science. It requires more efficient learning environment because of its large coverage scale and complexity. One of its solutions is to provide the integrated development environment for educational compilers which is enable to give practice-oriented class and enhance student's interest. This paper presents the code generation support system developed in an integrated development environment of educational compiler. Our system helps students to understand the process of code generation and visualizes the relation among the source language, AST, and the target language. It makes students develop their own compilers more easily.

We have been interested in solving escapee-chaser game. In this game, with avoiding chaser, the escapee must escape from given male. The winning strategies of the escapee are driving the chaser to an intended place and closely evading from chaser by using some walls. According to our experience, some stages of the game are too difficult to solve manually. So we take the model checking method to get a solution of the game. Because the model checking with breadth fist search manner exhaustively searches the all state space of the game, the solution using model checking is best solution, shortest path. Fortunately, during the process of finding solution path, the state space explosion problem didn't occur, and the results of the game solving was applied to embedded system, Lego Mindstorm. Two agents, escapee and chaser, were implemented into robots and several experiments conformed the correctness of our solution.
