The purpose of this study is to develop and apply the algorithm teaching materials centered on plays(ATMCP) to improve problem-solving abilities of elementary students. For this goal, the ATMCP were reviewed by the expert group and tested them out on 71 fifth-grade elementary students in Daegu, Korea during the 6 weeks. We divided students into two groups: one is the group of the ATMCP and the other is the group of conventional algorithm teaching materials(ATM). And we analyzed the change of the problem-solving ability of each group between before and after using two types of teaching materials with the Mixed ANOVA. The result showed that there was a significant difference in students' problem-solving abilities between before and after using them and the group of the ATMCP was greater improvement than the group of the conventional ATM in a problem-solving ability.

한국정보올림피아드 경시대회 초등부 전국대회를 준비하는 학생들을 위해 본 교재를 개발하고자 한다. 본 교재는 J.S.Bruner의 표상이론에 맞게 알고리즘의 진행 절차를 시각화하여 이해가 쉽고 빠르게 되도록 구성하였으며 이를 실제 코드로 작성하여 자신의 논리를 프로그래밍 언어로 표현할 수 있게 하였다. 또한 기출문제, 확인문제 등을 통하여 배운 알고리즘을 확실하게 익혔는지 확인한다. 이러한 교재 개발이 경시대회를 준비하는 초등학생들에게 관련 도서가 전무하여 기회를 놓치버리는 일 등이나 사교육비를 들여 학원에만 의존해야 하는 최근의 경향에 대한 대안으로 사용되기 바란다.

The core of programming learning is based on an algorithm learning and the promotion of problem solving abilities is the purpose of this learning. Then, we need to think about what kind of algorithms in what order we teach and we need to study the effect of this learning. The purpose of this study is development and implementation of algorithm instructional materials and examine the effect of an algorithm learning with conceptual algorithms in KOI(Korea Olympiad in Informatics) final test of elementary students.

In order to analyze the change of student's logical thinking, in this study, we were develop the educational materials. This educational materials were used in algorithm class through educational programming language Scratch. Algorithms of education materials were selected by analysis of foreign ACM and domestic middle school curriculum. The developed educational materials were applied to 4th grade students of elementary school. In order to analyze the change of student's logical thinking, we were used GALT short version. Total logic and Combinational reasoning, in the experimental group students, were growing significantly.

With a focus on LabView language to program Lego Mindstoms Robot in afterschool class to help children develop their special ability and aptitude. The purpose of this research was to make proposal for programming learning method using a robot as an algorithm learning tool to improve creative problem solving ability. To do this, robot programming training program in the amount of 30th period and teaching aids thereof were developed, and 6th grade primary school children were taught up to 30th period, then after, they were evaluated accordingly. Results from analysis of evaluation of achievement level with a focus on outcomes according to each period revealed that learners understood most of contents of curriculum. In view of such results from evaluation, it is judged that the curriculum as well as teaching aids that devised and created have been constituted in order that school children will be able to have developed a shared understanding of their learning sufficiently, and to put it into practice easily. Through these hands-on experiences in the course of researches, researcher could have confirmed the possibility of success for robot-programming training class as new creative algorithm learning tool in the primary school curriculum.

It is possible to solve many structural problems such as the occurrence of a lot of errors involving misspelling which may occur during the learning of existing programming language, difficulty in grammatical expression and understanding, and difficulty in the expression of algorithm if the program learning tool of the department of computer education in a college of education is utilized as an educational robot. This study developed a learning model (curriculum and a textbook) so that students who major in computer education may easily learn programming by using the NXT software of a Mindstorms robot.

In this study, we analyzed algorithm curriculum in Korea, the United Kingdom, the United States, India, and Estonia. In order to teach 1st - 9th grade students computer algorithm, we suggested the algorithm framework based on the spiral curriculum, which is repeatable and progressive. The framework is divided into 4 areas, which includes understanding, expressing, evaluating, and using algorithms in daily life. Each area has 4 levels which are based on the students grade. We have to offer lectures for about computer OS to student teachers at the National Universities of Education; to develop textbooks and materials about algorithm; and to establish Information Science as a part of the primary school curriculum.

Algorithm education is emphasized as an instrument for teaching the basic principles of Computer Science. But these materials is very short-fall. We'll present the CS Unplugged-based algorithm contents, which is easy to learn for elementary student. These contents for self-directed learning consisted of the activity-based learning. For problem-solving algorithm learning in everyday life we were developed the hashing techniques on the basis of the basic searching and sorting algorithms. For checking the adequacy of these materials were tested by surveys of teacher professional groups, and we obtain the appropriate conclusions for sorting algorithm contents for improving the problem-solving ability for in elementary student.

The importance of algorithm education has been emphasized for creative problem-solving capability. Especially, algorithm teaching materials related with mathematics and science are under development to enhance logical thinking. However, there are not enough teaching-learning models applicable in the field of education. Therefore, this paper proposed a teaching-learning model for effective algorithm education. The teaching-learning model reflects two characteristics : an algorithm learning process is spiral, and algorithm education is based on logical thinking. Furthermore, a survey was conducted for students' satisfaction, and the result was a mixed teaching-learning model with PBL, SDL, and peer tutoring. Based on the proposed model, examples of classes for mathematics and science are suggested to show the feasibility of effective algorithm education.
