The purpose of this study is to identify stepfamily adolescents' emotions related with parental remarriage and the need for education program for them. Forty three stepfamily adolescents in middle and high schools in Seoul were surveyed. As a main result, the most of stepfamily adolescents felt a difficulty in adjustment to stepparent even through more than half of the adolescents perceived the advantage of parental remarriage. The greatest number of stepfamily adolescents wanted an understanding of themselves from parents and agreed the necessity of the educational program for them. 'The understanding of stepfamily', 'The resolution of conflict with stepparent' and 'Stress management' were the popular topics which were demanded as program contents by stepfamily adolescents. Several discussions and conclusions on the main result were suggested.

The most of elementary school science textbook contents are composed of observation and experiment activities. When students study natural phenomena, observation and experiment are st rongly emphasized to improve understanding of scientific concepts and inquiry abilities. The purpose of this study is deep understanding about experimental science classes. This ethnographic study is conducted by observations of experimental science classes in natural setting and interviews of teachers, students of the 5th grade. The conclusions of this study are as follows: First, the general process of the elementary science experimental classes is 'identifying learning purposes -1 planning experiments -1 predicting the results -1 experimenting-t summarizing the results.' The experiments are conducted by group activities and the teachers conceived that the me st difficult step considered by students is 'planning experiments'. Second, students like hands-on activities, but they feel difficulty on less guided experiments. Students perform results oriented-activities. Third, in group activities, students prefer to work with the same gender or collaborative peers.

Two groups of students, who are the students in the natural science course of high school in Korea, learned the equation of figure in space (point, line, plane) to understand more effectively with two different textbooks. One group was taught with the textbook used now in most high schools and the other group was taught with the textbooks systematized by associating old concept with new concept. The results are as follows : 1) We need understand the basic concept of vector plainly and flexibly to apply it to the solution of problems. 2) It helps students understand new concepts how we should establish the concept about point, line and plane in space by applying the concept about those on XY plane, 3) It is very effective in understanding the new knowledge system more easily to analyze the existent concepts and to arrange them systematically for efficient understanding of new concepts. 4) The texts which consist of contents organized by basic concepts improve students' learning ability.

The concern with scientific mode1s has been growing in science education, and schematic models are frequently used to teach science concepts in secondary schools. The aim of this study is to investigate how well the scientifically gifted students understand scientific concepts through activities of modifying scientific models which we developed. Thirty 8th-grade students participated in the study, 15 in a control group and 15 in an experimental group. For the students in the experimental group, teaching material with activities of modifying models, while for the students in the control group, the teaching material with traditional activities such as explanation, problem solving, and reading. The teaching contents in physics for both groups were linear momentum. We used multiple-choice test and essay-type test to evaluate students' achievements after lessons, and then compared their achievements of both groups. Through the research, we could find a clue that model-modifying activities are helpful for the gifted students to enhance their understanding of physics concepts, although the statistics does not show meaningful difference between experimental and control groups.

수학 학습에서 수학 용어의 의미를 이해하는 것은 그것과 관련된 학습 내용을 이해하고 활용하는데 중요한 역할을 한다. 수학 용어의 의미를 잘 이해하기 위해서는 용어를 학생의 이해 수준과 언어 능력에 맞도록 적절하게 제시하여 일관성 있게 사용하고 표현하는 것이 필요하다. 본 연구에서는 초등학교 수학 교과서에 나타난 용어의 의미를 서술하여 사용하는 방식과 표현이 부적절한 사례를 수학적 관점과 일관성 관점에서 고찰하여 용어 사용과 표현의 적절성에 대한 시사점을 얻고자 한다.

Recently, there are studies the argument that arithmetic rules established by the four fundamental arithmetic operations, in other words, commutative laws, associative laws, distributive laws, should be explicitly described in mathematics textbooks and the curriculum. These rules are currently implicitly presented or omitted from textbooks, but they contain important principles that foster mathematical thinking. This study aims to evaluate the current level of understanding of these computation rules and provide implications for the curriculum and textbook writing. To this end, the correct answer ratio of the five arithmetic rules for 1-4 grades 398 in five elementary schools was investigated and the type of error was analyzed and presented, and the subject to learn these rules and the points to be noted in teaching and learning were also presented. These results will help to clarify the achievement criteria and learning contents of the calculation rules, which were implicitly presented in existing national textbooks, in a new 2022 revised curriculum.

The Purpose of this study is to examine the present marine science education programs in Korea and understand how they are organized and how well they are being used. Eventually, being a foothold research prior to the construction of an inclusive marine science education portal site for elementary, middle, and high school students is the objective of this study. Through this study, we can expect three positive effects. First, through classification of marine science education programs, it can be used when dividing the contents and writing textbooks for elementary school students. Second, through the construction of portal site, we can expect to correct the recognition and understanding of marine and it will contribute to the future industry development. Third, we can offer the correct materials for teaching and learning and through learning, understanding on marine will get better.

현재 중학교에서는 덧셈에 대한 곱셈의 분배법칙을 문자변수를 사용하여 일반화의 맥락에서 정의하여 도입한다. 그런데 분배법칙에 대한 학생들의 이해도는 높지 않다. 일반화의 맥락에서 도입되는 분배법칙을 의미 있게 학습하려면 특수한 맥락에서 분배법칙의 풍부한 이해가 선행되어야 하므로, 본 연구는 한국과 일본의 초등학교 교과서에서 다루어지는 분배법칙 내용의 비교 분석을 통해 교육적 시사점을 도출하고자 한다.

This study aimed at identifying the organization of contents, the level and scope, the time of study and experiment acivities in science text books by comparing and analizing the characteristics of the Elementary School Educational Curriculum in Korea, China and Japan. First, the objectives of science subject are focussed on understanding nature exactly, learning inquiry methods and developping scientific attitudes. This is very desirable in the lights of teaching students' characteristics. Second, three countries, Korea, China and japan treat the natural phenomena impartially in the formation of the contents of natural science. Especially, china threats scientic contents related to the real life themes importantly. Third, the number of concepts and pages of the natural science textbook are put in Korea. China and Japan in order. Time of study and the level scope of contents in natural science should be composed of desirable national situations. Forth, the time of experiment activities is put in Korea, Japan and china also in order.
