The purpose of this paper is to present a specific set of home teaching methods in hopes to prevent slow learner of the elementary mathematics. This paper deals with the number and operations, one of five topics in the elementary mathematics A survey of two hundred elementary school teachers was made to see the teacher's opinions of the role of home studying and to concretize the contents of the research topics. There were asked which is the most essential contents for the concrete loaming and which is the most difficult monad that might cause slow leaner. And those were found to be; counting, and arithmetic operations(addition and subtraction) of one or two-digit numbers and multiplication and their concepts representations and operations(addition and subtraction) of fractions. The home teaching methods are based on the situated learning about problem solving in real life situations and on the active teaming which induces children's participation in the process of teaching and learning. Those activities in teaching each contents are designed to deal with real objects and situations. Most teaching methods are presented in the order of school curriculum. To teach the concepts of numbers and the place value, useful activities using manipulative materials (Base ten blocks, Unifix, etc.) or real objects are also proposed. Natural number's operations such as addition, subtraction and multiplication are subdivided into small steps depending upon current curriculum, then for understanding of operational meaning and generalization, games and activities related to the calculation of changes are suggested. For fractions, this paper suggest 10 learning steps, say equivalent partition, fractional pattern, fractional size, relationship between the mixed fractions and the improper fraction, identifying fractions on the number line, 1 as a unit, discrete view point of fractions, comparison of fractional sizes, addition and subtraction, quantitative concepts. This research basically centers on the informal activities of kids under the real-life situation because such experiences are believed to be useful to prevent slow learner. All activities and learnings in this paper assume children's active participation and we believe that such active and informal learning would be more effective for learning transfer and generalization.

The purpose of this research is to minimize the learning deficiency on science subject in changeover from the 7th education curriculum to the next curriculum which was noticed in 2007. We investigated the contents overlapped or omitted in science contents organization between the two curriculums; moved contents to upper or lower grade, deleted contents, enlarged contents and reduced contents. Also we found that the deficiency will be occurred for the students who entered school in 2006 and 2007 in elementary school. To minimize the learning deficiency in the changeover, we must consider the following points. (1) We need to promote the teachers' comprehension about the learning deficiency and supplementary instruction through the teacher training program before carrying out the next curriculum. (2) We must add the measures minimizing the learning deficiency to the teachers' guide and resources which are used in encouragement of learning and teachers' training. (3) We must develop the instructing materials to supplement the learning deficiency for the students who entered school in 2006 and 2007. As practicing above points, we will be able to reduce time loss in studying and teaching the same contents and to supplement the omitted contents.

This study is to establish the domains and the standards of instructional evaluation on the teacher knowledge dealing with the knowledge of 'teaching and learning methods and assessment'. Especially, in this study, the instruction assessment standards are developed focused on the five types of mathematics competencies such as problem solving, communication, reasoning, connection, information and handling, which were emphasized in the mathematical curriculum revised in 2022. By the result, ten domains such as an instruction involving instruction goal and content, problem-solving competency, data treatment competency, learners' achievement level and attitude, communication competency, reasoning competency, connection competency, the assessment method and procedure based on the competency, the assessment tool development based on the competency, assessment result based on the competency were new established. According to those domains, the total 20 instructional evaluation standards were developed. This study is limited to consider the domain of 'teaching and learning methods and assessment' among the domains of teacher knowledge, while dealing with the elements of mathematics competencies in the standards. However, instructional evaluation standards reflecting these competencies should be developed in the other diverse domains of teacher knowledge.

최근 개발 적용되고 있는 국내외 교육과정에서는 지식정보화 사회의 구성원으로서 학생들이 습득해야 할 핵심 소양으로 '문제해결' 역량이 강조되고 있으며, 문제해결력 향상을 목표로 한 프로그래밍 교육 방안이 다양하게 연구되고 있다. 하지만 관련 연구에서 다루어지고 있는 프로그래밍 문제는 전통적인 프로그래밍 수업에서 활용되고 있는 문제와 차별성이 없었으며, 제시된 문제를 다루는 방법의 대부분은 문제해결 능력 제고에 적합하기 보다는 특정 프로그래밍 언어를 습득하는데 주안점을 두고 있었다. 이에 본 연구에서는 문제해결 역량 함양에 적합한 프로그래밍 문제와 교육과정을 개발하고 문제해결활동(PSA)을 중심으로 교수 학습 콘텐츠를 설계 개발하였다. 또한 개발된 콘텐츠를 교재로 교육과정을 운영하여 학습자의 문제해결력과 논리적 사고력 향상에 유의미한 결과를 얻었다. 본 연구 결과는 '문제해결' 역량 증진을 목적으로 프로그래밍 교수 학습 콘텐츠나 교육과정을 개발 운영할 때 기초 자료로나 참조 모델로 활용될 수 있을 것으로 기대된다.
