The purpose of this study is to find oui the effects of teaching mathematical concepts by designing and applying teaching and learning programs that takes into consideration the students' strong intelligence, through the teaching and learning strategies based on the multiple intelligences theory. For this study, developmental and experimental research was conducted. In the developmental research part of the study, teaching and learning programs for teaching the concept of multiplication were designed and the activities based on the multiple intelligences were chosen. On the other hand, in the experimental research part, the data acquired from the application of nonequivalent control group pretest-posttest design in the actual classes was processed and analyzed. The results above indicate that the teaching and learning program based on the multiple intelligences theory improved the students' overall understanding of mathematical concepts by providing various types of activities. In addition, this program helped students to increase their confidence and generate a positive attitude towards learning math.

Polishing a die that has free-form surfaces is a time-consuming and tedious job, and requires a considerable amount of high-precision skill. In order to reduce the polishing time and cope with the shortage of skilled workers, an automatic polishing robot system was developed. The polishing robot system is composed of two subsystems, a three-axis machining center and a two-axis polishing head. The machining center is controlled by a FANUC controller, and the polishing head by DSP controller. The system has five degrees of freedom and is able to keep the polishing tool normal to the die surface during operation. To easily operate the developed polishing robot system, this study developed an integrated operating program in the Windows environment. The program consists of five modules: a polishing data generation module, a code separation module, a polishing module, a graphic simulator module, and a teaching module. And, the automatic teaching system was developed to easily obtain teaching data and it consists of a three dimensional joystick and a proximity sensor. Also, to evaluate the performance of the integrated operating program and the polishing robot system, polishing experiments of a die of shadow mask were carried out.

급변하는 사회 환경에 따라 학교교육도 다양성을 추구하고 있는 가운데 교실 내에서도 획일적인 수업이 아니라 학생의 수준에 따라 교육과정을 편성하여 운영하도록 요구되는 추세이다. 이에 본 연구에서는 초등학교 6학년 학급 내 기존의 수업방법에서 탈피하고, 개정 제7차 수학과 교육과정에서 강조하고 있는 수준별 수업을 현장에 적용하기 위해 실험집단을 상, 하 집단으로 편성하여 각 집단에 맞는 수준별 수업 프로그램을 구안하여 적용한 후, 수학 학업성취도 및 수학적 성향에 어떠한 영향을 미치는지 알아보았다. 이 연구는 개정 제7차 수학과 교육과정이 추구하는 목적을 사전에 적용하여 분석해 봄으로써 교실에서 수준별 수업의 방향을 제시하고자 한다.

This study intended to find evidence of changes in teacher beliefs of teaching and learning and a case of infusing research experiences in teaching modules since their research participation. As part of this study, twenty three science and math teachers in Korea were provided with science research labs and field experiences in the University of Iowa for three weeks. The research units that teachers participated in for three weeks covered seven fields of subjects such as: geology, astronomy, chemistry, physics, mathematics, computer science, and environmental engineering. In the course of this study, the effectiveness of science research participation program was explored in terms of changing teacher beliefs and their production of teaching modules based on their research. This study especially focused on identifying changes of beliefs on science teaching and learning after participating in the research. A case study of a participant teacher was also conducted by comparing descriptively teaching modules before and after experiencing the program. It was found that the program affected the new modules and the research experiences affected participants' beliefs toward student centeredness.

본 연구에서는 김성원과 이영준(2019)의 프로그래밍 기반 TPACK 교육 프로그램이 예비 교사의 수업 전문성에 미치는 효과를 분석하였다. 연구 대상은 40명의 예비 교사이며, 두 집단으로 나누어 처치를 진행하였다. 실험 집단(n=20)에게는 프로그래밍 기반 TPACK 교육 프로그램을 처치하고, 통제 집단(n=20)에게는 ICT 도구 기반 TPACK 교육 프로그램을 적용하였다. 예비 교사의 수업 전문성 변화를 분석하기 위하여 수업 전문성, 교수 효능감, 테크놀로지 통합 자아효능감을 측정하는 검사 도구를 사용하였다. 연구 결과, 통제 집단과 달리 실험 집단은 수업 전문성과 교수 효능감, 테크놀로지 통합 자아효능감이 유의하게 향상되었다. 사전 검사에서는 실험 집단과 통제 집단이 유의한 차이가 존재하지 않았지만, 사후 검사에서는 실험 집단이 통제 집단보다 수업 전문성이 유의하게 높았다. 이러한 결과를 통하여 프로그래밍을 활용한 TPACK 교육이 예비 교사의 수업 전문성 발달에 효과적인 것을 확인할 수 있었다.

본 연구에서는 박종원, 박종석, 이강길(2008)이 개발한 과학적 창의성 활동자료를 활용하여, 교사들이 직접 창의성 활동을 수행한 후에 지도 자료를 개발하는 워크숍 방식의 영재심화연수 프로그램을 개발하였다. 연수 결과, 교사들은 기존의 프로그램과 달리 다양한 프로그램과 지도전략을 배우고 실습할 수 있어, 영재지도를 위한 실질적인 목적을 연수를 통해 달성할 수 있었다고 응답하였다. 또한 프로그램들이 흥미롭고 난이도도 적절하여 앞으로의 영재교육에 적용할 계획이라고 응답하였다. 그리고 실제 연수활동을 관찰하여 교사들이 오랜 시간동안 집중적으로 활발하게 참여하였고, 과학개념의 올바른 이해에도 도움을 받았지만, 보다 더 창의적인 아이디어를 제안할 수 있도록 연습할 필요가 있음을 알 수 있었다. 마지막으로 교사들이 개발한 수업자료에서 잘한 부분과 부족한 부분을 찾을 수 있어, 이러한 부분이 앞으로의 연수 프로그램에 활용될 수 있을 것으로 기대되었다.

The purpose of this study is to develop and apply effective teaching strategies and program for the gifted-in-science. The teaching material for the gifted students was focussed on microscope. This study consists of three steps according to the enrichment triad model of Renzulli. Firstly, the gifted students investigate and express themselves for theological backgrounds, for examples, kinds, structure and use in various ways of microscope. It is to provide basic data for the effective ideas and interest which help students have the appropriate microscopic conceptions. In the second step, it contains understanding of a term and function of microscope, making of simple microscope, principle of a statue focusing and size estimation of an outline of subjects by scientific investigation activity. Lastly, it focussed on enlargement of post-learning through investigation of relationship with inter-science and experiments using microscope. Therefore, it was concluded that this study may help teachers reconsider scientific program development for the gifted or enriched students and to be successful in the teaching-learning processes.

The purpose of this research is to propose a program for teaching and learning effective problem-solving for gifted students based on abductive inference. The role of abductive inference is important for scientific discoveries and creative inferences in problem-solving processes. The characteristics of creativity and abductive inference were investigated, and the following were discussed: (a) a suggestion for a new program based on abductive inference for creative outcomes, this program largely consists of two phases: generative hypotheses and confirmative hypotheses, (b) a survey of the validity of a program. It is typical that hypotheses are confirmed in phases through experiments based on hypothetic deductive methodology. However, because generative hypotheses of this hypothetic deductive methodology are not manifest, we maintained that abductive inference strategies must be used in a Creative Teaching-learning Program for gifted science students.
