동화해석의 다양성에 관한 연구: 신데렐라를 중심으로

정은실 대한문학치료학회 2015 대한문학치료연구 Vol.5 No.1

본 연구에서는 동화해석의 다양성을 연구하기 위해 그림형제 동화 신데렐라를 사회심리학적, 정신분석학적, 분석심리학적으로 분석한 것을 고찰해 보았다. 이를 통해 동화 해석학자들이 찾아낸 삶의 지혜를 탐색해 보았다. 신데렐라를 사회심리학적으로 해석한 다울링은 여성 억압적인 사회문화에 길들어져 홀로 서려는 의욕을 잃고 남편에게 의지하려는 여성들의 의존적 성향을 떨쳐버리고, 더 이상 사회의 억압에 구속되지 말고 자신의 본질을 찾아서 자율적인 인간이 될 것을 촉구하고 있다. 정신분석학적으로 해석한 베텔하임은 무의식속에 깊이 억압된 외디푸적 욕망을 의식화하여 아동이 가질 수 있는 외디푸스적인 환멸, 거세불안, 자기비하 등에서 벗어나 자율성과 근면성 그리고 긍정적인 자기 정체성을 획득할 것을 요구한다. 분석심리학적으로 분석한 율라노프는 신데렐라의 선함과 계모와 의붓 언니들의 악함을 뚜렷이 대비시키면서 자매간 경쟁과 시기심을 이길 수 있는 선함의 길을 제시한다. 분석심리학적으로 분석한 드레버만은 아니마와 아니무스의 만남을 통해 분열된 다양한 내적 성격요인들이 통합되어 전체성을 이룰 때 주인공은 개성화와 자기실현을 이룰 수 있음을 드러내고 있다.

초등학교 수학과 문제해결 교육 재고

정은실 한국초등수학교육학회 2015 한국초등수학교육학회지 Vol.19 No.2

이 연구의 목적은 우리나라의 초등학교 수학과 문제해결 교육은 어떠했는지를 반추해보기 위해 그동안 우리나라 초등학교 문제해결 지도의 역사를 되돌아보고, 초등학교 수학과 교육과정과 교과서 분석을 통해 문제해결이 어떻게 다루어졌는지를 알아보기 위한 것이다. 그 결과 제4차 교육과정부터 2009개정 교육과정 현재까지 문제해결이 계속 강조되어 왔으나, 그에 따른 교과서에서는 교육과정을 제대로 반영하지 못한 경우가 많음을 알 수 있었다. 또한 제6차 교육과정에서 문제해결에 대한 교육이 양적으로 가장 많은 부분을 차지하다가 그 이후 조금씩 약화되고 있으며, 2007, 2009 개정 교육과정에서는 문제해결을 위한 교육으로 전환하려는 움직임이 있음을 알 수 있었다. 문제해결을 통한 지도는 제대로 이뤄지지 못하고 있다. The purpose of this study is to reconsider of teaching mathematics problem solving in Korea's elementary school through an analysis of mathematics curricula and mathematics textbooks of the elementary school. As a result, it is found that the problem solving had been emphasized continually from the 4th curriculum to the 2009 revised curriculum. However, contents in their textbooks did not reflect the intent of the mathematics curricula properly. And amount of contents related to teaching about problem solving in the textbooks reached the peak in the 6th mathematics curriculum. Then teaching about problem solving had been weakened gradually. And it is also revealed that there had been a movement to change to teaching for problem solving in the textbooks of the 2007 and 2009 revised curricula. Teaching via problem solving had not been carried out appropriately so far.

언어로서의 수학에 대한 연구

정은실 晋州敎育大學校 科學敎育硏究所 1997 科學敎育硏究 Vol.23 No.-

The purpose of this article is to take the claim that 'mathematics is a language', and to explore what some of the consequences of so doing are. Like all language, mathematics has its unique characteristics. Mathematics is both oral and written. Like all language, mathemaics is an important means of communication. People communicate through language, both spoken and written, through graphic and through their actions. Each mode has receptive and expressive language. Mathematics classrooms need to encourage expressive language and the whole range of communication modes-oral, written, graphic and active-should be used, in order to broaden and deepen students' understanding of mathematics. Until recently, foreign language teaching tended to be a formal affair, which was largely rule-based. However there has been a rapid upsurge in interest in the notion of communicative language teaching, that is to say, attempting to teach communicative comptence in a language. Mathematics teaching still suffers from the same difficulties as the former teaching strategy for foreign languages. One implication brought about by seeing mathematics teaching as language teaching could be a change in focus from the study of a rule-governed abstract system to one of the acquisition of communicative competence about certain objects, situations and phenomena.

정은실,박애선 한국상담심리학회 2005 한국심리학회지 상담 및 심리치료 Vol.17 No.4

The purpose of this study is to examine whether a group counseling program using Reality Therapy is an effective tool to develop youth leadership life skills. The participants were 29 high school students from the Kyong-Gi province, who were all in second grade. The students were divided into two groups: the experimental group with 14 students and the control group consisting of 15 students. The experimental group received the group counseling program using Reality Therapy twice a week for a total of 10 sessions that included an orientation session. Each session lasted two and half hours. The control group received no treatment. A Pretest-Posttest Control group design was used in this study. Leadership Life Skills was administered to the groups before and after the program to measure the effectiveness of the program. Results of this study support the hypothesis that the group counseling program using Reality Therapy has a positive influence on developing the leadership life skills for the youth. The leadership life skills significantly increased in experimental group as compared to control group. This is the first research to investigate the relationship between Reality Therapy and youth leadership. This study shows that a group counseling program using Reality Therapy could be an effective tool to develop youth leadership. This study introduces the integrated concept of leadership to counseling psychology; it provides us with an opportunity to understand and support the developmental tasks of youth from an angle of leadership. 본 연구의 목적은 현실요법 집단상담 프로그램이 청소년의 리더십 생활기술을 개발시킬 수 있는 효과적인 도구인가를 검증하는 것이다. 연구대상은 경기도에 위치한 K 고등학교 2학년 남여학생 29명이었으며, 실험집단에 14명, 통제집단에 15명을 배치하였다. 실험집단에는 오리엔테이션 회기를 포함하여 총10회기의 현실요법 집단상담 프로그램을 주2회, 각 회기별 2시간30분 동안 처치하였으며, 통제집단에는 아무런 처치도 하지 않았다. 사전-사후검사 설계를 하였고, 현실요법 집단상담 프로그램의 효과를 측정하기 위해 리더십 생활기술 척도를 사용하여 집단상담 프로그램 적용 전과 후에 실험집단 통제집단 두 집단에 검사를 실시하였다. 연구결과 현실요법 집단상담 프로그램이 청소년의 리더십생활기술의 개발에 긍정적인 영향을 미칠 것이라는 본 연구의 가설은 지지되었다. 실험집단은 통제집단에 비하여 리더십생활기술이 의미 있게 향상되었다. 이 연구는 현실요법과 청소년 리더십간의 관계를 다룬 최초의 연구로서, 현실요법 집단상담 프로그램이 청소년들의 리더십을 개발시킬 수 있는 효과적인 도구가 될 수 있음을 보여주었다. 본 연구의 의의는 리더십이라는 통합적인 개념을 상담심리학에 도입함으로써, 청소년기의 여러 발달과제들을 리더십 개발의 관점에서 보다 통합적으로 바라보고 지원할 수 있는 기회를 제공하였다는 것이다.

실천으로서의 수학에 대한 小考

A practice is classified into the practice as a content and the practice as a method. The former means that the practical nature of mathematical knowledge itself should be a content of mathematics and the latter means that one should teach the mathematical knowledge in such a way as the practical nature is not damaged. The practical nature of mathematics means mathematician's activity as it is actually done. Activities of the mathematician are not only discovering strict proofs or building axiomatic system but informal thinking activitiies such as generalization, analogy, abstrction, induction etc. In this study, it is found that the most instructive ones for the future users of mathematics are such practice as content. For the practice as a method, studets might learn, by becoming apprentice mathematicians, to do what master mathematicians do in their everyday practice. Classrooms are cultural milieux and microsoms of mathematical culture in which there are sets of beliefs and values that are perpetuated by the day-to-day practices and rituals of the cultures. Therefore, the students' sense of what mathematics is really about is shaped by the culture of school mathematics. In turn, the sense of what mathematics is really all about determines how the students use the mathemaics they have learned. In this sense, the practice on which classroom instruction might be modelled is that of mathematicians at work. To learn mathematics is to enter into an ongoing conversation conducted between practicioners who share common language. So students should experience mathematics in a way similiar to the way mathematicians live it. It inplies a view of mathematics classrooms as a places in which classroom activity is directed not simply toward the acquisition of the content of mathematics in the form of concepts and procedures but rather toward the individual and collaborative practice of mathematical thinking.

This paper aims to consider and the need of Vergnaud's conceptual field, and to review the conceptual multiplicative structures, in order draw the educational implications. The conceptual field of multiplicative structures is the set of situations the solutions of which involves a multiplication, a division, or a combination of such operations. This set is generated by three different subtypes : isomorphism of measures, product of measures, and multiple proportion that can be in a variety of ways. The conceptual field of multiplicative structures is also a set of interconnected concepts : measures, scalar ratio, quotient and product of dimensions, fraction, rate, rational number, vector space, linear and n-linear function, constant coefficient, linear combination and linear mapping, and of course multiplication and division. The educational implications are drawn from the emphasis of situations, the relation of intuitive knowledge and formal knowledge, the systematic work, both theoretical and empirical.

Research on Securing Water Resources through Cloud Seeding during Dry Season

정은실 한국수처리학회 2022 한국수처리학회지 Vol.30 No.6

Climate changes directly link to water shortages in many countries, and a cloud seeding experiment has been proposed as a way to alleviate water shortage and severe air pollution problems. In Korea, ground-based snow enhancement experiments have been conducted at the cloud physics observation site (CPOS) of the Daegwallyeong area in Gangwon province since 2006. In this study, we analyzed 102 seeding experiments conducted from 2006 to 2015 to find the optimal conditions for silver iodide (AgI) seeding to increase snow amount. The results showed that snow increased due to the AgI seeding if the surface temperature was lower than -4°C and the liquid water was sufficient in the clouds. Of the 102 snow enhancement experiments performed over the past 10 years, only 20 cases met one of these conditions. The optimal conditions found are expected to help secure water resources by increasing the success rate of future AgI cloud seeding experiments. During the experiments, 25 to 113 g of AgI was used in each experiment, indicating that the amount of AgI was sprayed into clouds and eventually fell to the ground as rain, further lakes, and groundwater contained AgI. Although there is controversy over the harmfulness of AgI used in cloud seeding experiments, AgI is known to have no harmful effects either experimentally or environmentally. The study further showed that the increase in snow depth decreased as the amount of AgI seeding material increased, just as precipitation decreased as atmospheric PM10 increased.
