Objectives : The purpose of this study was to investigate the antioxidative effects of Ephedrae Herba extract. Methods : Total antioxidant status was examined by total antioxidant capacity(TAC), total antioxidant response(TAR) against potent free radical reactions, total phenolic content, DPPH radical scavenging activities, and the inhibitory effect of the extract on lipid peroxidation in rat liver mitochondria. Results : 1. TAC and TAR of Ephedrae Herba extract at the concentration of 5mg/ml were 3.76 and 1.65 mM Trolox equivalents , respectively. 2. Total phenolic content of Ephedrae Herba extract at the concenuation of 5mg/ml was 3.52 mM gallic acid equivalent. 3. Concentration of Ephedrae Herba extract at which DPPH radical scavenging activity was inhibited by 50% was 0.46mg/ml as compared to 100% by pyrogallol solution as a reference. 4. Ephedrae Herba extract at the concentration of 2mg/ml significantly decreased TBARS concentration by 97%, showing that Ephedrae Herba extract prevented lipid peroxidation at the low concentration. Conclusion : Thus antioxidant effects of Ephedrae Herba extract appear to be due to, at least in part, the prevention from free radicalsinduced oxidation, followed by inhibition of lipid peroxidation.

양성평등관점에 입각한 법사회화 이론의 비판적 검토

송성민 ( Seong Min Song ) 한국법교육학회 2011 법교육연구 Vol.6 No.1

The concept of legal socialization is that the process through which individuals acquire attitudes and beliefs about the law. At this point, These classic theories are admitted generally such as Cognitive Development(Piaget), Moral Development(Kohlberg), Legal Development(Tapp & Levine). In gender aspect, main ideas of these theories are masculine gender is prior to feminine gender in; learning legal knowledges, acquiring legal skills and attitudes etc. Legal developmental theory, however, has been pointed out the faults by some feminism critics such as Chodorow, Gilligan, Noddings. As applying these critics` view, this study was going to clarify the defects of legal socialization theories. the defects of the legal socialization theories can be conceptualized as followings. In gender equality perspective, Legal socialization theories have some limitations; of backgrounds, of applicable coverages, of conceptualizing ``citizenship``, of conceptualizing ``public sphere``, of consistent judgement. It is anticipated that legal socialization theories will be reinforced up and adequate more, thereby being made up the defects the above.

플립러닝(Flipped Learning)은 대안이 될 수 있을까?

송성민(Song, Seong-min) 학습자중심교과교육학회 2019 학습자중심교과교육연구 Vol.19 No.6

플립러닝은 일방적 지식 전달에 치중하는 전통적 수업 방식을 개선하기 위한 노력에서 등장한 새로운 수업 패러다임이다. 플립러닝이 학교 현장에서 널리 활용되고 이에 대한 연구도 왕성하게 수행되고 있으나, 이를 과신하거나 남용하는 문제 또한 커지고 있다. 이러한 문제의식에서 본 연구는 플립러닝의 본질관에 입각하여 일부 연구 경향을 비판적으로 분석해 보았다. 본 연구에서는 플립러닝의 본질을 크게 전환(flipped), 상호작용(interaction), 교수학습 문화(the culture of teaching and learning)로 정리하였다. 이러한 본질관에 입각하여 일부 연구를 분석한 결과, 패러 다임으로서 플립러닝의 취지를 제대로 구현하지 못하거나 엄밀하지 못한 연구 설계로 인해 플립러닝의 효과를 과장하고 효과의 기제를 명확히 설명하지 못하는 문제가 있음을 확인하였다. 그럼에도 불구하고 플립러닝의 본질적 의미와 미시적 변화에 주목하는 연구들도 존재함을 알 수 있었다. 이상의 연구 결과를 통해 플립러닝이 진정한 교수학습의 대안으로 자리매김할 수 있는 방향성이 무엇인지 제안하였다. Critics say that traditional teaching methods focus on only one-sided transfer of knowledge. Flipped learning has emerged in order to overcome this problem. Flipped learning is widely used on schools today. There are also many research on the effects of flipped learning, teaching strategy of flip-learning, etc. However, as flipped learning becomes more popular, misunderstanding are also increasing. In this case, flipped learning can not be used properly. Therefore, in this study, we looked at what the essence of flipped learning is, and then critically examined the research trends on flipped learning and the classroom cases. This study summarized the essence of flip learning as “flipped”, “interaction”, and “the culture of teaching and learning.” In other words, if flipped learning can not change the role, awareness, and climate of teachers and students as a whole, it comes to the conclusion that it is not proper flipped learning. I have criticized some research and teaching cases of flipped learning as follows : First, the effects of flipped learning might be exaggerated due to the inadequate research design. Second, some studies do not properly reflect the essence of flipped learning asa paradigm. Therefore, flipped learning should be considered as an real alternative model of teaching and learning.

사회과 통합형 평가문항의 유형 및 특성 분석 : 대학수학능력시험 및 국가수준 학업성취도평가 문항을 중심으로

송성민(Song, Seong-min),김재근(Kim, Jaegeun),배화순(Bae, Hwasoon) 학습자중심교과교육학회 2020 학습자중심교과교육연구 Vol.20 No.9

본 연구는 사회과에서 활용 가능한 통합형 평가 문항을 발굴하고 이를 몇 가지 유형으로 범주화한 후 그 특성을 도출하는 데 목적을 두고 있다. 이를 위하여 대학수학능력시험과 국가수준 학업성취도평가에 나타난 통합형 문항을 대상으로 자료 분류 및 분석을 수행하였다. 먼저 사회과 통합형 문항의 유형을 구분하기 위하여 발문-자료-답지의 3단 구성에 착안하여, 자료통합형, 답지통합형, 자료답지통합형, 통합소재형의 4가지 유형을 제안하였다. 다음으로 각 유형별 통합형 문항에 대한 깊이 있는 이해와 정성적 특성 도출을 위해 대학수학능력시험 및 국가수준 학업성취도평가 문항에서 유형별 대표문항을 선정하였고, 이를 분석하여 각 유형별 세부적인 특성을 제시하였다. 한편 통합의 유형에 따른 통계적 특성을 도출하기 위하여 유형별 통합 정도, 유형별 난이도의 관계에 대하여 교차분석을 수행하였고 각 유형별 특성에는 대부분 통계적으로 유의미한 차이가 있음을 확인할 수 있었다. This study analyzed the types and features of integrated social studies questions focusing on the College Scholastic Ability Test(CSAT) and National Assessment of Educational Achievement(NAEA). According to the analysis results, types of integrative social studies assessment items can be categorized into the followings: material integrative item, option integrative item, material-option integrative item, and integrative topic item. Representative items from each types were extracted from CSAT and NAEA to be analyzed for clearer understanding of their specific features. Furthermore, intensity of integration and difficulty of each types of items were also analyzed. The option-integrative item was weak in its intensity of integration, and exhibited relatively balanced difficulty. The material-option integrative item was stronger than option integrative item in its intensity of integration, and exhibited high or medium difficulty. Material integrative item exhibited little extremeness both in its intensity of integration and difficulty. Integrative topic item was strongest in an intensity of integration, and relatively lower level of difficulty.

사회과 선택교육과정 통합의 전략 연구 -법과 정치에서, 법과 정치로-

송성민 ( Seong Min Song ) 한국법교육학회 2010 법교육연구 Vol.5 No.1

본 연구는 2009 개정 사회과 선택과목 교육과정의 한 교과인 `법과 정치` 과목에 대한 교육과정을 통합의 측면에서 분석한 것이다. 분석의 준거를 설정하고, 문제점을 도출해내기 위한 기준으로서 통합교육과정이 갖는 의의와 필요성, 그리고 실제 통합의 유형과 방법에 대해서 살펴보았다. 특히 통합의 유형 가운데 학문적 형태의 측면에서는 다학문적, 간학문적, 초학문적 통합의 방식이 존재하고 있음을 알 수 있었으며, 향후 분석 결과 현행 `법과 정치` 과목은 다학문적인 통합 방식에 가깝다는 사실을 확인하였다. 이를 기준으로 `법과 정치` 교육과정이 가질 수 있는 문제점을 추출해 본 결과는 다음과 같다. 우선 기존 학문의 체계를 유지한 채, 법학과 정치학과 같은 모학문으로부터 개념을 그대로 끌어오고 있어, 학습자의 부담이 경감되지 않고, 교과서 집필과 현장 수업에서 어려움을 유발시킬 수 있다. 또한 실생활의 복잡 다양한 문제를 해결해나갈 수 있는 능력을 배양하고자 하는 목적을 달성하기 어려우며, 사회적 갈등과 이에 대한 해소 그리고 갈등해결의 제도화에 이르는 일련의 과정을 분절적으로 접하게 되어, 동태적 측면의 교육과정을 간과하게 된다. 따라서 이와 같은 문제점을 극복하기 위해 법학과 정치학 간의 간학문적인 통합을 이끌어 내야하며, 그 구체적인 내용 구성의 전략으로 핵심 주제와 이슈, 문제 등을 중심으로 유연한 내용 추출이 필요함을 제안하고 있다. This study is an analysis of curriculum related to `Law and Politics` -one of 2009 new social studies elective curriculum courses- which was analyzed in the aspect of integration. I set a standard of analysis, studied the meaning and necessity that integrated curriculum has as a standard to figure out the problem, types and ways of real integration. Especially in the sight of academic form among the types of integration, I found that there exist a way of multi-disciplinary, inter-disciplinary, trans-disciplinary integration. Also I confirmed that `Law and Politics` is close to the way of multi-disciplinary integration by the result of further analysis. With this standard, I found problems that `Law and Politics` curriculum can have. And the result is follows: First of all, it used a concept just same as the one from original studies such as law and politics, maintaining a system of its original discipline, so because of that learners still have big pressure and it can cause trouble in textbook writing and field teaching practice. Also it is hard to accomplish the purpose which is to cultivate the skills of solving complex problems, overlook an experimental curriculum by facing a series of courses which from social conflict and its resolution to institutionalization of conflict resolution. Therefore, to overcome these problems, we should draw inter-disciplinary integration between law and politics, and for specific contents construction strategy, I also suggest that we need to extract contents flexibly focusing key topics, issues, and problems.

대안적 법교육 패러다임의 제안 -형성적 법교육의 의의와 효과-

송성민 ( Seong Min Song ) 한국법교육학회 2014 법교육연구 Vol.9 No.1

우리나라의 법교육은 지난 반세기 동안 비약적인 발전을 거듭하여 시민교육으로서의 정체성을 확립해 왔지만, 여전히 일정한 한계를 가지고 있다. 본 연구는 이를 법교육 패러다임의 변천 과정으로 분석하여, 현재 법교육 패러다임이 시민교육적 정체성을 획득하였지만 여전히 수용적인 성격에 머무르는 한계가 있음을 지적하고 있다. 이를 극복하기 위해서는 자율적이고 능동적인 시민 자질과 소양을 길러줄 수 있는 ‘형성적 법교육’이 시행되어야 하는데, 이는 ‘민주적 법치사회의 구성과 유지에 필수적인 자율적이고 능동적인 법의식을 갖춘시민을 양성하기 위하여, 보편적 정의와 윤리 기준을 바탕으로 규범이나 법적 가치 등을 학습자 스스로 형성해 보는 경험을 강조하는 법교육 패러다임’을 말한다. 이러한 형성적 법교육은 목표, 내용, 방법의 측면에서 의의를 가지며, 법의식 개선에도 긍정적인 효과가 있음. 이 경험 연구를 통해 확인되었다. 따라서 자율적이고 능동적인 시민들로 구성된 바람직한 법치사회의 구현을 위하여 앞으로는 보다 적극적이고 자유로운 형태의 형성적 법교육이 강조되어야 할 것이다. Law-related education of Korea was launched in 1947, LRE has kept its line in the social studies education and has shown rapid growth in the 1990s. In the 1990s, academic discussion regarding the identity of LRE was vitalized, accelerating the academic development concerning the objective, contents and methods of LRE. In the early 2000s, with the establishment of the 7th Curriculum, ‘Law and Society’ achieved its independence in the highschool curriculum. But according to the researches such as ‘Investigation on the Legal Consciousness’, we still can find some problems in the legal consciousness of Korean citizens. That is, the overall legal consciousness of Korean citizens does not reach the desirable level of autonomy and independence. Based on this discussion, this research tried to explore the ideals of LRE which can foster the autonomous and independent civic virtues and qualities, and examined the educational effectiveness of such an alternative LRE paradigm. First, to analyze the meanings and limits of current LRE’s objectives, contents and methods, this research has paid attention to the changes in the LRE paradigm. The analysis results show that the LRE paradigm has shifted from the education of legal studies to citizenship education. But the actual LRE is not achieving its own emphasis on the learner’s autonomous class participation. In this context, this research has defined the current LRE paradigm as remaining in the nature of ‘acceptive’. And the targeted LRE, which can cultivate the autonomy and independence, overcoming the aforementioned limits, should be a ‘formative’ one. Formative LRE emphasizes the active participation of learners which is essential to be a desirable democratic citizen. This paradigm also emphasizes the contents that can cultivate the way of thinking of natural law. This formative LRE has the following 3 meanings in the aspects of objectives, contents, and methods. Based on this theoretical examination, to empirically analyze the effectiveness of formative LRE, an expected effects are extracted from a review of the literature. This research has concretized it to the 5 dependent variables of legal development level, legal intimacy, legal trust, legal efficacy, and intent to use law. The statistical analysis results are as follows. To verify the 1st question, paired t-test on the pre-test and post-test scores of treatment group was conducted. The analysis result indicates that the scores of all the dependent variables of legal development level, legal intimacy, legal trust, legal efficacy, intent to use law have increased. These statistics show that the formative LRE is effective in improving the legal attitudes. To verify the 2nd question, t-test on the post-test scores of the treatment group and control group has been conducted. There was also a considerable difference in the scores for legal intimacy, and legal efficacy variables. From these results, formative LRE is demonstrated to be more effective than acceptive LRE in cognitive and affective development. Based on these research results, an alternative LRE paradigm of formative LRE, can have both theoretical meaning and practical effective in overcoming the limitations of the current LRE paradigm. Consequently, a more autonomous and liberal form of LRE is required in order to realize the law-governed society of autonomous and active citizens.

사회과 교육과정 연구의 동향 분석

송성민 ( Seong Min Song ) 한국사회과교육학회 2013 시민교육연구 Vol.45 No.2

This article is aimed at exploratory analysis of trends of social studies curriculum researches and it also aims to draw implication about future direction of curriculum research from the analysis. The criteria of analysis include research topic, research method, research area and year of research publication. And based on this, frequency and cross-tab analysis is conducted. First, The results of domestic research trends are as follows: There are features accounted for the curriculum and textbook analysis being a large proportion of research topic, the quantitative research being a large proportion of research method and the research about entire area being a large proportion of research area. In addition to this, the number of social studies curriculum researches increases sharply since 2000. Also, this study found that in the area of curriculum transition and development, qualitative research is employed to a considerable at significant-level. Also, literature and theoretical research is significant in terms of curriculum research area. Lastly, quantitative research is significant in terms of curriculum and textbook analysis. The fact that qualitative research is prevalent in the early 2000`s and quantitative research is prevalent since the late 2000`s is a noteworthy feature. Next, the results of international comparative analysis are as follows: Compared to the foreign research, domestic research has a striking convergence to research topic and method aspects. Furthermore, we have found that our domestic research have a distinguishing research tendency: first, the field of individual subject curriculum is actively discussed and studied, second the number of study about curriculum field soars since 2000`s. We need to develop.
