When participating in problem-based learning (PBL), it is important for medical students to generate claims and provide justifications for their claims in small group discussions. This study aimed to investigate the effect of argumentation instruction on medical student learning experiences with PBL. A total of one hundred first-year preclinical students from Inje University College of Medicine, who had attended argumentation instruction, participated in this study. All of the participants completed a 5-point Likert scale questionnaire regarding their learning experiences with PBL, before and after the argumentation instruction. The questionnaire comprised 22 items with eight subcategories: argumentation activity, reflection, integration of basic and clinical science, identification of lack of knowledge, logical thinking, self-directed study, communication, and attitude toward discussion. The collected data were analyzed through a paired-sample t-test. The results of this study found that the argumentation instruction promoted the preclinical students' experiences with argumentation activities, reflection, an integration of basic and clinical science, the identification of their lack of knowledge, logical thinking, and self-directed study, and it increased positive attitudes toward group discussion. The findings suggest argumentation instruction can enhance medical student group discussions and help students achieve the objectives of PBL, including acquisition of basic and clinical science knowledge and development of clinical reasoning and self-directed learning abilities, which can highlight the meaningful learning experiences students have with PBL.

본 연구에서는 인터넷 메신저를 활용한 수업에서 이루어지는 과학 영재 학생들의 논변활동과 대화의 유형을 분류하여 수업 주제와 형태에 따라 나타나는 차이점을 분석하였다. 수업은 서울대학교 영재센터 학생 가운데 선발된 5명의 남학생을 대상으로 하였으며, 인터넷 메신저 프로그램을 활용하여 진행되었다. 학생들의 논변활동은 Toulmin의 논쟁 틀에 바탕을 두어 분석되었으며, 논변활동 요소의 흐름에 따라 논변활동을 유형화하였다. 연구 결과 학생들의 수업 참여의 기회가 높은 수업에서 상대적으로 높은 수준의 논변활동이 나타났으며, 전체 수업에 걸쳐 4가지의 논변활동 유형이 나타났다. 이러한 결과는 학생들의 논변 능력 향상과 교수자-학습자간의 상호작용 촉진을 위한 수업 모형의 개발과 적절한 주제 선정이 필요함을 시사한다.

본 연구에서는 논증 구조 교육을 실시한 후 학생의 과학 글쓰기에서 나타나는 논증 구조 변화와 과학 개념 및 지식이 어떻게 달라지는지 알아보고자 하였다. 이를 위해 수도권에 위치한 고등학교 2학년 자연계열여학생 중 7명을 선정하여 한 달 동안 총 40시간에 걸쳐 논증 구조 교육을 실시하였다. 논증교육을 실시하기 전과 후 설명, 실험-상세묘사, 논증 등 각각의 과학 장르에 대해 학생들의 글쓰기에 어떠한 변화가 있는지를 분석하였다. 그 결과 세 가지 장르 모두에서 유의미한 변화를 발견 할 수 있었다. 설명과 실험-상세 묘사 장르에서는 논증 요소들이 더 다양하고 풍부해질 뿐만 아니라, 과학 개념 및 지식이 더 구체적이고 세부적으로 변하였다. 논쟁 장르에서도 글의 구조가 단순 논증 구조에서 벗어나 근거를 여러 가지 다양한 방법으로 제시하게 되는 다중 논증 구조나 종속 논증 구조의 형태로 바뀌었으며, 논증 요소들의 종류와 수도 많아짐을 확인할 수 있었다. 이는 학생들이 논증 구조를 세우는 과정을 통해 과학 개념들에 대한 이해를 확고히 하게 됨을 의미하며, 체계적인 논증 구조 교육의 필요성을 시사한다.

The purpose of this study is to examine the efffcts of science instruction using argumentation, with Tolumin's structure of argument, on students' learning motivation and scientific attitude. In the instruction, well-structured problems selected to be argument, in which interactions among students are stressed. The subjects were classified into two groups: One group is composed of sixty-seven students (experimental group) who were participated in solving processes of the scientific argument tasks, and the other is composed of sixty-nine students (comparative group) who were participated in the traditional teaching method. The results of this study implied that experimental group has a positive effect on students' learning motivation and scientific attitude.

The purpose of this study was to investigate the effect of scientific argumentation on argument tasks with incorrect alternative ideas in elementary science classes. The subjects were 41 fourth graders of 2 classes in an elementary school. In the experimental group, argument tasks with pictures including incorrect alternative ideas were suggested in order to facilitate argumentation. Students were asked to perform argumentation with the component of claim, evidence, and reasoning. In the control group, textbook-based traditional instruction was used. The results showed that scientific argumentation activities on argument tasks with incorrect alternative ideas had positive effects on students' science achievement and science-related affective domains. The analyses of students' argumentation revealed that argument tasks with incorrect alternative ideas could facilitate students' participation and exposure of their preconceptions. It also led students to find and connect evidence to support their claims. In some cases, students had difficulty in making appropriate argumentation because of unclear experimental data and/or invalid reasoning. Educational implications were discussed.

본 연구에서는 중학교 과학에서 논의를 강조한 탐구적 과학 글쓰기(SWH) 교수-학습 전략에 따른 수업 프로그램을 개발하고 실시하여 이 프로그램이 학생들의 인지수준 발달, 과학개념 이해, 논의 및 글쓰기의 향상에 미치는 영향을 알아보고자 하였다. 이를 위해 남녀공학 중학교 2학년 학생 132명을 선정하여 실험집단과 비교집단으로 임으로 배정하였다. 실험집단에는 SWH 수업전략을, 비교집단에는 교사중심의 전통적인 수업을 적용하였다. 그 결과 이 연구에서 개발한 수업 전략이 학생들의 인지수준 발달, 과학개념 개념이해와 논의, 글쓰기에 효과적인 것으로 나타났으나 논의과정 요소 중보장, 보강, 한정, 반증, 메타인지에는 유의미한 효과가 없는 것으로 나타났다. 이는 논의를 강조한 탐구적 과학 글쓰기(SWH)가 실험집단의 과학개념 이해와 과학적 글쓰기 능력의 향상에 효과적이었음을 나타내며 단방향적인 글쓰기뿐만 아니라 전체적인 논의과정 능력의 질적 향상을 위한 수업전략의 개발이 요구됨을 시사한다.

Current interest in mathematics learning that focuses on understanding, mathematical reasoning and meaning making underscores the need to develop ways of analyzing classrooms that foster these types of learning. In this paper, the author show that the constructs of social and socio-mathematical norms, which grew out of taking a symbolic interactionist perspective, and Toulmins scheme for argumentation, as elaborated for mathematics education by Krummheuer [The ethnology of argumentation. In: The emergence of mathematical meaning: Interaction in classroom cultures (1995, pp. 229-269). Hillsdale, NJ: Erlbaum], provide us with means to analyze aspects of explanation, justification and argumentation in mathematics classrooms, including means through which they can be fostered. Examples from a variety of classrooms are used to clarify how these notions can inform instruction at all levels, from the elementary grades through university-level mathematics.

The purpose of this study is to examine the effects of science writing heuristic(SWH) instruction based on Tolumin's structure of argument, on students' science process skills and scientific attitude. In the instruction, unstructured problems were selected with issues to be argued, in which interactions among students are stressed. This research involved 58 students of 5th grade at an elementary school, and divided them into an experimental group with 29 and a control group with 29. The former was treated with instruction using argumentation as SWH, while the latter with conventional ways of instruction. Science process skills and scientific attitude were compared between the two groups and within each of the groups. The results implied that science instruction using science writing heuristic is effective in improving learning science process skills and scientific attitude.
