In this study, it is assumed that understanding the nature of science (NOS) would enhance students' performance of scientific inquiry in more authentic ways. The ultimate goal of this study is to suggest new models for developing scientific inquiry activities through understanding the NOS by linking the NOS with scientific inquiry. First, the various definitions and statements of the NOS are summarized, then the features of the developmental nature of scientific knowledge and the nature of scientific thinking based on the philosophy of science are reviewed, and finally a synthetic list of the elements of the NOS is proposed, consisting of three categories: the nature of scientific knowledge, the nature of scientific inquiry, and the nature of scientific thinking. This suggested synthetic list of the NOS is used to suggest a model of scientific inquiry through the understanding of the NOS. This list was designed to provide basic standards regarding the NOS as well as practical guidance for designing activities to improve students' understanding of the NOS.

This article arose from the previous studies, which suggested a synthetic list for the nature of science (NOS), discussed the relationship between the NOS and scientific inquiry and the development of the NOS in the context of scientific inquiry. In this article, for teaching scientific inquiry through the NOS, I proposed three teaching models - reflection, interaction, and the direct model -. Within these teaching models, understanding the NOS is viewed as a prerequisite condition for the improved performance of scientific inquiry. In the reflection model, the NOS is embedded and reflected in scientific inquiry without explicit introduction or direct explanation of the NOS. In the interaction model, concrete interaction between scientific inquiry and the NOS is encouraged during the process of scientific inquiry. In the direct model, subsequent to directly comprehending the NOS at the first stage of activity, students conduct scientific inquiry based on their understanding of the NOS. The intention of this present article is to facilitate the use of these models to develop teaching materials for more authentic scientific inquiry.

Even though the importance of the nature of science (NOS) and scientific inquiry in science learning have been emphasized by many science educators and science curriculums, the link between the NOS and scientific inquiry has not been discussed sufficiently. In this article, I discussed that various aspects of NOS are already embedded in defining and characterizing the authentic scientific inquiry and that we need to have special concern about how the NOS should be treated and interpreted when introducing it into scientific inquiry. And I summarized two approaches to teach the NOS and scientific inquiry; teaching the NOS through scientific inquiry and teaching scientific inquiry through the NOS. Finally, some next studies based on this article are introduced.

An alternative vision for science inquiry that appears to be important and challenging is model-based inquiry in which students generate, evaluate and revise their explanatory model. Pre-service teachers should be given opportunities to develop and use their mechanistic explanatory models in order to participate in the practice of science and to have a sound understanding of science. With this view, this study described a case of pre-service elementary teachers' scientific modeling in magnetism. The aims of this study were to explore difficulties preservice elementary teachers encountered while they engaged in a model-based inquiry, and to examine how their understandings of the nature of scientific models changed after the model-based inquiry. The data analysis revealed that the pre-service teachers had difficulties in drawing and writing their own thinking because they had little experience of expressing their own science ideas. When asked to predict what would happen, they could not understand what it meant to make a prediction "based on their model". They did not know how to use or consider their model in making a prediction. At the end of the model-based inquiry they reached a final consensus of a best model. However, they were very anxious about whether the model was the "correct" answer. With respect to the nature of scientific models, almost all of the pre-service teachers initially viewed models only as a communication tool among scientists or students and teachers to help understand others' ideas. After the model-based inquiry, however, many of them understood that they could create, test, and revise their "own" models "by themselves". They also realized the key aspects of scientific models that a model can be changed as evidence is accumulated and a model is a knowledge production tool as well as a communication tool. The results indicated that pre-service elementary teachers' understandings of the nature of scientific models and their previous school science experiences could affect their performance on a model-based inquiry, and their experience of scientific modeling could help them enhance their understandings of the nature of scientific models.

이 연구에서는 과학 탐구의 본성에 대한 명시적-반성적 탐구 학습 프로그램을 개발하고 적용하여 그 효과를 과학 탐구의 본성을 직접 가르치지 않은 암시적 탐구 수업과 비교하였다. 또한, 개발된 프로그램 및 암시적 탐구 수업에 대한 학생들의 인식을 비교하였다. 중학교 2학년 학생들을 두 집단에 배치하였다. 처치 집단에서는 과학 탐구의 본성에 대한 명시적-반성적 탐구 학습 프로그램을 실시하였고, 통제 집단에서는 과학 탐구의 본성과 관련된 내용을 제외하고 처치 집단과 동일한 탐구 활동을 사용한 수업을 실시하였다. 연구 결과, 처치 집단의 수업이 학생들의 과학 탐구에 대한 인식론적 견해를 향상시키는데 효과적이었다. 그러나 두 집단의 과학 성취도와 과학 수업에 대한 즐거움에는 통계적으로 유의미한 차이가 없었다. 처치 집단의 학생들은 과학 탐구의 본성에 대한 소집단 토론 활동을 수업의 장점으로 생각하였으며, 소집단 토론 활동이나 과학 탐구의 본성에 대한 이해, 자신의 생각을 글로 쓰고 발표하는 활동 등을 어려움으로 인식하는 것으로 나타났다. 이에 대한 교육학적 함의를 논의하였다.

In response to epoch-making development in science and technology, the innovative curricular materials have been begun to develop since the late 1950s and early 1960s. However, the new inquiry-centered materials have failed to be successfully used in teaching/learning practices of science. Among the various reasons for the failure, the very nature of the inquiry approach has been identified as the most critical problem. Nevertheless, fostering inquiry faculties on the part of the students has been emphasized as one of the most important objectives of science instruction. Therefore this study was conducted for the purpose of developing a practical inquiry-oriented instructional method. In order to obtain this goal the nature of scientific inquiry was analyzed and the status quo of science education in which inquiry-oriented instructional strategies were applied was examined. The results of the study are described in this paper.

본 연구에서는 2015 개정 교육과정 고등학교 통합과학 교과서에 나타난 과학의 본성(NOS) 분포를 분석하였다. 분석 대상은 2015 개정 교육과정으로 출판된 통합과학 교과서 5종 모두를 분석하였으며, 분석의 개념적 틀로는 과학적 소양 기반 4가지 영역의 과학의 본성(NOS)(Lee, 2013)을 활용하였다. 4가지 영역의 과학의 본성(NOS)은 1. 과학지식의 본성(nature of scientific knowledge), 2. 과학적 탐구의 본성(nature of scientific inquiry), 3. 과학적 사고의 본성(nature of scientific thinking), 그리고 4. 과학과 기술 및 사회의 상호작용의 본성(nature of interactions among science, technology, and society)이다. 분석은 2명의 분석자가 수행하였으며, 두 분석자간의 신뢰도는 Cohen's kappa 계수 0.83 ~ 0.96으로 비교적 높은 신뢰도 값을 나타냈다. 분석 결과는 다음과 같다. 첫째, 2015 개정 교육과정 통합과학 교과서에서는 과학의 본성(NOS) 4가지 측면 중에서 '과학탐구의 본성(nature of scientific inquiry)' 영역을 전반적으로 가장 강조하고 있었다. 이것은 통합과학 교과서 5개 출판사 전체 영역에서 '과학 탐구의 본성(범주 II)'의 분포가 평균 약 44 %로 나타나는 것에서 확인할 수 있었다. 둘째, 2015 개정 교육과정 통합과학 교과서는 출판사에 상관없이 '과학탐구의 본성(범주 II)'을 가장 강조하고 있었지만, 그외 다른 측면의 과학의 본성(NOS) 부분은 출판사별로 다소 차이가 나타나고 있었다. 따라서 통합과학 교과서들은 과학적 내용과 활동을 탐구하는 방법으로서 주로 제시하면서 출판사별로 다소 다르게 과학의 본성(NOS) 특징을 강조하고 있다고 말할 수 있다. 셋째, 2015 개정 교육과정 통합과학 교과서에서 강조하는 과학의 본성(NOS) 측면은 4. 환경과 에너지 단원을 제외하고 모든 단원에서 유사하게 나타났다. 이것은 과학의 본성(NOS) 단원별 분석 결과가 대부분의 단원에서 전체 교과서 분석 결과와 유사한 양상이었으며, 4. 환경과 에너지 단원에서만 범주 II의 '과학 탐구의 본성' 영역 다음으로 '과학-기술-사회와 상호작용하는 과학의 본성(STS)(범주 IV)'이 강조되고 있는 것에서 확인할 수 있다. 이와 같은 결과는 2015 개정 교육과정 통합 과학 교과서가 지난 교육과정에 비하여 비교적 다양하고 균형 있는 과학의 본성(NOS) 측면을 제시하고 있으며, 2015 개정 교육과정의 목표인 과학적 문제해결력과 창의력 증진을 위하여 과학적 탐구를 강조를 하고 있다는 것을 알 수 있었다.

This study examined the knowledge and practices of scientific inquiry displayed by three student teachers and two beginning teachers at secondary levels. Observations using the instrument of OTOP designed by the research team of OCEPT (Oregon Collaborative for Excellent in the Preparation of Teachers) generalized similar teaching strategies of scientific inquiry between student and beginning teachers, such as using group work for students' first hand experience, using concrete materials for experimentation or visual tools for demonstration, using questions for factual knowledge mainly without opportunities to understand how scientific knowledge is constructed. Those scientific inquiry activities were very confirmative ones to follow the steps without opportunities of understanding nature of science or nature of scientific inquiry. However, all participants in this study hold knowledge of scientific inquiry envisioned by the National Science Education Standards [NSES] (NRC, 1996), where students identify their hypothesis, use critical and logical thinking, and consider alternative explanations through argumentation as well as experimentation. An inconsistent relationship between participating teachers knowledge and practices about scientific inquiry resulted from their lack of pedagogy skills of implementing it in the classroom. Providing opportunities for these teachers to reflect on their beliefs and practices about scientific inquiry was recommended for the future study. Furthermore, increasing college faculty interest in new teaching approaches for upgrading the content knowledge of student teachers and beginning teachers was recommended as a solution, since those teachers showed evidence of influence by college faculties at universities in their pedagogy skills.
