The purpose of this study is to explore teachers' responsive moves that affect students' argumentation practices, and to propose responsive teaching strategies in argumentation-based science classroom. Two teachers, who have not implemented argumentation in their classes, and 57 students, participated in this study. We recorded and transcribed their classes and interviews for the analysis. According to grounded theory approach, we categorized the teachers' responsive moves as focused on either structural or dialogical aspects of argumentation, and qualitatively analyzed their responsive teaching practices in classes. We discovered that the teachers mostly responded to structural rather than dialogical aspects of argumentation, particularly during the students' small-group discussions. This was mainly due to their instructional goals, which focused on the structural aspect of argumentation, and the limited time available for supporting small-groups. Regarding the structural aspects, those responsive moves that explored the students' thinking or facilitated their reasoning helped them to share their thinking and justify their arguments further with recognition of learning goals in the argumentation activities. Regarding the dialogical aspects, which were seen mostly in whole-class discussions, the moves that underlined similarities and differences between arguments, facilitated the sharing of a small-group's arguments with the entire class, or asked a specific student to evaluate the arguments were notable. These moves supported clarification of various small-groups' arguments, which led to reconstruction of coherent argument through evaluation and rebuttal of these arguments, consequentially facilitating dialogical interactions. Based on these results, we proposed responsive teaching strategies in an argumentation-based science classroom.

Misconceptions are one of the most important and long-lasting studied themes on science education. It is because their nature is obstinate and settled as well as they corrupt students' understanding of science concepts. This study examines whether preservice elementary school teachers enrolled in biology teaching material research course changed positively on science teaching efficacy and correcting life science misconceptions when they used the handbook developed for this study. The handbook comprises 203 life science concepts surveyed among preservice teachers holding from advanced researches and arranged by 2007 Revised Science Curriculum. 107 preservice elementary school teachers participated in the study. Forty-six (46) of them were assigned to the experimental group and the other 61 to the control group. ANOVA was conducted for analyzing data. Science Teaching Efficacy Belief Instrument (STEBI) and the life science misconception test which was developed for this study, were administrated as assessing instruments for pretest and posttest. The experimental group, using the handbook, acquired higher scores in both tests on statistical significance level than the control group who were not using the handbook. The results indicate the handbook developed for correcting life science misconceptions for this study is effective in enhancing science teaching efficacy and correcting life science misconceptions.

2011년 동일본 대지진으로 발생된 지진해일로 인해 막대한 경제적 손실과 인명피해가 발생하였고, 2차적 사회적 피해가 지속되고 있다. 또한 국내에서도 최근 경주와 포항지역에서 지진이 발생하여 피해가 발생함에 따라 재난의 불확실성에 대한 대비의 중요성이 강조되고 있고, 과거 안전하다고 했던 재난에 대한 위험성에 대해 국민들의 관심이 증대되었다. 피해사례가 2차례 있는 지진해일의 경우도 동일본 대지진 이후로 전 세계적으로 해일에 대한 위험성이 재평가되고 있다. 지진해일은 해저에서 발생하는 지진에 의한 것으로 발생지점 및 강도 등을 예측하기가 쉽지 않으므로, 지진발생에 대한 가상 시나리오를 이용한 연구가 진행되고 있다. 가상 시나리오를 활용하여 현재까지 많은 침수예상도가 제작되었으나, 다양한 시나리오 대해서 검토되지 않았다. 따라서 본 연구에서는 과학적 보간법을 이용하여 수치모형을 수행하지 않고 기수행된 연구 DB를 활용하여 지진해일 피해를 예측하는 기술을 개발하였다. 연구 DB는 국립재난안전연구원에서 수행된 지진해일 자료를 활용하였고, 전국단위를 기반으로 지진규모 7.0~9.0 내에 지진해일을 유발하는 지진에 대해 지진해일의 피해를 예측할 수 있는 기술을 개발하였다. 기술을 검증하기 위해 5개의 진원지에 대하여 과거 발생 지진규모부터 극한의 지진규모를 가정한 수치모의 결과와 본 연구의 결과를 비교하였다. 본 연구는 격자 1km인 광역모형의 모의결과를 활용하였으므로 실제로 해안지역의 침수양상의 정확도가 높지 않지만 향후 고정밀 공간해상도에 대하여 모의를 수행한다면 지진해일로 발생하는 범람 및 침수를 보다 정밀하게 예측할 수 있을 것이라 기대된다.

In a sense that achievement emotion is directly associated with achievement activity of students and its result, drastic changes in educational environment such as expansion of e-learning due to COVID-19 may have a large impact on the achievement emotion of students inevitably. However, studies on the foregoing still remain insufficient, and development of a questionnaire capable of making a quantitative measurement on the achievement emotion of students under the environment of e-learning may become the basis of relevant studies, so this study developed the e-learning Achievement Emotions Questionnaire-Korean Middle school Science(e-AEQ-KMS) and verified its validity. e-AEQ-KMS in this study was developed based on the Achievement Emotions Questionnaire-Korean Middle school Science (AEQ-KMS) and by reflecting characteristics of e-learning science class. With 226 questions in total, the questionnaire is composed to measure 9 kinds of achievement emotion such as enjoyment, hope, pride, relief, anger, anxiety, hopelessness, shame, and boredom under 3 academic situations of class situation, learning situation and testing situation. The result of this study has a great significance in the way that it set out a framework for making a comparative analysis quantitatively on the achievement emotion of Korean middle school students in science for e-learning classes.

The purpose of this study is to explore the measurement of attitude towards science based on social constructivism and the application of this scale. The data were collected using questionnaires from 833 middle school students in the second grade. First, factor analysis were used to assess the construct validity of the scale of Reputation in Culture Border Crossings (R-CBC) developed by Krogh and Thomsen (2005). This finding indicated the construct validity of R-CBC scale based on social constructivism. Second, the correlation among two scales based on social constructivism and Test of Science-Related Attitudes (TOSRA) scale based on individual constructivism were investigated to examine the convergent validity and the discriminant validity. The R-CBC scale was correlated with Simpson-Troost Attitude Questionnaire (STAQ) scale but the R-CBC scale and TOSRA scale were not connected. Third, students' attitude toward science assessed by three forms of measurements were compared according to the choice of high school type. Students' attitude toward science measured by R-CBC scale and STAQ scale were different in three types of high school. This finding indicated that two scales based on social constructivism are useful measurements that can predict the choice of high school type.

The purpose of this study was to test effects of the Triple Abduction Model (TAM) for improving the skills of scientific hypothesis generation in science learning. Twenty-six students were selected for the TAM group and 27 others were selected for a traditional group from one high school. Researchers developed and administered 10 TAM and traditional-style activities. The degree of hypothesis explanation was evaluated during the experimental treatment. Each Subjects' ability in scientific hypothesis generation was assessed by the Science Knowledge Generation Test A and B. Test A was used as a protest and B for a posttest. The results of this study revealed that the degree of hypothesis explanation of TAM was significantly higher than the degree of the traditional group, and the mean of the TAM group was equal to the mean of traditional group on the pretest. Additionally, the mean of the TAM group was significantly higher than the mean of the control group on the posttest. Therefore, instruction with TAM was more effective than the instruction using traditionals method for increasing students' hypothesis generation skills.

6차 교육과정부터는 과학 교육에서 학생들의 학습 목표를 과학 개념에 대한 이해 뿐 아니라 탐구 사고력 및 기능 향상도 중요한 목표로서 취급하고 있다(교육부, 1992). 그런데 학생의 탐구 사고력을 향상시킬 수 있는 과학교육이 제대로 이루어지지 못하고 있는 것이 현재의 실정이다. Schwab(1961)가 탐구 학습의 단계를 분류하면서 지적한 바 있듯이 탐구는 주어진 과제를 해결하는 고정적 탐구보다는 스스로 과제를 설정하고 이를 해결하려 하는 유동적 탐구가 더 바람직한 방향이며, 이러한 유형의 탐구를 통하여 학생들은 창의성의 신장과 함께 과학적탐구가 이루어지는 과정을 더 올바르게 이해할 수 있을 것으로 생각된다. 따라서 탐구의 상황을 학교 실험실만이 아닌 좀 더 생활 주변의 여러 가지 경험과 관련된 쪽으로 안내하는 것도 필요하다. 최근 활발한 컴퓨터의 보급과 인터넷 환경의 확대로 인하여 학생들이 이러한 환경에서 교사와 직접 동일한 시간, 동일한 장소에서 대면하지 않고도 의사소통하고 교수-학습이 이루어질 수 있는 기회가 사회적으로 가능해지고 있다. 이러한 원격교육은 교사의 안내에 따른 탐구 교수 형태의 개념 확인 및 검증 실험이 대부분인 전통적 과학학습 방법과 달리 학생 스스로 문제를 찾고 해결하려고 시도하는 것을 통하여 과학적 탐구 기능의 향상은 물론 과학적 개념의 획득, 과학, 사회, 기술에 대한 폭넓은 인식을 형성하는데 도움이 된다. 또한 인터넷 환경을 이용하면 학교 실험실 상황을 벗어나 학생들에게 다양한 탐구 활동 기회를 제공할 수 있고, 또한 그에 따른 의사 소통이 더 용이해질 수 있다. 이에 따라서 본 연구에서는 탐구 과정기술과 사고력을 중시하는 초등학교 과학과목의 특성을 고려하여 이에 적합한 인터넷 원격교수-학습을 위한 교수-학습 모형과 학생들의 과학적 탐구력과 사고력을 신장시킬 수 있는 멀티미디어 학습자료를 개발하고, 이를 실제적으로 적용할 수 있는 웹사이트를 개발, 현장에 적용하여 원격교수학습이 과학적 탐구력과 사고력에 미치는 효과에 대하여 조사하였다.
