  • 대개 학교에서 이루어지는 과학 실험은 추상적인 과학 지식이 실제에 어떻게 적용되는지를 보여주기 위한 것이다. 그러나 많은 경우 학습자들은 실험을 하더라도 그 실험이 어떤 의미를 가지고 있는지 이해하지 못한다. 이 연구는 초등 예비교사를 대상으로 하였으며 실험 활동과 관련된 과학사를 연극의 형태로 도입하여 실험 내용에 대한 이해를 증진시키고자 하였다. 먼저 전자기 유도에 관련된 몇 개의 실험을 실시한 후 패러데이의 전자기 유도 발견에 관한 짧은 과학 연극을 준비하고 실시하였다. 그리고 이러한 과학 연극의 도입이 이전에 실시한 실험 내용(실험 결과와 이에 대한 해석)을 이해하는데 도움이 되는지를 알아보기 위해 실험 직후, 과학 연극 실시 직후 동일 검사지를 실시하여 비교 분석하였다. 또한 과학 연극을 실시하는 것이 과학 학습에 도움을 주는지에 대한 예비교사들의 의견도 설문을 통해 조사하였다. 연구 결과 과학 연극을 실시한 직후 이전에 실시한 실험의 내용을 이해하고 그 실험으로부터 얻은 지식을 적용하는 능력이 향상된 것으로 나타났다. 연극 공연자가 관람자에 비해 실험에 대한 이해가 더 많이 증가하였지만 통계적으로는 유의미한 차이가 없었다. 또한 80% 이상의 참여자가 과학 연극이 실험 내용의 이해에 도움이 되는 것으로 안식하였으며 공연자가 관람자보다 더 긍정적으로 인식하였다. 참여자들의 반응으로부터 어떠한 점에서 과학 연극이 과학 학습에 도움이 되는지, 과학 연극의 장점과 한계점이 논의되었다.

  • In this study, pre-service science teachers' reflective thinking in their journal writing was investigated. To do this, the authors used pre-service science teachers' journal writing abilities, wherein they not only reported data and result formally, but also wrote their feelings and reflections about an inquiry-based physics experiment they performed. Pre-service science teachers' writings were decomposed into sentences and each sentence was analyzed into a framework with 4 dimensions: knowledge, procedure, orientation and attitude. Reflective thinking in knowledge dimension included reflection on what they know before the experiment, what they still do not know and what they learned from the experiment. Reflective thinking in procedure dimension included recalls of experiences about general experimental procedures and specific experimental skill. Reflective thinking in orientation dimension included their views about the nature of science and science teaching and learning, and reflective thinking in attitude dimension consisted of interests, motives and values about the experiment they performed. While there were some variations in frequency distribution of reflective thinking by the topic of experiments, pre-service science teachers' reflective thinking in journal writings revealed their metacognition on their knowledge and learning, epistemological belief about science and science learning, and affective domain related to experiment. This study can infer that such kind of writing with 'their own language' in an informal way followed by formal 'scientific' reports in a scientific experiment has a significance not only as a mediator representing reflective thinking but also as an instructional activity to facilitate reflective thinking in science learning and teaching.

  • The purpose of this study was to investigate the middle science teachers' perceptions on science lessons with experiments. The study conducted a survey for 110 science teachers participating in inservice program. The middle school science teachers taught classes with lectures rather than with experimental activities. They had an experiment one to three times a semester in their lessons. They did an experiment to follow to what the textbook said, or to confirm it, like a cookbook style. The most teachers answered that they had over average ability to teach both lecture and experiment. Through the experiment, they expected students had interests and curiosity on science. Despite the advantages of experiments, there were many constraints to conduct experiments, such as teachers' excessive work, laboratory conditions, education environment, and others. It was demanded on continuous interest and investment in the variation of educational environment so that teachers can experiment more often.

  • 현대 교육은 단순한 암기 위주가 아닌 첨단 컴퓨터를 이용한 실험 실습 위주의 직접 보고 듣고 느끼는 방향으로 진보하고 있다. 실험 실습에 의한 과학교육은 사용자의 탐구능력 향상과 과학적 태도 향상에 중요한 역할을 하게 될 것이며 기존의 암기위주나 단순한 수치에 의한 개념 학습을 탈피하여 Data collection 기술과 분석의 활용을 통해 사용자가 과학을 좀 더 이해하고 사용할 수 있도록 하는 능력을 증진하게 한다. 이를 위한 과학교육의 한 방법으로 MBL(Microcomputer Based Laboratory)은 실험자가 실험실이나 야외에서 각종 기구를 사용해 데이터를 습득할 수 있도록 도와주는 컴퓨터 기반 과학 실험 시스템으로서 미국, 영국 등 과학 교육 분야에서 추구하고 있는 세계적인 추세라고 할 수 있다. 이러한 MBL 시스템의 구성은 센서를 통해 얻어지는 자료를 컴퓨터에 전달하는 매개체인 인터페이스, 과학 실험에서 발생하는 데이터를 직접 전기적 신호로 변환하여 인터페이스에 전달하는 센서, 인터페이스에서 전달되는 전기적 신호를 컴퓨터 화면에 나타내어 주는 컴퓨터용 전용 프로그램으로 구성된다. 이러한 MBL을 과학교육에 활용한다면 학생들이 스스로 과학적으로 탐구하고 문제를 해결할 수 있는 능력을 배양하는 데 많은 도움이 될 것이다.

  • As the 2015 revised curriculum is being implemented from 2018, efforts are being made to cultivate scientific literacy among students in the field of science. Scientific experiments help students to develop their interest in Science and their scientific attitudes. Learning through experimentation rather than learning scientific facts increases learners' understanding, and can be remembered longer. Therefore, experiments in Science subject are very important. However, in middle schools, scientific experiments are not performed due to the lack of time, budget and experimental material. In this research, we analyze middle school science textbooks, conduct questionnaires for students of science pre-service teachers, select the most important science experiments, and develop a mobile App to simulate and experience scientific experiments with the App. The proposed App is developed in a game format using quest-based learning methods to gain learning enhancement. It is also made using Unity. In this paper, after developing the app, we propose the direction of STEAM contents development through analyzing the difference from existing apps and the feedback from users.

  • This study was to find science high school students' perception about composing laboratory reports by grade. The instrument to survey the perception of them consisted of the perception about making a lab report, and the effect of compositing laboratory reports on the scientific concept understanding and the scientific inquiry ability. Subjects were 260 students of four science high schools in Seoul metropolitan city and Kyounggi province. Most of science high school students had a little positive perception about compositing lab reports, but they had very positive perception about the effects of it on the scientific concept understanding and scientific inquiry ability. There was the significant difference between grades, because the 10th grade students showed more positive perception toward compositing lab reports than the 11th graders(p<.05). The results suggested that different educational approaches and teaching strategies be needed for science high school students considering grades.

  • The purpose of this study was to examine the effects of experimental learning using Small-Scale Chemistry (SSC) on science achievement and scientific attitude of high school students. SSC experiments were devised for 5 experiment themes of high school science textbook. Two classes were chosen from a high school in Busan and adopted into the comparison group and the experimental group; one group with thirty-four students participated in the class with an experimental learning using the SSC (experimental group), and another group with thirty-seven students participated in the class with the traditional learning (comparison group). The major discoveries of this study were as follows: Experimental learning using SSC has shown a significant difference between two groups in the science achievement of the students. Also there was a statistical difference between these two groups in the test which was conducted after a month to find out the durability of the experiment. Thus, the learning using SSC is assumed to be durable. Furthermore, there was a significant difference in scientific attitude between the two groups. It seemed that the learning using SSC had a good influence on fanning students' scientific attitude. In conclusion, an experimental learning using SSC has a positive effect on scientific achievement, the durability and scientific attitude of the students. We hope to develop suitable and various experimental learning materials using the SSC program that can be adopted in the classroom soon.

  • Experiment is recognized as an important part in science and science education. Scientists do experiments for verifying or refuting theory and they take many forms to do experiments. One of the central goals of science education is to improve inquiry ability. So we have taken for granted that students engage in authentic inquiry and experiment which scientists carry out to research. But it is not always positive about discussions and opinions what school experiment and its role is in learning science and understanding about science. There is certainly a gap between experiments which scientists and students do even though there is a theoretical basis of school science experiment. In this study, we discussed how scientific inquiry and school inquiry are different, and what it means to use instrument in school science experiment. And as a case, we analyzed chemistry experiments in science textbook and manipulation level of instruments which were handled in chemistry experiments, we shed light on the meanings of experiments and instruments in school science inquiry based on the result of experiments and instruments analysis.

  • 과학과 정보통신 관련 기술 교육은 그 교육적 잠재력이 무한하고 이에 따른 열의 또한 높아지고 있다. 그러나 기초과학 교육의 산실이라 할 수 있는 초등학교 과학 실험 환경은 매우 열악하여 학생들은 각종 위험 상황에 노출되어 있고 교사들은 학생들을 각종 안전사고에서 보호하기 위해 실험 환경을 과도하게 통제하게 되어 학생들은 기본적인 활동에 상당한 제약을 받아 과학에 대한 의욕과 흥미가 저하되는 문제가 발생하게 되었다. 본 연구에서는 이러한 문제점들을 해결하기 위하여 최근 유비쿼터스(Ubiquitous)컴퓨팅 기술로 주목을 받고 있는 RFID(Radio Frequency IDentification) 기술을 이용하여 실험 약품에 고유의 전자태그를 부여하고 Mobile RFID 리더기가 장착된 PDA를 이용하여 약품의 개별 정보와 관련 과학실험 방법을 비롯하여 실시간으로 안전교육을 받을 수 있는 시스템을 통해 안전 조건이 미비한 실험실의 물리적 환경 개선을 통해 보다 능률적이고 심도 있는 과학 실험 환경을 구축할 수 있는 시스템을 설계하였다.
