The purpose of this study was to examine the effects of experimental learning using the small-scale chemistry (SSC) on high school students' academic achievement, scientific attitude and science-related attitude in high school chemistry I. For this study, two high school 2nd grade classes were divided into an experimental group and a control group. Experimental learning using the SSC in the experimental group, traditional experimental learning presented in the textbook in the control group were performed. The results showed that experimental learning using the SSC compared to traditional experimental learning was effective in improving academic achievement. The experimental learning also was effective in improving voluntary, patience, cooperativity in the scientific attitudes and social implications of science, attitude for science curriculum, attitude toward science in the science-related attitudes. Therefore, experimental learning using the SSC is necessary to actively utilize in high school chemistry curriculum.

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.

The aim of this study was to compare the effectiveness of microcomputer-based laboratory (MBL) with the traditional laboratory experiment on science classes in middle school. MBL tools were developed and applied for five experiment subjects chosen from middle school science textbook for MBL experiment classes, while usual experiment methods suggested in the textbook were used in traditional experiment classes. In order to evaluate the effects of MBL experiment class, achievement, graphic ability, science process skills, affective aspect related to science were tested before and after applying the MBL experiment. The result revealed that MBL experiment class was more effective than traditional experiment class in improving student's science achievement, science process skills, and graphic ability. The result also indicated that there was a significant difference between experiment and control group with regards to the effect on affective aspect related to science. From the above result, we can find the positive implication of applicability of MBL experiment as a new experiment tool at the early stage of introduction in a real context.

Two biology modules were developed previously for the purpose of improving creativity and scientific thinking of secondary school students. A hypothetical-deductive experimental procedure was reflected in the module when students themselves can perform a series of activities of making hypothesis and designing an experiment to solve the questions. They followed a series of scientific processes to determine some characteristics regarding plant pigments and the transport process of materials in living organisms. Four classes of 9th graders in'S' Science High School were divided into the experimental and the control group. The same contents of the modules were taught to the control group by the traditional experimental way. The students' creativity, scientific thinking, scientific inquiry skill and knowledge achievement were examined before and after the interventions. As results, the experimental groups showed more significant improvement on the areas of the students' creativity, scientific thinking, scientific inquiry skill and achievement than the control groups. Results indicated that the specially designed modules in terms of hypothetical-deductive experimental procedure were effective to improve science high school students' creativity and scientific thinking abilities.

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.

근래에 많은 형질전환 실험동물이 생산되어 인간을 대체하여 전임상실험에 사용되고 있으며, 그 요구는 점차 증가되고 있다. 그러나 지금까지 생산된 것은 소형 실험동물에 국한되고 있어, 사람과의 그 크기와 기능에 거리가 있었던 것이 사실이다. 본 실험은 중형 실험동물이자 사람과 여러 기관 및 조직이 유사하다고 알려진 돼지로부터 난자를 채취하여 난자의 핵을 GFP가 발현된 세포의 핵으로 치환하여 태어난 산자를 재복제하여 생산된 돼지 신생자를 이용하여 각 기관 및 조직에서 GFP의 발현을 RT-PCR, Northern blot 및 immunocytochemistry 방법으로 분석하였다.

The purpose of this study was to find out the factor that causes the difference on understanding the aim and perception of laboratory activities between teachers and students. For this study, in-depth interview was conducted for sixth grade students and teachers of 10 classes. The questionnaire of the interview can be divided into 3 sections: the aim of laboratory activities, whether teachers present the aim of laboratory activities, the method of laboratory class progress and the evaluation method. The factors that bring about the difference between the teachers and the students on perception of the aim are the absence of proper guidance on the aim of laboratory activities, the laboratory classes that the progress out of teachers' intention and evaluation method that is the performed without any relationship with the aim of the laboratory activities. Because the teacher-intended aim of laboratory activities is not properly presented, students can't percept the accurate aim. Even though teachers recognize the importance of the improvement of science process skill acquired through laboratory activities, this is not delivered practically in the class and students also can't percept the importance of science process skill.
