One of the problems with testing for the presence of $CO_2$ is that the results are not visible. In order to over-come this weak point, a new testing method was developed with BTB indicator equipment, that made the gas visible. After that, the experiment was performed and tested the effects of the new visible equipment. The visible equipment could be adapted to regular class use successfully. Also, it was effective in that it reduced waste of gas, minimized danger potential through use of $CO_2$ canisters and candle-sticks, and also increased knowledge about indicators. The new experimental method and equipment affected the students' interest. It is possible that the students' positive participation was due to their interest in the new apparatus and application of the visual senses. The new system was tested fer its effects on teaching content and helping to produce sustained memory of the content. There were no significant differences between the groups in terms of content learning on initial content memory. However, when students in both groups were tested 4 months later, the visual experiment group sustained memory performance, while the other group showed a significant decrease. Generally, boys score higher than girls in terms of interest and participation in experimental activities. In this case, however, there were no difference between groups. It may have been due to introduction of new equipment and different methods from the textbooks. So, this could increase participation in science using various experiments.

The variety of learners include students with disabilities and general students, and an ongoing focus of inclusive education research is non-discrimination. As part of integrated education, UDL (Universal Design for Learning) for students with disabilities supports a practical approach, participation, and advancement to improve learning opportunities for all students. The purpose of this study was to examine the effects of using UDL in science classes. The dependent variables of this study were academic achievement in science, scientific attitude, and scientific motivation. In this study, the experimental groups were 9 people in the 5th grade and 11 people in 6th grade. The experimental groups were taught science class using UDL. In order to analyze the learning outcomes, the structure equation model was performed. The results of this study were as follows: First, the science achievement of learning outcomes of the science class applying UDL directly affected both scientific attitude and scientific motivation. Second, the scientific attitude of learning outcomes of the science class applying UDL directly did not affect scientific motivation. According to these results, learning outcomes for science achievement of the science class applying UDL showed that UDL affected both general students and students with disabilities. To summarize the analysis of learning outcomes, science achievement directly affected both scientific attitude and scientific motivation while scientific attitude did not affect scientific motivation. This study offered a specific implementation method for integrated education. Using the structure equation model for analyzing the effect has more significance.

The purpose of this study was to analyze the character of the creative design processes that appear at the creative design stage of the design thinking based on STEAM class and what factors affect the creative design process. Students who served as the subjects of this study were 4 elementary school students. We developed the design thinking based on STEAM program to look more specific the creative design process. The project was conducted with a total of 12 sheets of paper materials. The conclusions of this study are as follows. First, the problem solving process of the design thinking based on STEAM classes is not anticipatory and is cyclical and complex. So, teachers should provide sufficient time for students to create and simulate ideas and accept the solving problems through trial and error. Second, Having presented the STEAM class as a practical problem in the real world, there was less fear of students' failure and heightened motivation and enthusiasm. Providing with the real topic and open questions in classrooms can lead to students' voluntary participation in the classroom. Third, In the design thinking based on STEAM class, students develop concrete ideas through visualization courses. The group of students made the best solutions through communication.

Since the high throughput for diffuse objects and the wide-area survey even with a small telescope can be achieved in space, infrared (IR) obervations have been tried through small missions in Korea. Based upon the previous technical development for infrared spectro-photometric instrument, NISS (Near-infrared Imaging Spectrometer for Star formation history) onboard NEXTSat-1, we participated in the all-sky infrared spectro-photometric survey mission, SPHEREx. The SPEHREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) was selected as the NASA MIDEX (Medium-class Explorer) mission (PI Institute: Caltech) in this February. As an international partner, KASI will take part in the hardware development, the operation and the science for the SPHEREx. The SPHEREx will perform the first all-sky infrared spectro-photometric survey to probe the origin of our Universe, to explore the origin and evolution of galaxies, and to explore whether planets around other stars could harbor life. For the purpose of the all-sky survey, the SPHEREx is designed to have a wide FoV of 3.5 × 11.3 deg. as well as wide spectral range from 0.75 to 5.0㎛. Here, we report the status of the SPHEREx project and the progress in the Korean participation.

본 연구는 김제시 1개 중학교 2학년 여학생 5개반을 연구 대상으로 협동학습 실시 전 과학 선호도에 대한 사전 검사를 실시하였다. 약 10주간의 실험 처치를 한 후 사전 검사와 동일한 검사지로 사후 검사를 실시한 결과 여중생들의 과학적 선호도에 긍정적인 효과가 나타났다. 과학 수업에 대한 인식과 과학 수업에 대한 참여도가 협동학습 전과 달리 긍정적인 변화를 보였다. 그러나 과학자들에 대한 인식이나 과학적으로 사고하거나 행동하는 습관을 나타내는 과학적 태도는 유의미한 차이가 없었다. 이는 10주 동안의 기간은 협동학습 전략을 효과적으로 시행하는데 충분하지 못한 것으로 생각된다. 협동학습에 대한 학생들의 의견 조사서에서 중위 수준 학생들은 상-하위 수준 학생들과 달리 협동학습에 대해 강한 긍정을 나타냈다. 협동학습을 통해 상위 수준 학생들에게 배우고, 하위 수준 학생들에게 나누는 모둠 활동에서 자신감을 얻고 흥미를 느낀 것으로 본다.

In this study, we summarized and analyzed domestic research papers including science-related attitude in science education over the past 30 years, mainly teaching & learning methods. We reviewed 240 papers of experimental design in Journal of the Korean Association for Research in Science Education and Journal of Korean Elementary Science Education until the last volume of 2014 with results of statistical significance. The results are that students preferred group compensation rather than individual compensation. Also, students' active participation in class activities were effective in promoting students' science-related attitude. On the other hand, students' attitudes related to science did not show significant effectiveness in science class focusing on conceptual understanding. The results of this study regarding the positive or negative influence of teaching & learning methods in science will be expected to be useful when science teacher makes a selection the proper teaching methods.
