In this research, a subject substitute STEAM program was developed in context of a trend of STEAM education and a new science contents in a 2009 revised curriculum, which can replace the 2009 revised curriculum contents of 'Sound' unit in the third and the fourth grade. The developed program was taught to the 4th graders in a field. After applying the program, how students acknowledge the subject substitute STEAM program was analyzed through questionnaire. The research results were as follows. First, the subject substitute STEAM program of 3 sub programs was developed with centered around 'sound' unit for 4th graders. Second, students made a positive estimation of the STEAM program because of various activities and learning subject related to daily life. Third, they considered difficult term, necessary craft skills in creative design, understanding scientific principle and a lot of necessary time as difficulties of the STEAM program. And they also recognized that making stuff activity and learning aid material like activity sheet, picture and video helped to understand a lesson. Lastly, students had a positive thinking or negative thinking about STEAM program before they learn. But after learning the STEAM program, all of them showed their positive attitude to the STEAM program.

The primary purpose of the study was to investigate the degree of difficulty and the causes of the difficulties in science instruction reported by elementary teachers and students. The secondary purpose was to suggest the effective methods to both of them to improve the efficiency of science instruction. For this study, the survey was carried out on 322 students and 156 teachers in the 3rd, 4th, and 5th grades. The questionnaires consisted of interest, difficulty and its factors. The results of this investigation are summarized as follows; 1. Teachers had relatively higher interest than students in science instruction content(textbook). Furthermore, the units that teachers showed interest differed from those that students had. This means that there is a significant difference of interest in instruction process between teachers and students. 2. Teachers felt much higher difficulty than students in the content of science instruction. This shows that the degree of interest might have little relation with that of difficulty, and that teaching of science seemed more difficult than teaming. Moreover, there was a difference of difficulty in the units between the teachers and students. The result shows a distinctive difference of difficulty in 8 units of the 3rd grade, 9 units n the 4th grade, and 12 units in the 5th grade (p<.05, p<.001, p<.005, respectively). It means that the difficulty depended on the units. 3. Students responded that they are responsible for difficulty factors of teaming, otherwise teachers thought that students are responsible for it, when the factors were divided into student factor, teacher factor, and curriculum factor. 4. Students demanded many experiments in the lab as well as easy and interesting instructions in order to reduce the degree of difficulty and to improve the condition of science instructions. However, teachers demanded the expansion of experimental equipments and materials as well as the improvement of the lab condition.

Currently, many universities are implementing software-oriented universities and artificial intelligence-oriented universities to foster software-oriented manpower. We are educating students to design and produce computational thinking and coding directly with their major knowledge. However, computer education is not easy for non-majors, and there are many difficulties in coding. The results of responses from 104 students from the College of Health Sciences and College of Social Management who took the liberal arts computer at University H were analyzed using SPSS 26.0 version. In the liberal arts computer class for non-majors, a PJBL-based class plan was proposed. The effectiveness of PJBL-based classes was confirmed through a questionnaire for the improvement of artificial intelligence liberal arts courses. As a result, PJBL-based education showed statistically significant results in terms of satisfaction, effectiveness, and self-efficiency of classes regardless of major.

This paper is an in-depth case study to analyze integrated elementary science lesson planning and practical teaching by two teachers at an urban elementary schools. One is an experienced teacher and the other is a beginning teacher. For this study, researchers asked teachers to design 5 stages of lesson planning after sharing basic theories about the integrated science education. The first of the 5 lesson planning stages is curriculum analysis and choice of integrated science topic. The second stage is constructing the frame of integrated science lesson contents, and the third is drawing a diagram of the integrated science lesson development. The fourth stage is making a table of lesson plans, and the last stage is writing integrated science lesson plans. Then, the teachers implemented the lessons they created. They taught students one unit of science which is composed of 8 lessons. Difficulties that teachers meet during designing plans and integrated science class were analyzed. 5 staged lesson planning, video transcriptions, teacher interview about lesson planning and teaching, researchers' checklists, reports of inspection classes, teachers' self evaluation, and students interviews were used for this study. One of the significant results of this study is that both experienced and beginning teachers had many difficulties in deciding on time to teach and contents of science and other subjects, as well as selection and organization of whole topics of integrated science teaching. The beginning teacher especially had greater issues with developing definite teaching-learning strategy to conduct thoughts and views for integrated science at the whole unit and each lesson. However, the experienced teacher was using various teaching-learning strategies by utilizing integrated science teaching professionalism to develop students' integrated thinking ability during the instruction of other subjects. The outcomes of this study are that both teachers could deeply understand the need and value of integrated science education at the elementary school through planning and teaching 8 lessons, and that they could have self-confidence with development of teaching professionalism for integrated science teaching. It may be possible that this study could help the development of pre- and in-service program for improvement of integrated science teaching professionalism for elementary school teacher.

This study investigated how elementary school teachers reconstruct science curriculum and how they perceive about their experiences. In-depth interviews were conducted with four elementary school teachers who had experience in restructuring science curriculum. Two distinct types of reconstruction were found; restructuring within the subject and integrating between subjects. The teachers who were restructuring science curriculum from personal needs usually substitute, delete, add some contents or activities and change the order of unit within science subject. In contrast, the teachers who were participating in research school usually integrated science with other subjects, developing a new unit or project. The latter recognized the need of teachers' reconstruction of science curriculum more strongly and the importance of teacher's voluntary learning community in implementing the reconstruction. Though they had some difficulties in identifying students' interests and level of understanding and lack of time, all teachers valued curriculum reconstruction by relating it to teacher professional development, identity as a teacher, and job consciousness.

이 연구에서는 예비과학교사가 계획한 맥락적 NOS 수업을 PCK 관점에서 분석하였다. 서울특별시에 소재한 사범대학에서 교육과정을 모두 이수한 예비과학교사 8명이 연구에 참여하였다. 이들이 작성한 CoRe와 교수학습 지도안을 수집하고 면담을 실시하였다. 분석적 귀납법을 활용하여 수집한 자료를 분석하였다. 연구 결과, 예비교사들이 학습 목표로 선택한 NOS는 수업 주제보다는 NOS를 가르치는 맥락에 따라 다르게 나타났다. 또한 예비교사들은 NOS 학습의 가치를 잘 답변하지 못했다. 모든 예비교사가 학생들이 NOS를 잘 이해하지 못할 것을 우려하였으며, NOS를 과학 내용과 함께 다룬다는 점에서 많은 어려움을 느꼈다. 예비교사들은 학생들이 직접 실험을 하면 오차로 인해 학생들이 NOS를 배우는 데 문제가 생길 것이라고 생각하였다. 한편 예비교사들은 자신의 경험을 근거로 학생들의 NOS에 대한 선개념과 오개념을 추측하였으며, 과학 개념이나 학생의 인지 발달 단계가 NOS 학습에 영향을 미칠 것이라고 생각하기도 했다. 교수 전략 측면에서 NOS를 가르치기 위해 다양한 전략을 사용했음에도 불구하고 NOS를 명시적으로 다루지는 않는 경우가 많았다. 평가전략 측면에서도 수업에서 다루는 NOS를 평가하지 않으려는 모습이 나타났다. 이상의 결과를 바탕으로 예비교사 교육을 위한 시사점을 제안하였다.

This study analyzed the difficulties of middle school students in computer simulation of the law of large numbers through eye movement analysis. Some students did not attend to the simulation results and could not make meaningful inferences. It is observed that students keep the existing concept even though they observe the simulation results which are inconsistent with the misconceptions they have. Since probabilistic intuition influence student's thinking very strongly, it is necessary to design a task that allows students to clearly recognize the difference between their erroneous intuitions and simulation results. In addition, we could confirm through eye movements analysis that students could not make meaningful observations and inferences if too much reasoning was needed even though the simulation included a rich context. It is necessary to use visual representations such as graphs to provide immediate feedback to students, to encourage students to attend to the results in a certain intentional way to discover the underlying mathematical structure rather than simply presenting experimental data. Some students focused their attention on the visually salient feature of the experimental results and have made incorrect conclusion. The simulation should be designed so that the patterns of the experimental results that the student must discover are not visually distorted and allow the students to perform a sufficient number of simulations. Based on the results of this study, we suggested that cumulative relative frequency graph showing multiple results at the same time, and the term 'generally tends to get closer' should be used in learning of the law of large numbers. In addition, it was confirmed that eye-tracking method is a useful tool for analyzing interaction in technology-based probabilistic learning.
