In order to cultivate talented people with national economic influence in the rapidly changing 21st- century modern society, STEM(Science Technology Engineering Mathematics) education has been emphasized in advanced countries such as America and England. In South Korea, STEAM(Science Technology Engineering Arts Mathematics) education is emphasized by adding Arts. The objective of STEAM education is to strengthen the interest and motivation of learners, to focus on experience, exploration, experimentation, to solve convergent thinking and real-life problems, rather than cramming method of teaching and memorization. This study identifiesan instructional design for converged English, the world's official language, and science which is found in nearly all disciplines. With the development of the 4th industrial revolution based on the PBL model, learners participate in their lessons voluntarily for problem-solving skills. The instructional design based on the ADDIE model consists of 5 procedures: Analysis, Design, Development, Implementation, and Evaluation. The goal of fostering talented people with national economic influence is also important, and the teacher in education must recognize the importance of STEAM education and an appropriate instructional design should be studied constantly.

Despite the growing importance of socio-scientific issues (SSI), little work has focused on teachers' pedagogical knowledge, and few studies have examined how in-service teachers use and apply SSI-related instructional methods and strategies. Consequently, the purpose of this study was to explore how science teachers with lots of SSI teaching experience determined teaching orientation, selected and revised instructional methods, and devised assessments in science classroom. We used a case study approach aimed at a deep description of these teachers' teaching experiences and employed semi-structured and in-depth interviews with five experienced teachers. Our findings indicate that teaching orientation and learning objectives seemed to influence the selection and modification of instructional strategies and methods. In addition, students' learning experiences or classroom environment were considered and modified in light of achieving these learning objectives. However, introducing SSI into the classroom assessment is not seriously considered by most teachers. This study can provide teachers with useful information when designing and developing SSI classes, taking into account various aspects of the PCK such as learning orientation, instructional methods, learner expereince and curriculum standards.

This study is to design, develope, and deploy of e-learning inquiry based content in elementary science class. First, this study analyzed related literature review, case studies, and inquiry based class models for seeking better applicable design and development modes. From focus group meeting, experts discussed the inquiry content design ideas for elementary students for science class. This study finally established its own inquiry design mode for online science class with the flow of understanding of problem, sep up hypothesis, problem solving, and solution analysis. The developed content was deployed in real classroom setting to see how students received the contents and how well they processed the learning activities. We found that inquiry based online content, especially when applied to science subject, can be effective in students interests and their motivations. We also observed that there were a few managerial errors such as detailed lesson guidance and tutor support for students activities. This study concluded that inquiry based online contents should be designed considering students interests based on learning subjects and also developed in terms of students interests and strong motivation as well. We suggest that related research should be expanded toward to other subject than science and various students age groups.

Digital textbooks enable learning that is appropriate to the characteristics and level of learners through various interactions. The purpose of this study was to develop an instruction model that can more effectively use digital textbooks in elementary science classes and to verify its effectiveness. The results were as follows. The instruction model for helping learners complete their learning by using digital textbooks needs to receive diagnostic assessment and feedback on entry behavior, to build a self-directed learning environment, and to interact with teachers, students, and digital textbooks as scaffolding. In this study, we developed an instruction model using digital textbooks reflecting these characteristic. The instructional model consists of preparation, practice and solidity step. In the preparation step, the learner performs a diagnostic evaluation using digital textbooks. Based on the results, feedback provided at each level can complement the entry behavior and maintain interest in learning activities. In the practice step, self-directed learning is implemented using diverse functions of digital textbooks and various types of data. In the solidity step, learners can internalize the learning contents by reviewing video clips which are provided by teachers, performing problem-solving activities, and accessing outcomes accumulated by learners in the community online. In order to verify the effectiveness of this model, we selected the "Weather and our Life" unit. This experiment was conducted using 101 students in the 5th grade in B Elementary School in Gwangju Metropolitan City. In the experimental group, 50 students learned using a smart device that embodies digital textbooks applied with the instruction model. In the comparative group, 51 students were taught using the paper textbooks. The results were as follows. First, there was a significant effect on the improvement of the learning achievement in the experimental group with low academic ability compared with the comparative group with low academic ability. Second, there was a significant effect on self-directed learning attitude in the experimental group. Third, in the experimental group, the number of interactions with the learner, teacher, and digital textbook was higher than the comparative group. In conclusion, the digital textbooks based on the instruction model in elementary science classes developed in this study helped to improve learners' learning achievement and self-directed learning attitudes.

This study is to investigate how science and engineering integrated (SEI) lessons affect science-gifted students' perceptions about engineers and engineering practices. Twenty elementary science gifted students participate in this study, and they reflect what engineering practice means such as managing limited time and budget. The SEI lessons with 24 hours class time are used as an intervention. The main data are collected with 'engineer and engineering drawing test', open-ended questions and interviews about the drawing, and focus group interviews about the lessons. The transcribed interview data are analyzed using mixed methodology of quantitative (descriptive and paired t-test) and qualitative methods. The result shows that the SEI lessons have positive impacts on the science-gifted students' perceptions about engineers and engineering practices such as engineering design. After the lessons, the students perceive engineering and engineers in a desired way such as engineering as a social practice that many experts work collaboratively, the interaction between engineering and society, and the importance of ethics and social values in engineering practice.
