Nowadays, the importance of presentations is emphasized more and more. But the university presentation education has not met the today's needs. So this study is focused on showing effective practice methods and finding development directions of the university presentation education, by having a correct understanding of presentation as a process of convergence communication. To accomplish purpose of study, I analyzed and criticized the case of Writing and Communication classes at Seoul National University of Science and Technology which has carried out practical presentation education based on former learners presentation outcomes. As a result, I suggested actually helpful presentation education method by dividing and explaining presentation process into two stages which were 'contents planning' and 'expression&communication'. To properly actualize the university presentation education, It will have to operate as convergence program and activate more learner interactions, the communications between Instructor and learners.

In this study, a TPACK-based STEAM program was developed and applied under the theme of excretory organs in the 'Structure and Function of Our Body' of the elementary science curriculum. The program was produced and conducted through curriculum analysis and learning goal detailing, learning environment analysis, teaching·learning method and technology selection, TPACK elements arrangement and teaching·learning material development, application and effectiveness verification. Teacher's TPACK considered in STEAM program design process is content knowledge (appearance and work of excretory organs), pedagogical knowledge (STEAM, problem-based learning, research learning, discussion learning, cooperative learning, scientific writing) and technology knowledge (3D printer and smart device application technology). The program consisted of a total of 8 hours of project learning activities and was applied to 29 students in the fifth grade as an experimental group. A program of the same theme developed mainly from textbooks was applied to 27 students in the fifth grade of a comparison group. As a result of the application of the program, the experimental group showed significant improvement in creative problem-solving ability and scientific attitude compared to the comparison group, and the class satisfaction with the STEAM program was also high. However, there was no significant difference in academic achievement ability.

The present study was conducted to investigate science and engineering graduate students' proficiency in technical English writing and their perceptions of research ethics. Given that graduate students in science and engineering colleges usually write journal articles as well as dissertations in English, this study examined their experience of and preparation for technical English writing, writing practices, and research ethics including plagiarism. The results of the study show that it is very necessary to intensify education on research ethics and to provide educational training in proper citation practices. These findings can be used as a basis for the development of future academic curricula and other support resources to improve science and engineering graduate students' technical English writing.

This study analyzed what STEAM elements, except mathematical content, are contained in 2009 revised elementary school 5th and 6th grade group mathematics textbooks. STEAM elements in the textbooks were examined by grade and by content area in the elementary school mathematics curriculum. The results were as follows. First, the number of STEAM elements in mathematics 5-1, 5-2, 6-1, 6-2 are 151(18.4%), 212(25.9%), 211(25.7%), 246(30.0%), respectively. The 6th Grade than in 5th Grade can be seen a few plenty. Second, the number of STEAM elements are different depending on the type of STEAM. The number of arts element is 617(75.2%) and this elements are seen the most. The number of representative art and cultural art is 445(54.3%) and 172(20.9%), respectively. The number of technology-engineering and science is 158(19.2%) and 45(5.5%), respectively. We need to developed to promote use of science element in next mathematics curriculum.

This study analyzed what STEAM elements, except mathematical content, are contained in 2009 revised elementary school 3rd and 4th grade group mathematics textbooks. STEAM elements in the textbooks were examined by grade and by content area in the elementary school mathematics curriculum. According to the results, the difference between 3rd and 4th grade in the number of STEAM elements is almost not visible. Distribution of specific content areas could be seen that the distribution STEAM element is similar to the percentage distribution of the content area. However, the number of STEAM elements are different depending on the type of STEAM. The number of arts element is 448(67.6%) and this elements are seen the most. The number of representative art and cultural art is 344(51.9%) and 104(15.7%), respectively. The number of technology-engineering and science is 160(24.1%) and 55(8.3%), respectively. We need to developed to promote use of science element in next mathematics curriculum.
