For heat-assisted magnetic recording, magnetization reversal probabilities of nano-Pt/MnSb multilayer film with perpendicular magnetic anisotropy under thermal pulse activation were investigated numerically by solving the Landau-Lifshift Gilbert Equation. Magnetic parameters of nano-Pt/MnSb multilayer were used with anisotropy energy of $3{\times}10^5$ erg/cc and saturation magnetization of 2100 G, which offer more than 10 y data stability at room temperature. Scheme of driven magnetic field and thermal pulse on writing mechanism was designed closely to real experiment. This study found that the chosen material is potential to be used as a high density magnetic storage that requires low writing field less than two-hundreds Oersted through definite heating and cooling interval. The possibility of writing data with a zero driven magnetic field also became an important result. Further study is recommended on the thickness of media and thermal pulse design as the essential parameters of the reversal magnetization.

This paper analyzed the discourse on writing by experts such as writers, novelists, and writing instructors appearing in YouTube videos through narrative analysis methods. According to the analysis, the five key topics comprising writing discourse were: Active reading for writing, Nonstop writing and writing more, Rewriting 10 times more than talent, Writing in spoken language in the era of one-person media, Sharing feedback on social media. The writing discourse of professionals illustrated the change in writing in the age of social media. First, it was confirmed that the writing culture shifted from reading to writing and rewriting. Second, writing in the social media era naturally showed that the spoken language of writing became the dominant code. Third, it has been confirmed that writing in the social media era is social writing of cooperation and sharing that openly share feedback. These findings will have significant implications for future research on media and writing

The present writers have raised some basic questions related to writing. Do the theses produced in the library and information science field tell our story\ulcorner Are they field-oriented\ulcorner Are they easy to be read and to be a n.0, pplied by the librarians\ulcorner Problems in writing include research theme, research method and writing style. The present writers have a n.0, pplied phenomenological a n.0, pproach to these problems, using the observation of 'Co-workers Team' and interpretation of the 'Term Paper Collection'(vol.1-vol.5). Co-workers Team members consist of professors and graduate students in the Department of Library, Archives and Information Studies of the Pusan National University. We have made some proposals in this paper: First, we should not talk about American story. We should talk about our own story, and go back to basic themes. This proposal is related to the innovation of research theme. Second, qualitative research method should be introduced extensively in library and information science. Third, the strict 'thesis-oriented' and 'text-oriented' writing style should be overcome. The prevalent writing style in our field is so uniform that they are not capable of describing the intricate problems like "our living library".ary".uot;.

The purpose of this study was to investigate the elementary school teachers' perception of science writing. In this study, 10 elementary school teachers who have taught in the 3rd or 4th grade science lesson in 2010 were selected. Researchers constructed interview guide in three parts including the teachers' understanding of science writing, the status of science writing teaching and the difficulties of science writing in their classes. For the investigation, semi-structured in-depth interviews with 10 elementary school teachers were conducted individually. The results showed that the elementary school teachers were unfamiliar with the word ‘science writing’ and considered science writing as a writing using science learning contents. Also, they think that teaching science writing in their science lessons was not needed and didn't assess and provide detailed feedback with the students' written works. Most teachers needed teaching materials and assessment tools for science writing. To develop elementary teachers' understanding of the value and use of writing for learning in science, they will need to participate in science writing programs for in-service teachers and various teaching materials and assessment tools should also be developed.

EMI (English as a Medium of Instruction) classes are now accepted policy at Korean universities, yet students often struggle with required academic English writings. The present study examined an EMI class that used direct instruction and access to online assistive English writing software. From preliminary analysis, 26 students expressed interest in how an EMI academic writing class could facilitate improved English writing skills. Study participants completed a survey on self-efficacy and learning needs and assignments for an EMI academic writing class. To establish inter-rater reliability, three trained raters assessed the written essays of students prior to and after instructional intervention. Fleiss' Kappas statistics showed moderate reliability. Students' opinions on the use of online software were also analysed. Paired t-test was run on the quality of students' pre- and post-instruction assignments, and there was significant difference in the rated scores. Self-efficacy was found to have moderate positive association with improved post-essay writing scores.

In this study, we investigated the writing process components and the writing strategies that appeared in the process of argumentative writing through students' think-alouds and semi-structured interviews. The subjects were 18 eighth graders. During argumentative writing, students were asked to decide whether they agreed with the given argument or not on the basis of information provided in the writing task. We categorized the writing process components and the writing strategies by analyzing the protocols of students' think-alouds and interviews, and evaluated the level of their written compositions. The analyses of the results indicated that the writing process components of argumentative writing showed different characteristics from those of problem solving writing in several components such as setting goals, organizing an outline, and evaluating content. In addition, the writing process component 'coordinating information' was newly discovered in argumentative writing. The writing strategies were categorized into four groups by the types of decision making (reflective/intuitive) and the existence of outline organization: Reflective decision making and outline organization, reflective decision making and no outline organization, intuitive decision making and outline organization, and intuitive decision making and no outline organization. Students with the reflective decision making and outline organization strategy were found to get the highest scores in written composition in terms of the relationship between the argument and its grounds, the rebuttal of the opposing argument, and the structure of the writing. Educational implications are discussed.

The purpose of this study was to examine the science writing and perception of students who experienced the argument-based claim and evidence writing approach. One hundred and eight grade 11 students were assigned to an experimental group, while 99 grade 12 students were assigned to a comparative group in their earth science classes. Students' science writings on two science topics were scored using an analytic rubric developed in this study. The comparison of experimental and comparative groups in science writing was carried out using an independent two samples t-test. Students' perception on the instruction was examined using an open-ended survey. Science writing by the experimental group scored significantly higher than that by the comparative group, except for the big idea of 'green energy'. For six concepts in 'green energy' and four concepts in 'plate tectonics, there were more students in the experimental group than the comparative group who indicated them in their science writing. Students' perception on the instruction was positive in that they mentioned planning and conducting inquiry, citing of claims and evidence, and developing inquiry questions were helpful in science learning. The results of this study imply that the argument-based claim and evidence writing approach should be implemented in science classrooms for students to develop a conceptual framework for science.

The purpose of this study was to investigate the effects of the Science Writing Heuristic (SWH) approach on the students' summary writing, logical thinking and achievements for the course. Participants in this study were 132 female students from a girls' middle school. The SWH approach was used for two experimental classes and the typical teacher-centered instructional approach was used for two comparative classes. Summary writing test, logical thinking test (GALT) and achievement test for the course were administered before and after the instruction period. Results of this study indicated that the SWH approach was helpful for students in finding big ideas, understanding science concepts, developing logical thinking abilities and doing well in the course. This study also implied that the SWH approach was effective for the low achieving students.

It has been recently emphasized that comprehensive understanding of students' cognitive activities in the process of writing as well as final product is needed in order to develop an effective strategy for science writing. In this study, we investigated the characteristics of writing process in the situation that students wrote a composition in solving the application problem on a science topic. Seven eighth graders selected in the consideration of their science achievement and communication skills were asked to write a composition using think-aloud method. They were also interviewed after their writing work. The analyses of the results indicated that students' writing processes consisted of six distinctive components: generating, organizing, setting, translating, evaluating, and revising. It was also found that the patterns of process components for each student were different in terms of the frequency and the sequence. The patterns of process components were categorized into four types: systematic, tacit planning, trial and error, and random strategies. Educational implications were also discussed.

In this study, the researcher aimed to increase productive reflection of pre-service elementary teachers through reflective journal writing and discussion after science peer teaching practice. 'Productive reflection' involves consideration and analysis of interrelationships among aspects of teaching including learners and learning, subject matter knowledge, assessment, and instruction. During 8 week efforts, productive reflection has increased gradually in both individual journal and class discussion. However half of individual journals didn't show productive reflection even in the final stage. This implicated that development of reflective thinking is an achievable but progressive change. By describing the progress in discussion and participants' responses on journal writing and discussion activity, this study shed light on practical ways of enhancing reflective teacher education.
