  • This study aimed at categorizing preservice teachers' reflections and understanding their characteristics in reflective journal writing after microteaching. Thirty-two preservice elementary teachers joined in this study. As results, three patterns were categorized: Reflection with practice, Reflection to be practice, Reflection with suspension of judgment. 'Reflection with practice' changed the topology of science class in active. 'Reflection to be practice' had clear focus in reflection and suggested orientations to succeed in the next teaching. 'Reflection with suspension of judgment' made something fall into abeyance, because it couldn't provide an orientation for teaching. After discussing these results, implications toward preservice teacher education were explored.

  • Essay-writing, first introduced to Korean university entrance exams in 1994, is gaining its weight year by year. Especially from 1997 when Nationwide Education Reform System begins, it will be a key component of student selection criteria at Korean universities. Essay-writing's future, however, will not be that smooth unless it shows necessary validity and reliability. This study is on reliability of Essay-writing scoring, mainly from the experience of University K case. To secure solid reliability in Essay-writing scoring for the 1995 University Entrance Exam, the authors started research from the 1994 Autumn Pre-exam which was administred to potential applicants of University K following year. Total of 1,254 students took Essay-writing exam and, subsequently, their essays were graded by two professors independently. The result was not so good. The correlation between two scores was 0.27[0.54] with Cronbach alpha 0.43[0.70] for Humanity-Social Science [Natural Science-Engineering] field. So, some action for reliability improvement was inevitable. The authors considered and investigated following two alternatives. Alternative 1 [A1] : Essays are to be graded three tiems independently at the 1995 University K Entrance Exam. Scores will be given as the average of three scores. Alternative 2 [A2] : Essays are to be graded twice independently, followed by a possible third grading only if two gradings show "significant" defference. Scores are given as the third score if done or the average of first two scores otherwise.otherwise.

  • This research looks into the theory and practice of interconnections that exist between information literacy instruction(ILI) and writing instruction to gain further insights related to the development and forming of Korean ILI program. First of all, as evidenced by the ambiguity and various concepts that are possessed by the information literacy, this paper clearly indicates that the ILI cannot be achieved with a standardized set of guidelines across the board. And then, after investigating into the theories which deal mainly with the relativity to writing amongst the various ILI programs, this paper introduces precedents of Utah University, USA and Windsor University, Canada which have carried out writing instruction by actually connecting it with the ILI. Finally, this paper sounds out the possibility of connections or cooperation between writing and ILI within the scope of the Korean situation and suggests alternatives.

  • This study investigated the contribution of Korean phonological awareness to English phonological awareness and the relations of phonological awareness with reading and writing in Korean Hangul and English among Korean 5th graders. With age and vocabulary knowledge statistically controlled, Korean phonological awareness was transferred to English phonological awareness. Specifically, syllable and phoneme awareness in Korean transferred to syllable awareness in English, and Korean phoneme awareness transferred to English phoneme awareness. In addition, English phoneme awareness independently explained significant variance of reading and writing in Korean and English after controlling for age and vocabulary. Syllable awareness in Korean and English explained Hangul reading and writing, respectively. The results suggest cross-language transfer of phonological awareness that is a metalinguistic skill. Phoneme awareness is important in reading and writing in English whereas both of syllable and phoneme awareness are important in literacy of Korean.

  • This study explored the ESL college learners' perceptions on integrating reading and writing in the context of the reading-to-write composition classroom. Using the panel survey (N=60) that repeatedly measured the same set of individuals at three different times during a semester, this study examined whether students' perceptions on reading-writing integrations were reshaped over the course of classroom practices. The survey instrument was developed to assess the perception scores from less integrative continua to more integrative continua on a 5-point Likert scale. A two-factor ANOVA with repeated measures was performed to evaluate mean differences across the perception groups and over the three treatment times. The results do not demonstrate a significant treatment effect, suggesting that L2 learners' integrative perceptions were stable over the course of the semester. The dynamics in the perception changes differed widely across the perception groups. This result provides insights into understanding students' reading-writing practices and thus into instructional practices applicable to the classrooms. The present study argues for 12 learners' perceptions on integrating reading and writing as a key construct to understand their literacy practices involved in the composing process.

  • The study investigated the linguistic characteristics of middle school students' writing on the themes of earth science through analysis of its genre and register. Data for analysis included $7^{th}$ grade and $9^{th}$ grade students' writings about 'global warming' and 'classification of rocks'. The results of this study include: First, many students were not accustomed to writing in genre, especially exposition genre. Second, in terms of ideational meaning, the material verbs representing action or doing were more dominant than relational verbs that are related to the attribute or definition of things, and additional logical relations were predominant. Third, regarding interpersonal meaning, agents, emotions, subjective opinions appeared in the writings and students did not express their ideas conclusively and revealed feelings of doubt and uncertainty about their knowledge. Fourth, as for textual meaning, most students listed fragments of information using additional conjunctions in simple structures and were not accustomed to writing texts with organizing structures, logical patterns, cohesion, and coherence. From these results, we argued that the scientific writings should be emphasized in science learning that aims to foster scientific literacy. In addition, we discussed the necessity of improving science teachers' perceptions on scientific writing as well as setting up a specific plan in the national curriculum.

Drawing and Writing as Methods to Assist Students in Connecting and Integrating External Representations in Learning the Particulate Nature of Matter with Multiple Representations (물질의 입자적 성질에 대한 다중 표상 학습에서 외적 표상들 간의 연계와 통합을 촉진시키는 방안으로서의 그리기와 쓰기)

  • This study investigated the effects of drawing and writing as methods to assist students in connecting and integrating multiple external representations provided in learning the particulate nature of matter. Seventh graders (N=224) at a coed middle school were assigned to a control group, a drawing group, and a writing group. The students were taught about "Boyle's Law" and "Charles's Law" for two class periods. Students observed macroscopic phenomena through experiments. After this observation, students in the control group learned the topic with both external visual and verbal representations simultaneously. Students in the drawing group drew their mental model from the external verbal representation provided, and then compared their drawing with external visual representation. Students in the writing group wrote their mental model from the external visual representation provided, and then compared their writing to the external verbal representation. The two-way ANCOVA results revealed that the scores of a conception test for the writing group were significantly higher than those for the control group. While the drawing group performed better than the control group, the difference is relatively smaller. There were no significant interactions between the instruction and spatial visualization ability in the scores of the conception test. Most students perceived the writing or drawing activities helpful in understanding the concepts, and a few students responded that the writing or drawing activity was interesting. Educational implications were discussed.

  • This study aims to explore group inquiry using science writing heuristic in elementary school science. We observed and examined what elementary students experienced in their science classes and moreover how they used their data to support their claims in the view point of scientific epistemology. The research question of this study is 'what is the result of coherence measurement for figuring out the relationship between argument and ground in group inquiry activity?'. To solve the study question, one fifth-grade class at an elementary school was selected. Four lessons in group inquiry using a worksheet of science writing heuristic were videotaped and transcribed. It was found that the hours of group inquiry when students can discuss meaningfully occupied approximately 37 to 45%. When measuring coherence in each lesson by developing a scale from one to five to estimate the coherence of the work sheet designed, the total average was 3.424. It implicated that students had their claims supported by some of their evidences. Although the figure was not enough to assist that they found strong bonds between their claims and data, they started to move forward to epistemological approach in their science lab works.

  • Zinc tin oxide (ZTO) sol-gel solution was synthesized for ink-jet printable semiconducting ink. Bottom-contact type TFT was produced by printing the ZTO layer between the source and drain electrodes. The transistor involving the ink-jet printed ZTO had the $mobility\;{\sim}\;0.01\;cm^2V^{-1}s^{-1}$. We demonstrated the direct-writing of semiconducting oxide for solution processed TFT fabrication.
