This study aims to examine the effects of CF about learners' English writing through FL on English improvement and the factors that influence class satisfaction. For achieving this purpose, response to CF and feelings about CF were selected as predictive variables. It is intended to investigate how these variables predict learners' satisfaction. A total of 94 university students were placed into two groups: 48 experimental group, who received CF on their writing through FL, and 46 control group given traditional instruction. All the participants took pre/post tests including writing tasks, and the experimental group completed a questionnaire after the instructional treatment. The findings indicated that FL affected English improvement and both response to CF and feelings about CF predicted class satisfaction. Based on the findings, this study sheds light on the implications of how to manage the FL class efficiently.

The purpose of this study was to examine the influence of reading framework on writing for reflection when applied to inquiry-based Science Writing Heuristic approach. This study was conducted with 67 3rd grade middle school students. Thirty-two out of 67 students were assigned to R-SWH (Reading framework-Science Writing Heuristic) group while the other 35 students were assigned to SWH (Science Writing Heuristic) group. The R-SWH group has consistently used reading framework which the SWH group has not used when the inquiry-based science writing heuristic approach were carried out. The result of this study indicated that the R-SWH group showed a higher proportion of students who made writing for reflection by learning from reading materials than the SWH group. The R-SWH group used reading materials in order to understand the idea comprehensively and concept related to the topic the most, while the SWH group also used them for the same purpose as the R-SWH group but the ratio was less than the R-SWH group. In addition, as the learning activity has progressed, the R-SWH group showed that the proportion of students who transferred the science concept from reading materials into writing for reflection and the number of transferred concepts were higher than those of the SWH group. Therefore, the reading framework applied to inquiry-based science writing heuristic approach can facilitate a meaningful activity on reading and writing as a scaffolding to develop conceptual understanding.

The purpose of this research was to investigate the relationship between the change of beginning teachers' beliefs about a lesson and that of teaching practice and argument-based inquiry using science writing. Participants were three science teachers (A, B, and C) from different middle schools. Classroom observation and interview data were collected and transcribed for analysis. A Summary Writing test was also administered to examine whether there was an improvement in students' learning. The results indicated that the interaction between the teachers and their students developed, which is concluded as an improvement in the teaching practice. Teacher A and B also reported that teacher-student interaction had improved. Teacher A and C came to understand that argument-based inquiry using science writing classes constituted learner-centered instruction. The result from the Summary Writing Test showed the impact of the changes in teaching practice and in teachers' awareness of students' learning as well as produced meaningfully higher scores than compared groups on the rhetorical structure of all the specific areas in teacher A's school and on the scientific concept at B and C's schools.

The purpose of this study was to investigate the effect of science writing for different audiences on preservice chemistry teachers' chemistry concept understanding and modeling ability in general chemistry experiment activities using Argument-based Modeling (AbM) strategy. And we also examined preservice chemistry teachers' perceptions of modeling in different audience groups. The participants of the study were 18 university students in the first grade of preservice chemistry teachers taking a general chemistry experiment course. They completed eleven topics of general chemistry experiment using argument-based modeling strategy. The understanding of chemistry concept was compared with the effect size of pre- and post-chemistry concept test scores. To find out modeling ability, we analyzed level of model by each preservice chemistry teacher. Analytical framework for the modeling ability was composed of three elements, explanation, representation, and communication. The questionnaire was conducted to check up on preservice chemistry teacher's recognition of modeling. The result of analyzing the effect of modeling for different audience on the understanding of chemistry concept and modeling ability, the preservice chemistry teachers' were found to be more effective when the level of audience was low. There was no difference in the recognition of modeling between the groups for audience. However, we could confirm that the responses of preservice chemistry teachers are changed in concrete when they have an experience in succession on modeling.

The purpose of this study was to examine the effects of Argument-based Inquiry activities on the claims and evidence in elementary students' science writing. Participants were thirty three fifth grade elementary school students and argument-based inquiry activities on five topics were implemented. We analyzed the Summary Writing samples written by students to investigate the effect of the Argument-based inquiry activities on elementary students' claims and evidence in their science writing, and also analyzed the writing samples of the experimental group to which the Argument-based inquiry activities were implemented, to examine the change of claims and evidence. The results of this study showed that the mean of experimental group was significantly higher than that of the comparison group. As a result of analyzing claims and evidence in Summary Writing of experimental group, the level of claim and evidence has tended to increase gradually as the number of classes progresses.

This study aimed to explore the role of models and reformulations as feedback to English writing in L2 learners' noticing and their writing. 92 participants were placed into three groups; a models group (MG), a reformulations group (RG), a control group (CG), involved in a three-stage writing task. In stage 1, they were asked to perform a 1st draft of writing, while taking notes on the problems they experienced. In stage 2, the MG was asked to compare their writing with a model text and the RG with a reformulated version of it. They were instructed to write down whatever they noticed in their comparison. The CG was asked to just read their writing. In stage 3, all the participants attempted subsequent revisions. The results indicated that all the participants noticed problematic linguistic features the most in a lexical category, and models and reformulations led to higher rate of noticing the problematic linguistic features reported in stage 1 and contributed to subsequent revisions. It was also revealed that the MG and RG significantly improved with their writings of MG and RG on the post-writing test. The findings imply that models and reformulations result in better performance in L2 writing and should be promoted in an English writing class.

Peer assessment in educational setting, refers to activities in which students provide grades or comments on other students' accomplishments such as writing, presentation, or performances. In case of writing, peer assessment can allow instructors to give out more writing assignments, which were often avoided because of the burden of grading. Moreover, grading other students' writing can enhance learning by having students participate in the assessment process. This review will introduce major peer assessment systems and results from empirical studies on peer assessment, examine obstacles to its more wide-spread use, and discuss topics for further research. We hope this paper will facilitate further studies and use of peer assessment in actual educational settings, and eventually lead to many changes in assessment and teaching in Korea.

The purpose of this study is to investigate the impact of argument-based modeling strategy using scientific writing on student's modeling ability. For this study, 66 students (three classes) from the 7th grade were selected and of these, 43 students (two classes) were assigned to two experimental groups while the other 23 students (one class) were assigned to comparative group. In the experimental groups, one group (22 students) was Argument-based multimodal Representation and Modeling (AbRM), and the other group (21 students) was Argument-based Modeling (AbM). Modeling ability consisted of identifying the problem, structuring of scientific concepts, adequacy of claim and evidence and index of multimodal representation. As for the modeling ability, AbRM group scored significantly higher than the other groups, AbM group was significantly higher than comparative group. The four sub-elements of modeling ability in the AbRM group was significantly higher than the other groups statistically and AbM group scored significantly higher than comparative group. From these results, the argument-based modeling strategy using scientific writing was effective on students' modeling ability. Students organized or expressed the model and evaluated or modified it through the process of argument-based modeling using scientific writing and the exchange of opinions with others by scientific language as argument and writing.

This study focused on the use of student assessment activities to investigate the impact on reflective thinking in Argument-based Inquiry. The participants of the study were 166 10th grade students (six classes). Over one semester, students participated in five ABI programs that we developed. The experimental group (84 students) was taught Argument-Based Inquiry with students' self and peer assessment activities. The comparative group (82 students) was taught without the activities. We analyzed students' reflective writing to investigate how the student assessment activities influenced the students' reflective thinking. We also used the interviews and surveys to examine the validity of student assessment activities. According to analysis of the reflective writing, the experimental group had a significantly higher mean score than the comparative group in the 3rd and 5th writing. The ratio of students who showed a metacognitive level of reflection with regard to analysis of inquiry process, understanding of learning, and change of thinking increased in both groups, but the experimental group's ratio was higher than the comparative group's. The result of analysis of the reflective practice showed that the ratio of the experimental group's students who reached the metacognitive level of reflection in their writing increased, while the comparative group's decreased. Therefore, we conclude that student assessment activities can create a learning environment that facilitates student participation, increases the students' engagement in the learning process, and can be used as a tool to scaffold learning.

This study explores the effects of different Focus-on-Form Instruction (FFI) on improving learners' grammatical knowledge development and observes how the learners apply the knowledge to their output. A total of 112 college students were placed into three groups: 35 input-enhanced group students, who received visually enhanced input reading materials, 41 output-enhanced group students, performing dictogloss tasks, and 46 control group students given traditional grammar instruction. All the participant students took pre/post grammatical tests and completed pre/post writing tasks, which aimed to look into how the target grammatical structures were used in writing. The research findings indicated that both input-enhanced and output-enhanced FFI were effective on learners' language form learning and made contribution to their writing. Based on the findings, this study suggests that the elaborate design of combination of both FFI can maximize learners' language form learning.
