자동 쓰기 평가 연구는 쓰기 답안지를 채점하는데 드는 시간과 비용을 절감할 수 있어, 교육 분야에서 큰 관심을 가지고 있다. 본 연구의 목적은 쓰기 답안지의 문서 구조를 효과적으로 학습하여 평가하고, 문장단위의 피드백을 제공하는데 있다. 그 방법으로는 문장 레벨에서 한국어 Sentence-BERT 모델을 활용하여 각 문장을 임베딩하고, LSTM 어텐션 모델을 활용하여 문서 레벨에서 임베딩 문장을 모델링한다. '한국어 쓰기 텍스트-점수 구간 데이터'를 활용하여 해당 모델의 성능 평가를 진행하였으며, 다양한 KoBERT 기반 모델과 비교 평가를 통해 제안하는 모델의 방법론이 효과적임을 입증하였다.

This paper proposes an improved write-piggybacking technique called hybrid write-piggybacking, and evaluates its performance. The performance of the proposed hybrid write-piggybacking technique is done through a trace-driven simulation using a model of a real disk system. The results of simulation show that the proposed hybrid write-piggybacking has better performance compared to the original write-piggybacking technique.

The purpose of this study is to identify the influence of users' satisfaction with the Automatic Writing Evaluation(AWE) on learners' sense of learning achievement through self efficacy in English writing class. AWE is a tool that automatically provides feedback on writing outputs by AI technology. College students were asked to write essays for each topic and use AWE to get feedback on their drafts, and finally revise them referring to the feedback. A questionnaire survey was conducted for the data collection. The data was analyzed using SPSS, and smart PLS-SEM along with bootstrapping techniques, The results of the study reveal the followings: 1) the convenience and usefulness of AWE had a positive effect on the willingness to reuse it; 2) the satisfaction with AWE had a positive effect on self-efficacy; 3) self-efficacy had a positive effect on learning achievement in terms of emotional and linguistic aspects. With the development of the 4th industry and A.I. technology, it is recommended to introduce new materials or programs such as AWE in English education.

글쓰기과외가 성행하면서 글쓰기에 대한 관심이 출판계에도 영향을 미치고 있다. 어린이용 글쓰기지침서가 벌써 30여 종이나 출판된 것을 비롯해서 고교생이나 성인용 글쓰기지침서도 심심찮게 찾아볼 수 있는 실정이다. 글쓰기에 대한 관심은 대학입시 정책의 변화에 기인하는 것이라는 부정적 측면 이외에도 창조적인 사고를 할 수 있다는 점에서 긍정적으로 평가하는 이들도 많다. 하지만 많은 글쓰기지침서 중에서 정작 필요한 책을 고르기는 쉽지 않다. 책 선별의 첫째 조건은 "어느것이 올바른 글쓰기인가"라는 물음에서 비롯되어야 한다고 관계자들은 말한다. 이와 함께 "글이란 것은 만들어지는 것이 아니라 올바른 삶을 살아가면서 느끼는 감동을 자연스럽게 표현하는 것"이라는 관점에서 글쓰기를 본다면, 글쓰기지침서가 자칫 고정관념을 만들어낼 수도 있다는 지적도 있다.

The purpose of this study is to examine the effects of small group discussion on elementary students' science writing. In this study, four 6th grade students were chosen from an elementary school in Seoul. Students were involved in eight science writing classes and the contents of a small group discussion and interactions were recorded and observed. Students' science works were collected and analysed based on three domains: scientific thinking, logic and originality. The result of this study showed that the contents of a small group discussion greatly affected the scientific thinking domain. A low-achieving student received lots of help from a high-achieving student. It was easy to improve in the logic domain through the science writing classes. Average students got good grades in an originality domain when the subject was related to their real life. A small group discussion would have an effect on science writing ability positively if the students acquired proper guidance on the procedure and manner of discussion. The science writing lesson would be more effective if the learning group was organized homogeneously in the aspects of intelligence achievement and interpersonal relationships.

Objective : The purpose of this study is to investigate the impact of task-oriented approach based on upper limb coordinated movement on the ability of the Korean handwriting in children with developmental coordination disorder(DCD). Methods/Design : This randomized controlled trial designed as a pre-/post- test will compare the effectiveness of task-oriented approach and process-oriented approach on handwriting performance for children with DCD aged 5 to 10. These interventions consist of 10 training sessions and 4 assessment sessions over 7weeks. Children will be measured regard to handwriting legibility, speed and pre-handwriting skills including upper limb movement skills, visual perception and visual motor coordination. Conclusion : This is the first attempt to investigate effects of a task-oriented approach in children with DCD. The significance of this study is to provide the clinical evidences to apply the task-oriented approach improves the children's handwriting performance. Furthermore it will also present a more effective intervention for handwriting by figuring out each approach's impact on the improvement of pre-handwriting skills.

Although evaluation of writing disabilities identification and timely intervention are required, clinicians adopt a manual scoring method and there is a possibility of error due to subjective evaluation. In this study, the size ratio and position of letters are digitized and quantified through image processing of offline handwritten characters. We tried to evaluate objectively and accurately the performance of writing through comparison with existing methods. From November 12th to 16th, 2018, 20 adults without neurological injury were selected. They used a pencil to follow the 10 words, 2 sentence stimuli after keeping the usual habit, and we collected the writing test data. The results showed that the height of the word was 1.2 times larger than the width and it tilted to the lower left. The spacing interval was 9mm on average. In the Paired T test, a high correlation was showed between our system and existing methods in the word and sentence 2. This demonstrated the possibility as a testing tool. This study evaluated objectively and precisely writing performance of offline handwritten characters through image processing and provided preliminary data for performance standards. In the future, it can be suggested as a basic data on writing diagnosis of various ages.

The atomic write technique is a good solution to solve the problem of the double write buffer. The atomic write technique needs modified I/O subsystems (i.e., file system and I/O schedulers) and a special SSD that guarantees the atomicity of the write request. In this paper, we propose the writing unit aligned block allocation technique (for EXT4 file system) and the merge prevention of requests technique for the CFQ scheduler. We also propose an atomic write-supporting SSD which stores the atomicity information in the spare area of the flash memory page. We evaluate the performance of the proposed atomic write scheme in MariaDB using the tpcc-mysql and SysBench benchmarks. The experimental results show that the proposed atomic write technique shows a performance improvement of 1.4~1.5 times compared to the double write buffer technique.

This study aims to analyze through the integrated textbooks whether writing tasks are designed to be successful in cultivating students' writing abilities in the general-purpose Korean language education. First, we established the concept and the components of the writing task based on the definitions mentioned in previous research. The analysis of the types of writing tasks revealed "free writing" and "imitation and writing" to be the most frequent types of writing tasks in both textbooks. The textbooks have only twenty-one subjects in common. And most instructions provide only themes and genres, excluding the purpose, form, quantity, and time necessary for the article or for comprehending the instructions. In these tasks, the reading passages are most often explanatory text. The scoring criteria and time were not provided for the evaluation criteria and other factors. Therefore it became necessary to express the components of the writing task as explicitly and concretely as possible to improve learners' performances.

The purpose of this study was to examine the effect of essay writing-centered mathematics instruction on problem solving and mathematical deposition in the elementary school. For the present study, two 6th grade classes with equivalent achievement in terms of problem solving and mathematical disposition based on the pretest. A total of 15 mathematics lessons focused on writing activities were administered to the experiment group for two months, while the textbook-based traditional lessons were given to the comparison group. Both quantitative and qualitative methods were adopted to analyze the data. The results of the present study showed that essay writing-centered mathematics teaching is statistically superior that the textbook-based mathematics teaching with respect to students' problem solving and mathematical disposition. In addition, it was evidenced that essay writing-centered mathematics instruction makes an influence on students' perceptions toward essay-based assessment in a positive way.
