Predicting pre-service teachers’ intention of implementing peer assessment for low-achieving students

임수연,조영환 서울대학교 교육연구소 2016 Asia Pacific Education Review Vol.17 No.1

Despite the benefits of peer assessment, many teachers are not willing to implement it, particularly for low-achieving students. This study used the theory of planned behaviour to predict pre-service teachers’ intention to use peer assessment for low-achieving students. A total of 229 pre-service teachers in Singapore participated in the survey which consists of eight factors about peer assessment in writing: belief of knowledge source, belief of ability, belief of constructivist assessment, attitude, subjective norm, perceived behaviour control, behavioural intention, and intention for low-achieving students. Structural equation modelling was used to test hypothesized relationships of the eight factors. This study found that pre-service teachers’ beliefs about knowledge source and constructivist assessment significantly influenced their attitude towards peer assessment of writing. In addition, the attitude and perceived behaviour control were significant factors in shaping the intention of peer assessment. Lastly, pre-service teachers’ intention of implementing peer assessment for low-achieving students was influenced by both the intention of peer assessment and the belief of ability.

임수연,이향숙,추상호 한국ITS학회 2016 한국ITS학회논문지 Vol.15 No.2

본 연구의 목적은 서울시의 환승통행 특성을 분석하고 토지이용이 환승통행에 미치는 영향을 규명하는 것이다. 이를 위해 서울시의 2013년 4월 평일 하루치 교통카드자료를 이용하여 환승통행의 일반적인 특성을 분석하고, 토지이용과 사회경제지표 등을 독립변수로 고려한 환승통행량의 다중선형 회귀모형을 구축하였다. 환승통행특성의 경우, 환승통행 이 전체 통행의 26.7%를 차지하였으며, 이 중 1회 환승한 경우가 86.4%로 대부분이었다. 또한 버스-지하철간 환승이 64.7%로 큰 비중을 차지하였며, 주로 지하철 역 및 업무시설이 다수 위치하는 곳에서 환승통행이 많이 발생하였다. 회 귀모형 구축 결과, 업무시설면적비율 및 백화점시설의 면적비가 높거나 복합토지이용도가 높은 지역일수록 환승통행량 이 많아지는 것으로 분석되었다. 본 연구의 결과는 향후 복합환승센터와 같이 도시 내 환승통행을 고려하는 교통시설의 입지 선정을 위한 기초자료로 활용될 수 있을 것이다. This paper is to analyze characteristics of transfer trips and to identify impacts of land use on them. Using the smart transport card data of Seoul on a weekday in April 2013, we explored general characteristics of the transfer trips such as spatial and temporal distributions, transfer types, and geographical patterns of transfer trips. Then, the multiple regression model for the transfer trips was developed, considering land use as well as socio-economic variables as explanatory ones. For the characteristics of the transfer trips, their ratio to the total trips accounts for 26.7%. Nearly 87% of the trips are one-time transferred, and 64.7% are bus-subway transfer trips. In addition, the transfer trips are more likely to appear nearby subway stations and business facilities. The regression model indicates that land use variables such as the floor areas of business facilities and department stores and mixed land use index significantly positively affect the transfer trips. Our results can be used as basic data for choosing feasible locations of multi-modal transfer centers in urban areas.

초등학교 영어교사의 전문성 평가도구 개발: 정의적 요인을 중심으로

임수연 한국영어교육학회 2014 ENGLISH TEACHING(영어교육) Vol.69 No.2

This study was designed to develop a scale to measure primary school Englishteachers’ professionalism based on affective factors. The Swailes' (2003) scale wasused to best reflect the local context where teachers in primary schools teach English toyoung learners. Three surveys were sent to a total of 1,008 primary school Englishteachers. Three different focus groups were used to refine the survey items in themodification process from the first to the third survey. The data were analyzed usingexploratory factor and confirmatory factor analysis. These results showed the validityof fifteen items for investigating primary English teachers’ professionalism: four itemsrelated to 'professional commitment', three related to 'professional autonomy', threeitems related to professional belief in public service, three items to profession asreferent, and two items to professional regulation. It is hoped that the scale itemsdeveloped in this study can be used to identify the standard of professionalism ofprimary English teachers and provide policy makers or school decision makers withdata that can be used to enhance professionalism within the community of primaryEnglish teachers.

Implementation of Self-expression Tool with Interactive Hangeul

임수연 한국인터넷방송통신학회 2018 International Journal of Internet, Broadcasting an Vol.10 No.4

Modern people communicate in a digital space without being limited by physical space and time. On the internet, people's desire for self-expression is getting bigger, and the most common self-expression tool is characters. Characters are visual materials to express human thoughts and desires. This study is a method to positively express the viewer's self in an interactive Hangeul system. The proposed system produces new formative shapes and meanings of Hangeul through the process of deconstructing and reconstructing the characters. Immediate character transformations that are synchronized with the motion of the viewer act as a tool of self-expression by inducing the viewer's active interaction repeatedly. Therefore, the proposed interactive Hangeul is more than enough to be used as a new graphic tool beyond the text to be read, and it is highly likely to develop into cultural contents using it.

Adjuvant role of macrophages in stem cell-induced cardiac repair in rats

Bone marrow-derived mesenchymal stem cells (BMMSCs) are used extensively for cardiac repair and interact with immune cells in the damaged heart. Macrophages are known to be modulated by stem cells, and we hypothesized that priming macrophages with BMMSCs would enhance their therapeutic efficacy. Rat bone marrow-derived macrophages (BMDMs) were stimulated by lipopolysaccharide (LPS) with or without coculture with rat BMCs. In the LPS-stimulated BMDMs, induction of the inflammatory marker iNOS was attenuated, and the anti-inflammatory marker Arg1 was markedly upregulated by coculture with BMMSCs. Myocardial infarction (MI) was induced in rats. One group was injected with BMMSCs, and a second group was injected with MIX (a mixture of BMMSCs and BMDMs after coculture). The reduction in cardiac fibrosis was greater in the MIX group than in the BMC group. Cardiac function was improved in the BMMSC group and was substantially improved in the MIX group. Angiogenesis was better in the MIX group, and anti-inflammatory macrophages were more abundant in the MIX group than in the BMMSC group. In the BMMSCs, interferon regulatory factor 5 (IRF5) was exclusively induced by coculture with macrophages. IRF5 knockdown in BMMSCs failed to suppress inflammatory marker induction in the macrophages. In this study, we demonstrated the successful application of BMDMs primed with BMMSCs as an adjuvant to cell therapy for cardiac repair.

Implementation of Interactive Self-portrait using Real-time News Stream

임수연 한국인터넷방송통신학회 2018 Journal of Advanced Smart Convergence Vol.7 No.4

This study is about the interactive self-portrait which provides the experience of self-consciousness reflection of the viewer to modern people who are easily alienated in rapid social change. We proposed interactive self-portrait is implemented by an interactive mirror that reproduces the appearance of the viewer acquired using a webcam. The interactive mirror, which can directly project its own image, is drawn by searching news articles in real time and using the extracted characters as pixel information in real time. The viewer has the opportunity to experience a new style of active self-expression while watching his/herself composed of news characters that are issues of modern society. The virtual self-portrait designed with news characters can attract viewers' attention by visually expressing the interests of modern people and can act as an incentive to generate positive interaction.

Information Status and Prosodic Prominence as Perceived by Korean Learners of English

임수연 서울대학교 언어교육원 2019 語學硏究 Vol.55 No.2

This study investigates the relationship between information status and prosodic prominence perceived by Korean learners of the English language, compared to English native speakers, in a complete public speech. Both groups of speakers were asked to mark words that they perceived as being prominent, while listening to a speech in real time. The information status of a word was annotated as a function of referential and lexical information, as well as focus. The results show that Korean native speakers perceive prosodic prominence in a similar manner to that of English native speakers. Both groups are more likely to perceive prominence for new or focused words than for given or non-focused words. The two groups, however, differ in that Korean native speakers tend to more frequently perceive prominence for words carrying lexical information than English native speakers. This bias seems to be influenced by parts-of-speech, in alignment with the findings of previous studies.
