Using Math Journals to Enhance Second Graders’ Communication of Mathematical Thinking     

Kathleen Kostos  Eui-kyung Shin 《Early Childhood Education Journal》2010,38(3):223-231

As an action research project, using mixed methodology, this study investigated how the use of math journals affected second grade students’ communication of mathematical thinking. For this study, math journal instruction was provided. The data gathering included pre- and post- math assessment, students’ math journals, interviews with the students, and teacher’s reflective journal. Findings of the study indicated that the use of math journals positively influenced the students’ communication of mathematical thinking and the use of math vocabulary. Additionally, math journals served as a communication tool between the students and teacher and an assessment tool for the teacher. The implications of this study regarding students’ writing ability and time constraints issues were also discussed.  相似文献   

Multi-postpath-based lookahead multiconstraint QoS routing     

Dong-won Shin  Edwin K.P. Chong  Howard Jay Siegel 《Journal of The Franklin Institute》2012,349(3):1106-1124

Multiconstraint QoS (quality of service) routing is an essential mechanism for QoS-guaranteed services. Unfortunately, the multiconstraint QoS routing problem is NP-complete. In this paper, we propose a heuristic multiconstraint QoS routing scheme, MPLMR (multi-postpath-based lookahead multiconstraint routing). MPLMR is a routing scheme using an extended shortest-path algorithm. As in previous schemes such as TAMCRA and H_MCOP, MPLMR stores a limited number of subpaths between the source node and each intermediate node, and extends these subpaths toward the destination node. However, MPLMR uses an improved “lookahead” method to estimate the path length of the full path to which each subpath is extended. MPLMR then selects and stores the subpaths that have higher likelihood than other subpaths to be extended to feasible paths. We show via simulation that MPLMR has a smaller probability of missing a feasible path than competing schemes in the literature.  相似文献   

The effects of message source and fear appeal on young adults’ response to Sexually Transmitted Disease (STD) messages in Singapore     

Hyo Jung Kim  Wonsun Shin 《亚洲交流杂志》2018,28(2):185-204

This study examines the psychological processes that determine how fear appeal and sponsor type impact young adults’ responses to public campaigns against Sexually Transmitted Diseases (STDs) in Singapore. The results showed that fear appeal in the STD messages increased the level of anger arousal, while the STD messages sponsored by a commercial company versus a government agency increased the level of negative cognitions among participants. The interaction between fear appeal and sponsor type was found in both affective and cognitive responses of psychological reactance against the STD messages.  相似文献   

Issue competition and presidential debates in multiparty systems: evidence from the 2002, 2007, and 2012 Korean presidential elections     

Jungsub Shin 《亚洲交流杂志》2017,27(3):233-249

Which issues do political parties emphasize in campaigns? Selecting the issues to emphasize in campaigns is treated with the same importance as policy positioning. Nevertheless, little attention has been paid to understanding parties’ strategies of issue competition in presidential elections under multiparty systems. By analyzing statements of presidential candidates in the 2002, 2007, and 2012 Korean presidential debates, we find that presidential candidates use their issue emphasis strategies differently in presidential elections according to party size and ideological relationships with other parties. Specifically, a small party’s candidates have been more likely than mainstream parties’ candidates to pursue their issue ownership advantage. In addition, a mainstream party’s candidates have emphasized the issues of a small party more than those of his own party when the two parties have had a similar ideological foundation, whereas, when there were no such ideological similarities, a mainstream party’s candidate has only focused on issues of the mainstream party. Our results imply that the political communication used by political parties and candidates is conditioned not only by political contexts such as electoral systems or party systems but also by the size and ideology of parties.  相似文献   

Environmental Education Course Development for Preservice Secondary School Science Teachers in the Republic of Korea     

Donghee S. Shin 《The Journal of environmental education》2013,44(4):11-18

Abstract

In Summer 1996, an opinionnaire survey was used to evaluate the opinions of Korean professors, in earth science education and geology departments, about the science concepts related to environmental issues that might be important for secondary preservice earth science teachers in the Republic of Korea. The opinionnaire contained 63 items within the 14 major topics being considered. It used a 4-choice, Likert-type scale and was completed by 47 professors (response rate = 51%). There was a good coincidence in opinions on major topics to be included. Respondents favored an environmental earth science course that emphasized the “human impact on the environment” rather than “natural environmental hazards.” Also, they favored study of natural hazards that commonly occur in Korea within a context of worldwide natural hazards.  相似文献   

End-of-Life Decision Making in Older Korean Adults: Concerns,Preferences, and Expectations     

Eunjeong Ko  Holly Nelson-Becker  Youngjoon Park  Minjung Shin 《Educational gerontology》2013,39(2):71-81

This study explored Korean older adults’ concerns and preferences regarding end-of-life care and the expected role of physicians in the decision making process. The purpose was to assist health care professionals, in particular, physicians, to better understand how to interact with Korean older adults. A qualitative method using in-person interviews was conducted with Korean older adults (N = 54). The seven main themes generated in this study included the following: (a) life-sustaining treatments and hope for quality of life; (b) physician expert status; (c) truth telling and ethics; (d) preferred way to disclose bad news; (e) physician's role to treat, (f) potential misuse of life-sustaining treatments; and (g) priority of patients’ preferences. Overall, study participants generally anticipated a larger role for physicians in their own end-of-life decision making, though some expressed concerns about the outcome of giving such power to physicians, especially in agreeing to life-sustaining treatments. Although culture provides one important clue about expectations, it is always crucial for health care providers to ask about individual preferences and to develop an open communication style to decrease distress. Our findings highlight the importance of understanding concerns and preferences regarding end-of-life care among Korean older adults and the importance of assisting them in planning end-of-life care within a cultural framework.  相似文献   

Simulation of gait asymmetry and energy transfer efficiency between unilateral and bilateral amputees     

Navid Aslani  Siamak Noroozi  Khoo Shin Yee  Alex Ong Zhi Chao  Christine Maggs 《Sports Engineering》2016,19(3):163-170

Efficient walking or running requires symmetrical gait. Gait symmetry is one of the key factors in efficient human dynamics, kinematics and kinetics. The desire of individuals with a lower-limb amputation to participate in sports has resulted in the development of energy-storing-and-returning (ESR) feet. This paper analyses a case study to show the effect of symmetry and asymmetry as well as energy transfer efficiency during periodic jumping between simulated bilateral and unilateral runners. A custom gait analysis system is developed as part of this project to track the motion of the body of a physically active subject during a set of predefined motions. Stance and aerial times are accurately measured using a high speed camera. Gait frequency, the level of symmetry and the non-uniform displacement between left and right foot and their effects on the position of the Centre of Mass (CM) were used as criteria to calculate both peak energies and transformation efficiency. Gait asymmetry and discrepancy of energy transfer efficiency between the intact foot and the ESR are observed. It is concluded that unilateral runners require excessive effort to compensate for lack of symmetry as well as asymmetry in energy transfer, causing fatigue which could be a reason why bilateral amputee runners using ESR feet have a superior advantage over unilateral amputees.  相似文献   

Changes in science classrooms after experiencing an international professional staff development program     

Myeong-Kyeong Shin  Robert E. Yager  Phil Seok Oh  Mee-Kyeoung Lee 《International Journal of Science and Mathematics Education》2005,1(4):505-522

This professional development program was designed to prepare science teachers to be more student-centered and to implement newer goals for science instruction. These goals are to improve science teaching in ways that promote broader and longer-lasting learning. Secondary school science teachers in Korea are expected to follow a rigid national curriculum with large classes - often with more than 50 students. This study focuses on feedback and follow-up interaction with teacher participants who were enrolled in a month-long workshop in the U.S. before returning to Korea to implement the new ideas. Assistance was offered to help teachers develop teaching modules which were more constructivist while also assisting with assessment efforts that provided further evidence of use of the new teaching practices and their effect on student learning. Student mastery of concepts and improvement in student creativity were two aspects of the summer workshop experiences and these were evaluated to illustrate workshop effects on teacher participants in their actual classrooms.

Rethinking the hermit kingdom: US social studies teachers’ cross-cultural professional development in South Korea     

Yoonjung Choi  Eui-Kyung Shin 《Asia-Pacific Journal of Teacher Education》2016,44(2):188-202

This study explores the experiences of 34 US social studies teachers who participated in a cross-cultural professional development in South Korea, and the impact of the programme on the participant teachers’ perceptions and practices of global education. Drawing upon a postcolonial lens, this mixed-method study takes a critical look at (a) how social studies teachers who mostly had limited previous knowledge of and experiences with the host country experienced cross-cultural learning and (b) how the teachers’ experiences were applied to their perceptions on global education and actual curricular and pedagogical changes in the classroom. The findings of this study provide solid empirical evidence on the possibilities and limitations of such international professional development, particularly in non-Western contexts, and discuss the implications on global teacher education.  相似文献   

A review of human competence in educational research: Levels of K- 12, College, Adult, and Business Education     

Minseong Kim  Soonkyoung Youn  Minjeong Park  Kyoung-Oh Song  Tacksoo Shin  Jeongmin Chi  Jongho Shin  Deokhee Seo  Sungdoo Hong 《Asia Pacific Education Review》2007,8(3):500-520

The purpose of this study is to review the main perspectives or issues dealt with in the research on considered to be key competences, in order to develop a fuller understanding of how human competence functions. As a result of this review, two themes considered as having important implications for the actual practices can be identified: that there exists an holistic nature with different aspects of a given competence and that influences of a contextual and cultural nature are factors which affect the operation of human competence. By incorporating four characteristics and three domains of competence with the review conducted in this study, we began to appreciate what the research on human characteristics related to key competences has achieved and what is needed for future research.  相似文献
