Becoming Co-Authors: Toward Sharing Authority in Religious Education     

Hyun-Sook Kim 《Religious education (Chicago, Ill.)》2013,108(5):479-491

This article offers an alternative model, the model of shared authority, to the traditional, authoritarian model for authority and obedience for Religious Education. This model moves away from the authoritarian model of a teacher as the authority and the students as obedient listeners in the direction of a shared authority model in which teachers and students participate in learning as partners, in other words, “to become co-authors.”  相似文献   

New Vision and Challenges in Inquiry-Based Curriculum Change in Singapore     

Mijung Kim  Frederick Toralballa Talaue 《International Journal of Science Education》2013,35(2):289-311

A new primary science syllabus with strong inquiry focus has been implemented in Singapore since 2008. In this study, we attempted to understand how teachers experience the emphasis of inquiry-based curriculum under the current educational conditions that is routined and highly teacher fronted. We invited 50 pre-service and 41 in-service teachers to participate in survey questionnaires and narratives, reflective writings, and group discussions related to science inquiry which formed our data corpus. Data analysis in the form of thematic coding was carried out using NVivo8, with over 80% inter-rater coding agreement level. Three key aspects of teachers’ perceptions of science inquiry were revealed: (1) teachers’ responsibilities as facilitators, (2) privileging content knowledge rather than process skills, and (3) pressure of assessment systems in current educational contexts. These understandings bring out conflicts of inquiry teaching between teacher- and student-centredness, content and process, and curriculum and assessment. Based on these teachers’ perceptions and dilemmas of inquiry science teaching, the visions and challenges of inquiry science curriculum change against assessment requirements are discussed.  相似文献   

Kicking modality during erratic-dynamic and static condition effects the muscular co-activation of attacker

The purpose of the study was to investigate the effect of different kicking modality, i.e., erratic-dynamic target (EDT) versus static target (ST) on the performance of the roundhouse kick in two groups of taekwondo athletes of different skill level. Three-dimensional analysis and surface electromyography (SEMG) analysis were performed on 12 (Group A: six sub-elite, Group B: six elite) athletes to investigate muscle co-activation pattern under two conditions, i.e., EDT versus ST. In the results, the muscle recruitment ratio of the agonistic muscles was higher for Group A, whereas Group B had higher recruitment ratio for antagonist muscles. Overall, the co-activation index (CI) of hip joints appeared higher in the extensors for Group A, whereas higher CI was observed in flexor muscles for Group B with comparatively higher CI during EDT condition than ST condition. Higher value of CI was observed in flexor muscles of the knee joints among Group A during EDT conditions, in contrast, higher CI in the extensor muscles was observed among Group B during ST conditions. In conclusion, the study confirmed that erratic-dynamic movements of target could change the movement coordination pattern to maintain the joint stability of participants.  相似文献

Managing IT-enabled transformation in the public sector: A case study on e-government in South Korea     

Hyun Jeong Kim  Gary Pan  Shan Ling Pan 《Government Information Quarterly》2007

The implementation of e-government is a burgeoning phenomenon across the globe. It improves and enhances the infrastructures and services provided to the citizens. However, a review of the IS literature reveals that research on the implementation of e-government is rather limited, which could be due to the general misconception of the public sectors as rigid and risk-averse establishments. The shortage of studies on e-government’s implementation presents a knowledge gap that needs to be plugged. This gap is significantly amplified by the increasing number of e-government initiatives being implemented by governments in recent years. This paper describes and analyzes South Korea’s Supreme Court Registry Office, which has implemented e-government. The case study discusses practical implications and suggests future research areas. Findings of the study include the alignment of technology and business processes, integration of resources into core business activities, integrating stakeholders’ trust and commitment, and better understanding of the role of organizational learning, which can enhance the adoption and institutionalization of e-government initiatives.  相似文献   

Differences between the sexes in the three-dimensional angular rotations of the lumbo-pelvic-hip complex during treadmill running     

Schache AG  Blanch P  Rath D  Wrigley T  Bennell K 《Journal of sports sciences》2003,21(2):105-118

The aims of this experiment were to determine whether there are differences between the sexes in the three-dimensional angular rotations of the lumbo-pelvic-hip complex during running and, if such differences exist, to establish whether factors other than sex can explain the observed differences. A cohort of 44 non-injured runners (22 males, 22 females) who usually ran more than 20 km per week were voluntarily recruited. All trials were conducted on a treadmill at a running speed of 4.0 m x s(-1). Reflective markers were placed over specific anatomical landmarks of the thoraco-lumbar spine, pelvis and femur. Data were captured using a VICON motion analysis system. Females tended to display a greater peak-to-peak oscillation for most of the angular rotations. An offset was the main difference between the male and female group mean waveforms for pelvis anterior-posterior tilt. Forward stepwise regression analysis revealed that sex was the most common variable related to the amplitudes of the angular rotations. Given these results, sport scientists conducting future biomechanical studies using angular data to test hypotheses are advised to be extremely cautious about averaging across male and female participants.  相似文献   

Improving document clustering in a learned concept space     

Jean-François Pessiot  Young-Min Kim  Massih R. Amini  Patrick Gallinari 《Information processing & management》2010

Most document clustering algorithms operate in a high dimensional bag-of-words space. The inherent presence of noise in such representation obviously degrades the performance of most of these approaches. In this paper we investigate an unsupervised dimensionality reduction technique for document clustering. This technique is based upon the assumption that terms co-occurring in the same context with the same frequencies are semantically related. On the basis of this assumption we first find term clusters using a classification version of the EM algorithm. Documents are then represented in the space of these term clusters and a multinomial mixture model (MM) is used to build document clusters. We empirically show on four document collections, Reuters-21578, Reuters RCV2-French, 20Newsgroups and WebKB, that this new text representation noticeably increases the performance of the MM model. By relating the proposed approach to the Probabilistic Latent Semantic Analysis (PLSA) model we further propose an extension of the latter in which an extra latent variable allows the model to co-cluster documents and terms simultaneously. We show on these four datasets that the proposed extended version of the PLSA model produces statistically significant improvements with respect to two clustering measures over all variants of the original PLSA and the MM models.  相似文献   

Examining the Causal Relationships Among Selected Antecedents of Responsible Environmental Behavior     

Yeong-Hyeon Hwang  Seong-Il Kim  Jiann-Min Jeng 《The Journal of environmental education》2013,44(4):19-25

Abstract

Attitude models have been widely applied to natural resource management to ensure responsible environmental behavior. For a variety of applications, the causality among selected antecedents, such as knowledge of environmental issues, locus of control, attitude, personal responsibility, and intention to act on responsible environmental behavior has not yet been tested empirically. A hypothesized causal model based on Hine's (1986) model on responsible environmental behavior was developed. The data from 523 visitors to the urban forest trail in the Kwang-Reung Arboretum, Korea, during September 1995 were used for testing the suggested causal model. Path analysis using the LISREL program tested the model fit and statistical effects of variables. In terms of the effects on intention to act, locus of control and attitude are more important than knowledge and personal responsibility. Our findings suggest that in order to enhance responsible environmental behavior, environmental education and interpretation systems need to focus on changing the internal locus of control. Several recommendations, limitations, and directions for future research are discussed.  相似文献   

Optoelectrofluidic field separation based on light-intensity gradients     

Sanghyun Lee  Hyun Jin Park  Jin Sung Yoon    Kwan Hyoung Kang 《Biomicrofluidics》2010,4(3)

Optoelectrofluidic field separation (OEFS) of particles under light -intensity gradient (LIG) is reported, where the LIG illumination on the photoconductive layer converts the short-ranged dielectrophoresis (DEP) force to the long-ranged one. The long-ranged DEP force can compete with the hydrodynamic force by alternating current electro-osmosis (ACEO) over the entire illumination area for realizing effective field separation of particles. In the OEFS system, the codirectional illumination and observation induce the levitation effect, compensating the attenuation of the DEP force under LIG illumination by slightly floating particles from the surface. Results of the field separation and concentration of diverse particle pairs (0.82–16 μm) are well demonstrated, and conditions determining the critical radius and effective particle manipulation are discussed. The OEFS with codirectional LIG strategy could be a promising particle manipulation method in many applications where a rapid manipulation of biological cells and particles over the entire working area are of interest.  相似文献   

A cross-cultural investigation of teachers’ and reporting officers’ self-ratings on teaching and leadership skills across Singapore and Bahrain     

Wee Pin Goh Jonathan  Lee Ong Kim  Hairon Salleh 《International Journal of Educational Research》2009,48(4):258-273

Self-rating bias is particularly likely in organizational behavior research as individuals tend to inflate their expertise, skills and character. This study aims to examine how two culturally diverse groups of teachers and their reporting officers respond to self-ratings of their own teaching skills and leadership skills respectively. It is posited that such response may be culturally based. To ensure validity of comparisons, analyses were done using linear Rasch measures in logits rather than the non-linear raw scores. No significant differences were found between the perceptions of Singaporean teachers and their reporting officers on teaching and leadership skills. The Bahraini data however revealed teachers’ perceptions of own teaching skills were significantly higher than that of their reporting officers. The opposite is true for the Reporting officers’ perceptions of our leadership skills. Bahraini teachers’ perceptions of their own teaching skills were also found to be significantly higher than that of their Singaporean counterparts. The findings support the notion that individuals’ thinking and behavior is influenced by how they process social and cultural information.  相似文献
