Emotion recognition and communication for reducing second‐language speaking anxiety in a web‐based one‐to‐one synchronous learning environment     

Chih‐Ming Chen  Tai‐Hung Lee 《British journal of educational technology : journal of the Council for Educational Technology》2011,42(3):417-440

e‐Learning is becoming an increasingly popular educational paradigm because of the rapid growth of the Internet. Recent studies have argued that affective modelling (ie, considering a learner's emotional or motivational state) should also be considered while designing learning activities. Many studies indicated that various learning emotions markedly impact learning outcomes. In the language education field, many studies have investigated anxiety associated with learning a second language, noting that anxiety has an adverse effect on the performance of those speaking English as a second language. Therefore, how to reduce anxiety associated with learning a second language to increase learning performance is an important research issue in the language education field. Accordingly, this study employed a sensor, signal processing, wireless communication, system‐on‐chip and machine‐learning techniques in developing an embedded human emotion recognition system based on human pulse signals for detecting three human emotions—nervousness, peace and joy—to help teachers reduce language‐learning anxiety of individual learners in a web‐based one‐to‐one synchronous learning environment. The accuracy rate of the proposed emotion recognition model evaluated by cross‐validation is as high as 79.7136% when filtering out human pulse signals that have bias. Moreover, this study applied the embedded emotion recognition system to assist instructor's teaching in a synchronous English conversation environment by immediately reporting variations in individual learner emotions to the teacher during learning. In this instructional experiment, the teacher can give appropriate learning assistance or guidance based on the emotion states of individual learners. Experimental results indicate that the proposed embedded human emotion recognition system is helpful in reducing language‐based anxiety, thus promoting instruction effectiveness in English conversation classes.  相似文献   

Characteristics of child abuse homicides in the state of Kansas from 1994 to 2007     

Kajese TM  Nguyen LT  Pham GQ  Pham VK  Melhorn K  Kallail KJ 《Child abuse & neglect》2011,35(2):147-154

Objective

This study described the epidemiology of child abuse homicides in the state of Kansas from 1994 to 2007. It focused on obtaining significant details on all recorded child abuse homicides in Kansas during this time frame to provide critical information that can be used for future preventive measures.

Methods

A retrospective case review was conducted on data gathered by the Kansas State Child Death Review Board for all cases of “child abuse homicides” that occurred from 1994 to 2007.

Results

A total of 170 child abuse homicide cases in Kansas between 1994 and 2007 were identified. The majority of these cases (63.5%) were considered fatal child physical abuse. There was a predominance of female victims (55.9%). The vast majority of victims were White (78.8%), followed by Black (17.1%). One to 2-year-olds accounted for the largest age group of children who were victimized (33.5%). For cases with known prenatal care status, 74% of mothers received adequate prenatal care. The largest percentage of victims was children of single mothers (40.6%), with no prior history of child abuse (60%). The majority of deaths occurred in the victim's residence (81.8%). The greatest number of deaths occurred secondary to abusive head trauma (42.9%), followed by asphyxia (21.8%). When a trigger was known, 44.2% involved inconsolable crying. The most common perpetrator was the victim's biological father (26.6%), followed by the victim's biological mother (24.9%), then the victim's mother's male paramour (19.8%).

Conclusions

Familiarity with characteristics involved in child abuse homicide allows for opportunities to enlist important preventive measures. Most child abuse homicides occurred at the hands of the victim's biological parents and in the victim's own residence. Prevention should be focused on parent education and coping mechanisms for the frustrating features of crying in normal infants that lead to shaking or abuse.  相似文献   

Design and usability assessment of a dialogue‐based cognitive tutoring system to model expert problem solving in research design          下载免费PDF全文

Wei‐Chen Hung  Thomas J. Smith  M Cecil Smith 《British journal of educational technology : journal of the Council for Educational Technology》2015,46(1):82-97

Technology provides the means to create useful learning and practice environments for learners. Well‐designed cognitive tutor systems, for example, can provide appropriate learning environments that feature cognitive supports (ie, scaffolding) for students to increase their procedural knowledge. The purpose of this study was to conduct a series of usability tests of a dialogue‐based design framework for the presentation of domain knowledge and assess how it can be used to actively engage learners in learning about research methods. Three formal usability assessments and an instructor adoption assessment were conducted during the development of the tutoring system. Each usability assessment employed diverse data collection methods to ensure broad and in‐depth coverage of findings. The findings revealed that the dialogue metaphor enabled natural and participatory interactions between the system and users. The feedback prompts or hints and support resources provided opportunities for learning during the process of problem solving. Future research to extend the support of usability assessments is also discussed.  相似文献   

Adjunct Faculty Characteristics That May Predict Intention to Integrate Technology Into Instruction     

Jonathan Paver  Wei-Chen Hung 《Community College Journal of Research & Practice》2013,37(10):859-872

This study examined the demographic factors that predict intention to integrate technology into instruction by community college adjunct faculty. Regression model findings indicated that the demographic characteristics of years of teaching experience, teaching discipline, hours of preparation time, and years of experience using computers were predictors of intention to integrate technology. Other literature-based characteristics such as age, gender, and participation in professional development activities, although not noted predictors in the current study, still warrant further examination to provide additional insight into their potential ability to predict technology use by community college adjunct faculty.  相似文献   

Seeing the landscape and the forest floor: changes made to improve the connectivity of concepts in a hybrid problem-based learning curriculum     

Geraldine O'Neill  Woei Hung 《Teaching in Higher Education》2013,18(1):15-27

Problem-based learning (PBL) curricula utilise authentic problems that are based in the real-world of practice. This very characteristic enables students to develop an intimate knowledge about the intricacies of practice, metaphorically, seeing the details of the forest floor. However, it is equally important for students to develop an overall conceptual framework of the curriculum and understand how the different aspects of the subject domain relate to each other, i.e. seeing the landscape. This paper explores the extent to which these two aspects of curriculum design, in particular the landscape, were achieved in an ‘Education Theories’ module for lecturers in higher education. It utilises Hung's 3C3R problem-design model to help develop these connections. The findings alert curriculum designers to pay more focused attention to the holistic problem from Hung's model and the model's relationship with other learning resources (lectures, etc.) in supporting connectivity in PBL hybrid curricula.  相似文献

The adaptation of Chinese international students to online flexible learning: two case studies     

Rainbow Tsai‐Hung Chen  Sue Bennett  Karl Maton 《Distance Education》2008,29(3):307-323

The cross‐cultural experiences of Chinese international students in Western countries have been subject to intensive research, but only a very small number of studies have considered how these students adapt to learning in an online flexible delivery environment. Guided by Berry’s acculturation framework (1980 Berry, J.W. 1980. “Acculturation as varieties of adaptation”. In Acculturation, theory, models, and some new findings, Edited by: Padilla, A. 9–25. Boulder, CO: Westview Press.  [Google Scholar], 2005 Berry, J.W. 2005. Acculturation: Living successfully in two cultures. International Journal of Intercultural Relations, 29(6): 697–712.  [Google Scholar]), the investigation discussed in this article aimed to address this gap by exploring the adaptation processes of Chinese international students to online learning at an Australian university. This article reports on the challenges perceived by two students from Mainland China, their coping strategies, changes in their opinions of online learning, and their respective patterns of adaptation. By presenting two indicative case studies drawn from a wider study, this article aims to demonstrate the use of Berry’s concepts as a means to frame such studies.  相似文献   

The green waves of environmental sustainability in sport     

Brian P. McCullough  Michael E. Pfahl  Sheila N. Nguyen 《Sport in Society》2016,19(7):1040-1065

The purpose of this paper is to provide a conceptual framework surrounding the typology of environmental sustainability efforts made within the sport industry. We draw from multiple theoretical frameworks (i.e. institutional theory and diffusion of innovation) to understand the increased similarities of environmental sustainability efforts through organizational learning as environmental sustainability efforts become more purposeful and sophisticated across the sport industry. The paper uses examples from various sport organizations and leagues to classify the efforts of sport organizations into waves of sport environmental sustainability efforts and important implications arising from them.  相似文献   

Self-report measures of the home learning environment in large scale research: Measurement properties and associations with key developmental outcomes     

Frank Niklas  Cuc Nguyen  Daniel S. Cloney  Collette Tayler  Raymond Adams 《Learning Environments Research》2016,19(2):181-202

Favourable home learning environments (HLEs) support children’s literacy, numeracy and social development. In large-scale research, HLE is typically measured by self-report survey, but there is little consistency between studies and many different items and latent constructs are observed. Little is known about the stability of these items and constructs over time when used in either longitudinal research or studies with children with a wide range of ages. A review of the literature shows commonalities and differences between approaches in research on HLE. When we tested the psychometric properties of a short-form measure of HLE with a Rasch item-response-model using longitudinal data from over 1600 Australian families, there was support for two dimensions of HLE—formal and informal learning frequency. We found that this measure was stable over the transitional period from pre-K to school as well as between gender and family language background. There were small but significant associations between the HLE measures and cognitive and behavioural developmental outcomes. We recommend that other measures of HLE could be similarly validated to assess their suitability for use in longitudinal research on learning environments. Recommendations are made for the future development of measures of broader constructs of the HLE.  相似文献   

Key Problems in Organizing and Structuring University Research in Vietnam: The Lack of an Effective Research “Behaviour Formalization” System     

Huong Thi Lan Nguyen  Vincent Lynn Meek 《Minerva》2016,54(1):45-73

Structure and organization seems to be at the root of many of the questions raised about institutional behaviour; however, with respect to research on university capacity building, few studies have examined research organizational problems, particularly in developing countries. This study investigates academic reactions to the structure and organization of research at four leading Vietnamese universities. Through document analysis and semi-structured interviews with 55 participants, the study finds that the four case-study Vietnamese universities have accomplished a number of the more visible tasks of research management such as creating research and research management positions; deciding primary organizational units for research delivery; creating a research office; and creating research oversight committees. However, they seem to neglect the other less visible tasks of organizing and structuring research such as developing rules for research integrity; developing a mechanism for evaluating the quality of research outcomes; preparing researchers and research managers for the necessary skills and knowledge; and deciding vertical and horizontal decentralization. The study concludes that even though research has been formally structured and organized, the management of research has not yet been professionalized. The key problem in organizing and structuring research is the lack of an effective system for research behaviour formalization. A more effective system for better formalizing research behaviours should be developed so that Vietnamese universities can integrate more successfully into the global research.  相似文献
