Comparative investigation of the psychometric properties of three tests of logical thinking     

Kapur S. Ahlawat  Victor Y. Billeh 《科学教学研究杂志》1987,24(2):93-105

Using a sample of 908 eleventh grade science stream male and female students from similar socioeconomic area schools, variance based psychometric properties of three paper-and-pencil tests of logical thinking (Longeot test, Lawson's test TOFR, and Tobin and Capie's test TOLT) are investigated. A sub-sample of 212 students took the three tests in randomly allocated different sequential orders of presentation, while 696 students took only two tests. Alfa coefficients for each test separately and for the three tests combined together, concurrent validity coefficients, measures of item difficulty, item discrimination, item-criterion correlation, and 30-day stability coefficients are calculated. Considering the relative homogeneity of the sample, the reliability coefficients of the tests are judged satisfactory, but concurrent validity coefficients are quite low which implies incongruency in decisions made on the basis of the three tests. Need for estimating various psychometric parameters of alternative tests of logical thinking over different grade populations is emphasized.  相似文献   

The role of learners’ epistemic beliefs in an online Community of Inquiry     

Kun Huang  Victor Law  Sang Joon Lee 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(4):1882-1895

The Community of Inquiry (CoI) model provides a lens to examine online learning through three elements: teaching presence (the design and facilitation of learning experiences), social presence (the extent to which learners project themselves as real people) and cognitive presence (the extent to which learners are able to construct meaning through inquiry and reflection activities). While research to date has established the importance of these essential presences in online learning environments, recent research on the CoI model calls for the need to explore the role of learner characteristics. The current study responded to the call by examining the role of learners’ epistemic beliefs (EB) (ie, individuals’ fundamental beliefs about the nature of knowledge and knowing) in an online CoI. Multiple linear regressions analyses revealed that EB moderated the relationship between learners’ perceived teaching presence and cognitive presences. Future studies on CoI should take learners’ epistemic beliefs into consideration, especially in the case of low teaching presences. Theoretical and practical implications for designing and investigating online learning are discussed.  相似文献   

Czechoslovakia: From revolution to reconstruction     

Victor J. Drapela 《International journal for the advancement of counseling》1992,15(2):79-89

As one of the countries in east-central Europe liberated in 1989 from Communist rule, Czechoslovakia is currently undergoing profound social, political, and economic changes. This article presents both the positive outcomes of the velvet revolution and a variety of problems that the country has to cope with. Of particular concern are three problem areas: the legacy of Communist rule, the unsettled relationship between Czechs and Slovaks, and the ruined national economy. Of the three problem areas, the latter is considered most painful, since it involves layoffs and thus directly affects the lives of individuals and families. The article reviews administrative initiatives undertaken by the government to modernize production and minimize unemployment. It also focuses on the changing role of helping professionals in Czechoslovakia. By reasserting their true mission-assist people rather than manipulate them-helping professionals can promote significant attitudinal changes in their society.  相似文献   

Self-regulation as a function of perceived leadership and cohesion in small group online collaborative learning     

Kui Xie  Lauren C. Hensley  Victor Law  Zhiru Sun 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(1):456-468

The present study examined the relationships between perceived leadership, group cohesion, online engagement, self-regulation and learning outcomes. Data included surveys and online discussion logs from 171 students in an undergraduate online course. Through correlation analysis and structural equation modeling, the results revealed unique contributions of task and relationship leadership in small group collaborative learning. Each form of leadership may translate into greater use of self-regulation strategies that align with students’ focus on either the instrumental or interpersonal resources related to academics but may bring about a corresponding lower utilization of other types of self-regulation strategies. Further, results indicate that students’ perceptions of group cohesion provided the most robust and multifaceted positive associations with learning engagement.  相似文献   

移动学习的案例研究及内容分析——以mGage项目为例   总被引：1，自引：1，他引：0  

王敏娟  Toni Barone  Scott Simpson  Victor Leister 《现代教育技术》2011,21(8):14-19

文章首先对移动学习在中小学课堂中的应用、移动学习的形式和信息设计进行了文献综述。在此基础上,又对美国圣地亚哥州立大学教育技术系开展的mGage项目进行了案例分析。研究者设计出一套详细的评价工具,从视觉吸引力、认知过程、资源质量等16个维度评估学生的WebQuest作品。结果显示,参加移动学习的实验组的得分明显高于对照组。统计分析表明,使用移动设备进行学习的实验组,除了在工具使用维度上具有明显优势外,在认知过程维度和资源质量维度的得分也胜过对照组。文章最后对研究进行了反思总结并展望了下一阶段的研究工作,以期为移动学习进入中小学课堂提供有意义的借鉴。  相似文献   

Visual events and electronic government: What do pictures mean in digital government for citizen relations?     

Victor Bekkers  Rebecca Moody 《Government Information Quarterly》2011,28(4):457-465

E-government is becoming more picture-oriented. What meaning do stakeholders attach to visual events and visualization? Comparative case study research show the functional meaning primarily refers to registration, integration, transparency and communication. The political meaning refers to new ways of framing in order to secure specific interests and claims. To what the institutional meaning relates is ambiguous: either it improves the position of citizens, or it reinforces the existing bias presented by governments. Hence, we expect that the emergence of a visualized public space, through omnipresent penetration of (mobile) multimedia technologies, will influence government–citizen interactions.  相似文献   

Organizing and implementing the internship component of undergraduate programs in IS Security     

Victor Ralevich  Dragana Martinovic 《Education and Information Technologies》2012,17(1):27-48

This paper describes experiences in organizing and running an internship component of an undergraduate program in information systems security. In 2004, Sheridan College Institute of Technology and Advanced Learning introduced a novel Bachelor in Applied Information Sciences (Information Systems Security) program. The intent was to educate well-rounded specialists in the field and provide them with valuable work experience during the 8-month long co-op term. The research presented here is based on the co-op officer reports, statistics reported by the co-op office, interviews with the students and other anecdotal data mainly collected through conversations with the involved parties. Besides providing facts that speak to the quality of the program and appropriate organization of the job placements, the authors critically examine successes and challenges encountered in this process. Comparison with other information systems security postsecondary programs in Ontario, Canada, is given based on type of program, characteristics and focus of curriculum content and length of internship.  相似文献

Using Technology-Enhanced Inquiry-Based Instruction to Foster the Development of Elementary Students’ Views on the Nature of Science     

Schellinger  Jennifer  Mendenhall  Anne  Alemanne  Nicole  Southerland  Sherry A.  Sampson  Victor  Marty  Paul 《Journal of Science Education and Technology》2019,28(4):341-352

The Next Generation Science Standards support understanding of the nature of science as it is practiced and experienced in the real world through interconnected concepts to be imbedded within scientific practices and crosscutting concepts. This study explored how fourth and fifth grade elementary students’ views of nature of science change when they engage in a technology-enhanced, scientific inquiry-oriented curriculum that takes place across formal and informal settings. Results suggest that student engagement in technology-enhanced inquiry activities that occur in informal and formal settings when supported through explicit instruction focused on metacognitive and social knowledge construction can improve elementary students’ understanding of nature of science.

UNIVERSITY LIBRARIES AND INTERDISCIPLINARY STUDY IN THE COMPUTER AGE     

Victor‐Emanuel Sahini 《Higher Education in Europe》1989,14(4):21-23

Through increasingly sophisticated computerization, libraries will evolve from being passive depositories of published materials to becoming dynamic information systems. Stored information will be analyzed and recoinbined in original ways which are similar to the processes occurring on the frontiers of disciplines which are giving rise to new combined disciplines: Thus the partnership of computerized information systems and interdisciplinary scientific research will vastly widen the frontiers of human discovery.  相似文献
