功能语境论及其教学设计意蕴     

钱旭鸯 《现代教育技术》2008,18(6):8-12

当前,哲学思考已开始成为教学设计的前提假设,而功能语境论是新近出现于心理学中的一种哲学观点,对教学设计具有多方面潜在贡献。通过对功能语境论的语境论世界观基础和行为分析表现形式的简要介绍,分别阐述了功能语境论对教学设计理论基础、教学设计实践取向和教学设计研究方法等方面的影响,并在此基础上进行了分析和讨论,从而明晰了功能语境论对教学设计价值取向等方面的哲学关照和反思。  相似文献

VisualFoxpro中数据库链接实验与研究     

李斌 《延安教育学院学报》2008,22(1):69-72

在VF教学中发现使用数据库链接向导建立的查询或视图,由于链接数据表操作的顺序不同,而结果不同。经实验发现是由于查询语言的变化而导致结果的差异,经分析,VF中数据库链接顺序可分为直线型、汇聚型、分散型、反插型、环型,只有前两种是正确的链接方式。  相似文献   

A new approach to test score equating using item response theory with fixed C-parameters     

Guemin Lee  Anne R. Fitzpatrick 《Asia Pacific Education Review》2008,9(3):248-261

Because parameter estimates from different calibration runs under the IRT model are linearly related, a linear equation can convert IRT parameter estimates onto another scale metric without changing the probability of a correct response (Kolen & Brennan, 1995, 2004). This study was designed to explore a new approach to finding a linear equation by fixing C-parameters for anchor items in IRT equating. A rationale for fixing C-parameters for anchor items in IRT equating can be established from the fact that the C-parameters are not affected by any linear transformation. This new approach can avoid the difficulty in getting accurate C-parameters for anchor items embedded in the application of the IRT model. Based upon our findings in this study, we would recommend using the new approach to fix C-parameters for anchor items in IRT equating.

熵权法在银行经营绩效综合评价中的应用   总被引：58，自引：1，他引：58  

谢赤  钟赞 《中国软科学》2002,(9):108-110,107

针对在通常所采用的加权综合评价法中人为确定权重的缺陷，本文根据所构建的综合评价指标体系，通过将熵权系数法应用于非国有独资银行经营绩效的综合评价，得出了具有较强实际意义的结论。并认为熵权法这种根据指标数据提供的信息量客观赋权方法是一种在实际应用中简单可行的科学方法。  相似文献   

Investigating negative reviews and detecting negative influencers in Yelp through a multi-dimensional social network based model     

《International Journal of Information Management》2021

In this paper, we propose an investigation of negative reviews and define the profile of negative influencers in Yelp. The methodology adopted to achieve this goal consists of two phases. The first one is theoretical and aims at defining a multi-dimensional social network based model of Yelp, three stereotypes of Yelp users, and a network based model to represent negative reviewers and their relationships. The second phase is experimental and consists in the definition of five hypotheses on negative reviews and reviewers in Yelp and their verification through an extensive data analysis campaign. This was performed on Yelp data represented by means of the models introduced during the first phase. Its most important result is the construction of the profile of negative influencers in Yelp. The main novelties of this paper are: (i) the definition of the two social network based models of Yelp and its users; (ii) the definition of three stereotypes of Yelp users and their characteristics; (iii) the construction of the profile of negative influencers in Yelp.  相似文献   

From Love at First Sight to Soul Mate: The Influence of Romantic Ideals in Popular Films on Young People's Beliefs about Relationships     

《Communication monographs》2012,79(2):150-175

Despite their popularity, few studies have systematically investigated the content of romantic comedy movies or the effects they may have on viewers. We conducted two studies to address this gap. The first study was a content analysis of the romantic ideals embedded in the top 52 highest grossing romantic comedies from the last 10 years. Results demonstrated that romantic ideals and challenges are prevalent in these films. The second study was a large-scale survey of 335 undergraduate students, who were asked to report on their romantic comedy movie viewing and beliefs about romance. Results showed that individuals who watched these films in order to learn reported stronger endorsement of romantic ideal beliefs than those who did not watch to learn.  相似文献
