基于UML和RUL设计高职院校教务管理系统的研究

随着职业化教育改革的不断推进,高校教务管理工作量大幅度增加,其复杂性也越来越大。这使得高校教务管理工作的信息化和网络化势在必行。与此同时,校园网的建立和Internet技术的引进为建立这样的系统提供了必要的条件。因此,该文针对高职院校的教务管理模式开发基于校园网的教务管理系统。该文使用UML统一建模语言和Rational统一过程对高职学院院校管理系统进行系统设计。在本论文中详细讨论的系统的需求分析,使用UML建模语言分析了管理系统的用例。以用例图为基础,进一步分析系统。使用对象图,协同图等表达系统对象之间的管理。开发系统的过程中,我们针对本系统客户端众多的特点,采用了以B/S模式为主,C/S模式为辅的开发模式。为了得到良好的伸缩性,结合COM+技术,采用三层体系结构开发。

“娱乐性”——动画艺术本质解读

动画通过夸张、风趣幽默的表现手法打破现实世界的既定框架,契合了人们对精神解放、自由的追求,表达了人们对美好生活的向往。娱乐性是动画作品诞生的原动力,是动画片尤其是商业动画片存在、成功的本质因素。我们应该颠覆"寓教于乐"中"乐"为途径"教"为目的旧观念,卸下中国动画背负了多年的沉重的教化功能这个包袱,轻松上路,让"娱乐"带领中国动画走得更远更好。     

Providing effective feedback, monitoring and evaluation to on-line collaborative learning discussions

Learning and knowledge building have become critical competences for people in the knowledge society era. In this paper, we propose a sociolinguistic dialogue model for understanding how learning evolves and how cognitive process is constructed in on-line discussions. The knowledge extracted from this model is used to assess participation behavior, knowledge building and performance. The ultimate purpose is to provide effective feedback, evaluation and monitoring to the discussion process. Seven hundred students from the Open University of Catalonia in Spain participated in this study. Results showed that learning and knowledge building may be greatly enhanced by presenting selected knowledge to learners as for their particular skills exhibited during interaction. In addition, this valuable provision of information is used as a meta cognitive tool for tutors and moderators for monitoring and evaluating the discussion process more conveniently. This contribution presents our conceptual model for interaction management as well as key design guidelines and evaluation results. Implications of this study are remarked and further research directions are proposed.

Ordinal regression by a gravitational model in the field of educational data mining

Educational data mining (EDM) is a research area where the goal is to develop data mining methods to examine data critically from educational environments. Traditionally, EDM has addressed the following problems: clustering, classification, regression, anomaly detection and association rule mining. In this paper, the ordinal regression (OR) paradigm, is introduced in the field of EDM. The goal of OR problems is the classification of items in an ordinal scale. For instance, the prediction of students' performance in categories (where the different grades could be ordered according to A ? B ? C ? D) is a classical example of an OR problem. The EDM community has not yet explored this paradigm (despite the importance of these problems in the field of EDM). Furthermore, an amenable and interpretable OR model based on the concept of gravitation is proposed. The model is an extension of a recently proposed gravitational model that tackles imbalanced nominal classification problems. The model is carefully adapted to the ordinal scenario and validated with four EDM datasets. The results obtained were compared with state‐of‐the‐art OR algorithms and nominal classification ones. The proposed models can be used to better understand the learning–teaching process in higher education environments.
