Abstract

The development of network technology increases the amount of information on the Internet, how to obtain the information from these massive useful and effective automation technology resources become a problem to be resolved. In this paper we firstly introduce the working principle of HTML Parser and Java-related regular expression knowledge, then a general unstructured documents for metadata automatically extracted model is set up, the model is mainly for semantic features,combining with page layouts, text messaging, logic and other information has good field adaptation and language adaptation.

Abstract

Along with the vigorous development of streaming media technology, synchronized multi-media courseware is widely used in education domain. However, during the recording process of the courseware, automatic generation of the content navigation becomes a difficult problem. In this paper, we do an in-depth research on the automatic generation of multimedia courseware content navigation based on XML; propose a PPT (Power Point) heading automatic extraction algorithm and matching strategy of synchronization information. We realize the automatic generation of multimedia courseware content navigation by an instance. The result shows that this method can solve the content navigation generation problem and effectively reduce the labor intensity of development of multimedia courseware.

Abstract

Technology, pedagogy, and content knowledge (TPACK) has been considered as a promising theoretical framework to guide teacher educators in designing and developing in-service K12 teacher education programs. However, it seems unclear whether in-service teachers have different TPACK perceptions when entering the education programs. This study surveyed the TPACK perceptions of 2,728 Chinese in-service K12 teachers. A questionnaire adapted from Koh, Chai, and Tsai’s survey was validated by reliability and validity tests. Exploratory factor analysis revealed that Chinese in-service K12 teacher’s TPACK perceptions could be grouped into five scales. Analyses of means and standard deviation of all the variables of the TPACK construct to examine Chinese in-service K12 teachers’ TPACK perceptions showed that teachers had rated themselves as slightly above five points for all the variables. Independent sample t tests to examine the relationships between in-service K12 teachers’ gender and the TPACK variables indicated that male teachers rated themselves higher than female teachers for the variable content knowledge (CK) and lower for the variable pedagogical content knowledge. F tests to examine the relationships between in-service K12 teachers’ years of service and the TPACK variables revealed that young in-service K12 teachers tended to perceive better in the capacities of applying technology and worse in the capacities of teaching method and subject matter. Hierarchical regression analysis to explore which variables (technological knowledge, pedagogical knowledge, CK, pedagogical content knowledge, technological content knowledge, and technological pedagogical knowledge) could predict the variable of TPACK showed that in-service K12 teachers’ perceptions of pedagogical knowledge, technological knowledge, and CK had the largest positive effect on the TPACK variable.

198. ERDRM: A Digital Rights Management System Model for Educational Resources.

Author

Wang, Shujuan and Liu, Qingtang

Abstract

The intellectual property protection problem has been an obstacle to restrict the development of distance education. Enhancing the intellectual property protection of educational resources will make great realistic significance in improving quality of distance education. DRM provides technological support to the intellectual property protection in distance education. In the first part of this paper, we introduce the current situation of DRM technology and its fundamental features. And then, through analysis of the special demands of the educational field and contrastive study of security technology available currently, we bring forth the ERDRM, a digital rights management system model for educational resources.

199. Research on Learning Resources Organization Model.

Author

Liu, Qingtang and Sun, Zhimei

Abstract

The paper studies the adaptive learning content organization model and algorithm, which takes knowledge point as a unit. At first, it defines granularity of learning object, designs learning content level framework, which takes knowledge point as the meaning unit, builds up the reusable and sharable foundation of learning resources. The second is to provide the basic scheduling model for learning content organization. The model involves in pre-test, survey, knowledge point scheduling modules, summary, and post-test. Learning content scheduling algorithm is designed to choose learning content according to the learning content sequence, learner΄s styles, learning evaluating outcomes and application context. Lastly, the scheduling algorithm is proved effectiveness and stable in E-learning Service Platform. [ABSTRACT FROM AUTHOR]
