This proposal discusses the issues and dilemmas about the curriculum implementation in the EFL （English as a foreign language） education in China’s middle-schools and examines the nature of integrated contend-based （ICB） instruction by providing its rationale, definition, evolution, and delivery, and based on the above, it explores an excellent venue that the ICB could provide for Chinese student’s EFL learning and calls for the application of the curriculum of ICB into the EFL instruction in China’s secondary education.展开更多

However, the ranking result always has a big deviation with actual rank for the existence of unknown web traffic, which cannot be identified accurately under current techniques. In this paper, we introduce a novel method to approximate the actual rank. This method associates unknown web traffic with websites according to statistical probabilities. Then, we construct a probabilistic top-k query model to rank websites. We conduct several experiments by using real HTTP traffic traces collected from a commercial ISP covering an entire city in northern China. Experimental results show that the proposed techniques can reduce the deviation existing between the ground truth and the ranking results vastly. In addition, we find that the websites providing video service have higher ratio of unknown IP as well as higher ratio of unknown traffic than the websites providing text web page service. Specifically, we find that the top-3 video websites have more than 90% of unknown web traffic. All these findings are helpful for ISPs understanding network status and deploying Content Distributed Network(CDN).展开更多

This research is on body function training on volleyball teaching methods of this technology in the project, the function of training system into the volleyball technique teaching, through the method of experimental teaching method to verify the function of training to the technical level of the student volleyball has been effectively improved.展开更多

RAs were coded and analyzed by four analysts to identify their content of research, research methods, and statistical procedures. It was found that there has been an increase in the number and the average length of articles. The average length has been on the rise from 8.09 pages in 1976-1985 to 14.38 during 2006-2015. The extensive review of the RAs also revealed a broad range of themes that belonged to 34 research domains. SLA, Technology 8： Language Learning, Language Teaching Methodology, Language Testing, and Psycholinguistics were the most widely researched areas. The qualitative method with 33.97% was the dominant research method in the journals. Regarding the statistical techniques, it was illustrated that descriptive statistics, Pearson correlation, ANOVA, and t-test were the most commonly used procedures in the applied linguistic RAs.展开更多
