- ICT in the Curriculum of an Early Childhood Education University
Abstract: ICT in the Curriculum of an Early Childhood Education University Department
Author Jim Prentza
Early childhood teachers as teachers in all levels of education use software for productive, learning, teaching and management tasks. The curriculum of university departments educating early childhood teachers includes courses providing background to ICT as well as to its integration in education. This paper first outlines the role of free open-source software and cloud computing in education and main categories of software useful to early childhood teachers. Furthermore, an outline of ICT curriculum in a university department of early childhood education is discussed. Lab activities are based on a combination of free open-source software and visual programming environments available from higher education institutes at no cost. Planning of activities took into consideration students’ previous knowledge, available hardware and learning goals. Feedback from students and their responses to questionnaires are promising. To the best of the author’s knowledge, such issues involving the education of pre-service teachers have not been thoroughly discussed till now.
- Scheduling of Multiple Applications in Wireless Sensor Networks Using
Knowledge of Applications and Network
Abstract: Scheduling of Multiple Applications in Wireless Sensor Networks Using Knowledge of Applications and Network
Author Navdeep Kaur KapoorShikharesh MajumdarBiswajit Nand
This paper presents a simulation based investigation of scheduling on wireless sensor networks hosting multiple applications. The applications vary in terms of their resource requirements such as the number of sensors required by the applications and the location of the required sensors relative to a sink node. The requests for the various applications need to be scheduled in a manner so as to reduce the overall mean response time to the users of the applications. This paper proposes scheduling algorithms that combine the knowledge of the characteristics of applications and the system in order to make a scheduling decision. Simulation experiments demonstrate that such algorithms provide a better performance than the knowledge free First Come First Served (FCFS) algorithm. Simulation results show that communication delays play a significant role in determining the overall mean response time in a WSN; and a scheduling algorithm that allocates a higher weight to higher hop distances of sensors from the cluster head provides the best performance.
- Research of the Social Comment Data Emotional Tendency Based on Object
Select SVM-Text Sentiment Model
Abstract: Research of the Social Comment Data Emotional Tendency Based on Object Select SVM-Text Sentiment Model
Author Wenxin HuLiang H
In the study of hits of the drama, the useful of the social comment data is more and more important. But the most research concentrated on the volume or the kinds of the social data. The research of the emotional tendency indicated from the social date is insufficient. In this paper, we demonstrate that (1) because of the difference between drama social comment data and other comment, it’s necessary to build an emotional vocabulary for it; (2) confirming the object of the comment can improve the accuracy of result; (3) the emotion reverse is common in social comment data, it affects the real emotional tendency; (4) positive and negative words play different roles in the comment, they should be treated with different weight. In consideration of all the features extracted from Social comment data, we use the model of object Select SVM-Text Sentiment to get the accurate emotional tendency. Compared with the HowNet and NTUSD, the veracity is improved by 10% and 12% respectively; with confirming the comment object, the accuracy is improved nearly 7.1%; compared with the NBM and SVM,OSS-TS has the advantage of 14% and 15% respectively.
- Classroom Activities Design of Chinese Teaching to Foreigners Based on the
Flipped Classroom Model
Abstract: Classroom Activities Design of Chinese Teaching to Foreigners Based on the Flipped Classroom Model
Author Yanlan ShiJuan X
With the development and update of information technology, the flipped classroom has become a practical teaching method of education. It gives a new vitality in the educational reform. In this paper, the traditional structure of Chinese teaching to foreigners and the flipped structure are compared. Then four types of classroom teaching activities are designed based on the Learning Pyramid Theory and ancient Chinese learning methods. For achieving better teaching results, flipped classrooms are places of Chinese knowledge internalization, including using of knowledge and solving problems.
