- 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.

- Space Based QoS Estimation, Storage Methodology and Meta Model of a Web
Abstract: Space Based QoS Estimation, Storage Methodology and Meta Model of a Web Service
Author Ravi Shankar PandeyPreeti Sing
Internet services have changed performance of the business organization to facilitate automation of business processes in the same organization or different organizations. These business processes are implemented by a web service or set of web services. These services are going to be composed automatically. These automatic compositions may suffer from failures. These failures may be occurred due to functional dissimilarity or non-functional requirement which are also called as Quality of service attributes (QoS). These QoS attributes contribute in service selection to minimize the service failures. These QoS attributes are either time based/space based. The space based Qos attribute is location affinity and is also responsible in failure of service composition. These QoS attributes (time based/space based) can be estimated from the history of the usage of web services. In this paper, we have proposed a model which computes the space based QoS attribute (location affinity) from the usage history of the web service which contains information about location. We have proposed a probabilistic model which is based on Hidden Markov Model (HMM) which includes the role of the hidden states of the web service in computation of a location affinity (Space based QoS attribute). We have also argued that this location affinity is not a single value but it is a list. These set of values of a location affinity are stored in a proposed data structure which we have called as Affinity Tree. We have presented an algorithm for computing affinity of the cluster. A Meta model of a web service which includes space based affinity is also proposed. We are describing all our proposals using an example.
- Study on the Influence of Game Behaviors Towards Classroom Learning
Abstract: Study on the Influence of Game Behaviors Towards Classroom Learning
Author Junmin YeZhifeng WangYu YiZhixin LiaoShu ChenWei ZhouRong L
Game is an important part of the learners’ extracurricular activities and can affect their learning performances. Based on learning analytics theory, this research is the qualitative analyses of learners’ game behavioral data, from which the quantized learner model is built to analyze the influence of learners’ game behavior on their learning performances. The model was compared with the effect of the later teaching to prove the feasibility and reliability of the research methods. This research proposed the quantization method of the influence of learners’ game behavior on their learning performances through the learner model. According to the analysis of the differences between learners, teachers can provide personalized recommendations for them in order to get better teaching results.
