This study was conducted to explore the effects of computer-based modeling learning activates on sixth graders' modeling practices. The subjects of this study were 33 sixth graders in Taipei Taiwan. The experimental group received an instruction which was based on Model-It, a computer-based modeling tool, and a set of computer-based modeling learning activities. Paper and pencil tests of modeling...
The purpose of the study was to investigate digital divide issue among urban and rural k-12 schools in Chinese economically developed regions. The researchers selected three representative primary schools (one from urban area, one from rural area and one is located in urban area but all of its students are from rural area) to explore the issue. The study is quantitative by nature and random sampling...
This paper compares two different approaches, followed by our research group, to efficiently run NEPs on parallel platforms, as general and transparent as possible. The vague results of jNEP (our multithreaded Java simulator for multicore desktop computers) suggests the use of massively parallel platforms (clusters of computers). The good results obtained show the scalability and viability of this...
This meta-analysis employs a theoretical framework in quantitatively synthesizing empirical studies that investigate the effects of game-based learning versus classroom instruction on the student learning effect. Analyses of 14 journal papers with 21 studies on 946 students were conducted according to how media were used to support game-based learning. The results indicate that the effect sizes for...
In computer's word, the basic idea of DNA computing is using processing power of organic molecular information instead of digital switch components. In recent years, DNA computing has become one of (he important researches which solve complex problems. In this paper, in comparison with the analysis of the development of DNA computing, we introduce the working principle and mathematical model, and...
The traditional virtual biological behavior animation is realized by the key frame technology, but there are some deficiencies. Therefore, we propose the modeling of fish roe Based on artificial life method to animation fish roe using artificial life method and virtual reality technologies. It can animated the fish roe division without any of the key frames, not only has the basic characteristics...
This study evaluates the current state of electronic commerce (EC) research in China. The authors examine 275 articles in 18 journals acknowledged as the top journals of the field from 1998 to 2010. This study summaries some literatures and classification for EC. The authors present the four classifications which are research field, research objects, operational progresses and research methods. The...
To further enhance the safety of BIOS, this paper present a new trust BIOS verified and self-recovery model with USBKEY in Unified Extensible Firmware Interface (UEFI). This model established a trust chain from the first stage of UEFI to the operating system by analyzing the process of UEFI startup. Thus the model narrowed the scope of the root of trust and substantially imp roved the safety of the...
The purpose of this study was to explore the Civil Servants' use of the E-learning system of publics sectors continuance intention in Taiwan. It was to discuss the current use of E-learning for continuance intention behavior of the Civil Servants and impact on performance E-learning factor. Through the process of literature review, this study attempts to develop an integrated model based on the A...
It is widely recognized that the most critical part of knowledge management process is knowledge sharing. Knowledge sharing is crucial to either profit or non-profit organizations. The first part of this paper introduces the concept and some definitions of knowledge sharing. Next, the paper describes the benefits of knowledge sharing to the education. Based on the preliminary study and observation,some...
According to the current situation of multimedia instruction and application of campus network in new local colleges, this paper analyses problems and technical limitations in the process of implementing multimedia teaching; At the same time, combined with new requirements of multimedia instruction using network, it proposes the view that local colleges campus network should possess the ability of...
Much of our prior knowledge of information systems (IS) usage is based on its acceptance or continuance without understanding whether users are likely to use the IS or not. Prior models of IS usage provide a limited understanding of one's intention to use the IS, given that IS usage or continuance does not necessarily suggest the subsequent use of the IS. Even if people use particular IS, there is...
A single vendor single buyer integrated inventory optimization in supply chain for deteriorating items with shortage allowed is studied. The demand is supposed to be exponential time-varying and the buyer is allowed to backorder partially. The total inventory costs of vendor and buyer are explored respectively. An inventory model of the supply chain is developed accordingly to optimize the integrated...
In order to establish correlations with closed cup flash point (FP) and cold filter plugging point (CFPP) for biodiesel blending with diesel, FTNIR spectra of biodiesel blending with diesel and basic data obtained form standard methods are treated by partial least squares (PLS) and the relationship between these two indicators and mixing ratio are described initially in this paper. The method can...
Assembly language is a foundation courses for science and technology of computers. Computational thinking emphasizes just like computer scientists thinking. It is one of basic skills to solve problems with the computer technology. How to develop student's computational thinking is an urgent question in computer education. This paper analyzes the connotation of computational thinking, the embodiment...
With the rapid development of Internet, computer viruses has become more and more serious, which attract more and more people's attention. Therefore, the spread of computer viruses were probed in this study. The computer virus propagation model was established, and the spread of computer viruses in different time system status and development trend were simulated. In addition, computer viruses spread...
As the development of IT, information system (IS) become more and more important for commercial use in an Organization. Two models-Nolan's Stages of Growth Model and Three-Era Model are used to introduce how IS has changed and been used within an Organization. Then, McFarland's Strategic Grid which is a powerful tool for management to appraise the importance and the potential opportunities of IS is...
With quick upgrading of knowledge and high demand for all-round talents at the age of information, the integration of computer multimedia into college English course has altered traditional teaching model. The teaching focus is converted to learning process from content; teacher becomes the organizer and manager of class, the director and supervisor of students instead of the lecturer; students become...
Summary form only given. The computations of likelihood or posterior distribution of parameters of complex population genetics models are common tasks in computational biology. The numerical results of these approaches are often found by Monte Carlo simulations. Much of the recent work of Monte Carlo approaches to population genetics problems has used pseudorandom sequences. This paper explores alternatives...
This study utilized the Souza's semiotic engineering theory of HCI to user interface metaphors. The main aim of using Metaphors is the ability to determine the potential meaning in ongoing cognitive activities. The data were collected through the “Icon Recognition Test” and the interview questions. In addition, the users' navigation through Mac and Win7 operating systems include certain categories...
