This need is equally important for students as well as for young professionals. Access and training to all scientific information is necessary to ensure success in their future careers. Today, e-learning has become a common medium for the management and distribution of on-line educational content. Learning Management Systems （LMSs） were not only developed to handle a large variety of multimedia content that provides an organized knowledge repository used to accelerate access to information and skill acquisition; but, LMSs can also keep detailed statistics on the use of the available material offering a powerful training and educational tool. In this document, the Petroleum Knowledge Tutorial System, an LMS platform offering a variety of online educational and training options to petroleum engineers and geologists, is presented. It was created using Moodle, open- source software that can be used to create on-line courses. The platform covers fundamental educational concepts in a structured way. It follows an optimized ＂workflow＂ that can be applied not only to solve a specific exercise but also any similar problem encountered over the course of one＇s career. The platform was designed to offer a repository of learning material in various forms and to favor user-platform interactions. It can be used for training and evaluation purposes through exercises and problem solving that the user can perform online by using browsing software along with internet access. Special tools were created and implemented on the platform to assist the user in completing a variety of tasks including performing exercises involving calculations with given data and plots of points or lines on graphs without leaving the learning environment. Furthermore, videos with detailed explanations follow each learning module and provide the full solution to every exercise. The LMS automatically keeps a large statistical database including the users＇ access to activities on the platform that can be exported and further processed to improve the platform functionality and evaluate the users＇ performance.展开更多

PXI is being selected as the platform of choice for thousands of applications, from areas such as military and aerospace, consumer electronics, and communications, to process control and industrial automation. One of the key elements driving the rapid adoption of PXI is its use of PCI in the communication backplane. Now, as the commercial PC industry drastically improves the available bus bandwidth by evolving PCI to PCI Express, PXI has the ability to meet even more application needs by integrating PCI Express into the PXI standard.展开更多

This online tutorial was created to increase public health professionals’ knowledge about breastfeeding and to assess their attitudes in supporting healthy behaviors related to infant feeding as a health promotion strategy. Method: The study utilized an online breastfeeding tutorial based on the US Breast-feeding Committee recommendations for minimum breastfeeding knowledge for health professionals. Pre- and post-tutorial questionnaires assessed breastfeeding knowledge, and an attitudinal survey evaluated attitudes of public health professionals after the tutorial. Exposing public health students to this information can facilitate the early shaping of their attitudes and understanding about the importance of breastfeeding. Results: Fifty-two Northeastern University MPH students and alumni (62% response rate) completed the study. There was an overall gain in participants’ fundamental knowledge regarding breastfeeding as assessed by pre- (77%) to post-tutorial (97%) correct responses (p = 0.00001). The post-tutorial attitudinal survey showed that 92% of participants were comfortable in answering questions about breastfeeding as part of their professional responsibilities. Conclusion: This pilot study highlights the important role that a short online tutorial can play in expanding public health professionals’ knowledge about breastfeeding. Greater use of online methods can enhance awareness of critical health behaviors, such as breastfeeding, that have not received adequate attention in public health curricula. This pilot study provides the foundation for a larger study. Integration of breastfeeding into public health professionals’ core training could support broader social change.展开更多

An empirical study is carried out to compare the teachers’ knowledge level of 91 normal students under three different educational probation modes: tutorial system, non-tutorial system, and routine system. Quantitative analysis shows that except English knowledge, the tutorial system is more conducive to promoting normal students’ mastery of educational theory knowledge, general curriculum knowledge, English curriculum knowledge, English teaching knowledge, and students’ knowledge, and the development of these kinds of knowledge is relatively balanced. This study is helpful for teacher educators to provide guidance and help for pre-service English teachers to maximize the benefits of educational probation.展开更多

However, problems of varieties have also occurred along its way. People never stop thinking of better strategies either in designing online course wares or tutorials to help smooth the learning process. My experience as a tutor is that interaction of affective domain and higher levels of cognitive domain of Bloom＇s Taxonomy plays an important role in face-to-face tutorials of online English learning.展开更多

This article is intended for beginners who are interested in programming their own network visualizations, or for those curious about some of the basic mechanics of graph visualization. Four easy-to-program network layout techniques are discussed, with details given for implementing each one： force-directed node-link diagrams, arc diagrams, adjacency matrices, and circular layouts.
