The Design And The Implementation Of Teleeducation Platform--"Power" LTEA System

Teleeducation has spread through all the universities of the whole country, and it has become a branch of the higher learning institutions education. Students in the strange land can listen to and watch relevant teaching course through some communication means of the Teleeducation, purpose to achieve study. But the present Teleeducation development situation can only train students in the way of spreading in one direction, and it can't response students' states of learning and can't test students' results of learning in time. Furthermore, the teachers and the students can't communicate each other promptly, thus hindered the further development of distance learning.Regardless of traditional education or the modern education including Teleeducation, it is the most important links in education to study, test and appraise. Assess and test and have an examination play a very important role in education. How to find out about students' results of learning, how to grasp student's true operative skill, how to weigh students' level reached under education and training ,is it realized through one assessment and test or examination way to need. Have an examination in the past, students use paper basically, teacher set theme, decide one, tedious and very apt to produce the mistake. Some operate type examinations, students answer the questions in a test paper inconvenient and losing contact with reality also, so it causes a lot of examinations to judge by accident resulting in grading unjustly, can't reflect students' true level objectively. Computer assesses and test is that it uses computer to replace traditional paper examination mode to have an examination, so it has just, safe, high-efficient characteristics. Utilize network environment is it set theme group roll automatically to offer, humanized question sheet, full-automatic examination platform of marking examination papers lightening every working intensity of examination links greatly. Improved the objectivity , fairness and security of the examination greatly, dispelled both region difference and space-time difference at the same time , it accords to the nowadays open development model of education, and it is one of the most potential field of modern education.The progress of science and technology makes the society accelerate the change of demand for talent. This kind of change has promoted the reform of education. The proposition of quality-oriented education makes the concept and mode of assessing and testing and examination present new development. With the pluralism of educational form and content, assessing and testing and having an examination present diversified forms correspondingly. Different professional or different field need different examination mode and even the same specialty and the same course need different examination type and examination way too, which has offered wide development space for computer examination. With the development of information technology, the popularization of computer network and intellectual technology of calculation are becoming riper, furthermore, all kinds of examinations will adapt to this kind of change too. Achieving a kind of examination platform intelligently based on network multi-functional will become first-selected targets and development trends in all kinds of examinations in the future. Combining perfect network application with the traditional test and training mode, advanced software engineering, but that becomes that Adopting reeducation platform constructed by latest .net Framework 1.1, professional large-scale database MS SQL Server 2000, XML technology of American Microsoft corp., We have realized a professional teleeducation way based on web way. The whole platform is divided into three sub platforms of students LTEA platform, system management platform and teaching management platform. The teleeducation platform is a LTEA software platform under the environment of the network, suitable for activity of studying on the net , training , testing , exchanging and materials inquiring through In...
