Abstract— With advancement of computers and Internet, there has been an increasing trend in utilizing computers and Internet for teaching and Education. Advanced topics and High Tech experiments demand for lot of infrastructure. There are areas in living sciences and other subjects where the magnitude of information is so huge that it is more convenient to do the experiment by simulation using computers. The present work relates to development of computer based learning resource that can be used as an online teaching aid or an offline tool to study the Brownian motion in two dimensions. It is an interactive tool where the learner can change the parameters of interest to study the Brownian motion and actually see the effect by way of simulated graphics. Quantitative values of the parameters arising from the simulation study are also available to the learner. The Brownian motion is a phenomenon occurring at microscopic scale and thus actual study of the experiment requires real time monitoring of microscopic development and progress of the Brownian motion which is a tedious task and very difficult to implement in laboratory. To this effect, to carry out the experiment under different desired conditions, a computer based tool is developed that enables the learner to conduct experiment using simulation and see the results quantitatively. It is being uploaded on internet as an online e-learning material.
platform dependence, the cost of mailing materials, and identifying interested users. Instead of searching for people who would like to use a given CBT model, the Web allows the reader to find the material and review it at his own pace. Because Web pages can be updated at any point, it is possible to keep the CBT materials up to date without having to do anything except edit the HTML documents involved. It is also possible to keep channels of communication open between author and reader, even if the two have never met before or had any sort of contact. Finally, the use of server-side scripts and interactive forms make it possible for the reader to be tested on what he has learned without any need for supervision. Computer-based training (CBT) services are useful where a student learns by executing special training programs on a computer relating to their occupation. CBT is especially effective for training people to use computer applications because the CBT program can be integrated with the applications so that students can practice using the application as they learn. BROWNIAN MOTION
Keywords-Computer Simulation; CBT; Brownian Motion
The Brownian motion has been named in the honor of the Scottish botanist Robert Brown. He has presented the theory of Random movement of particles. The Brownian motion is the random movement of particles discovered by the Scottish botanist Robert Brown has made microscopically observations in the months of June, July and August, 1827, on the particles contained in the pollen of plants; and on the general existence of active molecules in organic and inorganic bodies, which can be found in the miscellaneous botanical works of Robert Brown, Volume 1. In his experiment he found that “the pollen particles appeared to move in a completely random fashion”.
INTRODUCTION The world is witnessing a change in every aspect of life since last 2 decades. The advance in Information Technology has opened up new vistas in the history of education also. Computer has become a useful teaching aid. It has infact became an integral part of learning E-LEARNING AND CBT The term E-Learning means electronic Learning and it is basically the online delivery of information, Communication, training and learning. E-Learning seems to have a multiplicity of definitions to each of its users and the term seems to mean something different. A very comprehensive definition has been given by the Cisco System, which defines ‘E-Learning is Internet-enabled learning. Components can include content delivery in multiple formats, management of the learning experience, and a networked community of learners, content developers and experts. E-Learning provides faster learning at reduced costs, increased access to learning, and clear accountability for all participants in the learning process.
The major contribution to the explanation, interpretation and application came from Albert Einstien in 1905and Marian Smoluchowski obtained that “If Kinetic theory of molecules was right, then the molecules in the water would move at random, the small particles to move in exactly the same way described by Brown.” This work of Einstien was further refined by Norbart Weiner a mathematician at MIT, in 1923, established the modern mathematical framework of Brownian motion. OUTLINE OF ACTUAL WORK
The World Wide Web now offers the possibility of conducting CBT on a global scale, without the usual restrictions of
The principles and logic of the Brownian motion is be derived from standard literature such as books and research journals.
