Circular Iterative Model to develop Computer Based Tutorial (CBT)

A software development life cycle model is a characterization of various steps involved in the development of a software product. These phases in a software model range from planning to implementation and maintenance of the software. There are many existing software development life cycle models which are applicable for developing various types of software products. Despite the existence of many models, there are many complex projects that cannot be successfully developed using the same. With the emerging trends in computer technology and use of computers in various fields, there has been advancement and growth in the field of education as well. Computer-based tutorial and other e-learning software's are quite popular these days, thus giving the privilege of easy and flexi-learning. A Computer-based tutorial is basically an interactive software program which is created as a learning tool. Tutorials help people learn new skills in a step by step process and hence ensure that the user is following the same. A computer-based tutorial has become really popular and the process of its development is becoming a necessity today. Developing a computer-based tutorial may seem a very simple and easy going task but with due research in the same field reveals that many uncertainties arise during the development of an e-learning tutorial. Hence there is a need for a flexible yet understandable model, which can be implemented in order to develop computer-based tutorial software. As, there is need for a model, a sequence of steps which constitute a circular model can be implemented for a project like e-tutorial. The steps in the circular sequence may keep iterating so that timely updating may be made to the software accordingly. The circular iterative model can prove to be beneficial for developing all types of e-tutorial softwares.
