Intelligent Approach

Formal learning has shifted from the confines of institutional walls to our home computers and even to our mobiles. It is often felt that the concept of e-learning can be successfully applied to theoretical subjects but when it comes to teaching of science subjects like chemistry where hands on practical training is must, it is inadequate. This chapter presents a hybrid approach (amalgamation of concepts of machine learning technique with soft computing paradigm) to develop an intelligent virtual chemistry laboratory (IVCL) tool for simulating chemical experiments online. Tool presents an easy to use web based interface, which takes as input the reactants and presents results in the form of - type of reaction occurred and the list of possible products. Technically, the IVCL tool utilizes naïve bayes algorithm to classify the type of reactions and then applies genetic algorithm inspired approach to generate the products. Subsequently it employs system of equations method to balance the reactions. Experimental evaluations reveal that proposed IVCL tool runs with 95% accuracy.

Web Based System

The new technology era is shifting the traditional ways of seeking knowledge and plays a new role in disseminating and sharing knowledge. E-learning systems have been introduced with the emergence of and developments in information technology (IT). However, most e-learning systems focus on allowing students to access and use official educational content, with less attention being paid to involve e-resources linked to curricula to support the educational process and the learners. The main objective of this research is to empower users in an e-learning environment with an Information Communication Technology (ICT) web-based system in order to play a bigger role in seeking and sharing e-resources for a better understanding of the curricula. The article focuses on the problem of teaching students in e-learning. The results of a survey helped us identify the main difficulties facing students when they begin their studies. We also describe a methodology of teaching using e-learning as web-based instruction. The use of e-learning in the educational process improves the quality of practical training and provides a better understanding of the course. This study proposes a web-based system that integrates elements of e-resources within an e-learning environment by using e-classes of 7th, 8th, and 9th grades enrolled at Secondary School as a testbed. The system deals with a set of learning cycles that support the aims of e-learning. The first cycle is the student; the second cycle is the teacher. In this study, quantitative and qualitative approaches have been used to evaluate, investigate, and compare the system's impact. The results of this study revealed that there is a significant difference between the students according to grade. Therefore, students at Secondary School would benefit from a system that exposes them to e-resources linked directly to the curriculum to achieve and navigate knowledge understanding.

With the rapid increase in the volume of e-commerce, the security of web-based transactions is of increasing concern. A widespread but dangerously incorrect belief among web users is that all security issues are taken care of when a website uses HTTPS (secure HTTP). While HTTPS does provide security, websites are often developed and deployed in ways that make them and their users vulnerable to hackers. In this article we explore some of these vulnerabilities. We first introduce the key ideas and then provide several experiential learning exercises so that readers can understand the challenges and possible solutions to them in a hands-on manner.
