This book illustrates an "Easy", "Enjoyable", "Effective" e-Learning system called "Apty" (Automated Practice & Test System). Today, the Internet is just as available in homes as it is in companies, schools and anywhere else where broad-band communication lines are available. This establishes the social environments for e-Learning. However, under present circumstances, e-Learning systems cannot be used without conditions. The spread of e-Learning in elementary schools, junior high schools, senior high schools, colleges and universities is not wide enough. There are a number of issues with current e-learning systems: there are difficulties in installing and administering e-Learning systems; the development of courseware is time-consuming; educators are often forced to use ready-made products; student-users need to perform several operations to reach their desired page of interest because of the complexity of current e-Learning systems; and finally, quality e-Learning systems are costly. This book is divided into three parts: Introduction, Advanced, and Expert. The introduction part explains the general functions of the Apty system. Although the Advanced and Expert parts may require background information in certain cases, nearly all functions of the Apty system can be utilised according to the instructions outlined in this book. The Apty system is "enjoyable". Students can enjoy studying with the Apty system. The system randomly chooses questions from the pool of those previously created and stored. Each time students log in, they can practice a few new questions in a short time. In practice drills and examinations that consist of a series of short quizzes, those top ten scores appear in a subject home page, and anyone can view these scores without logging in. Since the top ten practice scores can be summarised for each week or even for each day, it is possible for anyone to get the top score. The order of the top ten scores changes very often. This can encourage students to study hard by competing with each other.
