Description

This paper describes the development of an instructional material for binary number operations in a dynamic web format to be used in fundamental computer theory. Most traditional web materials mainly showed operational problems in static screen displays. They lacked relevance to actual problems for materials that did make use of moving images and animation. Recently, a lot of the materials appear to be creatively devised, animation was adopted in illustrating solutions and explanations. Since the animations used in these materials were presented after learners have given their solutions, they are not designed to lead learners to understanding the problems. This study reports about the system of an instructional material in Dynamic Web format in order to overcome this dilemma. As the main feature of this system, the radix conversion, addition, subtraction, product, and the quotient of binary numbers were made within scope of the problems Dynamic Web pages have been provided showing, step by step provided, the processes leading to the solution and the processes showing errors for the detailed batch of answers in animation.The system has been used and tested in university lectures and the paper discusses the result of a survey conducted among students, which includes their impressions after using the system and comparisons with traditional teaching methods, as well as its effectiveness and fixed learning effect.
