The application of algebraic methods to simplify the more complex type of static data structure through visualization approach

Abstract

This paper had the result of action research (AR) of Data Structure course. This paper discussed the elaboration of hight level complexity of composit type of data structure applying algebraic method through visualization approach (VA). The purpose of this research was to simplify the students understanding at any levels of complexity of static type of data structures through the application of algebraic methods with visualization approach. The roles of the applications were the elaboration of any level of type complexity of data structures logically and systematically at to identify each of their individual access. The method applied to this AR was an algebraic method through visualization approach of composite type of data structures in two cycles. The first cycle applied manually visualization approach, and the second applied simple MS-Powerpoint animation of visualization approach. Some examples of third complexity level of composite type of data structures were presented to demonstrate the methods. The results showed that, before the method is applied, none of the 43 students participating in the course of data structures that can be logically and systematically identifies each individual access from any type of data structure composites tested. How ever, after the second cycle levels of AR applying VM shown that the average score of learning outcome was 78.00 and classical mastery learning achievement was 76.74%. It meant that the students achievement were very hight. The conclusion was the application of VM significanly improved data structure programmer competency.
