Abstract


Algorithm is an important element in mathematic and the corresponding application, a significant basis for computing science. In modern society, computers have become indispensable tools for people’s daily life and work, and algorithm is what computers depend on to address puzzles. Consequently, algorithm thought should be a math literacy needed by modern people. So far, many developed countries have brought algorithm into middle schools. In 2003, senior high school curriculum standards were published in our country; among them, mathematic standard requires that algorithm be a compulsive part in mathematic curriculum while IT standard demand "Algorithm and Program Design" be an elective part. However, as algorithm is puzzled, it has always been a difficult point in computer science teaching, and traditional static teaching method, consisting of chalks and textbooks, is not able to help students actually understand algorithm thought.As a visual tool, Algorithm Animation is able to clearly, dynamically and interactively show how a algorithm runs by graphs, which provides new opportunities for multimedia teaching. Since Ronald M. Baecker developed a video called "Sorting Out Sorting" in 1981, a series of Algorithm Animation have been developed and relevant papers have been published. As a result, all over the word people begin to study Algorithm Animation and its application in teaching, and certain achievements were made in computers teaching area.In the paper, the author makes a survey about how well algorithm teaching is going in senior high school in our country, analyses the existing problems. And after plenty of literature consulting, she gives a systematic introduction on Algorithm Animation and its application in computer science teaching. Besides, in light of theories of Edgar Dale’s cone of experience, cognition load and instructional design. She demonstrates the feasibility and advantages of Algorithm Animation application in developing senior high school students’ algorithm thought and problems solving abilities.Another emphasis in this paper is how to efficiently apply Algorithm Animation to algorithm teaching for senior high school students, who are beginners about algorithm learning. In other words, the emphasis is algorithm-based instructional design for senior high school algorithm teaching. In addressing this problem, on one hand, after analyzing relevant materials at home and abroad, the author uses existing experience about Algorithm Animation design and its application to teaching for reference, and tries designing an Algorithm Animation system that is directed at senior high school algorithm teaching and based on characters of learners and features of algorithm. On the other hand, in terms of theories of pedagogy, psychology and instructional design and basing on the existing achievements about instructional design, the author probes into instructional design about course of Algorithm and Program design with frontline teachers, whose assistant software is Algorithm Animation, and gives a teaching case for acting as a model. In the end of this paper, the author gives a summary of the research, points out its innovative points and shortcomings. Besides, she briefly states what to do in future concerning this research and paper.Luckily, through interviews and observations of the practical application to classrooms, it is proved that the Algorithm Animation system developed and the teaching scheme designed in this paper are able to effectively stimulate learning interests and enhance teaching performance. However, owning to limitations of times and funds, there is not systematic and long-term empirical argumentation about the teaching effect. Teaching experiment is a long-term, circulative process that needs continual demonstration and improvement, and this is what the author will striving to in future.
