Computer animation can be effectively incorporated into computer based instruction programs for English as a Foreign Language (EFL) learning environments. Computer animation is defined as computer-generated animated graphics that function as visual aids to instruction. The applications of instructional graphics fall into two categories: (1) affective functions, which are designed to improve a student's attitude toward learning or to increase the incentive of a student to participate in a lesson, and (2) cognitive functions, which are designed to directly enhance the ability of students to learn from instructional materials. According to design method, computer animation may be classified into fixed-path animation, which is pre-programmed or designed by the software developer, and data-driven animation, which is controlled by the constantly changing data based on user input. The most promising areas of using computer animation for EFL include the teaching and learning of beginning English phonetics, action verbs, and certain cultural elements. Developmental considerations include whether or not to use animation, the choice of programming language or an authoring tool, cultural considerations of target users, operating environment, hardware requirements, and what other resources to use.
