The Design And Development Of Network Courseware For Add And Subtract Operation Instruction

The rapid development of information technology, for people's study, the life brought about profound changes, especially in the network popularization, the application of education teaching, is gradually changing the traditional teaching and learning mode. The network courseware as an Internet technology in education teaching the application by the necessary elements, the more people's attention. It can provide more friendly learning interface, can provide excellent pictures and texts, audio-visual synchronized audio-visual experience, making the abstract concept of intuitive form with image shows in front, be helpful for understanding and learners of memory. And is committed to creating an independent and interactive learning environment.The union university undergraduate stage of computer technology and relevant professional the microcomputer principle and application "course main characteristics. How to let the student in limited time grasp abstract concepts, understand its operation principle, is to independent, the interactive network courseware request. The paper takes the add and subtract operation instruction of the network courseware design as an example, the abstract knowledge specific, direct, and dedicated to the student practice individualized counseling exploration.Courseware for the development of software development ideas and teaching by combining design thought summed courseware design models, and use to actual design. Software development is divided into seven stages, respectively, requirement analysis, system software requirement analysis, general design, detailed design, code, test and operation and maintenance. According to the characteristics and requirements, courseware development into the planning stage will courseware design stage and courseware, courseware implementation and evaluation stages. The planning stage including courseware development environment analysis and use object analysis two aspects. Courseware design stage includes teaching design and courseware structure design two aspects. Courseware implementation of multimedia material production and courseware into editing synthesis. Courseware evaluation phase is divided into designing appraisal gauge and trial test two aspects. This is "add and subtract operation instruction" of web-based courseware design follow mode.Courseware development, the first confirmed the teaching purpose is to let the courseware students to grasp arithmetic operations instruction in addition and subtraction instructions instruction using rules and significance. Can use these two instructions, and understand instructions written instructions after execution of the sign bit changes.With teachers lectures different, the design of courseware adopted knowledge presentation, independent practice and experimental operating three key link. Through the knowledge representation of addition and subtraction, let students understand the operation instructions commands format and the matters needing attention; Through independent practice, students can clearly understand the master degree of knowledge; Through the virtual experiment, achieve consolidated and practice, let students to sign the sign bit understand register more profound. This lesson completed the integrity of knowledge points for the formation of the students' knowledge system lay the foundation. Courseware design focuses on training students through independent practice and simulation experiment, will use and transfer of knowledge to level. Independent practice, courseware preset wrong information feedback present, so that helps students learn later. Simulation experiment present directly each mark a change, make the abstract concept materialize and help students understand and grasp. Through such training, facilitating the learners can will principle knowledge and computer bottom link operation state, breakthrough microcomputer principle learning difficulties.Later, the courseware design by black box testing and integration test method to measure the function of courseware, can run normally.
