My view on Computer-assisted language learningAbstractComputer-assisted language learning, which makes the most use of modern multimedia technology to create a more lively language teaching environment than the average computer-assisted language teaching, is to further improve the quality of teaching and broaden modern teaching methods and ideas. This system is the combination between computer and multimedia, a strong sense of realism and expressiveness in term of the transmission of information which can arouse students' interest and attention, to promote students to participate actively in the media activities emotionally, impart knowledge, develop intelligence, and cultivate capacity. With the development of multimedia technology, which is based on computer-mediated communication, it will eventually synthesize with communication and playback system, plays a significant role in the future in the information market, and has an enormous impact on humanity learning environment.Multimedia technology plays an important role in all walks of life, also in the field of teaching, the use of multimedia technology, which is conducive to improve the level of teaching. This paper discusses the application of multimedia teaching, the advantages and disadvantages of multimedia technology, and how to use multimedia. Multimedia teaching is based on information dissemination theory and the ways of the teaching process design, implementation, and educational evaluation process. In the traditional teaching methods, the communication between student and teacher is simple, and blunt blackboard and chalk tend to make teaching activities boring. Computer-assisted language learning breaks the traditional teaching model, which makes full use of diverse multimedia audio and video files, to make teaching activities very fascinatingly.It will not only enhance their interest and motivation in learning, but also greatly improve the quality of teaching.Key words：advantages; disadvantages; multimedia; problems;I. Advantages of multimedia teaching are mainly reflected in the following two aspects:1. Computer-assisted language learning is in favor of language interaction. First, CALL makes learners have more time to think, so that they can understand information better and control their own language output. Secondly, CALL provides a stress-free language environment for learners, where learners can decide when to participate, answer questions in no pressure.Finally, CALL establishes an easy and convenient learning community, where learners can share resource, exchange and participate actively in discussion under the guidance of teacher, to make great progress.2. CALL let students interact with the Internet. The Internet is a virtual library which can provide a variety of resources for students; on the other hand, the Internet provides text, image, sound, video and other multimedia information, which stimulates learners' interest in learning, and encourages learners to explore and use the Internet with higher enthusiasm. Therefore, the effective use of Internet resources can create positive interaction between students and Internet.II. How to use Computer-assisted language learning: The key to carry out CALL is teacher; Firstly, Teachers should recognize the importance of CALL. Secondly, teachers should continue to improve their abilities to use CALL. Of course, the most important thing is the teacher's professionalism. We have to love really the students, the real student-centered, never forget to inspire and educate students.To sum up, the teachers are perpetrators of CALL, and the key of educational success.1. Making use of Computer-assisted language learning very appropriately. Computer-assisted language learning is teaching method in the teaching process. The subject of classroom teaching is still student. Therefore, the design and use of CALL are always according to students in the first place. Some teachers use a long, large-capacity courseware, because courseware is too long, in essence, a "teacher-centered" teaching idea evolves into a "computer and teacher-centered" teaching idea. This courseware has several obvious disadvantages: the leading role of teachers in the teaching process is not to reflect, and the initiative and creativity of teachers in the teaching process has been detained. Large-capacity long courseware will consume a lot of time and effort of teachers, which increases the difficulty of CALL, and impacts teachers’enthusiasm to use CALL. It has proved that the effect of large capacity courseware all the time is not ideal. Because it will let students give rise to visual fatigue, and distract students’ attention. Therefore, courseware should be small, fine, and short.2. The CALL design should pay closely attention to teaching materials. Fully grasping the textbook significances, difficulties, finding an entry point for multimedia and teaching content, and reflecting teaching strategies, will provide students with plenty of opportunities to practice. At the same time, it should follow students' thinking patterns and cognitive rules. Some courseware design, which only follows the order of original teaching materials, is with little regard for the teaching content presentation whether it can adapt to the cognitive ways. Therefore, this concept of design courseware can not show prominent feature and advantages of CALL.III. The effects and problems of Computer-assisted languagelearning:Lacking of hardware devices and technologies, our previous network teaching mode is single, only provides teaching video and multimedia courseware for students, and hardly any interaction between teachers and students, which lead to the bad teaching effect. Since we implement a new teaching model, the students' interest and motivation improve significantly, and meet our expectations of teaching.However, in the process of teaching, we also find that, although the effect of teaching model is obvious, the opportunity to encourage students to practice in the learning process is not too much, which is very unfavorable for learning. To solve this problem, we plan to optimize the technical content of online teaching platform, increase the voice and video chat rooms, arrange fixed and non-fixed time to chat, and supply the opportunity to exchange among students.BibliographyAltenburg, B.
