教學媒體在教學上的重要性

The Importance of Educational Media in Teaching

媒體又稱媒介，將事物從一人、一地傳至另一人或另一地，若媒體用於傳遞以教學為目的的信息時，則稱為教學媒體。今日的教育著重學習者的參與和教材的具體化，所以各級教師均被鼓勵多採用教學媒體，以達到完滿的教育目標。但是存在教師心中的疑問乃是：教學媒體真的這麼有效嗎？花時間和精力去設計、製作教學媒體，值得嗎？筆者試從學習理論、教學傳播及教與學的配合來回答這個令人困擾的問題。得到的答案是肯定的，教學媒體對於教學確實是重要的。若沒有教學媒體而想達到學習理論所歸納的諸原則，是相當不容易的；不應用教學媒體要想做好教學傳播可得花很大的力氣；不採用媒體而想教與學有良好的配合，更是緣木求魚。所以媒體的設計、製作與選用，固然疑時費力，卻值得教師們努力，得到的效果更是事半功倍的。

Today, education focuses on the learner's participation and concrete idea of teaching materials. For the sake of perfect objective, teachers of each level are encouraged to adopt teaching media. 'Are teaching media really so effective?' 'Is it worthwhile to spend money, time and effort to design and produce teaching media?' These two questions always bear in teacher's mind. The author-tried to answer these bothersome questions from the viewpoint of learning theories, teaching communication and the coordination between teaching and learning. After document reviewing and inferencing, the writer found the answer is affirmative. Teaching media are very important. Without application of teaching media in classroom, none of learning theory priciples could be fulfilled. It would take a lot of exertion to reach a good teaching communication without application of teaching media. It's impossible to coordinate teaching with learning without using media. Though it spends time and effort to design, produce and select media, the teacher's endeavor is worthy, and half the work with double the result.
