以多媒體聲光效果輔助，並提供教學者自由操作互動的數位教材，一直是教學數位化 的目標。互動式多媒體教學所能提升的學習效果，也在過去的許多研究中被印證。然而， 功能越強大的數位互動教材，其製作時間和困難度也相對提高。 對一般教案設計者而言，現成的多媒體工具中，有些製作出來後就不易再修改變更， 如Flash、Java 等；有些則缺乏互動自由度，如PowerPoint 投影片。對於多數認真的教學 者來說，若無法依照自己設計的教案來進行課程，並有充分的臨場自由發揮空間，則使用 數位教材的意願將大大降低。

The aim of this article is to present some criteria and indicators of manufacturing teaching materials for the educator, based on the multimedia and interactive perspective. In the passed research had already verified the positive study effect of using interactive multimedia in class. However, in the progress of manufacturing interactive multimedia teaching materials, the strength of material function is relative to the production time and difficulty. Therefore, the more time in production, the better function for the educator to operate in class. As for the designer, the present tool or software to make the multimedia material is not flexible enough to re-modify works many times, for instance, Flash, Java and son on. Some of them are lack of interactive freedom such as Powerpoint. In my observation, most hard working educator like to follow their own design material in class, if they could not easily edit or modify the material and freely control the tool in class, then the wish of using multimedia teaching material is naturally reduced.
