            (9) Multimedia Principle

              People learn better from words and pictures than from words alone.

           (10)  Personalization Principle

              People learn better from multimedia lessons when words are in conversational
            style rather than formal style.
           (11)  Voice Principle

              People learn better when the narration in multimedia lessons is spoken in a
            friendly human voice rather than a machine voice.

           (12)  Image Principle

              People do not necessarily learn better from a multimedia lesson when the
            speaker’s image is added to the screen.
              These twelve principles can divide into three groups based on the types of
            cognitive load, as shown in Table 8.2.


            8.2.4.2 Case Study
            For learning design of Newton’s first law, as the content is difficult and abstract, we
            have to use some multimedia resources.
              Design strategy:
            (1) Use flash or animation experiment presentation.
            (2) Use daily life examples and pictures.
