RELATION TO PRIOR KNOWLEDGE OF PUPILS

Two experiments are discussed in which the sequencing procedure of webteaching is compared with a linear sequence for the presentation of text material. In the first experiment variations in the level of prior knowledge of pupils were studied for their influence on the sequencing mode of text presentation. Prior knowledge greatly reduced the effect of the size of sequencing procedures. In the second experiment pupils with a low level of prior knowledge studied a text, following either a websequence or a linear sequence. Webteaching was superior to linear teaching on a number of dependent variables. It is concluded that webteaching is an effective sequencing procedure in those cases where substantial new learning is required.
