Nine ways to Reduce CL in Multimedia Learning

Working memory capacity is limited and consists of multiple processors (Baddely). According to the modality effect, learning in a multimedia environment will reduce the learners’ cognitive load by means of presenting information in visual mode and auditory mode. Therefore, the lecture in a multimedia environment could increase learning.

Students who are low performance in mathematics might be low-spatial abilities and low self-regulation. Therefore, it is also necessary to consider how compensate for learners’ low level of spatial abilities and what kind of strategies are appropriate, because multimedia instructional messages are more efficient for high-spatial ability than for low-spatial ability (Mayer, R.E. 1994).

When explaining mathematics concepts or problems assigned, some terminologies and symbols are used frequently. It results in effective process a narrated animation to make sure of the terminologies meaning and what symbols represent before the explanation. This result is called a pretraining effect.

For example, "HINT" button could be work well. It gives learners two effects; reducing overloaded and avoiding redundancy for learners as the learning progressing occurs expertise reversal. In addition, it provides learners learner-controlled opportunities. Therefore students could adjust the environment for their preferences.
