The McGurk effect proves that audio and visual are always involved and interrelated. It's important to remember this fact, and when we use multimedia in our classrooms, we have to know that visual image influences what we hear, even when the input of the two aspects are the same. We need to be careful not to let the multimedia become an overburden to our students' cognition. Students' attention can be led by the direction of the teacher. So, it's crucial that the teacher use multimedia in a proper way that helps rather than hinders students' learning. Therefore, teachers first need to identify the goals of their lessons. Bloom's taxonomy, dividing learning objectives into six levels considering their complexity and specificity, helps teachers to set the objectives for their lessons. When the objectives of the lesson are clear, teachers then need to evaluate the software they'll be using to conduct the lesson, whether it enhances or overburdens students' learning. Visual and audio input should not be in contrast with each other, they need to support each other.
