Q2. Write eight advantages and disadvantages of multimedia in secondary school chemistry experiments?
Answers
Explanation:
Advantages of multimedia:
Students who learned from materials containing both text and graphics produced 55 percent to 121 percent more accurate solutions to problems, according to David Taylor at the University of Maryland. The use of images, along with words, diminishes the overwhelming nature of text and helps the student to manage the cognitive load, which increases retention. Specifically, graphics are found to support retention because important elements are focused on via placement, layout and color. Activation of prior knowledge is engaged quickly with visual analogy, and mental models are created easily as diagrams can enhance understanding of how a concept works. Additionally, learning is made easier because simulations allow students to visualize real-life situations, and motivation is increased as students are able to see the relevance of skills.
Disadvantages of multimedia:
When designing a multimedia learning experience, the role of the teacher shifts from instructor to facilitator. If a lesson allows students to complete learning at their own pace as they move through stages of learning, classroom management becomes increasingly difficult. This is particularly true if students work in groups to view multimedia sources or share computers. Additionally, students who are not as proficient with technology may have to spend more time learning computer skills to access information than focusing on course materials.
