The Effectiveness of Practical Work In Science
Hence, there is much debate regarding the use of practical work within the teaching and learning of science in schools. The elemental question here really has to do with cognition and how exactly we acquire knowledge.
One answer to this dilemma originated from Jean Piaget, who is credited as the pioneer of the constructivist theory of knowing. He argued that people continuously construct more complicated and advanced representations of the world by modifying existing understandings through our actions. If Piaget is correct, then the use of practical work in observing and participating in the process must be vital for our understanding of science (R Miller, 2004).
Yet, many of the conclusions drawn from research regarding the effectiveness of practical work remain somewhat ambiguous.
