These stages are based on long-term memory, declarative memory, and procedural memory. When a learner receives instruction and information about particular skills, the instruction will be encoded as a set of facts about skills. These set of facts will be interpreted further to generate desirable behaviour. The declarative stage is a cognitive stage in which processing of information is deliberate, slow, and requires complete attention. The procedural stage involves performing skill and the generation of particular behaviours that reflect knowledge from a declarative stage. In this study, the students’ ability to handle scientific apparatus will be manifested in the procedural stage. During this stage, students should have the ability to apply certain skills, such as using a thermometer, appropriately based on the theoretical knowledge of using a thermometer constructed in the earlier stage.
