Procedural tasks are step-by-step activities completed much the same way each time. These benefit from demonstrations followed by hands-on practice with feedback.
Principle-based tasks are governed by guidelines that are implemented differently each time. Here participants need to see demonstrations showing how the task is carried out in a variety of situations and then practise the task in diverse situations. These tasks are especially amenable to group settings.
A process is a series of stages that operate in sequence on a cause-and-effect basis. Examples of processes include the workings of a computer, the way learning occurs in the brain, or the stages in performance management. You can help people to understand a process using diagrams, experiments, case studies and simulations.
Facts are arbitrary pieces of information that need to be memorised or referred to as needed. It is not easy to remember facts, so nothing beats repeated practice.
A concept is a word or phrase that represents a whole class of items that share common features. ‘Word-processing’ is a concept, whereas the product ‘Microsoft Word’ is a fact; ‘actor’ is a concept, whereas the name ‘Harrison Ford’ is a fact. To teach concepts you need to explain the unique characteristics of the concept, provide lots of examples and then have participants identify correct and incorrect examples.
