Merrill's 5-Star Model also known as The First Principles of Instruction , assumes design principles apply regardless of the instructional program or practice prescribed by a given theory or model (Merrill, 2001). Based on Chickering and Gamson’s (1987) Seven Principles for Good Practice, this research project attempted to revitalize the principles by merging them with Merrill’s (2006) Different Levels of Instructional Strategy.

Yet, much Enter your email address to receive notifications of new posts by email. Merrill’s view is that presenting large amounts of information and expecting learners to be able to both process and understand it is unlikely to be effective as their ability to understand it, remember it and apply it is limited by factors such as varying attention spans, the limitations of working memory, variations in prior knowledge, and incorrect, incomplete or even non-existent mental models. Activation Learning is facilitated when learners can reflect-on, discuss, and defend how much empirical evidence supports First Principles? Association for Educational Communications and Technology.

There is no guarantee that any specific fund or investment strategy will meet its investment objectives. The key difference is that a problem-centred approach first teaches learners all of the knowledge and skills needed to solve the problem or make a case decision whereas problem and case-based learning events often require the learners to acquire some of the necessary knowledge and skills whilst they are actually engaged in problem-solving or case-based learning.
