Let's first take a look at the nine steps as it relates to instruction according to Khadjooi, et al (2011).
1. Gain attention
2. Inform learner of objective
3. Stimulate recall of prior information
4. Present information
5. Provide guidance
6. Elicit performance
7. Provide feedback
8. Assess performance
9. Enhance retention and transfer
These steps are very similar to the framework of Bloom's Taxonomy and every educator has heard the term. When designing instruction, it is important to consider how technology best promotes learning according to Spector. Gagne's theory supports the objectives from a behaviorist perception in that to meet the needs of learners, there should be a combination of behavioral and cognitive theories with the addition of technology as a tool to increase learning.
One main strength of Gagne's theory is the means in which human learning and performance are increased based on prior knowledge and learning styles. Teachers and learners are challenged to creatively design new competencies due to learned behaviors. Gagne's theory can be applied to K-12, and adult learners. For the preschool population, there is some modification required. I would apply this model through lesson planning, practice activities in order that an impact for learners is effective and motivated.
