PLEASE SHARE  some INFORMATION about 5E

In 1962, science educators J. Myron (Mike) Atkin and Robert Karplus argued influentially that effective learning cycles involved three key components: exploration, term introduction, and concept application . In their scheme, exploration allowed the learners to become interested in the subject at hand, raise questions, and identify points of dissatisfaction with their current understanding. Introduction of new ideas and terms, primarily by the instructor, but negotiated by both instructor and students, followed. Finally, concept application provided learners with opportunities within the classroom to apply their new ideas, try out their new understandings in novel contexts, and evaluate the completeness of their understanding.

Bybee and his BSCS colleagues described the 5E model as a “direct descendant of the Atkin and Karplus learning cycle” and suggested the following expanded sequence of key elements of an effective lesson:

1. Engagement

2. Exploration

3. Explanation

4. Elaboration

5. Evaluation                            The 5E model team reasoned that to have significant impact on classroom instruction, a model would need to have a more tool-like quality than most scholarly models did at the time. The 5E model is based on both a conceptual change model of learning and a constructivist view of learning.  The information about 5E was taken from  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2931660/
