State mo muna as an introduction yung dilemma ng parents and ng students (kayo) na somehow, hindi ready sa mas pinatagal na educ. system. State ka ng reasons and yung comments ng ibang tao (do a research or magimbento). Then dun mo na ipapasok yung "...but in the light of all those arguments we have chosen not to look at...", ipasok mo na yung advantage nya. Then sa closing, summarize mo lahat ng sinabi mo leading to an end na dapat mapush or mamotivate yung audience na "Ay, oo. Maganda nga ang K-12 blablabla". It's all up to you.

Future teacher here, by the way.
