The Marungko Approach was developed by Nooraihan Ali and Josefina Urbano to improve reading skills and teacher competence in teaching reading, especially in Grade 1. It uses a "phono-syllabic" method, teaching individual sounds and blending them into syllables and words. The approach starts with letter sounds rather than names, and introduces letters in the order of m, s, a, i, o rather than the alphabet. It teaches sounds individually, has students write the letters as they make the sounds, and then blends sounds into words, phrases, and sentences once mastery is achieved. Additional words and letter sounds are gradually introduced in relation to those already learned.
