Phonics-based instruction is a method of teaching reading that focuses on the relationship between letters and sounds. It helps learners understand how to decode words by sounding them out, which is essential for reading fluency. This approach often involves teaching the alphabet, letter sounds, and blending techniques to form words. In a phonics-based program, students typically practice with phonetic patterns and word families to build their reading skills. This method is widely used in early childhood education and is considered effective for helping children develop strong foundational skills in literacy.
