Which of the following tasks would be least effective in teaching phonological awareness?

The task of writing a report is least effective in teaching phonological awareness because this skill primarily involves the ability to recognize and manipulate sounds in spoken language. Phonological awareness includes skills such as identifying, segmenting, blending, and manipulating sounds at various levels, such as syllables and phonemes.

Reading nursery rhymes aloud, singing songs with phoneme replacement, and practicing blended phonemes are all activities aimed specifically at developing a child's awareness of sounds in language. Nursery rhymes expose listeners to rhythm, rhyme, and sound patterns, which are crucial for building phonological skills. Singing songs with phoneme replacement encourages children to play with sounds, helping them understand how phonemes can be altered to create new words. Practicing blended phonemes directly involves the manipulation of sounds, reinforcing the ability to blend individual phonemes into words.

In contrast, writing a report typically focuses on written language and composition skills rather than the auditory aspects of phonological awareness. While writing is an important part of literacy development, it does not inherently engage with the sound structures of language that are essential for phonological awareness.
