Final answer:
Teachers should choose keywords for sound-spelling cards that do not contain nasalization affecting vowel sounds, multiple meanings, consonant blends, or phonemes resembling letter names to ensure clarity in teaching phonics.
Step-by-step explanation:
Guidelines for Choosing Keywords for Sound-Spelling Cards
When selecting keywords for sound-spelling cards, teachers should follow specific guidelines to ensure that the words chosen are effective for teaching phonics and sound-spelling relationships. These guidelines include:
- Avoiding words where nasalization affects vowel pronunciation. For example, 'angry' is not ideal for representing the sound /ă/ because the following nasal consonant 'n' can alter the vowel sound.
- Choosing words that have consistent pronunciation and do not possess multiple meanings, which can confuse the learning process. For instance, 'pen' or 'run' may be avoided since they have different meanings.
- Excluding words in which a consonant appears as a part of a blend, which can complicate the isolated sound. 'Stop' for /s/ would not be advisable since the 't' is blended with the 's'.
- Steering clear of words with phonemes that mimic letter names, such as 'empty' (m - t), to prevent confusion between letter names and sounds.
