Final answer:
The instructional approaches that support students learning to decode multisyllabic words include explicitly teaching students to isolate base elements and affixes, teaching written syllable types in a logical sequence, and teaching written syllable division patterns.
Step-by-step explanation:
The instructional approaches that support students learning to decode multisyllabic words include:
- Explicitly teaching students to isolate base elements and affixes. For example, teaching students that the word 'unhappiness' consists of the base 'happy' and the prefix 'un-', which helps them to decode the word.
- Explicitly teaching written syllable types in a logical sequence. For instance, teaching students that the word 'robot' follows the closed syllable type, where a vowel is followed by a consonant and is closed off. This understanding helps them decode other similar words.
- Explicitly teaching written syllable division patterns. Students are taught to recognize and divide multisyllabic words into syllables using patterns, such as dividing 'dinosaur' into 'di' and 'nosaur'.
