In a lesson focusing on the diphthong /oi/, which of the following materials would NOT be useful?

In a lesson focusing on the diphthong /oi/, the choice of using leveled readers for context practice may not be as beneficial as other materials available. Although leveled readers provide a context for reading, they primarily focus on larger text comprehension and may not specifically highlight the /oi/ sound effectively. This can lead to a lack of targeted practice with the diphthong itself.

In contrast, using flashcards of the diphthong directly addresses phonemic awareness, allowing students to visualize and hear the sound clearly. Phoneme charts for articulation can help students understand how to produce the /oi/ sound correctly, reinforcing proper tongue and lip placement. Worksheets with phoneme matching can offer practice in identifying and differentiating the diphthong within various contexts, promoting mastery of the sound in isolation and within words. Each of these alternative materials facilitates focused practice on the diphthong, aligning more closely with the goal of the lesson.
