Which instructional approach shows a moderate effect on word analysis skills but a low-to-moderate effect on reading comprehension scores?

• A. Phonics
• B. Phonemic awareness
• C. Phonics taught intensively and systematically to kindergartners and first graders
• D. Whole language

Answer: (C)

Systematic, explicit phonics instruction delivered early strengthens the ability to analyze and decode individual words, producing a moderate improvement in word analysis skills. However, decoding is just one piece of reading; comprehension depends on a broader set of skills like vocabulary, background knowledge, syntax, and strategic reading. When phonics is taught intensively and systematically to kindergartners and first graders, the focus is squarely on letter-sound relationships and blending, which directly targets word analysis and yields that moderate decoding gain. But without integrating strong comprehension strategies and content knowledge, gains in reading comprehension tend to be low-to-moderate. Other approaches—general phonics without explicit structure, phonemic awareness alone, or whole language—don’t consistently show the same robust pattern of decoding benefits with only modest comprehension improvements, so the described approach best fits the tested pattern.
