The document discusses a study conducted using the textbook "My Pals Are Here" to target specific words and sounds for students in grades 1-3. It identifies the target words containing the sounds /s/, /z/, /æ/, and /e/ for each grade level. A pre-test and post-test were administered to measure improvement. The results showed an average increase of 5 points from pre-test to post-test, demonstrating that using the textbook helped students learn the target words and sounds.
