Abstract Introduction: Deaf and hard-of-hearing (DHH) students experience persistent difficulties in science education due to language and communication barriers, emphasizing the need for effective visual and multimodal instructional approaches. This study investigated the effects of graphic organizer-supported instruction on the scientific process skills (SPS) of DHH students.

Introduction Hearing loss needs to be diagnosed early, and intervention should begin promptly (CDC, 2024). More than 5% of the world’s population, equivalent to 430 million people, requires rehabilitation to address hearing loss (including 34 million children).

When necessary precautions are not taken, hearing loss can lead to more serious problems.
