Final answer:
The best instructional method to enhance a student's understanding of print conventions is to use a finger to track letters and words during shared reading, providing a hands-on, immediate way to learn left-to-right text progression.
Step-by-step explanation:
Based on the assessment data for a student's understanding of concepts of print, the instructional method that will best promote the student's grasp of print conventions is C. Using a finger to draw attention to letters and words in the text during a shared reading. This technique is practical and hands-on, helping to guide the student's visual tracking and reinforcing the directionality of text (left-to-right, top-to-bottom), which is essential for learning how to identify where to read after a given word. This practice aligns with formative assessments used to review comprehension and apply concepts in various learning materials.
Moreover, this method can be part of a set of practice problems and instructional strategies, such as check your understanding exercises or performance tasks, which challenge students to apply their knowledge in practical and relevant ways. It also facilitates a differentiated learning approach that meets this specific student's needs, providing immediate feedback and support, key components for effective literacy instruction in the classroom.
