Which approach best supports science literacy and argumentation for diverse learners?

• A. Rely on memorization of terms
• B. Use lectures with no hands-on exploration
• C. Provide accessible explanations, use evidence-based claims, scaffold notes and vocabulary, and connect to students’ cultural experiences
• D. Avoid vocabulary supports and visuals

Answer: (C)

To support science literacy and argumentation, students need explanations that are accessible to all learners, a practice of making claims with evidence, scaffolding for notes and vocabulary, and meaningful connections to students’ cultural experiences. Accessible explanations help diverse learners understand core ideas without getting stuck on language barriers, while using evidence-based claims models how scientific reasoning works—students learn to justify conclusions with data, observations, or experiments. Scaffolding notes and vocabulary provides the language and supports students need to follow, discuss, and construct arguments, gradually building their independent reasoning. Tying science to students’ cultural experiences validates their funds of knowledge, increases engagement, and gives authentic contexts for using evidence to support ideas, which is crucial for developing confident scientific argumentation.

Memorization focuses on recall rather than understanding or reasoning. Lectures without hands-on exploration limit opportunities to investigate, test ideas, and practice arguing with evidence. Skipping vocabulary supports and visuals makes concepts harder to access and makes it tougher for students to articulate their reasoning.
