Thoughtful Image Selection
By Eun Sandoval-Lee, Assistant Director of Learning and Teaching
Images are more than visual accents—they shape how students experience learning and how instructors communicate their values. Thoughtful image selection can foster belonging, accessibility, and engagement, all of which are central to student success. At the same time, adopting intentional practices around visuals supports instructor vitality by reducing “decision fatigue” (Emetu, 2024) and aligning teaching materials with inclusive teaching principles. This guide offers a practical process (see Figure 1) and reflection areas (see Figure 2) to inspire instructors to make small, meaningful changes in their visual communication that enhance learning environments and strengthen the human connections essential to teaching.

Pinch Point #1: Limited Representation
Images in slides often default to stock photos that mis- or under-represent some groups, unintentionally signaling who “belongs” in the discipline.
- Plus One: While finalizing a slide deck, review any images including people to find any patterns in visible representation, and change one image in a meaningful way. This small act fosters belonging and signals inclusivity.
Pinch Point #2: Accessibility Gaps
Images in a learning management system without alt text or poor color contrast create barriers for students with visual impairments or color vision differences.
- Plus One: Use Pope Tech, available by default in all Canvas courses sites at Northwestern This tool makes pages more usable for all learners.
Pinch Point #3: Uncritical Use of AI-Generated Images
AI tools can perpetuate stereotypes or bias, undermining inclusion.
- Plus One: If/when using AI-generated images, tell your students. This transparency models ethical decision-making and builds digital literacy.
