How to Use a Screen Marker for Presentations and TeachingA screen marker — whether a physical dry-erase pen used on a glass whiteboard or a digital annotation tool used on a touchscreen or projector — can transform a presentation or lesson from static slides into an interactive, memorable experience. This article explains why screen markers matter, describes different types, and gives practical techniques, lesson-ready workflows, accessibility tips, and troubleshooting advice so you can use screen markers confidently in classrooms, training sessions, and meetings.
Why use a screen marker?
- Engages the audience. Real-time annotations draw attention and let learners follow the thought process.
- Clarifies complex ideas. Emphasizing, circling, and writing formulas or steps helps make abstract material concrete.
- Supports active learning. Asking participants to suggest annotations or to come up and mark the screen increases retention.
- Flexible pacing. You can pause to annotate, summarize, or rearrange ideas without changing slides.
Types of screen markers
-
Physical markers (for glass or whiteboard-style screens)
- Dry-erase markers: common, easy to clean on whiteboards; avoid on plastic projector surfaces unless explicitly allowed.
- Wet-erase markers: less likely to smudge; useful for sessions where marks must remain visible between breaks.
- Liquid chalk markers: bright on dark glass or acrylic; require testing for residue.
-
Digital annotation tools (software-based)
- Built-in OS or device tools: Microsoft Ink on Windows, Apple’s Markup on iPad/macOS, or Android’s native stylus features.
- Presentation software: PowerPoint’s pens/highlighters, Keynote’s annotation mode, Google Slides’ laser pointer and drawing tools.
- Dedicated apps: Zoom, Microsoft Teams, Miro, Jamboard, GoodNotes, Notability, and screen-marker utilities that overlay any app.
- Stylus-enabled tools: Wacom tablets, Apple Pencil, Samsung S Pen provide precision and pressure-sensitive strokes.
-
Hybrid setups
- Interactive flat panels (IFP) combining touch, multi-user annotation, and built-in whiteboard apps.
- Document cameras or mirrored tablet setups that let presenters write on a tablet while projecting to a larger screen.
Preparing to use a screen marker
-
Choose the right tool for your environment
- If participants will interact directly with the screen, use an IFP or touchscreen with a durable surface.
- For remote or mixed audiences, prefer digital annotation tools that stream cleanly over video calls.
-
Test beforehand
- Check compatibility with your device, projector, or conferencing platform.
- Test marker visibility from the back of the room and on camera (remote participants often need higher contrast).
-
Prepare slides for annotation
- Leave blank or lightly designed slides at key points for live writing.
- Use high-contrast backgrounds—light backgrounds with dark ink or dark backgrounds with bright ink.
- Add a “pause” slide (title plus ample white space) where you plan to slow down and annotate.
-
Organize tools and backups
- For physical markers: bring multiple colors, spare pens, and a safe cleaning solution.
- For digital tools: have a backup input device (mouse, second stylus) and ensure battery levels are charged.
Techniques for effective on-screen annotation
-
Use color intentionally
- One color for emphasis, another for contrasting ideas, and a third for corrections or actions. Keep it simple—3 colors max.
-
Layer information
- Start with an outline, then add details in subsequent passes. This sequencing helps learners follow logical progress.
-
Simulate handwriting speed
- Write legibly but deliberately. Slower writing lets learners copy and digest, especially for complex formulas or code.
-
Combine drawing with text
- Use arrows, boxes, and simple icons (check marks, Xs, lightbulbs) to connect ideas quickly.
-
Use templates and reusable shapes
- Create or save stencils (e.g., Venn diagram, timeline, grid) you can drop into slides to speed annotation.
-
Employ the “reveal” technique
- Hide answers or key steps under a shape you remove as you discuss—this builds suspense and supports stepwise explanation.
-
Encourage learner participation
- Invite students to annotate answers, label diagrams, or vote by marking areas of the screen.
Best practices for different contexts
Classroom teaching
- Start every lesson with a brief roadmap drawn live—students appreciate structure.
- Use annotation for worked examples (math, diagrams, sentence parsing). Record or snapshot annotated slides for revision.
Business presentations
- Annotate during Q&A to capture commitments and action items; save annotated slides as meeting minutes.
- Use remote-friendly tools (shared whiteboards) so offsite attendees can annotate simultaneously.
Workshops and training
- Create interactive exercises where small groups annotate breakout boards and present results.
- Use color-coding to track group responses or progress across tasks.
Recorded lessons / flipped classroom
- Annotate clearly and slowly; learners often rewatch sections. Export annotated video or images as study aids.
Accessibility and inclusivity
- Use high-contrast colors and thick strokes so annotations are visible to viewers with low vision and on low-quality streams.
- Avoid relying solely on color—pair color annotations with labels or shapes for color-blind users.
- Verbally describe what and why you’re annotating for learners who rely on auditory descriptions.
- Provide downloadable transcripts or annotated slide images after the session.
Screen marker etiquette for live sessions
- Tell the audience you’ll be annotating and why—this sets expectations.
- Keep annotations tidy; messy handwriting can confuse.
- Don’t cover important content with your hand or body; position yourself so both you and the screen are visible, or use a document camera/tablet.
- When correcting mistakes, either clearly strike through and rewrite, or erase and redo to avoid confusion.
Saving, sharing, and archiving annotations
- Most digital annotation tools let you export annotated slides as images or PDFs—use these as handouts.
- For live video meetings, use the recording feature and keep a version with annotations for later reference.
- For physical whiteboards or glass boards, photograph the screen straight-on with a high-resolution camera; crop and enhance contrast if needed.
Troubleshooting common problems
- Poor visibility on camera: increase stroke thickness, choose higher-contrast colors, or reposition the camera to reduce glare.
- Lag or jitter with stylus: close unused apps, lower screen resolution during annotation, or use wired connections when possible.
- Accidental erasures: work in layers (duplicate slides) so you can revert, or use “undo” and version history features.
- Ink smearing on a physical surface: switch to wet-erase or test a different surface material; always verify manufacturer guidance.
Quick checklist before a session
- Test projector/camera and annotate tools.
- Charge stylus/tablet and bring backups.
- Prepare blank/low-clutter slides for live writing.
- Select 2–3 marker colors and confirm visibility.
- Decide how annotated materials will be saved and shared.
Example lesson flow (15–20 minute segment)
- 1–2 minute roadmap slide — draw the lesson outline.
- 5–7 minute concept explanation — annotate a diagram or timeline.
- 3–5 minute worked example — solve live, narrating each step.
- 2–3 minute student interaction — invite one or two learners to annotate a slide or answer on-screen.
- 1–2 minute summary — circle the main takeaways and save the annotated slide.
Using a screen marker effectively is about combining technical setup with purposeful pedagogy. When you prepare the environment, choose contrast and color thoughtfully, and use annotations to reveal thinking step-by-step, your presentations and lessons become clearer, more engaging, and easier to remember.
