Enhance Reading Comprehension: A Guide to Digital Reading Windows

“Chunking” is a reading strategy that involves breaking up a long page of text into smaller parts. This helps you to process information in small bites. When reading online text, try a free digital reading window (also called a reading ruler) to isolate text and boost reading comprehension.

You can try the free Line Focus tool in Immersive Reader built into Microsoft applications (use your free Microsoft account). When enabled, the Line Focus tool will keep a single line, or if you prefer a few lines of text, in focus and darken the remainder of the screen.

By design, you are in control of moving the reading window through the page of text. Therefore, you can take your time comprehending and processing the information line by line or section by section.

Also, keep offline solutions in your environment when reading paper materials or when technology is unavailable (no battery power or lost WiFi connection). For example, have a physical reading window/reading guide or paper cutout to create a focus area.

  • Improves focus and concentration
