How to use the accessibility tools ↓

Good to knowDeaf and hard-of-hearing learners can use every activity, because all content is written and visual, with no sound needed. Teachers of learners with special needs are welcome to share feedback on WhatsApp 0788 804 242.

1. The accessibility button

For everyone

On every page there is a blue tab on the right edge of the screen . Tap it to open the options:

  • A− and A+: make all text smaller or bigger, up to 150%.
  • High contrast: yellow and white on black. Helpful for weak eyesight or reading in bright sunlight.
  • Easy-reading font: clearer letters and wider spacing.
  • Read aloud: the phone reads the page to you.
  • Reset all: back to normal.

Your choices are remembered on your phone, so you only set them once. They work on the quizzes, the practice books and the worked examples.

2. Easy-reading font

For learners with dyslexia or who find reading tiring

  1. Open any page and tap the accessibility tab on the right edge of the screen.
  2. Next to Easy-reading font, tap On/Off. The button turns coloured when it is on.
  3. If the text still feels small, tap A+ once or twice.
  4. Close the options by tapping the round button again.

The special font downloads the first time you switch it on. With a weak connection, a similar clear font is used instead.

3. Read aloud

For partially sighted learners and anyone who prefers to listen

  1. Open a quiz and start a unit.
  2. Tap the accessibility button, then Read aloud.
  3. The phone reads the question, then options A, B, C and D. Each part is highlighted while it is read.
  4. After you answer, tap Read aloud again to hear the feedback and explanation.
  5. Tap Stop reading to stop.

On other pages, Read aloud reads the whole page. To hear only one part, first select the text with your finger, then tap Read aloud.

Use headphones in class. The voice reads English well; most phones do not have a Kinyarwanda voice yet.

4. Screen readers for blind learners

For learners who cannot see the screen

A screen reader is already built into every smartphone. Nothing needs to be installed.

Switch it on

  • Android (TalkBack): Settings → Accessibility → TalkBack → turn on.
  • iPhone (VoiceOver): Settings → Accessibility → VoiceOver → turn on.

Helping learners with special needs

  • Set up the phone together with the learner the first time and practise one unit. Learning the screen-reader gestures takes about 15 minutes.
  • Let learners work at their own pace: the quizzes have no time limit.
  • Deaf and hard-of-hearing learners can use every activity as it is: all content is written and visual, and no sound is needed.
  • Diagrams in the worked-solution PDFs are pictures. For blind learners, describe them aloud or prepare raised (tactile) drawings.
  • Send your feedback and ideas on WhatsApp to 0788 804 242.
