Start with a clear micro-goal at the top, followed by a single visible action. Use whitespace, contrast, and motion sparingly to direct attention. Avoid cluttered toolbars. Place primary buttons within thumb zones, and let optional depth open progressively when learners request more detail.
Choose examples that avoid stereotypes and resonate across cultures. Provide captions, transcripts, and adjustable speed for every media asset. Write in plain language without diluting nuance. Encourage reflection prompts that welcome different perspectives, and offer alternative formats so everyone can practice comfortably and confidently on any device.
