Challenge, deliberate practice, and interleaving are techniques that can help students learn computing skills. Challenge provides goals tailored to different ability levels. Deliberate practice involves revisiting skills in multiple ways to reinforce learning. Interleaving intersperses different topics in lessons and tests to improve long-term retention of information. These techniques will be applied at Lady Lumley's School by setting skills starters and short tests at the beginning of lessons to challenge students and strengthen their computing knowledge.
