Lesson Opening Designer

What This Skill Does

Generates an evidence-based lesson opening comprising three components: a retrieval practice starter that reviews previous learning, a prior-knowledge bridge that connects what students already know to today's new content, and a learning intention framing that sets purpose without revealing all answers. The output is a complete timed script for the first 8–12 minutes of a lesson. AI is specifically valuable here because effective lesson openings must simultaneously serve three functions (retrieval, activation, framing) within a tight time constraint, and the retrieval questions must be carefully chosen to target the most important prior knowledge for today's lesson — not just "what we did last time" but specifically the knowledge that today's lesson will build on.

Evidence Foundation

Rosenshine (2012) places daily review as Principle 1 of effective instruction: "The most effective teachers began their lessons with a five-to-eight-minute review of previously covered material." This serves two purposes — strengthening retention through retrieval practice and activating the prior knowledge schemas that new learning will attach to. Ausubel (1960) demonstrated that advance organisers — conceptual frameworks presented before new content — significantly improve learning by providing "ideational scaffolding" that helps learners organise incoming information. Marzano (2007) identified that connecting new content to prior knowledge is a foundational instructional strategy, but only when the connections are made explicit (not assumed). Agarwal et al. (2012) showed that brief retrieval practice at the start of lessons improves retention with minimal time cost — even 5 minutes of retrieval produces measurable benefits. Hattie (2009) identified prior knowledge as the single strongest predictor of new learning — what a student already knows determines what they can learn next.

Input Schema

The teacher must provide:

• Today's topic: What will be taught today. e.g. "Adding fractions with unlike denominators" / "The causes of World War I: the alliance system" / "Writing a balanced argument paragraph"
• Previous learning: What was recently taught that connects. e.g. "Last lesson: equivalent fractions. Last week: adding fractions with like denominators" / "Last lesson: the assassination of Archduke Franz Ferdinand"
• Student level: Year group. e.g. "Year 8"

Optional (injected by context engine if available):

• Opening time: Minutes available (default 10)
