Teach Computer Science

We are a community of teachers that have developed extensive computing resources primarily aimed at the English secondary school curriculum that can be accessed here: www.mangolearning.academy .  Mango learning empowers teachers to deliver great lessons that explain complex ideas using clear and highly scaffolded teaching and learning resources. We are very excited to offer these resources for free to the community. These teaching and learning resources for computing are made by teachers for teachers and we understand the day-to-day challenges that teacher face.   The resources incorporate general and computing specific evidence-based pedagogy. We incorporated spaced retrieval practice though knowledge organisers, diagnostic questions and quizzes, for instance. We also incorporate ideas from cognitive load theory through lots of worked examples.   To help with coding we use PRIMM and block to text based pedagogical approaches.   To support literacy we address ...

In the previous post we looked at the transfer of learning from block based coding to text based languages.  Semantic waves offer a theory that help us to structure our lessons to support transfer of learning (Maton, Waite et al).  When we present concrete examples in single contexts transfer of learning is going to be weak.  We need to present multiple examples in a range of context.  This allows us to abstract out the underlaying features.  This idea of moving along a continuum between the abstract and concrete is given by the term semantic gravity.  For instance, if we talk about an algorithm in abstract terms we might say that it is a sequence of steps to solve a problem.  At this stage we have presented it as an abstract idea so has low semantic garvity.  In a lesson we might then go on and write algorithms for drawing squares.  This represents a concrete episode with high semantic gravity.  In a good lesson we might also want to gi...

When we move students on from block to text programming, we want to transfer the learning that they have made on block coding into text programming.   When we are transferring learning we want to transfer knowledge from one context into another. In moving from one context to another we need to think in an analogical manner such that when we know how to solve a problem in one domain we can use it to help us solve a problem in another domain. The use of analogous examples helps learners see the deeper structure. We do this by seeking out deep structures and remove the surface structure of a problem. This approach is called expansive framing and we have expectation of future use in a different context. In contrast, bounded framing does not have utility beyond the current learning. Current learning needs to make connections to earlier contexts from which learners are expected to transfer in knowledge to the new context. Transfer of learning does not happen by itself; the teacher ...
