What are the four most prominent features of an effective lesson?

From the Archives 001: In this episode of Thinking Deeply about Primary Education we're diving into the archives to retrieve some of the most inspirational responses to questions posed over the last few years. This week, Lloyd Williams Jones shares the four most prominent features of his lessons, along with his thoughts on effective teaching. This was the very first question I asked on TDaPE and I wonder if Lloyd has changed his mind on anything over the last four years. I'll ask him to share his thoughts in the comments, and it would be great if you could do the same.
