Daniel T. Willingham's Why Don't Students Like School? is a must-read for all trainees. Willingham provides a research-based analysis of teaching, learning, and school practices based on cognitive science. He discusses student engagement, learning retention, "drilling" and other relevant cognitive matters to ensure your students like school or, at least, your lessons.
The Classroom Instruction That Works by Bryan Goodwin & Kristin Rouleau focuses on teaching and learning more broadly. It is a meta-analysis of selected teaching and learning research and the conclusions that can be drawn from it. It provides useful teaching practices concerning student engagement, learning retention, and learning phases.
Elizabeth Jorgensen's Hacking Student Learning Habits is an introduction to process-based learning (PBL) and how to implement it gradually in your lessons. In a system that largely focuses on outcomes and learning objectives, the learning process often takes second place to the detriment of actual learning. Hacking Student Learning Habits offers an alternative to this that focuses on the process of learning and its relevance.
