This is going quick, and it is enjoyable and easily read. Nice use of teacher reflections to elaborate on the idea that all classroom experience is different and that teachers all have different goals in order to understand or evaluate their students' learning. Carry this over to what assessment is or can be, and then if you want (although it is outside the scope of this book and the research I will be engaged with immediately) you can maybe carry this over into our own interactions with the world, i.e. what we perceive and what we think we perceive, how we assess our movement through community and place compared to how we improve the quality of that movement and those interactions. Ask me if this isn't clear. This book is probably much clearer (on everything except my last point... that isn't covered here!)
