What's the most important benefit to lesson study?
You develop the eyes to see children.
~ A Japanese elementary principal (Lesson Study: A Handbook of Teacher-Led Instructional Change by Catherine Lewis, p. 27)
What does it mean to "see students"? Why is it important to develop the eyes to see students? And how does lesson study promote this capacity in teachers? At the college level, the phrase “seeing students” brings to mind national surveys and reports (e.g., NSSE and CIRP) that describe college students’ beliefs, social attitudes, and academic behavior, including the Beloit College Mindset List which lists generational touchstones and benchmarks for each new freshmen class (e.g., For the class of 2009 born in 1987, “Starbucks, souped-up car stereos, telephone voicemail systems, and Bill Gates have always been a part of their lives”). These provide a broad range of information about students as a cohort or group. “Seeing students” also brings to mind understanding students as people—their interests, goals, lives—as a result of getting to know them in and outside the classroom.
But “seeing students” has a more specific meaning related to classroom teaching. In this case it is seeing and understanding how they learn and think as they interact with the subject matter, trying to make sense of the material, solve problems, interpret new ideas, make decisions, and so forth. I believe this is the form of seeing the Japanese elementary school principal has in mind.
Is it important for teachers to understand how students learn and think? If a teacher’s major aim is to advance student learning and thinking, then understanding how they learn is indispensable. Most good teachers recognize that their students rarely achieve deep understanding of the subject matter, and there is almost always a sense at the end of a class period or a course that teaching and learning could be improved. In order to improve their teaching, teachers need to know why students didn’t learn or didn’t “get it.” Without some insight into student learning and thinking, teaching improvement is pretty much guesswork. Being able to “see” the subject from students’ point of view can help teachers understand what kinds of problems, difficulties and misconceptions students are likely to have. Knowing what makes a topic difficult for a student can help teachers design instructional activities, develop explanations, and give feedback more directly attuned to the problem. To illustrate consider teachers who are adept at explaining difficult concepts to students. They seem to be aware of what makes a concept difficult for students to understand, and base their explanations on how students (novices) might understand the concept, rather than on how the teacher (expert) understands it. Teachers who do not have this kind of “cognitive empathy” are more likely to explain concepts as if they are talking to themselves or to another expert on the subject.
How does lesson study develop the eyes to see students? How students learn and think seems to be at the center of Japanese lesson study. In planning a research lesson teachers anticipate and predict how students are likely to interpret and respond to parts of the lesson. During the lesson their observations focus on how students experience, interpret and make sense of the subject. And, their post-lesson discussions analyze student thinking in depth and detail. Imagine the rich and varied insights into student learning and thinking one might develop by doing lesson study regularly throughout one’s teaching career. In many accounts of lesson study, Japanese teachers reveal a keen sense of how their students learn and think and use that knowledge to design, observe, analyze and refine class lessons.
