LessonNote is the best tool for documenting the flow of a lesson and its impact on students. LessonNote lets you track who is talking to whom, when, and for how long, and lets you jot handwritten notes about what is being said and what students are doing. LessonNote can also record photos of student work.

Create a seating chart, which may include a teacher, students, groups, and display areas (such as chalkboards). Record observations by tapping on an entity, or drag from one entity to another to record an interaction. Take photos or insert existing photos into your notes. Use a "seating chart note" to quickly make notes about multiple students.

When you review your notes, a dynamic seating chart display highlights whom a note was about, while a timeline provides a birds-eye view of the lesson, showing when events occurred and how long they lasted.

LessonNote helps users record factual, non-judgemental observations of individual events and behavior. Tested through Lesson Study, it is ideal for peer observations and for coaching. For administrators needing to evaluate teachers, it improves on simple checklists by helping document how lessons affect students—which is, ultimately, what teaching is all about.

Work with colleagues and use LessonNote to improve teaching and learning!

Before the lesson

  • Create a classroom: add students (generic, male, female), tables (groups), teachers and displays
  • Save the classroom for future lesson observations

During the lesson

  • Tap anything in the classroom to record a time-stamped note
  • Track lesson and interaction duration
  • Tap and drag between entities to record interactions
  • Take photos* or add existing photos to notes *requires iPad 2

After the lesson

  • Review and edit lesson notes
  • Examine patterns, timing, and interactions
  • LessonNote facilitates non-judgmental discussion around how a lesson affected students.

Lesson Note pro

LessonNote Pro is a web-based companion to LessonNote that provides important additional capabilities for administrators, instructional coaches, researchers, and others who routinely use LessonNote in their work. It is also for teachers who record anecdotal notes about their students' learning.

Lesson Study

Lesson study is a way to explore new teaching ideas through a single carefully-planned "research lesson." After the lesson, the planning team and observers discuss how the lesson impacted the students and how the lesson could be improved. Through this one lesson, participants gain new insights into teaching and learning.

"Lesson Study is by far the best form of professional development I have ever seen."

The design of LessonNote has been shaped by the accumulated knowledge of Japanese educators, based on over 100 years of using lesson study to improve teaching and learning, and by the experiences of educators implementing lesson study around the world.
