LessonNote is an innovative classroom observation tool for documenting the flow of a lesson and its impact on students. Capture both quantitative and qualitative data: • Track who is talking to whom, when, and for how long. • Jot handwritten, time-stamped notes about what is being said and what students are doing. • Take photos of student work. • Capture time spent in different modalities: whole-class, individual work, group work. Begin by creating a seating chart with icons representing the teacher, students, groups, and display areas such as blackboards or projection screens. Record observations by selecting an icon, or linking two icons for a note about an interaction. Take photos of student work. After a lesson, efficiently review your data for a student-focused conversation that improves teaching and learning. A small seating chart shows exactly who or what a note is about, so you don't need to know the names of the students. A timeline shows how much time was spent in whole-class lecture or discussion, individual work time, and group work time. LessonNote helps you create a fact-based and non-judgemental record of the lesson and its impact on students. LessonNote is ideal for peer observation, coaching, instructional rounds, and of course for Lesson Study. For administrators, LessonNote improves on simple checklists or rating scales by helping document how lessons affect students—which is, ultimately, what teaching is all about. Work with your colleagues and use LessonNote to improve teaching and learning! Read the Terms of Service at: https://LSAlliance.org/LessonNote/terms-of-service.html.
