> Framing education as lessons presumes that lessons are how people learn
To clarify, are you thinking of a lecture instead of a lesson? A lecture is "a speech read or delivered before an audience or class, especially for instruction or to set forth some subject" whereas a lesson is "a section into which a course of study is divided".
A lesson is a generic term agnostic to instructional style (e.g., explicit, discovery, project-based, etc.) Similar to how everything in software engineering is a "task" :).
