artsedge is a US arts and education network which offers teaching materials for use in and out of the classroom. The site is rich in lesson plans, and instructional articles such as Formal Visual Analysis: The Elements and Principles of Composition by Jeremy Glatstein.
Many of the ideas found in both the ‘how to’ section and the lesson plans would be useful as visual journal exercises. For anyone interested in Arts education there is also numerous articles to browse and think about.
The content in “artsedge” is exactly what I go over in my book as it relates to photography.
