Your workbook should be a comprehensive document that illustrates your artistic development and research. The purpose of the workbook is to encourage and record personally driven research and discovery that function interactively with independent art work.
The current IB curriculum requests a digital submission with screens – which can be confusing on how to approach the Visual Arts Journal. In my IB class, I suggest that at the very least, students use the Visual Art Journal as a sketchbook to collect brainstorming, idea development and compositional studies. Documentation of Process, Art analysis and reflections can be added more easily (and with more space and depth) digitally.
