One of the historical challenges with making graphic novels and using them for teaching and learning is that once designed, they tend to be completely fixed. They do not allow for fixing typos, mistakes, or making edits of any sort.
We tried something different: when composing every page in Adobe Photoshop, we created multiple layers that are independently editable.
Because all of the text and all of the text containers (e.g., speech bubbles) are digital, we can edit, add, or completely remove text from any page.
Because all of the science-related visuals (e.g., thermal partitions) are in a separate layer, we can try a completely different teaching approach.
Because all of the coloring is in a separate layer from all of the inking, we can try different color schemes for environments and characters.
