Each textbook may have things that they do differently. Sometimes there are synonyms of different ideas, which we include in our lessons. Students may not always hear topics in the same way so this approach can be beneficial.
We research a bunch of textbooks ahead of time before building any content, so we are always adjusting the information. In order to help students understand we use phrases like "sometime it is called this, but more commonly called this."
Some textbooks will teach a topic differently, like General Chemistry vs. GOB. We look at curriculum differences and when needed build different versions of videos to accomodate different learning objectives.
