Please schedule a time to get the book -- print or online -- and engage with the material. Then post online reviews.
I participated in the @Wolfram U live sessions using this text earlier this year. I just posted the first review of the print book on Amazon. This text -- with the Wolfram Language -- is a tremendous place to apply Bloom's Taxonomy [revised]:
Listening to the lecture while working/playing in a scratch notebook is a great way to remember/understand the principles. Exercises/quizzes provide a helpful environment to analyze and apply the concepts. Students can naturally make the leap to create something new out of these lessons. I particularly like the idea of homeschoolers teaching with @Devendra's book: older learners working with younger siblings -- fortifying the lessons for both parties.
Students are also learning the universe of the Wolfram Language. I particularly like how students can evaluate the examples in the Documentation Center, change them subtly, or go off on a tangent with something completely different. Each documentation page is its own little sandbox; using the documentation in the context of these learning models is very powerful. Do beginners have an obvious way to load a documentation entry into a Wolfram Cloud account to access that playground? I've never tried to do that. Students can also use Wolfram on a Raspberry Pi to get direct access to this computational playground.
Is it useful to have both a print and online version of the course? Yes! Learning is a mysterious thing; physically touching a book tickles the neurons in a different way. Some homeschool teachers like teaching offline with no computers for parts of the lesson. There could even be a hybrid model: listening to an audio-only version of Devendra's lectures while viewing the material in the print book.
Please review the text. Please let people know about this wonderful alternative way to learn. Thanks!
