I found the first chapter very interesting in making the case for a rigorous course of study. I think what I found the most impacting sentence in the entire chapter was found on page 6. "It is important for us to challenge our students, but we must do so in a way that ensures their success, rather than reinforcing their negative feelings." As a chemistry teacher (so I apologize in advance for the lack of correct grammar in my posts), I feel that there is so much negativity surrounding the subject matter that it is incredibly important to be upfront about the rigorous nature of the course, but to also be encouraging and supportive throughout the semester as well.
