Student Testimonials:
Taken from anonymous surveys distributed by faculty members at the end of the course after implementing the Worldwide Calculus eTextbooks.
“Watching the lectures before class was really helpful and allowed me to grasp the concepts better in class.”
“The videos were extremely convenient. They were basically full lectures that could be watched at any time. When I was comfortable with a concept, I could easily skip through it in the video and move on to harder concepts.”
“I watched the videos when I missed class or didn’t understand the topic well enough. The videos supplemented the material sufficiently and well.”
“I liked the writing, especially how the final theorems were boxed so they were easy to find.”
“The calculus book covers a broad range of topics. The writing in the book is very easy to read and conversational.”
“The explanations of each topic were thorough, especially the proofs. It was good to see it explained in theory and application.”
