Authors’ Comments
“We have relied on WebAssign for more than a decade to give our students immediate feedback as they learn to solve complex problems, as well as practice basic skills. We have coded many problems ourselves, and appreciate how easy it is for instructors to create their own WebAssign questions. WebAssign’s seamless interface lets us respond quickly to students’ questions about homework, and offers students economical access to the electronic version of our textbook.”

Instructor Testimonials
“The pairing of Matter and Interactions with WebAssign allows for homework assignments that naturally reinforce lessons from the book. For example, WebAssign can automatically generate new versions of a problem related to the Einstein model of a crystalline solid, assigning students ‘their own’ element of the periodic table. Then, students can request a second version of the same problem with a new element: this allows them to see for themselves which aspects of the problem are universal, and which depend on particular details of the atom selected.”

“WebAssign enables me to collect problems, questions, and VPython resources for Matter & Interactions all in one place where students can access them all without having to visit multiple websites. The convenience, along with WebAssign’s existing features, makes it an excellent M&I headquarters during the semester.”
