General chemistry is a gateway course
for most STEM majors, so
student success is a priority for chemistry faculty. Providing quality
information resources for students, including textbooks, is one way
that instructors can support student learning. However, these resources
can be prohibitively expensive for some students, causing them to
opt out of purchasing a textbook or incur stress from the costs of
time and money to obtain a textbook. Open educational resources (OERs)
are no-cost materials, available in the public domain, that students
and instructors can use to reduce the financial burden of college
coursework. However, as chemistry instructors consider adopting OERs,
they may be concerned about the time cost to reframe their courses
around different materials, the risk of negatively impacting student
learning, and whether the benefits to students outweigh those costs
and risks. Although the financial benefits to students have been established,
and the evidence suggests minimal risk of poor academic outcomes,
the cost to instructors continues to be prohibitively high. In this
study, the instructor used a commercial text as the official resource
for the course and offered students a choice to use either the commercial
textbook or an OER textbook. This soft adoption of OERs dramatically
reduced the time cost associated with using the OER for the instructor,
while providing financial benefits to students who chose the OER.
To address the risk that using an OER might negatively impact student
performance, we investigated the impact of student textbook choice
on student performance in general chemistry, controlling for relevant
academic and affective variables. We found that students using OER
performed as well as students using the commercial textbook. With
minimal effort, chemistry instructors can provide a no-cost alternative
for students, with confidence that it will not detrimentally affect
their learning.
