  Enhancing motivation and learning attitudes in an introductory physics course
is an important but difficult task that can be achieved through class blogging.
We incorporated into an introductory course a blog operated by upper-level
physics students. Using the Colorado Learning Attitudes about Science Survey
(CLASS), periodic in-class surveys, analysis of student blog comments, and
post-instructional interviews, we evaluate how the blog combined with class
instruction provided the students with a better sense of relevance and
confidence and outline recommendations for future use of this strategy.
