Because undergraduate participation in research is a longstanding and increasingly important aspect of the career path for future scientists, students can benefit from additional resources to introduce them to the culture and process of research. We suggest the adoption of the web resource "Astrobites" as a classroom tool to increase the preparation of undergraduate physics and astronomy students for careers in research. We describe the content and development of the website, discuss previous university courses that have made use of "Astrobites," and suggest additional strategies for using "Astrobites" in the classroom.
