Scholarly materials are preferred in college level work because these types of materials utilize proven research methods to study a subject and both the research and conclusions have been judged sound by a group of the researcher's peers.
In this way the work is transparent -- you can go back to the same sources or replicate the study yourself because you know the process the original researcher used.
This is not true of "popular" or non-scholarly materials.
Popular materials are sometimes used in academic research, usually as primary sources.
