Carlos received a low grade on his first term paper for his introduction to political science class. he was surprised by the grade because he worked hard on the paper and in the class. he didn't miss a class all term, read all the assigned readings from the textbook, and took excellent notes. he earned an a- on the first exam, so he knew he was grasping the material. in researching his paper, the only readings carlos skipped were recommended magazine and journal articles, which he determined weren't necessary because the topic of his paper was covered very thoroughly in the text. when carlos met with his professor for an explanation, he was told that he received a low grade because his paper was too one-dimensional. his professor felt carlos simply regurgitated the material from the textbook rather than looking to multiple sources for evidence before forming an opinion. carlos needs to work on his skills.
