Evaluating Sources Addressing Sleep and Performance Sleep loss and shifting sleep patterns are known to be widespread on college campuses across the United States and around the world in general. However, while there are many studies relating sleep to performance, a much smaller number of studies focus on analyzing these sources as they would prove useful when researching and writing about the idea of ​​sleep and its correlation with academic performance, an article titled “Sleep-Wake Patterns and Academic Performance in University Students,” presented at the European Conference on Educational Research, was found to be overall the most useful source for researching the topic. While points, statements and statistics can be found within all of the sources used for research, the sheer amount of studies and works cited within the “Sleep-Wake” document lends weight to its usefulness as a reliable source. One of the other factors of sleep and its impact within the university community. Three different sources for criteria and utilities that related to this topic were found and investigated. sources, “College Students try to Cheat Sleep Needs,” a college newspaper, offers basic facts and elementary assumptions such that they could be found in any biology textbook or encyclopedia. These references cover things like sleep cycles and sub-phases and the general consequences of an unbalanced sleep cycle. The study by the Biological Rhythm Research authors, however, hints at previous studies and findings that “several factors, such as social and academic demands, part-time jobs, […] influence the sleep-wake cycle of college students ”. but then it simply states the results of a particular study, and does so in the midst of paper sources. As demonstrated by its completeness, attention to detail and reliability by its specialized authors, this article is the most useful place for information on the topic.
