| Summary: | 碩士 === 國立臺南大學 === 數位學習科技學系碩士班 === 101 === This research examines the influences of different background noises on elementary school student’s attention span and learning achievements by analyzing subjects’ brain waves.
In the field of Cognitive Neurosciences, attention span refers to the ability of concentrating on one activity constantly while at the same time ignoring any disturbances that derived from outside environment. This research conducts three experimental situations when subjects (3rd grade elementary students) are watching video film “Go play at Mangrove: examining how much you know about the wetlands” in order to observe different brain waves. The brain waves collected are simultaneously transmitted to computer to be illustrated by different degrees of attention span and relaxation. Other methodologies such as user records, storage, attention span and relaxation graph analysis are also applied to this research. This research analyses subjects’ physiological signals by adopting EEG ASIC Chips and Grain Computer Interface; subjects’ brain waves revealed on computer screen are categorized by difference background noise interferences.
The subjects of this research are 3rd grade elementary students from two local schools in Tainan City. The results reveal that female students’ attention span are generally higher than that of male students’. Besides, the degree of attention span correlates positively with test results. The higher degree the attention span is, the better the test results becomes. Regarding the background noise interferences, this research concludes that (1) quiet environment has no influence on elementary students’ attention span and test results; (2) Mozart’s symphony #40 with a sound level of 70 decibels has a negative influence on elementary students’ attention span and test results; (3) factory noise with a sound level of 70 decibels has an adverse influence than the above two situations on elementary students’ attention span and test results.
