Paperback. Condition: New. Print on Demand. This book presents an in-depth analysis of the prevailing American educational thought on daily school programs during the early 1910s and late 19th century. The author examines fatigue in relation to daily routines, and how it affects students of varying ages and genders. The research draws a connection to mental fatigue, as well as comparing the effectiveness of two different testing methods. By comparing the quantity and quality of work done at different times of day - both before and after a midday break - this book aims to determine whether a decrease in efficiency results from the progress of the day and specifically from schoolwork. The research concludes that fatigue, particularly mental fatigue, likely occurs, and is supported by slight decreases in quality of work. The research presented here is particularly relevant to teachers and educational professionals seeking to optimize school schedules to account for student cognitive function.
