Repetition Effects Over The Years

After more than 20 years of research, this is the first book-length treatment of second language task repetition – the repetition of encounters with a task that involve re-using the same content with the same overall purpose. The topic links task performance with the growing mastery of both the task and of relevant language, and constitutes a site with special potential to promote learning within and across language lessons, and for preparing students for assessment and of course real-world language performance. The volume assembles chapters that complement each other in interesting ways: significant background reviews, studies of patterns of change across task repetition iterations, and reports on the use and nature of task repetition in language classes in on-going programmes. Contributors draw on a variety of interpretive frameworks and report from a range of language educational contexts. The volume will be of interest to language researchers, teacher educators, teachers, and students, as well as others interested in the contribution of task repetition to learning.

In the past decade, few subjects at the intersection of medicine and sports have generated as much public interest as sports-related concussions - especially among youth. Despite growing awareness of sports-related concussions and campaigns to educate athletes, coaches, physicians, and parents of young athletes about concussion recognition and management, confusion and controversy persist in many areas. Currently, diagnosis is based primarily on the symptoms reported by the individual rather than on objective diagnostic markers, and there is little empirical evidence for the optimal degree and duration of physical rest needed to promote recovery or the best timing and approach for returning to full physical activity. Sports-Related Concussions in Youth: Improving the Science, Changing the Culture reviews the science of sports-related concussions in youth from elementary school through young adulthood, as well as in military personnel and their dependents. This report recommends actions that can be taken by a range of audiences - including research funding agencies, legislatures, state and school superintendents and athletic directors, military organizations, and equipment manufacturers, as well as youth who participate in sports and their parents - to improve what is known about concussions and to reduce their occurrence. Sports-Related Concussions in Youth finds that while some studies provide useful information, much remains unknown about the extent of concussions in youth; how to diagnose, manage, and prevent concussions; and the short- and long-term consequences of concussions as well as repetitive head impacts that do not result in concussion symptoms. The culture of sports negatively influences athletes' self-reporting of concussion symptoms and their adherence to return-to-play guidance. Athletes, their teammates, and, in some cases, coaches and parents may not fully appreciate the health threats posed by concussions. Similarly, military recruits are immersed in a culture that includes devotion to duty and service before self, and the critical nature of concussions may often go unheeded. According to Sports-Related Concussions in Youth, if the youth sports community can adopt the belief that concussions are serious injuries and emphasize care for players with concussions until they are fully recovered, then the culture in which these athletes perform and compete will become much safer. Improving understanding of the extent, causes, effects, and prevention of sports-related concussions is vitally important for the health and well-being of youth athletes. The findings and recommendations in this report set a direction for research to reach this goal.

The effects of repetition and spaced review in programed instruction were studied. Experiments 1 and 2 covered a one-semester course in General Science at the Junior High School level. In Experiment 3, a 1280-frame portion of the total course was used. In Experiments 1 and 2, comparisons were made among (a) a conventional course, (b) a regular linear version of the program, and (c) a spiral version of the program. The results indicate that the programed course was at least as effective as the conventional instruction in terms of both learning and retention after 15 weeks. The linear program was superior to conventional instruction on some measures. The spiral program offered few, if any, advantages over the regular linear program. Experiment 3 allowed a more precise evaluation of the separate effects of repetition and spaced review. Spaced review produced significant increases in learning which persisted, and even increased, through a 3-week retention interval. Repetition did not produce increased learning or retention. The general conclusions are: (a) repetition of instructional materials above the usual level in a linear program is not beneficial; (b) spaced review is potentially beneficial; and (c) some techniques of obtaining spaced review, eg, spiral programing, may offer disadvantages that equal or outweigh the potential advantages of spaced review.
