This study integrated an in-house audience response system (ARS) in the human anatomy course over two years to determine whether students performed better on high-stakes examinations following exposure to similar interactive questions in a large lecture format. Questions in an interactive ARS format were presented in lectures via PowerPoint presentations. Students who chose to participate in the anonymous ARS sessions submitted answers via their personal wireless devices (e.g., laptops, smartphones, PDAs, etc). Students were surveyed for feedback. Student participation in ARS activities was greatest (65-80%) in the first lecture. The number of students who actively participated in ARS activities decreased over the next four sessions, and then slightly increased in the last two sessions. This trend was the same for both years. Use of the ARS did not dramatically enhance overall student performance on examination questions that dealt with content similar to content presented in the ARS sessions. However, students who scored in the lower quartile of the examination performed better on the examination questions after the ARS was implemented. Accordingly, our findings suggest that the effect of ARS to improve student performance on examinations was not uniform. The overall benefit of an ARS to enhance the lecture experience was confirmed by student surveys.  相似文献   

Innovative activities for teaching anatomy of speech production     

Amy E. Skinder‐Meredith 《Anatomical sciences education》2010,3(5):234-243

Courses in anatomy have traditionally relied on lectures and cadaver dissection laboratories. In speech and hearing sciences, there tends to be less access to cadavers than in medical schools and other allied health professions. It is more typical to use anatomical models, diagrams and lecture slides. Regardless of the resources available, anatomy is a subject that lends itself to hands‐on learning. This article briefly reviews teaching methods and describes a variety of innovative activities to enhance learning of anatomical concepts and clinical relevance of anatomy for speech production. Teaching strategies and activities were developed to capitalize on students' multimodal learning preferences as revealed by responses to a survey administered to 49 undergraduates in the beginning of an anatomy of speech production course. At the end of the semester, students completed a second survey. A five‐point Likert scale was used to assess the usefulness of each activity as a learning tool or level of clinical relevance and the level of enjoyability. The responses were overwhelmingly positive with level of usefulness and level of clinical relevance rated higher on average than the level of enjoyment.

Background:Active video games are a new method for increasing physical activity(PA).Fully immersive virtual reality(VR)is a hardware device on which an active video game can run.Active(video games in)VR(AVR),might increase immersion,game engagement,and moderate-to-vigorous PA(MVPA),thereby yielding greater exercise-related benefits,e.g.,cognitive performance.Methods:We examined the induction of MVPA via an AVR and a sedentary VR(SVR)as well as the effects of VR play on cognitive performance,which was monitored using 2 different methods.Each of 29 sedentary college students attended three 20-min laboratory sessions(AVR,SVR,or control)in a randomized order;during the control session,they sat quietly doing nothing.A fully immersive headset was used for the 2 video game sessions.We monitored and computed participants’PA using hip-wom accelerometers(wGT3 x-bt;ActiGraph,Pensacola,FL,USA)and a heart rate band(Polar H7;Polar,Kempele,Finland).After each session,the participants completed a mnemonic similarity test(MST)to measure recognition memory.They also filled out a motion sickness questionnaire and an abbreviated game experience questionnaire.Results:The AVR session induced a significantly greater heart rate and more time spent in MVPA than did either of the other 2 sessions regardless of the PA monitoring method.AVR elicited greater game experience questionnaire-assessed sensory and imaginative immersion,challenge,and positive affect than did SVR.The mnemonic similarity test recognition score was marginally higher post-AVR session than it was post-SVR session.Conclusion:AVR elicited MVPA without a significant increase in motion sickness and induced a better game experience and better borderline cognitive performance than did SVR.  相似文献   

Reinforcing contingencies for sex-role behaviors in preschool children     

Boyd R McCandless  Carol Bush  Ayse Ilgaz Carden 《Contemporary educational psychology》1976,1(3):241-246

Two groups of disadvantaged Afro-American children, a total of 30 boys and 25 girls, mean age about 42 months; and two groups of middle- and upper-middle-class children, most of them white, 35 boys and 31 girls, mean age about 44.5 months, were observed for patterns of sex-role-characteristic behavior and peer and teacher response to such behavior. At all times, the children in the two experimental groups were being taught by seven women and seven or eight men, about half of whom were Afro-American, half white-Anglo, and who were mixed in the two schools by race but evenly divided by sex. Boys engaged in 16% sex-characteristic behavior, 5.7% cross-sex behavior. The same figures for girls were 18 and 6%. There were no pattern or percentage differences by race or social status of children. Women teachers gave most of their sex-role connected rewards for feminine behavior to both boys and girls. Men teachers rewarded more equably, masculine behaviors for boys, feminine behaviors for girls. Children rewarded mainly their own sex, and gave rewards for sex characteristic behavior. The pattern was even clearer for boys than for girls. In Discussion, comparisons are made with other somewhat similar studies.  相似文献

Mission matters: The cost of small high schools revisited     

Leanna Stiefel  Amy Ellen Schwartz  Patrice Iatarola  Colin C. Chellman 《Economics of Education Review》2009,28(5):585-599

With the financial support of several large foundations and the federal government, creating small schools has become a prominent high school reform strategy in many large American cities. While some research supports this strategy, little research assesses the relative costs of these smaller schools. We use data on over 200 New York City high schools, from 1996 through 2003, to estimate school cost functions relating per pupil expenditures to school size, controlling for school output and quality, student characteristics, and school organization.We find that the structure of costs differs across schools depending upon mission—comprehensive or themed. At their current levels of outputs, themed schools minimize per pupil costs at smaller enrollments than comprehensive schools, but these optimally sized themed schools also cost more per pupil than optimally sized comprehensive schools. We also find that both themed and comprehensive high schools at actual sizes are smaller than their optimal sizes.  相似文献   

Owning Your Emotions: Reactions to Expressions of Self- versus Other-Attributed Positive and Negative Emotions     

Amy M. Bippus  Stacy L. Young 《Journal of Applied Communication Research》2005,33(1):26-45

This investigation tested the notion that speakers should own their emotions by using I-messages rather than You-messages when conveying their feelings. In Study 1, hypothetical self-attributed (I) emotion messages were compared to other-attributed (You) messages, with an I-You message added in Study 2. In both studies, the effect of both positive and negative emotion statements on perceived politeness, effectiveness, and emotional reactions were assessed. No differences were found in reactions to the message forms for negative emotions, but both studies provided evidence for differences in respondents' reaction to positive emotional expressions. These results suggest a self-serving bias; recipients do not distinguish between ways of phrasing negative emotions expressed to them, but apparently appreciate being given credit for speakers' positive emotions. Implications for therapists, communication consultants, and practitioners are discussed.  相似文献

An NCME Instructional Module on Multistage Testing     

Amy Hendrickson 《Educational Measurement》2007,26(2):44-52

Multistage tests are those in which sets of items are administered adaptively and are scored as a unit. These tests have all of the advantages of adaptive testing, with more efficient and precise measurement across the proficiency scale as well as time savings, without many of the disadvantages of an item-level adaptive test. As a seemingly balanced compromise between linear paper-and-pencil and item-level adaptive tests, development and use of multistage tests is increasing. This module describes multistage tests, including two-stage and testlet-based tests, and discusses the relative advantages and disadvantages of multistage testing as well as considerations and steps in creating such tests.  相似文献
