Short-term professional learning that focuses on beliefs and practice: Improvements in preschool teachers’ ongoing literacy practice     

Jacqueline Lynch 《Journal of Early Childhood Teacher Education》2017,38(2):164-181

An intervention study was conducted with preschool teachers to address their beliefs and practice in the area of language and literacy. A total of 27 preschool teachers, each from different early childcare centers, participated in three 1-day professional learning sessions over the course of 9 months. Learning sessions focused on three different language and literacy topics. Study participants completed a pre- and post-session questionnaire and were observed in the classroom before and after each session. Significant differences were observed in both their beliefs and practice after the intervention. Specifically, preschool teachers’ beliefs were related to their practice in two areas: oral language and vocabulary; and book reading. Based on the data, a focus on beliefs and practice in future short-term PL or workshop models may support successful outcomes in teaching practice.  相似文献

Impact sports and bone fractures among adolescents

The objective of the present study was to investigate the effects of different sports on stress fractures among adolescents during a 9-month follow-up period. The sample was composed of 184 adolescents divided into three groups (impact sports [n = 102]; swimming [n = 35]; non-sports [n = 47]). The occurrence of stress fracture was reported by participants and coaches. As potential confounders we considered age, sex, resistance training, body composition variables and age at peak of height velocity. There were 13 adolescents who reported fractures during the 9-month period. Bone mineral density values were higher in adolescents engaged in impact sports (P-value = 0.002). Independently of confounders, the risk of stress fracture was lower in adolescents engaged in impact sports than in non-active adolescents (hazard ratio [HR] = 0.23 [95% confidence interval (CI) = 0.05 to 0.98]), while swimming practice was not associated to lower risk of fracture (HR = 0.49 [95% CI = 0.09 to 2.55]). In conclusion, the findings from this study indicate the importance of sports participation among adolescents in the reduction of stress fracture risk, especially with impact sports. More importantly, these results could be relevant for recognising adolescents in danger of not reaching their potential for peak bone mass and later an increased risk of fractures.  相似文献

Examining the effects of a highly rated science curriculum unit on diverse students: Results from a planning grant     

Sharon Lynch  Joel Kuipers  Curtis Pyke  Michael Szesze 《科学教学研究杂志》2005,42(8):912-946

This article reports on the results of a planning grant studying the effects of a highly rated curriculum unit on a diverse student population. The treatment was introduced to 1500 eighth grade students in five middle schools selected for their ethnic, linguistic, and socioeconomic diversity. Students were given pre‐, post‐, and delayed posttests on a Conservation of Matter Assessment and measures of motivation and engagement. This quasi‐experiment found statistically significant posttest results for achievement, basic learning engagement, and goal orientation. Analyses of disaggregated data showed that subgroups of students in the treatment condition outscored their comparison group peers (n = 1500) in achievement in all cases, except for students currently enrolled in ESOL. Analysis of video data of a diverse group of four students as the unit was enacted suggests that students entered a learning environment that permitted them to function in different, but consistent ways over time; that is, the frequency of students' manipulation of objects showed a different pattern of engagement for each of the four students compared with patterns of verbal responses such as the use of scientific terms. The results of this planning grant paved the way for a large study of the scale‐up of highly rated curriculum units. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 912–946, 2005  相似文献

Secrecy agreements and national security     

Mark H. Lynch 《Government Information Quarterly》1984,1(2):139-156

In the spring of 1983, President Reagan issued a National Security Decision Directive which, among other provisions, mandated that present and future Executive Branch employees and contractors having access to classified information or sensitive compartmented information, the latter being a kind of intelligence data, sign one of two types of nondisclosure agreement. Previously, these types of agreements had been used for the most part only in the intelligence agencies. This article reviews the law which has developed around the prepublication review requirement of Central Intelligence Agency agreements and examines the contracts mandated by the new National Security Decision Directive, identifying issues raised by these agreements in light of the body of case law dealing with the C.I.A.'s system of censorship. With regard to the prepublication review requirement, the focus here is limited to former rather than current officials of the government.  相似文献

Sorting of textual data bases: A variety generation approach to distribution sorting     

David Cooper  Mary E. Dicker  Michael F. Lynch 《Information processing & management》1980,16(1):49-56

A method of sorting large textual data-bases by computer using external storage is proposed. The range of sort-keys in a sample of data to be sorted is divided into a fixed set of partitions, which should also give an adequate representation of new data from a similar source. The partitions are composed of ordered key ranges. An incoming data stream is distributed into a series of bins according to the partition in which the key lies, and the bins are then seperately sorted, using an internal sort, to give an ordered file. It is shown how the number of disc accesses needed depends on the manner in which the bins become filled, and thus on statistics of the data. Experiments using an INSPEC data-base give information on which estimates of the efficiency of the method can be based.  相似文献
