Effects of an Educational Experience Incorporating an Inventory of Factors Potentially Influencing Student Acceptance of Biological Evolution

This investigation provides an extensive review of scientific, religious, and otherwise non-scientific factors that may influence student acceptance of biological evolution. We also measure the extent to which students' levels of acceptance changed following an educational experience designed to address an inclusive inventory of factors identified as potentially affecting student acceptance of evolution (n = 81, pre-test/post-test) n = 37, one-year longitudinal). Acceptance of evolution was measured using the Measure of Acceptance of the Theory of Evolution (MATE) instrument among participants enrolled in a secondary-level academic programme during the summer prior to their final year of high school and as they transitioned to the post-secondary level. Student acceptance of evolution was measured to be significantly higher than initial levels both immediately following and over one year after the educational experience. Results reported herein carry implications for future quantitative and qualitative research as well as for cross-disciplinary instruction plans related to evolutionary science and non-scientific factors which may influence student understanding of evolution.     

Assessing and tracking students’ problem solving performances in anchored learning environments

The purpose of this randomized experiment was to compare the performance of high-, average-, and low-achieving middle school students who were assessed with parallel versions of a computer-based test (CBT) or a paper-pencil test (PPT). Tests delivered in interactive, immersive environments like the CBT may have the advantage of providing teachers with diagnostic tools that can lead to instruction tailored to the needs of students at different achievement levels. To test the feasibility of CBT, students were randomly assigned to the CBT or PPT test conditions to measure what they had learned from an instructional method called enhanced anchored math instruction. Both assessment methods showed that students benefited from instruction and differentiated students by achievement status. The navigation maps generated from the CBT revealed that the low-achieving students were able to navigate the test, spent about the same amount of time solving the subproblems as the more advanced students, and made use of the learning scaffolds.

执法生态化的困境及其破解路径

执法生态化是生态学向行政法学延伸、扩展和渗透的综合性产物.具体是指执法主体在执法理念、执法机构、执法行为与执法技术等执法的各个环节都贯彻生态文明思想、遵循生态理性、坚持生态原则的指向性活动.但是,执法生态化在实践中却面临着诸多困境.当下,执法理念的生态化——树立人本精神、执法主体的生态化——依法公开信息、执法权配置的生态化——保证科学合理、执法权运行的生态化是破解执法生态化困境的四驾马车,从上述四方面着手是破解执法生态化困境的不二法门.     

面向团体用户的公共图书馆服务——针对天津地区的调研

团体用户是公共图书馆的目标用户之一,针对团体用户的需要提供信息服务是公共图书馆的重要职责.本文针时天津地区的团体用户,在时60家不同类型团体调研的基础上,分析了影响团体用户服务需求与服务选择的各种因素和团体用户对公共图书馆作用的认知和期待,提出团体用户已经成为一个亟待开发的用户群体,他们对公共图书馆服务有不可忽视的需求,对图书馆作用的认识和期待正在不断提升.公共图书馆应关注他们的需要,调整和完善服务项目及方式,并将滨海新区开发开放纳入到图书馆服务的视野中,使图书馆为团体用户的服务满足滨海新区建设的要求.     

闽江口湿地互花米草地上生物量的月动态特征

利用2008年3月～10月闽江口湿地互花米草地上生物量等群落特征的调查资料,分析其地上生物量、地上生物量的绝对生长速率和相对生长速率、株高、密度的月动态特征,同时利用spss软件对生物量、株高、密度作相关分析.结果表明:①地上生物量在7月中旬达到最大值,为2658.9g/m2,其月变化经历了一个"增加-减小-缓慢增加"的过程;②绝对生长速率在5月～6月达到最大值,为32.48 g/(m~2·d),之后波动变化,在7月～8月出现负值;③相对生长速率在4月～5月达到最大值,为0.043 g/(g·d),也在7月～8月出现负值;④株高在7月份达到最高点,平均株高达219cm;密度在5月份达到最高点,为208株/m~2;⑤株高与地上生物量呈极显著正相关,而平均密度与地上生物量、平均株高则无显著相关.     

赛前强化训练对短跨项目运动员T淋巴细胞和唾液SIgA的影响

通过对广东省田径队参加“2 0 0 0年全国田径锦标赛”优秀短跨项目运动员 4周大强度训练和比赛的跟踪调查 ,观察大强度长时间训练和比赛对其机体免疫机能的影响。结果表明 :长时间大强度训练使T淋巴系统功能降低 ,整个训练期CD4+ /CD8+ 值低于正常值 ,呈非常显著性差异 (P <0 .0 1) ;CD4+ 百分含量显著下降 (P <0 .0 5 ) ,但CD8+ 百分含量变化不大。经过调整和比赛后 ,所有指标均有升高趋势 ,但没有统计学意义。整个训练和比赛中 ,分泌型免疫球蛋白SIgA呈现对抗原刺激后的增加 ,训练后有显著性差异 (P <0 .0 5 )。结果提示 :高水平田径短跨项目运动员赛前大强度长时间训练会导致机体T淋巴细胞免疫系统功能下降 ,但是粘膜免疫系统功能在外界抗原刺激下有所升高 ,且训练后SIgA的变化与CD4+ 及CD4+ /CD8+ 值显著相关。因此 ,利用两者的变化可监测田径短跨项目运动员机体免疫系统功能的变化

The Representation of Altruistic and Egoistic Motivations in Children’s TV Programming

A content analysis of children’s television examined the frequency with which behaviors were (a) driven by altruistic versus egoistic motivations, (b) performed by affable/surly characters, (c) rewarded/punished, and (d) present in content popular among different age groups (2–5, 6–11, and 12–17 years old). We found that portrayal patterns stressed the importance of egoistic motivations (particularly competence, autonomy, and relatedness) for older children. The findings are interpreted in line with logic underlying the model of intuitive morality and exemplars (MIME; Tamborini, 2013), suggesting that media representations can influence the motivations of their viewers.
