Using an interactive platform to recognize the intersection of social and spatial inequalities     

Lisa Poling  Travis Weiland 《Teaching Statistics》2020,42(3):108-116

With the creation of interactive tasks that allow students to explore spatial ways of knowing in conjunction with their other ways of knowing the world, we create a space where students can make sense of information as they organize these new ideas into their already existing schema. Through the use of a Common Online Data Analysis Platform (CODAP) and data from Public Use Microdata Areas (PUMA), students can explore the communities in which they live and work, critically examining opportunities and challenges within a defined space.  相似文献   

An alternative to fortified schools: Using crime prevention through environmental design (CPTED) to balance student safety and psychological well-being     

Daniel Lamoreaux  Michael L. Sulkowski 《Psychology in the schools》2020,57(1):152-165

In response to tragic school shootings, heightened attention has been devoted to making schools safer through the implementation of security features. However, excessive security measures have a negative impact on school climate, student functioning, and academic achievement. Therefore, there is a critical need to design schools that are safe and secure, yet also welcoming and comfortable. As a promising approach in this regard, crime prevention through environmental design (CPTED) is an architectural philosophy that aims to deter criminal or antisocial behavior through environmental design, and it includes a focus on natural surveillance, access control, and territorial reinforcement. This review discusses pertinent effects of the school environment on student outcomes, extant research on the impact of visible security measures, the relationship between students’ perceptions of safety and academic functioning, and how using CPTED could concomitantly address the physical safety and psychological comfort of students at school.  相似文献   

《反兴奋剂运动员权利规则》审思          下载免费PDF全文

裘韵 《体育科研》2020,(2):45-53

《反兴奋剂运动员权利规则》是由世界反兴奋剂机构下属的运动员委员会制定,执行委员会批准通过的首个明确规定运动员在反兴奋剂活动中权利的文件。作为运动员参与反兴奋剂活动的基础,该文件的制定与修订争议不断,多集中于文件名称、法律地位及其内容中不具有强制执行力的部分。在体育组织的干预下,起草者修改了文件的名称并澄清“这不是一份法律文件”,使该文件的意义与价值存疑。建议在日后的修订中慎重考虑文件名称的匹配性,在厘清该文件与《世界反兴奋剂条例》及国际标准关系的基础上,赋予其法律效力或给予象征性法律规则的地位,完善对受侵犯权利救济的指引,加快建立申诉处理机制。  相似文献   

Ergogenic effects of precooling with cold water immersion and ice ingestion: A meta-analysis     

Hui C. Choo  Kazunori Nosaka  Jeremiah J. Peiffer  Mohammed Ihsan  Chris R. Abbiss 《European Journal of Sport Science》2018,18(2):170-181

This review evaluated the effects of precooling via cold water immersion (CWI) and ingestion of ice slurry/slushy or crushed ice (ICE) on endurance performance measures (e.g. time-to-exhaustion and time trials) and psychophysiological parameters (core [T_core] and skin [T_skin] temperatures, whole body sweat [WBS] response, heart rate [HR], thermal sensation [TS], and perceived exertion [RPE]). Twenty-two studies were included in the meta-analysis based on the following criteria: (i) cooling was performed before exercise with ICE or CWI; (ii) exercise longer than 6?min was performed in ambient temperature ≥26°C; and (iii) crossover study design with a non-cooling passive control condition. CWI improved performance measures (weighted average effect size in Hedges’ g [95% confidence interval]?+?0.53 [0.28; 0.77]) and resulted in greater increase (ΔEX) in T_skin (+4.15 [3.1; 5.21]) during exercise, while lower peak T_core (?0.93 [?1.18; ?0.67]), WBS (?0.74 [?1.18; ?0.3]), and TS (?0.5 [?0.8; ?0.19]) were observed without concomitant changes in ΔEX-T_core (+0.19 [?0.22; 0.6]), peak T_skin (?0.67 [?1.52; 0.18]), peak HR (?0.14 [?0.38; 0.11]), and RPE (?0.14 [?0.39; 0.12]). ICE had no clear effect on performance measures (+0.2 [?0.07; 0.46]) but resulted in greater ΔEX-T_core (+1.02 [0.59; 1.45]) and ΔEX-T_skin (+0.34 [0.02; 0.67]) without concomitant changes in peak T_core (?0.1 [?0.48; 0.28]), peak T_skin (+0.1 [?0.22; 0.41]), peak HR (+0.08 [?0.19; 0.35]), WBS (?0.12 [?0.42; 0.18]), TS (?0.2 [?0.49; 0.1]), and RPE (?0.01 [?0.33; 0.31]). From both ergogenic and thermoregulatory perspectives, CWI may be more effective than ICE as a precooling treatment prior to exercise in the heat.  相似文献   

Adult stakeholder perceptions of 4th grade participation in children’s forest environmental education programming     

Ryan F. Reese 《Environmental Education Research》2018,24(8):1211-1223

An environmental education (EE) consortium located in the pacific northwest United States coalesced an external evaluation team to research its K-5 EE programming. The purpose of this article is to describe one phase of this program evaluation process including the exploration of adult stakeholder perceptions of EE programming accessed by 4th grade children. The author highlights the goals of the consortium and the context for the program evaluation, and the relevant literature addressing adult perspectives on EE is reviewed. The study framing, method, and qualitative results are reported. Findings suggest that adult stakeholders perceived positive impacts from 4th grade participation in EE, though the programming was viewed as being most beneficial to children coming from economically disadvantaged families. Implications for EE practice and research are discussed.  相似文献   

Changes in experiences with nature through the lives of environmentally committed university faculty     

Nicolette L. Cagle 《Environmental Education Research》2018,24(6):889-898

Previous work has identified time spent in nature as a child as a precursor to active care for the natural world (i.e. environmental commitment), but a paucity of data exists on what happens to environmentally committed people’s relationship to nature over time, including the time spent in nature and the quality of that experience. In addition, previous work has not more finely categorized these nature experiences, with the exception of natural history-oriented professionals. I address these gaps by conducting in-depth interviews with 12 faculty in the environment at Duke University regarding relationships with nature throughout their life. The interviews reveal that the amount of time spent in nature, and the quality of that experience, changed for this cohort over time. Moreover, these interviews revealed nuanced aspects of relationships with nature that changed with life stage, complementing that work which was conducted on natural history-oriented professionals. This work suggests that more research is needed on the changing relationship with nature among adults and environmental educators.  相似文献   

Fostering changes in attitude,knowledge and behavior: demographic variation in environmental education effects     

Tina Braun  Richard Cottrell  Paul Dierkes 《Environmental Education Research》2018,24(6):899-920

This study employs a uniquely multi-factorial, large-scale design to investigate baseline differences and the effects of a singular outdoor educational program on environmental attitudes, knowledge and behavior among primary and secondary school students educated in four different countries. Statistical modelling approaches employed country of residence, age, nationality, sampling year, gender and urban/ rural habitation as predictor variables. Baseline scores were explained by a number of predictors but country of residence and rural-urban differences appeared as the most consistent explanatory variable for positive changes in attitude, knowledge and behavior. Given the nexus of political, social, natural and cultural data contained within the residence variable, we discuss the complex web of drivers that may influence environmental literacy and environmentally responsible behavior. Spatial variation in the value of outdoor education programs is also discussed.  相似文献   

Can young students think systemically about the environment? The case of pollution     

Ifigenia Iliopoulou 《Education 3-13》2018,46(3):362-377

This paper reports on the thoughts 6-year-olds and 9-year-olds have related to the serious issue of air and sea pollution. More specifically, twenty seven 6-year-olds and thirty 9-year-olds attending two state schools in Volos, a small provincial town in Greece participated in the research which assessed the students’ competence to think systemically about dealing with pollution. The study sheds light on whether students are able to identify interrelations between the components of pollution, and clarifies the mental models they hold. Data was collected through drawings and interviews, subsequent analysis of which indicates that students appeared to hold two mental models related to pollution; pollution is connected both spatially and temporally with visible pollutants; and, pollution is connected indirectly with invisible pollutants. The students seemed to exhibit a kind of systemic thinking, which was done unconsciously to a certain degree. Thus it is a challenge for education to enhance students’ systemic thinking in an attempt to bring it to a more conscious level, which will assist them to reconstruct their mental models of pollution.  相似文献
