Changing attitudes and emotions toward coyotes with experiential education

ABSTRACT

An experiential education program was designed to target risk perceptions and preventative measures that make people feel comfortable in human-coyote interactions. The research was conducted in a Canadian national park where a coyote caused a human fatality in 2009. Based on previous research, we explored the effects of an experience-based coyote education program on people's (a) attitudes toward, (b) fear of, (c) likelihood of, and (d) control over coming into contact with coyotes. A pre-post-test experiment (n = 150; 96% completion rate) was conducted. The experiential education approach to wildlife safety and coexistence communication had a significant positive effect on people's attitudes, significantly decreased their sense of fear toward coyotes, significantly decreased their sense of likelihood, and increased their sense of control in human-coyote interactions.     

Nanoparticle image velocimetry at topologically structured surfaces

Nanoparticle image velocimetry (nano-PIV), based on total internal reflection fluorescent microscopy, is very useful to investigate fluid flows within ∼100 nm from a surface; but so far it has only been applied to flow over smooth surfaces. Here we show that it can also be applied to flow over a topologically structured surface, provided that the surface structures can be carefully configured not to disrupt the evanescent-wave illumination. We apply nano-PIV to quantify the flow velocity distribution over a polydimethylsiloxane surface, with a periodic gratinglike structure (with 215 nm height and 2 μm period) fabricated using our customized multilevel lithography method. The measured tracer displacement data are in good agreement with the computed theoretical values. These results demonstrate new possibilities to study the interactions between fluid flow and topologically structured surfaces.     

Utilizing Adventure Education Within the Model of Moral Action

Character development has long been an assumed if not easily observed goal of physical activity. Shields and Bredemeier(1995, 2001) proposed a structural developmental model of moral action strongly based on the work of Rest (1984, 1994) along with the significant contributions of Piaget (1923), Kohlbcrg (1981, 1984), and Haan (Haan, Aerts, & Conper, 1985). Adventure education is an experientially based approach that utilizes cooperative physical activities to foster self esteem, trust, communication skills, self awareness, confidence, and the ability to problem solve (Bissnn, 1999: Prouty, 1999). The purpose of this paper is lo explore how adventure-based intervention strategies correspond with the theoretical tenets and implementation guidelines of the model of moral action. The major tenets of the model of tnoral action (Shields & Bredemeier, 1995, 2001) and adventure education are discussed. The extent to which adventure education may act as a conduit for the moral education strategies forwarded by the model of moral action is discussed.     

建立在探索基础上的中小学数学教育回顾与展望

过去几十年中小学数学教育研究的主要进展表现在：数学教育改革，社会交流研究，课程发展研究等方面，数学教育研究应该将教育实践活动，课程开发，数学学科教育理论研究3者结合起来，当前，中小学数学课堂改革主要是：接受学生是在和思维材料相互作用的过程中建构数学知识的观念，以及课程改革、技术改革和数学语言改革等方面。
