A New Mechanism for Transfer Between Conceptual Domains in Scientific Discovery and Education 总被引:1,自引:0,他引:1
Confronted with problems or situations that do not yield toknown theories and world views, scientists and students are alike. Theyare rarely able to directly build a model or a theory thereof. Rather,they must find ways to make sense of the circumstances using theircurrent knowledge and adjusting what is recognized in the process. Thisway of thinking, using past ways of perceiving the physical world tobuild new ones does not follow a logical path and cannot be described astheory revision. Likewise, in many situations it is awkward, indeedoften impossible, to resort to analogical reasoning to account for it.This paper presents a new mechanism, called `tunnel effect', that mayexplain, in part, how scientists and students reason while constructinga new conceptual domain. `Tunnel effect' is also contrasted withanalogical reasoning. 相似文献

1 Introduction1 1.1 About Hearing Mechanisms The hearing function in human beings is something very specific and difficult to understand because it uses the brain highest functions. Basically, we can say (figure 1) that several stages are involved [1]: It is not easy to give a unique interpretation to each one of these stages, as most of the involved processes overlap at all levels. Nevertheless, as a brief summary, let us assume that [2]: l The ear transmits the air vibrations and transfor… 相似文献

Summary The surface of the mesothelial peritoneal cells (Rat) show with electron microscope very thin pseudopods, 0.6–0.8 µ by 0.04–0.045 µ, separated by 0.1–0.3 µ spacings, and different from vibratile cilia, but similar to the submicroscopic pseudopods of alveolar or endothelial cells. 相似文献

A great variation was observed in the amount of soluble GFA depending on the brain area. Large amounts were found in the chiasma and in the pons whereas the cortical grey matter was poor. It is suggested that soluble GFA represents a potentiality of defense of the nervous tissue. 相似文献
