Nanoworld webquests with peer-review
نویسندگان
چکیده
We discuss two developments in our program [1] to develop web-content for individual teachers in web-connected classrooms, as a developing force in modernization of both pedagogy and content. The first involves development of web-based specimen explorers capable of supporting scripted, open-ended, and classroom-structured nanoworld exploration. The second involves use of "journal management software" to streamline anonymous classroom peer review of individual student observation reports, thus giving students experience with both sides of the peer review process in topic areas relevant to their course. The web-explorers discussed here involve a Mathematica-based applet [2] capable of only simple geometric rendering. It is freely available, and its floating point geometry allows one to put together specimens with structure ranging over "powers-of-ten" size scales [3]. Platforms that incorporate nanoworld contrast mechanisms and physics remain scarce.

متن کاملNanopipette exploring nanoworld
Nanopipettes, with tip orifices on the order of tens to hundreds of nanometers, have been utilized in the fields of analytical chemistry and nanophysiology. Nanopipettes make nanofabrication possible at liquid/solid interfaces. Moreover, they are utilized in time-resolved measurements and for imaging biological materials, e.g., living cells, by using techniques such as scanning ion-conductance ...
