become “mutually dependent” so that advancement is done as acohesive unit with each member making contributions to the group (shared responsibility). Learning communities have some key parts of the successful Treisman’s Model.10 In theearly 1980’s Uri Treisman created programs that enlisted African-American students to excel inmathematics rather than a program created solely to help them evade failure. Like LCs,Treisman’s emphasis is on collaborative learning among the students through the use of “smallgroup teaching methods.” Students are not just expected to be remediated, but expectations areraised based on what Treiman observed to be the strength of some groups of students on hiscampus: their ability to merge academic and social lives

The 10 Gb/s NRZ optical signal is launched into 3 spans of Dispersion-Shifted singlemode fiber, each 50 Km in length. The fiber loss is recovered by 980-nm pumped EDFA beforeeach span and after the third span. The optical signal is passed through a raised-cosine filter anddetected by a

backscatteredlight are very important in a detection system.2. Theory of reflectance optical detection systemThe physical requirement necessary for an optical system in order to detect multiple numbers ofchromopores is to have light sources of specific wavelength with different absoptivity pattern.The light attenuation between the source and the detector can be written as follows: ⎛I ⎞ − log10 ⎜ out ⎟ = ODλ ⎜I ⎟ (1) ⎝ in ⎠where I in is the incident light, I out is the detected light, and ODλ is the optical density forwavelength λ . Optical density is a function of absorption ( Aλ ) and scattering ( S λ

This is that the experiencesdesigned by adults – and particularly to be credible to adults – to teach children were failing.Further, they were failing because these experiences assumed that the child’s experience would bethe same as the adult’s experience. As one might assume, this is a liberating idea for professional educators. Of course likemany liberating ideas, the liberation soon began to resemble anarchy. To get an idea of how thismight have looked in the 1920’s, one can view the play or movie Auntie Mame. The title characteris left to raise her nephew and chooses several avante garde
