Yet the non-teaching perspective of the article did not keep Kelvin, a long-time school teacher and current university teacher, from reflecting on the article in terms of its educational relevance. As we mentioned already, Kelvin was attracted to the article because of his own concerns about character development in students—how do they acquire moral beliefs and commitments, and how should he help them in doing so? Kelvin did not really expect to find an answer to the second of these questions, given the "observation" orientation of the authors. He did hope to find an answer to the first, although even here he also expected that to make allowances for the fact that research interviews are not usually identical to classroom situations. Children might respond differently when interviewed individually by a researcher, compared to how they might respond to a teacher in class. Or perhaps not. So in reflecting on the article, Kelvin had to note the context and purposes of Saltzstein's study, and to remind himself that once a teacher went beyond simply observing children to intervening on their behalf, the teacher might be led to different conclusions about children’s moral development. But in spite of these cautions—or maybe because of them—Kelvin found much food for thought in the article related to teaching.

Example #2: learning disability as a misleading label

In 2006, Ray McDermott, Shelley Goldman, and Hervé Varenne published an article that discussed the use of disability categories in education. The article attracted Kelvin’s attention because he had been concerned for a long time about the ambiguities of disability categories (see [link] Chapter 5 of this book) as well as about their potential for stigmatizing individuals. He expected the article to document additional problems with labeling when a student is from a non-white ethnic group. Kelvin’s expectation was fulfilled partially, but he was surprised also to encounter an additional and tougher message in the article. Here is how the study began:

Since about 1850…classifying human beings by mental ability, accurately or not, has been a politically rewarded activity. Those with power have placed others, usually the downtrodden, into ability and disposition groups that they cannot escape… People who live together in a culture must struggle constantly with the constraints…of systems of classification and interpretation used in the culture. Kelvin had a mixed reaction to this opening. In one way it seemed to say something familiar—that classification systems (such as categories for disabilities) may create problems for individuals. But the tone of the paragraph sounded more severely critical than Kelvin had expected: it was saying that power governed all classifications, implying that misclassifications may be widespread or even universal.

Kelvin’s initial hunch was therefore that the article would express a radically critical view of disability classifications—particularly as they affect the “downtrodden”, which presumably included children from minority ethnic groups. His expectation proved correct as the authors explained their point of view, which they called a cultural approach to understanding disability. Using learning disabilities (LD) as an example, here is how they explained their position:

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
