The purpose of the study was to examine what scientists studying to become teachers know about the nature of science (NOS) before, during and after a course focused on NOS. The 16 scientists had an average of 9.7 years of work experience. The course was structured to teach knowledge about the aspects of NOS, demonstrate effective methods of…

I profile here a prospective method for assessing nature of science (NOS) knowledge, as an alternative to VNOS and similar approaches. Questions about cases in contemporary news and from history probe scientific literacy in context. Scoring targets how "well informed" the analysis is, based on identifying relevant NOS information and interpreting…

This article comments on the previous article (Holburn, 2002), that argues misapplied approaches of person-centered planning can be remedied through scientific practices. It cautions against testing person-centered planning like a drug to establish its causal power and stresses person-centered planning as a way to improve the odds that change will…

This article argues that the popular, but at times, misapplied approaches of person-centered planning can be remedied through scientific practices. It discusses how planners can more effectively achieve today's aspirations for people with developmental disabilities by systematically assessing adherence to the process of person-centered planning…

This article comments on an article (Holburn, 2002), that argues misapplied approaches of personal-centered planning (PCP) can be remedied through scientific practices. It discusses the charge of frequent misapplication of PCP and its widespread adoption and use contrasted to methodological alternatives for evaluating the contribution of PCP. (CR)

This article responds to critiques of a previous article that called for using applied behavior analysis to scientifically evaluate personal-centered planning (PCP). It discusses the need to overcome evaluation obstacles such as inferring internal causation as explanatory, confusing process with outcome, and requiring full consensus on…

This paper is about the structural equation modelling of quantitative measures that are obtained from a multiple facet design. A facet is simply a set consisting of a finite number of elements. It is assumed that measures are obtained by combining each element of each facet. Methods and traits are two such facets, and a multitrait-multimethod…
