Standardized test outcomes for students engaged in inquiry-based science curricula in the context of urban reform
(Wiley Subscription Services, Inc., A Wiley Company, 2008-10)
Considerable effort has been made over the past decade to address the needs of learners in large urban districts through scaleable reform initiatives. We examine the effects of a multifaceted scaling reform that focuses ...
Search for cyclotron resonance in cells in vitro
(Wiley Subscription Services, Inc., A Wiley Company, 1989)
There are a number of reports of the plasma membrane transport of Ca 2+ in biological systems being enhanced by low frequency electromagnetic fields (EMF), including reports that the enhancement involves a resonance-type ...
An Approximate Test for Homogeneity of Correlated Correlation Coefficients
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-03)
This paper develops and evaluates an approximate procedure for testing homogeneity of an arbitrary subset of correlation coefficients among variables measured on the same set of individuals. The sample may have some missing ...
Extrapolating human probability judgment
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-03)
We advance a model of human probability judgment and apply it to the design of an extrapolation algorithm. Such an algorithm examines a person's judgment about the likelihood of various statements and is then able to predict ...
A linear-time algorithm for constructing a circular visibility diagram
(Springer-Verlag; Springer-Verlag New York Inc., 1995-09)
To computer circular visibility inside a simple polygon, circular arcs that emanate from a given interior point are classified with respect to the edges of the polygon they first intersect. Representing these sets of ...
Pre- and post-planned evaluation: Which is preferable?
(Elsevier, 1978)
This paper compares the advantages and disadvantages of the "pre-planned" and "post-planned" approaches to evaluating program effectiveness. These evaluative approaches are compared along a number of dimensions which ...
Average Case Analysis of Gosper’s Algorithm for aClass of Urn Model Inputs
(Springer-Verlag; Springer, 2005-09)
In this paper we perform an asymptotic average case analysis of some of the most important steps of Gosper’s algorithm for indefinite summation of hypergeometric terms. The space of input functions of the algorithm is ...
Discipline‐centered post‐secondary science education research: Distinctive targets, challenges and opportunities
(Wiley Periodicals, Inc.Grune and Stratton, 2014-08)
The impact of an integrated approach to science and literacy in elementary school classrooms
(Wiley Subscription Services, Inc., A Wiley Company, 2012-05)
This study investigates the efficacy of an integrated science and literacy approach at the upper‐elementary level. Teachers in 94 fourth grade classrooms in one Southern state participated. Half of the teachers taught the ...
