This book is combined with a Web site to allow the reader to acquire the basic concepts of item response theory without becoming enmeshed in the underlying mathematical and computational complexities. The first edition, with its accompanying software, was designed to give the reader access to the basic concepts of item response theory without…

Computer Algebra Systems (CAS) can be used to help understand the behavior of cubics and other families of curves. The analysis of the parameters associated with a family of curves can give insight into the behavior of the family and can be used within the context of a mathematical model to determine a policy for the implementation of the model in…

The concepts of quantitative and structural change are considered from a multivariate perspective. A hybrid of these two types of change, quantistructural change, is described. (CS)

Though unshelved books are a problem in every library, little systematic effort has been made to design an optimal solution. Presented here is a mathematical model that attempts to approach such a solution. (2 references) (Author/DH)

How far does the back end of a bus swing out as the driver makes a turn at an intersection?'' is the problem discussed. (MM)

A mathematical definition of an information network is constructed with the purpose of developing a theory useful in answering practical questions concerning information transfer. (10 references) (Author)

System for measuring updating process in conjunction with psychological and environmental effects. (IR)

Investigates implications for finite and known item populations for classical test theory, and the alpha coefficient among items in paper-and-pencil testing. (Author/AG)
