Describes a precise yet simple method for computing eigenvalues and eigenvectors of a symmetric matrix useful in teaching quantum mechanics. (SK)

This paper describes a theoretical perspective in which teacher performance and classroom procedures in technology-based settings can be observed and compared. The paper uses as an example the Systems Thinking and Curriculum Innovation Network (STACIN) Project, which implements a simulation-modeling software package as an analytic problem solving…

Research was conducted that initially focused on identifying and synthesizing the large number of previously identified vocational special needs teacher competencies into an educational model.
