A variety of examples are given from different areas of biology to illustrate the general applicability of matrix algebra to discrete models. These models of biological systems are concerned with relations between processes occurring in discrete time intervals. Diffusion, ecosystems, and different types of cells are modeled. (KR/Author)

This paper describes a study that investigated the communication network efficiency and network efficiency stability of four urban high schools, using a sociometric questionnaire and a computer-developed communication matrix. Working hypothesis for the study was that schools with fewer staff members would have more efficient and more stable…

Constructing a matrix model not only offers the teacher a theoretical and practical method for organizing his own knowledge about a topic, but provides a vehicle for the student to cope with contemporary knowledge explosion in a realistic and sophisticated manner. (Author)

This unit, which looks at applications of linear algebra to population studies, is designed to help pupils: (1) understand an application of matrix algebra to the study of populations; (2) see how knowledge of eigen values and eigen vectors is useful in studying powers of matrices; and (3) be briefly exposed to some difficult but interesting…

This resource guide is designed to provide the reader with information about work experience programs in Rhode Island and other states. The first section consists of a prototypic model (which was developed in cooperation with educators and other personnel concerned with work experience programs) for making work experience-based vocational…

Classroom activities for directing student inquiry into the role of the individual in the future are provided in this text. Activities are presented within a framework of respect for and understanding of the past and the present. A matrix for the study of the individual as a whole person is presented. The matrix is devised along the present, past,…

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. The model contained a matrix that organized all these competencies into twelve domains of four performance phases each. The Competency Matrix was the…

This report describes an Indiana project to develop occupational matrices in six vocational service areas--agribusiness, business and office, health, home economics, marketing and distribution, and trades and industries. (These matrices cluster industry-verified job titles in an occupational field on the basis of task commonality.) These…
