Activities involving estimation of the number of objects in a configuration can motivate students to consider parametric models. (SD)

The author advocates changing the traditional approach to mechanics from emphasis on the formulation of Newton's Laws to discussion of the foundations of mechanics and Mach's formulation. (SD)

The author outlines seven types of learning and teaching, and briefly discusses related literature on learning theories. He provides examples, and discusses teaching hierarchies. (SD)

Programs in applied mathematics have been developed with emphasis on application of mathematics to business, economics, and planning. (SD)

The pros and cons of various grading systems used in statistics courses for social science students are discussed. The continuous grading scheme uses workbooks, individual projects, and other activities. (SD)

A detailed syllabus and discussion of the philosophy and procedures of a mathematics course for teachers of other subjects are provided. (SD)

Use of the computer programs provided here in APL programming language can help students understand computational algorithms. (SD)

The philosophy behind the Nuffield Mathematics Project, the process of curriculum development, and evaluation of the project are discussed. (SD)

A criterion for development of syllabi for mathematics courses is discussed. This criterion is based on the biogenetic law that individuals develop through all the stages of the development of the species. (SD)
