Core Curriculum: State Criteria

Perspectives (The following reflect the state-mandated perspectives taught in this course.):

  • Establish broad and multiple perspectives on the individual in relationship to the larger society and world in which he/she lives, and to understand the responsibilities of living in a culturally and ethnically diversified world.
  • Develop a capacity to use knowledge of how technology and science affect their lives.
  • Use logical reasoning in problem solving.
  • Integrate knowledge and understand the interrelationships of the scholarly disciplines.

Exemplary Objectives (The following reflect the state-mandated exemplary objectives taught in this course.):

Mathematics: The objective of the mathematics component of the core curriculum is to develop a quantitatively literate college graduate. Every college graduate should be able to apply basic mathematical tools in the solution of real-world problems.

  • To apply arithmetic, algebraic, geometric, higher-order thinking and statistical methods to modeling and solving real-world situations.
  • To represent and evaluate basic mathematical information verbally, numerically, graphically, and symbolically.
  • To expand mathematical reasoning skills and formal logic to develop convincing mathematical arguments.
  • To use appropriate technology to enhance mathematical thinking and understand and to solve mathematical problems and judge reasonableness of the results.
  • To interpret mathematical models such as formulas, graphs, tables and schematics, and draw inferences from them.
  • To develop the limitations of mathematical and statistical models.
  • To develop the view that mathematics is an evolving discipline interrelated with human culture, and understand its connections to other disciplines.
