  1. ArizMATYC Fall 2011 Avoiding Curriculum Whiplash

  2. Objectives • Discuss the “typical” order of topics for MAT121 • Discuss the order I have been using for a few semesters. • Discuss some results.

  3. Typical Topic Order for MAT121 Radical Expression & Equations Introduction to Radicals Rational Exponents Simplifying Radicals Adding & Subtracting Radicals Multiplying Radicals Dividing Radicals (Rationalizing Denominators Solving Radical Equations Complex Numbers Quadratic Functions Solve Quad Equations by Square Root Method Solve Quad Equations by Completing the Square Solve Quads by Quadratic Formula Solve Quadratics in Form Graph Quadratics by Using Transformations Vertex Formula (Graphing & Applications) Exponential & Logarithmic Functions Introduce Exponential Functions Introduce Logarithmic Functions Use Logarithm Rules Review – Multiplying Polynomials Factoring & Quadratics Common Factor Factor by Grouping Factoring Trinomials Factoring Special Products Solving Quadratic Equations by Factoring Applications to Quadratic Equations Rational Expressions & Equations Simplify Rational Expressions & Domain Multiply & Divide Rational Expressions Add Like Rational Expressions & LCD Add Unlike Rational Expressions Solve Rational Equations Applications to Rational Equations.

  4. New Topic Order for MAT121 Solving Equations Solving Quadratic Equations by Factoring Solve Quad Equations by Square Root Method Solve Quads by Quadratic Formula Solve Quad Equations by Completing the Square Solve Rational Equations Solving Radical Equations Solve Quadratics in Form Applications Applications to Quadratic Equations Applications to Rational Equations. Graphing Quadratic Graph Quadratics by Using Transformations Vertex Formula (Graphing & Applications) Exponential & Logarithmic Functions Introduce Exponential Functions Introduce Logarithmic Functions Use Logarithm Rules Review – Multiplying Polynomials Factoring Common Factor Factor by Grouping Factoring Special Products Factoring Trinomials Rational Expressions Simplify & Multiply Rational Expressions Divide Rational Expressions & LCD Add Rational Expressions Radical Expression & Equations Introduction to Radicals Rational Exponents Simplifying & Add/Sub Radicals Multiplying & Divide Radicals Complex Numbers Very Important Expression (Quad Formula

  5. Anecdotally Students have a better grasp on solving equations. What has this new order meant? Don’t really have much data yet to compare pass rates and such Class Grades Fall 2011 F2F Median 79.5 Average 80.2 Std Dev 12.1 22 students Class Grades Fall 2011 Hybrid Median 90.5 Average 88.2 Std Dev 10.3 12 students
