Effect of Initial Value on Graph of Exponential Function (C < 0) part of Interactive Lectures:Examples

This classroom activity presents College Algebra students with a ConcepTest and a Question of the Day activity concerning the effect of the initial value, C, on the y-intercept and position of an exponential function where C<0 and k is an arbitrarily fixed value in f(x)=Ce^(kx

Effect of Initial Value on Graph of Exponential Function (C>0) part of Interactive Lectures:Examples

This classroom activity presents College Algebra students with a ConcepTest and a Question of the Day activity concerning the effect of the initial value, C, on the y-intercept and position of an exponential function where C>0 and k is an arbitrarily fixed value in f(x)=Ce^(kx).

Effect of Proportionality Constant on Exponential Graph (k < 0) part of Interactive Lectures:Examples

This classroom activity presents College Algebra students with a ConcepTest and a Question of the Day activity concerning the effect of the proportionality constant, k, on the y-intercept and position of an exponential graph where k<0 and C is an arbitrarily fixed value in f(x)=Ce^(kx).

Effect of Coefficient of x^2 on Parabola Shape part of Interactive Lectures:Examples

This classroom activity presents College Algebra students with a ConcepTest, a Question of the Day, and a Write-pair-share activity concerning the effect of the coefficient of x^2 on the shape of a parabola where b and c are arbitrarily fixed values in f(x)=ax^2+bx+c.

Effect of Coefficient of x^0 on Parabola Vertex part of Interactive Lectures:Examples

This classroom activity presents College Algebra students with a ConcepTest, a Question of the Day, and a Write-pair-share activity concerning the effect of the coefficient of x^0 (i.e., the constant, c) on the vertex of a parabola where a and b are arbitrarily fixed values in f(x)=ax^2+bx+c.

Effect of Coefficient of x on Parabola Vertex (b < 0) part of Interactive Lectures:Examples

This classroom activity presents College Algebra students with a ConcepTest, a Question of the Day, and a Write-pair-share activity concerning the effect of the coefficient of x on the vertex of a parabola where a>0, b<0 and a and c are fixed values in f(x)=ax^2+bx+c.

U.S. Population Growth: What Does the Future Hold? part of Interactive Lectures:Examples

College Algebra or Liberal Arts math students are presented with a ConcepTest, a Question of the Day and a write-pair-share activity involving U.S. population growth. The results are quite revealing and show that while students may have learned how to perform the necessary calculations, their conceptual understanding concerning exponential growth may remain faulty. Student knowledge (or lack thereof) of the size of our population and its annual growth rate may also be surprising.

How Much Work is Required: Intuition vs. Mathematical Calculation part of Interactive Lectures:Examples

This classroom activity presents Calculus II students with some Flash tutorials involving work and pumping liquids and a simple question concerning the amount of work involved in pumping water out of two full containers having the same shape and size but different spatial orientations.

Question of the Day: Ocean Waves #1 part of Interactive Lectures:Question of the Day

Sketch a simple diagram of an ocean wave and label its crest, trough, and wavelength. You are in a boat and you have a stop watch. How do you measure the period of the ocean waves passing beneath you? What ...

Question of the Day: The Structure of the Earth part of Interactive Lectures:Question of the Day

On the cross-section diagram below, label: Crust. Mantle. Lithosphere. Asthenosphere. The depth to the boundaries between each of the above specified layers. The direction of lithospheric motion. Where you would ...
