Geologic Puzzles: Morrison Formation part of Interactive Lectures:Examples
Images of faulted strata, tilted turbidites, and beach rocks bring the field into the classroom, giving students practice in doing what geoscientists do. These images are examples of geologic puzzles.

Magma Viscosity Demos part of Interactive Lectures:Examples
This is an interactive lecture where students answer questions about demonstrations shown in several movie files. They learn to connect what they have learned about molecules, phases of matter, silicate crystal structures, and igneous rock classification with magma viscosity, and to connect magma viscosity with volcano explosiveness and morphology.

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^2 on Parabola Vertex (a < 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^2 on the vertex of a parabola where a<0, b>0 and b and c are fixed values in f(x)=ax^2+bx+c.

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).

Economies of scale part of Cooperative Learning:Examples
Working in groups of three, students analyze economies of scale. Each student constructs an individual short-run ATC curve, then the three students collaborate to determine if there are economies or diseconomies of scale and to create the long run ATC.

Counting GDP part of Cooperative Learning:Examples
Working in small groups, students determine how 18 items are included in GDP (or if they are excluded.) Cards turned over one at a time encourage participation by all group members.

Constructing Phylogenetic Trees: The Whippo Story part of Interactive Lectures:Examples
An interactive lecture in which students use data on feeding habits and habitat, skeletons, and DNA sequences to draw phylogenetic trees.

Think-Pair-Share Activity for Understanding Price Controls part of Cooperative Learning:Examples
An exercise designed to facilitate understanding of the impacts of price controls on market outcomes, with a follow up exercise covering these and related concepts.

Using Note-Taking Pairs to Enhance Understanding of Difficult Concepts (such as Income and Substitution Effects) part of Cooperative Learning:Examples
A variation of the think-pair-share technique is used to reinforce understanding of the income and substitution effects associated with a price change.
