Magma Viscosity Demos part of 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.
Using an Applet to Demonstrate a Sampling Distribution part of Examples
Introducing sampling distribution through cooperative learning among students using a group activity. Afterwards, use the sampling distribution applet to illustrate.
Using an Applet to Demonstrate Sampling Distributions of Regression Coefficients part of Examples
This applet simulates a linear regression plot and the corresponding intercept and slope histograms. The program allows the user to change settings such as slope, standard deviation, sample size, and more.
Count the Fs: Why a Sample instead of a Census? part of Examples
This interactive lecture activity motivates the need for sampling. "Why sample, why not just take a census?" Under time pressure, students count the number of times the letter F appears in a paragraph. The activity demonstrates that a census, even when it is easy to take, may not give accurate information. Under the time pressure measurement errors are more frequently made in the census rather than in a small sample.
Psychic test part of Examples
Show relative frequency converging to true probability by testing the psychic ability of your students.
The Evolution of Pearsons Correlation Coefficient/Exploring Relationships between Two Quantitative Variables part of Examples
The evolution of ideas is often ignored in the teaching of statistics. It is important to show students how definitions and formulas evolve. This activity describes a fairly straightforward activity of how measures of association can evolve.
Using an Applet to Demonstrate the Sampling Distribution of an F-statistic part of Examples
This visualization activity combines student data collection with the use of an applet to enhance the understanding of the distributions of mean square treatment (MST), mean square error (MSE) as well as their ratio, an F-distribution. Students will see theoretical distributions of the mean square treatment, mean square error and their ratio and how they compare to the histograms generated by the simulated data.
Learning to Think about Gravity: Newtons's Theory part of Examples
The purpose of this exercise is to learn how to think about gravity, learn about scientific methodology, and transition from the Aristotelian to the Newtonian understanding of gravity.
Will the egg break? part of Examples
This is a discrepant event that can be used to help students understand applications of the momentum-impulse theorem. Students are first asked to predict and hypothesize what will happen when an egg is thrown into ...
Modeling emf, Potential Difference, and Internal Resistance part of Examples
Through class discussion and think-pair-share questions, this activity helps students come to understand the difference between emf and potential difference in electrical circuits. These concepts are broached within the context of internal resistance of batteries.
