Helping Students Discover Total Internal Reflection part of Examples
Students learn the basic relationship of Snell's Law, practice applying it to a situation, then are given another situation where it "doesn't work."??? This situation turns out to be one in which total internal reflection occurs. Students are then shown what happens with classroom apparatus.
The Evolution of Pearson’s 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.
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.
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.
Psychic test part of Examples
Show relative frequency converging to true probability by testing the psychic ability of your students.
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.
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.
Rutherford's Model of the Atom part of Examples
Students are asked think-pair-share questions to predict the interaction of alpha particles fired toward the nucleus of an atom. An online applet is used to illustrate the interaction and test students' ideas for the causes of the interaction. This activity uses a resource in the comPADRE partner collection.
