In this video segment from TV411, figure skaters compute their average daily practice time.

This learning video continues the theme of an early BLOSSOMS lesson, Flaws of Averages, using new examples—including how all the children from Lake Wobegon can be above average, as well as the Friendship Paradox. As mentioned in the original module, averages are often worthwhile representations of a set of data by a single descriptive number. The objective of this module, once again, is to simply point out a few pitfalls that could arise if one is not attentive to details when calculating and interpreting averages. Most students at any level in high school can understand the concept of the flaws of averages presented here. The essential prerequisite knowledge for this video lesson is the ability to calculate an average from a set of numbers. Materials needed include: pen and paper for the students; a blackboard or equivalent; and coins (one per student) or something similar that students can repeatedly use to create a random event with equal chances of the two outcomes (e.g. flipping a fair coin). The coins or something similar are recommended for one of the classroom activities, which will demonstrate the idea of regression toward the mean. Another activity will have the students create groups to show how the average number of friends of friends is greater than or equal to the average number of friends in a group, which is known as The Friendship Paradox. The lesson is designed for a typical 50-minute class session.

In this new video we look at the basics of bacteria. We look at their classifications, sizes, shapes and how they reproduce. This video is intended to be a primer on bacteria. We will go into more details as we progress in this series.

True love has the right ratio. In this humorous animation, the number of words spoken by each partner predicts whether a date goes well or horribly. What do you do when someone asks if you listen to country music backwards, but won't let you get a word in edgewise?

This video lecture presents the basic definitions of assets, liabilities and equity with simple examples. It also explains the concept of accounting equation with examples.

There are many reasons to keep your money in a bank or credit union. The October 2020 issue of Page One Economics®: Focus on Finance describes what banks, credit unions, and online banks are and outlines things to consider when choosing where to have an account and what type of account to have.

These short videos explain bankruptcy a legal process that provides relief to many individuals who can no longer pay all of their debts.

Payday and title lenders, pawn shops, check-cashing services and prepaid cards can be convenient and valuable financial services, similar to those offered by traditional providers of such services—banks and credit unions. What are the costs and benefits of using alternative financial services, as well as of going to a bank or credit union?

This art history video looks at "The Painting Techniques of Barnett Newman: Vir Heroicus Sublimis" Abstract Expressionist New York, The Museum of Modern Art, October 3, 2--April 11, 2011. Filmed by Plowshares Media; Music by Chris Parrello, Ian Young, Kevin Thomas, Ziv Ravitz.

This unit introduces basic computing concepts and terminology. It identifies common elements of computers, both in terms of hardware and software and provides information on selecting a computer by discussing the range of computer types, from desktops to laptops to servers. Finally, it provides a history of the development of computing and healthcare information systems over time.

This video goes through four examples on subtracting integers. To subtract integers remember to change it into an addition problem. The first number plus the opposite of the second number.

A Beautiful Mind won the Academy Award for best picture in 2001 and it chronicles the life of John Nash who is noted for his pioneering work on general equilibrium theory. This scene is a great way to discuss self-interest and contrast it with the social optimum. Nash's work has augmented Adam Smith's "invisible hand" theory by extending how self-interest is modeled. This scene is must viewing even though the scene itself contains flawed economics (explaining why the scene is NOT a Nash equilibrium helps students learn the concept in greater depth).

This short video and interactive assessment activity is designed to teach third graders about before and after problems.

Experienced Registered Reports editors and reviewers come together to discuss the format and best practices for handling submissions. The panelists also share insights into what editors are looking for from reviewers as well as practical guidelines for writing a Registered Report. ABOUT THE PANELISTS: Chris Chambers | Chris is a professor of cognitive neuroscience at Cardiff University, Chair of the Registered Reports Committee supported by the Center for Open Science, and one of the founders of Registered Reports. He has helped establish the Registered Reports format for over a dozen journals. Anastasia Kiyonaga | Anastasia is a cognitive neuroscientist who uses converging behavioral, brain stimulation, and neuroimaging methods to probe memory and attention processes. She is currently a postdoctoral researcher with Mark D'Esposito in the Helen Wills Neuroscience Institute at the University of California, Berkeley. Before coming to Berkeley, she received her Ph.D. with Tobias Egner in the Duke Center for Cognitive Neuroscience. She will be an Assistant Professor in the Department of Cognitive Science at UC San Diego starting January, 2020. Jason Scimeca | Jason is a cognitive neuroscientist at UC Berkeley. His research investigates the neural systems that support high-level cognitive processes such as executive function, working memory, and the flexible control of behavior. He completed his Ph.D. at Brown University with David Badre and is currently a postdoctoral researcher in Mark D'Esposito's Cognitive Neuroscience Lab. Moderated by David Mellor, Director of Policy Initiatives for the Center for Open Science.
