Often, the more information we have, the better decisions we're able to make. The power of data can benefit both individuals and governments. But who can be trusted with the responsibility of having all this data? Can governments collect and use it fairly and without violating our privacy? Help students think through this question and become thoughtful influencers of data policy and practice.

In this lesson, students learn that sound is energy and has the ability to do work. Students discover that sound is produced by a vibration and they observe soundwaves and how they travel through mediums. They understand that sound can be absorbed, reflected or transmitted. Through associated activities, videos and a PowerPoint presentation led by the teacher, students further their exploration of sound through discussions in order to build background knowledge.

This short video and interactive assessment activity is designed to teach fifth graders about determining the greatest quotient without calculation.

Students learn about and practice converting between fractions, decimals and percentages. Using a LEGO® MINDSTORMS® NXT robot and a touch sensor, each group inputs a fraction of its choosing. Team members convert this same fraction into a decimal, and then a percentage via hand calculations, and double check their work using the NXT robot. Then they observe the robot moving forward and record that distance. Students learn that the distance moved is a fraction of the full distance, based on the fraction that they input, so if they input ½, the robot moves half of the original distance. From this, students work backwards to compute the full distance. Groups then compete in a game in which they are challenged to move the robot as close as possible to a target distance by inputting a fraction into the NXT bot.

In an increasingly data-driven world, data and its use aren’t always all it’s cracked up to be. This course aims to address the critical lack of any or appropriate data in many areas where complex decisions need to be made.

For instance, how can you predict volcano activity when no eruptions have been recorded over a long period of time? Or how can you predict how many people will be resistant to antibiotics in a country where there is no available data at national level? Or how about estimating the time needed to evacuate people in flood risk areas?

In situations like these, expert opinions are needed to address complex decision-making problems. This course, aimed at researchers and professionals from any academic background, will show you how expert opinion can be used for uncertainty quantification in a rigorous manner.

Various techniques are used in practice. They vary from the informal and undocumented opinion of one expert to a fully documented and formal elicitation of a panel of experts, whose uncertainty assessments can be aggregated to provide support for complex decision making.

In this course you will be introduced to state-of-the-art expert judgment methods, particularly the Classical Model (CM) or Cooke’s method, which is arguably the most rigorous method for performing Structured Expert Judgment.

CM, developed at TU Delft by Roger Cooke, has been successfully applied for over 30 years in areas as diverse as climate change, disaster management, epidemiology, public and global health, ecology, aeronautics/aerospace, nuclear safety, environment and ecology, engineering and many others.

Introduction to the theory and application of large-scale dynamic programming. Markov decision processes. Dynamic programming algorithms. Simulation-based algorithms. Theory and algorithms for value function approximation. Policy search methods. Games. Applications in areas such as dynamic resource allocation, finance and queueing networks, among others.

Foundations and philosophical applications of Bayesian decision theory, game theory and theory of collective choice. Why should degrees of belief be probabilities? Is it always rational to maximize expected utility? If so, why and what is its utility? What is a solution to a game? What does a game-theoretic solution concept such as Nash equilibrium say about how rational players will, or should, act in a game? How are the values and the actions of groups, institutions and societies related to the values and actions of the individuals that constitute them?

This lesson plan looks at the major ideas in the Declaration of Independence, their origins, the Americans' key grievances against the King and Parliament, their assertion of sovereignty, and the Declaration's process of revision.

This collection uses primary sources to explore the Declaration of the Rights of Man and of the Citizen. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

In this activity students analyze a timeline and official and unofficial documents that reveal the events of the Iran-Contra Affair. This activity also models the types of questions that can help students analyze foreign policy documents from other events. The activity instructions include suggestions for how to differentiate the activity for students with different reading levels.

This video explains design of the Arecibo Message transmitted in the 1970s by SETI pioneers.

This short video and interactive assessment activity is designed to teach second graders about decomposing decimals into place values up to hundredths.

This short video and interactive assessment activity is designed to teach second graders about decomposing decimals into place values to tenths.

Are you bored by textbooks? Are you overwhelmed trying to keep up with the reading in all your college classes? Deconstructing Management is a podcast created by college students for college students. We make learning management not suck. Each episode is produced by different teams of students and aligns with the OpenStax Principles of Management textbook. We believe it's a better way to learn management, but we might be biased ;-)

Pharo is a clean, innovative, open-source, live-programming environment.

Deep into Pharois the second volume of a series of books covering Pharo. Whereas the first volume is intended for newcomers, this second volume covers deeper topics.You will learn about Pharo frameworks and libraries such as Glamour, PetitParser, Roassal, FileSystem, Regex, and Socket.

You will explore the language with chapters on exceptions, blocks, small integers, and floats.

You will discover tools such as profilers, Metacello and Gofer.

Sal discusses the conditions of matrix dimensions for which addition or multiplication are defined. Created by Sal Khan.

Students learn about nanocomposites, compression and strain as they design and program robots that compress materials. Student groups conduct experiments to determine how many LEGO MINDSTORMS(TM) NXT motor rotations it takes to compress soft nanocomposites, including mini marshmallows, Play-Doh®, bread and foam. They measure the length and width of their nanocomposite objects before and after compression to determine the change in length and width as a function of motor rotation.

This art history video discussion examines Edgar Degas' "The Bellelli Family", 1858-67, oil on canvas (Musee d'Orsay, Paris). Degas was in his mid-twenties when he painted this canvas. It depicts from left to right, the ten-year-old Giovanna, her mother, the artist's paternal aunt Laura, her younger daughter, Giula age 7, and the Baron Gennaro Bellelli. Preperatory sketches for the painting may have been made in Florence where the family was living, the Baron had been exiled from Naples. The picture may have been completed in Paris.
