Learn how a perceptron works and program a simple example in Python in this artificial intelligence science project.

Today we’re going to go a little meta and talk about how computer science can support learning with educational technology. We here at Crash Course are big fans of interactive in-class learning and hands-on experiences, but we also...

So we've talked a lot in this series about how computers fetch and display data, but how do they make decisions on this data? From spam filters and self-driving cars, to cutting edge medical diagnosis and real-time language translation,...

Paul Andersen explains how he is using the blended learning cycle in his science classroom. This cycle moves through the following steps; QUestion, Investigation/Inquiry, Video, Elaboration, Review and Summary quiz

In this video,Paul Andersen introduces his learning mindsets framework—pairs like curious vs. skeptical and collaborative vs. independent—that help students adapt, reflect, and grow through positive, explicit learning strategies.

In this video Paul Andersen outlines the AP Environmental Science course. He explains how environmental science studies the interaction between earth and human systems. A planetary boundary model is used to explain the importance of...

Null results often get a bad rap, sometimes characterized as a study "finding nothing," but there's a lot we can learn from studies whose results fail to support their hypotheses.

Squeaks and Mister Brown are making popcorn for all of their friends, and learning all about how heat makes popcorn kernels pop!

A brown thrasher knows a thousand songs. A wood thrush can sing two pitches at once. A mockingbird can match the sounds around it - including car alarms. These are just a few of the 4,000 species of songbirds. How do these birds learn...

Squeaks and Mister Brown learn all about how to use brine to make homemade pickles!

Ancient skeletons can tell us a great deal about the past, including the age, gender and even the social status of its former owner. But how can we know all of these details simply by examining some old, soil-caked bones? Farnaz Khatibi...

Today, we’re moving on from artificial intelligence that needs training labels, called Supervised Learning, to Unsupervised Learning which is learning by finding patterns in the world. We’ll focus on the performing unsupervised...

Today we’re going to teach John Green Bot how to tell the difference between donuts and bagels using supervised learning! Supervised learning is the process of learning WITH training labels, and is the most widely used kind of learning...

People say insects are the food of the future. They’re more environmentally sustainable and more humane than other sources of animal protein. Can they really catch on in western diets? I’m a pretty adventurous eater, but I’ve never...

Reinforcement learning is particularly useful in situations where we want to train AIs to have certain skills we don’t fully understand ourselves. Unlike some of the techniques we’ve discussed so far, reinforcement learning generally...

When technologist Luis von Ahn was building the popular language-learning platform Duolingo, he faced a big problem: Could an app designed to teach you something ever compete with addictive platforms like Instagram and TikTok? He...

Today, we're going to combine the artificial neuron we created last week into an artificial neural network. Artificial neural networks are better than other methods for more complicated tasks like image recognition, and the key to their...
