Studyblue.com is a website that helps you make flashcards.
Here is what the website looks like:
The cool thing about this website is that it has more features than just flashcards. It is really easy to use, I figured it out within minutes, and allows you to collaborate with classmates. When you first enter the site, you have to register (it's free, don't worry!) and then you can add your classes. Sometimes it will already have your classes on the site, making resources easier to access. You can take notes on the site and then make flashcards with more than one side, allowing several definitions for one term. You can look up people in your class and share notes with them, or even people in other classes. The flashcards part is the one that will help students learn dates and people better but it would also be good for them to work with each other online to share ideas that they might not have caught in class.
I have never used digital flashcards and this one seems really cool because it more resources than just the cards. It is something that I may very well use in my future classroom and introduce to my students.
