Tech provides more usable time.

One of the reasons teachers use technology is that it saves time and effort. Of course many tools are designed to reduce the time and effort it takes for instructors to produce material. Examples of this include test generators and word processors. Today, though, I want to focus on our students during class time. Unfortunately, students can be left to stare into space as we take time to draw something out on the over head or sketch an equation on the whiteboard.

One of the greatest tools I have found for math teachers is the Desmos online calculator. The power of this application lies in the fact that a teacher can manipulate equations and the students can instantly see how the graph of that equation changes in response. A teacher told me recently how excited he is that he no longer has to sketch graphs out by hand while teaching. "And you know that half the kids start day dreaming when we do that", he added. With Desmos, he can use his time to explain concepts and cut down on the wandering minds.

There are also several interactive science sites that are very good. The Dynamic Periodic Table is excellent, for example. During a lesson, you need only hover over sections of the table to bring up important information. It's great for answering student questions or covering material clearly and quickly. Biology teachers love the Cells Alive online cellular models for the same reason.

For language arts, Google docs is a great time saver. This online suite of programs allows users to create presentations, documents and spreadsheets for free. It also allows users to collaborate on any of those files in real time.  The reason this cuts down on dead air is that no one has to wait around for group members to read over material and make comments. Everything in the document is written simultaneously, so everyone in the group can read everything while it is being typed. You as an instructor can also comment on student writing in real time. This means that an entire class can be writing while you make encouraging comments on each paper. All of this is done simultaneously and all without interrupting anyone's train of thought.

Class time should really be used for learning, not waiting for us to draw or read over material. The technology I've discussed is a great start, but there's so much more. What sorts of tools have you found to get more learning out of the limited time you have in class?

On Tradition

We do what we have always done because it works. And hey, why reinvent the wheel? Besides, we have so many things we have to get done that it's hard to find time to learn a new way of doing things. The thing is, it turns out that our ways are often inefficient or less productive than some alternatives.

With a new semester upon us, it may be time to try a few new tools. Below, I list some of my favorite online tools to improve teaching in the next 18 weeks. Give them a try. You may find yourself getting more done in less time, for free.

Google docs + Google calendars
I've written about this mash-up before. Google calendars is an easy to use schedule that you can work on at any time and on any computer that's handy. Calendars also has a nice feature that allows you to attach any file to an event as long as it is already in your Google docs account. That opens up the possibility of attaching lesson plans, tests and student samples. Since you can make any of those files private, you never have to worry about anyone else in the world seeing sensitive documents.

Edmodo
Students love social media for good reasons; it's fun, engaging and it makes learning easier. Unfortunately, there are so many dangers and pitfalls to using sites like Facebook or Twitter. The solution is a site designed specifically for educators to communicate with their students. Parents have full access to their own student's activities and teachers moderate all discussions. There is no outside communication and students don't have the option to talk to the outside world. Better yet, you can make self-grading quizzes and polls for free!


Desmos Graphing Calculator
Students are given all sorts of wonderful technology in schools. They are still being asked to buy expensive calculators. Finally here is a free online solution. Help kids learn to do math without expecting them to buy equipment.

Prezi
Perspective matters. Much of what we talk about in class deals with large scale vs. small scale. Consider these questions: What does a water molecule have to do with whether you have a desert or grassland? How did the Delaware river affect George Washington? What does the hight of a tree and the length of it's shadow have to do with a protractor you hold in your hand?
Prezi is an online presentation site that creates unique, beautiful presentations. Kids love them!

Educational Youtube
Finally! A way to get good educational videos at school! You don't have to worry about crude jokes or wardrobe malfunctions. Its all good stuff here. Well, that's mostly true. Unfortunately, suggestive videos are still sometimes suggested on the right hand side of the screen. You can't watch them, but the suggestive picture is there along with the provocative title. You'll just need to be a bit careful even when the video you want to watch is great.
