Every November, I start steeling myself for the onset of virus season. Since most of the students in our school district elect to receive flu shots, the number of flu cases in our schools is very manageable and the symptoms are fairly benign. The dreaded norovirus, however, is a different story. While many people refer to it as “the stomach flu,” norovirus is actually an RNA virus that causes acute vomiting and diarrhea and is responsible for about 90% of all epidemic non-bacterial outbreaks of gastrointestinal illness in the world. It’s highly contagious, and spreads from person to person through touching contaminated surfaces or through ingesting contaminated food or water.

Over the past few weeks, Peggy and I have been writing about topics raised in an interview with NEA’s Executive Director, John Wilson. We discussed global literacy and methods to stretch school dollars in a challenging economy. This week, we’ve decided to focus on another of the issues raised by Wilson – the importance of technology in education.

This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands. ~Barack Obama

There have been at least six well-documented mass extinctions on Earth over the past 500 million years, a phenomenon that has both puzzled and intrigued scientists for centuries. Various types of organisms on Earth become extinct fairly frequently, but mass extinctions are distinguished by the large numbers of species that become extinct over a relatively short period of time. The Cretaceous-Tertiary extinction, responsible for the demise of the dinosaurs some 65 million years ago, is perhaps the most famous mass extinction. It’s forever branded into our brains from being the topic of feature films, artists’ paintings, and numerous books.

Thanksgiving in America is a time for students and teachers to take a little break from school to reflect on the history of our country and to give thanks for all that we have. For many, it’s a time to take a vacation where we eat WAY too much and get up at crazy hours of the morning to get a head start on the Christmas shopping! In an attempt to help students understand the origin and the meaning of the holiday, many teachers teach Thanksgiving lessons during the time before the holiday. Some teachers choose to focus on the gratitude associated with the season, hoping to instill some of that thankfulness in their students. Other teachers choose to focus more on the historical events in the United States that inspired the holiday.

You are sitting at a meeting with other teachers at your school talking about topics you want to cover this year. A couple of biology teachers are trying to figure out a creative way to teach carbon dating. The chemistry teacher is asking around to see if anyone knows of a good method for teaching chromatography. An English teacher is trying to think up an assignment in persuasive writing. The conversation could go on, but the principal steps to the front of the room to start the meeting. Discussions of field trips, state standards, and test score improvement are going on all around you, but your mind is still on the earlier chat. Is there a way to tie all these topics together to make a more meaningful educational experience for our students?

Autumn is a time of great change and transformation in nature. As a child, I remember the awe I felt watching leaves fall and crunching across them as I walked on the sidewalk. As an adult, I am still in awe of the sights and smells of the season (and I STILL want to jump in the huge pile of leaves, even if it means I’ll have to rake them up again). This week, Joann and I collected resources that tap into this childhood fascination of the changes occurring in nature to teach lessons in many different subject areas.

Although it’s now summer, I know that many teachers are already planning for the coming school year, and thinking about ways to improve their classes. At an end of the year event last month, I overheard an elementary school teacher talking about how students in her class handled stress, and how over the summer she planned to do some research on students and stress management. That got me thinking.

A few weeks ago, my 5th grader sprinted off the bus to tell me that he had performed a hip replacement that day. “Really,” I said, thinking that a new euphemism had been coined for the daily recess football injury. Instead, he burbled excitedly about virtual surgeries they had performed in school that day during computer lab. My interest piqued, I decided to check out the Edheads Web site for myself. The site offers neat online simulations of surgeries and other types of materials.

The resources Joann featured this week are fun examples of how to include interactive maps in your classroom. If you haven’t checked them out yet, you should. Really…who hasn’t wondered where they would end up if they tunneled through the earth? All three resources would be great for a geography classroom, and an interactive piracy map could tie in well in a history class or even an English class if you are reading about pirates.
