Numbers Count! http://bioquest.org/numberscount The Numbers Count Project provides data, tools, and curricular materials for use in the classroom to support student observation, experimentation and modeling.

<div style=”text-align:center;width:100%” ><img src=”http://www.mathtran.org/cgi-bin/mathtran?D=3;tex=ex%3A%20%5C%3B%20%5Cfrac%7B1%7D%7B3%7D%0A%20%20%20%20%20%20%20%20%20%20%20%20″ alt=”ex: \; \frac{1}{3}
“/></div>
\frac{dN}{dt}=rN\left(1-\frac{N}{K}\right)
All you need to do is write the equation in LateX, convert to HTML, and copy the HTML into your blog.
It has an easier editor to write equations, similar to Word’s equation editor, i.e., point and click on symbols and it will figure out the correct LateX language.

This necessitates a change in how we educate our students. Critical to their ability to navigate this environment is early exposure to authentic and large data sets. Students should explore data and develop their own questions. An excellent resource is Gapminder (http://www.gapminder.org/), which allows students to download data sets into Excel. Examples where I have used this can be found in the Oakwood University workshop (http://bioquest.org/oakwood2008/?page_id=374)  where a worksheet on “Cancer Global View” gives an introduction to Gapminder and provides some in-class activities.

The experiment showed that evolution happened in our E. coli and phage system and only after taking this into account did the model make the correct predictions.
