Technology, when used appropriately, can help make science classroom a site of active learning and critical thinking, furthering student inquiry and connections with the materials. Teachers can use technology to enable students to explore fundamental curriculum issues and answer core questions. Students can use the Internet, electronic databases, applets and other online sources to gather information. They can use spreadsheets, virtual labs, and other programs to store, organize, and analyze information. Students can also integrate multimedia desktop publishing, web publishing, video and audio editing, as well as graphics programs to create and present information in innovative and engaging ways.

There are scores of educators and researchers deeply concerned with how our schools, largely the product of 19th century industrial society, are going to prepare students for the 21st century.

Math Worksheets and Math Practice. Factoring a Quadratic Trinomial by Grouping. Another method for factoring these kinds of quadratic trinomials is called factoring by grouping.

Factoring by grouping can be a bit more tedious, and is often not worth the trouble if you can find the correct factors by some quick trial and error. However, it works quite well when the factors are not immediately obvious, such as when you have a very large number of candidate factors. When this happens, the trial and error method becomes very tedious Factoring by grouping is best demonstrated with a few examples.

Example: The Procedure Given a general quadratic trinomial ax2 + bx + c 1. 2. Hk = ac (h and k are factors of the product of the coefficient of x2 and the constant term) h + k = b (h and k add to give the coefficient of x) 3. Ax2 + hx + kx + c 4.

How It Works: Let M be the month number and D will be the day number. Thus, if you subtract off the 165, what will remain will be the month in hundreds plus the day!

The Thirty Greatest Mathematicians. Click for a discussion of certain omissions.

Please send me e-mail if you believe there's a major flaw in my rankings (or an error in any of the biographies). Obviously the relative ranks of, say Fibonacci and Ramanujan, will never satisfy everyone since the reasons for their "greatness" are different. I'm sure I've overlooked great mathematicians who obviously belong on this list. Please e-mail and tell me! Following are the top mathematicians in chronological (birth-year) order. Earliest mathematicians Little is known of the earliest mathematics, but the famous Ishango Bone from Early Stone-Age Africa has tally marks suggesting arithmetic.

Early Vedic mathematicians The greatest mathematics before the Golden Age of Greece was in India's early Vedic (Hindu) civilization.
