Standards for Mathematical Practice » Use appropriate tools strategically. Mathematically proficient students consider the available tools when solving a mathematical problem. These tools might include pencil and paper, concrete models, a ruler, a protractor, a calculator, a spreadsheet, a computer algebra system, a statistical package, or dynamic geometry software. Proficient students are sufficiently familiar with tools appropriate for their grade or course to make sound decisions about when each of these tools might be helpful, recognizing both the insight to be gained and their limitations. For example, mathematically proficient high school students analyze graphs of functions and solutions generated using a graphing calculator. They detect possible errors by strategically using estimation and other mathematical knowledge. When making mathematical models, they know that technology can enable them to visualize the results of varying assumptions, explore consequences, and compare predictions with data.

Computational Skills for Biology Students June 2006 Why is it important to develop computer savvy students of biology? Understanding quantitative research is critical to grasping biology. A good fraction of modern biology is heavily quantitative. Photo: Microsoft Images. Gross: A good fraction of modern biology is heavily quantitative, and one of the main complaints that I have heard for a very long time from biologists is that students do not have the capability to carry out the basic quantitative research that is critical to all modern biology across the spectrum. Graphing is a required basic skill. One of the most distressing comments has been about the simplest things: reading, interpreting, and producing graphs—simple graphs that students have seen again and again since they were in elementary and middle school. Perhaps the simplest illustration of this point is the basic way we communicate science, which requires a quantitative framework for understanding. How do teachers go about helping students become more computer savvy?
