At the secondary level, there has long been an argument about the appropriate mix of qualitative and quantitative content in chemistry education. Teachers struggle to provide relevant contexts for the mathematical skills that are necessary to understand chemical reactions. This new, interactive e-book from NSTA will help teachers achieve that balance, providing relevant examples in graphic format and clear explanations of the reasons why.

Chemical Reactions is primarily designed as a tool for professional development for physical science and chemistry teachers. It uses many of the "science objects" NSTA has developed to enhance instruction over the years--images, simulations, and video--as well as new material to illustrate chemistry concepts. Wrapped around those images is clear, coherent text with links to sections on student misconceptions, pedagogy, and standards. Teachers at the secondary level will especially benefit from the complete discussion of the progressions in understanding from K-8 that are included, since it is easy to overestimate student experience with a world of interactions that they cannot see or sense.

In the Next Generation Science Standards, PS1.B calls for an understanding of "chemical processes, their rates, and whether or not energy is stored or released ... the balance between reactions and reverse reactions ... and that atoms are conserved...." This interactive book covers all of these content areas and has the potential for much more. The animations and simulations, supported by the text, are easily projected to the entire classroom. …
