Dimensional Analysis CAT

Project Overview

Because problem solving is an indispensable part of chemistry, it is important that students develop straight forward techniques that will help them become good problem solvers.  The technique most often employed in solving unit conversion problems is called dimensional analysis (also called factor-label method).  

Also, because it is important to ascertain if students have actually grasped how to perform unit conversion problems using dimensional analysis after it has been presented in lecture, a simple classroom assessment technique (CAT) has been developed.  

Thus, the purpose of this learning object is to administer a "CAT", which uses real-time data, to ascertain if students have developed the ability to solve unit conversion problems.  After analyzing the information collected from this instrument, the teacher who uses it, will be better able to refocus their teaching, if necessary, to help students make their learning more effective and efficient
