Abstract
- The article presents a study on the ability of a student to balance a chemical equation in Florida. The methods of testing the ability of the student to balance chemical reactions by the utilization of multiple choice is presented in this article. A method called the sum of coefficients was used to measure the student's abilities. After the examination, the author became aware of certain types of errors that were negating the validity of the test scores. The details on the experiment which was designed to determine whether the errors were actually significant part of the student's grade was presented.
