520 $a Stoichiometry is a mathematical Chemistry concept. One use of stoichiometry determine how much product can be formed from a given amount of reactants.
520 $a The purpose of this study was to teach a variety of stoichiometric concepts to high school students. During the unit, students learned to do conversions related to balanced chemical equations, determine which reactant was the limiting reactant, and to determine percent yield. This was accomplished using lecture, class discussion, working through sample problems as a class, and a variety of laboratory activities. The majority of the unit was spent doing activities with the goal that students would be more engaged than if they were simply doing homework problems. Data were collected using pre-unit and post-unit surveys, pre-unit and post-unit tests, and answers from student work.
520 $a Test averages from the current year and 2005-2006 year were compared. Although the averages were not significantly different, the grades were higher this year. Also, based on student comments and teacher observations, the students seemed to enjoy the unit more and retained the information longer compared to previous years.
