Problem Solving Abilities of Physical Science Students in Stoichiometry

Problem solving is an integral part of any physical science course. In recent years many research studies investigated students' misconceptions and problem solving strategies on Stoichiometry problems (Martin Fach 2006). This study attempted to assessed and analyzed the problem solving abilities in Stoichiometry. This study utilized descriptive method of research and employed inferential statistics. The following conclusions were established: (1) The problem solving abilities of students toward Stoichiometry were good in Molecular or Formula Mass and Empirical Formula and Molecular Formula and excellent in the Mole and Percentage Composition from Formulas, (2) There is a significant relationship between the problem solving abilities and income, (3) The problem solving abilities is not significantly related with the income of parents except molecular or formula mass and empirical formula is significantly correlated in monthly income of parents, and (4) The student level of problem solving abilities is highly and significantly correlated with conceptual understanding on Stoichiometry. The following recommendations were drawn: (1) Chemistry teachers should challenge skilled students to help their classmates (2) Teachers should device simple techniques for teaching concepts in Stoichiometry to motivate students to solve and appreciate problem solving activities.
