The effectiveness of a Chemistry Learning Material (CLM) that is based on a Problem Solving Competence Model (PSCM) is the main focus of this study. The PSCM posits that two factors: (1) perceived usefulness and (2) metacognitive regulation—strongly influence students’ problem solving performance. The PSCM-based CLM covered four topics namely: (1) ways of expressing concentrations of solutions, (2) colligative properties, (3) chemical equilibrium, and (4) acids, bases, and salts. The PSCM-based CLM was utilized in the teaching and learning of tertiary level General Chemistry to an intact class (N = 31) for 10 weeks during the second semester of school year 2015–2016 at a state university in Manila, Philippines. Across all the four topics, results of the paired-sample t-test revealed that the posttest scores were significantly higher than the pretest scores. This is suggestive that the design and structure of the CLM improved students’ problem solving performance. Findings provided evidence that use of the PSCM-based CLM enhanced students’ problem solving strategies, facilitated increase on students’ perceived usefulness belief and metacognitive regulation. Generally, students perceived that the various activities in the CLM improved their problem solving skills and enabled them to solve Chemistry problems in a more systematic manner.
