Research output: Contribution to journalArticlepeer-review


The Advanced Placement (AP) Descriptive Chemistry Website allows users to practice chemistry problems. This study involved the redesign of the Website using worked examples to enhance learner performance. The population sample for the study includes users (students and teachers) interested in learning descriptive chemistry materials. The users were randomly selected to receive worked examples. Usage patterns with the Website were analyzed to assess learner performance using the Independent Samples t-test. No important differences were found in learning between the worked example and more conventional strategies.
