Developing the Ability to Apply Chemical Knowledge for Students through Experience of “Visiting the Clean Water Supply Station”

Abstract

The ability to apply chemical knowledge to practice is an important ability that needs to be developed for students when learning Chemistry. This research focuses on developing the ability to apply chemical knowledge to practice for high school students through experience. The evaluation of the development of the ability to apply chemical knowledge to practice for students is implemented following 10 criteria and 4 levels of expression of the ability at two different points, before and after participating in the experience. The statistic parameters such as effect size (ES) and independent t-test have been determined in order to verify the effectiveness of the pedagogical experiment. The research results show that, after the experiment, the average scores of evaluation criteria of students’ ability to apply chemical knowledge to practice are higher than that at the time before the experiment. The ES and independent t-test parameters also show the change before and after the experiment is affected by the experimental methods. Thus, the ability to apply chemical knowledge to practice of students is initially improved through experience.
