Abstract

The purpose of this research was to develop a learning management using scientific representations in stoichiometry for high school students to reach an efficiency criteria ratio (E1/E2) of 75/75. The lesson plans were implemented with twenty seven students from one school in Northern Thailand and the participants were selected through purposive sampling. The lesson plans consisted of five topics, including the law of mass conservation, the law of definite proportions, the volume of gas in chemical reactions, the relationship between the amount of a substance in the chemical equation, and the limiting reagent. The data were collected using worksheets and the stoichiometry achievement test. The results revealed that the efficiency of the learning management using scientific representations in stoichiometry was at a higher than standard criteria ratio (75/75), which is equivalent to 91.97/85.83.

In conclusion, the results implied that the efficiency of the learning management using scientific representations in stoichiometry for high school students corresponds with the hypothesis.
