Walden Dissertations and Doctoral Studies

Many students have problems learning stoichiometry, a complex mathematical chemistry concept used to determine how much product will be produced or formed from a given quantity of reactants. The problem addressed in this study was teachers' lack of understanding of how to teach stoichiometry in a Midwestern urban school district. The conceptual framework of the study was based upon constructivist theory. A qualitative narrative approach was used to obtain the perceptions of 5 high school chemistry instructors related to their experiences, successful or unsuccessful, in teaching stoichiometry to students in Grades 10 and 11. Data were gathered through face-to-face interviews, …

Seeing The Chemistry Around Me – Helping Students Identify The Relevance Of Chemistry To Everyday Life, Tracy Lynn Moore

Dissertations

The study attempted to determine whether the use of a series of reading and response assignments decreased students’ perceptions of chemistry difficulty and enhanced students’ perceptions of the relevance of chemistry in their everyday lives. Informed consent volunteer students enrolled in General Chemistry II at a community college in the southeastern United States during the Spring 2012 semester participated in this study. Students were assigned to read a series of short articles that connect chemistry to a specific aspect of everyday life and then answer a series of questions for each article. Open-response research instruments (initial questionnaire and final questionnaire) …
