For decades science educators and educational institutions have been concerned with the status of science content being taught in K-12 schools and the delivery of the content. Thus, educational reformers in the United States continue to strive to solve the problem on how to best teach science for optimal success in learning. The constructivist movement has been at the forefront of this effort. With mandatory testing nationwide and an increase in science, technology, engineering, and mathematics (STEM) jobs with little workforce to fulfill these needs, the question of what to teach and how to teach science remains a concern among …

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) …

Investigating Macroscopic, Submicroscopic, And Symbolic Connections In A College-Level General Chemistry Laboratory, Felicia Culver Thadison
Dissertations
Explanations of chemical phenomena rely on understanding the behavior of submicroscopic particles. Because this level is “invisible,” it is described using symbols such as models, diagrams and equations. For this reason, students often view chemistry as a “difficult” subject. The laboratory offers a unique opportunity for the students to experience chemistry macroscopically as well as symbolically. The purpose of this investigation was to determine how chemistry lab students explained chemical phenomenon on the macroscopic, submicroscopic, and representational/symbolic level. The participants were undergraduate students enrolled in an introductory level general chemistry lab course. Students’ background information (gender, the number of previous …
