Doctor of Education in Secondary and Middle Grades Education Dissertations
The Law of Conservation of Matter is a crosscutting concept in science that has implications for all disciplines of science. Conservation of Matter concepts are interwoven into all middle school and high school science courses both within the Next Generation Science Standards (NGSS) and the Georgia Standards of Excellence (GSE). For students to become scientifically literate, teachers of science must be able to articulate the content accurately to students and anticipate student difficulties and misconceptions in understanding the content. In order to ensure that students successfully learn said content, science teachers must possess both content knowledge and pedagogical content knowledge. …

Symposium of Student Scholars
In chemistry, three-dimensional models are used to help students understand advanced topics. Understanding what causes an increase in cognitive load is critical because a greater cognitive load is often related to three-dimensional models. To understand cognitive load in relation to models, students were given both a virtual simulation to complete and three-dimensional models to use. Question four of the activity was further analyzed and broken down into smaller sections based on the molecules involved. With the three-dimensional modeling kits, the students were given water molecules, sodium ions, and chloride ions. The students were asked to figure out if certain molecules …
