What Can General Chemistry Students Learn From External Representations Of Acid- Base Titrations?, Nicole Baldwin
UNLV Theses, Dissertations, Professional Papers, and Capstones
Laboratory activities are a prevalent and essential part of chemistry learning because of their potential to help students develop problem solving abilities, visualize chemistry concepts learned in lecture, and gain practical skills. However, learning in the laboratory environment is not without its challenges. For example, cookbook-style chemistry laboratories can promote superficial learning, and cognitive overload can result from the study of new concepts and the use of new procedures in this environment. Multiple pedagogies and supports have been developed to address challenges such as these. The current research focuses upon external representations that are commonly used to support learning in …
The Activity Of Abstraction In Physical Chemistry Problem Solving And Instruction, Jessica M. Karch
The Activity Of Abstraction In Physical Chemistry Problem Solving And Instruction, Jessica M. Karch
Graduate Doctoral Dissertations
Productive problem solving, concept construction, and sense making occur through the core process of abstraction. Although the capacity for domain-general abstraction is developed at a young age, the role of abstraction in increasingly complex and disciplinary environments, such as those encountered in undergraduate STEM education, is not well understood. Undergraduate physical chemistry relies particularly heavily on abstraction because it uses many overlapping and imperfect mathematical models to represent and interpret phenomena occurring on multiple scales. To reconcile these models, extract meaning from them, and recognize when to apply them in problem solving requires processes of abstraction. This dissertation aims to …
An Analysis Of Factors Influencing Chemistry Students’ Choice Of Major And Career, Jennifer Marie Ribble
An Analysis Of Factors Influencing Chemistry Students’ Choice Of Major And Career, Jennifer Marie Ribble
Masters Theses
In recent years there has been a push to increase the number of STEM graduates in the United States in order for the nation to retain its position as a global leader in the sciences. If educators are to address recruitment and attrition issues in STEM fields it is important to understand student perspectives related to choosing both a major and a career in chemistry. The present study explores the decision-making process students utilize to choose chemistry as a major and as a career, their perception of what careers are available to someone with a degree in chemistry and what …
