The Impact Of Standardized Testing On Student Performance In The United States, Stephanie Linden
The Impact Of Standardized Testing On Student Performance In The United States, Stephanie Linden
Pell Scholars and Senior Theses
In the United States, the current trend in education is the dependence on standardized testing to improve our current education system. The No Child Left Behind Act of 2001 mandates higher test scores and improved academic performance in schools nation-wide, especially inner city schools. This thesis will attempt to evaluate whether standardized testing and the methods used to assess high performance has helped to create a better education system in the United States, or whether it has hindered student performance. There has been much discussion about this topic, some positive and some not. In this paper I will present both …

Electrochemical Detection Of Prostate Carcinoma Biomarkers Using Nanotechnology, Kathryn Leonard
Pell Scholars and Senior Theses
The first chapter of this thesis speaks about prostate specific antigen, carbon nanotubes and horseradish peroxidase. The second chapter discusses the electrochemistry and catalysis of horseradish peroxidase (HRP) and myoglobin (Mb) covalently attached to vertically aligned carbon nanotube arrays used as a tranducer. Cyclic voltammetry results gave quasi-reversible FeIII/FeII voltammetry and electrochemical catalysis involving catalytic reduction of hydrogen peroxide for both the iron-heme enzymes in myoglobin and horseradish peroxidase coupled to the carboxylated ends of the carbon nanotube arrays by amine bioconjugation reactions. Reduction peak currents gave linear relationships with scan-rates, typical of thin layer voltammetry. Results suggest that the …
