A 35-year-old police shooting instructor with a 4-year history of Bowen's disease of the nail bed on his right index finger confirmed histologically, was successfully treated with photodynamic therapy (PDT). Four cycles of PDT were used with two different photosensitizers: 20% 5-amino-levulinic acid oil in water emulsion and methyl amino-levulinate (Metvix) cream. The lesion was successfully tr...

Assessment data were collected from multiple institutions in fall 2013 and winter 2014 to measure the conceptual understanding and perspectives of statistics for students taught under a randomization-based curriculum. We concentrated on identifying student and instructor characteristics that were associated with student gains and determining whether there was a disparity in student gains based ...

BACKGROUND Clinical education is the heart of the nursing education program. Effective nursing clinical instructors are needed for graduating the future qualified nurses. There is a well-developed body of knowledge about the effectiveness of clinical teaching and the instructors.

Research has demonstrated that Peer Instruction (PI) is an attractive pedagogical practice in computer science classes. PI has been shown to improve final exam performance over standard lecture, reduce failure rates, contribute to increased retention, and be widely valued by students. In addition, a recent study using isomorphic (same-concept) questions found that students are learning during p...

A geothermal power plant multiple simulator for operators training is presented. The simulator is designed to be installed in a wireless local area network and has a capacity to train one to six operators simultaneously, each one with an independent simulation session. The sessions must be supervised only by one instructor. The main parts of this multiple simulator are: instructor and operator’...

This research paper reviews the literature on class size, and examines the impact of class size on successful course completion when controlling for instructor and class specific variables, the gender and ethnicity of a student, the reading abilities of students, the ...

In this lecture, we consider online network design and a new analysis framework based on tree embeddings introduced in [3]. We will start with the most basic online network design problem called the online Steiner tree problem. Then, we review the necessary background on tree embeddings for the analysis framework and apply the framework to analyze a natural greedy algorithm for the online Stein...
