Physics Faculty Use Of Example Solutions In Teaching Introductory Physics, William O. Mamudi
Physics Faculty Use Of Example Solutions In Teaching Introductory Physics, William O. Mamudi
Masters Theses
This study investigates how physics faculty perceive and use features of example problem solutions. Thirty physics instructors from diverse institutions participated in semi-structured interviews. In addition to open-ended questions, three example problem solution artifacts were used to focus on specific solution features. Data were analyzed to identify instructors’ goals for the use of example solutions and whether their goals were consistent with the solution features that they valued and used. The study concludes that many faculty have three major goals: keeping students cognitively involved, helping students become better problem solvers, and supporting students in learning physics. The study also found …
The Dissemination And Effective Use Of Physics Education Research In Undergraduate Instruction, Trevor Stefanick
The Dissemination And Effective Use Of Physics Education Research In Undergraduate Instruction, Trevor Stefanick
Masters Theses
Based on the results of a national survey of physics faculty, a set of interviews was conducted of 70 physics faculty from a diverse set of institutions. The interviews included questions about the dissemination and effective use of curricula and instructional strategies based on Physics Education Research (PER), focused to obtain recommendations to the PER community that might help to spread the use of these PER-based materials. Approximately half of the interviews (those with faculty who indicated knowledge about or use of Peer Instruction) have been previously analyzed. This project is the analysis of the 38 interviews that were conducted …
The Variation Of Hydrogen Concentration In Ni/Mgh Thin Film With Temperature, Rex Nyadaufe Taibu
The Variation Of Hydrogen Concentration In Ni/Mgh Thin Film With Temperature, Rex Nyadaufe Taibu
Masters Theses
The thermal stability of Ni/MgH thin film deposited on Si substrate by Unbalanced Magnetron Physical Vapor Deposition has been investigated using Ion Beam analysis (DBA) techniques. Rutherford Backscattering Spectrometry (RBS) and Non-Rutherford Backscattering Spectrometry (NRBS) have been used to find the composition of Magnesium, Nickel and Oxygen. Elastic Recoil Detection Analysis (ERDA) has been used to determine the concentration of hydrogen at each level of heating. Heating was done in the Ultra High Vacuum (UHV) environment using a non gassy button heater. Ni/MgH sample had lost most of its hydrogen after being heated to a temperature of about 125°C in …
