Stealth Assessment In Video Games, Val Shute
Stealth Assessment In Video Games, Val Shute
2009 - 2019 ACER Research Conferences
Games can be powerful vehicles to support learning, but their success in education hinges on getting the assessment part right. In this presentation, I will explore how games can use stealth assessment to measure and support the learning of competencies critical for the future. I will discuss what stealth assessment is, why it is important, and how to develop and accomplish it. I will also provide examples within the context of a game called Physics Playground that I designed and developed with my team. I’ll share what has been learned by recent research on stealth assessments in games, including: Does …
Measuring Charge Carrier Mobility Of Graphene, Christina A. Harmon
Measuring Charge Carrier Mobility Of Graphene, Christina A. Harmon
Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement
This research reports measurements of electron mobility in liquid-gated graphene. Graphene field-effect transistor (GFET) biosensors are more sensitive to changes in external fields when the mobility is high; therefore increasing mobility will improve sensitivity. Mobility can be calculated from the ratio of sheet conductivity to carrier density. Sheet conductivity was measured using van der Pauw geometry and carrier density was determined from measurements of the liquid-gate capacitance. It is shown that mobility improves after the graphene surface is cleaned by an annealing process.
Measuring Strain In Trusses, Spencer Metzsch
Measuring Strain In Trusses, Spencer Metzsch
Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement
Strain is an important quantity in engineering and materials science that relates the deformation of a material to its original length as a percent. Different materials exhibit particular qualities under loading, for example the amount of strain due to a certain magnitude of force, or the amount of strain that can be borne before failure. This experiment aims to compare the relative strengths of three common truss configurations by measuring the strain in their members under loading.
Does A Simple Lattice Protein Exhibit Self-Organized Criticality?, Alissa A. Runyon, Dana M. Gibbon, Arun Bajracharya
Does A Simple Lattice Protein Exhibit Self-Organized Criticality?, Alissa A. Runyon, Dana M. Gibbon, Arun Bajracharya
Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement
There are many unanswered questions when it comes to protein folding. These questions are interesting because the tertiary structure of proteins determines its functionality in living organisms. How do proteins consistently reach their final tertiary structure from the primary sequence of amino acids? What explains the complexity of tertiary structures? Our research uses a simple hydrophobic-polar lattice-bound computational model to investigate self-organized criticality as a possible mechanism for generating complexity in protein folding and protein tertiary structures.
The Use Of Piezoelectric Actuators In An Energy-Efficient Noise Reduction System, Ian J.M. Johnson
The Use Of Piezoelectric Actuators In An Energy-Efficient Noise Reduction System, Ian J.M. Johnson
Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement
The piezoelectric effect allows for conversion between mechanical stress and electrical impulses. By utilizing this phenomenon, a novel method of sound attenuation was explored and tested in which a piezoelectric plate absorbs part of an incoming sound wave. Reversing the process allows a second plate to produce a phase-inverted wave using the absorbed energy, achieving further reduction through destructive interference.
Capacitance Measurements Of Defects In Solar Cells: Checking The Model Assumptions, Justin R. Davis, Thaddeus Cox
Capacitance Measurements Of Defects In Solar Cells: Checking The Model Assumptions, Justin R. Davis, Thaddeus Cox
Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement
Capacitance measurements of solar cells are able to detect minute changes in charge in the material. For that reason, capacitance is used in many methods to electrically characterize defects in the solar cell. Standard interpretations of capacitance rely on many assumptions, which, if wrong can skew the results. We explore possible alternate explanations for capacitance transitions, which may not be linked directly to defects, such as a non-ideal back contact, and series resistance.
Comparison Of Raised And Flat-Seam Baseballs, Joseph S. Carroll
Comparison Of Raised And Flat-Seam Baseballs, Joseph S. Carroll
Linfield University Student Symposium: A Celebration of Scholarship and Creative Achievement
The difference in seam-height between raised and flat-seam baseballs leads to different different drag and spin forces when the balls are thrown by a pitcher. The goal of this experiment is to measure the difference in vertical deflection of curveball pitches, caused by the different seam-heights.
