The Effectiveness of Mastery Learning

A study to evaluate the effectiveness of mastery learning for MCAS mathematics tutoring among middle school students was performed. The ASSISTment system was used to create variabilized templates for the creation of mastery learning problem sets. The ASSISTment system was used to generate pre-tests and post-tests to evaluate the overall gain of the students involved in the experiment. The experiment concluded that there was an overall gain in test scores and mastery learning was effective to some extent

Packaging and Optimization of a Digital Holographic Otoscope For Clinical Use

In conjunction with the Massachusetts Eye and Ear Infirmary (MEEI) and CHLST, an optoelectronic holographic otoscope (OEHO) has been developed with the purpose of measuring subnanometer deformations in the human tympanic membrane. The current configuration is not feasible for use in clinical settings. This report details the steps taken to convert the experimental systems of the past to a reproducible, stable, and optimized modular tool. Methods of rapid prototyping and digital holography are introduced for obtaining a new generation of OEHO. Tests pioneering the reflectivity of biologically compatible materials are also conducted for the maximization of laser reflectivity on the surface of the tympanic membrane

Development of a comprehensive mobileassessment of pressure (CMAP) system forpressure injury prevention for veterans with spinalcord injury

Objective: This paper reports the iterative redesign, feasibility and usability of the Comprehensive Mobile Assessment of Pressure (CMAP) system’s mobile app used by Veterans with SCI. Design: This three-year, multi-staged study used a mixed-methods approach. Setting: Minneapolis VA Health Care System, Minneapolis, Minnesota. Participants: Veterans with spinal cord injury (N = 18). Interventions: Veterans with spinal cord injury engaged in iterative focus groups and personal interviews, sharing their needs and desires for the CMAP app redesign. App developers used these data for the redesign. The redesigned CMAP app was tested for six-weeks in users’ homes. Outcome Measures: Quantitative (surveys) and qualitative (interviews) methods measured feasibility for self-management of seating pressure. Qualitative data were audio recorded, transcribed, anonymized, and coded. Survey data were analyzed using summary statistics. Results: After the CMAP system’s redesign, the in-home use interview found: (1) any tool that can assist in prevention and monitoring of skin ulcers is important; (2) the desired key features are present in the app; (3) the main barrier to CMAP use was inconsistent functionality; (4) when functioning as expected, the live pressure map was the central feature, with reminders to weight shift also of high importance. The survey found: power wheelchair users tended to score closer than manual wheelchair users to the positive response end ranges on two separate surveys. Conclusions: Overall both the power and manual wheelchair users reported that they wanted to use the system, felt confident using the system, and that the functions of the system were well integrated.This study was funded by the Department of Defense, number W81XWH-15-1-0484
