Purpose: Prior research indicates that reading difficulties in childhood become more problematic as students move to middle and high school where increasingly challenging material must be learned. Although some older students still struggle with decoding, many more have difficulty constructing meaning from text. Despite research that has identified strategies for teaching students to comprehend wh ...

Purpose: The need for all students to be well prepared in science has been well documented. The purpose of this project is to develop a solar learning lab platform to apply learning in the area of energy science. Project Activities: The researchers will design curricula materials, multi-media video clips, lesson plans, student activities, assessments, and a back-end system to house data generated ...

Purpose: In education research, the standardized mean difference (symbolized by d) is the predominant effect size index. It is calculated as the difference between the treatment-group and control-group means, divided by the pooled standard deviation. Using d allows the impacts of education interventions to be compared even when they have been evaluated using different measures or study designs. Ca ...

LongWave Photonics proposes a terahertz quantum-cascade laser based swept-source optical coherence tomography (THz SS-OCT) system for single-sided, 3D, nondestructive evaluation (NDE) of non-conductive materials. The THz SS-OCT system uses a frequency tunable QCL array to generate an interferometric signal between a reference mirror, and a sample. An algorithm is used to transform this signal in ...

Analogous to the CubeSat standardization of micro-satellites, the SPORE flight system architecture will utilize a modular design approach to provide low-cost on-orbit operation and recovery of small payloads. The Phase 1 investigation will evaluate a scalable flight system architecture consisting of a service module for on-orbit operations and deorbit maneuvering, and an entry vehicle to perform ...

Busek proposes to prove the feasibility of a Mg Hall effect thruster system that would open the door for In-Situ Resource Utilization (ISRU) based solar system exploration. Elemental magnesium has favorable thermophysical properties and is very easy to ionize. The estimated specific impulse for a high efficiency magnesium Hall thruster operating off of a standard 400 V power processing unit is 5 ...

Physical Sciences Inc. (PSI) together with the University of Connecticut (UCONN) proposes to demonstrate the improved fuel cell catalyst support durability offered by directly incorporating nitrogen functionality into graphitic carbon supports. In Phase I, PSI will utilize the functionalized carbon support in the construction of single cell fuel cells in order to demonstrate the performance and d ...

The proposed effort will develop a technology to wirelessly and efficiently transfer power over hundreds of meters via resonant inductive coupling. The key innovation of this approach is the use of dielectricless high-temperature superconducting (HTS) coils to overcome the limitations in efficiency and range of existing solutions. This approach is informed by existing research models that predic ...

For this NASA STTR program, we propose to develop a novel superlattice-based near infrared to midwave infrared avalanche photodetector (APD) grown on InP substrates for single photon counting applications at high operating temperatures on the order of 200K accessible using thermoelectric coolers. This enables a detector with broad spectral response spanning 0.9 to 4 & #956;m wavelength with reduce ...

NASA is researching various concepts, procedures, standards, and technologies intended for NextGen Airspace. Complex, distributed airspace simulations that utilize experimental testbeds (e.g., Multi Aircraft Control System, or MACS) are vital research tools for these projects. However, managing the various complexities and coordination of agent-supported separation assurance can be challenging. Th ...
