Identifying discriminating items for student feedback to principals

, 2018
The primary purpose of this study was to create and test items for student evaluation of principal performance. The items were designed utilizing the five correlates of the effective school and current research on principal behaviors as defined by the School Improvement Model Project at Iowa State University;The study involved 599 students in grades 5,

Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

Advanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.

The effects of inclusive and exclusive item response rule options on item difficulty and discrimination in multiple choice tests

, 2020
The paper investigates the effects of exclusive (all of the above (AOTA)) and inclusive (none of the above (NOTA)) item rule options on item difficulty and discrimination of multiple choice tests. The study adopted experimental research design.

Polarity‐Reversible Photoresponse–Driven Autonomous Wavelength Discrimination in Quantum Dot–Tellurium Thin‐Film Photodetectors via Engineered Energy‐Band Alignment

Advanced Functional Materials, EarlyView.
A quantum dot–tellurium thin‐film photodetector autonomously discriminates visible and infrared wavelengths through polarity‐reversible photoresponses. Engineered carrier separation and gain modulation enable filter‐free multispectral sensing within a single‐device architecture.

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...
