Professional Development to Support Instructional Improvement: Lessons from Research
This paper acknowledges the issue of nonstrategic use of professional development resources and describes lessons from research on how professional development could be better designed to achieve desired impacts on instruction and student learning.

Report Tackles Assessment Design for Next Generation Science Standards
If the new science standards could be summed up in one grand sentence, it would likely be – “It is not what you know, but how you use and apply what you know that makes a real difference for science learning.” The Next Generation Science Standards (NGSS) emphasize that all students should learn science by…

Automatic Speech Transcription for Low-Resource Languages — The Case of Yoloxóchitl Mixtec (Mexico)
In the present study, we focus exclusively on progress in developing speech recognition for the language of interest, Yoloxóchitl Mixtec (YM), an Oto-Manguean language spoken by fewer than 5000 speakers on the Pacific coast of Guerrero, Mexico.

Privacy- preserving speech analytics for automatic assessment of student collaboration
This work investigates whether nonlexical information from speech can automatically predict the quality of small-group collaborations. Audio was collected from students as they collaborated in groups of three to solve math problems.

Coping with Unseen Data Conditions: Investigating Neural Net Architectures, Robust Features, and Information Fusion for Robust Speech Recognition
This work investigates the performance of traditional deep neural networks under varying acoustic conditions and evaluates their performance with speech recorded under realistic background conditions that are mismatched with respect to the training data.
