Our analytic sample consists of almost 4,000 tenured and tenure-line faculty from 31 research universities. A large majority of faculty report disruptions to research due to the pandemic, with time spent moving instruction online listed as the most common cause (80%), followed by travel restrictions (80%) and inability to focus attention (66%). Although the extent of research disruption varied across academic disciplines, the reasons for disruptions were remarkably similar across disciplines. Forty-two percent of junior faculty stated they were likely to extend their tenure clocks due to the pandemic.}, number={10}, journal={TEACHERS COLLEGE RECORD}, author={Umbach, Paul D. and Porter, Stephen R. and Willis, Chris}, year={2023}, month={Oct}, pages={131–143} }

Because the public and private school sectors administer different assessments, we recruited approximately 700 students to take a common, nationally normed, standardized test. Matching on baseline achievement and rich demographic data, we use a quasi-experimental inverse propensity weighting approach to maximize comparability between the public and private school student samples. Our preferred specification examines first-year effects for new Opportunity Scholarship students, revealing positive estimates of .36 SD in math and .44 SD in language; there is no effect on reading scores. Results for renewal students are statistically significant in language scores only. In further analyses, we estimate separate effects for private schools that regularly administer another version of the assessment used in this study, the Iowa Test of Basic Skills. We conclude by discussing policy implications.}, number={1}, journal={AERA OPEN}, author={Egalite, Anna J. and Stallings, D. T. and Porter, Stephen R.}, year={2020}, month={Jan} }

The items on the IPL-S are grouped into scales measuring five dimensions of science instruction: Low-level Sense-making, High-level Sense-making, Communication, Integrated Practices, and Basic Practices. As part of the current validation study, 206 elementary teachers completed 4137 daily log entries. The purpose of this paper is to provide evidence of validity for the IPL-S’s scales, including (a) support for the theoretical framework; (b) cognitive interviews with logging teachers; (c) item descriptive statistics; (d) comparisons of 28 pairs of teacher and rater logs; and (e) an examination of the internal structure of the IPL-S. We present evidence to describe the extent to which the items and the scales are completed accurately by teachers and differentiate various types of science instructional strategies employed by teachers. Finally, we point to several practical implications of our work and potential uses for the IPL-S. Overall, results provide neutral to positive support for the validity of the groupings of items or scales.}, number={3}, journal={International Journal of Science Education}, publisher={Informa UK Limited}, author={Adams, Elizabeth L. and Carrier, Sarah J. and Minogue, James and Porter, Stephen R. and McEachin, Andrew and Walkowiak, Temple A. and Zulli, Rebecca A.}, year={2017}, month={Feb}, pages={335–357} }

As reported in other groups of patients with special needs, many individuals with a visual impairment may only seek oral health care when a problem arises, such as pain. Visual impairment may have a negative effect upon oral hygiene with many blind and partially sighted individuals having worse oral hygiene than sighted peers.
