Can teaching be taught? Improving teachers' pedagogical skills at scale in rural Peru

Quantitative Economics, Volume 16, Issue 1, Page 185-233, January 2025.
We evaluate the impact of a large‐scale teacher coaching program in Peru, a context with high teacher turnover, on teachers' pedagogical skills and student learning. Previous studies find that small‐scale coaching programs can improve teaching of reading and science in developing countries.

Research on teachers of colour and minoritised teachers in majoritarian education systems: A scoping review of the literature in the last two decades

Review of Education, Volume 12, Issue 3, December 2024.
Abstract The world map is changing due to waves of immigration, population and demographic changes in mainland Europe and North America. There is a growing need for a more diverse teacher workforce to close the racial and ethnic gap between students and teachers in populations with high diversity.

Polarization Vector Rotations: Real, Spurious, Hidden and Imaginary

Galaxies, 2016
Large and variable polarization is an inherent property of a majority of blazars. Systematic rotations of the polarization vector have been claimed for several blazars. In some cases, however, the reality of these rotations may be questionable.

Lessons from the apparent peculiar nature of the star TYC 6544‐3483‐1

Astronomische Nachrichten, Volume 345, Issue 4, May 2024.
Abstract We report a radio and optical study of the star TYC 6544‐3483‐1 originally selected as a follow‐up target in the course of our efforts to cross‐identify Galactic high‐energy sources. The star by itself finally turned out to be a very ordinary main‐sequence star despite the initial expectations that apparently pointed to the contrary.

Long‐term impacts of primary school scholarships: Evidence from Cambodia

Journal of Policy Analysis and Management, Volume 43, Issue 1, Page 10-38, Winter 2024.
ABSTRACT This randomized trial investigates the long‐term effects of a primary school scholarship program in rural Cambodia. We estimate impacts—9 years after program inception—on educational attainment, cognitive skills, socio‐emotional outcomes, labor market outcomes, and well‐being.

Variability of Blazars and Blazar Models over 38 Years [PDF]

Galaxies, 2016
Since 1978, when BL Lac objects and violently variable quasars were married to become “blazars”, physical interpretations of the phenomenon have evolved. Remarkably, though, the general picture of relativistic jets beaming their radiation in our direction, proposed that year by Blandford and Rees, remains intact.
