Small‐ and large‐group instruction and a didactic method in mathematics for low‐performing adolescents: results from a randomized field experiment

The Scandinavian Journal of Economics, EarlyView.
Abstract There is an increasing focus on helping low‐performing adolescents in school. We have randomly exposed low‐performing adolescents in mathematics in grade 8 to variations in key school inputs: teacher training, teaching material, and group size.

Graph neural networks for the localization of faults in a partially observed regional transmission system

Scandinavian Journal of Statistics, EarlyView.
Abstract Localization of faults in a large power system is one of the most important and difficult tasks of power systems monitoring. A fault, typically a shorted line, can be seen almost instantaneously by all measurement devices throughout the system, but determining its location in a geographically vast and topologically complex system is difficult.

On high‐dimensional variance estimation in survey sampling

Scandinavian Journal of Statistics, EarlyView.
Abstract Using predictive modeling at different survey stages can improve the accuracy of a point estimator or help tackle issues such as missing values. So far, the existing literature on predictive models for survey data has predominantly concentrated on scenarios with low‐dimensional data, wherein the number of variables is small compared with the ...

Elementary students' argumentative and explanatory mathematical writing about fractions

School Science and Mathematics, EarlyView.
Abstract Mathematical writing (MW) is an important yet underutilized form of mathematics discourse. Given the lack of attention to MW, there are few resources to support the implementation and assessment of MW. This study responds to the lack of resources by describing a MW unit focused on fractions that was implemented during a summer school program ...
