When in doubt, asking a peer can be very helpful. Students learn a lot of social strategies from peers. However, stated preference studies have found that for elementary school students with math questions, they prefer to ask their teacher for help.

As part of an APEC educational project on the cross-cutting concept of energy, researchers and teachers from 6 countries spent 8 months designing, testing and implementing a pilot STEM public class with two schools from Chile and one from the US. One

This paper studies a semi-linear system of equations in $$ {\mathbb{R}}^{N} $$ , which comes from a mathematical model for a new tax system proposed in Chile’s 2014 Tax Reform. The system of equations involves a non negative coefficients matrix and

Sustained improvement in student achievement on national standardized tests for low socio economic status (SES) districts is critical for reducing gaps in educational inequality. We report the results of 3 years of implementation of an ICT web-based

This article deals with the numerical approximation of Navier–Stokes equations in a domain with moving boundaries. Using the arbitrary Lagrangian–Eulerian (ALE) method we transform the problem from a moving domain to a fixed reference domain thro

We give a predictive theory of the collisions of a viscous incompressible fluid with solids. The theory is based on interior percussions which account for the very large stresses and contact forces resulting from the kinematic incompatibilities respo

We study the existence and uniqueness of strong solutions for the equations of non-homogeneous asymmetric fluids. We use an iterative approach and we prove that the approximate solutions constructed by this method converge to the strong solution of t

In this article we study supercooling from a macroscopic point of view by modeling the evolution of a supercooled body from its liquid state to its solid state. A first model, which would be expected to have discontinuous solutions, is regularized by

Numerical investigations of unsteady laminar flow and heat transfer in a channel of height H with periodically mounted square bars of height d = 0.2H arranged side by side to the approaching flow have been conducted for different transverse separatio
