These are notes of a talk given at the probability student seminar in the Weizmann institute of science on September 2011. After introducing Galton-Watson branching process, we consider conditions for which the process survives forever and for which it has a binary tree as a subtree with the same root. As an application, Mandelbrot’s fractal percolation model is discussed.

These are notes from the (ongoing) Student Seminar on Geometry of Fundamental Lemmas at Columbia University in Fall 2017, which is organized by Chao Li, Yihang Zhu and myself. A program with more detailed information, written by Chao and Yihang, can be found here.

In this paper, we describe the results of the first large-scale study, based on a unique data set from North Carolina, assessing the relationship between the certification of teachers by the National Board for Professional Teaching Standards (NBPTS) and elementarylevel student achievement. Our findings indicate that NBPTS is successfully identifying the more effective teachers among applicants,...

Interaction plays an important role to the success of distance learning. As most distance learning environments utilize mainly asynchronous ComputerMediated Communication (CMC) systems, interaction research that focuses on synchronous CMC is largely ignored. This study scrutinize the patterns of learnerlearner interaction in a distance-learning environment. Student interactions in synchronous a...

The Center has over 125 Stanford University faculty affiliates, national and international fellows, student affiliates, and visiting scholars and fellows. These affiliates and fellows are engaged in core research on trends in poverty and inequality, the sources of poverty and inequality, the consequences of poverty and inequality, and the effects of policy initiatives on poverty and inequality....

Understanding the impact of these contextual factors on students' perception of teaching performance may help to further understand seminar teaching. Besides that, it ...
