Abstract
The project adopts three different treatments aimed at improving students’ learning in rural areas in China. The first treatment provides students "live" instruction online from a highly qualified teacher, the second treatment provides students with pre-recorded, and the third treatment provides teachers and students with teaching resources, teaching plans, short videos and other related teaching materials of urban excellent teachers. This project aims to compare the effects of the three interventions relative to the control group.

Experimental Design

Experimental Design
The project adopts three different treatments aimed at improving students’ English learning in rural areas in China. The first treatment provides students "live" instruction online from a highly qualified teacher, the second treatment provides students with pre-recorded, and the third treatment provides teachers and students with teaching resources, teaching plans, short videos and other related teaching materials of urban excellent teachers. In each treatment group, online instructors/project managers work with local teachers and dual-teacher links are forged to improve rural students’ English learning.
By cooperating with provincial education department in Gansu Province, we are able to carry out the trial in three prefectures and cover 200 rural schools. In each school, one class in Grade 3 and one in Grade 4 are randomly drawn to produce the final sample. An education foundation, sponsored by a top education company in China, provides intervention courses/materials to treatment schools for free and support the daily project management.
