What is EALS?
EALS is an English adaptive learning system with a database containing questions at different levels of difficulty for English learners at varying levels based on a series of English MOOCs developed by Tsinghua University. With the key information technologies, such as machine learning and big data analysis, it can provide the learners with individualized learning plans designed from the analysis of their learning record, enabling them to improve their English more efficiently in a way of entertainment.
How does EALS work?
EALS consists of two subsystems: learning system and vocabulary system.
The learning system, designed and developed by PhD candidates from the Department of Computer Science and Technology at Tsinghua, is divided into 4 modules: leaner record analysis, vocabulary learning, vocabulary testing, and rewarding. The vocabulary system, designed and developed by the professor and post-graduate student from the Department of Foreign Languages and Literatures at Tsinghua, has a custom database containing words in different fields and disciplines at different levels in reference to CEFR (Common European Framework of Reference), in which the words are presented with its definition, collocations, example sentences as well as the videos, taken from two MOOCs for review and consolidation. The learning activities in the MOOCs will facilitate their English learning, while learners’ frequent test results will gear them to different tasks, which is expected to adjust according to his or her progress. The authentic examples in the MOOCs are shot to demonstrate the contexts where the words may be used in daily communication.
What’s special in EALS?
EALS automatically suggest the appropriate English words they need to learn according to the dynamic English proficiency. It starts by giving questions at the level chosen by learners, based on their performances, assigns them an approximate starting level with corresponding MOOCs for consolidation. Learners then determine a more exact level for themselves as they play. During the whole learning process, learners can accumulate points which decide what kinds of gifts they may earn, which is designed for the learners from the poverty-stricken area for educational poverty alleviation, especially for the children.
