SHANGHAI, July 18, 2019 /PRNewswire/ -- Recently, British
Council, UK's international organization for cultural relations and
educational opportunities, and Centre for Research in English
Language Learning and Assessment (CRELLA) of University of
Bedfordshire, a leading research
center in the areas of language proficiency and language
assessment, have released a joint research study titled Language
learning gains among users of English Liulishuo.
The study indicates that after
an average of 36.88 hours study with English Liulishuo, an
AI-powered English learning mobile app, the flagship product of
LAIX Inc. (NYSE: LAIX), 72% of participants improved their test
scores, with about 40% of participants progressing at least to the
next higher level of the Common European Framework of Reference for
Languages (CEFR), guideline used to describe achievements of
learners of foreign languages across Europe.
The study investigated improvements in English language ability
among 746 users of English Liulishuo app, taking courses at three
levels over a period of approximately two months.
To evaluate the influences of an
AI teacher on English proficiency accurately and efficiently, Aptis
test, a global English assessment tool developed by the British
Council, was employed in the study. All participants were
registered to take one British Council Aptis test shortly before
the beginning of their course and another shortly after the
end.
The Aptis test measures across
grammar, vocabulary, speaking, listening, reading and writing
abilities of candidates. Candidates can correspond their Aptis test
results with China's Standard of
English Language Ability (CSE), evaluation scale for English
language ability issued by China's
Ministry of Education and the State Language Commission, and Common
European Framework of Reference for Languages (CEFR).
The study result indicates users
who used English Liulishuo alone demonstrated more than 10 times
higher language learning rates than those adopting other study
approaches in addition to using English Liulishuo (0.324 versus
0.03). A data set of 559 users
shows an average overall Aptis score gain of 0.324 points per hour
of English Liulishuo study. Users usually made the greatest
improvements in their reading and speaking skills.
The result also proves English
Liulishuo's popularity among users. According to the study, "almost
90% stated they had enjoyed studying with the app and that they
planned to use English Liulishuo in the future. Over 80% believed
that it was more effective than other ways in which they had
studied English."
"This is the most significant development in the area of
auto-scoring that I have seen in the past twenty years. Your
(English Liulishuo) technology has a clear and distinct lead over
any current solution and has multiple areas of potential expansion
in language learning and even more especially in language
assessment," said Professor Barry
O'Sullivan, Head of Assessment Research & Development at
British Council, Founding resident of the UK Association of
Language Testing and Assessment (UKALTA) in previous occasions.
Launched on February 14, 2013,
English Liulishuo App integrates LAIX's proprietary speech
recognition engine, auto-scoring engine and adaptive learning
system, and combines a comprehensive suite of courses. The App also
has additional features designed to enhance the user experience and
drive user engagement. The course is rich in content and form,
including scene dialogues, authentic pronunciation lessons and
courses customized by AI English teacher. The product employs
gamified role-playing, scoring and smashing, which leads a new
trend of "gamified learning" in Chinese online English
education.
On April 2, 2019, English
Liulishuo's proprietary AI placement test system was approved by
China's Standard of English
Language Ability (CSE), which makes LAIX the first company in
China to join CSE. The placement
test system has helped nearly 40 million users to
complete their English level grading. It is worth noting that
to enhance the overall grading accuracy, the system employs
improved Angoff method, which engages one more discussion and
judgment step than the traditional one.
