MetaMetrics Partners With Youdao to Integrate Lexile WordBank Into China’s Leading Kids Dictionary

English language learners in China will develop and grow vocabulary with resources from WordBank   

DURHAM, North Carolina and BEIJING, China April 23, 2020 – MetaMetrics® announced today that it is partnering with Youdao, Inc., a leading intelligent learning company in China, to integrate its Lexile® WordBank into China’s leading online dictionary designed for children, Youdao Kids Dictionary app. Now, as a result of this global partnership, Chinese primary students learning English can develop and grow their vocabulary. Youdao Kids Dictionary is a popular online dictionary, providing Chinese and English language content and intelligent-learning services for primary school students.

Youdao CEO Feng Zhou said, “We are quite delighted to partner with Lexile WordBank. We always seek to provide the authoritative content for Chinese kids on their way of language learning. ”

To build strong English language skills, it is necessary to develop a rich vocabulary. The Lexile WordBank includes more than 50,000 words from the top K-12 textbook programs, all published since 2011. The WordBank contains recent and relevant vocabulary, unlike other databases available today that were developed from out-of-date resources or texts intended for adults. The vocabulary in the WordBank spans the K-12 curriculum, including words from science, math, social studies and general vocabulary words, and is searchable by grade level and subject. It allows curriculum and assessment developers to transform vocabulary instruction by ensuring that their products and assessments contain the words students need to know when and where they encounter them.

“The learning experts at Youdao recognize that building a strong vocabulary is critical to becoming proficient in English,” said Malbert Smith, CEO and co-founder of MetaMetrics.

“We are proud to partner with them to include our WordBank in their new Youdao Kids Dictionary vocabulary app.”

Using the Lexile WordBank, curriculum and assessment developers can identify where and when students will likely encounter words in their school reading and prioritize a subset of high-value words for a specific purpose. For example, using the Lexile WordBank, curriculum and assessment developers can answer questions, such as in what grade do students typically first encounter a specific word or what are the science vocabulary words a fourth-grade student should know.
