Project Title: Realizing children’s potential in language development: input and intervention 「發揮兒童在語言發展中的潛力:輸入和干預」

由2018年至2020年, 兒童雙語研究中心跟劍橋大學-香港中文大學雙語研究聯合實驗室開展了一個名為「實現兒童在語言發展中的潛力:輸入和干預」的研究項目。

From 2018 to 2020, Childhood Bilingualism Research Centre (CBRC) and University of Cambridge – Chinese University of Hong Kong Joint Laboratory for Bilingualism carried out a project titled “Realizing children’s potential in language development: input and intervention”.


Why is language learning in early childhood so important?


Learning one or more languages in early childhood fosters children’s development in various ways:


Socioeconomic Status and Childhood Language Development


We have found that children from low SES families receive less language input than those from high SES families. Such children from low SES families are vulnerable to language delay due to impoverished input.


Language intervention: helping children from low socioeconomic status families


This project aims to address a societal problem among underprivileged children and promotes equal opportunity for language learning in Cantonese and English. Three objectives have been established:

研究對象 Participants


More than 160 students and parents volunteered to participate in this study. They were from two kindergartens: Po Leung Kuk Ng Tor Tai Kindergarten and Po Leung Kuk Mrs. Chao King Lin Kindergarten.

研究團隊 Our research team  


Researchers administered tests to students, including vocabulary and grammar in both Cantonese and English as well as tests of  memory and intelligence. The tests were conducted in a one-on-one question and answer format. The research methods and materials used in this research were approved by Survey and Behavioral Research Ethics (SBRE) at CUHK.

中文大學兒童雙語研究中心自行研發了一個語言干預計劃,名為「聼故事學英語」課程。 接著連續十星期,學童在家長的引導下觀看英語故事短片,並就故事進行討論交流,以增加學童接觸優質英語的機會,提升學童的英語詞彚量、聆聽及說話能力。

An intervention program, “Learning English through Stories” was developed by CBRC. Over a 10 week period, students watched short story videos in English and participated in follow-up discussions under the guidance of their parents to increase their exposure to high-quality English input, and to improve their English vocabulary, listening and speaking ability.


After the 10 week intervention program, the research team returned to the school to conduct a post-test to assess children’s English proficiency. The story vocabulary test was developed by the KPF project team to assess children’s expressive vocabulary. The vocabulary was selected from the Englishstory videos watched by the children.


After analyzing the data, the researchers visited both kindergartens to explain the findings to the principals and teachers, and made suggestions to improve the language curriculum.

兩次到校測試結果顯示,有參與「聼故事學英語」課程計劃的學童 (實驗組)在故事詞彙測試中,比沒有參與「聼故事學英語」課程計劃的學童 (控制組)有較為顯著的進步 (p = .069)。

The results of the pre-test and post-test show that students who participated in the “Learn English through Stories” intervention program (i.e., experimental group) demonstrated greater improvement (p=.069) in the story vocabulary test compared to those who did not participate in the course (i.e. control group).

總共有48位家長於「聼故事學英語」課程計劃結束後填寫了語言環境調查問卷,而問卷結果顯示大部分家長都認為子女於參與計劃後,對英語的態度有正面的轉變。例如:他們更喜愛閱讀及聽英語故事、看英語電視節目、玩英語Apps 等。

A total of 48 parents filled out the language environment questionnaire after the “Learn English through Stories” intervention program ended. The results of the questionnaire showed that most parents noted that their children’s attitude towards English had changed positively after they participated in the program. For instance, the children show more interests in reading and listening to English stories, watching English TV shows, playing with English apps, etc.






Children in the sensitive period of language development are good at learning language provided that they have access to rich input.

Our research shows that ten weeks of “input intervention” in the form of English story videos, with the addition of a few interactive elements, can bring positive effects on children’s English learning. Children’s interest and attitude towards learning English have been greatly improved, which is also reflected in their test scores.

It is important for parents and teachers to create an input-rich environment for children to enjoy high-quality language input. High-quality language input that is rich and diverse in vocabulary and expressions can attract children’s attention. Equally important is to ensure the input providers’ pronunciation and grammar is accurate and native-like.

The intervention program that provides high quality online materials is an effective and low-cost way to supplement and boost children’s language input as children might not have access to the sufficient high quality input at home or school.
