Medium of Instruction
Two-way immersion (TWI) is an educational approach that integrates language minority and language majority students for all or most of the day, and provides content instruction and literacy instruction to all students in both languages. Two-way programs typically share the goals of bilingual proficiency, academic achievement, and positive cross-cultural attitudes and behaviors. Students are highly motivated and passionate to study so as to attain higher level education.
TWI is an accumulation of knowledge through repeated practices. Teachers with strong subject knowledge and bilingual abilities design tailor-made materials to guide and motivate students to learn both subject content and target language through different class activities. A typical TWI lesson should contain the following elements:
(1) Teachers use native language (L1) to introduce the topic.
(2) Teachers use target language (L2) to explain and elaborate lessons’ materials. Key
concepts and vocabularies are highlighted.
(3) Chinese and non-Chinese students are grouped to complete the classwork together.
(4) Students share their ideas in front of other classmates.
(5) Teacher summarizes the key points covered in the lesson in native language (L1).
(6) Students are given homework and projects to refresh what they have learnt.
