English Speaking Skills for Higher Achievement

ChatENG gives students the skills they need to take their English speaking to the next level.


Challenges in Korean Education

In an increasingly global world, speaking proficiency in English is of utmost urgency for Korean students. Unfortunately, many Korean children struggle because Confucian classroom culture de-emphasizes complex, real-time speaking in English in favor of lecture and test-taking. While native English speakers are meant to fill that gap, the importance of hiring teachers with specialized training in language acquisition is often overlooked.


ChatENG seeks to solve these issues to give students the skills they need to succeed.


ChatENG Provides a Better Solution

ChatENG teachers are educators with specific training in language acquisition. They all have at least 3 years of experience teaching elementary-age students. That means more effective teaching strategies and faster improvement for students.

Teaching Strategies

ChatENG’s methods are founded in language acquisition research. There are six essential elements included in each ChatENG lesson:


Extended Conversation

Lessons focus on one topic over multiple classes to improve retention and offer many opportunities for genuine conversation with other students, using the teacher as both a model and support.

Student Perspectives

Students engage in authentic dialogue and build relationships with teachers on an individual level, with lessons culminating in a discussion to share their own perspective on a topic.

Instructional Supports

Teachers always model the language, help students practice and utilize sentence frames, virtual reality, images and other visual aids to support student growth.

Small Groups

All ChatENG lessons consist of 7 or fewer students. By keeping the group small, students have more time to talk, and teachers can get to know the individual student’s needs more quickly.

Content Relevance

Lessons are created specifically for the age group being taught and allow for students to reflect on their personal experiences, allowing them to use what they learn in everyday life.

Frequent Assessments

Using interactive technology platforms, teachers evaluate students’ understanding through real-time quizzes, polls, writing, and drawing tools, as well as students’ speech production throughout class.


ChatENG leverages technology to make topics more interactive, engaging and relevant to students. These include:


• Virtual Reality

• Touchscreen drawing

• Interactive Quizzes

• Video
