CDI Survival Guide: Tips for New Teachers (From Real Experience)
(Note: These are experiences shared by me and my coworkers at the Songpa CDI location. Experiences may vary from location to location.)
Welcome to CDI! Working for this part of Creverse is both challenging and incredibly rewarding. While the hours are very different from what you may expect as a teacher, they give you the chance to form close connections with students and coworkers. However, those same hours-and other aspects of the job- can take some getting used to (just like any job).
This guide includes practical tips that helped my coworkers and me survive (and eventually thrive) within the CDI curriculum.
1. Prep Tips for CDI Teachers
Every teacher preps differently, but here are some strategies that consistently work for us:
Keep Your Notes Organized
Some teachers use Google Docs; others use a notebook. I personally use a notebook and highlight key points so I can see everything at a glance. Don’t mind my handwriting 🙂
Start With the End Goal
A great tip from a coworker:
“Focus on the goals you want to accomplish in the class, then work backward. Do the planned tasks achieve that goal?”
This approach keeps your lessons intentional and on track.
2. Classroom Management Tips (Especially for New Teachers)
At our branch, about half the teachers had no experience before joining- myself included. If you’re new to teaching, here are some tools that made a huge difference:
Call-and-Response Activities
Great for getting a distracted class quiet, especially in C2 and V1.
Examples:
Rhythm clapping (my personal go-to)
“Eyes on!” → “Teacher!”
Any call-and-response method you already know.
Hangman/Sharkman Strategy
If a class is disruptive, start drawing a hangman (or sharkman for younger students). Add a piece each time there’s a disruption.
If the drawing is completed before the first or second break, the class loses that break.
This keeps consequences visual, simple, and consistent.
Build Rapport Early
This is one of the most important parts of the job—and one that’s easy to skip because of tight time constraints. But even small moments help.
A quick method:
Ask each student a personal question during attendance.
A student who feels seen is far more likely to listen and participate.
3. Surviving a CDI “Double” (Back-to-Back 3-Hour Class Blocks)
Because CDI teaches upper elementary to lower middle school students, the schedule matches their after-school availability- which means doubles are common. You’ll likely teach one to three of these shifts per term. You will still get hourly breaks, but it will be the same students in one block.
Here’s how to get through them without burning out:
Eat Strategically
Energy crashes make doubles feel twice as long. Eat a solid lunch before your shift, and/or grab something portable for breaks.
I always buy gimbap from a bunsik restaurant because:
It’s quick to eat (you get about 5 minutes)
It doesn’t need refrigeration
It’s surprisingly filling
Caffeine Helps
Coffee or an energy drink can keep you sharp, especially in the second class.
Luckily, coffee is a major thing in Korea, as are energy drinks at every convenient store!
Find Ways to Keep Yourself Engaged
If you’re teaching similar content in both classes, the repetition can get tiring.
Try:
Finding a part of the lesson to nerd out about
Asking students interesting, open-ended questions about the topic
Keeping yourself mentally engaged makes the class more fun for everyone.
4. Understanding CDI Classes: A2, V1, C1, and C2
For an in-depth look into the curriculum, check out our blog- Inside the Smart Classroom at CDIL Curriculum, Methodology, and Technology, but here’s a quick reference!
There are four main course types (The “C” stands for “Capability,” the “A” stands for “Admissions,” and the “V” stands for “Vision!” ):
A2
V1
C1
C2
They’re paired by term:
A2 and V1 occur in the same term
C1 and C2 occur together the following term
Early-week classes are C1 and A2, while V1 and C2 take place later in the week.
A2 and C2: TOEFL-Focused Skills
These levels help students build skills they’ll eventually need for the TOEFL exam—reading, listening, note-taking, answering quickly and accurately, and applying strategies taught in class.
V1 and C1: Discussion, Teamwork, and Projects
V1: Students read two books, participate in discussions, and do a project
C2: Students learn a new concept weekly and discuss it as a class; each lesson includes a project
Both levels emphasize teamwork, critical thinking, and presentation skills.
Working at CDI can sometimes be intense, but it’s also incredibly rewarding once you find your rhythm.
With good prep habits, classroom management tools, and smart double-shift survival strategies, you’ll settle in faster than you think!
