π I am Lee Yu-jeong (Charlie), your English learning mentor. I am an English education expert with global practical experience, having graduated from California State University, Northridge, and worked as a Radiologic Technologist at a local hospital in the United States. Since returning to Korea, I have served as the director of a language academy, systematically teaching all areas of English (reading, writing, grammar, and speaking) to elementary and middle school students. I have also concurrently held a role overseeing overall educational operations, including teaching conversational English and writing, recruiting native instructors, and managing the curriculum. π₯ In the classroom, I discovered that many students share a common limitation: while they are comfortable with problem-solving, they struggle with simple writing and speaking. Therefore, my core educational philosophy is to organize grammar concepts from an "understanding-centered" perspective and then naturally connect them to writing and speaking. πͺ Currently, I am supporting students' growth as an English mentor who guides them to learn English as a βlanguage for thinking and expressingβ through integrated classes in reading, writing, and grammar; critical thinking classes based on TED talks and native content; and conversation classes focused on practical use through everyday English. π English is a language where continuity, consistency, and enjoyment are more important than short-term results. <Features of Teacher Lee Yu-jeongβs Classes> π Personalized, level-appropriate instruction tailored to the student's level π Understanding-centered grammar classes that naturally connect with elementary and middle school writing π Level-based reading classes to build literacy (AR Β· Lexile-based) π Key point classes reflecting middle school exam trends π Critical and logical thinking classes utilizing TED talks and native content π Presentation of individual learning roadmaps based on elementary and middle school level tests (Setting direction for AR Β· Lexile Β· school exam preparation) π College admissions consulting and career planning guidance for prospective high school students

I heard that there are many talented teachers on Kookge, so I did my best to search and signed up for classes. At first, I thought a 40-minute class might be too short, but I was foolish to think so. When the first class started, I was shocked, thinking, "Wow, has there ever been a class where you can focus this much?" My child couldn't waste a single minute during those 40 minutes. Focus, focus, focus!! I was debating whether to enroll in a special academy course or Kookge this vacation, but I ended up signing up and now I wonder why I even hesitated. I was deeply moved by the class's quality, and the homework corrections were so meticulous. So, I searched for Teacher Lee Yu-jeong's classes and signed up for two more. It's just a shame that this review is limited to 300 characters.

Thank you so much for your heartfelt review π As the one who prepared the class, every single sentence gives me great strength. π I designed the lessons with the goal of ensuring uninterrupted focus, understanding, and application so that the time does not feel short. Hearing that you personally experienced your child's immersion makes me feel a great sense of reward. When editing assignments, I also prioritize whether the material can be immediately applied to middle school assignments and actual writing. π

You explained everything clearly, kindly, and in an easy-to-understand manner. Even though it was an online Zoom class, you calmly guided my child to keep them focused through the screen, and repeated explanations for parts they didn't understand, allowing my child to follow along with the lesson with enjoyment. I particularly appreciated that you explained difficult words using examples tailored to my child's level and encouraged them to read and speak on their own. My satisfaction was so high that even after class, my child said, "It was fun because you explained it easily!" Thanks to the kind explanations and warm feedback tailored to my child's level, my child has also gained confidence in reading.

Thank you so much for your valuable feedback. Since online classes can be difficult to concentrate on, it is a huge source of strength to hear that your child participated happily and said, "It was fun because you explained it easily." I will continue to work calmly and kindly with you so that reading can be perceived as a "fun experience" rather than a burden.ππ Thank you sincerely for leaving such a warm review π

Thank you for opening the class, even though there is only one student. My biggest concern was English classes for my child, who is entering middle school. Since I didn't know my child's level, I was worried about which course to take. Just then, Ms. Lee Yu-jeong opened a Basic Middle School English Grammar class, so I was able to enroll. I was worried about whether my child would be able to keep up with the class because I didn't know their level, but I felt proud seeing them do the homework on their own right after class. Ms. Lee Yu-jeong's message of encouragement right after class, saying that it is difficult but they will do well in the future, also gives me strength. Thank you.

Thank you so much for leaving a review. I know you must have been worried at first because it is difficult to accurately assess your child's level, but your trust in entrusting the lessons to me gave me even more strength. Hearing that you saw your child taking care of homework on their own immediately after the first lesson makes me realize just how great our student's potential and capabilities are. I will continue to conduct lessons that build a solid foundation from the basics so that the child does not lose the confidence that "it is difficult, but I can do it." I will also sincerely cheer for your growth. Thank you once again for your valuable words. ππ
