(日本語は英語の後で) April 1st marked the official start of the CGK Afterschool Advanced Course. The advanced course is from 18:00-19:30 and available to grade 5 students and through Junior High School (consideration will be given to grade 4 students with advanced English skills)✏️ Our first project is student choice and we have decided to research the origin of the legendary Loch Ness Monster and create a timeline of events with the hypothesis that it is a myth and not a fact🗓 Student choice allows students to follow their own interests and build their research, critical thinking, and debate, and language skills in a way they decide. For more information about the Afterschool Advanced Course please feel free to get in touch😊4月1日、CGKアフタースクールのアドバンス(上級)コースが正式にスタートしました。アドバンスコースは18:00-19:30で、5年生から中学生までが対象です✏️(英語力の高い4年生には配慮します)最初のプロジェクトは生徒の選択制で、伝説のネス湖の怪物の起源を調査し、事実ではなく神話であるという仮説のもと、年表を作成することにしました🗓生徒が選択権を持つことで、生徒たちは自分の興味に従いながら、リサーチ力、批判的思考力、ディベート力、言語能力を身につけることができます。アフタースクール・アドバンス・コースの詳細については、お気軽にお問い合わせください😊#afterschool #afterschoolyokohama #アフタースクール #英語学童 #探究活動 #インターナショナルスクール #横浜 #インターナショナルスクール横浜 #internationalschool #cgkis #英語上級 #英語アドバンスコース
