Geography

Layal Maallawi

I am a Geography teacher with 15 years of experience, currently teaching at Maroun Abboud Public High School – Aley and Abadiyeh Public High School, and hold a Master’s degree in Geography from the Lebanese University. My professional development includes a Diploma in Total Quality Management, specialized training in surveying at the Meteorological Department of the Directorate General of Civil Aviation, as well as training in Google Earth Engine, data analysis, and artificial intelligence in education. I integrate GIS, programming, artificial intelligence, and data analysis within STEAM to develop critical thinking, creativity, and problem-solving skills. I received the STEAM Teacher of the Year Award in 2019 and the STEAM Excellence Award in 2025, which gave me the opportunity to participate in BETT London 2026. I have also supervised projects that earned medals at the Science Fair. I believe in continuous learning and in the power of geography to help students understand the world and create meaningful impact.

Sociology

Darine El mohtare

Sociology teacher at Hussein Massoud Public High School – Bchamoun, Maroun Abboud Public High School – Aley, and Saint Joseph High School – Shweifat.

I believe that every student has their own way of being creative, and giving students motivation through encouragement, effective communication, and allowing them space to freely express their opinions leads them to success. I hold a Master's degree in Family Sociology from the Lebanese University, I am continuing my studies to earn a Master's in School Counseling from the Lebanese University.

Geography

Siham Al Danaf

She holds a Licence in Geography from the Lebanese University and has extensive research experience examining the impact of climate change on the extinction of marine and terrestrial wildlife in Lebanon. Her approach goes beyond presenting geography as a theoretical subject, instead introducing it as a practical and scientific field that helps students understand the world around them. Through topics such as atmospheric pressure, geology, time and temperature, latitude and longitude, and the Earth’s internal structure and layers, she encourages students to explore how and why natural phenomena occur. She places particular emphasis on developing students’ critical thinking and scientific reasoning, while helping them connect theoretical concepts with real-world observations.

Arabic

ستّ الكلّ رياض ضوّ

أستاذة اللّغة العربيّة وآدابها في ثانويّة مارون عبّود الرّسميّة -عاليه- منذ زهاء ستّة وعشرينَ عامًا، وحاصلة على شهادة الماجستير في الاختصاص من الجامعة اللّبنانيّة. شغلتُ موقع منسّقة المادّة قرابة سبع سنوات، حرصتُ خلالها -وما زلتُ- على متابعة التّلاميذ وتفعيل مشاركتهم في النّشاطات والمسابقات الثّقافية والأدبيّة.
وبما أنّني أحمل أمانة لغة الضّاد، فإنّ هدفي المرافق لرسالتي في التّعليم، هو غرس محبّة اللّغة العربيّة في قلوب التّلاميذ ليتقرّبوا منها ويبدعوا فيها، بعد أن باتت تعاني من هجر أبنائها لها. لذلك أحاول جاهدة تحويل حصص اللّغة العربيّة إلى حصص تفاعليّة بعيدة عن التّلقين، لتمكين التّلاميذ من إتقان المهارات المطلوبة، عبر تذوّق جماليّات لغتهم وربطها بواقعهم وأفكارهم، حتّى يعبّروا من خلالها عن عالمهم المعاصر.
