Biography
Jacqueline is an English as an Additional Language (EAL) teacher supporting students in middle school science. She helps students develop the academic language skills they need to succeed in science and across the curriculum.

She is passionate about learning languages and she believes the best way to do this is through intentional and meaningful interactions and practice.

She believes students should be encouraged to engage in thoughtful discussions, structured writing, and collaborative learning experiences that build both linguistic accuracy and critical thinking skills.

Best Teaching Moment
Once, a student told me that she remembered our lessons about coherence and structure during the essay part of the TOEFL test. She thanked me for helping her improve her writing and shared that she got an excellent score.

Moments like that remind me that the skills we practice every day can stay with students long after they have left the classroom. And for me, that is what makes teaching so rewarding.

Shamae Delima

Lab Technician

I am Shamae Ria Delima from the Philippines. I finished my bachelors with the degree BSc in Fisheries from Davao Del Norte State College in my country and have finished the degree MSc in Hydrobiology here in Hungary. I’ve always been fascinated with science, especially laboratory experiments. I am very elated to work with ISD as a Science Technician, letting me gain more experience in laboratory management, experiment and research.
I once worked at Davao Del Norte State College, as an administrative assistant for 2 yrs. before coming to Hungary. I was aiding the program chairpersons of BSc Food Technology, Fisheries, Marine Biology, and Forestry in running the different programs, making sure that all academic and program requirements are up to standards required by accreditation institutions.
IB curriculum is completely different as to what I have first encountered and worked with, but it has really impressed me so much. With this kind of learning, I believe kids can explore, create, discover, and develop themselves through the guidance of their respective teachers to become responsible, confident, and successful adults in the future. IB teaching methods do not just teach students the theories of different academic subjects, they are also teaching them on how to apply these theories in real life situations, helping the students develop critical thinking skills, practical, emotional, and physical skills.

Dr. Eszter Ditrói-Pusker

Hungarian Language and Literature Teacher / Mother Tongue Language Coordinator

My name is Dr. Eszter Ditrói, and I am from Debrecen, Hungary. I have been teaching in this city for more than 10 years, not just in primary and middle schools, but also at the University of Debrecen. During this time, I also taught a Hungarian as a foreign language to students at the Debrecen Summer School. Currently, I am a teacher in the MYP and DP Hungarian Language and Literature and Language A: Literature at the ISD. I continue to teach at the University of Debrecen as a visiting lecturer.
I graduated as a teacher of Hungarian Language and Literature and also have a PhD in Modern Linguistics. I am also qualified as a teacher of ethnography and ethnology and as a museologist. As I was also interested in languages and their structure from a biological point of view: I obtained a BSc in engineering, specialising mainly in biology I have successfully applied the biostatistical knowledge gained here in my PhD work. Later on, I also completed a degree in chemistry (MSc), using this degree and my previous knowledge in museology.
As an educator, I see my role as that teacher, who emphasizes and helps develop each child's understanding of the trans- and interdisciplinarity, which is an essential part of the IB. Besides I highlight this idea in my classes, I’m building up an energetic and understandable learning environment in my classroom. I love to teach children, and I like to show them the different ways of interpreting and understanding the world around them.

Name

Visual Arts Teacher; Media Club Coordinator

I am a photo-based artist who completed his MFA in Photography at Parsons The New School for Design in 2013. For the last five years he has been a teacher of art, design, and digital media at the International School of Myanmar.
Prior to living and working in Myanmar, Tony was a photography teacher in Las Vegas, Denver, and New York City. He currently is making work that makes connections between vernacular photography, social media, futility and desire.

I want my students to be at the forefront of contemporary image-making and digital literacy in order to be reflective users of online platforms. I push my students to be involved in the world of image making in order to engender a criticality about the medium. Whether they are creating content for TikTok, posting to Instagram, or grappling with emerging platforms and applications, they are involved in all facets of digital media. Through studying and making art, students become attuned to complexity; they learn to recognize the cultural choices that underlie even the most mundane moments and actions of everyday life and consider whether these are the choices they themselves wish to make.

My journey led me through nature conservation education before transitioning to mainstream education. Having lived and worked in diverse countries – including Vietnam, South Korea, and the Philippines – I've embraced cultures worldwide.
I have taught many of the major curriculums, but for me I prefer the IB. It offers so much development with the Personal Project, Internal Assessment, Extended EssaY, CAS, ToK and my favorite Service as Action. The IB is a demanding and challenging curriculum, but it produces thoughtful, critical thinking people (teachers and parents/guardians included) to which the world needs.

I undertook my initial studies in general Music and education in the national conservatorium of music in Mexico city.

As a music teacher I have contributed to developing Music departments in international teaching settings and multicultural environments developing Music curricula of international standards, leading extra curricular music activities such as one to one instrumental lessons, orchestras, ensembles, musicals and others, plus encouraging students of diverse musical abilities, and music and non music teachers to participate in the musical life of school.

In addition to this experience I have been a team leader of the MYP and PYP as well as a member of EAL departments contributing to building EAL curriculum simultaneously with the IB .

I have been fortunate enough to work in a number of prestigious international schools, all of which are IB certified. It's been a privilege to work with incredible teachers and students from all over the world. I am delighted and honoured to be expanding my international teaching experience and contributing to building the lSD community.

My international educational experience begins earlier than my professional one as I had the privilege to be a student of the IBDP. This was a wonderful but rigorous experience that opened my mind to the world in an unprecedented way at a young age. It is this experience that made me believe ever since in the IB frameworks; they are of incalculable value for young people. As I have experienced myself, they really are the way to become a lifelong learner, open minded to cultures, as well as a compassionate and thoughtful human being. U believe it develops in students and teachers a will to contribute to the creation of a better and more peaceful world through intercultural understanding, respect and tolerance.

Nationality
Hungarian
Biography
Szilvia Szegedi began her work at ISD teaching German and world literature with the intention of making it not just a subject, but a living experience for her students in grades 6–12. She believes that literature helps us understand ourselves, each other, and the world. She treats her students with empathy and trusts that they will approach the texts with an open mind, because that is how they can achieve true understanding.

Her teaching combines innovation and tradition. She seeks modern methods that create a personal connection with the works and give space for the students’ own questions. The IB approach has reinforced her belief that teaching is not just about transferring knowledge, but also about educating students to think, take responsibility, and be open-minded. Her goal is for her students to become reflective readers who are able to argue, compare different points of view, and recognize human dilemmas. She believes that tradition and innovation reinforce each other in value-based, internationally oriented pedagogical work.

Best Teaching Moment
One of the most defining moments in my teaching career was when one of my students—with great confidence—showed me something they had written, which almost no one had read before. It was a poem that had only been seen by his parents or the silence of his desk drawer. The fact that he asked for my opinion was not only a professional moment for me, but also a deeply human one: a sign that I had succeeded in creating an atmosphere in the classroom where students dared to share their personal thoughts and creations.

In my experience, meaningful learning processes are those that help my students further discover their path and explore their role in a highly complex and ever-changing world. Truly purposeful learning processes are far-reaching and can eventually lead to transformative experiences. I truly value those concept-based educational programmes, such as the IB Continuum, that progress from play-based, through project-based, and culminate in research-based approaches to learning, and that create a culture of high expectations, that is able to meet the needs of each individual learner, in order to help them reach their personal and academic goals, within diverse contexts. I am passionate about the IB, as its programmes on the one hand are founded on methodologies and strategies that foster agency, and on the other hand help students find and make meaning of their learning.

This curiosity continues to shape my work as both a teacher and a researcher.

Currently, I support students in their learning journey as a library assistant and MYP music teacher at the International School of Debrecen.

In the Central European context, it is always challenging how to build on the creative contingency of the present. Therefore, I am fascinated by working together with colleagues to reconceive the boundaries of cultures in a hope to open up possible futures that will best deliver education and social justice.
My journey to become a teacher is not a conventional professional trajectory.I have received my MA in biology and phylosophy, which urged me to continue my studies in sociology, which in turn led to my PhD in educational research. Lately, recognizing the power of stories in our life my attention has been turned to literature and finished English literature and lingusitics at KULeuven, Belgium.
My career to date has been characterized by working in a national framework in the context of elementary, secondary and higher education and a determination to engage in transnational academic dialogues at three universities. The latter I see as an essential element in my formation as a teacher, educational researcher and above all a creative, critical thinker myself.

I completed my undergraduate degree in Psychology at McGill University in Montreal, Quebec. I also completed my teacher training and earned a Master's degree in Special Education in Canada. Additionally, I studied at the Faculty of Education at the University of Illinois at Urbana-Champaign, focusing on Curriculum and Instruction with a specialization in Bilingual Education and English as an Additional Language (EAL).
I have previously taught at international schools in Seoul, Korea, and Ho Chi Minh City, Vietnam. I also gained valuable experience teaching at an independent school in British Columbia, Canada.
My passion lies in supporting students who struggle with learning in English or need additional learning support. I believe that every teacher is a hero or heroine - working tirelessly to uplift their students and empower them to soar like eagles. Teachers are the miracle performers; we are the conquerors who help our students improve and grow in their learning, and the champions who guide our students to become the next generation of history makers.
I am honored to be part of this amazing ISD community. I believe that, as members of ISD, we grow both personally and professionally. We take pride in being part of this community where we support one another to thrive and succeed.
