Christopher Hayward


Bachelor Of Science (Applied Mathematics)
Professional Graduate Diploma in Education (Secondary)

Having grown up in an international school and having always enjoyed mathematics, sharing my passion for the subject with others lead me to teaching. I completed an undergraduate degree in Applied Mathematics and subsequently teacher training and then enjoyed a range of experiences teaching in Scotland. The international pull grew stronger and I moved with my wife to Brunei. During an enriching eight years there I became Head of Department and subsequently Assistant Head, gaining experience with the IBDP Programme.

Moving on as a family of four, the opportunities of a vibrant city and new challenges brought us to Singapore and the ISS community became our home.

Working closely with students and seeing them grow through their school life and learning from their experiences gives me enormous pleasure. I strive to see students leaving school as strong individuals confident in their own abilities and able to work collaboratively with others.

Kindergarten Teacher

Bachelor Of Arts (Primary Education: Ages 3-11)
Qualified Teaching Status

Originally I am from the United States, however, I grew up here in Singapore! I am an alumnus from ISS International School and this is my first year at ISS as a classroom teacher. I am so grateful to have the opportunity to teach at the school that gave so much to me.

I strongly believe in the value of outdoor and inquiry-based learning. My aim is to create an environment where the children can feel safe, valued and therefore ready to learn. A goal for me is always to instil a love of learning right from the very start. I believe that when children are having fun, the skills they learn will translate to all areas of life. I also believe that when children love to learn, it creates a culture of lifelong learning.


Yvonne Hayward

Grade 1 Teacher

Bachelor of Education (Hons)

I am a global citizen; my nationality is Scottish, I spent 15 years of my childhood in Pakistan, where I was educated at an International School, and I have a home in a lovely village in England. After studying primary teaching, in Scotland, I taught in the lower primary for four years. I then moved to Brunei and taught for a further eight years in a variety of age groups.

I value each child in my class as an individual with unique strengths and varied learning styles. I am committed to providing each child in my care with relevant and meaningful learning experiences where we enquire about the word we live in and how we can all become more responsible global citizens. I am passionate about sustainability and educating children at an early age about choices they make which can have a positive impact on our planet.

Grade 2 Teacher

Bachelor Of Arts (International Development Studies)
Certificate in Diversified Liberal Arts
Master Of Education (Cross-Cultural Language and Academic Development)

I believe that all students arrive in the classroom with individual strengths and varying learning modalities. It is my job as the teacher to facilitate student learning by capitalising on their innate sense of wonder and discovery.  Having had the opportunity to grow up on two different continents, I view diversity as a source of strength in education.  Every classroom is a place where students discover their own agency and cultivate their identities as artists, authors, scientists, and mathematicians.  As a life-long learner, I look forward to growing and discovering alongside my students at ISS.


Sophie Crawshaw

Grade 3 Teacher

Post Graduate Certificate in Education (Primary)
Bachelor of Arts (Hons) Jurisprudence

I am originally from Northern Ireland and have taught in London, Shanghai and Singapore.

What I enjoy most about teaching is the collaborative environment that schools nurture. With class-mates, friends, peers and the wider school community there is a shared goal of discovering the world around us and learning together. Of trying new things, achieving new goals, celebrating successes and persevering when something is tricky. Everyone in school is heading in the same direction, cheering on the person beside them in a happy, safe and secure environment.


Vanessa Adamberry

Grade 4 Teacher & K-12 Feedback and Assessment Coordinator

Bachelor of Education
M.Ed student in Advanced Teaching

My teaching career began 15 years ago in Sydney, Australia teaching Grade 1. Since then, I have taught in both Sydney and Singapore across a range of different elementary grades and also as a SEN teacher. I have been teaching the IB PYP framework for over 10 years and I am currently pursuing my Masters of Education in Advanced Teaching. This is my second time living in Singapore having previously taught here between 2008 and 2014. This time I am here with my two children and my husband who graduated from ISS in 1999.

I believe in the importance of instilling a love of learning in all of my students and am an advocate for learner agency and the promotion of inquiry-based learning.


Anjana Dayal

Grade 5 Teacher & PYP Global Citizenship Coordinator

Master of Science (Education)

I have been fortunate to have worked with some amazing individuals who have guided me and transmitted their passion for teaching throughout my teaching career. Since my teaching career began in 2004, I have continued to learn and grow with my students year after year. I would have to say that teaching the Grade 5 exhibition in my previous school was a key moment in my teaching career as I was able to see a specific group of students really take charge of their own inquiry and bring forth action in their community. The entire exhibition process that year was a learning experience for all the students and teachers involved, and a celebration well deserved for the school community.


Shagun Batlaw

Grade 5 Teacher & PYP Numeracy Coordinator

Master in Teaching, USA

It is frequently believed that some teachers leave a mark on their students. In my case, every batch of students has brought a memorable experience. Learning is a life-long process and I have learnt something new from every group of students that I have taught, whether it was in the public school system in America or in international schools in Singapore. I love the interaction with my students. They make me smile and occasionally take my breath away with the clarity of their thoughts. I suppose being a mother to two teenagers helps because I love to be in their company. We connect our learning with current news events around the world, and this is a topic close to my heart. There is nothing more satisfying than watching my students’ learning curve.

Patty Winpenny

Learning Support Coordinator

Master of Education (Special Education)
Master of Arts (Soviet and East European Political Economics)
Bachelor of Arts (Russian Language and Literature)

My teaching career began with languages and travel. I directed US-USSR programs: CIEE’s College Exchange, Children’s Art Exchange, and Citizen Exchange Council educational trips. As a learning specialist in Vermont, I coordinated services with therapists, speech language pathologists, and neurologists. Wanderlust brought me to Asia, and years in Shanghai deepened my resolve to engage students with diverse challenges in inclusive environments.

Discovering meditation through tragedy (widowed and losing a son), I am grateful for life’s gifts. One son is an engineer, married to a Russian dancer; the other is a commercial beekeeper in Hawaii, married to a teacher. Joy is winter holidays with grandchildren in Hawaii and summers together on our Vermont farm.

Cyclist, swimmer, kayaker, skier, Pilates enthusiast, and dancer, I believe in the transformative power of wellness to help us achieve our best. An optimist, I consider myself a teacher diplomat, and am honored to work at ISS.

Being an educator for 11 years in Singapore, I had the opportunity to work with different groups of children ranging from toddlers to elementary school students. When I am working with my students, I enjoy helping them to reach for their dreams and potential. With my interest in art and dance, I love sharing these aspects of my Chinese culture with everyone I am working with as we live in a diverse society where every should learn to child feel valued and treated with respect.

It is an exciting new journey for me to join ISS International School where I would be able to build on my learning journey as an educator in one of the most established international school in Singapore.


Hima Venkateswaran

PYP Multiple Literacies Coordinator, MYP Science and MYP Visual Arts Teacher

Master of Education (Early Childhood Education)
Bachelor of Science (Chemistry & Biology)
Specialist Diploma in Early Childhood Education & Leadership

I am excited to be teaching Art and Design this year, my eleventh year at ISS. I have been privileged to teach Kindergarten and then Grade One in the past years and now I have this great opportunity to pursue my passion for Visual Arts and Design. I believe students should be invited to think deeply about an artwork, engage at the aesthetic, emotional and intellectual levels and apply the elements and principles of art and design in their work. Art is a language, an expression and a powerful means of communicating with the world. It is self-expression that can be represented through myriad mediums and interpreted in multitude ways. My passion for the arts has always made it an integral part of my teaching practice. Art and design transcend across the curriculum and I look forward to making these connections with the students.

Christi Davis

Music Teacher

Bachelor Of Arts(Music)
Bachelors Of Arts (German)
Master Of Music Education

Hello from Christi Davis!  I have been a music educator for over 30 years. While raising my family, I taught at the same school for 20 years. I am now enjoying teaching internationally, having done summer camps in Poland and full time in Bangkok. My main instruments I play are clarinet, saxophone, recorder and some ukulele. My concentration of study was vocal music and conducting.

I believe that all children deserve a well-rounded music education that gives hands-on experiences in singing, playing instruments, moving to music and viewing and participating in musical programs.  I want my students to learn about excellence, empathy and enjoyment through music. Music takes you on an adventure:  through time periods, traveling among cultures, creating your own music, and sharing music with others. Through music, you can learn discipline,  gain confidence and  be a part of a larger whole. 

I am very blessed and excited to be a part of the ISS family and I look forward to getting to know you and make music with you.

English Language Support Teacher

Bachelor of Arts (Economics / Sociology)
Bachelor of Education
Post-Graduate Diploma (Management of Learning Disorders)
TESOL Certificate
Member of the SENIA Board (Special Education Needs & Inclusion Association) Singapore Chapter

There is nothing quite like teaching. Each learner, each class, each day is unique. I have been fortunate to have had the opportunity to work in a wide spectrum of educational settings. I began my career In Mumbai, India, as a Primary school teacher. Exploring other avenues, I worked with teams, producing English texts for Primary schools and interactive content for teachers to use in Government schools. The move to Singapore provided the opportunity to work in international schools and to teach the PYP curriculum. In schools, and in workshops I’ve attended, I have been fortunate to collaborate with wonderful educators and gain fresh perspectives on teaching and learning.

Once home, I de-stress by walking my retrievers, maintaining my plants and reading. My family love to travel and we try to find places, off the beaten track.

I am originally from Turkey and have been living in Singapore since 1994. I have a vast experience on third culture kids who live in different countries throughout their education lives due to the expatriate life requirements.

My interest in education and students well being derives from curiosity and hunger that I have felt, to make them achieve their best potential and to provide them a conducive environment to do so. I believe every student has equal chance and right for education, no matter what the difficulties they are facing.

I have years of experience working with children and adolescents with special needs and my lifetime goal is to reach out to those who have difficulties and help them along the way by providing a support with a holistic approach that they rightfully need.

I have 2 wonderful teenagers who are continuously helping me to be the best I can.
