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 third year at ISS as a faculty member. 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.

Music Teacher

Bachelor of Arts (Music)
Bachelor 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.

Grade 4 Teacher

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.

English Acquisition Teacher

Master of Arts (Applied Linguistics)
Postgraduate Diploma (Applied Linguistics)
Postgraduate Certificate (Education)
Diploma (Teacher English to Speakers of Other Languages)
Bachelor of Science (Metallurgical Engineering)

Originally from the Philippines, I made Singapore my second home in 2005. This change of home base created a shift in my profession as well – from being a metallurgical engineer to becoming an English language teacher. More than a decade after making that career switch, I am glad I made that choice.

I have been teaching ESL for more than 10 years. Doing further studies in the field has equipped me with knowledge about theoretical underpinnings and these bases have greatly informed my teaching practices. While space won’t allow me to discuss my teaching philosophy in detail, two of the theories that have significant influence are Vygotsky’s socio-cultural theory and Halliday’s Systemic Functional Linguistics (SFL). Understanding Vygotsky’s concept of ZPD (Zone of Proximal Development), I employ scaffolding, modelling, and collaborative learning strategies in my classes. Halliday’s SFL framework, on the other hand, arms me with a powerful lens in highlighting the role of language in learning “school” content. This is critical in helping learners become aware of the different linguistic choices that construe varied types of meanings in different social contexts.

Subscribing to the belief that ‘all lessons are language lessons’, I find SFL’s grammar as a meaning making resource powerful in providing a way to identify the grammatical and linguistic features of a text, which results in a more explicit focus on language in teaching different subjects such as Science.

Outside of the classroom, I enjoy singing, cooking, and playing basketball.

English Language Support Teacher

Diploma in Teaching English to Speakers of Other Languages
JLPT (Japanese Level Proficiency Test) Level 3

I was born in Indonesia, grew up in Singapore and lived in Japan for 12 years before returning to Singapore in 1992. Consequently I learned to speak Japanese in addition to English, Indonesian and Mandarin. The beginning of my career as an ESL teacher began in Japan in 1983 where I taught English to Japanese students as young as 3 years old and retirees who chose to learn English language as a hobby.

The opportunity to teach came again when the Singapore Japanese Secondary School (SJSS) had an opening for an ESL teacher. After 2 years at SJSS, another opportunity was given to me at an international school where I was a homeroom and English teacher for 5 years. Apart from going to the movies, I love cooking, handicraft and gardening though we don’t have land to grow vegetables here in the urban city of Singapore.

ESL Specialist

Bachelor of Business Management
Diploma in Teaching English to Speakers of Other Languages (TESOL)
Certificate in Teaching International English Language Testing System (IELTS)

My passion for teaching started from a young age when I was often asked what I wanted to be when I grew up. After a brief working experience in the financial industry , I realised that only teaching could bring me the satisfaction and motivation I was looking for. Over the years, I have taught toddlers right up to high school students from various cultural backgrounds. When they thank me for providing them with the knowledge and support they look for, that motivates me to do better. With my experience, I hope to work towards the total development of the students and instil an appreciation for English. Outside the classroom, I love travelling and spending time with my family.
