Use of technology in the classroom

ISL is proud that students and faculty benefit from a technology-rich learning environment which provides:
- 1:1 iPads per class in G3-G5, and shared iPads in EC to G2. iPads offer a rich way of learning, assisting in the collection of work samples and experiences, and creation of digital portfolios. They provide apps for film creation, news reading and animation; G3-5 also benefit from 1:1 iPad keyboards to assist with typing skills.
- Ebooks and audio books to read along with those borrowed from the library
- Science labs with modern data logging equipment, including portable digital colorimeters and high precision balances and a range of sensors (eg: temperature, pH, CO2, forces) to allow students to accurately record, visualise and export data
- 1:1 laptops for Grades 6-7. Students take their school laptop home to bridge the gap between home learning and school learning, and to give students the opportunity to develop responsibility for their tech.
- Interactive whiteboards and projection devices in classrooms to support sharing and collaboration
- Suite of Microsoft Apps for Education to create projects that support their units of inquiry
- Students have the opportunity to develop their creativity through the use of our annual licences for Adobe Creative Cloud (digital design package), as well as Google Sketchup Pro

A dedicated space for students to learn real life skills using:
• News Broadcasting equipment and use of the green screen

Qualities and characteristics best defining the school

ISL provides an intercultural community that fosters a passion and enthusiasm for learning through outstanding educational practices, recognised by OFSTED, the IB and CIS.
At ISL, everything we design encourages students, teachers and parents to use the diverse cultures, languages and viewpoints around them to change the world for the better. Students' cultural and linguistic identities are valued and nurtured through our international curriculum and Mother Tongue programme.
Since 1972, we’ve established a community where students, parents and staff are happy and engaged in school life. That’s why our people are curious, able to explore deeper and broader, and build a unique understanding of the world around them. They develop deeper thinking and share rich experiences that send them out into the world with the talent, determination and compassion to change it for the better.

ISL offers an exceptional world of learning for every student. Starting with a genuinely warm welcome to its multicultural environment, ISL works with each child to devise an individual learning programme tailored to their unique needs and goals. ISL's strong focus on student wellbeing, in a supportive environment, is complemented in the classroom by dynamic teaching practises. It’s this all-round approach that ISL believes leads to the academic and personal success that characterises ISL pupils.
