If you have been searching for free, high-quality, interactive educational resources for Singapore students — whether you are a student, a parent, or a teacher — you may have come across EdTechSims. This article explains what EdTechSims is, who it is for, what subjects it covers, and why it is different from other educational platforms.
What Is EdTechSims?
EdTechSims — short for Educational Technology Simulations — is a free online platform hosting a growing library of interactive learning simulations, virtual labs, and game-based educational activities. The platform covers a wide range of subjects taught in Singapore schools, from Chemistry and Physics to English grammar, Chinese language, Mathematics, Geography, and History.
Every activity on EdTechSims is:
- Free to access — no subscription, no account, no paywall
- Browser-based — works on any device (desktop, tablet, mobile) without installation
- Curriculum-aligned — built to match the MOE O Level and A Level syllabuses
- Interactive — students actively engage with content, not just read or watch
Who Is EdTechSims For?
Secondary school students — EdTechSims is most directly targeted at Sec 1 to Sec 4 students studying for O Level examinations. The simulations cover the key topics that appear in O Level papers and provide a way to explore concepts independently during revision.
Junior college students — A Level students will find tools for H2 Chemistry (Le Chatelier’s Principle, titration graphs, catalysis) very relevant and insightful.
Primary school students — Selected tools are appropriate for upper primary students, including basic fraction and decimal activities in mathematics and primary-level science concept explorers.
Teachers — EdTechSims activities are designed with classroom use in mind. Many teachers use the simulations as lesson demonstrations, student activities during computer lab sessions, or flipped learning assignments.
What Makes EdTechSims Different?
Many international simulation platforms — however excellent in their own context — are built for the UK GCSE, US AP, or Australian HSC curriculum. EdTechSims is built by a Singapore teacher with direct knowledge of the MOE syllabus, which means the terminology, topic coverage, and exam relevance are consistently on point.
Unlike many EdTech platforms that offer a limited free tier to drive paid subscriptions, EdTechSims is fully free to access. This reflects the belief that high-quality educational tools should be accessible to all students, regardless of their family’s financial situation.
The simulations at EdTechSims are designed to build genuine conceptual understanding — not just to help students memorise answers. The predict-then-reveal structure used in many activities is grounded in research on how people learn most effectively.
How to Navigate the Site
The homepage organises content by subject. Click on Chemistry, Biology, Physics, Mathematics, English, Chinese, Geography, or History to browse the available activities in each area. Within each subject, activities are labelled by level (O Level, A Level, or general) to help you find the most relevant tools quickly.
There is no sign-up required. Simply click on an activity and it opens directly in your browser.
A Growing Library
EdTechSims is actively growing. New simulations and activities are added regularly across all subject areas. If you are a teacher with a specific topic or activity in mind, the contact page offers a way to suggest future additions.
