Chemistry & Biology Educator
Cambridge AS & A Level · IGCSE · International Examiner
I'm Ishaku Yunana, a science educator with over six years of teaching from Year 7 to A Level. I teach Cambridge International AS & A Level Chemistry (9701), Cambridge IGCSE Chemistry and Biology, and prepare students for WAEC, JAMB, GCSE and OSSD exams.
As an international examiner for Cambridge University Press & Assessment and Pearson Edexcel, I know exactly what mark schemes reward, and I teach my students to write answers that earn the marks. I'm completing an M.Sc. (Ed.) in Chemistry Education at Obafemi Awolowo University, researching how AI tools and PhET simulations support chemistry learning.

Inclusive teaching
SEN & One-to-One Support
Patient, differentiated lessons for students with special educational needs or anyone who needs a slower, steadier pace.
My goal is not just to teach students about science, but to teach them to think like scientists: curious, critical and creative.
My teaching philosophy
Discovered, not memorised
Inquiry, experiments and PhET simulations let students explore ideas for themselves.
Every learner matters
I differentiate for each student, including those with special educational needs.
Learning through relationships
Respect and open communication make it safe to ask questions and make mistakes.
Teaching shapes lives
Through Madonna Teen Impacts I mentor teenagers to grow in confidence and leadership.
Lifelong learning
I keep developing through research, certifications and collaboration.
