2020–22

Subject Head of Biology · Merchiston International School

Two years leading biology at a British boarding school, with top A Level results, and completing my Master of Education with a year-long study of STEM clubs.

These years brought together leadership, results and research. With my department I aligned every assessment to Cambridge standards. In my own classes I tested an idea I had long believed in: hands-on STEM experiences change how students see science.

The STEM Club study. I randomly assigned Grade 8 students to an experimental group (STEM Club plus regular lessons) or a control group (regular lessons only). After a year, the experimental group’s grades had risen by about 20% on average while the control group’s dipped slightly. Interviews showed students linking club activities to a clearer picture of STEM careers.

Reflection. The hardest part was not the experiment but bringing parents on board with an activity that had no immediate effect on grades. I learned to communicate the purpose of enrichment as carefully as I plan it.

Goals for the year

  • Lift examination outcomes at IGCSE and A Level
  • Align assessment fully with Cambridge (CAIE) standards
  • Find out whether a STEM club changes students’ achievement and motivation

What I did

  • Designed CAIE-aligned assessments and digital learning resources for Biology and Chemistry
  • Wrote IGCSE Chemistry lesson notes on organic chemistry and energetics, and the laboratory safety rules for pupils
  • Mentored three new teachers through curriculum implementation
  • Ran a year-long STEM Club study with Grade 8 students as my MEd capstone

Impact

  • 100% A*–B in A Level Biology
  • 70% pass rate in IGCSE Biology and Chemistry
  • STEM Club students’ assessment grades rose by about 20% on average over the year, compared with a slight dip in the control group

Professional learning

  • Master of Education in Advanced Teaching completed (University of the People, 2021)
