Education A to Z

Education and Curriculum Terms: A Guide for Students and Teachers

Please note: This page explains a word or a process in education. It is general information about the system, the law and the guidance in England — not advice about your child, your school or your exam. If a decision is going against you, get advice from one of the free services we link to before you agree to anything or miss a deadline. If you are revising, check your own exam board's specification: boards word things differently and yours is the one that marks you.

Revising? We write GCSE revision songs — a playlist covering most subjects and the English set texts. Listen to the revision playlist.

40 terms filed under R, showing 1–10 (page 1 of 4).

R

Radioactivity

Unstable nuclei, three kinds of radiation, and half-life.

Rates of reaction

How fast a reaction goes, and the five things that change it.

Ratio and proportion

Comparing quantities, sharing amounts, and quantities that vary together.

Ratio problem solving

The wordy ratio questions that carry several marks.

Reactivity series

Metals ordered by how readily they react, and what that predicts.

Reading a graph in science

Drawing and interpreting graphs, including gradients and lines of best fit.

Reading a specification

The document that says exactly what you can be examined on. Free, and rarely read.

Reading for meaning

The short comprehension questions. Easy marks, and easy to overrun on.

Rearranging formulae

Changing the subject of a formula so a different letter is on its own.

Reasonable adjustments

Changes a school must make so a disabled child is not put at a substantial disadvantage. A duty, not a favour.
