The Difference Between Formative and Summative Assessment
Summative assessment measures what students have learned at the end of a unit, term, or year. Formative assessment is ongoing, embedded in daily instruction, and designed to inform teaching decisions in real time.
Research by John Hattie, whose meta-analysis of over 800 educational interventions is the most comprehensive in the field, consistently ranks formative feedback among the highest-impact practices available to teachers, with an effect size of 0.70 — more than twice the average effect of any educational intervention.
8 Formative Assessment Strategies That Work
1. Exit Tickets — A brief written response of two or three questions that students complete in the last five minutes of class, directly assessing the lesson's learning objective. Sort exit tickets into three piles: "Got it," "Almost there," and "Needs re-teaching." Use this data to plan the next day's warm-up or small group instruction.
2. Think-Pair-Share — Pose a question, give students 60 seconds to think independently, then have them discuss with a partner before sharing with the class. The independent thinking phase ensures all students process the question before hearing their partner's answer.
3. Mini Whiteboards — Students write their answers on small whiteboards and hold them up simultaneously when you give the signal. Simultaneous reveal prevents copying and gives you instant whole-class data.
4. Hinge Questions — A carefully designed multiple-choice question placed at a critical point in the lesson. Each answer option is designed to reveal a specific misconception, giving you precise diagnostic information.
5. Socratic Questioning — Rather than accepting the first correct answer, use follow-up questions to probe student thinking: "How do you know?" "Can you explain that in a different way?" "What would happen if we changed this variable?"
6. Traffic Light Cards — Give each student three cards: green (I understand), yellow (I am not sure), red (I am confused). Students display the card that represents their current understanding, giving them a non-threatening way to signal confusion.
7. Two Stars and a Wish — When reviewing student work, provide feedback in the format of two specific strengths and one specific area for improvement. This structure ensures that feedback is balanced, specific, and actionable.
8. The 3-2-1 Reflection — At the end of a lesson, ask students to write: 3 things they learned, 2 things they found interesting, and 1 question they still have. The "1 question" component surfaces lingering confusion and gives you a direct window into what needs to be revisited.
