Outcomes
To think about what makes effective written feedback in science using ideas from Black and Wiliam (1998)
| resources for science teachers who like to think

2. Key ideas of Black and Wiliam
Feedback focuses on the particular qualities of his or her work, with advice on what he or she can do to improve, and should avoid comparisons with other pupils.
Pupils should be trained in self-assessment so that they can understand the main purposes of their learning and thereby grasp what they need to do to achieve.
The dialogue between pupils and a teacher should be thoughtful, reflective, focused to evoke and explore understanding, and conducted so that all pupils have an opportunity to think and to express their ideas.
Tests and homework must be clear and relevant to learning aims. The feedback should give each pupil guidance on how to improve, and each students must be given opportunity and help to work at the improvement.

3. Effective feedback in science
You said H2O only changes to a gas at 100 oC. So why do clothes dry outside on the line at 22 oC?
Draw particles the same size for pure substances. Please draw (i) NaCl(s) and (ii) NaCl (aq).
Effective feedback in science
An element’s 2nd letter is always small e.g. Na NOT NA
Difficult to respond to but good feedback
Easy to respond to and good feedback
Quality of feedback
Underline titles.
Research about sublimation.
Difficult to respond to and little feedback
Easy to respond to but little feedback
Write the date and title. .
Don’t leave gaps.
You identify strengths of the model, but what are the limitations?
Ease for pupils to respond
Improve the quality.
