All students should leave school with the skills, confidence and experience to stand up in front of an audience and deliver an individual or group presentation. Presentations may vary in length and nature but should always have clear aims and instructions. Are the students allowed/expected to use powerpoint slides or other visual aids? Are they allowed/expected to include practical demonstrations? Is the presentation a quick feedback after a group work session or the culmination of a long project? Will they be marked on content alone or will their presenting style carry any weight? Assessing work through oral presentations as well as written tasks allows different students to shine and the immediate questioning which can follow allows the teacher to ascertain understanding, challenge misconceptions and stretch the more able.
