I created this rubric to asses my students' presentations. I have used it successfully for years. Page 1 can be used for individual presentations and Page 2 for up to 4 students giving a Group Presentation. This rubric is designed such that it can be used for any subject.
This rubric is divided into 3 categories: Speaking, Presentation (visuals) & Content. Each category lists several features of a (usually good) presentation, e.g., speaking loudly enough, not reading the slides verbatim, demonstrated critical thinking, etc.
*IMPORTANT* This "rubric" does not give values or points for different categories. Instead, next to each item (for each student) there are simple check boxes for "needs work" (C), "good" (B) and "superior" (A).
When I use this myself, I listen and tick as I go, making notes in the margins, e.g., "font size about 18" or "good references." Then, after class, I can generally see from my check marks if the student is in the A, B or C category and use my margin notes to narrow down the grade further (e.g., B+).
There is a place at the top of the page for the title of the presentation and student(s) name(s). This is an Excel file so you can add and remove items that may not apply to your course. Page 2 prints landscape to fit up to 4 students.
