PLUS/DELTA Classroom Assessment Technique

PLUS/DELTA Classroom Assessment Technique

As instructors we often want to know how things are going in our course from the students’ perspective. The Plus/Delta feedback tool (sometimes called Plus/Change) is a means of identifying what is going well and what needs to be changed. The beauty of this tool is that it asks students to focus on what is working to advance their learning in the course and what could be improved by the teacher and the student. It helps students to think about their responsibility to the course and what they should continue doing to learn (PLUS) and what they need to change for the course to improve for them (DELTA) (Helminski & Koberna, 1995).

Here’s how it works. Students divide a sheet of paper into quadrants. On the top left quadrant the student identifies what is working to enhance learning in the course. In the lower left quadrant the student writes what the student is doing to enhance his/her learning in the course. In the upper right quadrant the student identifies what needs to change or improve in the course or teaching approach to enhance learning. In the lower right quadrant the student identifies what he/she needs to change or improve in order to enhance his or her own learning.

These responses may be collected, summarized, and reported back to the students at the next class session, or a four-quadrant chart can be drawn on the board and students can verbally offer responses. Or you may want to combine these two response methods. In either case, it is important to close the feedback loop and share the data with students.

What is helping me to learn in this class? What changes are needed in this course to improve learning?
What am I doing to improve my learning in the course? What do I need to do to improve my learning in this course?
