PLUS, MINUS, DELTA
​

​     Plus, Minus, Delta is a method of data collection that focuses on the learning process.  Following a lesson or activity, individuals respond to questions to clarify and reflect on what happened that day.
     In the Plus column, the actions or steps that contributed to learning are recorded in a positive way.  The Minus column indicated the actions that interfered with learning.  The Delta column requires the group to reflect and problem solve.  Reasonable changes that will increase opportunities for learning in the future are conveyed and recorded.  The information is posted in the room and reviewed before the next lesson to remind children about what they did well, what impeded learning, and what opportunities for improvement could be implemented to enhance learning in the future. These have been used frequently in classrooms and at faculty meetings in our school.
     When this data source was introduced at grade level meetings, the teachers created a list of possible ways Plus, Minus, Delta charts could be used within the building. They are listed below:
*behavior issues/recess and lunch situations
     *following directions
     *ability to focus
     *transitions and unstructured times
     *clean up and completing class jobs
     *when guest teachers are in the building
     *understanding of academic skills (eg. science, math problem
       solving, evidence based reading responses, opinion writing)
     * “pre” and “post” testing
     *staff meetings
