This learning strategy helps students examine ideas, concepts, and experiences from more than one perspective before drawing conclusions or making decisions.

Why use it?

  • To enhance critical thinking skills
  • To identify and consider different perspectives on a topic, idea or concept
  • To support innovation and creativity
  • To enhance effective communication skills

Tips for success

  • Provide students with the template prior to starting the discussion, reading the article or viewing the resources.
  • Choose topics, ideas or concepts that encourage different viewpoints; students can critically examine texts, analyze the implications or consequences of actions and/or stimulate the sharing of various thoughts and ideas.

How do I use it?

  • Consider a topic, idea or concept for discussion that you would like the students to think about from various perspectives.
  • Divide students into pairs or small groups to brainstorm responses to the prompts for the steps below:
    • STEP 1 - P: What are all of the positive points you can think of?
      • In this step, students list all of the positive things. Ensure students don’t critique themselves but brainstorm all the positive points on the topic that they can think of.
    • STEP 2 - M: What are the negative points you can think of?
      • In this step, students list all of the negative things. Remind students not to critique themselves but remain focused on the negative points on the topic they can think of.
    • STEP 3 - I: What are the interesting points to which you should pay attention to?
      • In this step, students list everything they find interesting on the topic. Ensure students focus on points of interest that they should direct their attention to.
    • STEP 4: Determine a conclusion after considering the points above.
      • In this step, students make their conclusion after reviewing the positive, negative and interesting aspects on the topic.

Variations 

  • You may want to engage in this process as a whole class discussion instead of pairs or small groups.
  • You can also have students use different colours or sticky notes instead of using the template.

Extensions

  • The PMI strategy is also valuable when examining solutions to scenarios or problem based learning. It can also help to establish what is already known or understood about a topic, idea or concept. Use this strategy when you find students are rushing to conclusions without talking through the problem or issue.
