The Assessment Triangle

Sometimes when we hear the word “assessment,” we think of students silently completing a multiple-choice exam during class. But, there are a variety of ways to assess learning, and how we assess it depends on which skills and ideas we are interested in finding out what students can do.

Assessment Triangle

The assessment triangle helps us think about how we should assess because it connects what we want students to know and do with how we plan to observe what they know and can do. There are three points on the assessment triangle: cognition, observation, and interpretation (National Research Council, 2001).

Three textboxes connected with two way arrows: cognition, observation, and interpretation. Includes descriptions next to each box.

Cognition

Which concepts and skills do students need to know and do?
There are likely some concepts that students need to memorize. There might, though, also be skills that we are interested in students being able to do. For instance, maybe students need to be able to create something, such as a research question for a study and applicable methods. Maybe they need to solve problems and interpret data. What are you looking to assess?

Observation

What types of tasks will illustrate student knowledge and skills?
What you have students do for the assessment will be determined by what you want them to know and do. There are a variety of ways to assess, such as (and these are just a few examples):

  • Multiple choice exam
  • Essay exam
  • Group exam
  • Project
  • Research investigation
  • Case study (real life or fictitious)
  • Poster
  • Research paper
  • Infographic
  • Presentation

Interpretation

How will the tasks determine student knowledge and skills?
Once students complete the assessment, how will understanding be identified? That is, how will the assessment be scored? Scoring or grading rubrics can be a helpful start in identifying your expectations of how a student might approach an assessment and how accurate each approach is (or how many points each one is). Rubrics can either have everything graded on a single scale or can be broken down into separate criteria, culminating into one grade for the task. There are many guides available online for creating rubrics, such as from UC Berkeley’s Center for Teaching and Learning.

Try it for Yourself

Draw a triangle on a piece of paper. Label each corner: cognition, observation, and interpretation. Choose a few cognitive aspects that you teach together in a single lesson or unit, identify how you might observe understanding of those cognitive aspects, and how you might interpret your observations.
