Classroom Assessment Techniques (CATs)

A Guide for Faculty and Teaching Assistants

The following guide is designed to explain and give examples of how in-class assessment can enhance university teaching and learning. These techniques are based on the work of Angelo and Cross (1993). If you have questions about this material or would like to meet with the University Teaching and Learning Center, please e-mail utlc@gwu.edu.

What Are CATs?

Classroom Assessment Techniques (CATs) are, typically, ungraded activities conducted in the classroom setting. Their purpose is to provide the instructor feedback on whether or not students understand course material so that adjustments can be made before the end of the term. Frequent use of CATs also can assure students that the instructor takes a genuine, active interest in their learning process throughout the course, before the summative assessment (e.g., final exam) is given at the end of the term.

Why Should I Use CATs?

Frequent use of CATs:

  • Provides regular feedback about student progress and can preempt misconceptions and poor performance on more heavily-weighted tests, quizzes, projects, etc.
  • Gives insight into day-to-day teaching methods and student learning processes. It also can model to students the fact that learning is an ongoing and evolving process that can be modified as needed.
  • Provides students with a means of gauging their own learning styles and then modify study strategies as appropriate.
  • Helps students feel less anonymous in large class settings, since it is concrete evidence that the instructor cares about student learning.
  • Provides "food for thought" for instructors as they reflect on their teaching and on a particular course at the end of term.

Implementation and Examples of CATs

There are 50 tested assessment techniques from Angelo and Cross. The table below describes 8 techniques that can be easily adapted for and implemented in a classroom setting. For information on remaining techniques, please consult the Angelo and Cross book, which is available from the TLC Library (Angelo, T.A. and Cross, K.P. (1993). Classroom Assessment Technologies (Second Edition). San Francisco: Jossey-Bass Publishers).

Tips on implementation

  • Start off simple by choosing a technique that easily fits your teaching style and classroom time limits.
  • Conduct at least one CAT before the first major assignment, so that you can intercept any problems or questions before the fact.
  • Don't feel obligated to do a CAT every day or every week. You'll create information overload for yourself and "survey overload" for your students.
  • When you do any CAT, explain its purpose and your goal clearly to students.
  • Report your findings to your students and let them know what you plan to do in terms of their feedback.
Name Description What to do with the data Time required
Minute paper During the last few minutes of the class period, ask students to answer on a half-sheet of paper: "What is the most important point you learned today?"; and, "What point remains least clear to you?". The purpose is to elicit data about students' comprehension of a particular class session. Review responses and note any useful comments. During the next class periods emphasize the issues illuminated by your students' comments. Prep: Low

Chain Notes Students pass around an envelope on which the teacher has written one question about the class. When the envelope reaches a student he/she spends a moment to respond to the question and then places the response in the envelope. Go through the student responses and determine the best criteria for categorizing the data with the goal of detecting response patterns. Discussing the patterns of responses with students can lead to better teaching and learning. Prep: Low

Memory matrix Students fill in cells of a two-dimensional diagram for which instructor has provided labels. For example, in a music course, labels might consist of periods (Baroque, Classical) by countries (Germany, France, Britain); students enter composers in cells to demonstrate their ability to remember and classify key concepts. Tally the numbers of correct and incorrect responses in each cell. Analyze differences both between and among the cells. Look for patterns among the incorrect responses and decide what might be the cause(s). Prep: Med

Directed paraphrasing Ask students to write a layman’s "translation" of something they have just learned -- geared to a specified individual or audience -- to assess their ability to comprehend and transfer concepts. Categorize student responses according to characteristics you feel are important. Analyze the responses both within and across categories, noting ways you could address student needs. Prep: Low

One-sentence summary Students summarize knowledge of a topic by constructing a single sentence that answers the questions "Who does what to whom, when, where, how, and why?" The purpose is to require students to select only the defining features of an idea. Evaluate the quality of each summary quickly and holistically. Note whether students have identified the essential concepts of the class topic and their interrelationships. Share your observations with your students. Prep: Low

Exam Evaluations Select a type of test that you are likely to give more than once or that has a significant impact on student performance. Create a few questions that evaluate the quality of the test. Add these questions to the exam or administer a separate, follow-up evaluation. Try to distinguish student comments that address the fairness of your grading from those that address the fairness of the test as an assessment instrument. Respond to the general ideas represented by student comments. Prep: Low

Application cards After teaching about an important theory, principle, or procedure, ask students to write down at least one real-world application for what they have just learned to determine how well they can transfer their learning. Quickly read once through the applications and categorize them according to their quality. Pick out a broad range of examples and present them to the class. Prep: Low

Student- generated test questions Allow students to write test questions and model answers for specified topics, in a format consistent with course exams. This will give students the opportunity to evaluate the course topics, reflect on what they understand, and what are good test items. Make a rough tally of the questions your students propose and the topics that they cover. Evaluate the questions and use the goods ones as prompts for discussion. You may also want to revise the questions and use them on the upcoming exam. Prep: Med
