Language for Effectively Communicating Assignments

Language is a critical element in properly communicating the intent of assignments to students. When your assignments are clear, your students are more likely to produce what you want. This teaching tip explains what is really meant by some common task descriptors. When you review the assignment with your students, consider explaining the terms you have used to be sure they understand what you mean. 

Common assignment tasks and task descriptors 

In addition to the suggestions in this table, review CTE Teaching Tip: Bloom’s Taxonomy Learning Activities and Assessments for additional ways to categorize assignment tasks and corresponding verbs or task descriptors.  

When you want students to… 

…ask them to… 

Identify cite, define, enumerate, give, identify, indicate, list, mention, name, state. 
Describe describe, discuss, review, summarize, draw, illustrate, sketch, develop, outline, trace. 
Relate analyze, compare, contrast, differentiate, distinguish, relate. 
Demonstrate demonstrate, explain why, justify, prove, show, support. 
Evaluate assess, comment, criticize, evaluate, interpret, propose. 

Sample task descriptors and what they really mean 

  • Analyze:  Divide a complex whole into its parts or elements, laying bare parts or pieces for individual scrutiny, so as to discover the true nature or inner relationships. 

  • Compare: Look for qualities or characteristics that resemble each other. Emphasize similarities among them, but in some cases also mention differences. 

  • Contrast: Stress the dissimilarities, differences, or unlikeness of things, qualities, events, or problems. 

  • Criticize: Express your judgment about the merit or truth of the factors or views mentioned. Give the results of your analysis of these factors, discussing their limitations and good points. 

  • Define: Give concise, clear, and authoritative meanings. Don't give details, but make sure to give the limits of the definition. Show how the thing you are defining differs from things in other classes. 

  • Describe: Recount, characterize, sketch, or relate in sequence or story form. 

  • Draw: Give a drawing, chart, plan, or graphic answer. Usually, you should label a diagram. In some cases, add a brief explanatory description. 

  • Discuss: Examine, analyze carefully, and give reasons pro and con. Be complete and give details. 

  • Enumerate or list: Write in list or outline form, giving points concisely one by one. 

  • Evaluate: Carefully appraise the problem, citing both advantages and limitations. Emphasize the appraisal of authorities and, to a lesser degree, your personal evaluation. 

  • Explain: Clarify, interpret, and spell out the material you present. Give reasons for differences of opinion or of results and try to analyze causes. 

  • Illustrate: Use a figure, picture, diagram, or concrete example to explain or clarify a problem. 

  • Interpret: Translate, give examples of, solve, or comment on a subject, usually giving your judgment about it. 

  • Justify: Prove or give reasons for decisions or conclusions, taking pains to be convincing. 

  • Outline: Organize a description under main points and subordinate points, omitting minor details and stressing the arrangement or classification of things. 

  • Prove: Establish that something is true by citing factual evidence or giving clear logical reasons. 

  • Relate: Show how things are related to, or connected with, each other or how one causes another, correlates with another, or is like another. 

  • Review: Examine a subject critically, analyzing and commenting on the important statements to be made about it. 

  • State: Present the main points in brief, clear sequence, usually omitting details, illustrations, or examples. 

  • Summarize: Give the main points or facts in condensed form, like the summary of a chapter, omitting details and illustrations. 

  • Trace: In narrative form, describe the progress, development, or historical events from some point of origin. 

Common information sources and considerations for students 

For additional examples of information sources, the Library has useful “Source types” and “Evaluating Information Sources" research guides.  

  • Web-based: There are many types of online information, including e-journals, websites for various organizations (educational, government, non-profit, etc.), news websites, blogs, and more. When you discuss “web-based” resources, be specific about what sort of online information you are referring to and encourage students to evaluate their sources. 

  • Scholarly journals:  Articles are long, use terminology or jargon of the discipline, usually begin with an abstract and include a bibliography (e.g., Canadian Journal of Experimental Psychology; Journal of Academic Librarianship; IEEE Transactions on Microwave Theory and Techniques). 

  • Popular journals:  These are geared towards a more general audience and available on your local newsstand. Articles are short and rarely have bibliographies. (e.g., Maclean’s, Discovery, Psychology Today, Time, Newsweek). 

  • Peer reviewed (or refereed) journal articles: Explain the process of having experts in the field examine an article before it is published to ensure that the research described is sound and of high quality. Refer students to the Notes for Authors section of a journal to determine if it follows peer review. Alternately, refer students to  the Library’s Peer-reviewed journal articles webpage or UlrichsWeb Global Serials Directory 

  • Primary sources: These provide firsthand information in the original words of the creator or eyewitness and may include creative works, original documents, reports of original research, or ideas. 

  • Secondary sources: These provide information reviews and/or, evaluation, analysis, or interpretations of primary sources. 

  • Current:  Specifically define your boundaries for “current.”  Do you mean “current” as in this week, this year, this decade, this century, etc.? Can students refer to older material at all, if it is relevant?
