Classroom exercise suggestions


1) One of the primary goals of this chapter is to provide students with an overview of the many different research approaches and data collection methods available to researchers. Remind students that much of the information contained in the chapter will be explored more fully in other sections of the text. To bring home the point that many topics can be explored in multiple ways you might use one of the activities below:


  • Ask the class to generate ideas of student behaviors that they would be interested in studying (e.g., chatting on Facebook, partying, couples holding hands etc). Lead the discussion toward a single behavior that could be researched. After a behavior is selected this should lead to a discussion of operational definitions as you define precisely the behavior that will be studied. This is a good opportunity to point out that many psychological constructs can be operationalized in multiple ways. After the target behavior has been properly defined have students think of the different research approaches presented in the chapter and how they might use these to study the behavior. Depending on the behavior chosen students should have no trouble identifying several different methods that could be used. Finally, you should also prompt them to relate each method to an objective of science (description, prediction, etc) presented in chapter 1.


  • As an alternative to the activity above you might provide groups of students with a simple hypothesis and ask them to brainstorm ideas of how it could be tested. Providing each group with the same hypothesis will give you (and the other students) an opportunity to discuss the advantages and disadvantages of each suggested multiple research appraoches.


  • I use one or both of the activities above and then continue to reference them throughout the semester. As we discuss more advanced designs our original research idea becomes more and more complex.


2) At this point in the semester it will be difficult for most students to decipher scientific journal articles but one easy way to help them distinguish different research methods is by utilizing popular media reports of scientific research. This also encourages students to exercise their critical thinking skills an important goal of the course. There are several ways you might incorporate this in your discussion:


  • Have students bring to class popular media reports of scientific research (e.g., from magazines, newspapers, or from online sites like Google news). Ask students to indicate the type of research approach used (e.g., experimental or correlational), the most important results of the study, and any explicit or implied implications of the findings. In many cases students will find it difficult to determine the type of research design that was used in the original study (e.g., correlational or experimental). They may also find unwarranted implications of causality for instance when the original research design was simply correlational.


  • Jonathan Mueller maintains a very good website containing links to media reports (and often misrepresentations) of scientific research. In many instances research findings from correlational studies are reported in a way that implies causality. In addition to the article links this site also includes multiple student activities that would be appropriate to accompany your discussion of this chapter.



  • Finally, Hall and Seery (2006) present an activity in which students compare media reporting of a research finding to the original source. They report that the activity is effective in making students more aware of the limitations of media reporting of research findings.


Hall, S.S. & Seery, B.L. (2006). Behind the facts: Helping students evaluate

media reports of psychological research. Teaching of Psychology, 33, 101-104.


3) The text points out that correlational research is helpful in accomplishing the scientific objectives of description and prediction. To extend this discussion you might describe how correlational research often stimulates hypotheses that are tested in an experimental manner thus establishing causality and accomplishing the objective of explanation. For example, correlational research finding a positive association between playing violent video games and aggressive behavior is difficult to interpret because of issues of direction of effect and potential third variables. However, these findings have stimulated a wealth of experimental research investigating the precise nature of the causal relationship. For the correlational findings below have students generate ways to test the relationship experimentally. The discussion should naturally lead to issues of random assignment and control of extraneous variables. This may also serve as a preview of ethical issues involved in using random assignment.

  • Students who sit at the front of the classroom make better grades than those that sit in the back.
  • Researchers have found a positive relationship between the degree of satisfaction couples feel experience in their relationship and the amount of time they spend together.
  • There is a negative relationship between exercise and anxiety.
  • Participation in leisure activities has been associated with a lower risk of dementia in older adults.


4) The site below, maintained by Alan Levine, presents simple explanations for five different research methodologies (experimental, correlational, naturalistic observation, surveys, and case studies). The site is well-done and contains summaries and quizzes for each of the five methodologies.



5) This University of Denver site provides links to various online experiments in which students can participate. You may find this to be more appropriate for later in the course.
