Case Method


The case method (or the case study) is a prolonged, intimate, and detailed investigation of a single case or a set of cases. The in-depth analysis of a case or small set of cases illuminates larger sociological processes and phenomena. The case method is used in urban and rural ethnographies, life histories, and social histories of a group of people or an event. Cases can be empirical, theoretical, or discovered during the research process. The case method requires an ongoing, engaged, and critical conversation between data collection and data analysis. Typically, the social scientist using the case method refines her definition of a case throughout the course of a study (Becker 1992). The case method is especially useful in illuminating social worlds that are not appreciated or understood by others.

The history of the ethnographic case study is grounded in a volume of works produced by the Chicago school during the early twentieth century. Early Chicago school scholars used the case method to illuminate peoples understanding of urban culture (Zorbaugh [1929] 1976), race and ethnic relations, and social problems such as homelessness (Anderson and Council of Social Agencies of Chicago 1923), poverty and segregation (Wirth 1928), deviance, and delinquency (Thrasher 1927). The naturalistic case study grounds observations and concepts in everyday social interactions and processes, which are observed directly by the researcher. Social scientists using the extended case method seek to complicate or extend extant concepts and theory by explicitly linking the case under study to local, national, and global trends and histories (Burawoy 1998).

Today, the case method is valued for its utility in labeling previously undocumented or misunderstood activities and understanding complicated social or historical phenomena, including social problems such as poverty, homelessness, drug use, and inner-city violence. Like early Chicago school scholars, contemporary social scientists use participant observation and in-depth interviews to systematically examine a social group or social phenomenon, while also developing new and innovative ways to collect data (Emerson 2004). In addition to data collected from direct and participant observation, the case method also takes advantage of the available quantitative data, including public records, and, at times, archival data. The primary data source for ethnographic case studies is the field researchers notebook. Throughout the research process, the social scientist takes copious field notes, which are essential to data analysis and to the final presentation of the study to outside audiences (Emerson 2004). A common analytical tool used in case studies is analytical induction; a working hypothesis is developed once the researcher begins to collect data on his first case and then tests and refines his developing theory throughout the process of data collection and analysis (Becker 1998). Typically, the findings from a case study are presented in narrative form, as a story that conveys the lived experience of the social group, actor, organization, or historical event.

Large quantitative studies (such as a population census or a large-scale survey) emphasize researcher objectivity. In contrast, the case method uses a researchers subjectivity (Ragin 1997) or reflexivity (Burawoy 1998) as a tool to deepen ones understanding of a social group or phenomenon. Field researchers who are concerned with limiting the influence of researcher bias may construct a team of field researchers that will effectively standardize the process of data collection and analysis (for example, Newman 1999). A noted strength of the case method approach is the validity of its findings. Typically, the researcher using the case method has a wealth of sources including field notes, interviews, media reports, and archived materials to triangulate or cross-check during the research process. Critics also argue that the case study method does not allow for the generalization of findings to a much larger population of cases. Some researchers identify this as a limitation of the case method in the presentation of their findings, while others argue that one can generalize from a single case study to others, if similar conditions exist (Becker 1967).

Social scientists who use the case method help to complicate our understanding of everyday life, social processes, and social phenomena in ways that are elusive or impossible for quantitative-based studies to accomplish. At times, the most rigorous case studies will form the foundation of larger quantitative studies. The deep insight generated from the case study illuminates the many problems that concern contemporary social scientists.

Case Method

views updated


A system of instruction or study of law focused upon the analysis of court opinions rather than lectures and textbooks; the predominant method of teaching in U.S. law schools today.

christopher columbus langdell, a law professor, often receives credit for inventing the case method although historians have found evidence that others were teaching by this method before him. Regardless, Langdell by all accounts popularized the case method.

Langdell viewed the law as a science and believed that it should be studied as a science. Law, he said,

consists of certain principles or doctrines. To have such a mastery of these as to be able to apply them with constant facility and certainty to the ever-tangled skein of human affairs, is what constitutes a true lawyer; and hence to acquire that mastery should be the business of every earnest student of law.

Each doctrine, Langdell said, arrived at its present state by slow degrees, growing and extending through centuries. Langdell's beliefs differed from those of his law professor colleagues. Throughout the 1800s, the prevalent approach for teaching law school classes was the lecture method. Although professors and textbooks interpreted the meaning of various court decisions, they did not offer a significant opportunity for students to do so on their own. The case method, on the other hand, forced students to read, analyze, and interpret cases themselves. It was Langdell's opinion that law students would be better educated if they were asked to reach their own conclusions about the meaning of judicial decisions.

Langdell's ideas were, at first, overwhelmingly rejected by students, other law professors, and attorneys alike. These critics viewed the case method as chaotic compared with organized lectures. They believed that instead of soliciting law students' opinions regarding cases, professors should simply state their own interpretations. Law students, afraid that they were not learning from Langdell's method, dropped out of his class, leaving him with only a few pupils. Enrollment in the Harvard Law School decreased dramatically because of concern over Langdell's case method and alumni called for his dismissal.

But the president of Harvard University, Charles W. Eliot, supported Langdell and his case method. This backing allowed Langdell to withstand the criticism long enough to prove the case method's success: Langdell's students were becoming capable, skilled attorneys. In 1870 Langdell became law school dean. As time passed he replaced his critics on the Harvard faculty with professors who believed in his system of teaching and the case method soon became the dominant teaching method at Harvard. Other U.S. law schools took note. By the early 1900s, most had adopted the case method, and it remained the primary method of legal instruction throughout the twentieth century and beyond.

The case method is usually coupled with a type of classroom teaching called the Socratic method. Through the Socratic method students orally respond to an often difficult series of questions designed to help them gain further insight into the meaning of the law. Students learn the skill of critical analysis this way: they learn to discern relevant from irrelevant facts; they learn to distinguish between seemingly similar facts and issues; and they learn to analogize between dissimilar facts and issues.

The case method offers certain benefits. For one, cases are usually interesting. They involve real parties with real problems and therefore tend to stimulate students more than do textbooks with only hypothetical problems.

The case method also helps students develop the ability to read and analyze cases, which is a crucial skill for attorneys. Students learn to reduce cases to four basic components: the facts of the controversy; the legal issue that the court decides; the holding, or legal resolution, that the court reaches; and the reasoning that the court uses to explain its decision. Students, especially in their first year of legal study, often outline these components in written case briefs, to which they can refer during classes and while they prepare for exams.

Another advantage of the case method is that it teaches, by example, the system of legal precedence. By reading cases, students learn how and why judges adhere, or do not adhere, to law developed in previous cases. Students also learn how judges have the discretion to create law by construing statutes or constitutions.

The case method continues to have critics. One criticism focuses on law school examinations. Typically, law students are tested only once in each class. They face enormous pressure to perform well on this examination since their single score on it usually constitutes their entire grade for the class. It is difficult to test analysis skills, so often these examinations test the students' ability to spot legal issues and apply legal rules. Therefore, although professors try to teach case analysis skills, students tend to focus on simply learning rules of law in the hope of getting good grades. This diminishes the case method's intended result.

The case method may be unpopular with law students owing to the amount of reading it requires. It is not uncommon for law professors to assign twenty to thirty pages of reading, containing excerpts from four or five cases, each night for each class. Some law professors have argued that pupils learn to analyze cases within the first few months of law school, and that thereafter the case method becomes ineffective because students lose enthusiasm and interest in reading cases.

Another complaint concerns the role of casebooks. Casebooks commonly contain cases or case excerpts as well as some explanatory text. They are most often compiled by law professors, who arrange the cases to show legal development or illustrate the meaning of legal principles. These casebooks provide only a small sample of cases, the vast majority of them appellate-level decisions. Thus, law students usually receive little or no exposure to decisions of trial courts. Some commentators suggest that students therefore miss critical elements of a lawyer's initial role: discovering and shaping facts and determining legal strategies to present to the court at the trial level.

Frequently, students do not see legal conflicts in their undeveloped form until they graduate and begin practicing law. Law schools increasingly are trying to remedy that problem by offering instruction in basic lawyering skills. For example, classes in trial advocacy allow students to conduct mock jury trials. Other courses teach client-counseling skills, document-drafting skills, and oral argument skills. The idea is not to abandon the case method entirely but to balance it with other teaching methods.
