Methodology related to Lawrence Kohlberg's theory of moral development has been continuously refined by creation and evaluation of additional research instruments. Instruments have been tested at summer scoring workshops presented by Kohlberg and his staff at the Center for Moral Education, Harvard University, in 1972, 1973, and 1976. Instruments include: (1) a standard-form scoring system to redefine the stages of moral development at a structural level and distinguish more clearly between issues and concerns; (2) a structural interviewing system which penetrates beyond a subject's opinions, attitudes, and beliefs to basic reasoning or justification patterns; and (3) a standard moral-interview format, which directs the subject to make the choice at the beginning of each dilemma. Many problems related to interviewer misperception of values placed by the subject on a particular issue have been alleviated by asking the subject to weight the values. Other problems encountered by participants at scoring workshops relate to dominant-issue scoring. Participants should have fewer problems with scoring if they refer to Kohlberg's 1977 manual, average across elements within the governing norm, and consider unsolicited reasoning responses by the subject during the interview. The conclusion is that Kohlberg's moral development theory is constantly being improved as Kohlberg and other scholars work to make it more relevant to moral dilemmas. (Author/DB)
