If they are to develop more effective social intervention strategies, social scientists must pay attention to social causality in their research. This will lead to more credibility for the social sciences and more support for research funds. Social causality is defined as a social process that produces a change in some dependent variable. It…

A 2-to-the-kth-power mirror-image design is defined as one in which repeated observations of subjects occurs among the levels of a usual 2-to-the-kth-power design, but there is the restriction that no subject may receive a given level of any factor more than once. Such a restriction might arise, for example, if a subject's response is expected to…

An alternative research methodology is presented which focuses on the aims and values of education while attending to the learner as an elaborate, dynamic, everchanging total system. A summary covers the reactive, preactive, proactive, and spiralling learner systems, each of which meet the definitional system requirement of being dynamic, having a…

This paper presents five designs (three one-group and two two-group) which can be effectively employed to study computer-based methods in non-laboratory settings, including actual classroom implementation, where a non-treatment control design may not be feasible. These designs are sequential analysis, value-added analysis, non-equivalent dependent…

This paper (1) presents observations about the major paradigms and assumptions that have historically shaped media research; (2) encapsulates the activities, thinking, and paradigms of the present; and (3) reports on a study in which 100 theoreticians and researchers were asked to respond to 50 hypothetical statements about media in the learning…

As a step toward developing a standardized measure for evaluating the impact of child protective services, three indices were developed: the abuse index, the neglect index, and the sexual abuse index. Each is composed of physical indicators of the problem and social and behavioral indicators found to be statistically correlated with physical…

This article describes the development and use of single subject research and evaluation for individuals involved with counseling. The case study approach and intensive design are examined in detail. (EJT)

A course in applied statistics for social science students provides for students designing experiments at an interactive terminal. (SD)

An argument has been developed suggesting that a research model appropriate to open education evaluation could be systematically developed out of the writings of Jean Piaget, Jerome Bruner, Robert White, and M. Brewster Smith. (Author)

A substantial body of data and a number of reviews of the literature on risk encouraged this attempt to construct a theoretically consistent approach to research on risk. Much of the research can be seen as attempting to estimate the probability that development will be compromised for groups of infants born under different circumstances. Linear…

Replication is important to viable scientific inquiry; results that will not replicate or generalize are of very limited value. Statistical significance enables the researcher to reject or not reject the null hypothesis according to the sample results obtained, but statistical significance does not indicate the probability that results will be…

The value of variance is emphasized, and the element of design, frequently not adequately understood, is clarified to underscore the importance of variance to the researcher. Two analytic methods, analysis of variance (ANOVA) and multiple regression, are discussed in terms of how each uses/applies variance. Advantages and major difficulties with…

The postsecondary seminars report presents the distillation of the discussions and the recommendations of approximately 115 representatives of educational institutions, associations, and State and Federal agencies attending the Postsecondary Education Seminars Conference of 1976. The conference addressed the changing nature of postsecondary…

This paper reviews empirical studies of the efficacy of the use of computer assisted instruction (CAI) in various settings, with particular attention to the use of CAI to teach mathematics skills and concepts. Studies using students at various ages and various subjects are considered, as are applications in which CAI was used as the primary…
