EDUCATION ,EDUCATION research ,RESEARCH ,RESEARCH methodology ,EXPERIMENTAL design ,ANALYSIS of variance - Abstract
This article discusses the experimental design and analysis of research methods in educational research. Writings which have relevance to or are potentially useful for educational experimentation from either a long-range or a short-range point of view are, in general, noticed. In certain areas of experimental design, the analysis of variance, and related topics, only a representative number of the many papers which actually appeared have been considered.

STATISTICS ,STATISTICAL standards ,TEST design ,EDUCATIONAL evaluation ,RESEARCH methodology ,EDUCATIONAL tests & measurements ,EDUCATION research - Abstract
This article focuses on the statistical methods as research tools in education. A number of contributions to statistical methodology have been omitted in addition to those represented by the content of other chapters in this issue. In particular, those statistical methods that seemed to be especially applicable to problems of test construction, analysis, and evaluation were deferred for a chapter in a subsequent issue on educational and psychological testing. Thus, many contributions in the area of regression and correlation as well as recent writings on pattern and profile analysis have not been included. It would seem probable that within the next three years a sufficient accumulation of material on decision theory and discriminant analysis will be forthcoming to allow inclusion of a chapter on these topics for the 1960 issue of the "Review of Educational Research."

This article focuses on the status studies and sample surveys as research methods. The major impetus for status studies and the consequent attention to technics of sample surveys has been and still is the need for vital statistics which can be used for social research and the determination of public policy. The many technical articles published in recent years on the theory and methodology of sample surveys and the rise in the number of status studies demonstrate the need for a separate chapter on these subjects.

The article discusses various tests and measurements for research purposes in the fields of intelligence, special aptitudes and personality. Connection between achievement test scores and various other variables was included and an indication was made so that tests should pay added attention towards students urging them to express their thoughts in their own language. It became evident that girls averaged higher on marks, whereas boys averaged higher on achievement tests. Papers presenting useful techniques for achievement testing still fall short as these tests fail to measure all the desirable products of teaching.

TELEPHONE surveys ,INTERVIEWING ,SURVEYS ,RESEARCH methodology ,EXPERIMENTAL design - Abstract
A great deal has been written about the relative advantages of telephone and face-to-face interviews particularly with respect to comparative costs, sampling problems, interviewer reliability, refusal rates, and ease of administration. A special advantage of the telephone interview is the rapidity of the field work. Expense is likely to be considerably less, in terms of cost per completed interview, than in the face-to-face interview methods. It has also been argued that if facts, rather than opinions, are desired, the telephone approach has particular value. This article provides empirical data on the study of the comparative validity of the telephone and face-to-face techniques. This article presents a survey in which two comparable samples were interviewed with the same questionnaire, by the same interviewers, but by the two different approaches. The verbal claims and intentions of one group of respondents interviewed face-to-face in their homes will be compared with the verbal claims and intentions of another group interviewed by telephone. These statements will then be matched with the actual conduct of both groups, permitting an estimate of the comparative validity of the two interviewing methods.

The article focuses on the revealed difference technique to determine husband-wife interaction. It emphasizes whether the methodological innovation and the technique grew from successive sequences of pilot findings which led to research operations. The experiment was conducted on a group of couples from geographically adjacent communities in the Arizona-New Mexico area. It is concluded that the technique consists of requesting subjects to make individual evaluations of experiences shared by them. It also involves in requesting the subjects to reconcile differences in interpretations which may have occurred.

The article discusses anthropological approaches to the study of education. He suggested that the most promising approach would be the study of individually oriented networks coupled with lengthy fieldwork, microethnographic methodology, interviews and time sampling. In his conclusion, he explained that whatever methods are used in the future, it is important to correct certain biases which seem to characterize the field at present. In closing the author calls for more empirical discussion of methods and methodology in educational anthropolopy.

This article discusses the application of regression and correlation in educational research. Papers on regression cover a wide range of topics reflecting the diversification of problems in different areas of theoretical and applied statistics. A complication in regression analysis arises when it is unjustifiable to assume that the independent variables are free from errors of measurement. While the theoretical aspects of least squares analysis have been investigated since the beginnings of statistical science, certain techniques have emerged as particularly useful in the solution of these problems.

This article comments on studies concerning collective bargaining and the salaries of public school teachers. The study by Hirschel Kasper, which concluded that unionization has no impact on teacher salaries, is criticized for its research methods. The study by Robert Thornton, which reached the opposite conclusion, is noted for its appropriate specification of principal variables, but criticized for its lack of generality. The hypothesis that Kasper presents is that the average salary level relates positively to the level of organization.

The article is a reply to economist John Pencavel's comments about the article "Interindustry Variations in Voluntary Labor Mobility," which was in the January 1969 issue of "Industrial and Labor Relations Review." Standard multiple regression techniques were used in the study to determine the quit rate across manufacturing industries. Pencavel suggested modifications to the specification of equations, provided alternative estimates, and objected to the use of weighted regressions. He also offered evidence on the impact of wage supplements on voluntary separations. The authors disagree with Pencavel's assessment.

The article discusses the salary structure, as well as patterns and determinants of income, for engineering graduates. The data traces their earnings growth since graduation from a Canadian university with a bachelor's degree in electrical engineering. Regression analysis shows the impact of independent variables on income. Related factors such as the relationship between mobility and salary improvement are considered. A comparison is made of incomes for Canadian engineers, other Canadians, and U.S. engineers. Statistics from the 1960s indicate that starting salaries for graduates and mean earnings for experienced engineers were nearly identical to the corresponding measures for other engineering specialties. Fringe benefits are also mentioned.

The commentary focuses on the article "lnterindustry Variations in Voluntary Labor Mobility," published in the January 1969 issue of "Industrial and Labor Relations Review." Professors J. Burton and Y. Parker used standard multiple regression techniques to account for differences in the quit rate across manufacturing industries. There is a suggestion that research methods can be improved by modifying the specification of the estimating equation, offering alternative estimates, and outlining procedures for testing the effects of wage supplements on voluntary separations from employment.

Systematic study of gangs has been largely confined to this century. Five clear periods of development can be identified, two of them overlapping: 1900-1930--a pioneering period; 1980-1943--an era emphasizing social causality; 1940-1950--a decade of search for causal factors; 1942-1962--a period of disciplined observation which focused on the dynamics of ganging; 1950-1960--a decade of theorizing. The pioneer period appears to have been the most fertile era; subsequent theory and research largely confirm and extend the pioneer? work. The factor studies made heartening con tributions; though stemming from an empirical base with no unifying theory, they showed remarkable congruence in their findings; the observation studies showed less agreement. Studies with a single theoretical base show considerable discord in both theory and research findings. There is little consensus among gang theorists and researchers, and theorists pay little attention to available findings in elaborating new theory. There seems to be no "best" theory or research method. [ABSTRACT FROM AUTHOR]

The article discusses certain issues concerning laboratory experiments. Sociologists have been skeptical about the possibilities of laboratory experimentation as a method in sociological studies. The establishment of the validity of laboratory replicas of concepts has been more difficult in practice as compared to the validation of methods used in field studies. The skilled use of laboratory experiments is stated to result in presenting the findings with a higher degree of confidence than in the case of field studies. Laboratory experimentation requires a higher level of abstraction.

This article discusses various experimental designs used for social experiments. A pattern of practicable procedure has begun to emerge from the diverse experiments with the experimental method in education, psychology, and sociology. This pattern of procedure supplies the outlines of a long desired design for social experiments. One of the best documented and recorded results of an experiment that has been published is researcher, Stuart C. Dodd's, "A Controlled Experiment on Rural Hygiene in Syria." Dodd set out to discover the relationship between a program of rural hygiene and the hygienic practices of the families that were supposed to benefit by the program. Dodd decided to set up an experiment that would attempt to measure the effects of hygienic education upon the hygienic practices of a group of individuals and families. In Dodd's study, "Hygiene means all the knowledge, practices, and environmental conditions which are under the control of the family and which tend to increase health."

STATISTICAL power analysis ,STATISTICAL hypothesis testing ,EDUCATION research ,RESEARCH methodology - Abstract
This article presents a critique by the authors on appropriate uses and interpretations of statistical power analysis. The authors comment on the article "On the Power of Statistical Tests in the American Educational Research Journal," by J.K. Brewer in the 1972 issue of "American Educational Research Journal," vol. 9, and the book "Statistical Power Analysis for the Behavioral Sciences," by Jacob Cohen. Recent publications by Cohen and Brewer have focused attention on the desirability of including power considerations in the design phases of research. By designing studies with high levels of power, a researcher would probably avoid much of the frustration that generally accompanies failure to reject null hypotheses, there are several concerns that need clarification with respect to the specific procedures which have been suggested in the publications. The purpose of this comment is to clarify those concerns which seem most likely to cause confusion among practicing researchers. In pursuing these clarifications, the authors make reference to certain aspects of Brewer's article, in the hope of reducing the potential for misuse and misinterpretation of power analysis.

The article discusses education from sociological perspective. The author has presented both the conceptual basis for the subject matter of sociology and the salient character of the methodology used in its study of education. He stressed that the juxtaposition of these traditional areas of theory and method within sociology is more than an academic exercise because it provides a framework for a more systematic and comprehensive review of the methods of research used within the sociology of education. In his conclusion he provided an explanation to support his belief that there is no sociological perspective, but rather a range of theoretical approaches that are used to study social phenomena, that sociology, by comparison with some other sciences, lacks a single accepted conceptual framework.

The article discusses aesthetic inquiry and its role in educational research. The author has established that aesthetic inquiry is concerned with isolating a field of relevant data, interpreting it, and when most ambitious, with formulating hypotheses to explain the law-like reoccurrences that may appear in the phenomena under investigation. His very thesis in this article is to examine the methodological assumptions and the practical results of applying specific research techniques to "aesthetic" phenomena in order to determine the workability of educational procedures that depend upon various methods of aesthetic research. He presented some evaluations on several claims of psychologists, linguistic philosophers, and phenomenologist that they have the methods appropriate to develop a workable tool for teaching aesthetic materials.

The article focuses on the theoretical and experimental developments since 1962 that either employ computer-assisted instruction (CAI) as a research tool or focus on CAI as an educational system. CAI is the first high-speed electronic computer constructed to do millions of computations in a few instants. Some studies have utilized computers in the random generation of 2 to 5 values along five dimensions for the production of nonverbal sounds, which are: (1) frequency (2) amplitude (3) interrupt rate (4) duty cycle (5) duration. Another study has used computer to investigate quick memory processes and used to create random number-letter pairs, which have been suggestive for investigations of rehearsal hypotheses and the effect of rehearsal on the storage of information in memory.

This article deals with the two trends that are likely to be of considerable interest in the future in the field of educational research. These include the increasing amount of information available about educational systems outside the U.S. and the development of machines and systems of searching which permit quick access to ideas and combinations of ideas not easily located through conventional bibliographies, indexes, or abstracts. It discusses first the newer conventional bibliographical and reference aids which are primarily useful in the study of education in the U.S.; then the aids which are mainly useful in international studies; and, finally, the literature on systems for the mechanical indexing and searching of literature.

This article focuses on the scaling and measurement theory as the research tools. Traditional psychometric theory recognizes multiple criteria for evaluating a measurement procedure. Scaling theory should do likewise to avoid futile bickering as to whose numbers are on the side of the angles. This chapter covers scaling theory from June 1954 to June 1957. Limited space precluded several pertinent references, and those included reflect an attempt to give adequate coverage to developments deemed important by the reviewers.

This article highlights the library resources as the research tools. This chapter has been devoted to the technics and procedures for work with reference tools in the library. Research theory has always been ten to twenty years ahead of practice for many reasons. The development of action research, study councils, a variety of new reference tools, and summaries of research have been particularly valuable in stimulating application. This article also presents several references as guides of books as guides for research tools in education. Bibliography is also presented from these research tools.

this article presents the experimental design as a method of research. Many of the contributions to experimental design during the past three years should be incorporated rapidly into statistics textbooks designed for students in education and psychology. Authors of such books need the ability and willingness to translate into simpler but still accurate form relevant material published by mathematical statisticians. Then by studying for at least a year, and preferably longer, under a well-qualified instructor, graduate students may come to understand the rudiments of experimental design.

This article highlights the research tools of observing and recording group behavior. This review of the literature represents only a sample of the numerous research studies in the area. The authors have tried to limit their study to experimentation which more or less directly involves in its design the exploration and refinement of technics of observing and recording group behavior. It should also be noted that the total literature on this topic is not represented because of the exclusion of studies reported in languages other than English. The authors regret their lack of access to material from this expanding source.

The article presents information on recent developments in the field of statistical theory. A conceptual model was formed to deal with statistical data which is based on the theory of probability. The primary purpose of the theory of the design of experiments is to obtain maximum information from the data. The problem of estimation is the basis of statistical theory. The variance technique provides the appropriate method of evaluating the experimental error and carrying out the tests of significance with precision. According to modern research workers, inferences drawn from experimental results must be based on the knowledge of experimental principles at all stages of an experiment.

The article discusses important aspects of observational research methodology. Psychologists with keen observation, delegated to collect data either use written documents or recorded material. The use of life history method is based on insight interviews with the view of obtaining a clear understanding of race relations and problems of an all-African American community. The New York City Department of Health used the group method on rating schedule to evaluate candidates in terms of judging their appearance, manner of speech, attitude toward the group, leadership, contribution to group performance, and scientific approach. The questionnaire is the most frequently used observational technique, having advantages over administrative economy of time, money, and effort over other methods.

This article provides information about Rorschach methods and other projective techniques. It is indicated that the progress which has been made in systematizing research procedures, amassing scoring criteria and norms, using more scientific methods of handling data, adopting more adequate controls, employing statistical methods where they are applicable, and in applying scientific procedure to clinical validation. Today, the Rorschach represents one of the better methods for understanding the nature of personality, and is one of the more valuable instruments for use in clinical psychology.

The article discusses the weaknesses, pitfalls and mistakes of education research in the U.S. The sophistication of educators in research strategy and technique have been questioned and the suggested remedy for the accusation is the accelerated preparation in research methods as part of the graduate training. Education students are required to take a course in educational research. The content of the graduate training focuses on the discussion of research design, statistical techniques, computer utilization and proposal writing. Psychometrists and statisticians who teach from standard psychological texts of experimental design and analysis are the people responsible to teach the program.
