Abstract

Some authors on research methodology are of opinion that research reports are based on the logic of reasoning and that such reports communicate with the reader by presenting logical, coherent arguments (Böhme, 1975:206; Mouton, 1996:69). This view implies that researchers draw specific conclusions and that such conclusions are justified by way of reasoning (Doppelt, 1998:105; Giere, 1984:26; Harre, 1965:11; Leherer & Wagner, 1983 & Pitt, 1988:7). The structure of a research report thus consists mainly of conclusions and reasons for such conclusions (Booth, Colomb & Williams, 1995:97). From this it appears that justification by means of reasoning is a standard procedure in research and research reports. Despite the fact that the logic of research is based on reasoning, that the justification of research findings by way of reasoning appears to be standard procedure and that the structure of a research report comprises arguments, the evaluation or assessment of research, as described in most textbooks on research methodology (Burns & Grove, 1993:647; Creswell, 1994:193; LoBiondo-Wood & Haber, 1994:441/481) does not focus on the arguments of research. The evaluation criteria for research reports which are set in these textbooks are related to the way in which the research process is carried out and focus on the measures for internal, external, theoretical, measurement and inferential validity. This means that criteria for the evaluation of research are comprehensive and they should be very specific in respect of each type of research (for example quantitative or qualitative). When the evaluation of research reports is focused on arguments and logic, there could probably be one set of universal standards against which all types of human science research reports can be assessed. Such a universal set of standards could possibly simplify the evaluation of research reports in the human sciences since they can be used to assess all the critical aspects of research reports. As arguments from the basic structure of research reports and are probably also important in the evaluation of research reports in the human sciences, the following questions which I want to answer, are relevant to this paper namely: What are the standards which the reasoning in research reports in the human sciences should meet? How can research reports in the human sciences be assessed or evaluated according to these standards? In answering the first question, the logical demands that are made on reasoning in research are investigated. From these demands the acceptability of the statements, relevance and support of the premises to the conclusion are set as standards for reasoning in research. In answering the second question, a research article is used to demonstrate how the macro- and micro-arguments of research reports can be assessed or evaluated according to these standards. With evaluation it is indicated that the aspects of internal, external, theoretical, measurement and inferential validity can be evaluated according to these standards.
