Analysis of teacher-to-teacher talk provides researchers with useful information regarding the teaching profession and teachers' perspectives. This article provides a description of a method, with accompanying example, examining teacher-to-teacher talk by incorporating semantic modality and examining trends of its usage in a quantitative manner.…

Null hypothesis significance testing (NHST) is the most widely accepted and frequently used approach to statistical inference in quantitative communication research. NHST, however, is highly controversial, and several serious problems with the approach have been identified. This paper reviews NHST and the controversy surrounding it. Commonly…

Purpose: To examine the extent to which sentences retain their levels of spoken intelligibility relative to other sentences in a set (the "sentence effect") across different types of signal distortion. Method: The Central Institute for the Deaf (CID) sentences were rendered difficult to understand through the addition of broadband noise. These…

This study investigates cultural and communication medium effects on conversational argumentation in a decision-making context. Chinese and U.S. participants worked in pairs on two decision-making tasks via face-to-face (FtF) and instant messaging (IM). The analyses showed that Chinese participants tended to engage in potentially more complex…

Results of two studies indicate that the way in which Likert scale data are scored can make a difference when statistical significance tests are used. The studies raise a number of questions about the use of Likert scales in communication research. (GT)

Responds to Donald Dean Morley's reply (same issue). Discusses his claims about the use of multiple-message designs, the analysis of multiple-message designs, and generalization on logical grounds. (MS)

Considers two ways of conducting the search for generalizations about messages: (1) single-message research designs used with meta-analytic summaries; and (2) multiple-message designs treating messages as a random factor in the statistical analysis. Contends that the treatment of messages as a random factor is statistically appropriate. (MS)

Replies to Sally Jackson, Daniel O'Keefe, and Scott Jacobs' article (same issue), maintaining that randomness requirements can not be relaxed for generalizing from message samples, since systematic samples are not truly random. (MS)

Examines the role of culture as a key variable in public relations research and practice. Finds (1) American practitioners continue to practice one-way models of public relations; and (2) public relations practitioners who have collectivistic values tend to practice two-way models of public relations. Discusses implications for theory and…

Argues that generalizing to message populations by treating messages as a random variable is inappropriate for complex messages, and proposes meta-analytic techniques for investigating biases in message samples and other methodological factors that can limit generalizability of communication research. (MS)

Instructional applications of Q methodology (a set of procedures that can be used in studying the subjective nature of things) provide a means for teaching communication skills, analyzing thinking patterns, making comparative analyses, and structuring intrapersonal processes. Taking the best from quantitative and qualitative research methods,…

This review critiques the use of Lev Vygotsky's concept of the zone of proximal development (ZPD) in quantitative research that focuses on the role communication plays in learning. A study that makes claims in terms of the ZPD should include a pretest, a problem-solving activity, and a posttest. Without these minimal elements, researchers are not…

A quantitative study of a university chat reference service (online synchronous) addresses the following research questions: (1) What types of questions are being asked? (2) Who is asking the questions of the service? and (3) Did the customers get correct answers to their questions? All the transcripts (351) from January through August 2002 were…

Communication skills are important for children with developmental disabilities to be functional and independent in their own lives. This study examined influences of different types of listener feedback or breakdowns on repair behaviors of nonverbal children with disabilities during semi-structured opportunities at snack time. Three preschool…

For individuals who have complex communication needs and for the interventionists who work with them, the collection of empirically derived data that support the use of an intervention approach is critical. The purposes of this study were to continue building an empirically derived base of support for, and to compare the relative effectiveness of…
