There is unexamined potential for developing and testing rival causal explanations in the type of data that participant observation is best suited to create: descriptions of in situ social interaction crafted from the participants' perspectives. By intensively examining a single ethnography, we can see how multiple predictions can be derived from…

Studies by the National Association for Educational Progress found that English Language Learner (ELL) students perform poorly compared to other students on standardized mathematics exams. The research problem addressed how Sheltered Instruction Observation Protocol (SIOP) affected the instructional practices of high school mathematics teachers.…

Reviews the seven papers presented at a symposium entitled "Perennial Issues in Qualitative Research," part of the Annual Meeting of the American Educational Research Association (San Francisco, California, 1986), and included in this issue. Discusses the demonstrated usefulness of qualitative methods in educational research, and also…

Explores problems involved in the quantitative verification of independent variables in investigations of the effects on student outcomes of planned variations in instructional behavior. Specifically addresses (1) gathering of data through direct systematic observation, and (2) analysis of those data through the use of inferential statistics. (GC)

Classroom research is caught between lack of rigor and lack of richness. When multiple classrooms are used, and when the performance of different groups or levels of students is regarded as "repeated measures" (or split plots) and analyzed accordingly, much of the descriptive richness of the interactions may be regained. (Author)

In a nonrandomized or observational study, propensity scores may be used to balance observed covariates and trajectory groups may be used to control baseline or pretreatment measures of outcome. The trajectory groups also aid in characterizing classes of subjects for whom no good matches are available and to define substantively interesting groups…

An investigation was conducted of the characteristics of two estimation procedures and corresponding test statistics used in the analysis of completely randomized factorial experiments when observations are lost at random. For one estimator, contrast coefficients for cell means did not involve the cell frequencies. For the other, contrast…

This commentary focuses on the application of D. Rogosa and G. Ghandour's work to observational research on classroom processes. Rogosa and Ghandour have shown that the short length of an observation is typically the dominant source of error. Investigators should conduct observations for as long as possible. (SLD)

Using observational data on classroom teachers, statistical procedures are presented for studying two questions on the stability of teacher behavior over time: (1) Is the individual teacher's behavior consistent? and (2) Are individual differences among teachers consistent? Approaches and methods of previous temporal stability studies are…

All social science serves some agenda: social science research is a value-bound, value-determined, context-situated, and ideologically loaded enterprise. Each researcher makes choices in the following areas, whether tacitly, implicitly, or deliberately: (1) a paradigm choice, either conventional (rationalistic) or emerging (naturalistic); (2) the…

This paper discusses the problems of gathering and analyzing data on classroom behaviors. The difficulties involved in using the common pretest-posttest experimental design are described. To grapple with these problems, a study was conducted on the effect of environmental changes on student behavior, employing a time-series design and time-series…

Considers both qualitative and quantitative research approaches on second language learning, with focus on second language classroom research. Concludes that both approaches are relevant to determining the important variables to investigate and the relationships those variables have to second language learning outcomes. (Author/CB)

Three common methodological problems in the analysis of observational data include: (1) failure to base degrees of freedom for the analysis on the appropriate sampling unit; (2) the validity of the design and data are inconsistent with the generalizations reached; (3) the statistic used to calculate coder reliability is often inappropriate and…
