Argues that educational researchers analyzing multilevel data must identify appropriate sets of research questions at and within various levels of analysis and must specify appropriate models for analyzing the data. Covers problems, terminology, and measurement and statistical issues associated with multilevel research. (PGD)

As complex, sophisticated techniques for statistical analysis become easier to obtain and apply, it becomes increasingly critical for researchers to examine their data prior to analysis to ensure that the data are suitable for analysis. Exploratory Data Analysis provides methods for subjecting data to appropriate pre-analysis scrutiny. (PGD)

Written in response to an article (Horn, 1983) that appeared in special Developmental Behavioral Genetics section of CHILD DEVELOPMENT (Volume 54), this commentary (1) notes some issues concerning Horn's analysis and interpretation of data and (2) highlights the potential for interpretational bias in behavior genetics research. (Author/BE)

In this rebuttal to Walker and Emory's commentary (also in this issue), Horn argues that the issue of the influence of environment on the average IQ of adopted children was well discussed in his article (Volume 54 of CHILD DEVELOPMENT). (BE)

Androcentrism, the practice of viewing the world and shaping reality from a male perspective, has created biases in organizational behavior theory that have led to imprecise, inaccurate, and imbalanced scholarship. This article analyzes gender bias in theories and studies in organizational behavior and discusses implications of the findings. (PGD)

Aims to clarify the distinction between elicitation and reinforcement discussed in Bloom (1984); to make explicit theoretical and methodological assumptions about the experimental analysis of infant behavior as shown in components of Poulson (1983); and to clarify differences in interpretation of other infant vocal conditioning research.…

Discussion of conceptual and methodological aspects of reading intervention research focuses on nine specific design limitations of previous intervention research; ways to measure and analyze change as a function of development, treatment intervention and ecological influences; assumptions of individual growth models; and advantages, conditions,…

Suggest practical procedure for estimating number of subjects that need to be screened to obtain sample of fixed size that meets multiple correlated criteria. Procedure described is based on fact that least-squares regression provides good quadratic fit for Monte Carlo estimates of multivariate probabilities when they are plotted as function of…

The methodology of many studies that have identified specific genetic loci for disorders associated with mental retardation is criticized as failing to demonstrate an association between the behavior phenotype and the genetic marker. A more appropriate methodology using a multitrait-multimethod approach is suggested. (Author/JDD)

Discussed is the question of whether "heavy" neutrinos really do exist based on the evidence supplied by four research groups. The implications of its existence on the disciplines of particle physics, astrophsyics, and cosmology are discussed. Background information on the different types of neutrinos is provided. (KR)

Emphasising the level of the observation of university configurations and the example of academic entrepreneurship, the author analyses the drivers of economic returns of public research in France. Based on the study of national public policy in this field since 1999 and a general survey of the paths of researchers-entrepreneurs, the article…

This article explores some of the challenges and benefits of doing a dissertation with participants from a population to which I belong and on a topic some consider controversial, that of gay and lesbian educators. I describe the homophobia I experienced and how that homophobia affected my choice of topic, the research process, and my job…

In psychological and special education research, group comparison experimental designs are more often used than single subject experimental designs. However, the application of group designs poses many difficulties, such as the collection of large numbers of homogeneous subjects for a particular experimental condition, the averaging of individual…

Principles of program evaluation research are outlined so that bilingual education program coordinators can conduct methodologically acceptable program evaluations. The three basic principles of evaluation research are: identification of the program participants, definition of the program intervention, and assessment of program effectiveness.…

Social studies research has been criticized for sampling bias, inappropriate methodologies, incorrect or inappropriate use of statistics, weak or ill-defined treatments, and lack of replication and/or longitudinal follow-up. In an effort to ascertain whether past criticisms were true of current research as well, a review was conducted of 118…
