Content analysis of 364 articles in the Journal of Agricultural Education 1990-1999 indicated that a majority of studies did not mention nonresponse error as a threat to external validity, did not attempt to control for nonresponse error, or did not cite literature on handling it. Protocols to address nonresponse error were proposed. (Contains 24…

Describes the richness of Hollich et al.'s model of language acquisition. Presents concerns about focus on object words in word learning research, the phantom child in the model, and the missing affect in theories and research on word learning. Suggests that experimental work inspired by principles and constraints theory and observational work…

Suggests that the findings of Legerstee, Barna, and DiAdamo (2000) are most parsimoniously explained by associative learning and may not constitute a precursor to later understanding of intentionality. Argues for the importance of differentiating between associative and inferential processes and reviews evidence that the understanding of…

Discusses how student self reported gains or growth during college have become prominent dependent variables in much of the college impact research. Argues that, as typically used in existing studies, self reported gains or growth do not permit the same level of internal validity as does assessing gains with a pretest-posttest design. Suggests a…

Teaching in general and teaching of mathematics in particular are matters of great importance for contemporary society. Over the years, societies have established institutions in order to incorporate mathematics and science into the culture of society with the clear intention of encouraging a scientific vision of the world among the population.…

This article is about the possibilities of conducting research with children productively. Children may need suitable prompts, occasions, or media for their expression. The discussion begins with an overview of the challenges or dynamics researchers can experience with any participants in qualitative research in the constructivist paradigm. It…

This paper explores eight hypotheses regarding trends in CALL literature relative to research subjects: small number of subjects, overuse of questionnaires, limited time, lack of experience with the application, task type and CALL in general, and lack of training before and during the study. Based on a review of 78 articles from four CALL-oriented…

In this article, the author comments on an article by Dunn, Kadane, and Garrow, "Comparing Harm Done by Mobility and Class Absence: Missing Students and Missing Data." He believes the research reported in that article should serve as a model for future applications of Bayesian methods in important educational research problems. The author lauds…

A. W. Inhoff, R. Radach, and B. Eiter (see EJ750907) argue that the current version of the E-Z Reader model (A. Pollatsek, E. D. Reichle, & K. Rayner, see EJ750906) cannot explain 2 key findings in their data, and as a result, the assumption of words being attended to 1 at a time is likely to be false. In this rejoinder, the authors argue that…

The origin of the present comment lies in a failed attempt to obtain, through e-mailed requests, data reported in 141 empirical articles recently published by the American Psychological Association (APA). Our original aim was to reanalyze these data sets to assess the robustness of the research findings to outliers. We never got that far. In June…

Through numerical investigations, this paper studies examples of the forced Duffing type spring equation with [epsilon] negative. By performing trial-and-error numerical experiments, the existence is demonstrated of stability boundaries in the phase plane indicating initial conditions yielding bounded solutions. Subharmonic boundaries are…

This monograph critically examines the emerging discourse on quality associated with Education for All (EFA). It contends that EFA discourse has moved from a welcome and vital commitment to quality to its measurement without adequate consideration of what "quality" entails, particularly in the vital domain of pedagogy. Meanwhile, the…

A major challenge for researchers and educators has been to discern the effect of ICT use on student learning outcomes. This paper maps the achievements in Year 10 Science of two cohorts of students over two years where students in the first year studied in a traditional environment while students in the second took part in a blended or e-learning…

This is the first book to bring into focus the full scope of professional practice in educational leadership. This book probes the limitations of traditional research in fully comprehending the true nature of leadership, and points out how future research must be expanded to deal with understanding the complexity of educational leadership…

The impetus to broaden the scope of research education is not new. Since the 1970s, concern has been expressed about the suitability of research education as preparation for a research career outside academe. Universities have been criticized for producing over-specialized research graduates, who struggle to apply their expertise to new workplace…
