This commentary discusses the issue of small samples in instructed second language acquisition research. We discuss the current state of affairs, and consider the disadvantages of small samples. We also explore other considerations regarding sample size, such as research ethics and ecological validity. We present a range of recommendations for…

Education researchers working in sub-Saharan Africa have recently and rapidly expanded the availability of evidence related to the impact of educational interventions on learning outcomes, particularly in preprimary and lower primary education (Ganimian & Murnane, 2016; McEwan, 2015; Popova, Evans, & Arancibia, 2016). Awareness that…

The authors respond to the commentaries on a series of articles (in the March 2009 issue of "Educational Researcher") that discuss the challenges associated with measuring reading instruction. The authors argue that the teaching of reading is a complex, multifaceted phenomenon best studied through a variety of overlapping and complementary…

The existence, preponderance, and stability of misconceptions related to evolution continue as foci of research in science education. In their 2006 study, Geraedts and Boersma question the existence of stable Lamarckian misconceptions in students, challenging the utility of Conceptual Change theory in addressing any such misconceptions. To support…

This paper presents a critical analysis of two recent studies on error correction, Ellis, Sheen, Murakami, and Takashima (2008) and Bitchener (2008) and argues that neither study constitutes evidence for error correction based on discussion of the comparability of participants, design issues, and analysis flaws in both studies. The paper further…

Using the British "Index to Theses", we found forty-seven Ph.D.s relating to second and foreign language learning and/or teaching defended in English universities in 2006. Objective criteria led us to fourteen theses which had investigated both teaching and learning. Over half of these adopted a process-product research design with the…

The educational system has not been particularly successful in teaching thinking skills. In order to do so, it is necessary to identify what thinking skills are and understand their development. Current research and design of future research are discussed, as is the problem of transfer. (MT)

Discusses common beliefs and flaws in classroom research. Distinguishes among three kinds of empirical educational investigations. Suggests research designs which are considered to be sensible, selective, sound, sensitive, and simple. Describes designs using multiple classrooms for instructional-intervention experiments. (KS)

One effective method to improve the learning of science is through case study teaching. Teachers use realistic or true narratives to provide opportunities for students to integrate multiple sources of information in an authentic context, and may engage students with ethical and societal problems related to their discipline. However, little…

In this commentary, I summarize my own research with colleagues to affirm Dr. Gersten's call for considering design experiments prior to conducting intervention research. I describe how design experiments not only can inform teaching and the learning of innovative approaches, but also hold the promise of effectively bridging the…

Qualitative research procedures may be characterized by the practice of empiricism that is sensitive to individual perspectives of reality. The many techniques that may be used are malleable and situation-specific in their design--contingent on those aspects of social phenomena that are chosen to be studied. Practical curriculum design for…

A review of the literature and personal action research leads the authors to question the relevance of much of the advice offered to students concerning study skills. They offer a different teacher-learner framework for those teachers and students who wish to gain insight into, and control over, their own teaching/learning. (Author/CT)

The arguments for and against Thomas Kuhn's paradigmatic thesis are presented in this paper as a means of discussing the appropriateness of Kuhn's thesis to the emerging composition discipline. Section one of the paper introduces the topic, noting how the term paradigm is used in composition to define a system of widely shared values, beliefs, and…

Presents the author's views concerning the nature of educational intervention in learning disabilities. Considers ethical issues, research design, and measurement of change. Discusses the barriers to conducting intervention studies and methods for dissemination of the research findings. (DB)

When the editors of The Voice of Evidence in Reading Research, Ms. McCardle and Ms. Chhabra, decided to edit a book and to invite authors to contribute to it, they wanted it to be a book for teachers. As stated in the first chapter, their motivation was to empower teachers to judge research worthiness for themselves. They feel that it is important…
