Each year, policymakers, educators, and the general public engage in debates around the statewide average teacher pay figure that the North Carolina Department of Public Instruction (DPI) publishes on its website and reports to the National Education Association. These debates take up the important consideration of whether or not teachers are…

This paper presents a critical analysis, from the point of view of a statistician, of the methodology used by Hattie in "Visible Learning," and explains why it must absolutely be called pseudoscience. We first discuss what appears to be the intentions of Hattie's approach. Then we describe the major mistakes in "Visible…

Teaching is the process of conveying knowledge and skills to learners. It involves preventing misunderstandings or correcting misconceptions that learners have acquired. Thus, effective teaching relies on solid knowledge of the discipline, but also a good grasp of where learners are likely to trip up or misunderstand. In programming, there is much…

The "Brown v. Board of Education" (1954) Supreme Court decision ruled that segregated schools were unequal and unconstitutional. Since Brown's ruling, scholars have questioned whether African American children have benefitted from school desegregation and subsequent school reform initiatives. In spite of several post-Brown school reform…

The level of educational attainment in the United States is a central focus of public policy. The Obama administration, some states, large national foundations, and other organizations have set near-term goals to increase the number of Americans with college degrees. Achieving these goals is likely to involve a combination of increasing…

Shortly after we published "Addressing Flawed Research in Developmental Education" (2012) in the "Journal of Developmental Education," Thomas Bailey, Shanna Smith Jaggars, and Judith Scott- Clayton from the Community College Research Center (CCRC) wrote a response rebutting several of our claims. Though their response corrects…

In response to the wide-scale proliferation of "the cone of learning"--a fanciful retention chart confounded with Dale's Cone of Experience--the authors make four major claims debunking this fantasy and provide documentary evidence to support these claims. The first claim is that the data in the mythical retention chart do not make…

Critics have been attempting to debunk the mythical retention chart at least since 1971. The earliest critics, David Curl and Frank Dwyer, were addressing just the retention data. Beginning around 2002, a new generation of critics has taken on the illegitimate combination of the retention chart and Edgar Dale's Cone of Experience--the corrupted…

The authors are attempting to set the record straight regarding the sources frequently cited in the literature of the mythical retention chart and the corrupted Dale's Cone. They point out citations that do not actually connect with relevant works; provide correct citations of sources that are often cited erroneously; add references for overlooked…

Background: Historically, significant advances in scientific understanding have followed advances in measurement and observation. As the resolving power of an instrument increased, so have gains in the understanding of the phenomena being observed. Modern interactive systems are potentially the new "microscopes" when they are…

While population mobility is a fundamental component of the lived experience of many Australian Aboriginal and Torres Strait Islander families, the ways in which educators and education systems respond (or fail to respond) to mobility demonstrates that there is very little understanding of this social and cultural phenomena. At the local school…

Typically, achievement gaps between groups of students are measured as either differences in average scores or differences in proficiency rates. But, practitioners, policymakers, and researchers have long recognized that these approaches don't tell the whole story. Average scores, for example, are good at summarizing trends but can mask real…

Misconceptions of chemistry and chemical engineering university students concerning instrumental analysis have been established from coordinated tests, tutorial interviews and laboratory lessons. Misconceptions can be divided into: (1) formal, involving specific concepts and formulations within the general frame of chemistry; (2)…

An exploratory study was conducted with 23 organic chemistry educators to discover what general chemistry concepts they typically review, the concepts they believe are fundamental to introductory organic chemistry, the topics students find most difficult in the subject, and the misconceptions they observe in undergraduate organic chemistry…

Due to the variations of design and protocol in qualitative inquiry, researchers may inadvertently create problems for themselves in terms of the trustworthiness of their research. Miscommunication between participants and researchers can especially arise from the unique and unpredictable nature of human dynamics. In this paper I contend that such…
