Cochlear implants (CIs) have revolutionized the field of audiology, providing a life-changing solution for children with bilateral profound hearing loss. Expanding criteria has allowed children with significant unilateral hearing loss (UHL) to benefit from this technology as well. The practice is not without controversy, however. While we have…

Critical analysis is universally advocated as a key goal of science teaching. In that context, the article explores the responses of beginning teachers (BTs) to explanations used in science education. Specifically, the study asks how BTs can be helped to ground their pedagogical choices in a critical analysis of explanations introduced during…

In this paper, we aim to highlight the characteristics of neuro-linguistic programming (NLP) and suggest possible directions for future research and study. The majority of NLP studies argue for more rigorous empirical support and standardised regulatory governance, in order to overcome academic biases and general misunderstandings. However, its…

This paper gives a brief summary of Halliday's theory of how children learn to talk, illustrating the development of children's language from the microfunctions through the macrofunctions and into the metafunctions of adult language. The paper points to a possible source of the misinterpretation of Halliday's theory in the work of Frank Smith…

Gap reasoning is an inappropriate strategy for comparing fractions. In this article, Patrick Sullivan and Joann Barnett look at the persistence of this misconception amongst students and the insights teachers can draw about students' reasoning.

Cara, a seventh-grade student with learning disabilities (LD) in mathematics, believes that the ratio 2:3 is equivalent to 4:5 because there is a difference of one between the two numbers in each ratio and there is a difference of two between corresponding numbers in the two ratios (2 + 2 = 4 and 3 + 2 = 5). This misconception affects her ability…

Ratios and proportions are foundational to student understanding across multiple topics in mathematics and science. In mathematics, they are central to developing concepts and skills related to slope, constant rate of change, and similar figures, which are all fundamental to algebraic concepts and skills. This article examines the importance of…

The use of "radar charts" is an increasingly popular way to present spatial data in a visually interesting format. Some authors recommend using "filled radar charts" to compare the performance of observational units. Filled radar charts are not appropriate for such comparisons because the size of the area within the polygon is not invariant to the…

This paper presents heuristic explanations of factor scores, structure coefficients, and communality coefficients. Common misconceptions regarding these topics are clarified. In addition, (a) the regression (b) Bartlett, (c) Anderson-Rubin, and (d) Thompson methods for calculating factor scores are reviewed. Syntax necessary to execute all four…

In online educational systems we can easily collect and analyze extensive data about student learning. Current practice, however, focuses only on some aspects of these data, particularly on correctness of students answers. When a student answers incorrectly, the submitted wrong answer can give us valuable information. We provide an overview of…

The examination of cross-classified category data is common in evaluation and research, with Karl Pearson's family of chi-square tests representing one of the most utilized statistical analyses for answering questions about the association or difference between categorical variables. Unfortunately, these tests are also among the more commonly…

A thematic course called "Climate Change: Chemistry and Controversy" was developed for upper-level non-STEM students. This course used the socioscientific context of climate change to teach chemical principles and the nature of science. Students used principles of agnotology (direct study of misinformation) to debunk climate change…

The Carnegie Project on the Education Doctorate (CPED)--which the College of Education and Social Services (CESS) at the University of Vermont has actively been involved in since 2007--has invited us to think carefully about our EdD doctoral program and its role in the improvement of schools and society. Although the EdD program in Educational…

This article discusses a particular type of concordance table and the potential for test score misuse that may result from employing such a table. The concordance that is discussed is typically created between scores on different, nonequatable versions of a test that share the same or close to the same test title. These concordance tables often…

In this article, we provide a discussion on our revision method (termed "prescriptive tutoring") aimed at revealing students' misconceptions and misunderstandings by getting them to solve physics problems with an anonymous partner via the computer. It is currently being implemented and evaluated in a public secondary school in Singapore,…
