The question of truth as it relates to the teacher's role in the classroom raises not only issues of what and how we should teach, but challenges the very purpose of teaching. Since truth itself is a major question of phenomenology, the author chose to use the works of German philosopher Martin Heidegger for his phenomenological treatment of truth…

Equivalence-based instruction of college students was adapted for use in a commercial online course-delivery system, with written explanation replacing match-to-sample training. Outcomes rivaled those of previous studies in which students were taught in low-distraction settings through match-to-sample procedures that were controlled by custom…

This article discusses the concepts of "key ideas" and "memorability" and how they relate to the metric "width of a proof" put forward by the Fields medalist Timothy Gowers (2007) in a recent essay entitled "Mathematics, memory and mental arithmetic". The paper looks at the meaning of these concepts and…

As mobile technologies such as tablets and smartphones offer opportunities to view stories in digital format, young readers are faced with new challenges in the reading task. The authors conducted an exploratory study of digital story applications on a mobile reading device and found that digital story applications are capable of taking large…

The author states that raising her twins the Montessori way has made her life easy. Imagine two 1-year-olds eating entire meals on their own, setting their own tables by 20 months, and becoming potty-trained before 2. These are not statistics found in just one household.

2014 marks the 100th anniversary of the birth of Martin Gardner, a man whose writings helped inspire generations of young students to pursue a career in physics and mathematics. From his first to his last, and many in between, Gardner's publications often combined magic and science. A recurring theme was the clever use of physical principles…

Graphical model validation techniques for linear normal models are often used to check the assumptions underlying a statistical model. We describe an approach to provide "instant experience" in looking at a graphical model validation plot, so it becomes easier to validate if any of the underlying assumptions are violated.

The traditional assignment of oxidation states to organic molecules is problematic. Accordingly, in 1999, Calzaferri proposed a simple and elegant solution that is based on the similar electronegativities of carbon and hydrogen: hydrogen would be assigned an oxidation state of zero when bonded to carbon. Here, we show that X-ray photoelectron…

This study presents a new approach for transforming the latent representation derived from a Latent Semantic Analysis (LSA) space into one where dimensions have nonlatent meanings. These meanings are based on lexical descriptors, which are selected by the LSA user. The authors present three analyses that provide examples of the utility of this…

Background: With rates of autism diagnosis continuing to rise, there is an urgent need for effective and efficient service delivery models. Pivotal Response Treatment (PRT) is considered an established treatment for autism spectrum disorder (ASD); however, there have been few well-controlled studies with adequate sample size. The aim of this study…

Transfer of instructional technology knowledge for student-centered learning by teacher candidates is investigated in this study. Using the transfer of learning theoretical framework, a mixed methods research design was employed to investigate whether secondary teacher candidates were able to transfer the instructional technology knowledge for…

In this article, the authors report on the initial results of a mixed methods study that examined the beliefs that preservice teachers have about teaching real-world contexts, including those related to injustices, controversial issues, and children's home and cultural backgrounds. Data collection included a survey with 92 preservice Pre-K-8…

The inverted classroom allows more in-class time for inquiry-based learning and for working through more advanced problem-solving activities than does the traditional lecture class. The skills acquired in this learning environment offer benefits far beyond the statistics classroom. This paper discusses four ways that can make the inverted…
