This article looks at the American Dream as a merit narrative to understand how it supports barriers to educational success for educators working to improve the lives of students in urban schools. Hard work/perseverance and individualism are interrogated as components of merit narratives used to sustain the American Dream. We analyze data from six…

This study aims to compare the impact of the Dual Situated Learning Model (DSLM) and conventional instructions in improving High School Students' understanding of chemical equilibrium concepts and the prevention of possible misconceptions. The study utilized a quasi-pretest-posttest control and experimental group design with two classes of XI SMAN…

Competition is a ubiquitous component of American culture and in many US physical education programs. In this article, five myths associated with competition are dispelled: (1) Everyone likes competition, (2) Competition is motivational, (3) Competition is fun, (4) Competition promotes physical activity, and (5) Competition prepares children for…

Recollection is constructive and prone to distortion, but the mechanisms through which recollections can become embellished with rich yet illusory details are still debated. According to the conceptual fluency hypothesis, abstract semantic or conceptual activation increases the familiarity of a nonstudied event, causing one to falsely attribute…

Engineering students in control courses have been observed to lack an understanding of equilibrium and stability, both of which are crucial concepts in this discipline. The introduction of these concepts is generally based on the study of classical examples from Newtonian mechanics supplemented with a control system. Equilibrium and stability are…

Previous research reported that in processing structurally ambiguous sentences comprehenders often preserve an initial incorrect analysis even after adopting a correct analysis following structural disambiguation. One criticism is that the sentences tested in previous studies involved referential ambiguity and allowed comprehenders to make…

Understanding the decimal system is challenging, requiring coordination of place-value concepts with features of whole-number and fraction knowledge (Moloney and Stacey 1997). Moreover, the learner must discern if and how previously learned concepts and procedures apply. The process is complex, and misconceptions will naturally arise. In a…

In June 2013, the third World Evolution Summit convened on San Cristóbal, hosting scientists from around the world (Paz-y-Miño-C and Espinosa 2013)--neither the first nor likely the last gathering of biologists on these remote islands. Clearly, both locals and an international audience perceive Galápagos as figuring prominently in discourse about…

Children's books about the Thanksgiving holiday offer a superlative example of America's supposedly innocent interactions with "Indians." In this essay, we describe how representations of "Indians" in children's Thanksgiving books are often used to promote a Manifest Destiny ideology, we correct basic "facts" about…

The complex approximation is widely used in the framework of the Ligand Field Theory for explaining the optical properties of crystalline coordination compounds. Here, we show that there are essential features of these systems that cannot be understood with the usual approximation that only considers an isolated complex at the correct equilibrium…

Reduction is one of the key techniques used for problem-solving in computer science. In particular, in the theory of computation and complexity (TCC), mapping and polynomial reductions are used for analysis of decidability and computational complexity of problems, including the core concept of NP-completeness. Reduction is a highly abstract…

In this article, Dominic Griffiths reflects upon the current cultural gap between those who locate themselves as working "on the inside" of the world of "special educational needs" and the "inclusion movement" and those who might be described as "mainstream classroom teachers". Griffiths warns of the dangers…

For decades, students have been encouraged to use "Please Excuse My Dear Aunt Sally" as a means of learning the order of operations. Teachers unfamiliar with the Aunt Sally mnemonic are perhaps more familiar with a mnemonic such as PEMDAS. Each mnemonic is intended to convey "parentheses, exponents, multiplication, division,…

Many studies mentioned the deductive nature of Mathematical Induction (MI) proofs but almost all fell short in explaining its potential role in the formation of the misconceptions reported in the literature. This paper is the first of its kind looking at the misconceptions from the perspective of the abstract of the deductive logic from one's…

Educators often have the feeling that they are finding it harder and harder to reach their students. That is why they are so feverishly interested in smartboards or learning platforms or anything new on the market that might help. Every new tool seems like a possible solution, although sometimes educators really don't know what the problem is or…
