Descriptive statistics involves summarizing and organizing data so that they can be easily understood. Even though these are basic and simple concepts, many applied science students have misconceptions about their use in applied experiments in the laboratory. Students usually receive limited or no training in how to understand the meaning of the…

This research aims to investigate the pedagogical content knowledge (PCK) of prospective mathematics teachers on the subject of limits, based on the two components of PCK: the knowledge of student understanding and the knowledge of instructional strategies. The research sample comprises 33 fourth-year prospective Mathematics teachers (known…

This study investigates climate change perceptions of secondary science teachers in a Blue state and a Red state. A total of 832 secondary science teachers, 456 from California, and 376 from Texas public schools responded to an online questionnaire regarding their climate change perceptions. Findings indicate that a significant proportion of…

Jesus' appearance is not recorded in the New Testament, apart from some incidental mentions of his clothing. Nevertheless, his appearance is the most recorded feature in the history of world art. None of these images is based on primary sources; most, especially the most popular and influential images, tend to portray Jesus in the guise of a…

Introductory chemistry textbooks often present valence bond (VB) theory as useful, but incorrect and inferior to molecular orbital (MO) theory, citing the electronic structure of O[subscript 2] and electron delocalization as evidence. Even texts that initially present the two theories on equal footing use language that biases students toward the…

We are living in an era where reality, truth, and facts are being turned upside down and inside out. Fake news and falsehoods are being spewed out in increasing exponential rates. I was prompted to do something about the propensity of fake news through post-truth discourse and designed an undergraduate course that I titled: Bullshit, Fake News,…

I posit that while U.S. public school teachers who use assimilation pedagogy apparently believe they open educational opportunities for immigrant children, they instead cause immigrant children to lose their identities by alienating them from their cultures, families, and themselves. To demonstrate my claim, I analyze an educational autobiography…

Although our students correctly define the terms p-value, Type I and Type II errors, they sometimes misinterpret results from real data. In this work we present an assignment intended to clear up these misconceptions.

Prior research indicates that student teachers frequently have misconceptions about multimedia learning. Our experiment with N = 96 student teachers revealed that, in contrast to standard texts, refutation texts are effective to address misconceptions about multimedia learning. However, there seems to be no added benefit of making…

Research on second language (L2) acquisition in the generative tradition (GenSLA) addresses the nature of interlanguage competence, examining the roles of Universal Grammar, the mother tongue and the input in shaping the acquisition, representation and use of second languages. This field is sometimes dismissed by applied linguists as irrelevant…

This study examined the extent to which college algebra instructors employ pedagogical practices previously found to assist students master difficult STEM content material and address their own previous math deficits. Faculty classroom behaviors were assessed with a modified version of the Generalized Observation and Reflection Platform (GORP).…

Students have misconceptions about many scientific topics they encounter in the classroom--such misconceptions are especially rife in subjects with counterintuitive concepts. Several studies have copiously documented students' misconceptions in different science domains. Research shows that students' misconceptions can be resistant to change and…

In their thought-provoking article, Giacalone and Promislo point to some problematic ideas in management education such as the adoration of materialism and competition or the notion of the economic model as a natural law. But do students really develop such ideas because they were misinformed by their teachers? Misinformation implies that what is…

Fragile understanding is where new learning begins. Students' understanding of new concepts is often shaky at first, when they have only had limited experiences with or single viewpoints on an idea. This is not inherently bad. Despite teachers' best efforts, students' tenuous grasp of mathematics concepts often falters with time or when presented…

Integrating the nature of science (NOS) into textbooks is one of the challenges in science curricula. This case study assessed the issue based on a sample of high school biology textbooks in Mainland China. We quantitatively compared changes in the extent, quality, and distribution of NOS representations between 2004 and 2019 editions. Three main…
