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…

Young children are familiar with astronomical phenomena from everyday life, such as the movement of the celestial bodies or the shift from day to night. The present study examines the extent to which kindergarten students understand abstract concepts related to celestial bodies and processes (such as gravity and time), and whether they change…

This study presents a characterization of prospective early childhood teachers' (ECEPTs) and prospective elementary school mathematics teachers' (EMEPTs) concept images and concept definitions of triangles through a defining task and an example generation task. Data consisted of 62 EMEPTs' and 72 ECEPTs' written statements for the definition of a…

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,…

The aim of the present study is to determine the elementary pre-service mathematics teachers' understanding on solids. For this purpose, pre-service teachers' definitions and drawings of these objects were examined. Qualitative research method was used. A written questionnaire consisting of sixteen open-ended and multiple-choice questions was…

Conflicting knowledge claims regarding complex issues have become readily available through networked digital media, and the introduction of Internet access to classrooms has provided opportunities for accessing a huge number of sources. Science education plays an important role in providing students opportunities to seek and evaluate information…

Phylogenetic trees are important tools for teaching and understanding evolution, yet students struggle to read and interpret them correctly. In this study, we extend a study conducted by Catley and Novick (2008) by investigating depictions of evolutionary trees in US textbooks. We investigated 1197 diagrams from 11 German and 11 United States…

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 many institutions and government agencies count degrees as the sole measure of determining departmental or program viability, this method fails to consider other factors such as how many students who are within programs are present to replace students who graduated from those programs or how many credit hours were generated in the area.…

We are witnessing what can only be called an anti--critical thinking trend in contemporary society. In this brief essay I want to describe how and why critical thinking is in crisis, and what this means for the promotion of critical thinking as an educational aim. Several of my examples show how this crisis has distorted the public debate over…

Objective: This study examined rates and predictors of peer recommendation of resources after disclosure of actual and hypothetical unwanted sexual experiences. Participants: Private university students without a history of college sexual assault were recruited in 2 groups. One was a group of peers who had received an assault disclosure (N = 122)…

Designing and interpreting controlled experiments are important inquiry skills addressed in many current science curricula. The relevant skills associated with the design and interpretation of controlled experiments are summarised under the term control-of-variables strategy (CVS). Research on elementary school students' CVS skills shows that they…
