Despite advances in software development, symmetry-related topics are among the most important yet confusing concepts in crystallography training for chemistry students who routinely use small-molecule crystallography in their scientific study. The case-based learning approach is very effective in stimulating students' interests in self-exploring…

Interviewing 31 individuals at a public research institution we examine students' assumptions about compositional social class diversity (CSCD) on campus and the ways various dimensions of climate for social class diversity interplay with students' awareness of CSCD. Findings reveal the assumptions that guide students' interpretation of CSCD on…

The Reaction Coordinate Diagram Inventory (RCDI) was developed to measure chemistry students' thinking and confidence when interpreting the kinetic and thermodynamic information encoded within reaction coordinate diagrams (RCDs). The RCDI was designed based upon analyses of qualitative data collected in semi-structured interviews with general…

Interactions around unexpected, incorrect, or dis-preferred responses can be powerful sites of learning for both teachers and students. The information that teachers uncover through probing student thinking can then guide their pedagogical response. We report on a study of prospective teachers' skills and capabilities around a particular problem…

This study investigated family perceptions of Autism Spectrum Disorder (ASD) in China. A survey with open-ended questions assessing knowledge of ASD and its causes was distributed via nine ASD organisations across five different cities in Southern China. Results were analysed from a total of 104 Chinese caregivers who reported on their children or…

This article explores relationships of youth power in a set of threads leading to the potential of today's youth activism to combat the climate crisis. Following an introduction featuring Sweden's Greta Thunberg, the threads are these: First from an American context is history of youth development, with one emphasis on the construction of…

Jawaharlal Nehru's contribution in pioneering the concept of scientific temper in India is widely acknowledged, and his legacy has had an influence on Academia, Education policy and popular science movements in the country. But in the last decade, the new age social media revolution has seen a renaissance of right wing nationalism, backed by an…

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…
