We report on an investigation of student thinking about steady-state pipe flow of an incompressible fluid. About 250 undergraduate engineering students were given a test consisting of two hydrodynamics questions, combining multiple-choice format with subsequent open-ended explanations. There is substantial evidence that students have difficulty…

With an awareness of the considerable discomfort of graduate students in grasping the crux of key concepts of voltammetry and its variants, I present an inexpensive and user-friendly hands-on setup based on the fabrication of a rotating platinum electrode to facilitate teaching the tenets and applications of hydrodynamic voltammetry (HV). Readily…

A laboratory project to introduce upper-level undergraduates to Pd-catalyzed C-N [sigma]-bond forming reactions is described. The exercise involves evaluation of monodentate phosphine ligands and solvents for the Buchwald-Hartwig coupling of 4-chloro-or 4-bromo-anisole with morpholine. Students gain experience in the synthesis of a biarylphosphine…

This paper is a critical systematic literature review of empirical work on creative pedagogies from 1990 to 2018. It responds to the increased international attention being afforded creativity and creative pedagogies in research, policy and practice and examines the evidence regarding creative pedagogical practices and the potential impact of…

This paper reports a demonstration of a 90 min on-demand class where a chemical experiment is performed to educate nonscience majors on surfactants. First-year undergraduate students perform the water ball in a water bottle experiment at home and learn about the structure and properties of organic compounds in the demonstration. The experiment is…

The study aims to learn that they want to reflect on their reflective thoughts and reveal how they reflect what they have learned. Reflective thinking, one of the higher-order thinking skills, enables students to learn more easily and permanently. Students with high reflective thinking skills will be more successful both in their academic and…

This paper aims to elicit the different conceptions of Socioscientific Issues (SSI) in formal, non-tertiary STEM lessons. An examination of recent publications in the field of science education was conducted to elicit the most common conceptions of SSI as per the components of STEM lessons, namely: purpose, contents, teaching and learning…

This research aimed to explore the conceptual structure of chemical equilibrium in upper-secondary school students using factor analysis. Research on chemistry education has shown that chemical equilibrium is an important but difficult-to-understand topic. Exploring the conceptual structure of chemical equilibrium among students will help…

Fostering conceptual understanding in mathematics classrooms is an important goal in mathematics education. To support this goal, we need to be able to diagnose and assess the extent to which students have conceptual understanding. In this study we employed a problem-posing task and a problem-solving task in order to diagnose and assess preservice…

This study proposes and explores "STREAM", a new concept that includes recreation to STEAM (Science, Technology, Engineering, Art, and Mathematics) to improve STEM education. Fifteen college students participated in a recreational activity created by the authors to teach the concept of Distributed Ledger; the students did not have prior…

Iodonium zwitterions are hypervalent iodine compounds in which the iodine center binds to two substituents and carries a positive formal charge which is compensated by a negative charge within the same molecule. Under thermodynamic conditions, iodonium zwitterion sallow concerted nucleophilic aromatic substitutions to be performed, followed by…

The biological world includes many negatively valenced activities, like predation, parasitism, and disease. Do children's books cover these activities? And how do parents discuss them with their children? In a content analysis of children's nature books (Study 1), we found that negatively valenced concepts were rarely depicted across genres and…

Feedback provided by mathematics teachers usually addresses procedural skills and, to a much lesser extent, other competencies such as conceptual understanding or engagement in mathematical practices. As most previous literature has studied feedback provided on homework or video prompts, how teachers provide such feedback in the classroom is…

In this exploratory study, a sample of 20 four-year-olds took part in structured interviews in order to assess their biological knowledge of how the human body processes a food that they perceived to be fattening. There were two main outcomes to the study. First, the sample demonstrated knowledge of the digestive processes of ingestion,…

This study aims to examine the impact of affective states and affective shifts on ideation and evaluation of creativity. Affects were induced by a two-stage imagination procedure of recalling autobiographical experiences. Three periods of divergent thinking were measured to represent the participants' creative ideation at different times. Creative…
