This work investigates science major students' misconceptions about "force and motion." Stratified-convenience sampling method has been conducted on 232 Moroccan high school students. Using Force Concept Inventory (FCI), we examined all known misconceptions listed in the original article by Hestenes et al. (1992, "Phys. Teach."…

The use of animations, simulations, and remote lab experiments has taken a new turn during the pandemic. When teaching introductory-level physics courses, the simulations and animations play an important role. Carefully designed simulations assist students visualize real-life situations and help understand complex physics concepts behind them.…

This program focused on exploring science and mathematics content and pedagogy for elementary and middle grades, pre-service teachers, including those students preparing to teach in regular and exceptional education classrooms. A total of 31 individuals participated in one or more workshops. The activities contained within the Lego BricQ Motion…

Identifying and naming inorganic compounds is sometimes a challenge for many first-year chemistry and engineering students; however, these difficulties can be overcome after extensive practice using homework sets based on naming inorganic compounds or applying inorganic nomenclature rules. Werner is a card game in honor of Professor Alfred Werner…

Catalysis and catalytic cycles are widely used in both research and industry. The addition of a catalysis experiment into the undergraduate laboratory curriculum is important and necessary training to expand student learning. Here, an experiment demonstrating iron-based tandem catalysis was developed and implemented in an organic chemistry course…

An educational lattice model is proposed for the investigation of the influence of the density and indirectly of the pressure on the chemical equilibrium of the ideal gas phase reaction A [equilibrium] 2B. The model can be introduced by a board game simulating a stochastic process. This game can also be used to set up a corresponding computer…

FINDIF is a Windows application that numerically solves the one-dimensional (1D) Schrödinger equation and displays the eigenstates, eigenvalues, and probability density of the system. FINDIF accepts both nonperiodic and periodic 1D potential energy functions as input and uses the finite difference method to evaluate the energy of the quantum…

This research developed learning activities for students to explore and connect the concepts of acid-base titration, equivalence points, pK[subscript a], and molar absorption coefficients. Polyphenolic compounds consisting of p-coumaric acid (CMA), caffeic acid (CFA), and 3,4,5-trihydroxycinnamic acid (3,4,5-THCA) were selected as study models.…

A straightforward procedure for the synthesis of (Ph[subscript 3]P)[subscript 3]CuCF[subscript 3], a robust, air-stable trifluoromethylating agent, is reported herein. This preparation can be completed in a single 3 h laboratory session and typically provides ample yields (~79--86%) and high purity (>90%). The target complex is characterized by…

Here, we present a ten-year assessment of core concept retention, with an emphasis on evolution, by senior biology majors at a small, private liberal arts college. For concepts that are regularly revisited throughout the biology curriculum, we found that knowledge retention was robust. However, for concepts that are encountered only during the…

Despite a decline in sexist language, traditional gender beliefs remain embedded in the scientific literature on reproductive biology and consequently continue to distort knowledge, encumber the learning process, and reinforce gender essentialism. This article analyzes the enduring force of gender stereotypes in Italian middle school science…

Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory…

Asking students to explain why phenomena occur at a molecular level is vital to increasing their understanding of chemistry concepts. One way to elicit students' mechanistic reasoning and guide construction of knowledge is through Writing-to-Learn (WTL), which is a promising approach for students in organic chemistry courses. In the design of WTL…

Environmental education is becoming a growing area of interest in early childhood education. In France, more time is given to environmental education activities in the preschool curriculum. Yet, there is a risk of narrowing preschool environmental education only to carry out pro-environmental behaviours, without giving pupils the opportunity to…

To foster students' meaningful learning of science, we designed and implemented a unit for five third-grade students that allowed them to understand Carbon Footprint (CF) in a public school in North Texas. The unit lasted seven weeks, where students identified the effects of distance traveled and packaging on the CF of certain consumable products.…
