There are conditions that lead professors to use different text formats in quantum physics courses. Studying these conditions is an important aspect to understand the dynamics of physics pedagogy, and philosophy of science can be used as an orientation to do so. A case study was conducted at a Brazilian initial physics teacher training program.…

While environmental problems are urgent in modern society, they are especially difficult to tackle because of their normative and politically controversial nature. Universities may choose different theoretical paradigms for the teaching of environmental problems. However, limited theoretical and/or practical analysis has been undertaken of the…

This 4-year longitudinal study identified the impact of a multifaceted mentoring and tutoring program on the retention and graduation rates of a diverse body of undergraduate college students enrolled in high-risk science courses. Findings revealed that the program was successful in increasing the retention and graduation rates of students who…

Despite continued efforts to address this issue, many students still exhibit misunderstandings regarding Newton's laws. These misconceptions include beliefs, such as every movement requires a force, that force is directly proportional to velocity, and that action-reaction forces can differ in magnitude. To mitigate these misunderstandings,…

Background/purpose: The students have difficulty understanding abstract concepts that are sometimes difficult to visualize in optics and physics, so learning innovations are needed to overcome these problems. Case-Based Learning (CBL) optical physics learning integrated with mobile microlearning offers an innovative approach to improving the…

Online learning in higher education has grown significantly over the past decade, with millions of students engaging with online learning tutorials and assessments. However, the effectiveness of online learning is less understood, particularly whether students achieve the same learning gains when taking online assessments at home versus in a…

Semimicro pressure filtration is carried out by pressurizing a suspension through pushing the piston of a gas-filled plastic syringe whose needle perforates the closure of a cylindrical filter funnel. Basic features as well as pros and cons of vacuum and pressure filtration are pointed out and compared to support rational choice between the two…

This is an easy and inexpensive laboratory experiment in which undergraduate students at the Bachelor's degree level in Chemistry can measure formation constants of complexes [Ni(en)[subscript n](OH[subscript 2])[subscript 6-2n]][superscript 2]+ (n = 1, 2 or 3; en = ethylenediamine) through an acid-base titration. The background information…

Elemental analysis is performed in a variety of ways in food and environmental sciences; thus, we have designed an activity in which students gain experience with research-level lab techniques in a real-world context through the quantification of key elements in breakfast cereals using microwave plasma optical emission spectroscopy (MP-OES). The…

A multistep synthesis of a novel arylidene 3­(2"H")-furanone has been designed and optimized for the second-year organic laboratory. The three-step sequence consists of a nucleophilic substitution, intramolecular cyclization, and acid-catalyzed aldol condensation, and can be carried out within two 3 h laboratory periods. The final…

Introductory anatomy and physiology courses are either taught as discipline-specific courses (human anatomy and human physiology) or integrated sequences [combined human anatomy and physiology (A&P I and A&P II)]. This variation suggests there is no agreed upon pedagogical standard for teaching introductory anatomy and physiology. We…

In an upper-division interdisciplinary laboratory experiment, students use Raman spectroscopy to highlight how the overall structure and conformational order of lipid bilayers can be influenced by their individual phospholipid composition. Students prepare a supported lipid bilayer, as a model cell membrane, by spreading liposomes made of various…

Graduate education in chemistry typically follows an apprenticeship model, primarily aimed at preparing students for academia; however, the inclusion of teaching within this apprenticeship is not always clear as faculty, students, and other stakeholders do not agree on the need for instructional training. Despite the variability in training, a…

In undergraduate classrooms, a majority of chemistry discoveries introduced are by white men and a small group of white women. There is greater online representation of chemists of diverse backgrounds, but the emphasis on diversity is mainly based on a monthly theme from Black History Month to Women's History Month. The "Diversity in…

The chemical enterprise is recognizing that inclusive and equitable environments are essential to its mission and advancement. As such, the education and training of chemists requires a reassessment of how academic programs integrate diversity, equity, and inclusion (DEI) as a core principle of educational quality. This article describes a 3-year…
