We have revamped a classic analytical chemistry laboratory experiment, "Determination of an Unknown Acid", to provide students an opportunity to learn about new advances in the material sciences and their applications in analytical chemistry in an effort to reinforce the key concepts of chemical analysis. Specifically, students were…

In modern Western education, the visual arts have come to hold a problematic position in the school curriculum. Art is often classified by school leaders, students, parents and even teachers as different from other subjects; sometimes viewed as almost magical, enabling students to explore and develop an innate creativity; sometimes simply…

In Physical Education Teacher Education programs, we argue that a focus on fewer models to be taught and learned would provide time for higher competence to be attained by preservice teachers in a curriculum limited in terms of contact hours. During their teacher training, preservice teachers should be given ample opportunities to practice the…

Biochemistry primarily focuses on the non-metal chemical elements carbon, oxygen, nitrogen, hydrogen, sulfur, and phosphorus in the four groups of building blocks (sugars, lipids, amino acids, and nucleotides) and the corresponding macromolecules. However, at least 10 essential chemical elements of life are metals. This article discusses the…

The use of mass spectrometry (MS) is becoming widespread and rather routine in all levels of industry, government, and academia. Coupled with chromatographic methods, this powerful instrumental technique can be used to elucidate the composition of a complex sample and definitively identify constituents while offering the benefits of high-precision…

We present a simple undergraduate level experiment dealing with the preparation and characterization of a colloidal Langmuir-Blodgett (LB) film. The experiment is designed to invoke an interdisciplinary understanding of colloid chemistry and surface science. It will allow the students to develop the concepts of wettability, hydrophobicity, and…

Purpurogallin (PPG), an orange-red crystalline compound from nutgalls and oak bark, is an exemplar of numerous, ubiquitous natural colorants, biosynthesized through oxidative dimerization-decarboxylation of phenolic compounds. It possesses antioxidant, anticancer, and anti-inflammatory effects. Herein, a robust method is presented to allow…

Computers and computer algorithms have contributed to important scientific advances by allowing scientists and engineers to create and use sophisticated models to explain and predict phenomena. Yet, of the eight "Next Generation Science Standards" ("NGSS") science and engineering practices, computational thinking may be the…

The paper aims to develop training for teachers to perceive non-verbal cues in online classes. The training is prepared based on a mindmap suggesting alternative tools available in the online platforms to gauge non-verbal cues in online lectures. The findings indicate that after the training, teachers could perceive students' non-verbal cues…

The Unlearning Cycle offers a way to help educators identify some of the underlying assumptions and beliefs we bring to our pedagogical design. In a field so focused on learning, it is actually unlearning we need to focus on. This chapter shares research and strategies to trade up for new ways of teaching and designing for inclusive, rigorous…

Physical education is an important venue to develop children's motor competencies and healthy lifestyles. It is concerning that participation rates in secondary physical education classes have been declining in recent years. The decline is often associated with a decreased level of motivation. While many physical educators are struggling with…

In this article, the author opines that bell hooks' deepest, most complex contribution to antiracist teaching is her 2001 book "All About Love: New Visions" rather than titles such as "Teaching to Transgress: Education as the Practice of Freedom" (1994) or "Teaching Community: A Pedagogy of Hope" (2003). The author…

Critical appraisal of evidence is performed to assess its validity, trustworthiness and usefulness in evidence-based practice. There currently exists a large number and variety of critical appraisal tools (also named risk of bias tools and quality assessment instruments), which makes it challenging to identify and choose an appropriate tool to…

In this article, the author shares her research, as well as the work of other scholars, on social studies education narratives that portray individuals as heroes or villains and the effect these portrayals may have on students. These narratives not only stifle students' feelings of civic agency, but they minimize the role of community in creating…

Approaching assessment from an end-to-end perspective helps with appropriate assessment selection, design, and practice. Thinking in terms of end-to-end reminds teachers to keep in sight the aspirations (or ends) associated with any assessment activity. It also helps teachers to consider how to integrate assessment activities and capabilities into…
