Correct responding to questions regarding events that have occurred in the past are important for conversations and safety. Limited research has demonstrated techniques for teaching this skill to children who do not successfully tact past events. The current study demonstrates a probe-fading method for teaching children to correctly tact stimuli…

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…

Undergraduate research is an important component of a B.Tech. Biotechnology program. In the present study, a customizable approach designed with open-source bioinformatics tools and databases was introduced to predict siRNAs for ZIKV therapeutics. With minimal prior exposure to bioinformatics, this workflow can be executed with detailed steps as…

Evidence based medicine (EBM) has been synonymous to delivery of quality care for almost thirty years. Since the movement's inception, the assumption has been that decisions based on high quality evidence would translate to better care for patients. Despite EBM's many attractive features and the substantive attention it has received in the…

In this experiment we have first determined the focal length of an equiconvex lens. We have observed that a real image can be formed by the lens on the same side of the source if the source is sufficiently strong. This is due to the reflection from the concave surface of the lens. We have measured these image distances for different object…

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 refractive index (RI) is probably the single most important parameter in optical systems. Chromatic dispersion, on the other hand, indicates how the RI depends on the wavelength and is central in, e.g., optical communication systems. Chromatic dispersion also plays an important role when teaching optics due to the captivating natural…

The paper is based on the hypothesis and the assumption that teachers' beliefs and perspectives on teaching have a significant impact on their behaviour in the classroom, as well as that they guide and direct reflexivity in teaching practice. In that manner, the teachers' beliefs and their reflective practice have become the necessary and integral…

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…

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…

The wave nature of light has been widely demonstrated in a double-slit experiment, which has played a special role in physics teaching. When monochromatic light passes through the double-slit sheet, the diffraction and interference fringes can be observed in the far-field regime. The interference of light causes the beams passing through the two…
