An organic chemistry experiment is described that is based on recent research to elucidate a novel cation-pi interaction between tetraalkammonium cations and propargyl hydrazines. This nonbonded interaction is a key component of the mechanism of ammonium-catalyzed intramolecular cycloaddition of nitrogen to the terminal carbon of a C-C triple bond…

A laboratory experiment is described in which students synthesize silver nanospheres and transform them into other anisotropic morphologies (decahedral and disks) through a photochemical process. The photochemical transformation was followed by visible spectroscopy, and the resulting morphologies were analyzed using scanning electron microscopy.…

Although mainly used by the hobby or "maker" crowd, the Arduino microcontroller has made its way into all levels of education, including physics labs. Perhaps the most compelling aspect of the Arduino in this regard is the ease with which it can be interfaced and acquire data from a sensor, using any one of its many analog inputs, SPI or…

This research was conducted to analyze the teaching factory model in vocational high school ("sekolah menengah kejuruan"/SMK) in Central Java Province, Indonesia according to the teaching factory's success factors. This research used meta-ethnography for qualitative methods and Delphi technique, Research and Development, and social…

This article investigates the perspectives of international students in the United States who use writing centers to support their identities and to meet their writing needs and goals. Using survey and focus group data to look closely at how students use one writing center's online Profile and more broadly at the accessibility and responsiveness…

Technology and validation methods for producing biodiesel have been updated and have kept advancing. Creative raw materials used in producing environmentally friendly biodiesels have also attracted interest from scientists. Thus, learning and teaching methods on biodiesel production at the high school level need to be up to date. However, there…

Scientific competencies, as defined in the German competency framework, describe the ability to think independently and act scientifically which is a central component of medical education. This report describes integration of scientific competencies into anatomical teaching. Based on findings seen in two consecutive years of dissection courses,…

Animal dissection is practiced to varying degrees around the world and is particularly prevalent in North America throughout all levels of education. However, a growing number of studies suggest that nonanimal teaching methods (NAMs) (e.g., virtual anatomy tools and three-dimensional models) are better for achieving learning goals compared to…

In this article, we describe a multi-year writing intervention in a highenrollment professional pharmacy course, implemented by a multidisciplinary team of pharmacy and writing instructors. Built around one capstone writing assignment, the "drug information question" paper, the intervention was designed to specifically improve students'…

Laboratory courses are an important part of the undergraduate physics curriculum. During physics labs, students can engage in authentic, hands-on experimental practices, which can prepare them for graduate school, research laboratories, and jobs in industry. Because of the COVID-19 pandemic in Spring 2020, colleges and universities across the…

In the U.S. school systems, Native American students receive harsher and more frequent school discipline than White counterparts. Exclusionary discipline may result in adverse academic, social, and life outcomes. There is an urgent need for creating an inclusive, equity-oriented learning environment where Native American students' identities,…

Measurement of multiple competencies of students is getting more emphasis in undergraduate education validating the need for work-ready graduates. We developed the objective structured laboratory examination (OSLE) to measure the practical competencies of final year biomedical science students. This paper analyses the impact of OSLE on students'…

Broadening access to science, technology, engineering, and mathematics (STEM) professions through the provision of early-career research experiences for a wide range of demographic groups is important for the diversification of the STEM workforce. The size and diversity of the community college system make it a prime educational site for achieving…

Biology laboratory instructors play a key role in creating an optimal environment where college students try hard and enjoy their classroom experiences. This study used achievement goal perspective theory to examine the influence of instructor behaviors on science, technology, engineering, and mathematics (STEM) students' perceptions of the…

The affordances of technology-based assessments, like the objectively structured practical examination, have become an integral part of gross anatomy courses. The Department of Anatomy Faculty of Medicine at the University of Warmia and Mazury developed and introduced an application for tablet devices which has been implemented in student…
