Colloidal stability is one of the most important criteria in the application strategy of colloidal nanoparticles in the continuous phase. The branches include ecology, involving coagulation as a purification method; medicine as nanocarriers; biology as blood coagulation, etc. A chemist versed in these concepts is a high-performing chemist in…

The use of a multicompartment electrochemical cell for the potentiometric determination of solubility product constants of aqueous I[superscript -], Br[superscript -], SCN[superscript -], and Cl[superscript -] salts of silver is presented. An electrochemical cell presented in this study contained multiple half-cells made of disposable drinking…

The implementation of a laboratory exercise in an undergraduate chemistry course, where students perform a comparison of three different synthetic methods toward [Cu(Cl)(IPr)]-complexes (IPr = N,N'-bis(2,6-diisopropylphenyl)imidazol-2-ylidene), is described. The students are introduced to the continuous improvement of reactions in terms of green…

An undergraduate music class was examined that incorporated the creation of students' individual original raps. Research was conducted to understand the value of studying rap and its impact upon students' education. This instrumental case study utilised students' individual raps as an art-based research component to address three research…

Undergraduate psychology education has also faced the fact that two-thirds of its graduates immediately apply for jobs in the private or public sector rather than pursuing master's studies (Norcross et al.,2016). In this context, faculty members of psychology departments deliberated at an American Psychological Association (APA) conference in2008…

The purpose of this study was to uncover and describe the multiple, divergent student viewpoints about an undergraduate mechanical engineering program at a public university in the US Midwest and their persistence in that program. This study uses Q methodology which mixes qualitative and quantitative research aspects to reveal and describe the…

Through galleries of graphs and short filmstrips, this paper aims to sharpen students' eyes for visually recognizing continuous functions. It seeks to develop intuition for what visual features of a graph continuity does and does not allow for. We have found that even students who can work correctly with rigorous definitions may not be able to…

Background: Textbooks shape the content and structure of most introductory psychology courses. It is important to compare the content of textbooks to assist educators in making the best textbook choice. Objective: The purpose of this study was to conduct an analysis of five commonly used introductory psychology textbooks and examine the extent of…

The 2011 "Vision & Change" report outlined several recommendations for transforming undergraduate biology education, sparking multiple pedagogical reform efforts. Among these was the Promoting Active Learning and Mentoring (PALM) network, an NSF-funded program that provided mentorship and training to instructors on implementing…

This project seeks to fill gaps in the knowledge about the long-term benefits of undergraduate participation in community-engaged service learning (CESL). A mixed-methods research protocol delivered to graduates of an R1 public university three years after the completion of a CESL senior capstone course observed significant divergences in…

The evidence for a reproducibility crisis in the sciences is overwhelming. Nevertheless, this crisis has not received sufficient attention in kinesiology. This must be remedied for kinesiology research is as vulnerable to the problems of the reproducibility crisis as any other discipline. The causes of this crisis include human, statistical and…

This paper reflects on teaching sport in political geography undergraduate courses in the United States, through which I simultaneously aim to de-essentialize geopolitics and de-essentialize sport. I integrate sport examples in diverse courses on political geography and teach a dedicated "Geopolitics of Sport" course. By framing my…

We propose an adaptive methodology for the curricular redesign based on the performance indicators of the student progression observed after a follow-up period. The feasibility of adopting the same approach should be thoroughly studied to assess its compatibility with institutions and countries that employ an academic credit system based on…

We present a concrete situation where there is a difference between the theoretical security of a cipher and its limitations when implemented in practice. Specifically, when entering a PIN, smudges on the keypad substantially reduce its security. We show how the number of possible keys in the presence of the "smudge attack" can be…

Machine learning (ML) is extensively applied in chemistry, particularly in vibrational spectroscopy. However, few teaching examples effectively demonstrate the capabilities of ML in classifying polymeric materials, exhibiting subtle spectral differences that elude visual discrimination. This study presents a teaching example specifically tailored…
