Fast, reliable, well-resolved latent fingerprints can be planted by applying a thin coating of a 50:50 mixture of hand lotion and food-grade protein powder. Fingerprints can be revealed with iodine fuming or ninhydrin staining. This low-cost alternative to commercial latent print pads can be used in a variety of classroom or public settings where…

Introducing chemical equilibrium concepts in undergraduate general chemistry promotes improved understanding of chemical reactions. We have developed an engaging laboratory experiment exploring the equilibrium of cobalt complexation in alcohols using UV-vis spectroscopy and successfully implemented in a large general chemistry class of 378…

A contemporary undergraduate laboratory experiment incorporating parallel microscale experimentation was developed for the well-defined palladium catalyzed Suzuki-Miyaura cross coupling of 4-fluorophenylboronic acid with both 4-chloro- and 4-bromoanisole using 11 diverse phosphine ligands and one ligandless control. This laboratory introduces…

This paper focused on describing students' result of learning through assessment of, for and as learning implementations. The subjects of research were 35 students on Chemistry Department, Mathematics and Science Faculty of Surabaya State University, Indonesia. The technique of data collecting was paper test 1, 2 and 3, that it was used to measure…

In the past thirty years, there have been many political changes in Croatia. These changes have had an impact on the education system, as well. The success of such educational changes depends on the teacher. The importance of teachers' knowledge and their beliefs about teaching and learning for their action in the classroom is well known. Beliefs…

The concept of delocalization (i.e., resonance) is fundamental concept in organic chemistry but essential learning outcomes (LOs) have not previously been proposed nor has there been an analysis of how resonance is taught, despite indications in the literature that students have many non-canonical ideas about the concepts. To address this deficit,…

Electrochemistry is omnipresent in our lives, but students often do not recognize that the electrochemistry they learn in general chemistry happens in the batteries on which we depend. Students also may not recognize that they have the power to make greener choices about batteries using their knowledge of chemistry. This 4 h general chemistry…

This study aimed to investigate changes in the understandings of the Nature of Science (NOS) of preservice chemistry teachers after participating in the explicit, reflective, and contextual NOS teaching. The sample of the study consisted of nine preservice chemistry teachers who attended scientific research methods course at the undergraduate…

Structure determination via NMR spectroscopy is a fundamental topic taught in many advanced level chemistry courses. Despite its importance as an analytical instrument, many students find the principle behind NMR-facilitated structure determination difficult to embrace. To this end, an artificial intelligence (AI) software package, namely,…

The dissertation is composed of two main parts. The first half describes efforts to study amyloid peptides using macrocyclic peptide model systems, and the potential deleterious effects of uronium peptide coupling agents on human health. The second half focuses on my experience in chemistry teaching and the chemical education research I conducted.…

In the undergraduate student laboratory teaching, one of the most common goals is developing improved conceptual understanding linking theory and practice. This study presents a phenomenographic analysis of pharmacy students' conceptions of the theory--practice relation in the laboratory. Through semi-structured interviews with pharmacy students…

Chemical bonding is an important topic which is difficult to teach well, especially for novices. This study set out to support preservice teacher educators by developing a framework for understanding and addressing the complexity of teaching chemical bonding. A model of pedagogical content knowledge (PCK) in science education that has been widely…

Objective: Community colleges have considerable potential to grow the number of individuals who complete STEM baccalaureate degrees and to broaden access to educational opportunities in STEM. However, efforts to tap this potential have been hampered by nagging questions about whether community colleges prepare students adequately for advanced STEM…

The goal of this study was to assess students' level of conceptual understanding of chemical kinetics and equilibrium using topic-specific pedagogical content knowledge (TSPCK)-based instruction in chemistry grade 11 students. The research was a mixed approach that involved 159 grade 11 chemistry class students from Addis Ababa administrative…

The relevance of the research in this article is conditioned upon the problems of introducing environment-oriented education in the field of chemical discipline for the development of an important component of the information part of this science among students, based on its application in the framework of restoration and conservation of ecology.…
