Globalization, in the case of science education, leads not only to an increase in homogeneity but also to an increase in cultural encounters. In this study, researchers from 2 distinct cultures, South Africa and Finland, used a qualitative approach to probe student teachers' perspectives on chemistry education. Participants were 1st-year chemistry…

Although Advanced Placement (AP) courses are intended to promote rigorous, college-level instruction for high school students, AP tests have been criticized for privileging breadth over depth. In response to both this criticism and to the 2002 National Research Council (NRC) report on STEM education, AP Biology, Chemistry, and Physics curricula…

United Nations declared 2011 to be the International Year of Chemistry. The Swedish Chemical Society chose twelve themes, one for each month, to highlight the connection of chemistry with everyday life. Examples of themes were fashion, climate change, love, sports, communication, health issues, and food. From the themes various context-based…

Dominant educational approaches in chemistry focus on the learning of somewhat isolated concepts and ideas about chemical substances and reactions. Reform efforts often seek to engage students in the generation of knowledge through the investigation of chemical phenomena, with emphasis on the development and application of models to build causal…

Finding the best ways to introduce quantum physics to undergraduate students in all scientific areas, in particular for chemistry students, is a pressing, but hardly a simple task. In this paper, we discuss the relevance of taking into account lessons from the history of the discipline and the ongoing controversy over its interpretations and…

Although observational protocols have been developed that assess different aspects of science teaching, none of the protocols existing in the literature address the principles of effective chemistry instruction guided by Johnstone's triangle of macroscopic, symbolic, and particulate representations of matter (Johnstone, 1991). We developed our own…

In this paper, we define flip teaching as a curricular platform that uses various strategies, tools, and pedagogies to engage learners in self-directed learning outside the classroom before face-to-face meetings with teachers in the classroom. With this understanding, we adopted flip teaching in the design and enactment of one Year 1 and one Year…

Learning communities (LCs) offer high-impact practices of active learning and practical application, but such practices demand devoted class time and room for reflection. Core science courses that serve as prerequisites for more advanced courses have specific and fixed content that offers no space in which to incorporate the ideals of LCs. Wagner…

Most of countries are trying to develop their education systems. Since the new generations are their future, they want to give a good education. So they have the biggest objective of their educational system to educate modern, productive responsible, qualified and educated people who also take side of solutions instead of problems. The educated…

The precise measurement of conductivity of a semiconductor film such as polypyrrole (Ppy) should be carried out by the four-point probe method; however, this is difficult for classroom application. This article describes the development of a new, convenient, handmade conductivity device from inexpensive materials that can measure the conductivity…

This laboratory experiment gives upper-division organic or biochemistry undergraduate students a comprehensive look at the synthesis, chemical characterization, self-assembly, and secondary structure determination of small, N-acylated peptides inspired by the protein structure of silkworm silk. All experiments can be completed in one 4 h lab…

Undergraduate laboratories generally teach an understanding of chemical reactivity using bulk or semimicroscale experiments with product isolation and subsequent chemical and spectroscopic analysis. In this study students were exposed to mass spectrometry as a means of chemical synthesis as well as analysis. The ionization method used, paper…

A modified technique for demonstrating the magnitude of Avogadro's number using a new Raspberry Pi computer and the Python language is described. The technique also provides students the opportunity to review dimensional analysis.

An undergraduate organic chemistry laboratory experiment has been developed that features a discovery-based microscale Fischer esterification utilizing a microwave reactor. Students individually synthesize a unique ester from known sets of alcohols and carboxylic acids. Each student identifies the best reaction conditions given their particular…

Five reactions were rate-accelerated relative to the standard reflux workup in both multi-mode and mono-mode microwave ovens, and the results were compared to determine whether the sequential processing of a mono-mode unit could provide for better lab logistics and pedagogy. Conditions were optimized so that yields matched in both types of…
