Watla-iad, Kanchana; Kradtap Hartwell, Supaporn – Journal of Chemical Education, 2022
The ability to collaborate with culturally diverse groups is essential, not only to further scientific knowledge but also to solve complex global problems. However, not all students have opportunities to develop intercultural competencies through study abroad programs, due to various issues such as cost, rigid curriculum, and unrelated field of…

Aftenieva, Olha; Schletz, Daniel; Meyer, Antonia; Ku¨hne, Tino; Schmalzriedt, Sierk; Niethammer, Manuela; Ko¨nig, Tobias A. F. – Journal of Chemical Education, 2021
In contrast to a macroscopic solid, the color and spectroscopic properties of gold nanoparticles change with size. Here, we propose a teaching platform for high school students (hereafter defined as students, attending secondary school in Europe, preparatory high schools in the US, or any educational institution of a comparable level) that…

A green chemistry experiment is presented for teaching an undergraduate quantitative analysis/analytical chemistry laboratory class through the use of black tea leaf extract for the determination of iron in supplement tablets. Dried tea leaf is a safe, low cost, and widely available source of natural extract that can be used in place of more toxic…

Identifying Systems Thinking Components in the School Science Curricular Standards of Four Countries
Chiu, Mei-Hung; Mamlok-Naman, Rachel; Apotheker, Jan – Journal of Chemical Education, 2019
Chemistry plays an important role in developing scientific theories to describe, explain, and predict the physical world and to produce useful products for improving quality of life throughout history. To arouse student awareness of the value and importance of learning chemistry and becoming chemistry literate, we propose an application of systems…

Leak, Anne E.; Sciaky, Elizabeth; Lenaburg, Lubella; Bianchini, Julie A.; Scott, Susannah – Journal of Chemical Education, 2018
This study explores how graduate students learn to participate in collaborative international science research. As part of an NSF-funded program, 21 graduate students participated in extended research visits to China, completing surveys before and after traveling, and participating in semistructured interviews upon returning to the U.S. These…

Wan, Yanlan; Bi, Hualin – Journal of Chemical Education, 2016
Chemistry core ideas play an important role in students' chemistry learning. On the basis of the representations of chemistry core ideas about "substances" and "processes" in the Chinese Chemistry Curriculum Standards (CCCS) and the U.S. Next Generation Science Standards (NGSS), we conduct a critical comparison of chemistry…

Vrabec, Michal; Prokša, Miroslav – Journal of Chemical Education, 2016
In this article we present the results of a study in which we tested the use of the experimental inventory BRI (Bonding Representations Inventory), developed by Cynthia J. Luxford and Stacey Lowery Bretz. The aim of our study was to test the usability of the experimental instrument in the Slovak educational system and to identify concrete…

Elmgren, Maja; Ho, Felix; Åkesson, Eva; Schmid, Siegbert; Towns, Marcy – Journal of Chemical Education, 2015
Chemistry education focused on learning outcomes is increasingly practiced, providing new opportunities for international comparisons. The interest in intended learning outcomes and constructive alignment has grown in many parts of the world due to both research in higher education and political decisions. In an International Union of Pure and…

Rayner-Canham, Geoff; Rayner-Canham, Marelene – Journal of Chemical Education, 2015
Though guided-inquiry learning, discovery learning, student-centered learning, and problem-based learning are commonly believed to be recent new approaches to the teaching of chemistry, in fact, the concept dates back to the late 19th century. Here, we will show that it was the British chemist, Henry Armstrong, who pioneered this technique,…

Wei, Silin; Liu, Xiufeng; Wang, Zuhao; Wang, Xingqiao – Journal of Chemical Education, 2012
Research suggests that difficulty in making connections among three levels of chemical representations--macroscopic, submicroscopic, and symbolic--is a primary reason for student alternative conceptions of chemistry concepts, and computer modeling is promising to help students make the connections. However, no computer modeling-based assessment…

Loshbaugh, Heidi G.; Laursen, Sandra L.; Thiry, Heather – Journal of Chemical Education, 2011
Calls for reform in graduate education have emerged from professional societies, educational research, and foundations, with particular concern for how graduate students are prepared for their future professional environments. This qualitative research study explores current issues in Ph.D. chemistry education, including how U.S. chemistry…

Kuntzleman, Thomas S.; Baldwin, Bruce W. – Journal of Chemical Education, 2011
We believe that students should have opportunities--early and often--to learn about science and math activities in fun and recreational ways. As a result, we try to provide many science enrichment activities to the surrounding community. In doing so, we hope to inspire young students to become future scientists and mathematicians. Here we describe…

Sharma, Vinita; McKone, Harold T.; Markow, Peter G. – Journal of Chemical Education, 2011
This article presents a brief history of the artificial coloration of foods, a discussion of the worldwide use of synthetic food dyes, and methods for separating and identifying 14 dyes in common use globally. The United States Food and Drug Administration presently has certified seven synthetic dyes for use in foods. An additional seven synthetic…

Niaz, Mansoor; Cardellini, Liberato – Journal of Chemical Education, 2011
Bohr's model of the atom is considered to be important by general chemistry textbooks. A shortcoming of this model was that it could not explain the spectra of atoms containing more than one electron. To increase the explanatory power of the model, Sommerfeld hypothesized the existence of elliptical orbits. This study aims to elaborate a framework…

Martin, Christopher B.; Schmidt, Monica; Soniat, Michael – Journal of Chemical Education, 2011
A survey was conducted of four-year institutions that teach undergraduate organic chemistry laboratories in the United States. The data include results from over 130 schools, describes the current practices at these institutions, and discusses the statistical results such as the scale of the laboratories performed, the chemical techniques applied,…
