Bailey, James A. – Journal of Chemical Education, 2011
Although there are numerous inorganic model systems that are readily presented as undergraduate laboratory experiments in bioinorganic chemistry, there are few examples that explore the inorganic chemistry of actual biological molecules. We present a laboratory experiment using the oxygen-binding protein myoglobin that can be easily incorporated…

Spinelli Barria, Michele; Morales, Cecilia; Merino, Cristian; Quiroz, Waldo – Chemistry Education Research and Practice, 2016
In this work, we developed an ontological tool, based on the scientific realism of Mario Bunge, for the analysis of the presentation of natural processes in science textbooks. This tool was applied to analyze the presentation of the concept of osmosis in 16 chemistry and biology books at different educational levels. The results showed that more…

Msimanga, Audrey; Lelliott, Anthony – International Journal of Science Education, 2014
This paper discusses the nature of learner engagement with science content during small group discussions in which learners use their home languages. We observed that learners reverted to their home languages in small group discussions, yet very little is known about the dynamics of learner engagement when they use their home languages in…

Herga, Nataša Rizman; Grmek, Milena Ivanuš; Dinevski, Dejan – Turkish Online Journal of Educational Technology - TOJET, 2014
Using a variety of visualization tools for teaching and learning science and chemistry is necessary because pupils better understand chemical phenomena and formulate appropriate mental models. The purpose of the presented study was to determine the importance of a virtual laboratory as a visualization element when addressing chemical contents…

Cloonan, Carrie A.; Nichol, Carolyn A.; Hutchinson, John S. – Journal of Chemical Education, 2011
Chemical reaction kinetics and equilibrium are essential core concepts of chemistry but are challenging topics for many students, both at the high school and undergraduate university level. Visualization at the molecular level is valuable to aid understanding of reaction kinetics and equilibrium. This activity provides a discovery-based method to…

Kumi, Bryna C.; Olimpo, Jeffrey T.; Bartlett, Felicia; Dixon, Bonnie L. – Chemistry Education Research and Practice, 2013
The use of two-dimensional (2D) representations to communicate and reason about micromolecular phenomena is common practice in chemistry. While experts are adept at using such representations, research suggests that novices often exhibit great difficulty in understanding, manipulating, and translating between various representational forms. When…

Cloonan, Carrie A.; Andrew, Julie A.; Nichol, Carolyn A.; Hutchinson, John S. – Journal of Chemical Education, 2011
This article describes an activity that can be used as an inquiry-based laboratory or demonstration for either high school or undergraduate chemistry students to provide a basis for understanding both vapor pressure and the concept of dynamic phase equilibrium. The activity includes a simple setup to create a closed system of only water liquid and…

Niaz, Mansoor; Kwon, Sangwoon; Kim, Nahyun; Lee, Gyoungho – Physics Education, 2013
Research in science education has recognized the importance of teaching atomic structure within a history and philosophy of science perspective. The objective of this study is to evaluate general physics textbooks published in Korea based on the eight criteria developed in previous research. The result of this study shows that Korean general…

Sweet, Chelsea; Akinfenwa, Oyewumi; Foley, Jonathan J., IV – Journal of Chemical Education, 2018
We present an interactive discovery-based approach to studying the properties of real gases using simple, yet realistic, molecular dynamics software. Use of this approach opens up a variety of opportunities for students to interact with the behaviors and underlying theories of real gases. Students can visualize gas behavior under a variety of…

Simonson, Shawn R., Ed. – Stylus Publishing LLC, 2019
Process Oriented Guided Inquiry Learning (POGIL) is a pedagogy that is based on research on how people learn and has been shown to lead to better student outcomes in many contexts and in a variety of academic disciplines. Beyond facilitating students' mastery of a discipline, it promotes vital educational outcomes such as communication skills and…

Evans, Karen L.; Leinhardt, Gaea – Journal of Science Education and Technology, 2008
Many students now are receiving instruction in online environments created by universities, museums, corporations, and even students. What features of a given online course contribute to its effectiveness? This paper addresses that query by proposing and applying an analytic framework to five online introductory chemistry courses. Introductory…

Cranwell, Philippa B.; Page, Elizabeth M. – New Directions in the Teaching of Physical Sciences, 2020
The use of a group-based approach to project working has been shown to provide significant advantage to students in terms of project outcomes, motivation and engagement. The Department of Chemistry at the University of Reading has recently explored the use of group projects for final year practical work. In this model, students are presented with…

Scharon, Aracelis Janelle – ProQuest LLC, 2013
The Next Generation Science Standards (NRC, 2013) positions teachers as responsible for necessary decision making about how their intended science lesson plan content supports continuous student science learning. Teachers interact with their instructional lesson plans in dynamic and constructive ways. Adapting lesson plans is complex. This process…

Kaliakin, Danil S.; Zaari, Ryan R.; Varganov, Sergey A. – Journal of Chemical Education, 2015
Teaching fundamental physical chemistry concepts such as the potential energy surface, transition state, and reaction path is a challenging task. The traditionally used oversimplified 2D representation of potential and free energy surfaces makes this task even more difficult and often confuses students. We show how this 2D representation can be…

Klawiter, Mark F. – Journal of Chemical Education, 2015
Chemistry taught in high schools typically has group interaction components designed to provide opportunities for groups of two or more students to collaborate. Such opportunities, however, can lead to diminished learning among some students, as domination, group dissonance, and/or non-participation among group members can derail the collaborative…
