Jai S. Polepalli; Helen Gooch; Pankaj Sah – npj Science of Learning, 2020
The basolateral amygdala (BLA) is a temporal lobe structure that contributes to a host of behaviors. In particular, it is a central player in learning about aversive events and thus assigning emotional valence to sensory events. It is a cortical-like structure and contains glutamatergic pyramidal neurons and GABAergic interneurons. It is divided…

Wallen, Scott L.; Dhau, Jaspreet; Green, Robert; Wemple, Laura B.; Kelly, Troy, Jr.; Collins, Brent – Journal of Chemical Education, 2020
Over the past decade the Accreditation Board for Engineering and Technology, Inc. (ABET) has changed the general chemistry requirements to include a single introductory course for most engineering majors. There is a focus on outcomes that equip students with the ability to pass the Fundamentals of Engineering (FE) Exam and to work in…

Ramesh, Vinay Bapu; Selvam, Athavan Alias Anand; Kulkarni, Surabhi; Manganahalli, Anusha Dattatreya; Bettadapur, Kiran R. – Journal of Chemical Education, 2020
High school students find reaction stoichiometry and the concept of the mole hard to comprehend. Teachers are well aware of the importance of teaching the mole concept and also the difficulty associated with it. In an attempt to improve the understanding of the mole concept with reduced difficulty, an atomic model kit that provides a hands-on…

Stott, Angela Elisabeth – Chemistry Education Research and Practice, 2021
Stoichiometry calculation competence tends to be particularly poor in the developing world, even among teachers. Various methods, including the unit factor method, have the potential to be effective in developing such competence. To evaluate the likelihood of such a generic proportion method, which downplays traditional formula usage, succeeding…

Pablo Serna-Gallén; Maria Fortuño-Morte; Héctor Beltrán-Mir; Eloísa Cordoncillo – Journal of Chemical Education, 2022
This article presents and discusses the results of an educational innovation that seeks to introduce the world of molecular gastronomy in chemistry lessons as a means to review stoichiometry and offer an alternative way to learn. In the literature to date, there is no evidence of haute cuisine having been employed to contextualize stoichiometry…

Michmerhuizen, Anna; Rose, Karine; Annankra, Wentiirim; Vander Griend, Douglas A. – Journal of Chemical Education, 2017
Making optimal pedagogical and predictive use of the radius ratio rule to distinguish between solid state structures that feature tetrahedral, octahedral and cubic holes requires several updated insights. A comparative analysis of the Born-Landé equation for lattice energy is developed to show that the rock salt structure is a suitable choice for…

Boesdorfer, Sarah B.; Arias, Anna Maria; Mull, Bayleigh; Lieberum, Kyle – School Science and Mathematics, 2020
Curriculum materials can play a major role in shaping teachers' thinking about instruction and content as well as serve as a support for teachers' learning. With the inclusion of engineering in NGSS, many teachers may be turning to existing curriculum materials to help them infuse engineering into their science classroom, especially when they do…

Ralph, Vanessa R.; Lewis, Scott E. – Chemistry Education Research and Practice, 2019
Students who score within the bottom quartile on cognitive measures of math aptitude have been identified as at-risk for low performance in chemistry courses, with less attention as to "why" such differential performance persists. At-risk students struggle most differentially on assessment items related to the mole concept and…

Alvarez-Montan~o, Victor E.; Farías, Mario H.; Brown, Francisco; Mun~oz-Palma, Iliana C.; Cubillas, Fernando; Castillon-Barraza, Felipe F. – Journal of Chemical Education, 2017
A good understanding of ternary phase diagrams is required to advance and/or to reproduce experimental research in solid-state and materials chemistry. The aim of this paper is to describe the solutions to problems that appear when studying or determining ternary phase diagrams. A brief description of the principal features shown in phase diagrams…

Gulacar, Ozcan; Tan, Alexandra; Cox, Charles T., Jr.; Bloomquist, Jennifer; Jimmy, Okechukwu; Cao, Nguyen – Education Sciences, 2019
To gauge the variability in expert problem-solving strategies for stoichiometry problems, a set of experts in different career tracks were studied with the cohort including 17 graduate students in chemistry, three college chemistry instructors, and seven college graduates working in the industry. The goal of the study was to determine whether…

Li, Manyu; Wang, Yu; Stone, Heather N.; Turki, Nadia – Education Sciences, 2021
The purpose of this randomized experimental study is to apply two socio-cognitive models to understand possible ways to improve students' learning outcomes in an online introductory chemistry learning environment. Specifically, the social presence theory suggested that students' sense of relatedness and learning motivation can be increased by a…

Segedinac, M. T.; Horvat, S.; Rodic, D. D.; Roncevic, T. N.; Savic, G. – Chemistry Education Research and Practice, 2018
This paper proposes a novel application of knowledge space theory for identifying discrepancies between the knowledge structure that experts expect students to have and the real knowledge structure that students demonstrate on tests. The proposed approach combines two methods of constructing knowledge spaces. The expected knowledge space is…

Ralph, Vanessa Rosa; States, Nicole E.; Corrales, Adriana; Nguyen, Yvonne; Atkinson, Molly B. – Chemistry Education Research and Practice, 2022
Emphasizing stoichiometry appears to be a norm of introductory chemistry courses. In this longitudinal and mixed-methods study, we examined how the emphasis on stoichiometry in assessments of introductory chemistry impacted educational equity and student learning. Using quantitative methods, we identified mole and stoichiometric conversions as two…

Miheso, Josephat M.; Mavhunga, Elizabeth – Chemistry Education Research and Practice, 2020
What evidence counts as teacher quality is a debate of continued interest to the teacher education community. Many education scholars have argued for the importance of retention of knowledge as an indicator of the quality of education acquired. This study explored the retention of the quality of planned Topic Specific Pedagogical Content Knowledge…

Chitiyo, George; Potter, Darek W.; Rezsnyak, Chad E. – Journal of Chemical Education, 2018
The "Atoms-First" approach has received considerable attention in the chemical education community over the past few years as an alternative to the standard reaction-based two-semester General Chemistry curriculum. The Atoms-First model emphasizes the electronic structure of the atom as a means to explain and rationalize chemical…
