Ying-Chih Chen; Jongchan Park; Jamie G. Rapkiewcz – American Biology Teacher, 2024
Productive struggle is a process in which students expend effort to grapple with perplexing problems and make sense of something that is not immediately apparent and beyond their current level of understanding and capacity. The experience encourages students to reflect on and restructure their existing knowledge toward a new understanding of…

Davies, Cristyn; Burns, Kellie – Sex Education: Sexuality, Society and Learning, 2023
Drawing on curriculum examples from Australia and Canada, we outline three key elements to support the development school-based HPV vaccination literacy for young people: (1) knowledge and understanding about HPV and HPV vaccination; (2) the scientific principles underpinning vaccination; and (3) the socio-political factors influencing HPV…

Sternberg, Robert J.; Ehsan, Hoda; Ghahremani, Mehdi – Roeper Review, 2022
In this article, we present a hierarchical model for teaching scientific thinking to gifted students. This article follows up on an article published 40 years ago in this journal. The problem now, as 40 years ago, is that gifted students often are taught science courses at a more intensive level, but without their truly learning how to think…

Annette Turney; Pauline Jones – Australian Journal of Language and Literacy, 2021
Digital media tasks are increasingly used in university settings to assess students' scientific knowledge. The use of such tasks has generated the need for principled analytical approaches to better understand how meaning-making operates in these artefacts. However, there has been a proliferation of approaches to multimodality in recent years and…

MacKellar, Jennifer J.; Constable, David J. C.; Kirchhoff, Mary M.; Hutchison, James E.; Beckman, Eric – Journal of Chemical Education, 2020
Although principles and practices of green and sustainable chemistry have been articulated for more than 20 years, they have yet to become systemically infused into the undergraduate chemistry curriculum. The American Chemical Society Green Chemistry Institute (ACS GCI) has convened stakeholders from across the chemistry education community to…

de Andrade, Vanessa; Freire, Sofia; Baptista, Mónica – Research in Science Education, 2019
This article describes a system of analysis aimed at characterizing students' scientific explanations. Science education literature and reform documents have been highlighting the importance of scientific explanations for students' conceptual understanding and for their understanding of the nature of scientific knowledge. Nevertheless, and despite…

Gregory S. Watson; Jolanta A. Watson – Journal of Chemical Education, 2023
With many universities now admitting students into their science programs with little or no prior knowledge of the relevant field, significant challenges arise in the way these fields are introduced. Challenges mount with various preconceived ideas regarding the levels of difficulty, thus necessitating introductory concepts be presented in…

Jing-Ping Liu; Pian Yan; Jinxi Lan; Rongying Yang; Wenqin Wang; Yulin Chen; Jingmin Wang; Yong Zhao; Jing Shen – Journal of Chemical Education, 2023
The Clemmensen reduction is a common example of a reaction demonstrating the deoxygenation of carbonyl groups, which is a topic that has been widely studied in the field of organic chemistry. The use of trimethylchlorosilane, as a substitute for concentrated hydrochloric acid, allows for the reduction of carbonyl groups. The Clemmensen reduction…

Ingram, Neil R. – School Science Review, 2020
Conrad Hal Waddington (1905--1975) was an English biologist who was especially interested in the big (metaphysical) questions of life. His thinking has become part of the foundation of modern systems biology. This article applies his thinking to middle-years school biology curricula (for ages 11-16), to see if their approach to epistemic questions…

Montejo Bernardo, Jose M.; Fernández González, Alfonso – Journal of Chemical Education, 2021
The periodic table is an essential topic in the teaching and learning of science at all education levels, as it contains information about the main physical and chemical properties of the different elements constituting the matter. However, becoming familiar with the facts behind the periodic table such as the element names and/or symbols, their…

Zhang, Kai – Journal of Chemical Education, 2020
In this article, we use a simple lattice model to illustrate the concepts of entropy, free energy, and thermodynamic equilibrium from a microscopic perspective. These physical concepts are based on elementary knowledge of discrete probability distribution and weighted average. Calculations about this model involve basic algebra and counting, which…

Beardsley, Paul; Csikari, Melissa; Ertzman, Ashley; Jeffus, Meghan – American Biology Teacher, 2022
Teachers are eager for professional development on teaching evolution, especially if it includes direct ties to relevant curricula and detailed lesson plans. Howard Hughes Medical Institute's BioInteractive Online Professional Learning: Evolution course was developed to provide educators with free, in-depth, multimedia resources that highlight…

Sengul, Ozden – School Science Review, 2020
This article describes the implementation of an activity with a Predict-Observe-Explain (POE) learning cycle to teach the concepts of velocity and acceleration to physics students aged 17-19. The study indicates how the instructor enacted the activity and provides sample student responses and group discussions. The description includes an example…

Keeley, Page – Science and Children, 2020
Since the release of "A Framework for K-12 Science Education" in 2012, there has been a significant shift toward the use of science and engineering practices that mirror the way scientists do their work (NRC 2012). The "Framework" states, "A focus on practices (in the plural) avoids the mistaken impression that there is…

Jiménez-Liso, Maria Rut; López-Banet, Luisa; Dillon, Justin – Science & Education, 2020
We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To support these instructional proposals, we identify four rationales for students to understand acid-base processes: daily life, socio-scientific, curriculum, and history of science. The extensive…
