Stereotypical imagery of scientists is detrimental to effective and inclusive science education. Many elementary pre-services teachers often hold onto these images, creating an unconscious bias limiting their effectiveness to both teach science content and discourage some groups from entering the scientific field. Proactive and targeted…

In 1900, three botanists claimed they had found regularities in inheritance, which soon would be known as Mendel's Laws, without knowing the work of Gregor Mendel or of each other. Their claims of independent (re)discovery have been thoroughly studied during the past decades, with various outcomes. The case is still of interest today as it offers…

The past two decades have seen a rise in citizen science projects and tools available for formal and informal learning; however, research has indicated there is a dearth of professional development for educators regarding understanding, adapting, and applying these resources in their learning environments. To address this gap, we created the…

In our taught chemistry curricula, the majority of individuals who are used to illustrate historical aspects of chemistry topics are white, western chemists. Decolonizing the undergraduate chemistry curricula is increasingly recognized as an important step toward developing a more inclusive higher-education environment for students from…

The biographical stories of scientists and engineers, particularly those from historically excluded groups, have been integrated into the curriculum for a materials science course. The goal is to help students connect and relate to the scientific content, while opening the door to conversations about social justice in the virtual classroom. We…

Student experiences learning chemistry have been well studied in chemistry courses but less so in biology courses. Chemistry concepts are foundational to introductory biology courses, and student experiences learning chemistry concepts may impact their overall course experiences and subsequent student outcomes. In this study, we asked…

Enabling students to learn about science is essential for science education. Students are expected to not only gain scientific knowledge but also need to develop a deep understanding of science. One approach to equipping students with a sense of science is to present science as a living collective human enterprise. As essential educational…

Although Ohm's law contains various possibilities in teaching and learning scientific inquiry, it is rare for students to experience an authentic inquiry. Thus, we designed an open-ended in-depth inquiry about Ohm's law and made students conduct it. To do this, we developed a laboratory activity for students following a standard method of Ohm's…

"American Biology Teacher" has published over seven dozen articles relevant to the history of biology in biology teaching. They are cataloged here and indexed by topic. As reflected in this archive, teachers adopt a historical approach for many pragmatic motivations: (1) to engage students, by contextualizing science culturally; (2) to…

In the museum wing of the Greenslade house is a clock with a two-second pendulum about one meter long. This ticks once per second, and every time it passes through dead center it completes an electrical circuit. When I came to Kenyon in 1964, this system was used to send signals to a series of telegraph relays, which ticked once per second.…

As science educators, we have an important opportunity to influence perceptions of who does science, and we can work to empower students to make our disciplines more accessible to people of all backgrounds. This goal was explicitly built into an introductory college astronomy course through the theme of "Who Speaks for Earth?"…

A play-based approach to STEAM (science, technology, engineering, arts, and mathematics) that centers joy and imagination is fundamental to teaching young students about environmental civic engagement. In turn, diverse young learners of underrepresented backgrounds also need bilingual and bicultural mentors and role models to demonstrate that the…

In undergraduate classrooms, a majority of chemistry discoveries introduced are by white men and a small group of white women. There is greater online representation of chemists of diverse backgrounds, but the emphasis on diversity is mainly based on a monthly theme from Black History Month to Women's History Month. The "Diversity in…

While technology advancement and scientific innovation have created new topics and fields of inquiry in STEM education, external content experts such as university scientists/researchers have been increasingly involved to enhance K-12 teachers' disciplinary understandings and professional development (PD). However, few studies have scrutinized…

Language that uses noun labels and generic descriptions to discuss people who do science (e.g., "Let's be scientists! Scientists discover new things") signals to children that "scientists" is a distinctive category. This identity-focused language promotes essentialist beliefs and leads to disengagement from science among young…
