Ancient Skeletal Remains: Sex, Gender, And Archaeology

In this lesson for high school life sciences, students explore case studies of human remains that have challenged scientists’ ideas about how gender and sex operated in ancient times to help us better understand how gender, sex, and sexuality change our bodies and our stories in the present day.

Lewis Steller created this lesson as part of the Science Friday Educator Collaborative.

Educational Jewelry of Queer Animals at San Diego Pride 2023!

How cool is this educational jewelry that @the_fish_nerd has created! Her photos show linked medallions illustrated with non-binary side-blotched lizards, transgender moray eels, and asexual condors. Thanks for sharing! - RXS


Sex and gender are binaries? Sorry, that's a scientific falsehood

In this SF Chronicle piece, Ash Zemenick discusses evidence for biological sex as a continuum rather than a binary. They argue that humans whose chromosomes, gametes, or hormones do not fit into a binary are common and that it is more useful to view them as a form of diversity rather than as an exception to a rule.

Reebops Nursery (gender-inclusive Genetics of independent assortment)

Gender-inclusive simulation of independent assortment for a genetics or evolution lesson. Adapted from slides created by Laura Funk (staff profile page) by modifying “mom” to egg-giver and “dad” to sperm-giver. Can also serve as model for discussion about mutations, epigenetics, evolution, chromosomes, alleles, nondisjunction. See also Teach.Genetics.Utah.edu's paper-based activities. See steps below and the questions for the assessment at the end. (Originally published here in 3/17/21.)

NGSS Works towards HS-LS3-1. Follow up with meiosis and HS-LS3-2.

0. Attach completed Reebops Nursery from your Drive.

1. Name your Reebop

2. What do you think each letter represents in the model?

3. What do you think combining the letters represents in the model?

4. All models are wrong. Some models are useful. What are some things missing from this model? List as many as you can think of.

5. Gametes (egg & sperm cells) contain 1 pair of chromosomes (n = haploid), the other body cells contain 2 pairs of chromosomes (2n=diploid). Is your baby reebop haploid or diploid?

Generating a framework for gender and sexual diversity-inclusive STEM education

Generating a framework for gender and sexual diversity-inclusive STEM education

Abstract

Students who identify as LGBTQ continue to report feelings of being unsafe at school because of their sexual orientation, gender identity, and gender expression. Access to a gender and sexual diversity (GSD)-inclusive curriculum and supportive teachers may positively improve the school climate for LGBTQ students, but these supports are often not included in STEM classrooms. One response is to ensure that STEM teachers are prepared to integrate GSD-inclusive STEM teaching into their classrooms. This review systematically analyzed the literature on supporting and affirming GSD in K-12 and higher education STEM education contexts. The 81 selected studies were qualitatively analyzed using inductive thematic analysis and epistemic network analysis, and the findings showed that GSD-inclusive STEM education literature coheres around six highly related constructs: Heteronormativity, Social Justice, Epistemic Knowledge of Science and Inquiry, Identity, Embodiment, and GSD language. Identifying these constructs, and the connections among them, led to the generation of an operational framework of GSD-inclusive STEM teaching that can inform and guide STEM teacher education programs and STEM teacher professional development to develop STEM educators' equity literacy around GSD to foster bias-free, equitable, inclusive STEM classrooms.

“It’s completely erasure”: A Qualitative Exploration of Experiences of Transgender, Nonbinary, Gender Nonconforming, and Questioning Students in Biology Courses

Abstract

Biology is the study of the diversity of life, which includes diversity in sex, gender, and sexual, romantic, and related orientations. However, a small body of literature suggests that undergraduate biology courses focus on only a narrow representation of this diversity (binary sexes, heterosexual orientations, etc.). In this study, we interviewed students with queer genders to understand the messages about sex, gender, and orientation they encountered in biology and the impact of these messages on them. We found five overarching themes in these interviews. Students described two narratives about sex, gender, and orientation in their biology classes that made biology implicitly exclusionary. These narratives harmed students by impacting their sense of belonging, career preparation, and interest in biology content. However, students employed a range of resilience strategies to resist these harms. Finally, students described the currently unrealized potential for biology and biology courses to validate queer identities by representing the diversity in sex and orientation in biology. We provide teaching suggestions derived from student interviews for making biology more queer-inclusive.

[Update] Sex and Gender Inclusivity in Pedigree Nomenclature

This focused revision addresses the need to denote sex assigned at birth and gender in pedigree nomenclature. It clarifies the use of symbols and language to ensure safe and inclusive genetic counseling for people who are gender-diverse or transgender.
