![]() ![]() We will illustrate the adaptation of several sample lessons to achieve three key outcomes: (1) to support and reduce harm to LGBTQ students, (2) to engage all students with inquiry into science in society, and (3) to develop student empathy toward diverse identities and perspectives. This article will outline a thinking framework that any teacher can use to adapt curriculum through a lens of gender diversity. When we teach anatomy and physiology, we can expose students to data that challenges the notion of binary “male” and “female” bodies, and validates the complexity of human experience. When we teach evolution, we can include diverse animal reproductive strategies that make for captivating case studies. When we teach genetics, we can highlight the complexity of genetic sex determination to add depth, rigor, and relevance to the lesson. Inquiry lessons, by nature, allow students to create and discuss claims from evidence, and this can include claims about gender. High school biology teachers have rich opportunities to include gender diversity in our teaching. ![]() Lack of inclusive curriculum also impacts students’ career pathways-LGBTQ high school seniors who saw positive LGBTQ representation in science class were 17.3% more likely to choose a STEM major ( n = 1124 Kosciw 2014). Yet this is exceedingly rare in science classes, with only 2.4% of LGBTQ students seeing any LGBTQ-inclusive science content in 2017 ( Kosciw 2018). When a school implements LGBTQ-inclusive curriculum, students report less victimization, less absenteeism, and more positive relationships with their teachers ( Kosciw et al. 2018).Įven teachers actively working against bullying may be surprised to learn about the impact of LGBTQ-inclusive curriculum on youth safety and learning. Yet schools remain a place where youth experience daily bullying and harassment on the basis of sexual orientation or gender expression ( Kahn et al. On television, one in 10 characters in the 2019–2020 broadcast season was LGBTQ ( GLAAD 2020). Public awareness has grown to a point where 27% of Americans know someone who is transgender, and 45% view gender as a spectrum rather than a binary ( n = 1306 Carmichael 2020). 2018) and at least 0.7% identify as transgender ( Herman et al. Among youth ages 13–18, 10.5% identify as lesbian, gay, or bisexual ( Kahn et al. "The ability to not only observe, but to measure dynamics of undisturbed living cells, through the application of quantification techniques to holo-tomographic microscopy, is likely to lead to discovery of fundamentally new cell behaviors, and new understanding of previously studied phenomena as well," Frechin said.Now that gender and sexual diversity are more visible than ever, our science curriculum must adapt to serve our students and prepare them for the future. Here, in the run-up to mitosis (the stage of the cell cycle in which the nucleus divides in two), the researchers show that the entire nucleus rotates between 80 and 700 degrees over a period of minutes to hours. ![]() The ability of the microscopic technique to capture data from the entire cell simultaneously allowed the authors to provide important new information about the intriguing but little-understood process of organelle spinning. Applying their techniques, they quantified for the first time the flux of fat droplets within a whole cell, measuring their rate of formation and changes in mass over time, and revealing new aspects of their dynamics, including the synchronization of swelling among a subset of droplets. In the current study, the authors applied multiple image-processing techniques to extract quantitative data from their holo-tomographic images. The whole process is done without dyes and at very low levels of light, preserving the structural and behavioral integrity of the cell during image capture. By tipping the sample, multiple such images can be combined to create a three-dimensional picture of the cell. When the two parts are recombined, differences in their wave forms can be used to create an image based on differences in the refractive index of the cell's components. ![]() A wide variety of techniques is available to study living cells, but many of them have intrinsic limitations, such as the need for damaging levels of light, or the use of interfering dyes, or poor contrast and resolution.Ī relatively new form of microscopy, called holo-tomographic microscopy, surmounts some of these limitations, by splitting a light beam, diverting one part and letting the other pass through the sample. ![]()
