    Gender and Sexuality in the High School Biology Classroom:

Fostering Critical Thinking and Active Engagement

 

Summary: This project was undertaken with the hope of changing the ways we think about teaching and engaging with science. This paper will discuss ways to help students recognize that science is interdisciplinary and can both affect and be affected by the social and/or political context it exists in.  

By asking students to think about the way science is presented and conducted, and giving them the tools to think about science not as an isolated body of information, but as a dynamic and shifting discipline, we will not only be encouraging more engaged science scholarship, but will also help students begin to notice the ways science is used as evidence in different contexts and evaluate these uses.

Objective:

The goals of this project are two-fold. I hope to suggest ways for biology teachers:

Presenting on Intersexuality-- A Template

Submitted by Katie Randall on Mon, 10/31/2011 - 10:28pm

After our unit on De/Meaning Sex and Gender, I knew I wanted to focus my web event on intersexuality. It’s a form of biological diversity of sex which most people don’t hear about until college, and many not even then.

So I started thinking—when would it make sense for students to first be introduced to intersexuality in an academic setting? I thought back to my own education in biology and the answer, to me, was middle school. In my middle school we had a unit in biology class which was basically “puberty education,” although I don’t remember what its official title was. We learned about the physical changes that male and female bodies go through in puberty—in other words, the changes our own bodies were going through right then. This would have been the perfect time to mention that not everyone would exactly fit into one pattern or another—that chromosomal sex, primary sex characteristics, and secondary sex characteristics don’t always match up. But this was never covered—not in middle school, high school or beyond.

I know that not everyone is given information about sex characteristics or the reproductive system in middle school, or even later. But to me the timing felt right.

I included the permission slip because I think that for many schools this would be part of the process of giving such a lecture.

A response to “Miss Representation 8 min. trailer:” Changing gender stereotypes by increasing visibility of female athletes

Submitted by jmorgant on Sun, 10/30/2011 - 8:13pm

The trailer for Miss Representation by filmmaker Jennifer Siebel Newsom describes the power of the media, acknowledging that people learn more from it than any other single source of information. The media is the primary force that shapes our society: “politics, national discourse, and children’s brains, lives, and emotions” (Jim Steyer, CEO, Common Sense Media). Upwards of one billion people use the Internet every day (Marissa Mayer, Vice President, Consumer Products, Google); images are widely available and accessible without restrictions.

 

The messages disseminated by the mainstream media are pervasive, and more often than not emphasize and perpetuate harmful gender stereotypes. According to Miss Representation, women hold only 3% of clout positions in telecommunications, entertainment, publishing and advertising and comprise just 16% of all writers, directors, producers, cinematographers and editors. Because women are generally not the ones deciding how they are represented in the media, they are often shown as sex objects, valued by their looks rather than their achievements. As a result, “girls are taught that their value is based on how they look, and boys are taught that that’s what’s important about women” (Jean Kilbourne, EdD, Filmmaker, Killing Us Softly).

Dear Middleschoolers, Love, Charlie

Submitted by charlie on Sun, 10/30/2011 - 2:50pm

Dear boys, girls, and those of you who just aren’t quite sure yet (because that is totally cool too),

            For many of you, this is a confusing time. Things are growing in places where you aren’t sure if they are supposed to be growing, new places might develop novel smells, and you might start to feel differently. If any of these things apply to you, or if none of these things apply to you, you are still normal. Every body goes through different changes at different speeds and in completely different orders. So if your best friend is growing armpit hair, but you haven’t reached that point yet, don’t worry – we all catch up in the end! I am writing to you, middle-schoolers, because this time can be a bit scary; there are a lot of changes that you can expect in the next couple of years, and a lot of information out there, both true and false, so a quick guide to the next few years seems like a pretty good resource for you right about now. Read on to learn about what makes boys and girls different biologically, some of the changes that you can expect to your body during puberty, how babies are made, and a quick peek at the different categorizations of gender!

Let’s start from the very beginning. How did we get here and what exactly makes girls different from boys?

Should You Drink Sports Drinks? When? Why?

The questions in this activity help students to understand the effects of consuming sports drinks and when and how the consumption of sports drinks can be beneficial or harmful. This activity provides the opportunity to review some basic concepts related to osmosis, cellular respiration, mammalian temperature regulation, and how our different body systems cooperate to maintain homeostasis.

 The first and third attached files have the Student Handout and the second and fourth attached files have the Teacher Notes.

Molecular Biology: Major Concepts and Learning Activities

This overview reviews key concepts and learning activities to help students understand how genes influence our traits by molecular processes.  Topics covered include basic understanding of the important roles of proteins and DNA; DNA structure, function and replication; the molecular biology of how genes influence traits, including transcription and translation; the molecular biology of mutations; and genetic engineering. 

To help students understand the relevance of these molecular processes, the suggested learning activities link alleles of specific genes to human characteristics such as albinism, hemophilia, sickle cell anemia and muscular dystrophy. Suggested activities include analysis and discussion activities, hands-on laboratory and simulation activities, web-based simulations, and a vocabulary review game.

This activity is aligned with the Next Generation Science Standards. The attached files have the overview of key concepts, with descriptions of relevant learning activities and links to the activities. 

What types of mutations cause more vs. less severe muscular dystrophy?

This analysis and discussion activity begins with a brief video presenting the anchoring phenomenon – a teenager who has Duchenne muscular dystrophy.

Then, students investigate the types of deletion mutation that cause the more severe Duchenne muscular dystrophy vs. the milder Becker muscular dystrophy. During this analysis, students review transcription and translation, learn how to use a codon wheel, and analyze the molecular effects of different types of deletion and point mutations.

Finally, students investigate X-linked recessive mutations to understand why almost all Duchenne muscular dystrophy patients are male.

The Student Handout is available in the first two attached files and as a Google doc designed for use in online instruction and distance learning. (For additional instructions, see https://serendipstudio.org/exchange/bioactivities/Googledocs, especially item 7.) The Teacher Notes, available in the last two attached files, provide instructional suggestions and background information and explain how this activity is aligned with the Next Generation Science Standards (NGSS).

DNA Function, Structure and Replication

DNA structure

In this analysis and discussion activity, students learn the basics of DNA function, structure, and replication.

The sequence of nucleotides in a gene determines the sequence of amino acids in a protein, which determines the structure and function of the protein. Different versions of a gene give the instructions to make different versions of a protein, which can result in different characteristics.

Since many different proteins are needed for a cell to be alive, each cell needs a complete copy of the DNA with all of the genes. Therefore, before a cell divides, it needs to make a copy of all its DNA. Students analyze DNA replication to understand how the double helix structure of DNA, the base-pairing rules, and DNA polymerase work together to produce two identical copies of the original DNA molecule.

This activity can be used to introduce your students to key concepts about DNA or to review these concepts.

Molecular Biology Vocabulary Review Game

This game helps students to enjoy reviewing vocabulary related to molecular biology, including DNA and RNA structure and function, transcription and translation. Each card in the deck has a target vocabulary word and two related taboo words that the student may not use as he/she gives clues so the other students in his/her small group can guess the target word. Many students have trouble learning the substantial new vocabulary required for biology, and this game lets students have fun while reinforcing their understanding of key terms. 

The first file below provides the master copy for creating the card decks for this game, and the second file below provides the teacher notes, including instructions for playing the game.
