Adults must be alert to sexed-up images targeted at very young girls

ZOSIA BIELSKI

Globe and Mail; Published Tuesday, Jun. 09, 2009 4:00AM EDT; Last updated Thursday, Mar. 10, 2011 4:25PM EST

They troll gossip blogs, pore over Miley Cyrus videos and eyeball toy store shelves. They’re not preteens, but a crew of early childhood educators on a mission: to show parents and teachers what their five- to 11-year-old charges are ingesting.

The educators from the University of Toronto’s Ontario Institute for Studies in Education are meeting with teachers across North America to drive home the message that consumerist culture is sexualizing girls, and early onset puberty is worsening the problem.

The educators want to deepen elementary school teachers’ understanding of media. They will present their research, entitled the Pink Project, at a U.S. National Association for the Education of Young Children gathering in Charlotte, N.C., next week.

Early childhood education specialist Kimberly Bezaire spoke to The Globe and Mail.

Why are you looking at girls aged 5 to 11 specifically?

There’s so much research on teens and that three- to five-year-old range, but so little from 5 to 11. Biology and branding are really changing the ways these girls are growing up today.

 

What do you mean by biology changing?

Accelerated puberty – early onset puberty. It’s commonplace now for a certain percentage of girls to be having their period when they’re 8. We still haven’t gotten a clear answer on that one. Body mass index is one of the speculations, and also environmental conditions. Then it’s coupled with acceleration in social maturity and high achievement pressures. Girls excel but it’s a double-edged sword: Along with that comes an obsessive perfectionism.

 

You look at digital characters. What do you mean by that?

Miley Cyrus, the G-rated [actress] on Nickelodeon who seems so wholesome – she doesn’t stand alone: There’s Hannah Montana, clothing, products, YouTube videos, her Vanity Fair photo, her fashion photos in all the tabloid magazines, and there’s 24/7 access to those things. [Colleague] Shelley Murphy wanted to be Laurie Partridge when she was growing up. The most personal information she could learn was her star’s height, weight and favourite toothpaste. Now, the girls mine and know every single little detail – who [Ms. Cyrus] is dating, what she wants to wear and buy, who she’s posed in her underwear for, what picture she took in the shower to send to which boy and that she wants to have breasts like Katy Perry. We found from our interviews with parents that they often aren’t aware of the extent of information their girls know and make sense of.

 

And how do they make sense of it?

That’s the complicated question. Making a YouTube video of yourself in a push-up bra and a tank top when you’re 10 years old and having adult men subscribe to your [channel] – that’s what we’re seeing. They’re looking at media role models and imitating. What are the deeper spiritual and mental health implications to your identity? What are the girls spending their time, money and energy on, that could be spent on other things?

 

You look at clothing. What stood out?

We’re hearing from parents that it’s hard to find neutral, innocuous clothing. It’s all pretty, pink, sparkly and sexy. There’s a lot of trash talk on the clothing. We saw skinny jeans for babies at the Gap. We’re seeing high heels and thongs, belly shirts, low-rise jeans and wedge heels. How did we get to this point, the pornification of little ones? How did we get used to it, and who is the audience? The feminist theory that it’s the male gaze doesn’t quite satisfy us.

 

What about toys?

The Bratz are so explicitly sexualized that [children’s book publisher and distributor] Scholastic has banned them. They had a brand called Rock Angelz and they come with a groupie van. It had a bar and hot tub. There’s nothing subtle about it and they’re calling them toys – toys for what? … From our workshops, teachers really do question why parents buy this stuff. It’s easy to get into simplistic judgment but we hear from moms that it’s hard to say no. It’s a constant barrage and the cross-marketing is complex.

 

How is this script affecting their relationships?

Some immediate effects are a disruption between girls and their parents, who report a lot of conflict and pressure. Regarding friendships, teachers report these themes disrupting classroom learning and play as early as Grade 1. This sexualized curriculum disrupts important opportunities to develop social skills and self-esteem. The implications relate highly to the development of a relationship with the self: knowing who you are and what your value is, regardless of style, accoutrements, social status, attention and posing. I’m interested in knowing more about how fathers, stepfathers and grandfathers are making sense and responding – or not – to all of this.

 

What are you hoping to change?

We’re curriculum theorists. For schools and teachers, we want to position these issues as a curriculum that we can think critically about. The next step will be setting up a blog space where the teachers who have been involved can continue to be co-researchers and contribute to a tipping point.

 

What’s your advice for parents?

We caution against sticking one’s head in the sand and figuring, ‘This is just a free-for-all.’ But we also wouldn’t suggest banning pop culture texts altogether. What we know is that children learn about themselves and the world in the context of their family, school and culture. When we engage with our kids about this stuff, we create opportunities to communicate our own values. We secure our position as role models when we engage.

 

 

 

 

Parents and Their Role in their Children’s Education

From: Social Science Research Skills

 

Purpose:

The purpose of this activity is to:

– describe the diverse ways in which aspects of the school environment contribute to the socialization of individuals at various stages of the life cycle

– demonstrate an understanding of the impact that parental involvement in schools can have on a child’s growth and development

– describe creative approaches to fostering parental involvement in schools

 

 

The Process:

· You will work either individually or in a small group (three to four people) and then each complete an individual report to summarize your results.

 

Part One

· Choose one stage of the school system you will investigate:

· Preschool

· Junior/Senior Kindergarten

· Primary (grades 1 – 3)

· Junior (grades 4 – 5)

· Middle School (grades 6 – 8)

· Secondary School (grades 9 – 12)

· Conduct a literature search using the Internet and periodicals. Your goal is to gather secondary research on the role that parents play in the education of their children. Ensure that you keep track of where you found all of your research. You will be required to cite all of your sources and give credit using the APA style of citation.

 

Part Two

· Conduct primary research. Your goal is to answer the research question

“What role do parents play in the education of their children?”

· Determine how to gather information and who the sample will be. You may decide to interview parents of children in your selected group, teachers and administrators, parent volunteers (e.g., Home and School Association, Parent Council) or students. To keep your study manageable, choose ONE segment to research.

· You will need to determine your best method (tool) of information gathering – survey, interview, observation or a combination of these methods.

· Create a research tool that will be distributed to the sample you selected above.

· Follow the guidelines given in class about creating your research tool. Your teacher must approve your sample and research tool before it is administered.

· Each student in the group must be involved in the administration of the survey. When conducting your primary research collection it is important that you respect an individual’s choice to respond to an interview/survey with “no comment” or “no response at all” as a valid answer. Some people will prefer not to participate in your research.

 

Part Three:

After the primary research is brought back to class your group will tally the data. All groups’ members should have this information.

 

Write a three-page report that will include the following:

 

Part A – Introduction and Method

· A brief summary of the method and sample used for your primary research

 

Part B – Results and Discussion

· Summarize findings, draw conclusions, and identify similarities and differences between your secondary research and primary results.

· Did you notice any differences between the males and females that you surveyed? Ages of students?

· How does the information collected in your survey compare to the material presented in the book and in other secondary sources? How are they similar or different? Why do you think the similarities/ differences exist?

· Are there any views that you find surprising?

· Based on your research answer the question “What makes for an effective school?”

 

Part C – Conclusion

· Examine your research and identify its the implications. What does your research say about the role that parents play in the education of their children?

· Based on both your primary and secondary research create a list of creative approaches to fostering parental involvement in schools. Ensure that your suggestions are realistic and appropriate to the age group you are investigating.

Issues in Human Growth and Development

Summative Assignment (CCT)

 

 

PROCESS:

You will choose a topic/issue in human growth and development – it may be an issue discussed in class, or one of your own choosing. It may NOT be a topic that you have previously completed a project on.

1. Identify the issue and the developmental stage to which the issue is most relevant (some issues may touch several developmental stages, but please focus on just one stage for this assignment).

2. Connect this issue to a developmental theory or framework discussed in class, and explain how this theory is related to the issue.

3. Explore the growth or development issue in greater depth – use the research plan to guide your research and help focus your topic to determine what aspect of the topic you will examine.

4. You will present the results of your research (which may include primary sources such as surveys, questionnaires and interviews as well as secondary sources) in both an oral presentation and written presentation. You will choose how your work will be divided between these two components.

 

PRODUCT: There is a written and oral component to this product. The general expectation is a 5-7 minute presentation, and a written product that represents an approximately 2000 word essay.

You may choose to scale up or down in terms of your oral presentation – a longer oral presentation will result in a smaller written product and a shorter oral presentation will result in a larger written product. If you chose to demonstrate your learning with a product that is more of a “thing” you will need to provide a smaller written component outlining the theoretical connections.

 

You will meet with your instructor to decide (in writing) what your written/oral division will be and what the expectations for the written product will be.

Your product may be one of the following:

· 2000 word essay

· scrapbook

· artwork & explanation

· brochure

· learning activity for the class

· a review of a selection of articles
