Encouraging Girls in STEM subjects

KimJonesimageBy Kim Jones, CEO, Curriki

While girls show a lot of interest in science during elementary school, the interest often fades in the later grades. Around 2/3 of girls in the U.S. at the fourth grade level express an interest in science and/or math subjects.

U.S. Census Bureau statistics indicate that about 24% of the jobs in STEM (science, technology and math) fields are currently occupied by women. The gender imbalance is particularly notable in the physical sciences and in engineering fields, while women are better represented in the life sciences.

In computer science there is a very large imbalance, and yet this is a field where many jobs go begging today – there are hundreds of thousands of software development jobs in the U.S. in this field which are unfilled at present.

Verizon has developed a wonderful “Inspire Her Mind” commercial -

The message of the commercial is – don’t discourage girls from “getting their hands dirty” with science or engineering projects. Rather, encourage their curiosity and their interest in these fields.

Curriki contains a wealth of resources in STEM subjects, even full courses in math including algebra and geometry. And of course developing math strengths is key to pursuing majors and careers in science and technology fields.

Here’s information on one project to address the gender gap in software development – it is a global effort to teach 1 million girls to write computer code and develop applications.

http://www.cnet.com/news/girl-geek-academy-wants-to-teach-one-million-girls-to-code/

As CNET reports: “A new initiative aims to teach women how to create apps and launch their own startups, with the aim to reach one million people by 2025″. There has been progress in certain areas. For example, the number of women involved in the gaming industry, one of the largest for new software development opportunities, has increased from 11% to 22% in recent years.

Here’s an article about Women Who Code UK founder and software engineer Sheree Atcheson, who is just 23 years old.

Curriki also has resources to help girls, and boys, learn to code, including the Oracle Academy courses for Java, one of today’s most important programming languages.

Curriki’s purpose is to broaden educational opportunity in K-12 for students in all countries, including supporting greater participation by girls in the various STEM fields. These fields are so critical to future job opportunities for students and to the progress of humanity around the world, whether through the life sciences, physical sciences, or engineering.

National Museum of Mathematics

By Janet Pinto, Chief Academic Officer

At Curriki, we believe that math does not have to be boring. One institution that shares this belief and brings it to life is the National Museum of Mathematics (a.k.a. MoMath) in Manhattan, New York City. It is the only museum in the U.S. devoted purely to math.

Science News said the museum is “the antidote to math phobia”. MoMath stresses interactive exhibits so that one can gain an understanding of math concepts by doing and exploring.

Image

According to the MoMath website: 

The National Museum of Mathematics strives to enhance public understanding and perception of mathematics. Its dynamic exhibits and programs will stimulate inquiry, spark curiosity, and reveal the wonders of mathematics. The Museum’s activities will lead a broad and diverse audience to understand the evolving, creative, human, and aesthetic nature of mathematics. 

Image

The museum was established at the end of 2012 to promote the understanding and importance of mathematics, and to present math concepts in a fun and engaging way. A particular focus is placed on kids in the middle grades (4th grade through 8th grade) but there are attractions for kids of all ages and adults as well.

In addition, there are a large number of lecture videos on various math topics available at the MoMath web site and on YouTube as well, go to http://momath.org/gallery/ to access these.

The museum’s approach is compatible with the principles behind project-based learning. Curriki has developed two mathematics courses built around the project-based learning methodology. These are for Algebra and Geometry and can be accessed here:

Algebra course = http://www.curriki.org/xwiki/bin/view/Coll_kathyduhl/Algebra1

Geometry course = http://www.curriki.org/welcome/resources-curricula/curriki-geometry-course/

If you live in or happen to visit New York City, we encourage you to take your class or your own children to visit the National Museum of Mathematics. You’ll probably have fun too!

Girls and STEM: Bias begins with Toddlers?

KimJonesimageBy Kim Jones, CEO, Curriki

Even when girls and boys demonstrate similar actual competence levels in math, during the early school years, boys are more confident about their math skills. Already by kindergarten, boys have more interest in pursuing math learning than do girls.

Image

STEM (science, technology, engineering and mathematics) related jobs are some of the best jobs out there, and increasingly important in our technology-driven economy. But the percentage of women in many STEM jobs remains very low. Only about 1/4 of STEM jobs in the U.S. are filled by women. Women’s share of computer jobs has actually been falling in recent years. At present, only 18% of U.S. computer science majors are women.

According to the Office of Science and Technology Policy, women in STEM professions earn 33% more than those in other fields.

Image

It’s generally understood that by school age, girls receive less encouragement in math and science pursuits than do boys, from both parents and teachers. What’s interesting is that it now seems this bias starts from a very early age, less than the age of 2 years!

In a study entitled “Gender Biases in Early Number Exposure to Preschool-Aged Children”, published in 2011 in the Journal of Language and Social Psychology, researchers at the University of Delaware found that mothers spent fully twice as much time talking to their sons about numbers and numeric concepts as they did with their daughters! The average age of the children in the study was only 22 months, for both the boys and the girls.

Here’s a related set of resources on Curriki – Math for Girls. This link includes a series of videos featuring women working in mathematics and presenting pieces of math that excited them when they were in middle and high school.

Help girls realize that math and sciences education is not just for the boys. Even if they don’t end up pursuing STEM careers, there is a lot of useful and interesting knowledge to be gained in studying math, science and engineering topics. The use of math in traditionally non-STEM careers, such as finance and marketing, is only increasing. And maybe they are better at math than they think they are!

You’ll also find other resources at this link including profiles of women in Math, and in STEM careers in general.

Different Learning Approaches Prepare Students at Warrior Tech Academy

pbl

By Janet Pinto, Chief Academic Officer, Curriki

janetpic_preferred_cropped

We’re big advocates of Project-Based Learning, which we’ve written about in previous blogs, so we were pleased to see that it’s at the core of the instructional approach at the first New Tech Network (NTN) school in Virginia.

Warrior Tech Academy (WTA)  will soon open as a school-within-a-school at Magna Vista High School in Virginia, where students will work in groups with teachers guiding them. WTA will combine different ways of learning to best meet the needs of their students.

Warrior Tech will employ project-based learning (PBL) in its integrated World History 1/ English 9 course and the integrated biology/health and physical education course, but its math course will be taught using problem-based learning (PrBL).

Many of us are familiar with project-based learning, which teaches both doing, as well as learning, and gives students real-world opportunities to think analytically, formulate ideas, and solve complex problems. But do you employ problem-based learning in your classroom?

According to WTA geometry facilitator Jeannie Stanley, “Problem-based learning begins with a problem that encompasses one to two standards and takes only a few days to complete, but project-based learning focuses on multiple content standards and takes several weeks to complete.”

These different learning approaches are especially important as we groom students to succeed in the real world.  In this article , Henry County Schools Superintendent Jared Cotton said county students do well on state Standards of Learning tests, which are multiple choice, but employers and higher education officials say graduates need better skills in critical and creative thinking, communication, collaboration and problem-solving.
