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.


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.


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


By Janet Pinto, Chief Academic Officer, Curriki


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.

Curriki Project-Based Geometry & Algebra Courses Available Free


Curriki offers geometry and algebra courses that leverage the popular project-based learning “active” approach and are aligned to Common Core State Standards. Designed to meet the needs of students born in a global, interactive, digitally-connected world, these courses encourage learning through the use of real-world examples, engaging projects, interactive technologies, videos and targeted feedback.

The Curriki Algebra course is available here.

The Curriki Geometry course will be available in September 2013. To participate in the beta launch, sign up today.

(These courses were sponsored by AT&T and developed by Curriki.)

Getting the Most out of Technology

KimJonesimageBy Kim Jones, CEO, Curriki

A recent article from the NY Times discussed the use of computer technology in schools. The question posed is: are we really making the most of the technology already deployed? A survey found that, in many cases, computers were being used in mathematics simply to drill questions and answers. The article is here. It notes that “the nonprofit Center for American Progress found that middle school math students more commonly used computers for basic drills and practice than to develop sophisticated skills.”

At Curriki we all come from the IT industry, and we know that the potential of technology is much greater than usage of computers in a fashion that is twenty five years behind the times. This is why we provide a wide variety of free, open source, K-12 focused educational resources, that often make significant use of technology. For example, there are over 1300 mathematics related videos at www.curriki.org.

As another important example, we have been developing complete subject curricula that are project-oriented and adhere to Common Core State Standards.

We have already released the free Curriki Algebra 1 course, which you can find on the Curriki site here. It consists of 5 units aligned to the Common Core. Each of these units culminates in a project that utilizes mastery of conceptual understanding taught in the individual lessons.


And we have announced a free, online, project-based Curriki Geometry course. This is under development with support from AT&T and will be released in the autumn of this year. Here is the announcement. The course will be structured based on the six Common Core High School Geometry topics, organized in six units including: (1) Congruence; (2) Similarity, Right Triangles, & Trigonometry; (3) Circles; (4) Expressing Geometric Properties with Equations; (5) Geometric Measurement & Dimension; and (6) Modeling with Geometry.

Please take a look at the Curriki Algebra 1 course, and stay tuned for the Curriki Geometry course release this autumn.

Khan Academy in the New World of Common Core Standards

janetpic_preferred_croppedBy Janet Pinto, Chief Academic Officer, Curriki

An intern at Khan Academy recently asked for suggestions on a Reddit education site. There was some interesting discussion in response around the efficacy of Khan Academy videos and how these video resources relate to Common Core standards.

One commenter notes that it is harder to grade and check answers with this approach. Another points out that math and science topics are more objective, so potentially more amenable to the use of short video lessons than say, history. “Dr. Momentum” responds that even math and science still involve opinions.

ImageStudents need to be able to understand a logical argument, construct a logical argument and refute an incorrect argument. Students need to develop their own reasoning ability. And coherence and depth in teaching a subject, not just subject knowledge, are required from their teachers.

One commenter points out that the Common Core standards for math include Mathematical Practices as well as Mathematical Content. Indeed, Khan Academy is good for the procedural side of things, and in conveying content. Practice transmission, on the other hand, just doesn’t happen on its own, and it’s not enough to explain procedures. It’s about developing expertise in students – “reasoning ability, conceptual understanding and procedural fluency,” among other attributes.


Here are the 8 practices for Math, which you can find at http://www.corestandards.org/Math/Practice -
MP1: Make sense of problems and persevere in solving them.
MP2: Reason abstractly and quantitatively.
MP3: Construct viable arguments and critique the reasoning of others.
MP4: Model with mathematics.
MP5: Use appropriate tools strategically.
MP6: Attend to precision.
MP7: Look for and make use of structure.
MP8: Look for and express regularity in repeated reasoning.

Attention to how a student is thinking and attempting to reason is not something a video can do. Don’t get us wrong, we love the Khan videos, and there are many of them accessible from Curriki.

It’s about the connectedness. One can pick up a procedure or three, but until one has the ability to generalize then the subject matter is not really being understood sufficiently. While some students have an innate ability to do this, most will benefit from coaching and development and assistance in seeing the larger context.

The Curriki Algebra 1 course found here is designed to align with Common Core State Standards.
