In the field of engineering,men hold most of the jobs.But DiscoverE wanted to change that.On February 25, DiscoverE,known as the National Engineers Week Foundation,celebrated its annual Girl Day.

Although women fill close to half of all jobs in the US economy,they hold less than 25% in the fields of science, technology,engineering,and math (STEM),according to the US Department of Commerce.The agency also reported women hold a low share of college degrees in these fields,particularly in engineering.

With such a large gender gap in STEM jobs,DiscoverE wanted to demonstrate to girls the different fields available to them.It also intended to disclose the various myths that may be causing girls to shy away from this line of work.Valecia Maclin,a director of Raytheon,a technology company and one of DiscoverE's corporate partners, addressed the three most common myths about engineers.

Myth # 1: Engineers aren't creative.

According to Maclin,the opposite is true."Engineers need to be very creative in order to solve problems," she says.And girls,Maclin adds,are great at problem solving.

Myth # 2: You'll be the only girl in your engineering class.

Maclin admits there're usually very few girls in engineering classes.Such was the case in her own experience, but rarely will there be only one girl in the class.She believes this can work in favor of girls.

Myth # 3 :You'll get paid less than the male engineers.

According to the US Department of Labor,women working full time only make about 79% of what men earn. However,STEM careers are in such high demand that even starting salaries are high. "In engineering,your performance is the driving force behind what you get paid,regardless of your gender," Maclin says.
