The common denominator for entry into most STEM (science, technology, engineering and mathematics) majors is the ability to successfully complete high-level math courses. There is no getting around this requirement in order to obtain degrees in majors like engineering, computer science and chemistry.
There may not be one magic bullet that will increase the diversity of students in STEM majors, but placing a laser-like focus on academic achievement in mathematics will help more students get past gatekeeper courses like calculus.
Universities can design and/or expand summer bridge programs that focus extensively on building competency in mathematics for students who are interested in majoring in STEM fields but lack strong math backgrounds. They can also dedicate funding streams to support summer school learning opportunities for current students who need to catch up on math courses in order to stay on track to graduate within four years.
An accelerated level of peer-to-peer tutoring opportunities and other wraparound support services would also be helpful. It will ultimately be up to students to take the initiative to utilize these services.
Students must have the will and desire to get over the roadblocks they will inevitably encounter in these courses. They need a consistent support system to encourage them to not get weaker but to dig deeper.
Many students doubt themselves and lack confidence in their ability to successfully complete higher level math classes. These feelings cause some to give up on majors like engineering before they even begin. There should be efforts to build academic swagger in them to help them overcome mental barriers that they may have set for themselves.
There is an assortment of partnerships and varying mechanisms of engagement that higher education institutions have with K-12 educational systems. Most engagements should be applauded and supported. There is, however, a need to strategically target these efforts. Some colleges and universities have random and sporadic engagement that may not be focused on the most pivotal areas of need.
