How case-based learning can build enthusiasm for a forensic science career

The Department of Labor predicts there will be a 17 percent increase in forensic science jobs between 2016 and 2026

It is estimated that these government laboratories have a case backlog of 570,100 requests for forensic services.

Since 2000, there has been a major initiative at all levels of educational institutions in the United States – from K-12 to colleges and universities – to promote student interest in STEM (science, technology, engineering and math) coursework. STEM includes the study of physics, chemistry and life sciences (i.e., biology, anatomy and anthropology), along with math and engineering.

However, despite these efforts, there appears to be a continuous deficit in students entering the science fields. The U.S. National Academies reported in Rising Above the Gathering Storm that there is a deficiency of scientists in the United States. According to Wagstaff and LaPorte, STEM interest suffers from a phenomenon known as the “leaky pipeline.” Students start out pursuing science degrees but transfer to other degree programs, which contributes to low STEM completion rates. Dropout rates are higher for females and minorities, contributing to disproportionately low percentages of women and minorities working in science fields:

  • Females constitute 50 percent of the population; 30 percent work in the sciences;
  • Hispanics constitute 17 percent of the population; 6 percent work in the sciences;
  • African Americans constitute 13 percent of the population; 5 percent work in the sciences.

Rising Opportunity in Forensic Science Careers

One area that holds great potential to garner student interest is forensic science. Forensic science is a fascinating field of study that impacts public safety by utilizing scientific theories and techniques to assist law enforcement, as well as the court system. The field has many specialties such as toxicology, entomology, DNA analysis and digital forensics that require a background in STEM sciences.

Not only is it an interesting career, but there is also a growing need for more forensic scientists. The United States Department of Labor predicts there will be a 17 percent increase in forensic science jobs between 2016 and 2026, which is much higher than the average for all occupations. With continual advances in forensic science technology, these numbers are likely to be higher than estimated.

According to Durose and Burch, more than 14,000 individuals are employed full-time by government crime laboratories. But more qualified forensic scientists are needed. It is estimated that these government laboratories have a case backlog of 570,100 requests for forensic services. Private labs are stepping in to assist with the forensic testing of evidence submitted to state and federal laboratories; however, these companies are also in need of their own qualified forensic scientists.

With the appeal of hands-on work and the clear need for more scientists in the field, forensic science would seem a natural career choice for many students. As with other STEM-based professions, it is a struggle to keep students on this career path of using science to assist with matters of law.

It is the responsibility of academic institutions and individual educators to change this trend by creating a learning atmosphere within classrooms that fosters a love for the sciences. The goal should be to encourage students to develop a passion for STEM at a young age and support their learning through high school and college, providing them with the tools needed to follow a pathway to a forensic science career.

Case-Based Learning Engages Students in Forensic Sciences

One of the best ways to create enthusiasm among future scientists is through active-learning initiatives that use case-based scenarios, which provide real-world examples of what scientists encounter in the field. Active learning is defined as “the process of having students engage in some activity that forces them to reflect upon ideas and upon how they are using those ideas.” Student motivation increases, as does their personal satisfaction and confidence, when engaged in active-learning exercises.

Case-based scenarios engage active learning as they give students an opportunity to use not only book knowledge, but critical thinking skills and group interaction to solve real or fictional criminal cases. In a study by Cresswell and Loughlin, forensic case-based scenarios were assigned to student groups of three and contained the following components:

  • Introduction to the problem;
  • Analysis of evidence;
  • Designing of testing strategies;
  • Testing of evidence;
  • Analysis of results;
  • Writing of report and witness statements.

Overall, students reportedly had a high interest in the case-based scenarios as well as the preparatory lectures that accompanied the scenario. Results of the study revealed improvement in assessment outcomes.

One of the only negative components that students reported was having to work together in a group setting. However, from an academic perspective, group work is critical to learning. It’s also critical for a career in forensics. Forensic scientists solve crimes collectively and in tandem with law enforcement, lawyers, medical examiner staff, as well as other government agencies such as Child and Family Services.

Case-based scenarios offer the possibility of grouping diverse ethnic and gender populations, which can greatly enhance the learning experience. Unique life experiences result in different approaches to critical thinking and absorption of knowledge. Research has shown “diverse teams perform better,” which holds promise in the academic arena for renewed enthusiasm in the forensic sciences as well as other science disciplines.

Academic institutions and educators must find ways to incorporate case-based scenarios and other active learning strategies into their STEM coursework. This style of learning has proven to engage students, help create a passion and enthusiasm for the sciences, and build student confidence in their ability to pursue a career in forensic science or other science-based careers.
