# The Interconnected Nature of STEM Subjects in Education
Written on
Chapter 1: Understanding the Broad Field of Science
In public education, students encounter a wide array of subjects, notably the expansive domain of Science. This field is termed "broad" due to its inclusion of various disciplines, such as Biology, Chemistry, Geology, Philosophy, Physics, Psychology, and more. When these scientific areas are integrated with Mathematics and Engineering, they collectively form the STEM framework.
While educational curriculums incorporate these subjects, they often overlook the interconnections that can enhance learning. In my view, certain courses should precede others to establish a foundational knowledge that benefits students in their educational journey.
Section 1.1: The Importance of Mathematics in Physics
A common saying goes, “Physics is applied Mathematics,” which holds considerable truth. Physics employs mathematical principles to explain natural phenomena rather than remaining confined to theoretical concepts. Thus, it follows that Mathematics should be taught before Physics.
Students may not need to master calculus to grasp Physics; however, a solid understanding of topics up to pre-calculus is essential. During their math courses, learners might encounter physics-related problems, such as calculating the collision of two cars approaching an intersection from different distances. Although they may not initially recognize the relevance of trigonometric functions in describing oscillating springs, this mathematical foundation prepares them for future challenges in Physics.
But what about the role of Calculus? Indeed, many physics problems involve calculus concepts. Physics instructors can provide brief insights into derivatives and integrals, allowing students to concurrently study Calculus alongside Physics.
Section 1.2: Physics as a Foundation for Chemistry
I advocate for students to study Physics prior to delving into Chemistry. The previous maxim continues with, “Chemistry is applied Physics,” which is also accurate. Introductory Physics covers topics like acceleration, velocity, forces, and moments. Concepts such as power, pressure, and kinetic energy within Newtonian mechanics describe the behavior of moving (or stationary) objects.
Understanding energy is crucial for Chemistry, as it delves into how various forms of matter can undergo changes, either physical or chemical. This foundational knowledge is demonstrated dramatically in shows like Breaking Bad, where the significance of energy in chemical reactions is highlighted.
Chapter 2: Chemistry’s Role in Understanding Biology
The earlier adage extends further: “Biology is applied Chemistry.” This holds true since cells and organisms are formed from matter. A fundamental grasp of Chemistry equips students with a micro-level understanding of biological entities. For instance, while the human body comprises various cell types, these cells themselves are made up of diverse molecules, primarily water.
I hold a slightly less rigid stance on this sequencing compared to the previous subjects, but I believe that a solid foundation in Chemistry can significantly enrich a Biology curriculum.
Section 2.1: The Value of Psychology in Journalism and Criminal Justice
Lastly, I propose that studying Psychology should precede courses in Journalism or Criminal Justice. The rationale lies in the nature of these fields, which often require interviewing individuals to gather perspectives or accounts of events. In reality, these interactions are seldom straightforward due to various complexities.
For instance, eyewitness testimonies are notoriously unreliable; people often misremember details, leading legal systems to question their validity. Furthermore, individuals may have personal motives for misrepresenting facts, a point illustrated in Clint Eastwood's 1999 film True Crime.
A deeper understanding of human behavior, including the impact of mental disorders on perception, is crucial for anyone pursuing Journalism or Criminal Justice. As individuals engage more with scientific inquiry, they come to appreciate the inherent unreliability of human testimony, making this knowledge essential for their future endeavors.
