How do you usually study Science?
Do you try to cover the syllabus so you can do well in exams, but often find that you have forgotten the concepts after a few weeks? Many students struggle to retain knowledge long enough to claim expertise in the subject.
Others fail to apply what they learn to real-world scenarios, including professional settings such as healthcare internships in college.
A 2024 survey by NACE (National Association of Colleges and Employers) found a sizable gap between new graduates’ and employers’ perceptions of career readiness. The gap is close to 25% for skills like critical thinking and communication. These findings strongly indicate that students may believe they are acquiring the necessary expertise in a subject, but the reality is different.
We have three practical ideas to change this scenario.
1. Practice Recall and Application in Parallel
Suppose you are studying the digestive system in Biology. Depending on your grade, you may have a wide assortment of ideas, from the various organ names to their functions and medical complications arising from malfunctioning or underlying health problems.
As you study, you may focus on recalling these concepts. Many facts surround you, and some have complicated names, like Diverticulosis (small pouches in the intestinal wall) and Barrett’s esophagus (changed appearance of esophageal lining).
To develop focused expertise, only recall won’t suffice. You also need retrieval focused on application. A 2025 study published in Learning and Instruction showed that retrieval can outperform restudy, with the effects holding over a delay period. The benefits of retrieval extend beyond just memory. They also encompass recognition, i.e., the relevance of the learned information in a new situation.
For our example on bodily functions, here’s how you can link recall to applications to retain the facts for longer and also gain a genuine edge for your future studies:
- Asking related questions. (Example: Why do pouches form in diverticulosis, and what makes them infected?)
- Connecting to real-world impact. (Example: Does a change in the esophageal lining show any symptoms?)
- Building and practicing quizzes that test both recall and application. You can do this with your tutor’s help or make a peer-to-peer study circle. Some AI-based tools can also help with generating revision assignments.
2. Develop a Concept Hierarchy That Takes You Deeper
This is a crucial skill that will keep you steady as you progress from school Science to careers like nursing or pharmacy.
Do you approach subjects like Physics or Biology as a collection of formulas and facts? Or do you view the overarching concepts they are built on? The former isn’t ideal for developing focused expertise.
For example, consider an advanced pharmacology class, wherein you have to learn about various drugs and their interactions (or contraindications). Many types of nurse practitioners, including those specializing in pediatrics or mental health, must develop expertise in this subject. Instead of memorizing drug names and functions, you can approach this subject like this:
- Study the mechanisms of action.
- Understand the clinical indications.
- Are there any adverse effects you should know about?
- Apply them to patient scenarios.
This gradual approach helps you go deeper into a subject and eventually claim expertise, not just functional knowledge. As Felician University observes, focused expertise can help you develop a deep understanding of a particular area, fuelling advancement in your studies and career along with personal fulfillment.
3. Peruse Peer-Reviewed Research Papers
Right now at CERN, the world’s most impressive physics lab, experts are busy exploring quantum phenomena at high energy. As part of the ATLAS experiment, we can now know much more about the Higgs boson and quantum entanglement
Scientific American asks questions that any interested student cannot help but be intrigued by: what does quantum mechanics tell us about reality and multiple universes?
Now imagine staying limited to a textbook that only introduces quantum phenomena, very doubtfully, and still claims that these ideas are only on paper.
One of the best ways to progress toward expertise is to delve into these papers: peer-reviewed, well-established journals that introduce new concepts and ask questions you may not hear in the classroom. Don’t be afraid of their apparent complexity, as the purpose isn’t to understand everything at once.
What you need to examine is:
- What the researchers are questioning?
- What data collection methods did they use?
- Do the findings change ideas you have held for a long time?
A Nature feature offers excellent advice on reading papers without getting overwhelmed: starting with discovery and triage, then moving to skimming and deep reading. Even if you don’t get to the deep reading stage with your current study schedule, skimming can still be a good start to pique your interest.
“The goal is to identify the research question, main assumptions, and key findings. I use the paper’s structure to guide my reading, focusing on subsection headings, topic sentences, the introduction and the conclusion.” Shea Andrews, Psychiatry Professor and Researcher.
From Memorization to Focused Expertise: At a Glance
| Learning Stage | What You Do | Goal |
| 1. Recall | Learn and retrieve key facts | Build foundational knowledge |
| 2. Understand | Explain concepts in your own words | Develop conceptual understanding |
| 3. Connect | Link related concepts | Build a knowledge framework |
| 4. Apply | Use knowledge in a new situation | Develop practical understanding |
| 5. Analyze | Compare possibilities and evaluate evidence | Strengthen clinical/scientific reasoning |
| 6. Practice & Reflect | Test yourself, identify gaps, and improve | Develop deeper expertise |
One Step at a Time
Focused expertise won’t come overnight. But starting early can give you an advantage as you move through school, college, and further education.
Some of these activities may seem complicated at first, but many students find that they make them more curious and open-minded. Pursuing expertise is like finding a tribe of people who want to dig deeper, not just accept everything just because someone said so.
FAQs
How long does it take to become an expert in a science subject?
There is no fixed timeline. The time required will depend on the subject’s complexity, your starting knowledge, the amount and quality of practice, and how consistently you study.
How will I know whether I genuinely understand a particular science concept?
Try explaining it without your notes, applying it to a new problem, answering questions about it, or teaching it to someone else. If you can only recognize the information when you explicitly see it, you have likely not mastered it yet.
How can I turn scientific knowledge into practical expertise?
Apply concepts to problems, experiments, case studies, simulations, projects, or real-world scenarios. Application helps bridge the gap between knowing information and using it effectively.
