Video Summary: What Is Problem Solving
Ever wonder why some students ace the SAT's logic puzzles while others struggle? The secret lies in mastering trial and error and algorithm strategies that form the foundation of effective problem solving. Consider how NASA engineers troubleshoot spacecraft malfunctions-they systematically apply different problem-solving approaches, from quick mental shortcuts to detailed step-by-step procedures. What is Problem Solving encompasses these diverse strategies that help us navigate everything from algebra homework to real-world challenges. Watch the full video on JoVE Coach to master this concept with expert-led visuals and step-by-step explanations.

Understanding What is Problem Solving: A Strategic Approach
Trial and error and algorithm represent two fundamental pillars in the problem-solving toolkit that students encounter throughout their academic journey. Problem solving is the cognitive process of finding solutions to difficult or complex issues through systematic approaches. Whether you're tackling AP Chemistry stoichiometry problems or preparing for the MCAT's critical thinking sections, understanding these core strategies becomes essential for academic success.
Trial and Error: Learning Through Systematic Testing
The trial and error and algorithm tutorial begins with understanding how trial and error operates as a foundational learning mechanism. This approach involves systematically testing different solutions until finding one that works effectively. In US high schools, students frequently encounter this method in chemistry labs when determining optimal reaction conditions or in physics experiments when calibrating equipment settings.
Consider how pharmaceutical researchers at companies like Pfizer or Johnson & Johnson develop new medications. They don't immediately know which molecular combinations will produce desired therapeutic effects, so they systematically test thousands of compounds through controlled trials. This mirrors how students might approach complex algebra problems-trying different algebraic manipulations until reaching the correct solution.
Algorithmic Problem Solving: Guaranteed Pathways to Success
Understanding how trial and error and algorithm works reveals algorithms as step-by-step procedures that guarantee solutions when followed correctly. Unlike trial and error's exploratory nature, algorithms provide predetermined pathways to solutions. Students encounter algorithms daily: long division in mathematics, the scientific method in biology, or PEMDAS for order of operations.
The SAT Math section frequently tests algorithmic thinking through multi-step word problems requiring systematic approaches. For instance, compound interest calculations follow specific algorithmic steps that, when executed properly, always yield correct answers. This reliability makes algorithms particularly valuable for standardized test preparation where accuracy is paramount.
Heuristics and Insight: Advanced Problem-Solving Strategies
The trial and error and algorithm concept extends beyond basic approaches to include heuristics-mental shortcuts that simplify complex decisions through pattern recognition. AP Psychology students learn how heuristics help process information efficiently, though sometimes leading to cognitive biases.
Medical students preparing for the USMLE rely heavily on diagnostic heuristics, recognizing symptom patterns to quickly narrow differential diagnoses. Similarly, insight represents those "aha!" moments when solutions suddenly become clear, supported by research showing increased right temporal lobe activity during breakthrough realizations.
Frequently Asked Questions
Problem solving is the systematic process of finding solutions using various approaches like trial and error, algorithms, heuristics, and insight. Understanding these strategies helps you choose the most efficient method for different situations, whether solving AP Calculus problems or tackling real-world challenges. Each strategy has unique advantages-algorithms guarantee accuracy while heuristics save time through mental shortcuts.
The SAT Math section frequently tests both approaches through multi-step problems requiring systematic solutions (algorithms) and questions where testing answer choices works efficiently (trial and error). AP Science exams emphasize algorithmic thinking in laboratory procedures and data analysis. Understanding when to apply each strategy can significantly improve your test-taking efficiency and accuracy.
MCAT success requires mastering all four strategies depending on the question type and time constraints. Use algorithms for stoichiometry calculations and physics formulas where step-by-step accuracy is crucial. Apply heuristics for passage-based questions where pattern recognition speeds comprehension. Save trial and error for elimination strategies when other methods prove time-consuming.
Emergency room physicians at hospitals like Mayo Clinic or Johns Hopkins use systematic diagnostic algorithms for life-threatening conditions while employing heuristics for rapid triage decisions. Pharmacists apply algorithmic thinking when calculating dosages but rely on insight when identifying potential drug interactions. Understanding these applications helps pre-med students appreciate problem solving's clinical relevance.
These problem-solving strategies require no advanced mathematical prerequisites and actually help develop mathematical thinking skills. High school algebra provides sufficient background for understanding algorithmic approaches. The key is recognizing when to apply systematic procedures versus exploratory methods, skills that transfer across all academic subjects.
Create a strategy toolkit by practicing each approach with different problem types from your coursework. Start with algorithm-based problems like chemistry stoichiometry, then progress to heuristic applications in reading comprehension. Time yourself to build efficiency, and keep a problem-solving journal noting which strategies work best for different question types.
Insight involves sudden breakthrough realizations supported by increased brain activity in the right temporal lobe during "aha!" moments. While insight seems spontaneous, you can cultivate it through diverse problem-solving practice, taking breaks when stuck, and exposing yourself to various solution approaches. Many scientific breakthroughs emerge when researchers step away from problems and allow subconscious processing to occur.
Explore decision theory and game theory applications in economics courses, or investigate artificial intelligence problem-solving algorithms in computer science. Psychology students might delve deeper into cognitive biases affecting heuristic reasoning, while pre-med students could study evidence-based medicine approaches that combine multiple problem-solving strategies for optimal patient outcomes.
