Haley Shea
Neuroscience Tutor • +32 Subjects
Haley graduated from the University of North Georgia with two bachelor's degrees in English Writing & Publication and Interdisciplinary Studies (Mathematics/Technology, Social Science, and Humanities concentrations), and an associate's degree in Psychological Science (2020). Previously, she completed an associate's in Communication, Film & Digital Media Studies (2016). While at UNG, she worked as a Writing Center Peer Consultant, Supplemental Instruction Facilitator, English Department Student Administrative Assistant, Writing Fellow, and Ambassador for the Center for Undergraduate Research & Creative Activities (in addition to programming stimulus displays for EEG experiments in the neuroscience lab). Her major fields of study are supplemented by three minors: Linguistics, Psychology, and Studies of English Language Learning. Combined, this background enables a flexible tutoring approach that can be customized to meet the needs of both additional-language learners and individuals facing cognitive challenges. Haley Shea is currently pursuing graduate-level education in cognitive science, conducting neuroscientific laboratory research in psycholinguistics and brain-computer interface, and training for a career in human-computer interaction. During college, her top subjects were Advanced English Grammar and Linguistics. There, she was known for her passionate leadership of study sessions for sentence-diagramming, which inspired her laboratory research. An active community member, she was Vice President of the English Honor Society chapter and led the UNG Writers Guild for two years, helping students write and gather valuable feedback from one another, enabling them to better proofread and edit their work for future publications. Many of those writers saw their work in print through UNG's award-winning student literary magazine, for which Haley Shea served as an editor for several years. Other campus engagements included running the community book drive for over two years and founding an all-student improv troupe which went on to perform and compete in tournaments around the state and region. While acting helped her become comfortable on-stage, Haley Shea also greatly benefited from her time as a member of the speech and debate team, placing first in statewide debate and slam poetry competitions over the years. Her favorite topic of both debate and poetry is that of human innovation and interaction with emerging technology, especially in relation to ethical policies on artificial intelligence. Captivated by syntax in both spoken language and computer code, she is fascinated with recent developments in language-based software and hopes to contribute to the field of computational psycholinguistics while earning her PhD. After graduating, Haley Shea knew she wanted to keep supporting other students toward their goals. A scholarship student herself, she always loves any chance to help individuals express their strengths and unique personal histories in ways that will help further their goals. To this end, she continues to mentor applicants for nationally competitive scholarships and other student support opportunities, such as the McNair Scholars Program and Goldwater STEM Scholarship, two major awards which made an immense difference toward the funding of her bachelor's education when she was named an official recipient in 2019, in honor of her interdisciplinary research and commitment to fostering student success on campus. She finds joy in any opportunity to uplift other students--especially women in STEM, individuals facing disabilities, or anyone who seeks to improve their command of the English language. In sharing her passions with her students, she helps them break out of "analysis paralysis" into a fun, personalized routine that helps foster positive associations with the topic of study and strong metacognitive skills that lead to improved performance over time. Special Topic Announcement: Students of English writing, grammar, comprehension, et cetera may enjoy developing their meta-linguistic awareness through Sentence Diagramming. Ask during booking to learn more about how you can become a grammar wiz through one-on-one classes in Sentence Diagramming taught by Haley Shea.

Frequently Asked Questions
Students often find object-oriented programming principles—particularly inheritance, polymorphism, and encapsulation—challenging to grasp beyond memorizing definitions. Exception handling and understanding stack traces is another major pain point; many students panic when they see a NullPointerException or ClassNotFoundException without knowing how to read the error message. Additionally, working with collections (ArrayLists, HashMaps, etc.) and understanding when to use each data structure trips up many learners, as does the difference between pass-by-value and pass-by-reference behavior in Java.
A tutor can teach you systematic debugging techniques like using print statements strategically, leveraging the Java debugger to set breakpoints and step through code, and most importantly, how to read and interpret error messages rather than just seeing them as obstacles. They'll show you how to isolate problems by testing small code segments in isolation, use the call stack to trace where errors originate, and develop the habit of thinking through your logic before running code. This approach transforms debugging from frustrating guesswork into a methodical problem-solving skill.
Syntax is the rules of how to write Java code—knowing that you use curly braces, semicolons, and proper method declarations. Algorithmic thinking is understanding the logic of *what* your code should do and *how* to solve a problem step-by-step, which is language-independent. Many students can write syntactically correct Java but struggle to design an algorithm to solve a problem. A tutor helps you develop algorithmic thinking by working through problems like sorting, searching, and data manipulation before you even write code, then translating that logic into Java syntax.
Rather than memorizing the differences between ArrayList, LinkedList, HashMap, and HashSet, it's more effective to understand the underlying concepts: when you need fast access by index (ArrayList), when you need efficient insertion/deletion (LinkedList), or when you need key-value pairs (HashMap). A tutor can guide you through building simple projects that naturally require different data structures, so you learn *why* you'd choose each one through hands-on experience. This contextual learning sticks much better than abstract comparisons.
OOP is best learned by designing and building actual objects, not by reading definitions of inheritance or polymorphism. A tutor can guide you through creating class hierarchies (like Animal → Dog → GoldenRetriever) and seeing how polymorphism lets you write flexible code, or designing interfaces to solve real problems. Working through code reviews where a tutor explains why a particular OOP design is better than another helps cement these concepts. The key is moving from "I can define encapsulation" to "I can design classes that are maintainable and extensible."
Building real projects—whether a simple to-do list application, a game, or a data analysis tool—forces you to integrate multiple concepts (classes, loops, collections, file I/O, exception handling) in ways that isolated exercises don't. Projects also expose you to practical challenges like managing state, handling edge cases, and writing readable code. A tutor can help you scope projects appropriately for your level, guide you through design decisions, and provide code review feedback that teaches you why certain approaches are better than others.
Absolutely. If you're interested in web development, you'd focus on frameworks like Spring and databases; for data science, you'd emphasize working with libraries and handling large datasets; for game development, you'd explore game engines and graphics libraries. While core Java fundamentals (OOP, collections, exception handling) apply everywhere, a tutor familiar with your specific goals can prioritize which advanced topics matter most and show you real examples in your area of interest. This keeps learning focused and motivating rather than abstract.
Beyond knowing Java syntax and libraries, an effective Java tutor should be able to explain *why* code works the way it does, not just show you examples. They should have real-world coding experience so they understand practical challenges, be comfortable reviewing your code and explaining design trade-offs, and most importantly, be able to meet you at your level—whether you're struggling with loops or designing complex class hierarchies. They should also help you develop debugging intuition and problem-solving approaches that transfer to new situations, rather than just solving problems for you.
