EMMANUELLA - Know your tutor
My name is Emmanuella, and I am a Graduate Data Science student with a strong background in teaching, academic support, and data analysis. I have experience working with students at the high school and undergraduate levels, where I provide clear, step-by-step guidance in Mathematics, Statistics, and Computer Science. I focus on breaking down complex concepts into simple, practical explanations to help students build confidence and improve performance. In addition to teaching, I am skilled in Microsoft Excel for data organization, analysis, and reporting, alongside other analytical and technical tools used in data science. I am currently pursuing my graduate degree in Data Science, where I continue to strengthen my quantitative, analytical, and problem-solving skills through hands-on projects and real-world applications.
EMMANUELLA graduated from Babcock University

Programming class overview
My name is Emmanuella, and my teaching methodology is student-centered, structured, and results-driven. I begin by assessing each student’s current level of understanding to identify learning gaps and tailor my approach accordingly. I break down complex concepts into simple, step-by-step explanations, ensuring students fully understand the “why” behind each solution, not just the final answer. I use guided practice, real-world examples, and interactive problem-solving to reinforce learning and build confidence. I encourage students to ask questions freely and think critically, creating a supportive environment where mistakes are treated as part of the learning process. I also incorporate visual aids, practice exercises, and continuous feedback to track progress and adjust teaching strategies when needed. My goal is not only to help students succeed academically but also to develop their independent thinking, problem-solving skills, and long-term confidence in mathematics, statistics, and related subjects.

Computer Science concepts taught by EMMANUELLA
The Tutor and Student reviewed concepts of functions and the average rate of change, applying formulas to real-world data including temperature and percentages. They practiced interpreting positive and negative rates of change and worked through graph-based problems to calculate average rates. The Tutor also introduced the CPA method for problem-solving and offered to provide additional resources.
