## Very knowledgeable and patient!

Sandra, 40 lessons with JohnBoth of my kids have been tutored by John for Alg 2 and look forward to their sessions. He provides positive feedback and gentle reminders. They aren't afraid to ask questions or try to solve a problem even if they aren't sure of themselves. Great teacher!

As a tutor my goal is to have a positive impact on the lives of the students with whom I work. No magic wand will put the power of learning solely in my hands, but students that come to me prepared to work will find me a valuable resource and an enthusiastic ally.

I have been working in the Austin area over 20 years, and with Wyzant since 2008. I have a BS in math from UT-Austin, including 50+ combined credit hours in physics, chemistry, and statistics. I've worked in the UT math department,...

Statistics
#### Statistics

The key to first-year statistics is keeping the big picture in mind, both figuratively and literally. From describing distributions to calculating probabilities, the descriptions and formulas used in statistics are strongly geometrically-based, and it is an understanding of this geometric foundation that can guide students through multi-step calculations, without losing sight of the end goal.
Graphs are a great tool for visualizing probabilities studied in statistics, and many teachers require students to include graphs in their work. It is my experience that until a student can consistently generate the correct graphs, in determining probabilities, they will struggle using the associated formulas, too, but once they understand how to correlate probabilities to their corresponding graphs, they can easily apply statistical formulas correctly, and easily tweak the formulas correctly as they move through strongly-related sections of the course, such as those covering normal distributions, t-distributions, confidence intervals, and hypothesis testing.
Using statistical formulas correctly also entails understanding the Central Limit Theorem, arguably the most important topic of the class, and its implications. With this understanding, one can easily work through the interrelated topics listed above.
My goal as a statistics tutor is to help students understand the graphical foundations of statistics, correlate graphs to their corresponding formulas, understand the Central Limit Theorem, and understand how many of the topics covered in the course are interrelated, so as to not have to reinvent the wheel, so to speak, as they move from topic to topic.

Algebra 1,
#### Algebra 1

Algebra is not a subject many students get excited about right off the bat. However, I find that students' interest in the subject grows as they find they can master topics they once found merely confusing, and strong algebra skills are an imperative to success in higher level math and science classes, and on standardized tests such as the ACT and SAT, so I always encourage students to do their best to master algebra, even when it gets tedious.
As an algebra 1 tutor my goal is to help students create a mental framework for the various topics they encounter in class, and to discern between methodologies that are topic specific, such as to linear, or quadratic, functions, and those that can be applied more generally, such as transformations, and properties of inverse functions. I strongly encourage students to adopt a best practices model for their work, and to not work in a minimalist fashion. A math journal, reflecting the various aspects of topics discussed in class, is a great way of building up an orderly mental framework of the topics covered in this and other classes, and will serve as a great reference within other math classes that require the methodologies covered in algebra.

I strongly encourage students to adopt a best practices model for their work, to not work in a minimalist fashion. And, lastly, I encourage students to keep a math journal reflecting the various aspects of topics discussed in the class. The only way to succeed in algebra is to have an ordered understanding of the many topics covered, and getting those topics down in an orderly written form, in their own words, is a great way of building that mental framework.

Calculus,
#### Calculus

Many of the difficulties students encounter in first-year calculus stem from gaps in their understanding of topics covered in algebra and precalculus. My method for teaching calculus is to relate the new ideas discussed in calculus to topics covered in previous classes. In this manner, any gaps or forgotten knowledge will necessarily be reviewed in the process, too.
For students in college or high school AP classes the pace of the course can also be a challenge, but as part of helping students through particular problems, my goal is to help them relate ideas from multiple sections together, and to develop a conceptual understanding of the underlying principles at work including, for example, the graphical foundations of the formulas used in calculus, and how these principles do, and do not, generalize.
Having studied advanced calculus, and applying it in upper division physics classes, I can help students develop a deeper understanding of the material, making the formulas more intuitive, easier to remember, and easier to apply correctly.

Chemistry,
#### Chemistry

Doing well in general chemistry is largely about knowing how to use the periodic table. However, early on there are other aspects of the class that depend solely on rote memorization, such as the formulas and charges of the common polyatomic ions, and basic formulas for things such as pH and molarity. A little math is involved when it comes to stoichiometry, but generally if a student can keep the big picture in mind, the mathematical steps are pretty simple. As a tutor, I strive to keep these different aspects of the class clear, and to help students keep the underlying picture in mind when working through different types of problems requiring calculations.
College and AP chemistry classes will contain more complicated, multi-step problems, often related to energy considerations, but a deeper understanding of the underlying general principles governing a process can help make sense of the ordering of the required steps needed to solve a complicated problem, and as I work through specific exercises with students, I will also emphasize these principles and how they apply.

Geometry,
#### Geometry

Geometry is one of the classes where I have seen some dramatic turnarounds in student performance. My experience has been that, due to the less formulaic nature of the class students get used to in arithmetic and algebra, they are not always sure what is expected of them in geometry. As a tutor, my goal is to help students understand what is expected of them in, for example, presenting a proof, as well as fill in any gaps in the required algebra they may have forgotten. I will instruct students to focus on the various postulates, theorems, and definitions required for success in geometry. These are the building blocks of proofs, as well as the justifications used for simpler computational type problems.

Physics,
#### Physics

Physics is going to be a challenge for nearly every student the first time through. Ideally, I like to meet with students early in their studies and help them understand what I consider the most important topic for them to master first, vectors. This understanding is crucial to success in the class, but some students may not have the prerequisite math (precalculus), and/or the importance of vectors may be underemphasized by their teachers.
Beyond that I like to present strict algorithmic methods students can consistently apply when solving general classes of problems, as for kinematics, Newton's Laws, conservation of momentum, work and energy, and rotational dynamics, etc. Having studied calculus-based general physics, upper-division Newtonian physics, classical electrodynamics, and waves and optics, as well as having tutored high school and college physics for several years, I can help students keep the big picture in mind as they determine which equations, and how to use them, to solve easy or complicated physics problems.

Prealgebra,
#### Prealgebra

Strictly speaking, prealgebra refers to the arithmetic required for success in algebra, such as how to work with positive and negative numbers, how to apply the arithmetic operations (+, -, *, and /) to fractions, properties of exponents, and the correct "order of operations" to apply to expressions containing multiple arithmetic symbols. However, there are other aspects of prealgebra that students will do well to focus on, too: those of mathematical definitions and properties of numbers and number systems, that are used extensively in algebra, such as the commutative and associative properties of addition and multiplication, the distributive property, the sets of: natural, whole, integer, rational, irrational, and real numbers, and many others.
As a prealgebra tutor, I don't want to see students get bogged down in this abstract aspect of the class. I want students to be able to use them in a second-nature sort of way. But transitioning from arithmetic to algebra is abstract in nature, and it is imperative, if students are to understand what they are reading in an algebra textbook, or the instructions on a test or homework, that they have a proper understanding of the vocabulary used, and the general properties of numbers needed to solve algebra problems. Furthermore, it is exactly these types of definitions and properties that are most important in a class like geometry, where a student has to justify each step of their work with a definition, postulate, or theorem. Though I help students work through computational problems in prealgebra, I also remind them of the properties and theorems used to justify the steps involved, in the hopes they will be able to apply these definitions and properties in ever more sophisticated ways in their ongoing study of mathematics.

Precalculus,
#### Precalculus

Precalculus is a class where many students will start to have some issues, even if they have been doing well in earlier math classes. I suspect this difficulty arises for two main reasons: one is the novelty of new functions encountered, such as the trigonometric functions, and two, because this class draws heavily upon properties of functions studied in algebra, which may have been forgotten. As a pre-calculus tutor, my goal is to remind students of these properties, where applicable, and to help ease the transition into trigonometry by breaking down the various aspects of the trigonometric functions into those that must simply be memorized, and those that are interrelated. I will also help them minimize the amount of rote memorization required by exploiting the interconnections between many of the topics covered.

SAT Math,
#### SAT Math

SAT problems can sometimes get a little tricky, as they do not always match the type of problems seen in textbooks. This is largely by design. The easiest problems are designed to be similar to what students have seen before, to test for baseline knowledge, and then more challenging problems are designed to test students' abilities to think on their feet, so to speak. (Think on their seats?) None the less, preparing specifically for the SAT will give students exposure to a broader range of question types, and almost always pay dividends.
With a background in college mathematics, and many years of tutoring, including SAT preparation, I can give students insights into the types of questions to expect, as well as help with core material they may have forgotten, or not yet been exposed to.

Differential Equations,
#### Differential Equations

Differential Equations is truly one of my favorite subjects to tutor. Although I enjoy tutoring a wide range of math classes, I was never really excited about math until I enrolled in this class. While at UT-Austin, I made A's in Differential Equations, Vector Calculus, Real Analysis, and Vector and Tensor Analysis. I also made A's in the physics classes that required the techniques taught within them: Wave Motion and Optics, Classical Dynamics, Classical Electrodynamics, and Kinematic Astronomy. One caveat: many DE classes now include MatLab exercises. I am not familiar with MatLab.

Discrete Math,
#### Discrete Math

As an introduction to counting methods (combinatorics) and proofs, Discrete Math is one of the first proofs courses I took at UT-Austin. I made an A in the class as well as in many other related upper division math classes, including Linear Algebra, Probability, Real Analysis and Topology. Although I have seen variability in the difficulty of this class, based on the aims of the different teachers teaching them, I have yet to need to turn anyone away and feel very comfortable with the material.

Finite Math,
#### Finite Math

Finite math is a survey of several topics in math from arithmetic to precalculus, as well as an introduction to various math disciplines not covered in the core curriculum. My study of math spans most, if not all, of the topics covered in this class, and also shows that I can quickly adapt to any unfamiliar topics covered at these levels. While working at Austin Community College, I also had direct experience working with students taking Finite Math.

These are the building blocks of proofs, as well as the justifications used for simpler computational type problems.

Linear Algebra,
#### Linear Algebra

Linear algebra is both a computational and a proofs course. However, different instructors will often focus on different aspects of the course, so there is a fair amount of variability among individual courses. As a math major, I have studied a wide range of mathematics and am well-suited for tutoring linear algebra, but proofs cannot always be quickly generated on the fly. When possible, I ask students to let me spend a day or so on the material before our session, in order that the session itself may go more smoothly. For much of the simpler material, such as matrix or vector operations, being able to brainstorm on the material beforehand may not be of much importance, but it doesn't hurt.

Probability,
#### Probability

I studied probability as part of my degree plan at UT, and use it extensively in statistics as well. The study of probability is largely about 1. counting methods, often studied in discrete math classes, and 2. learning the various types of distributions commonly used in modeling data: exponential, normal, gamma, uniform, etc,, including the important aspects of each type of distribution, such as mean, standard deviation, memorylessness, etc. Often sophisticated calculus techniques are required as well. As a graduate in math from UT, I am well-acquainted with these aspects of the class.

It is my experience that until a student can consistently generate the correct graphs, in determining probabilities, they will struggle using the associated formulas, too, but once they understand how to correlate probabilities to their corresponding graphs, they can easily apply statistical formulas correctly, and easily tweak the formulas correctly as they move through strongly-related sections of the course, such as those covering normal distributions, t-distributions, confidence intervals, and hypothesis testing.
Using statistical formulas correctly also entails understanding the Central Limit Theorem, arguably the most important topic of the class, and its implications. With this understanding, one can easily work through the interrelated topics listed above.
My goal as a statistics tutor is to help students understand the graphical foundations of statistics, correlate graphs to their corresponding formulas, understand the Central Limit Theorem, and understand how many of the topics covered in the course are interrelated, so as to not have to reinvent the wheel, so to speak, as they move from topic to topic.

## Great instruction

Last minute request for AP Physics help. John did a great job clarifying concepts and helping me understand. He helped me feel confident when taking my final this term.

Luke, 1 lesson with JohnTutor responded:Thanks Luke! Sounds like you feel pretty good about the exam. Glad to hear it. Take care.

## great teacher

He explains my son very patiently !! We were having hard time finding a tutor we work with me with son patiently, explain each and every step by step ! We are glad we find Mr. John !!!

## A Great, Well-Prepared Tutor

John taught me a lot. I liked the fact that I could ask him any question, and he always provided an answer that was satisfactory. What's more, he could answer each question to such a deep extent. He saw connections between concepts in Calculus that I never would've even thought of. And even though there may be a lot to explain, he definitely does a very good job with it! I would definitely recommend him as a tutor.

## Excellent Algebra tutor for teens

John did an intro session with our teen son via zoom and he was extremely patient. Working with teen boys is a complete skill-set of it's own. Our son really liked John is very open to weekly sessions with him now - he sees the value in the additional help and support. Thank you, John!

## confidence boost!!! very patient, helped through probelms

I wasn’t confident at all in probability distributions and density functions, but john was able to help me. He made sure that we didn’t proceed with a problem till i full understood what was happening. He was very patient and most importantly open to the questions I had. As a student, some feel intimidated to ask questions we think the question might come as dumb, but John created an open and safe space to ask questions. Will definitely be coming back to john with any concepts or questions I need help in within stats!
