Algebra 1

I earned a BS in mathematics (including a lot of algebra) at MIT and a PhD in mathematics at Berkeley. I have used algebra in several small software businesses, including one mathematical software company.

####
Algebra 2

Algebra and geometry are the two main pillars of mathematics. Besides tutoring mathematics, I have used algebra quite extensively in several small software businesses I have run, including one mathematical software company.

My approach to teaching mathematics is to blend problem-solving with a deeper understanding of the content, and to adjust my approach to the needs of each student.

Calculus

I earned a BS in mathematics at MIT and a PhD mathematics (geometry and physics) at Berkeley. As a Research Mathematician at GE R&D, I performed engineering physics simulations in numerous areas. I won a Technical Achievement Award, and published over 2 dozen internal technical reports and four papers in refereed journals.

Basic calculus contains three powerful ideas: taking limits, computing slopes of curved lines, and computing areas under curves. My approach to teaching calculus...

Vocabulary

Vocabulary is an essential ingredient in good English. In my experience, vocabulary is the most important factor limiting verbal scores on SAT reading. A tutor can most effectively improve students' vocabulary by explaining new words as they occur in spoken or written language and in verbal tests. I can recommend vocabulary-building lists, but students can most cost-effectively do this sort of work on their own.

####
Grammar

I bring an "old school" background in grammar, including outlining ideas and diagramming sentences. While students need not learn this material, it helps me to explain subtle differences in meaning among different ways of expressing an idea.

####
Microsoft Excel

I run a small software company, ModelSheet Software, that sells advanced business analysis solutions in Excel. I have built all the models on the website. I have been doing complex analyses in spreadsheets for 20 years.

I earned a BS in math from MIT, a PhD in math from Berkeley, and an MBA in Finance from U Chicago.

####
Geometry

More than any other part of mathematics, geometry combines intuition, computation and rigorous proof. Geometric intuition can help students to see their way through complex problems in other disciplines. I can teach geometry as problem-solving, and at a higher level to the extent that the student is receptive.

I earned a BS in math from MIT and a PhD in mathematics (geometry and physics) at Berkeley. My main field of expertise is Riemannian geometry, of which Euclidian geometry and...

Physics

After earning a PhD in mathematical physics at Berkeley and a BS in math at MIT, I was a research scientist at General Electric R&D, where I built engineering physics simulations in many fields (stress and thermal analysis in glasses, metals and ceramics; optics; acoustics; plasma physics). I won a Technical Achievement Award, published over two dozen internal technical reports and four papers in refereed journals.

At GE R&D I delivered some seminars to staff outside their fields of...

Precalculus

Precalculus combines algebra with limits. Calculus has just two basic concepts: slopes of curved lines, and areas under curves. The rest is computational techniques. I am expert in tutoring these concepts and methods.

I combine teaching students to solve problems with imparting a deeper grasp of the concepts that underlie the procedures for solving problems. I also teach test-wise tips for smart test-taking. I blend these approaches to do what best fits the student’s learning style...

Reading

The most important skill in good reading is to grasp the subtler distinctions between what an author is saying and something he/she is not saying. This skill requires a good understanding of grammar, followed by the ability to extract clear logical meaning from a reading passage. I bring a mathematician's precision to analyzing the logic and smoothness of language. (My formal degrees are in mathematics, physics and finance.)

For thoughtful reading materials, a strong vocabulary is also...

Trigonometry

Trigonometry can seem daunting because of the complexity of the formulas. The solution to this challenge is to develop a deeper geometric understanding of what is going on.

My approach to teaching mathematics is to blend problem-solving with a deeper understanding of the content. Unlike most tutors, I know how to teach mathematics as a science, not just as a way to solve problems. Please see my overall profile for information about my tutoring qualifications.

English

I bring an "old school" background in grammar, including outlining ideas and diagramming sentences. While students need not learn this material, it helps me to explain subtle differences in meaning among different ways of expressing an idea.

The most effective ways for students to improve English skills are to practice, to hear and read good English, and to learn formal rules. Getting explanations of subtler points from a tutor can help substantially.

English grammar is...

Economics

I earned an MBA in Finance at UChicago, and I took a minor in economics as part of my BS at MIT. I replaced many of the elementary courses in economics with advanced electives in both universities. I have practical experience applying microeconomic concepts to numerous businesses, as a consultant with McKinsey & Co. and with other companies large and small.

My approach to tutoring economics is to combine problem-solving skills with a rich understanding of the foundations.

I have been general manager or president of several small companies where I dealt with financial analysis of the business.

I currently run a small company that markets advanced financial spreadsheet analyses...

####
SAT Reading

Reading is the most complicated skill on the SAT. The SAT tests comprehension of subtle distinctions in meaning and ability to inference shades of meaning from explicit information in the text passages. I teach important test-taking tips for different types of SAT reading questions.

The most common sources of errors on SAT reading are: (1) the student gets the right general idea, but fails to comprehend the secondary distinctions for which the SAT tests; and (2) limited vocabulary can...

SAT Writing

SAT Writing includes grammar, organization, paragraph and sentence structure, and writing in an interesting style.

I teach both good writing practice and how to get a high score on SAT Writing. While these two topics overlap substantially, they differ in significant ways.

The College Board’s business model is based on inexpensive automated scoring. While multiple choice testing of grammar fits this model, evaluating essays does not. This situation has major consequences...
