I am a PhD chemist with more than 30 years of experience. I taught chemistry at Augsburg College, Anne Arundel Community College, Northern Virginia Community College and ECPI University. I tutored chemistry students at the US Naval Academy. I completed college courses in general physics, electronics, optics, and laser physics. I have active DoD Top Secret Security Clearance. I have a PhD & an MS in Analytical Chemistry from University of New Mexico and a BA in Chemistry from Augsburg College. I also tutor math, algebra, and SAT & ACT exams.

Approved subjects are in bold.

Approved subjects

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

ACT English

I have passed college English courses and a technical writing course. I also passed an American Literature course in college. I have 52 scientific publications.

ACT Math

I have completed high school math classes of algebra, advanced algebra, plane & solid geometry, and trigonometry with As in each course. I had calculus and advanced calculus for a total of 4 quarters in college. I scored in the 98% on the ACT Math test when I took it in 1965. I have earned a PhD. in chemistry. I have taken short courses on statistical design of experiments and statistics for scientists.

ACT Reading

I passed college courses in American Literature and Greek Mythology. I enjoy reading and I read several books each year.

ACT Science

ACT Science covers all areas of science (Biology, Chemistry, Physics, , Earth Science, Geology and Astronomy).

I will provide an overview of science and seek to determine which areas the individual student is having difficulty understanding and comprehending. Often students have difficulty with word problems in remembering the appropriate equations to solve the problem. Sometimes definitions of terms are needed that present difficulty. ACT Test taking is an art. If the student is pressed for time, they should take educated guesses if a few of the answers can be eliminated. There is helpful information on ACT Science on the internet that I will help the student locate for their studying for the exam.

Algebra 1

I completed algebra and advanced algebra in high school and calculus and advanced calculus in college. In 1965 I scored 729 in math on the SAT test. Algebra is used a lot in chemistry and physics.

Chemistry

General chemistry provides the foundation for further study in chemistry and should provide an understanding of the value of chemistry to the informed citizen. Students often have to learn the meaning of terms and have difficulty with word problems. Sometimes math has to be learned along with the chemistry. I will use the student's textbook supplemented with material I can supply in the tutoring sessions.

Organic Chemistry

Organic Chemistry is a broad subject dealing with the chemistry of carbon and hydrogen compounds with oxygen, sulfur, nitrogen and halogens. Organic chemistry provides the foundation for studying biochemistry. Laboratory work is used to develop synthetic, separation, and identification techniques. Polymer chemistry is an advanced branch of organic chemistry. The student learns about reaction mechanism and organic nomenclature. Organic chemistry is generally required for admission to medical school.

I have passed the following courses in Organic Chemistry:
Augsburg College Chem 51 Organic Chemistry, 6 QTR, Fall 1967
Augsburg College Chem 52 Organic Chemistry, 6 QTR, Winter 1968
Augsburg College Chem 63 Advanced Organic Chemistry, 5 QTR, Spring 1969
Augsburg College Chem 81 Advanced Analytical Chemistry, 5 QTR, Fall 1969
University of New Mexico Chem 504 Theoretical Organic Chemistry, 3 SEM, Fall 1970
University of New Mexico Chem 505 Theoretical Organic Chemistry, 3 SEM, Spring 1971
University of New Mexico Chem 420 Advanced Organic Chemistry, 3 SEM, Spring 1971

Physical Science

Physical Science provides the basic information in chemistry, physics, and engineering to students. I prefer to follow their textbook and provide useful explanations and assistance with homework problems and the approach to problems solving.
Often math skills are involved in the problem solving.

Physics

Physics deals with electronics, optics, magnetism, gravity, motors, radio, television and various forms of work. Relativity, particle physics, and many more areas that are the basis for engineering are also included in physics. I will assist the student in understanding terminology, and approaches to solve word problems. Good skills in mathematics help in being successful in physics. I have completed three college courses in general physics, electronics, optics, laser physics and quantum mechanics.

Prealgebra

I have completed High School math through statistics and trigonometry, as well as four courses in college calculus. Pre-algebra is kind of math used to get students think in the abstract.

PSAT

The PSAT or Preliminary SAT also serves as the National Merit Scholarship Qualifying Test. It covers: Critical Reading Skills; Math Problem Solving Skills; and Writing Skills. I can cover all these areas. The math skills are what concern most students. Good academic training in all high school classes is the best first approach to preparing for the PSAT.

SAT Math

In 1965 I scored 729 on the SAT Math. I use math in my chemical research and teaching of chemistry to college students. I scored A's in all my high school math courses. I passed calculus and advance calculus in college. I earned a PhD in analytical chemistry. I enjoy tutoring to assist students with learning.

SAT Reading

I passed college courses in American Literature and Greek Mythology. I enjoy reading a variety of books. I read several books each year. I have studied the College Board guidelines for the SAT exam.

SAT Writing

I passed College English courses and a technical writing course. I have 52 scientific publications. I enjoy writing letters. I have studied the College Board guidelines for the SAT Writing Exam.

TAKS

The Texas Assessment of Knowledge and Skills in Mathematics Exit Level Exam features test objectives. The test objectives are: Numbers and Operations; Equations and Inequalities; Functions; Geometry and Spatial Sense; Measurement; Data Analysis and Probability; and Problems Solving. I have downloaded the Mathematics Studyguide with practice tests that I will use to assist the student in learning the test objectives. I also downloaded a previous version of the TAKS Mathematics Exit Level exam that I will use to assess the students preparation and progress during the tutoring lessons. I made a grade of A in my high school math courses in algebra, advanced algebra, plane and solid geometry, and trigonometry.

I have more experience with in person tutoring than on-line.  It is harder to determine if you have the students attention on-line.  Using a computer camera would help this situation.  Scheduling may be easier on-line since once does not have to travel or select a public location for the lesson.  I have used libraries, Panera Bread and Starbucks when I do not go to the students... read more

The atomic radius increases as one goes down a group in the periodic table because more electrons are around the atom and more neutons and protons are present. As one goes across a period the atomic radius decreases because more protons are in the atoms as one goes across the period and the electrons...
