About David

Hello, just call me “Mr. Mac.”

Because of my varied background in engineering mathematics (College Algebra, Trigonometry, Pre-Calculus, and Calculus), university physics and chemistry, and a BA in English and Journalism in Education, I have enjoyed teaching and tutoring in related subject areas for both high school and college students.

•My best success in teaching and tutoring, particularly in mathematics, is to develop patterns from within the immediate topic, to go over text book examples and ask you, the student, if this makes sense, and then to proceed to the related assignment.
•I really enjoy presenting related subject matter with the goal for you, the student, toward future success in assignments and tests.
•Because I have taught in classroom settings and in tutoring venues, I do have documented compliments from students, in addition to an endorsement from my tutoring-site manager.
•The goal in tutoring in any subject matter is to re-enforce to the student the daily need to practice, with the idea that “success breeds success.”
•As an example, in my first several weeks of Plane Geometry in high school, I had real difficulty grasping these new concepts in geometric relationships, i.e. congruence and geometric proofs. But my father secured tutoring services for me which brought me up from a “D”, first quarter, to a “B” second quarter, and thus, gave me that “head-start” needed in my pre-engineering high school curriculum.
•I have tutored my own daughter in home-schooling through each of these math disciplines successfully, in addition to tutoring adults in likewise related college-level classes.

Hoping this gives you a “thumb-nail” sketch of my sincere intent to tutor any student needing that critical, timely personal assistance in achieving daily success in study habits relating to mathematics, particularly Algebra I, Algebra II, Plane Geometry, Solid Geometry, Trigonometry, and Pre-Calculus.

David replied on 12/4/2014

Thank you!
I was so impressed by your very kind and gracious compliments regarding my work with your son: it has always been an easy task, because he is so motivated intellectually in English language arts (poetry and essay-writing), and with his interesting, high-achieving projects. Your son is a high-achieving, gifted student, so, as his tutor in English language arts and physics, it is my privilege to tutor him via the WyzAnt Online Tutoring "Class-room". Thank you again for allowing me that special privilege!

"Great Tutor, Very Knowledgeable"

"Very knowledgeable about geometry."

- Taylor, Wichita, KS on 4/19/13
David replied on 5/3/2013

Thank you, Heidi! It would not have been possible if your daughter had not been such an attentive, diligent and gifted student of Geometry. [I have been remiss in not thanking you here: your compliment is certainly very helpful advertising for my Wyzant Tutoring qualifications. I am glad to know she enjoys my Geometry tutoring presentations with her, and hopefully she will secure that “A” in Geometry as her goal achieved this semester!]
Thank you once again.

Test Preparation:
ACT English,
ACT Math,
ACT Science,
SAT Reading, TOEFL
Special Needs:
Bodybuilding, Chess,

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

To prepare for the ACT English Test would require willingness to practice grammatical structure of sentences, recognition of vocabulary and proper usage, and recognizing homonyms in order to ensure correct meaning and spelling, for starters. I would be glad to assist any student willing to work with available resources, such as an SAT English Test preparatory manual, since that would be a confidence builder that would ensure success if a disciplined effort to prepare were made, in addition to getting a good night's sleep before the Test!

ACT Math

Having taken both the ACT college-entrance exams, and the more specialized "afternoon" Advanced Math testing, I am well-acquainted with the rigors of college-entrance placement requirements, and am ready assist any student via tutoring in ACT Math with regard to Algebra I, Algebra II, Plane and Solid Geometry, and Trigonometry.

ACT Science

Since Science addresses the why's and wherefore's of the physical world around us, it requires the reading and interpreting of data, and then it is always a careful process involving logical and empirical conclusions based on the evidence, whether it be through the scientific disciplines of Physics, Chemistry, Biology, Geology, etc. Hence, in the ACT Science preparations, it is always helpful to address all high-school physical sciences as good preparation.

Adobe Photoshop

Adobe Photoshop is a premier digital photography software package that lends itself well to amateur as well as professional digital photography. Because of its extensive use in photography classrooms, both high-school and college, it is a proven product that allows the student to apply its many facets and applications with as much artistry and attention to detail as needed or desired. Because of my interest in digital photography, I have successfully completed an accredited "Photoshop Elements101" university class in which many of the amazing features of Adobe Photoshop Elements were addressed, so would be glad to work with any student needing tutoring in Photoshop Elements (5.0) basics.

Algebra 1

I have enjoyed teaching Algebra I for more than 15 years in a classroom format and am quite well-acquainted with its content and challenges.

Algebra 2

Because Algebra II requires a good understanding and confident application of Algebra I skill sets, it is very helpful to review Algebra I prior to studying Algebra II. Algebra II is a challenging continuation of Algebra I, with the factoring of quadratics advancing to include factoring of cubic equations; also, introducing the concept of logarithms, with both common and natural logs; solving of linear equations, using the matrix and Cramer's Rule, and presenting arithmetic / geometric series, to list some of the more advanced topics of Algebra II. However, it is all very manageable with a day-to-day regimen of practice (doing your homework), and getting help when needed, from your teacher or a tutor.

American History

American History is the historical panorama and chronological study of the development of the USA, from its Puritan settlements on the shores of the Atlantic Ocean, through its growth and development as its own nation apart from Great Britain, with the creation of its Constitution by our Founding Fathers, and the pages of its history written as it expanded from the thirteen original colonies to its modern-day fifty states, punctuated by the great wars fought to preserve the functions and purposes of its citizens. It is important that each student of the secondary school systems of the USA be given a clear opportunity to study and appreciate American history, and to learn and appreciate the safe-guards of American liberties, fought and won, and secured by the US Armed Forces so "that government of the people, by the people, for the people, shall not perish from the earth." (Abraham Lincoln, Gettysburg Address).


The Armed Services Vocational Aptitude Test (ASVAB) is designed to test on the basics of practical mathematics, including operations with decimals, fractions, percents, and related word problems; the basics of algebra and geometry, logic of mathematics, etc. Further, the ASVAB includes reading comprehension, vocabulary (spelling and definitions), reasoning and logic of multiple-choice responses, and practice to achieve success in a testing environment.

The ASVAB essentially covers a basic, working knowledge of arithmetic, algebra and geometry, and also a successful high-school graduate level of English language arts, including logic and reading comprehension. Because my BS in English/Journalism, and 2.5 years in electrical engineering studies, including physics and chemistry, qualifies me to tutor for ASVAB preparation, I would be glad to tutor any aspiring candidate for enlistment in the US Armed Services to achieve a successful ASVAB outcome.

Bible Studies

In tutoring any student requesting assistance in Bible Study, my approach would be to first determine the goal of the student. and then proceed with Bible Study materials and resources. Because I have enjoyed Bible Study for years in the context of Christian fellowship, I have learned some excellent study tools and Bible Study formats, using a good Bible concordance for research and cross-referencing, and approaches to Bible Study such as Topical, or, Book Survey w/ Chapter Analysis, Verse and/ Bible Vocabulary Word studies, all of which provide excellent preparation for group discussion and application.

My basic belief and study of the Bible is based on reliance on it as God's Holy Word, revealing His Son through its pages, from Genesis, Beginnings, through the Book of The Revelation. I believe its 66 Books have one Supreme Author who breathed the plenary inspiration of its 66 books through its 40 men of God who meticulously recorded the inspired record. As one whose life was dramatically saved by the Lord Jesus Christ, aka The Living Word, I enjoy daily Bible meditation in its pages, enjoy listening to Christian radio speakers, and have attended Sunday School Bible Studies for years. In fact, Bible Book Surveys and Chapter Analysis, Bible Vocabulary-Word Studies are several means of enriched Bible Study that I have enjoyed through the years. I would therefore consider it a privilege to assist anyone requesting tutoring in Bible Studies.


Calculus has two side-by-side axioms: "Use it or lose it", and, from East LA Master Teacher Jaime Escalante, Calculus Instructor/Author: [See the movie, "Stand and Deliver" circa 1988] who used to tell his students via a sign at the front of the classroom: "Calculus can not be made easy: it already is!" Also, recognize that Algebra skill sets are as important in Calculus as Arithmetic is to Algebra. The challenge for the student, through much practice of daily assignments, from the start, is to practice, practice, practice, and be sure to get help from your teacher or tutor when you first have any difficulty. Better yet, see if Prof Escalante has written a Calculus manual on "How to Make Calculus Easy".


Chemistry is the science dealing with the atomic and molecular building blocks of the physical universe. It is a rigorous academic discipline involving much reading in chemistry texts, and also from the empirical value of direct observation in the chemistry lab, with directed experiments by the instructor. Its inherent value allows the student to appreciate the production of manufactured products. How do we produce the practical goods around us, i.e. clothing, furniture, including plastics to automotives/cars, and the never-ending supply of manufactured products? The study of chemistry reveals most of the answers therein. I enjoyed the study of chemistry both at the high-school and university levels, so would be able and glad to tutor any student needing help with the challenges of studying chemistry.


My credentials as a Chess tutor include a genuine appreciation of the genius of the game of Chess. Because of my interest and love of the game, I co-sponsored a Chess Club at the Middle School level for at least one year, qualifying one student to pursue a city-wide competition here in Wichita. Beyond that, I can only share the following observations, with the added, "Practice, practice, practice, to develop a refined game!"

Chess is truly a classic example of a board game worthy of everybody's attention: it places any contenders for the "crown" of the conquering king and his army, including the all-powerful queen, in a studied match requiring a thorough knowledge of the legal moves of each piece, and basic strategies, if not standard and even historical. It is a game that has many terms and moves that have segued into the cultural landscape, such as "check-mate", being a "pawn" in a social struggle, making it worthy of at least a passing familiarity, such that the novice can at least appreciate the possibilities of grand masters playing for a world championship, or, pitting their mastery against that of a chess-programmed super computer. I learned to enjoy chess during my high-school and college years, and have successfully passed on the love and challenges of chess to my son, who can play an excellent game after "warming up" with a game or two!

I can tutor chess fundamentals, and point the interested student to great chess instruction by gifted chess players, who enjoyed writing chess-instruction texts with the ultimate goal of, How to Win Your Chess Game!


The Classics as a generic reference to the greatest enduring literature of Western Civilization, are most generally confined in scope to American and English literature, although ancient Greek, i.e. Homer’s Odyssey, its Roman equivalent, the Iliad, and Russian classics (Tolstoy’s War and Peace; Dostoevsky’s Crime and Punishment) are also important components, primarily from the 19th Century and continuing into the 20th. Because the soul of a nation is embodied in its literature, it is therefore of great value to study its most definitive literature, its classics.
British Literature Classics would most definitely include Beowulf, emerging from ancient British literature, and Chaucer’s works, i.e. The Canterbury Tales, from the British Mediaeval period, and on to Shakespeare, John Bunyan’s Pilgrim’s Progress, and another Elizabethan hallmark, the King James Version of the Bible, translated in unrhymed iambic pentameter, making it as easily memorized as the plays of Shakespeare!
The great classical essayists such as Pope, Macaulay, Jonathan Swift, etc. are certainly an essential component of British Classics; 19th Century British classics would also include Charles Dickens, Jane Austen, Defoe, etc., and on into the 20th Century, including James Joyce of Ireland, William Butler Yeats, Graham Green, and on.

American Classics immediately bring to mind Mark Twain’s Tom Sawyer, Huckleberry Finn, Life on the Mississippi, Roughing It, all from the pen of a great 19th Century American journalist- humorist. The listing of American Classics would include, from the earliest New England Puritan literature, that of William Bradford, Anne Bradstreet, Cotton Mather, and on to Benjamin Franklin’s Autobiography, Essays by Alexis de Tocqueville of France ,observing mid-19th Century America [concluding that “what made America great was not in her manufacturing, political system ... but in her churches.”. American Classics certainly include Ralph Waldo Emerson, Henry David Thoreau, Walt Whitman, Emily Dickenson, Nathaniel Hawthorne and, fast-forwarding to Robert Frost (“Stopping By Woods on a Snowy Evening”), Ernest Hemingway’s WWI- period novels (For Whom the Bell Tolls, A Farewell to Arms,…), his epic novels, including The Green Hills of Africa, The Sun Also Rises, and Hemingway’s short stories collection, The Snows of Kilimanjaro, including “The Short Happy Life of Francis Macomber” as an example of his writing style that hooked a generation of American magazine and novel readers.

• Included in Modern American Classics would of course be John Steinbeck’s Grapes of Wrath, East of Eden, Cannery Row, and his short stories, including the most memorable, “Of Mice and Men”. Most recently joining the amazing list of American authors of Classics, I would add David Guterson, whose novels “Snow Falling on Cedars” recently made into a compelling movie, and “East of the Mountains” as emerging works, joining the ever-increasing American Pantheon of the Classics.

• All of this to document my appreciation and regard for the Classics: I have at least ten university-level courses recorded on my transcripts from Northeastern University, Boston, MA, and from Kearney, NE, State College, aka University of Nebraska at Kearney, and more recently, at the graduate level, from Wichita State University, Wichita, KS. This literary focus on my part is reflected in my own thesis above. Having studied various presentations of literary Classics in both British and American Literature survey classes, and having read many of the works I have cited, I believe that I am sufficiently well-informed and able to tutor any student needing assistance in the study of the Classics... Furthermore, because my State of Kansas/ KSDE certificates that I have held, most recently (2008-2011), validate me to teach secondary English and Journalism, that further qualifies me to tutor any student needing assistance in the study of the Classics.

Discrete Math

Discrete Math has its own unique mathematics profile, dealing with the study of functions, matrix math, permutations and combinations, the Binomial Theorem, Pascal's Triangle, fundamentals of probability, etc. with each topic a discrete math construct in itself, not dependent on other topics necessarily in the scope of a given Discrete Math course. Because I have accrued university-level engineering mathematics through Calculus I & II, and taught a variety of math courses, including Algebra I & II, Plane Geometry, Trigonometry, and Analytical Geometry, with an excellent math library at hand, I am well-prepared to assist any student needing tutoring helps in the study of Discrete Math.

Elementary Math

My qualifications for teaching elementary math are addressed initially by my Kansas Department of Education certifications in two levels of secondary mathematics, including Middle School math, issued initially when Middle School started in 6th Grade. Many aspects of 6th Grade math are included in 7th and 8th Grade Pre-Algebra texts, so it is a grade-level of teaching with which I am acquainted, and I am confident that I can successfully tutor any 6th Grader who has a determination, but needing practice with math skill sets required.


Because I have a B.A. in English and Journalism, I enjoy the related disciplines of reading and writing, teaching and tutoring English-class content. This also includes success with ESOL students needing tutoring in English studies.


The GED program is designed to allow students who opt out of the standard high school curriculum to study the same content (Math, English, History, Civics, etc.) in a compressed format which allows the individual to study and pass the GED high-school equivalency in a much shorter time. There is plenty of work, but because some students do have excellent background knowledge, it is easier for them to complete the GED at a much faster pace. I have personally "taught" / proctored GED classes, so am familiar with the challenges, including those for ESOL students.


I learned to enjoy the rigors of Euclidean Plane Geometry in my sophomore year of high school under the masterful teaching of a very strict teacher, who taught us to love the challenges of keeping a notebook of geometric proofs: memorizing axioms, theorems, and corollaries, and then being able to use them for the following problem sets and geometric proofs.


My qualifications for Golf Tutoring/Coaching are based on my three years as a caddy, my third year for our golf-course Pro Mike Brady, who tied for the US Open PGA Golf Tournament earlier in his golfing career, observing his professional play daily, and having enjoyed one free golf lesson from Mike every Friday of that third summer, and having enjoyed playing the game of golf several evenings a week during that four-year period, I have sufficient knowledge of the game: golfing etiquette, stance, swing, club selection, regulation play, score keeping, et al, many thanks to Pro Mike Brady.

As a coach, however, although I am limited by my age and not-so-supple golf swing, I can make helpful suggestions regarding “addressing the ball”, back-swing, follow-through, head-down (no watching for the trajectory of the ball until follow-thru has been executed). I would be able to coach at a golf driving range for two-three sessions, to coach a novice through the rudiments, after which a certified Pro would be the next and best, however, more expensive course of action.


Because I have a B.A. in English / Journalism, I enjoy English Language Arts, including the study of grammar and usage. I would be happy to assist anyone needing assistance with English grammar, including ESOL students, with whom I have also worked.


Since my English Education included a focus on American Literature, with the requirements of exposure to a background in English Lit, I do appreciate and enjoy returning to study and review of each, with the genre of the novel especially, also including Creative Writing, and the Elements of Fiction, so would be pleased to assist any student needing review via tutoring to be ready for the literature of high-school English / American Literature, or at the college level.

Microsoft Excel

Microsoft Excel is a powerful spreadsheet program with numerous practical applications in business, manufacturing, academics, research, etc. Because of its ability to organize data, complete calculations, utilize logic formulas, graph data in a variety of chart displays, i.e. column charts, pie charts, etc., Excel is an important PC tool for students and anyone entering the work force. Because I have taught six-week Excel classes, I would be happy to assist any student needing to learn Excel at a practical level, covering its basic high-lights for a variety of applications.

Microsoft PowerPoint

PowerPoint is a powerful speech presentation software package utilizing, in addition, a PC desktop projector, to illustrate text, graphics, and visual content, including photos, illustrations, graphics, and may also be enhanced by music or other audio features. It is very much like, in its purpose, to the use of the former OverHead (O/H) projectors used commonly in classrooms prior to the advent of PowerPoint presentations. It only requires the building of slides, again, very much like the former "Kodak slide projector”, except that your “slides” are built within your PowerPoint presentation. You are assigned, as the student, to learn Microsoft Office PowerPoint in order to make potentially amazing classroom presentations that even your teacher would be proud to present to the class, and, the good news is that it is easy to learn, with one step at a time. Again, I would be happy to tutor any student needing to learn PowerPoint.

Microsoft Windows

I have taught MS Windows classes, at least ten sections /12-hour sessions [1-hour per session], with a PC-overhead projector and all student with PC's in a computer-lab setting, using Thompson Publications "MS Windows" short course (10 units)[for the IAM-Boeing QTTP employees enrolled in this educational format [2004-2005. Wichita, Kansas].

Microsoft Word

MS Word is a very useful and powerful word-processing program, allowing the creation of a desk-top (PC or lap-top) publication of various documents, with built-in features of a journalism-to-print format, with instant "clip-board" cutting- and-pasting, selection of printer's font, style, size, etc. Anyone working with newspaper publications, high-school or college year-books, school newspapers, etc. prior to the advent of MS Word or similar word-processing programs, recognizes the supreme efficiency of "cut-and-paste"/ clip-board functions of MS Word, not to mention “Spell Checker”, as opposed to the time-consuming and pains-taking long-hand methods of scissors, tape, pasting of column inches to create and edit, for example, a tabloid newspaper page [with the attendant sweeping of cuttings from the composing room floor (!)], or other documents formerly from typewriter to-cut-and-pasting, literally, to prepare photo-ready copy with font-selection at the printing office for various applications. The genius of MS Word is that it captures at the PC keyboard most of the publishing requirements of a printed document, with the simple click-to-print. {Voila - !}


Physics is the study of the laws of the physical universe relating to the conversion and measurement of energy. Using the energy systems of an automobile as a model, how does a car start, move forward or in reverse, how does its battery preserve its charge, how does its horn work? The respective studies of kinetics, electrical conversions from the kinetic power of the engine via the generator, starter motor, fans, plus the acoustics and optics included in the design and use of the car horn and head-lights, tail-lights, all are addressed in a comprehensive Physics course. Because I have studied Physics both at the high-school and university levels, I would be ready and glad to tutor any student needing assistance in the challenges of studying Physics.


Because Prealgebra is an introduction to Algebra, the concept of using a variable, such as "x" or "y", to represent a real number is an initial step to getting the student, you, to become comfortable with this first level of going from the concrete operations of arithmetic to the abstract representation of the same operations in Prealgebra / Algebra, using variables [x,y,z, etc.] to represent the real numbers you would normally use in calculations: the use of variables and sign control, setting up and solving equations is a goal of Prealgebra.

Having taught Prealgebra for a number of years, I can only encourage students to get help when needed, and do the daily practice needed to develop skill, similar, in fact, to playing well in any athletic sport!


Precalculus is a challenging curriculum of advanced mathematics, drawing on the student's understanding and control of rational expressions, sign control, functions, exponential and logarithmic functions, analytical geometry, series, and trigonometry. It is a more advanced composite review with more depth of study of each of the above subjects. And also, it is an excellent preparation for the study of calculus, because calculus requires a confident working knowledge of these traditional disciplines of advanced mathematics, hence, its name appropriately, Precalculus.

Public Speaking

My qualifications for Public Speaking, after more than 25 years in public and private school-teaching and related venues, are directly related to class-room lectures, course materials presentations, in addition to Public Speaking as a college transcript requirement for my secondary teaching certification prior to college graduation.

In fact, I thoroughly enjoyed the challenges of my Public Speaking course, in which the various types of speaking were required to perform, including: (1) the Speech to Inform; (2) the Speech to Persuade, (3) the Speech to Entertain; etc. Posture, and eye-contact with the audience was emphasized, as well as demeanor, dressing appropriately for the occasion, etc.

With the combined experience of professional teaching as well as a memorable Public Speaking class in college, I am confident that I may be able to coach both the content and delivery style for any one needing tutoring in Public Speaking.


Reading, as a tutoring subject area, is essentially improving reading comprehension via a tutor's coaching within a desired grade level, such as 8th or 9th grade, with the added emphasis on reading speed, in order to attain efficiency. Tutoring any student in reading would require the use of reading comprehension study-and-practice manuals that provide timed tests and vocabulary, in order to measure improvement. As a reading tutor, my objectives for the student would be to increase reading comprehension, speed, and increased use of vocabulary, emphasizing the use of the dictionary to study the etymology of words (their origin, levels of meaning), and spelling.

Study Skills

Study Skills are an important element for success in high school and college curricula. For the college student, the guiding rule is "for every hour in class, plan on two hours of homework." Planning a specific quiet place to study, a definite time every day, the commitment to turning in homework on time, determining to study lesson content until the content is understood, by way of outlining, paraphrasing, keeping note-cards, etc. Having paper, pencils, pens, dictionary, rulers, etc. will make a study area so much easier to return to, and also, having assignments clearly recorded. In addition, having a friend from class to call if you missed the specific assignment is a great help, and then, having your instructor's office hours ready for a visit occasionally, actually, asking the instructor to describe the study skills needed for the particular course would also make a helpful guideline for you. Because I have more than 200 semester-hours of classroom time, I can speak from experience, and would be glad to work with any student willing to apply the study skills required for any given course of study.


I thoroughly enjoy the study and development of Trigonometry: I have taught the full course of Trigonometry in the classroom, as well as in tutoring my daughter in her high school Trigonometry class. In addition, I have taught many short courses in Right-Triangle Trigonometry, as well as for scalene (irregular)triangulation, using the Law of Sines and the Law of Cosines to solve for dimensioning on engineering drawings.


Vocabulary emphasizes, in addition to correct spelling, the meaning of a word in its context. To increase one's vocabulary, it is always helpful to read literature (autobiography, biography, novels, etc.) with a dictionary and note-cards, jotting down an unfamiliar word, and taking time to look it up. Because usage dictates, there are usually several definitions, the first being the most current, and the last being the oldest historical usage, in addition to the national origin of the word. To increase one's English vocabulary, reading with the regular use of (i.e.) Webster's Collegiate dictionary would be a great discipline in that direction.


The craft of writing is learned through the practice of writing, and different styles may be developed for different applications: newspaper journalism requires focus on the "5 W's": Who, What, When, Where, and Why. Letter-writing styles may vary, with the writer using a "voice" appropriate for the person being addressed. Scientific reports have specific guidelines, and certainly, the authors of short stories and novels have a "voice" (first-person, third-person, omniscient, etc.). For the short story or novel, the author definitely employs the added features of the elements of fiction: the opening setting or tone/atmosphere, characterization, plot, epiphany, and resolution. Because I have an English major, with a minor in journalism, and because I have enjoyed a detailed study of the elements of fiction, I would be happy to tutor any student needing “coaching” in the craft of writing!
