You may call me David. I have taught Math 20 and Math 25 at LCC for over a decade. I more recently began teaching Math 52 and 105, and ABSE Level C Math.
My teaching philosophy is summarized by the motto celebrating eating an elephant together.
I let the pace of class be guided by student questions and discussion instead of planning out a weekly schedule before the term begins. The website's topics are carefully designed so we move forward with fundamental skills in the most clear and sensible order, and also have opportunities to take side trips that explore all kinds of interesting applications.
My personal interests include gluten-free baking (my wife is extremely Celiac), hiking, reading, computer and board games, and much more.
I have lots of silly and inspiring stories from my years of teaching almost every grade level from Head Start through college. Here are a few to ask me about:
Our class has a lot of homework. Students with an an average math foundation who want to be prepared for the final exam should expect to spend 4 to 8 hours each week doing homework.
Because we meet in Zoom you will need a reliable internet connection and a computer, tablet, or smartphone.
Please bring to class paper, a pencil, a highlighter, and a notebook.
You will need a scientific calculator that can do exponents and has a π key. A model with parenthesis keys and a fraction key is highly recommended. The online Desmos Calculator that is always linked at the top of our website works great. This Sharp is most popular for handheld calculators. Your smartphone might also work.
An optional resource is Basic College Mathematics by Charles McKeague. It has nice videos for every example problem. It is available as a physical book or an e-book. (If you buy the physical book, you also get the e-book for free.)
A very optional item is an inexpensive computer stylus and drawing tablet. Students who want to contribute to our online whiteboard during class and have kids attending school remotely might possibly find this purchase worthwhile.
Together our class times, study sessions, this class website, the textbook if used, and the videos and OER textbooks linked from the class website provide many different ways of understanding each math topic. Find the resources that work best for you!
One of your key tasks is to condense your class notes, thoughts, homework, and favorite example problems into an improved set of notes that you are allowed to use on the final exam. Preparing these notes carefully is invaluable!
For the sake of simplicity we will try to follow the official textbook one chapter per week. This textbook has lots of clearly explained example problems and good homework problems.
We will use this website to fill in what the textbook lacks: group activities, interesting readings, extension topics, and help with how to picture and think about most of the math topics.
This week, in addition to getting introduced to each other and to the course, we discuss the first textbook chapter, Review of Fractions.
Here are links to our Monday class jamboard and videos, as well as study sessions during the week:

7. Celebrate. Tell your instructor about any achievements you have completed, so those get checked off.
Instructor's notes to himself: the textbook never teaches reducing, and its example of least common denominator in 1.25 needs explanation. The website could use pictures for representational fluency of fractions and mixed numbers.
This week, in addition to making decisions about syllabus and grading, we discuss the second textbook chapter, Decimal Review.
Here are links to our Monday class jamboard and videos, as well as study sessions during the week:
| Week 2, Monday | about homework and grading | |

Instructor's notes: the textbook does not use decimal point scoots until section 6.4 with metric unit conversions, and the website lacks writing ratios that include a variable amount.
This week we work from two textbook chapters.
The textbook's third chapter is Operations with Integers. The two key subtopics are order of operations, and negative numbers.
The textbook's fourth chapter is a mish-mash of stuff named Formulas and Equations. This week we will talk about plugging numbers into equations, and also solving one-step equations. The rest of chapter four we do next week.
Here are links to our Monday class jamboard and videos, as well as study sessions during the week:

Instructor's notes: the website has little with integers aside from flushing out common background knowledge and avoiding common algebraic mistakes from assuming variables are positive— it should be in Mad Science more thoroughly; the book does no arithmetic with negative numbers after Chapter 3 but uses negative numbers in 4.7 for the coordinate plane, in 8.1/8.4 for exponents of scientific notation, and in 8.4 for the pH formula
This week we finish the textbook's fourth chapter. It is a mish-mash of stuff named Formulas and Equations. Last week we went over plugging numbers into equations, and also solving one-step equations. Now we finish up with proportions, variation, and some graphing.

The practice final page creates a new version each time you reload the page.
The specific version of the practice final we used during our last class is here, with a jamboard and video for requested problems.
By LCC policy, missing all classes and assignments during the first week causes you to be dropped from the class.
The Fall term holidays are Veterans' Day (Thursday, November 11th) and Thanksgiving (Thursday and Friday, November 25th and 26th). Neither is one of our class days.
You can add this calendar to your own calendar app using this ICAL address.
Please note that LCC policy allows students with three or more finals on the same day to reschedule one of them. Sometimes final exams may be taken early because of medical or other concerns.
LCC provides dumploads of resources to help students succeed. You can click on the image to the right to see my own compilation of student resources.
During remote terms the Math Resource Center, Tutor Central, other LCC tutoring centers, the college computer support, and many other student support offices all work together offering online Zoom help using the Lane Support Hub, which uses this Zoom room.
Fall term has KickStart Grants for up to $1,500 of financial assistance, with a deadline of October 4th but first come first served. Most students are eligible.
The link to start TRiO tutoring is http://lanecc.edu/meettrio.
Jennifer Sacklin (e-mail, appointment)works with STEP at Lane to offer advising, job search assistance, and help purchasing class books and equipment (requires receiving SNAP but not TANF, and a bit more).
It is often valuable to visit an Early Outreach Specialist who is trained to connect students to whatever resources can help. The one who normally works most closely with math students is Katherine Kaylegian (e-mail). Alternatively, Norma Scovell (e-mail is their Spanish speaker.)
Lane Community College is dedicated to providing inclusive learning environments. The Center for Accessible Resources coordinates all academic accomodations for students. If you anticipate or experience academic barriers due to a disability, to request assistance or accommodations, contact CAR at 541-463-5150 or accessibleresources@lanecc.edu.
All LCC classes adhere to the college's student rights and responsibilities and code of conduct.
You didn't click on my link to a big page of resources, did you? Then please at least click here to read about the many different workshops and other nice things offered by the college's advisors and counselors.
Distance learning is more immune to weather issues, but we should still know the routines...
Sign up for LaneAlert to receive e-mails or texts about weather closures! Log into mylane. In the Home tab, locate the box labeled Personal Information. Select the Lane Alert Emergency Notification link. Select which notifications you would like to receive. Scroll down to the very bottom of the page and click Save Changes.
You can also listen to KLCC (FM 89.7) or KUGN (AM 590 or FM 97.9) for campus closure information. You can also check the websites of LCC and FlashAlert.
If class is canceled or you are absent, please read ahead using the class website to familiarize yourself with the upcoming topics and assignments. Then we can more quickly cover the missed material.
LCC's website has more about its weather closure policies.
