Bernoulli substitution Entry #180 18 Feb 2021 11:26 am Dina Yagodich 0 comments I was searching for a good scenario to demonstrate the type of problem that a Bernoulli substitution would solve... only to find out that it was more a cool exercise that three different mathematicians played around with, rather than modeling something real. I now wonder what is the benefit...
Follow up on Kool-Aid scenario Entry #179 10 Feb 2021 9:35 pm Dina Yagodich 0 comments As students are completing the third section on their own, I'm getting many panicked emails -- that they are getting weird, large or small numbers. I tell them to graph it to see if it matches what they think should happen. And "real life is not as pretty as fake problems in...
Weeks 2 and 3 Entry #178 09 Feb 2021 8:10 pm Dina Yagodich 0 comments Week two -- I warned students to watch the 'how to solve separable equations' video I had posted prior to class. In the workshop class, we worked on the 'Dog drug' scenario. I broke them into groups of 4 and told them to dig in! As I experience every year I do this --...
Week 1 went well! Entry #177 30 Jan 2021 12:49 pm Dina Yagodich 2 comments The students completed the first two scenarios in the remote class on the hotel population -- without new guests being added and then with new guests being added. They had to complete the 'with new guests being added' with 5 different initial values to show a nice family of curves...
Synchronous remote - a perfect time to go all in for modeling first! Entry #176 25 Jan 2021 8:10 pm Dina Yagodich 0 comments When deciding how to set up my Differential Equations class this semester, knowing it was fully online with synchronous remote sessions twice weekly, I was thinking about how to break up lecture. Then... it hit me. I have all my lecture videos recorded from when I teach Diff Eq online...
Half way through Week 5 Entry #171 26 Feb 2020 10:09 pm Dina Yagodich 2 comments Somehow this semester is just zipping by - it's hard to believe we are in the middle of Week 5! The adapted 1-111 Spread of Information is uploaded to the Google Drive I've shared here -- this was mentioned in my Week 2 Blog post:...
Week 2 Entry #168 06 Feb 2020 11:30 pm Dina Yagodich 1 comments It's the end of week two! The end of week one was focused on direction fields -- I tell students about the following links: Slopes (for Apple...
Spring 2020! Entry #167 29 Jan 2020 3:04 pm Dina Yagodich 1 comments I'm fresh off of the JMM meetings where I helped with one of the Minicourses on SIMIODE. I met some great new people and reconnected with old friends (not age, but how long I've known them.) This is a great community - I'm always learning new things. I also came back...
Week 2 - How it's going! Entry #140 06 Feb 2019 11:55 am Dina Yagodich 1 comments I've had three classes so far this semester (managed to get a snow day in week 1...). Here's an update. Day 1: M&M modeling and basic definitions, Precalc/Calc I/Calc II review Day 2: Verifying Solutions and Initial Value Problems (IVPs), Basic Modeling, Direction...
The day before school starts... Entry #137 27 Jan 2019 8:31 pm Dina Yagodich 2 comments I've got my m&m's ready to go! Just finished my syllabus (file:Yagodich_D_MA213-1_Spring_2019.docx not found), my course outline (file:MA213_Sping_19-1_Tentative_Course_Outline.docx not found) and my first quiz (file:Quiz1.tex not found). It's a take home quiz...
Welcome to Spring 2019! Entry #136 21 Jan 2019 11:58 am Dina Yagodich 2 comments I'll be posting a few ideas/thoughts that came out of attending the JMM (Joint Math Meetings) in Baltimore last week. There are some changes I am going to make to my classes this semester from what I've learned. But first, I would like to answer a question that I received...
Approaching the midterm Entry #17 04 Oct 2015 2:09 pm Dina Yagodich 0 comments I am really enjoying the Lebl book -- there is no teacher solution, but when I was stuck on a problem, a quick email to the author got resolution. I used the Schaums book for that section. I really like the way the Lebl book handles homogeneous second-order linear ODEs as well as...
This week in Diff Eq... Entry #16 16 Sep 2015 12:06 pm Dina Yagodich 0 comments I am teaching Exact equations and substitution methods this week. I wasn't able to find a good modeling activity, so I won't be doing modeling specifically this week. Next week I will be doing numerical analysis, so I hope to find a good modeling project. The textbooks I am...
Day 3 of using modeling Entry #10 09 Sep 2015 9:03 pm Dina Yagodich 0 comments Today I taught how to solve 1st order diff eqs using the integration factor. This is one I derive because I think it's too magical to say "use mu = e^(integral P(x) dx)". My favorite and most successful way of teaching this is to show the steps, say, "Hey,...
Open Source for the first time Entry #8 02 Sep 2015 10:35 pm Dina Yagodich 1 comments This semester, I have switched from Zill's book to an open source book. I liked Zill - but it cost students over $200. Since I teach at a community college where the class itself is only about $400, having a book half the cost of the course seemed excessive. The book I am...
