Embedded Tutor FTW!

Embedded Tutor FTW!

Comments 0 Comment

Thanks to the Transformation Grant, our college has begun to provide embedded tutors for developmental math and English classes. I have a tutor in each of my Math 200 (Elementary Algebra) classes. My tutors walk around throughout the class session, helping students and answering questions. I have had great results, and I am happy to say that my students feel that having a tutor in the classroom is very beneficial. Many developmental math students are much more comfortable asking questions…

New Algebra Review Strategy

New Algebra Review Strategy

Comments 4 comments

This semester I am teaching a short term intermediate algebra class. I taught this last year, and I taught a chapter each week followed by a week to review for the midterm. I repeated the same schedule for the final. This semester I have changed the schedule and have had great success. After I finish covering each chapter, I devote a day to reviewing that chapter immediately. I bring in an old copy of a chapter exam, and the review…

My 3 R’s and Mindset

My 3 R’s and Mindset

I took last semester off (bank leave), so Monday will be the first day teaching students in about eight months. What did I do during that time? I worked on the three R’s: resting, reading, and redesigning my classes. Resting I have taught a full load of classes every semester (and nearly every summer) since I started at College of Sequoias back in 1994. I did not think I needed a break because I did not feel the burnout that…

Discovery & Reflection in Developmental Math

Discovery & Reflection in Developmental Math

I’m in the middle of a one-semester leave, and in addition to working my way through Euclid’s Elements I have really cranked up my reading in anticipation of my return in Fall. I am currently reading Jo Boaler’s Mathematical Mindsets. I was happy to see that she supports my beliefs that student learning increases when students participate in the discovery of concepts as well as when students reflect on their learning. These have been two areas of emphasis for me…

Problems To Use In Class

Problems To Use In Class

One thing I like to do in class is end with a short assignment to see how well students understand the material from that section. There are a couple of short quizzes that are available in the 4th edition of my combined elementary & intermediate algebra textbook. First, in the Video Notebook (located for students inside MyMathLab) each section of the notebook ends with a 5-question self-assessment quiz that works really well for this purpose. I selected 5 problems that…

Factoring Trinomials (x^2+bx+c): Sometimes You Should Start With b, Not c

Factoring Trinomials (x^2+bx+c): Sometimes You Should Start With b, Not c

Comments 0 Comment

In today’s class we ran into the trinomial This can be challenging for students just learning to factor because they are not familiar with the factor set of 208. Traditionally I recommend that students follow the 10-second rule: If you cannot find the correct factor pairing within 10 seconds, you should move on to listing all factor pairs of c. This would result in the following pairs: That means that students need to try 13 potential factors (1 through 13)…
