### Connections: Challenge By Choice

After writing about Challenge by Choice, from the teacher experience in previous posts, I was fortunate to be featured in Connections Magazine for that work, where Jessica More wrote thoughtfully about some great student work. I am thankful for her work!

A few days before the exam I posted this video predicting the first problem and came pretty close…

### What Is My Main Goal of My Calculus Course

I recently ran into a student that I taught during my first year of teaching (ten years ago) what he remembered from my Calculus course. He remembered the word derivative and that we had to do problem sets and if he did well on those he would do well on the tests. But he didn’t really remember any “Calculus”. He works in marketing and- I assume- does not need to use any of the rules, theorems, or formulas particular to Calculus. But, I bet he has a better appreciation of the concept of *change* because of my course, even though he might not attribute it to my course; at least I hope he does.

So, What do I want my students to remember five or ten years after they leave my course? Really the question I am asking is “What is my main goal in my calculus course?”

For me, the answer is change. Algebra 2 and PreCalculus are about functions and points on a graph (I don’t love that description, but its serves my purpose), while Calculus is about the *change* at those points. Imagine Algebra 2 is about the point, and Calculus is about the slope at that point. So, as we returned from Spring Break- and were technically in the middle of our unit on the Fundamental Theorem of Calculus- I tried to gauge what my students remembered about Calculus after ten days away…

They looked in their notes and said things like chain rule, fundamental theorem of calculus, derivatives, and change. They also have every standard example in their notes (think volume of a balloon for related rates) that they can use in future Calculus courses as a resource (I have anecdotal evidence that they refer to these notes in college), but as I tried to dig deeper into what this course engrained in them, I was not sure that more than a few understood what I meant by *change*.

SO, I talked to a physics teacher who was excited to collaborate. I borrowed some “logger pros” and Vernier sensors to begin a two-day task/project/lab/experiment. Here it is:

The outcome of this “task” will be to:

- describe a movement in words
- By hand, graph:
- distance vs. time graph of the movement
- velocity vs. time graph of the movement
- acceleration vs. time graph of the movement

- demonstrate the movement
- use the “logger sensors” to create an actual capture of the movement, including distance, velocity, and acceleration graphs
- verify that the description, movement, and graphs all correspond
- determine a means to present this information

We are going to spend two days on this task, then return to our normal progression of finding area between two curves. But for these two days we’re going to try to see if we can reinforce what I believe to be the central theme to Calculus.

Maybe in ten years, they’ll remember this.

### Disruptive Innovation Transforms

“There is an indirect relationship between the number of times an institution uses the term *Innovation* and how innovative the institution actually is.”

I came across a New Yorker article from the summer (linked here) that applied concepts from Clayton M. Christensen’s 1997 book “The Innovator’s Dilema” to the current culture of technology, start-ups, and education. Christensen’s premise is that innovation takes two forms: sustaining innovation and disruptive innovation. Sustaining innovation is analogous to R&D- it is based on improving the current product. Disruptive innovation is blowing up the system; it means starting from scratch or reinventing.

The article, written by Jill Lepore, briefly discusses the history of Harvard University and the introduction of Massive Open Online Courses. These courses were thought to open up opportunities for anyone not able to attend Harvard, and to be substitutes for the courses taught there. But are MOOCS, or online learning in general disruptive? Is teaching a hybrid class disruptive? Or are current trends innovating education simply sustaining innovation?

What would a true disruptive innovation to education look like?

### The Schedule Makers

I always assumed Major League Baseball’s schedule was constructed using some intense algorithm. It seems that for twenty-five years MLB used human intuition to construct their elaborate schedule. It seems like now programming and computer programming sophistication has caught up.

This is a worthwhile twelve minute video by ESPN’s 30 for 30 series (directed by Joseph Garner). Also a worthwhile graph theory application.

### Challenging Routine

Two months ago, as the school year was beginning, I read a handful of articles discussing the correlation between productivity and routine. Business journals, blogs, tweets, and newspapers praise the importance of routine. Wake early, exercise, browse headlines before leaving for work. Work on creative tasks in the morning and mechanical tasks later in the day. Make lists and wind down before sleep. Setting a routine and completing tasks based on that routine would certainly make anyone more productive.

Whether we consciously follow a routine or not, we all have daily patterns. As a teacher, my class has a routine; over time patterns emerge and habits form. Deviations from our routine signal importance. We are doing something different for a reason. I hope to encourage my students to realize that changes signal importance. I hope to say: “Hey look, we are doing we are doing something different!”

Those moments only happen when the routine is broken. This past summer, my day-to-day routine changed as I worked for a summer program on a rural college campus. I had to run at different times of the day and worked until later in the evening. My entire routine- mental and physical- changed and my body responded as if to say: “Hey look, we are doing we are doing something different!”

Ultimately, a routine will put us into a position to complete our daily tasks and be productive. But those moments of innovation or ideas sparking in our minds will only happen if we consciously break our routine. Consider Google’s “20% time,” which is the one day per week that employees spend time working on side projects. This time is a structured (our routine) break of routine. This time has been lauded as the nest egg of innovation.

Personally, this blog is my opportunity to break away from my day-to-day routine of teaching, coaching, and economic researching. I need to make this break of routine a common activity; it is an opportunity for me to think through issues and current events and put my thoughts on “paper.”

Breaking away from our day-to-day habits gives us opportunity and the signal that our task is worth the time. Within the framework of the routine encouraged by productivity experts, we can incorporate intentional breaks to signal importance and generate opportunities for growth.
