Credit vs. Savings

Do teens know the difference between saving up for a major purchase and borrowing for it? Do they know when it makes sense to borrow and when it’s more prudent to save?

1200px-visa-mastercardI had my grade 8 students explore those questions during a unit on percents. In their favourite homework assignment of all time, I asked students to think of a major purchase they wanted to make before graduation (approximately four years away). Their choices were interesting an varied: concert tickets, iPhones, travel, clothes… Continue reading

Undermining the Learner Profile

As members of the IB community, teachers at my school spend a lot of time planning and implementing strategies for cultivating the Learner Profile attributes in our students. This is exactly how it should be. The Learner Profile is central to the mission of IB and, as such, central to the mission of any IB school. Moreover, investing time and energy into proactively developing these attributes is a positive, strengths-oriented approach that is much more inspiring than a deficits-oriented approach. Thus, when it comes to the Learner Profile, our guiding question is “What experiences can we incorporate into our instruction that will help students to develop the Learner Profile attributes?”

From time to time, however, I think there is value in asking the more critical question, “What elements of of our instruction prevent students from developing the Learner Profile attributes?” This sheds light on some of the practices that might (unintentionally) be undermining our efforts in other areas.

In my own practice as a math teacher, I can think of a few habits that, unchecked, get in the way of my primary goal:

  • Teaching students tricks or shortcuts undermines their thinking skills if they are not required to first make sense of the algorithm.
  • Organizing assignments by topic or skill limits students’ thinking, as they follow the same procedure without having to identify the best skill to use in a given situation.
  • Providing all the necessary information for students to solve a word problem undermines their inquiry skills, and passes up a valuable opportunity for students to generate questions rather than answering questions supplied by the teacher.
  • Having students consult the answer key (or the teacher) immediately after solving a problem detracts from the value of reflecting on the cues available to determine if the solution is reasonable.

None of these habits is inherently bad, and they are all appropriate in some circumstances; however, if they become the standard operating procedure, students lose valuable opportunities to develop important traits. Imagine the unintended message we would send to students if the habits described above were entrenched in the routines of the class: repeat the process your have been shown (don’t think about what to do, how to do it or why it works), let the teacher ask the questions (don’t generate questions of your own), only the teacher has the answer. Together, these messages reduce students’ independence and self-efficacy.

Parents and teachers alike are constantly making decisions about how to help students develop character and intellect. There are too many decisions to make a pro-con list for every one; however, occasional reflection about the about the extent to which our habits support our goals will help to ensure our efforts yield the best possible result. When teachers and parents establish routines that are consistent with a shared goal, we support each other in developing students’ full potential.

 

Making “not knowing” useful

I recently came across this quote from Erica McWilliam’s 2008 article entitled, Unlearning how to teach.

Our highest educational achievers may well be aligned with their teachers in knowing what to do if and when they have the script. But as indicated earlier, this sort of certain and tidy knowing is out of alignment with a scriptless and fluid social world. Our best learners will be those who can make ‘not knowing’ useful, who do not need the blue- print, the template, the map, to make a new kind of sense.

What does it say about our current approach to teaching and assessment if our highest-achieving  students are not equipped for the future?

How do we teach our students to thrive in unfamiliar situations?

Some ideas that spring to my mind are…

  • making sure that students practice transferring knowledge and skills into new situations (I’ve written about this here and here).
  • making sure that assessment is more about monitoring progress than measuring performance (I’ve written about this here and here).

The Complexities of Graphing

I spend a lot of time thinking (and writing) about incorporating inquiry into my math classes. I often classify inquiry in math class into two different categories: math by inquiry and math for inquiry.line-chart-152153_960_720

Graphing is a great way for students to use their math skills for inquiry. From Kindergarten students using pictographs to visualize trends in the weather to humanities students analyzing government spending, graphing allows students to visualize relationships, make comparisons and formulate hypothesis in a wide range of fields.

Making it more about the questions than the answers

This year, I want to make my teaching more about questions than answers. Of course I want students to learn how to find answers independently, but I would also like them to find questions independently. In the spirit of being less helpful, I want to get my students extending problems, generating questions and learning to see math everywhere.

For example, what questions might this picture inspire?

Think-pair-share

I’ve been trying to be less helpful to my math students so that they can develop strategies for coping with unfamiliar situations. Last week, I had my final Math 8 class of the year. My students had been preparing for a year-end exam and I wanted to show them some sample problems so that they could focus their studying time on the topics in which they need the most practice. Truth be told, I also wanted to scare them a little bit, so that they would would take their studying seriously. Continue reading
