Experiments in assessment

Here a few experiments in assessment I’m considering for next year. Compare the results between an oral assessment (as in, find out what they can tell me they know verbally) and a traditional test. . Question: How much of a difference does the mode of assessment make?   Compare the results between a 10 minute […]

Mathematics in the real world: World Statistics

This is another post in my series on mathematics in the real world.     Thanks to a colleague of mine, I rediscovered the Google Public Data explorer. Within 10 minutes, I had constructed the above graph, which shows adolescent fertility rate for 15 to 19 year olds, versus life expectancy, measured against (look at […]

What is math?

This image is an attempt to capture the important stages of doing mathematics. As pointed by other people, mathematics is not a linear process, which I am attempting to share via this image. I see analytical reasoning, flashes of insight, and exploratory calculations as the glue that holds these stages of mathematical thinking together.   […]

Why math instruction is unnecessary

This TED talk by John Bennett raises an important question; why do we teach middle school and high school math?   I don’t know if using "puzzles" is a scalable solution for the problems in mathematics instruction in middle schools and high schools. It would probably work for many math teachers, but wouldn’t necessarily work […]

Computer based math presentation

Here are the slides from my presentation for the Global ed conference on Computer Based Math. I will share the presentation recording when I have it, as I had some great questions from the audience. If you are interested in discussing these ideas further, join the Linked In group. If you want to challenge my […]

Prepare students for life, not jobs

Should the goal of schools be to prepare students for jobs when they complete school? The answer to this question seems to be obviously yes to many people, but this naive answer is problematic for a few reasons. At the end of the 19th century, many educators agreed, the role of schools was to prepare […]

Mindshare Learn summit in Toronto

Yesterday I participated in the Mindshare Learning summit that happened at York University in Toronto. With only one exception, the talks and panels were very interesting, and I was pleased that almost no one said, "we need to prepare students for the needs of industry." Here is the summary of the tweets for the day. […]

Three modalities of learning via computers

I think most learning opportunities through computers can be broken down into one of three basic modalities. These modalities may be mixed (as is the case when one uses adaptive assessment, for example) or they may be a stand-alone use.   Computers as assessment This is the lowest level of computer use, in my opinion, […]

Objections to computer based math

At the conference I was at in London, we were discussing, what would a mathematics curriculum look like if the computational step of doing mathematics was something students did using a computer? Update: The video from this session has been posted by the Computer Based Math organization. See below.   Here are some objections shared […]

Math is not linear

Blanca Parra shared this Prezi with me, and I love it. It’s going into my collection of resources I can share with people about how we can change mathematics education. I wonder if we could get RSA animate or someone with similar skills to create a video related to this.   Math is not linear […]
