This semester I have been using the Interwrite Personal Response System (see http://www.interwritelearning.com/products/prs/radio/detail.html) in the classroom. Instructor using this system prepares questions that will be shown to the students on a video projector screen in the classroom. The questions are multiple choice, and students answer by clickers.

I have been in the business of producing calculus podcasts for a while. Now we experimented reproducing a mathematical talk as a podcast. Together with Emil Volcheck and Tony Shaska I organized a special session at the Joint Meeting of the AMS and MAA that took place in Washington, DC this January. Emil had a Zoom H2 portable audiorecorder that we used to record Peter Buser’s talk. Together with Buser we then recreated the slideshow, and matched that with the recorded audio. The result is available at http://gallery.me.com/mika.seppala#100437.

We have now taken some small measures to improve the navigation on the website. this was done by adding breadcrumbs for individual nodes on the site, eg. the dissemination items, deliverables and some others.

You can now use the breadcrumbs to navigate directly back to the pages where the dissemination items etc are listed instead of having to go through the menu, for example:

Here is a nice collection of use cases for wikis in education. Nothing particularly related to mathematical education, but most of the uses cases are so general that they can be well adapted to our needs.

To get a true picture of the performance differences, I took snapshots of CPU and memory usage of Mac Pro and of MacBook Air while the computers where producing the movie discussed in my previous blog entry.

The picture above shows the CPU usage of my Mac Pro, and the picture below that of my MacBook Air.

We have done some customization on the views for the JEM partner pages.

For your comfort, we have added a listing of each partners dissemination items, case studies and software to the pages at About JEM -> The JEM Network -> <Partner Name>.

Any suggestions for improving the partner pages further are welcomed :)

I am spending a lot of time with podcast production. During the process of learning this trade I have gone through lots of hardware and software. From Windows to Mac, from USB microphones to condenser microphones etc.

We have this morning upgraded the menu system of the JEM portal. Please report if you notice any strange behavior :)
