Article based on an interview with one of the authors of a new study about the importance of teachers' understanding student misconceptions. [The full paper is available here if you have access to the journal http://aer.sagepub.com/content/early/2013/03/06/0002831213477680.full.pdf+html] Excerpt from the paper:"An intriguing finding of this study is that teachers who know their stu- dents' most common misconceptions are more effective than teachers who do not. This particular component of PCK may allow teachers to construct experiences, demonstrations, experiments, or discussions that make students commit to and then test their own ideas. A teacher knowing only the scientific ''truth'' appears to have limited effectiveness. It is better if a teacher also has a model of how students tend to learn a particular concept, particularly if there is a common belief that may make acceptance of the scientific view or model difficult. This finding, too, has practical implications. In PD programs, an emphasis on increasing teachers' SMK without sufficient attention to the preconceived mental models of middle school students (as well as those of the teachers) may be ineffective in ultimately improving their students' physical science knowledge."

This book will familiarize you with the Scratch visual programming environment, focusing on using Scratch to learn computer science. The book is structured as a collection of tasks. Each chapter teaches a new concept, but the concept is introduced in order to solve a specific task such as animating dancing images or building a game. Each chapter starts with a simple task, but as soon as we solve one task, we add additional tasks to extend the existing task. The sequence of tasks will require a new construct of Scratch or the use of constructs you know in new ways.

You can sign up here for a Udacity 10 minute "mini-MOOC", which from the fact of its target audience, is likely to have been very carefully implemented by Udacity. The promotional video gives some pointers to why Udacity withdrew (their focus is increasinly firmly on "higher" stuff). The min-MOOC should be seen in the context of Udacity wanting to attract Google-focused programmers onto its just launched $7000 Computer Science Masters, done in partnership with Georgia Tech.

Not the clearest learning experience I have known.

I particularly resent the "happy-clappy" over-enthusiastic tone of the feedback

"I am obliged to say something about calculators and computers. You would protest if I did not. I could refuse because I can prove I am incompetent. I know almost nothing about calculators and computers. It is a lack of knowledge that prevents me from tackling any minor problem of calculators and computers in mathematics education. It does not prevent me from indicating what in my view is a major problem. "Technology influences education. The ballpoint, Xerox, and the overhead projector have fundamentally changed instruction. But this is as it were unintentionally educational technology. Programmed instruction, teaching machines, language laboratories, which were intentional educational technology, founded on big theory, did not fare as well, to say the least of it. "Calculators are being used at school, and they will be used even more in the future. Computer science is taught and will be taught even more. How to do it - these are minor questions. Computer assisted instruction has still a long way to go even in the few cases where it looks feasible. " What I seek is neither calculators and computers as educational technology nor as technological education but as a powerful tool to arouse and increase mathematical understanding."

These are worth reading: 1. "Udacity: Creating A More Engaging MOOC" by David Carr in the 30/7/2013 Information Week.

Georgia Tech Computer Science teacher Mark Guzdial is a thoughtful (and in this instance somewhat geeful) opponent of MOOCs. His comment on an introductory physics MOOC that Georgia Tech ran with Gates Foundation funding are interesting. The completion rate was exceptionally low (less than 1%). The completers: "fell into three categories: those who came in with a lot of physics knowledge and who ended with relatively little gain, those who came in with very little knowledge and made almost no progress, and a group of students who really did learn a lot". According to Guzdial, they don't know why nor the relative percentages yet.

50 minute presentation on use of Scratch to teach some maths concepts 10-year-old and 16-year-old kids. Interestingly even the 16-year-olds thought the cat made it look like "kids stuff". There's a recording of the full presentation at https://sas.elluminate.com/site/external/recording/playback/link/table/dropin?sid=2008350&suid=D.9FA226957D30A14AB25F33DEBBF5D3 (note worth using the Blackboard recording rather than the video, even though it's more of a faff, as the former includes a shot of the speaker where he demonstrates things physically, whereas the latter just shows the presentation)

This reads as if it has had the attention of a PR person. Here is the key para concerning maths: "We know that students learn at different speeds. This is particularly the case in the mathematical sciences, where it just takes a while to really understand certain concepts. Rushing students through a timed curriculum with a pre-defined pace cannot be the best way to achieve lasting success. In our remedial math class, we only gave students a single chance to pass various exams. If they even failed the first midterm, they failed the class. On campus, multiple chances are offered. There are clear opportunities to rethink assessment as a whole, especially as we open up new pacing options."

It feels to me there are important lessons from this that should be incorporated in our Marketing and Learner Engagement work. e.g. how much do we leave it open vs target hard-to-reach learners
