Scratch is an object-oriented programming language from the MIT Media Lab. It is now much easier to get started in Scratch thanks to a new release of the platform that "lives entirely in the browser".

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.

"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."

Personal and current piece by Audrey Watters who has just visited Seymour Papert. Introductory excerpt: "In most contemporary educational situations where children come into contact with computers the computer is used to put children through their paces, to provide exercises of an appropriate level of difficulty, to provide feedback, and to dispense information. The computer programming the child."

This is a bit long-winded and not quite the Woodward/Bernstein exposé it thinks it is, but provides a critical assessment of whether the scaling up economies of MOOCs tend to disappear when you add back the elements that make the course equivalent to fully-fledged masters degrees

I have been in touch with this writer before (he sent me a review copy of an earlier book and I blogged about it) on the off chance this might be any help
