The figure below shows a rectangle with width 3 and height y. The product 3y represents the area of the 3-by-y rectangle. Change the value of y by dragging the red point up and down the vertical axis. Note that as the point is dragged, the area of the rectangle changes simultaneously.
This is a great exploration for students to begin making connections between whole number multiplication and decimal multiplication. One modification I would make is to have students make a partition (on grid paper) to show the partial products so I could connect the figure to a symbolic algorithm for multiplication and the distributive property. For example, if it was 1.2 x 3, the partial products might be (1x3) + (.2 x 3).
Basic Item Analysis for Multiple-Choice Tests.
Jerard Kehoe,

This article offers some suggestions for the improvement of multiple-choice tests using "item analysis" statistics. These statistics are typically provided by a measurement services, where tests are machine-scored, as well as by testing software packages.
The basic idea that we can capitalize on is that the statistical behavior of "bad" items is fundamentally different from that of "good" items. Of course, the items have to be administered to students in order to obtain the needed statistics. This fact underscores our point of view that tests can be improved by maintaining and developing a pool of "good" items from which future tests will be drawn in part or in whole. This is particularly true for instructors who teach the same course more than once.
Recently I have been contemplating how we might define inquiry. Like many terms in education, it is often used in multiple contexts and has a range of meanings attached to it. Coming to agreement on what inquiry is, requires negotiating seemingly divergent understandings. If we are to avoid oversimplifications and dichotomous thinking, we need to explore these multiple perspectives and find a balance point.
This week they are talking about having multiple users being able to log into chrome at once. This is not the "sign-on as a different user" setting in Google Apps, but rather being able to have a second set of bookmarks, formdata, theme and more by signing in as a second user into chrome.

"School officials focused exclusively on bullying prevention efforts might want to consider the findings of a new study showing the highly damaging effects of multiple forms of victimisation on school climate.
The study, published in the Journal of Child & Adolescent Trauma, measured the impact of polyvictimisation - exposure to multiple forms of victimisation - on school climate at the middle and high school levels. Results show that bullying, cyberbullying and harassment were significantly associated with decreases in perceptions of school safety, connection, and equity."
