Geoff Roulet and Jill Lazarus will discuss their use of wikis, GeoGebra and Jing with students, and invite participants for an extended DIY exploration. More details concerning the software required are below. All events in the Math Future weekly series: http://mathfuture.wikispaces.com/events The recording will be at: http://mathfuture.wikispaces.com/SupportingCollaborativeMath Your time zone: http://bit.ly/z69yzS About Blended Mathematical Collaboration using a Wiki, GeoGebra and Jing This discussion centers on the use of computer tools in a high school class. The goal was to develop a "math-talk learning community" to establish mathematics communication and collaboration as a classroom norm. In support of this we have combined the use of a wiki, GeoGebra, and Jing. We would like to invite educators who have experience with wikis, GeoGebra and screencasts, or who would like to learn more, to discuss our project and share their ideas. Event Hosts Geoff is the skipper of and Jill a crew member on Jeannie, a J35 racing yacht. When not sailing, they are mathematics educators. After graduate work at the University of Waterloo, Geoff Roulet began teaching mathematics, computer science, and chemistry at Roland Michener Secondary School in Timmins, northern Ontario. In the late 1970s, when personal computers for computer science were placed in the back of his classroom, Geoff began using these to support student learning in mathematics. Since then he has been involved in ICT use in teaching and learning at all grades and in all subjects, but with a particular focus on mathematics. Teaching was followed by a short spell of curriculum development and support work with the Ontario Ministry of Education and then in 1990 a move to the Faculty of Education, Queen's University at Kingston. Along the way Geoff completed M.Ed. and D.Ed. degrees at the Ontario Institute for Studies

Girls who play video games are three times more likely to choose physical science, technology, engineering or maths (PSTEM) degrees compared to their non-gaming counterparts, according to new research from the University of Surrey

From the National Center of Education Statistics: "The Trends in International Mathematics and Science Study (TIMSS) 2011 is the fifth administration of this international comparative study since 1995 when first administered. TIMSS is used to compare over time the mathematics and science knowledge and skills of fourth- and eighth-graders. TIMSS is designed to align broadly with mathematics and science curricula in the participating countries. The results, therefore, suggest the degree to which students have learned mathematics and science concepts and skills likely to have been taught in school. In 2011, there were 54 countries and 20 other educational systems that participated in TIMSS, at the fourth- or eighth-grade level, or both. The focus of the report is on the performance of U.S. students relative to their peers in other countries in 2011, and on changes in mathematics and science achievement since 2007 and 1995. For a number of participating countries and education systems, changes in achievement can be documented over the last 16 years, from 1995 to 2011. This report also describes achievement within the United States by sex, race/ethnicity, and enrollment in public schools with different levels of poverty. In addition, it describes achievement in nine states that participated in TIMSS both as part of the U.S. national sample of public and private schools as well as individually with state-level samples of public schools."

From the abstract: "This research examined the effects of the objectifying gaze on math performance, interaction motivation, body surveillance, body shame, and body dissatisfaction. In an experiment, undergraduate participants (67 women and 83 men) received an objectifying gaze during an interaction with a trained confederate of the other sex. As hypothesized, the objectifying gaze caused decrements in women'smath performance but notmen's. Interestingly, the objectifying gaze also increased women's, but notmen's,motivation to engage in subsequent interactions with their partner. Finally, the objectifying gaze did not influence body surveillance, body shame, or body dissatisfaction forwomen or men. One explanation for themath performance and interaction motivation findings is stereotype threat. To the degree that the objectifying gaze arouses stereotype threat, math performance may decrease because it conveys that women's looks are valued over their other qualities. Furthermore, interaction motivation may increase because stereotype threat arouses belonging uncertainty or concerns about social connections. As a result, the objectifying gazemay trigger a vicious cycle in which women underperform but continue to interact with the people who led them to underperform in the first place. Implications for long-term consequences of the objectifying gaze and directions for future research are discussed."

Wow, what an amazing study!

"This model for learning mathematics may be quite different from what teachers experienced themselves in the past where classrooms were less interactive, filled with little activity and conversation. Teachers were generally in control, directing all aspects of what was to be learned; different points of view and approaches seldom brought to the surface new ideas and insights and a high degree of redundancy meant that everybody learned the exact same thing at the exact same time.

Numbers can't "talk," but they can tell you as much as your human sources can. But just like with human sources, you have to ask! So what should you ask a number? Well, mathematicians have developed an entire field - statistics - dedicated to getting answers out of numbers. Now, you don't have to have a degree in statistics in order to conduct an effective "interview" with your data. But you do need to know a few basics. Here, described in plain English, are some basic concepts in statistics that every writer should know...

These pages demonstrate visual phenomena, and »optical« or »visual illusions«. The latter is more appropriate, because most effects have their basis in the visual pathway, not in the optics of the eye. When I find the time I will expand the explanations, to the degree that these phenomena are really understood; any nice and thoughtful comment welcome.

"Technology has inevitably been inserted to nearly all aspects of our lives today. First and foremost, the use of computerised cash registers have been around for a few decades now. Trying to remember cash registers which operated without a digital display might be nearly impossible. The generation which might be able to do so has been replaced with a new generation who depend on technology to a large degree. The dependence on new technology is starting to 'show signs' of the effect of converting from our analogue counterparts. Below is an example that I recently experienced the effect of technology in a transaction at a doughnut shop."

A college institutional researcher reveals some data concerning math placement tests and the pressures impacting students to opt for more difficult math courses without adequate preparation and unsatisfactory results. He writes: "In my mind, this disconnect exemplifies the degree to which incoming students and families don't grasp the difference between going to college to acquire content knowledge and going to college to develop skills and dispositions. ... [I]f students understand that college is about developing skills and dispositions, I think that they might be more likely to appreciate the chance to start at the beginning that is appropriate for them, savoring each experience like a slow cooked, seven course meal because they know that the culmination of college is made exponentially better by the particular ordering and integrating of the flavors that have come before."
