    Free online grapher ... very nice graphics. Handles polar & Cartesian, function & inequality forms very well. No tools (intersection, etc.), but very nice, FAST graphics.

    Have you tried it on the iPad? Do you think it could replace the Virtual TI app?

    An interesting 'blog from Stanford's Keith Devlin (NPR's Math Guy) who is documenting his thinking as he prepares to offer a MOOC (Massively Open Online Course) on Mathematical Thinking.  This is an incredibly compelling read if you are interested in transition issues from secondary to college, the future potential of online courses, and/or mathematics education.

assessment exam write your own

shared by Chris Harrow on 22 Aug 12 - No Cached
  • “Here is the exam. Write your own questions. Write your own answers. Harder questions and better answers get more points.”
  • “Write a question you wish had been in this exam, and answer it”. As I recall some students didn’t appreciate that opportunity as much as I did.
  • One result of this strategy is that every student will be correct in their prediction of what will be on the exam. Regardless of which material is actually most important

  • I quickly figured out how to play that game successfully – success in that case being measured by my being able to solve under exam conditions, problems like the ones the teacher had shown us and we had practiced in class and done for homework.
  • In fact, you can’t separate real teaching from learning. They are simply two perspectives of the same human interactive process.
  • For whereas technology can provide instruction and can provide teachers and students with resources to assist them, what is cannot do on its own is teach them.

  • Learning to practice, this book vividly illustrates, takes time and effort, trial and error. It won’t happen tomorrow. But even a small movement in the direction of more practice will reap benefits, in teaching and many other things we do.

  • Origami may seem an unlikely medium for understanding and explaining the world. But around the globe, several fine artists and theoretical scientists are abandoning more conventional career paths to forge lives as modern-day paper folders. Through origami, these offbeat and provocative minds are reshaping ideas of creativity and revealing the relationship between art and science.

shared by Chris Harrow on 09 Mar 12 - No Cached
  • For many students, no matter their age, math begins with an answer. You then form a question, jeopardy style, to help disguise the number.
  • Most students learn to expect math questions and problems to be short, quick, to the point, solvable and structured around "clean" answers (often related in some way to integer components). They anticipate the answers before they anticipate the questions. I am not sure if they even consider the math.
  • They completely miss the point and the empowering strength of math process and pattern.

    This is a spectacular posting that could be used with ES or MS students (or possibly HS students, too) to explore square roots.

  • “I love the fact that wether [sic] we like it or not, or better put ‘wether [sic] we know it or not’, we are a part of an international, interemotional and integrating system. But who is studying everyone [sic]? That’s the beauty. We are not being studied by anyone, but we are studying ourselves. It is an amazing system of theories and use.”

    Some shameless self-advertising, and probably of interest only to math logic & curriculum wonks, but I believe there is a good argument for using a more inclusive definition of trapezoids.

    "So, learning math is somewhat like learning to read: we can do it, but it takes time and effort, and requires mastering increasingly complex skills and con- tent. Just about everyone will get to the point where they can read a serious newspaper, and just about everyone will get to the point where they can do high school-level algebra and geometry-even if not everyone wants to reach the point of comprehending James Joyce's Ulysses or solving partial differential equations."

  • “The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor.”
  • “[W]hen test scores become the goal of the teaching process, they both lose their value as indicators of educational status and distort the educational process in undesirable ways.”
  • New requirements to assess teachers based on their students’ scores, in particular, virtually guarantee even more cheating will take place.

  • Science in fiction affects our ability to understand science in real life.
  • Even ideas you think you can trust implicitly—like fingerprint evidence—turn out to have serious flaws that are seriously under-appreciated by cops, lawyers, judges, and juries.

Common Core standards reform

shared by Chris Harrow on 25 Apr 12 - No Cached
  • A quiet, sub-rosa fear is brewing among supporters of the Common Core State Standards Initiative: that the standards will die the slow death of poor implementation in K-12 classrooms.
  • By any accounting, the challenge of getting the nation's 3.2 million K-12 public school teachers ready to teach to the standards is enormous.

    There are actually! Come by my office and check out the book: Whistling Vivaldi by Claude Steele who's work these studies are based on. There are also really interesting results that pertain to race and stereotype threat which can inform our teaching practices to cater to students most impacted...

  • As children, most of us were told not to play with our food. However, when appropriately approached food can be a useful tool to teach children math and science. Science and math are throughout your house indoors and outdoors, especially in the kitchen.
