Many Eyes is a data visualization platform designed by IBM and provided for free. Since it's IBM it should remain fairly stable and free for a long while.
"Italian psychologist Geatano Kanizsa first described this optical illusion in 1955 as a subjective or illusory contour illusion. The study of such optical illusions has led to an understanding of how the brain and eyes perceive optical information and has been used considerably by artists and designers alike. They show the power of human imagination in filling in the gaps to make implied constructions in our own minds.
Kanizsa figures and similar illusions are a really useful way to encourage learners to 'say what they see' and to explain how they see it. It offers a chance for others to become aware of the different views available in a diagram and share their own thoughts without the 'danger' of being wrong; many people see different things."
"Chances are you've seen this symbol before, because it's one of the most well-known Egyptian symbols. It's called the Eye of Horus. It's been in the background of plenty of mummy movies, and been turned into a lot of necklace charms. Some people think it's writing. Actually, it's math."
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.
"I began my personal journey into the world of Cubing when I was attending Regis University in Denver, Colorado in 2009. My senior thesis project involved devising a cryptosystem using the Rubik's Cube to encode and decode messages. Although my involvement with the Rubik's Cube waned post-graduation, it was rekindled shortly after I became a secondary teacher of mathematics in 2014. I had several Rubik's Cubes in my possession from my college days and these decorated the shelves in my classroom. I recall these puzzles catching the eyes of many curious pupils. After months of traditional curriculum presentation, I determined that my students were in need of a novel lesson, one that would ignite a passion for problem-solving. This lesson would involve the colourful and alluring hexahedron puzzle on my desk: the Rubik's Cube."
Abstract:"Prime Climb is an educational game that provides individual support for learning
number factorization skills in the form of hints based on a model of student learning. Previous
studies with Prime Climb indicated that students may not always be paying attention to
the hints, even when they are justified (i.e. based on a student model's assessment). In this
thesis we will discuss the test-bed game, Prime Climb, and our re-implementation of the
game which allowed us to modify the game dynamically and will allow for more rapid prototyping
in the future. To assist students as they play the game, Prime Climb includes a pedagogical
agent which provides individualized support by providing user-adaptive hints. We
then move into our work with the eye-tracker to better understand if and how students process
the agent's personalized hints. We will conclude with a user study in which we use eyetracking
data to capture user attention patterns as impacted by factors related to existing user
knowledge, hint types, and attitude towards getting help in general. We plan to leverage these
results in the future to make hint delivery more effective."
Forthcoming June 2012: "From the pyramids and the Parthenon to the Sydney Opera House and the Bilbao Guggenheim, this book takes readers on an eye-opening tour of the mathematics behind some of the world's most spectacular buildings. Beautifully illustrated, the book explores the milestones in elementary mathematics that enliven the understanding of these buildings and combines this with an in-depth look at their aesthetics, history, and structure."
"In this paper, we will describe work that we have done in this direction using as a test-bed an edu-game for number factorization, Prime Climb. This game includes a pedagogical agent that provides adaptive interventions during game playing based on a model of student learning [13, 18]. Here we focus on how we re-implemented the original Prime Climb game into a framework that enables rapid prototyping and testing of different design hypothesis. We also discuss preliminary work on using eye tracking data on user attention patterns to better understand if and how students process the agent‟s adaptive interventions." (from the introduction)
Great new way of visualizing data (all kinds of data sources). Make wordles, graphs, webs of all kinds of information. Also a great place to get data sets for investigation in the classroom.
Mathematics Teacher Noticing is the first book to examine research on the particular type of noticing done by teachers---how teachers pay attention to and make sense of what happens in the complexity of instructional situations. In the midst of all that is happening in a classroom, where do mathematics teachers look, what do they see, and what sense do they make of it?
