Fellow Tian Gao with undergraduate student Sam Seifert demonstrated their  Number Line and Equation Handler software during the GK-12 Mid Year Workshop. Students use their hands to move numbers in an equation to solve for X. GK-12 teachers were very excited about the product and were anxious to help further develop the product in their classes.

 

 

Last Semester, Summer and Beyond…

Here are some of the highlights from later half of the semester:

1. Skateboarder software: we brought kids to computer lab for an exploration on the Skateboarder software. It is basically a software where user uses mathematical functions to define the path of a skateboarder will travel. After we explained some of the basic concepts and a set of concrete instruction at the beginning, we let students to play it around. The results are pretty amazing. some girl was able to put a bunch of skateboarders inside a circle path and definitely won the “Who can keep skateboarder moving longest” competition. While some of the math concepts are beyond 7th grade, like some of sine and cosine curve functions, kids are eager to explore them and I had the opportunity to explain them.

2. IBM Watson Supercomputer: due to the supercomputer fever, I decided to show some clips introducing the IBM Watson and how it works and beginning of the actual jeopardy competition, time-allowing. Some of the students heard of it, but most students had vague, if not none, knowledge of it. It was a fun class that I was able to explain the basic difference between IBM Watson and Google Search. It was also related to my research and I actually went to a talk about this supercomputer, and as a result I actually know a lot about it and we were able to discuss how it actually works. It was also fun to watch these students watching the clips in admiration. I wish there is a new breakthrough technology every now and then so I can show them to the students.

3.  Geometry and Pythagorean Theorem: geometry is one math topic where students can actually visualize  the shapes and volumes. In addition to some activities that Julia usually uses to teach class, we found a cartoon book about the life of Pythagoras. Although it is mostly fictional, it inspires kids on how Pythagoras discovers the concept of Pythagorean Theorem. Kids take turns to read part of the stories and it was  a great integration of  English and Math. After the story, we asked students to show the Pythagorean Theorem by reorganizing the several pieces of 2 squares to form a larger square. It was fun. For honor math class, I challenged them one more step and showed the easiest proof of Pythagorean Theorem. I was aiming for a few students to be able to follow it but a lot more asked a lot of questions about the proof that is far beyond what they have learned so far. I was surprised and really glad that they are actually interested in the proof.

4.   A Real Demo of Math and Engineering: after several hectic weeks preparing for the state exam, I was finally able to give a great example on what I wanted to do for a long time: to show that Math is important everywhere. I was looking for something that students are interested and can be used to show the math going into the design and everything else. Taking suggestion from Ron, I contacted RPI Public Safety Outreach Program and an officer, David Jordan, nicely agreed to do a live demo on how to use a defibrillator in Doyle Middle School.  Then I explained some of design decision using 7th grade math, which is quiet a challenge to say the least! It was exciting class to see kids want to learn how defibrillator works and why it works. The assumption that defibrillator would attract their attention because girls want to help people while boys like things that can “shock” people is sound! Some kids from other classes also joined the presentations. Overall, it was a great success.

 

Summer

during research week, I gave a presentation on the my research and the software we have been developing. Here is a screenshot in current stage:

Julia and I discussed the potential usage of the motion tracking software. We decided to spit the program into several and each covers a specific topics so we can do more with it. I am working to include more gesture, especially fun gestures, in the software so kids will like it. Stay tuned as we work hard on it!

 

That’s all for all. Looking forward to the new semester!

A New Semester

A new semester, a new start.

First of all, I should say I should post here more often. Sometimes it is just a bit too much to juggle between middle school, homework, research and sleep. Anyhow, it has been fun to go to schools and it is the most exciting and fun part of my day, energizing the rest of day. I was particularly excited when several kids cheered to see me and called me “awesome”. They should do it more often J.

At the end of last semester, Julia and I were able to bring Microsoft Xbox Kinect to class and let kids to experience frontier of technology. The topic that week was Proportion, so we designed a worksheet that basically asks some proportion questions involving games, for example “If you can score 15 points in 10 minutes of Kinect Adventure, how many points can you score in 30 minutes at the same rate?”. Kids who finished the questions first got to play Kinect first, although everyone got to play it in the end. They were really excited and challenged each other to beat their own high scores. In addition, we also used NUMB3RS to explore the famous problem of “Rice and Chess”, focusing on the topic of exponential growth. We read them the story of “Rajah’s Rice”, burrowed from school library, and I wanted to challenge them by explaining how to do arithmetic sum on such sequences. Although not everyone could understand it, they were able to follow it. I feel we should expose them to harder problem sometimes so they know there are more stuff than the material they can get a good grade on.

Since this semester starts, kids have been busy with their own end of quarter and some standard tests. Moreover, the honor class got to take a state-wise math competition this week. I acted as proctor for once! However, the questions are difficult and I hope them to do well and win! IN term of math topics, students have learned some probabilities and been working on graphing now, including bar graph, histogram, circle graph and all other kinds of statistic graphs. They also learn to use protractor to measure angles. It has been a lot of hands-on and 1-on-1 teaching. Students got the concepts fast, to my surprise!

Since it is graph related, we want to use Skateboarding software to further challenge students’ ability. Due to scheduling in reservation of computer lab, we will not be able to do it until March. In the meanwhile, I want to show some part of IBM Watson: Machine vs. Man Jeopardy to students and show some videos that explain how it works. I know it is a hard concept but it is highly relevant and can definitely generate a lot interest!
