Wave videos

by Today is a Good Day

7th graders in my Tech. class are making videos. I am working with the science teachers in my building on this project. Each pair of students has picked a sub-topic under “Waves” which they are studying in science right now. They are making 2-4 minute videos to present back to their science classes.

The first task was for them to brainstorm by making powerpoint slides for each section of their videos. Although I showed some similar videos from mathtrain to give them ideas the students had a hard time understanding what I was asking them to do. I was throwing a lot of new stuff at them as I gave them multiple tools to use (my wikipage of resource for the students). We have Camtasia Studio 7 on all of the computers in my lab thanks to a great grant from TechSmith. So the students will put their end product together in Camtasia.But they have many options to make it with including screencasts of PowerPoint, my Pulse pen, online whiteboard, webcam, microphones, music, and even Stykz. I encouraged students to use multiple methods of presenting which they will combine in Camstasia. I will write more about some of these tools after students finish, but I will just mention the online whiteboard is a very nice tool that students can email to each other and both write on the same space at the same time.

We have used this opportunity to talk a lot about creative commons and open source. This topic is very foreign to them. For their entire school career they have gotten full credit for plagiarizing from their textbook by “cutting and pasting” the answers to the questions at the end of the chapter. Then teachers get mad at them when they do the same thing on-line. We spent considerable time talking about copyright and the rights of artists. I also demonstrated repeatedly how to use tools like Compfight.com and Flickrstorm to search Flickr for creative commons images. But Flickr is not a good source of pictures about many of the types of waves they were researching so I also taught them how to do a creative commons search in Google and used usa.gov and wikimedia commons which have more scientific images.

We also talked about slide design in Powerpoint. I showed them how to make a set of slides based on interesting pictures instead of text-heavy with bullet points, clip art, or animations. All of this took much longer to get started actually making the videos than I anticipated, but I think we have learned about many important principles along the way. This week they will get busy making them and hopefully have some great presentations by the end of the week.

Girls in Technology

I just finished a nine-week, 7th grade technology class. It was a great bunch of kids. They experimented with straw rockets, constructed polygons in Geometer’s Sketchpad,made pneumatic-powered devices, created egg drop vehicles, experimented with Lego Robotics, designed with Building Homes of Our Own, and ended with a GPS unit.

Often times my tech. classes are dominated by boys, but this class was about 50/50. In particular I had a group of girls who are model students as far as behavior and honor roll grades. They did every assignment with great attitudes. But when I asked the students at the end of the quarter about what their favorite and least favorite part of the class was,they did not like anything that we did. I got lots of “boring” comments. Now some of this could be chalked up to the end of the year, I just want to be out of here feelings, but it does bother me that my class seems to be loved by boys and only tolerated by girls. This is not the first time that I have received this kind of feedback from female students.

So what can I do differently? How can I get more girls (there are some who like my class) excited about technology, science, and engineering? Do I need a different kind of project or a different approach to my current ones?
