After several years of collaboration with the Tufts professors. Sukoiotf brought the software to the University. "The computer collects the data Sokolott said In one experiment, students study movement and motion using their own body as the subject. Students walk hack and forth in front of a small clicking black box. The hox is a sonic motion detector and is hooked up to a Macintosh comput er on the same table. As the student paces around the room, the detector measures the student's position as a func tion of time At the same instant, the Macintosh computes the students'velocity and acceleration and plots a graph on its screen. "It's your own body, and you see what it's doing.'' Sokoloff said. "That's a real teaching experience." Students are able to interpret the results of their experiments utmost immediately, and discuss with the instructor what they’ve learned. Sokoloff said studies suggest students gain u more solid understanding of the lows of physics when using computers in their experiments, for several reasons. First, students learn physics by investigating the physical world, rather than manipulating symbols 1Students spend time ana lysing a graph, Instead of the drudgery of plotting it.’ David Sokoloff, physics prolessor or ills* tissing c.onc opts ahstrnc llv , iis with trade nonal c ourses "It challenges you to make predictions while doing the experiment, instead of lust confirming the outcome." Sokoloff said Second, the immediate feedback from the experiments enc mirages students to collaborate Because the data is presented in an understand able way. students can discuss the validity and implications of it with peers, Sokoloff said Sophomore Brian Codings said the computers have helped him learn the basics. "You get a visual image both on the computer and what's in front of you," he said "It makes you think a little harder about what you're seeing Graduate teac hing fellow Ray Peini said he's found students apprec iate the speediness of the computers most "The computer does the graph right there, in 20 25 seconds," he said. "You don't have to wait lo ts minutes to find out if you need to do it again." TUESDAY s p A G H E T T I I ALL ?
