This summer, I reprogrammed the Scribbler 2 Robot from Parallax Corporation to be a physics apparatus. (I intend the robot project itself to be the subject of a future blog post.) This lab practicum is the student’s first opportunity to program a robot themselves. Each group is given two robots, one programmed in advance by me that students studied in their first robot lab, and a second one which they must program themselves through a position vs. time graphical user interface. Students must understand how a position vs. time graph describes motion in order to get the robot to complete the assigned task.
In physics modeling instruction, the constant velocity particle model begins with a paradigm investigation of the motion of constant-speed buggies. This summer, I reprogrammed the Scribbler 2 Robot from Parallax Corporation to be a physics apparatus , and this was my first chance to use them. (I intend the robot project itself to be the subject of a future blog post.) For the robot lab, I programmed the robots to have speeds from 10cm/s to 18.5cm/s, but all to go 150cm before stopping.
a community or other unity that is an epitome of a larger unity (Meriam Webster Dictionary)
I use the word microcosm to refer to a classroom of students acting as scientific investigators to construct and deploy the laws and concepts of physics. The classroom is a microcosm of the larger scientific community.
I also use the word microcosm to refer to the use of technology to create a limited physical world, within which students can explore independently and figure things out for themselves.
