Computing Systems: Devices
During this time, students can compare how they use computers in their lives. Use Slide 4.
Jigsaw: Students are split into groups with one member assigned to each computer. Working individually, each student learns about his or her computer and presents it to their group. Next, students gather into groups divided by type of computer. Each member presents again to the topic group. In same-topic groups, students reconcile points of view and synthesize information. They create a final report. Finally, the original groups reconvene and listen to presentations from each member. The final presentations provide all group members with an understanding of their own type of computer, as well as the findings that have emerged from topic-specific group discussion.
There are organizations that provide computers for communities around the world. What do you think they have to consider when selecting computers?
Example: There is a community in the mountains of Peru that have to use electricity generated from a small personal windmill What kind of computer would this community need?
GPIO (General Purpose Input Output) Pins Pins on a microcomputer or microcontroller that can be programmed to send or receive electrical signals. They can be connected to almost anything (such as buttons and LEDs).
Raspberry Pi A small, low-cost microcomputer. Together with the Raspberry Pi OS, a special operating system, it can do many things that a full-sized computer can do.
Jumper Wires Wires used to connect from the GPIO to the breadboard. Jumper wires can have different kinds of connections on their ends, such as plugs, sockets, or alligator clips.
