Dr. Bob Brown, a retired KSU faculty member, can present the following at schools or other locations in the Atlanta area. For dates, please see his availability calendar. These presentations geared toward middle school and high school students, but can be adapted for other audiences, including elementary school students. Contact Bob at Bob.Brown@Kennesaw.edu for details or to schedule a presentation.
Bob is a Raspberry Pi Certified Educator.
Binary numbers: This is a single 50-minute (about) presentation that introduces binary numbers. It was designed for grades 6-10, but has been presented successfully to third-graders. The session outline and objectives are included in the teacher notes. If I present this, I will furnish a set of binary counting cards for each student, but we ask schools to duplicate the handout. I have fun presenting this, and I hope you'll invite me to do so, but I've packaged it into a teachers' kit that will let teachers present it independently with minimal pre-work.
Boolean Logic: Kat's Cat Checker: This is the logic-only part of the Digital Logic series, condensed to a one-period presentation. Katherine, Kat for short, is headed to Hogwarts, and uses logic to specify the ideal cat to take with her.
Careers in computing: This is a 30- to 50-minute presentation, depending on the time available, in which I discuss a number of careers in the computing field and end by suggesting that students also consider becoming a college professor.
Coding fundamentals: This one is still under development; help me work on it. I'm working on a presentation of about 15 contact hours for a summer camp and something much shorter. I'm looking for a school to work with me on the shorter version.
Coding with Blockly: Blockly is a visual programming environment developed by Google. I haven't developed any instructional material for it, but I'd like to if there's a school that wants to work with me. Doing this thoroughly would probably take several days of instruction.
Cryptography, introduction: A single 50-minute session that introduces substitution and transposition ciphers, beginning with the Cæsar Cipher. Students decrypt a message encrypted with the rail-fence cipher, then create a keyword substitution cipher. The presentation is available as a narrated-slide video. The accompanying handout is available as a PDF.
Cryptography, public key: A single 50-minute presentation that demonstrates the workings of modern public key cryptography, including digital signatures. This one is all lecture, with no classroom activities, and so is best suited to grades 10-12. There is a take-home exercise in which students generate their own public/private key pair.
Digital logic: I've presented this several times with refinements after each. It shows students that there's no magic in computers. There is an outline and objectives document available; I am very willing to adapt it to your curriculum. Handouts for all three days are available to download, and there's a video of day 3. Students need a basic understanding of binary numbers. This might fit best in grades 8 to 12.
Information Security: This is a series of three presentations with a target audience of grades 7-10. It is probably best to do these once a week or every other week for three or six weeks rather than all at once. The three sessions are Information Security Fundamentals, Encryption, and Threat Analysis. There is more detail in the outline and objectives.
Raspberry Pi: What we can do depends on the school's objective, the equipment available, and the time available. If you have Raspberry Pi equipment, I can help your teachers get ready to use it in the curriculum. I can work directly with students to get them started building Raspberry Pi projects. I can help your school start a Code Club and provide some assistance in the operation of the club. If the Raspberry Pi is new to you, it's a $35 computer that can be used for making physical projects. The $35 is for a bare computer; you will end up spending $80-200 per pair of students to equip a Raspberry Pi lab. I've prepared an annotated shopping list to help you get started. The Raspberry Pi Foundation has more details.
Need something else?
I am very willing to prepare new material to suit your needs or curriculum. Contact me and we can probably work something out. I'm also available to help with curriculum development, professional development, and the development of learning objects. Contact me at Bob.Brown@Kennesaw.edu to work out the details.
There is no fee for any presentation, but we do ask that schools duplicate any handout material that may be required. When I present at a school, a teacher must be present at all times and be responsible for classroom management. The presentations listed are designed for a room with a projector, but can be presented without one if you give me notice.
