Class Experience

In Course 1 of All About Cryptography and Codebreaking, students meet to learn about the history of wide-ranging topics such as basic secret writing, (steganography), substitution and transposition ciphers, algorithms, frequency analysis, historical events, spy networks, gadgets, and applications such as letter locking, nomenclators, and the Vigenère Cipher. Live lessons will be offered once each week and may include descriptions of an experiment or practice activity. Topics in Course 1 start out with very elementary concepts and activities as delineated above, but a basic knowledge of algebraic concepts is helpful as the material advances quickly.

Learning Goals

Schedule of Topics:	

Lesson 1 - Hidden Writing and Transposition with Basic Gadgets
Lesson 2 - Letter Locking and Cryptographer's Challenge!
Lesson 3 - Cipher Algorithms and Cipher Symmetry
Lesson 4 - Substitution Ciphers and Cryptographer's Challenge!
Lesson 5 - Introduction to Cryptanalysis and Transposition
Lesson 6 - Codes Words, Text-based Ciphers and Cryptographer's Challenge!
Lesson 7 - The Nomenclator and the Vigenère Square, Alphabets, and Letter Frequencies
Lesson 8 - Homophonic Substitution and Cryptographer's Challenge!

The interdisciplinary nature of learning is a core component of this course as virtually every subject matter is included: math, science, social studies, literature, arts, computer science, engineering, agricultural science, etc. Significant people and events will also be noted.

Cryptography is one of the best avenues to explore the intersection of a wide variety of subject matter from the standpoint of a student's particular interests, developing important lateral thinking skills and even digital literacy skills that will affect them for the rest of their lives. 

I have been a foreign language and civics teacher and professor for more than 20 years and a life-long Mensa member. As a child, I led more than my fair share of secret clubs with secret writing growing up. As a mom, one of my standard tactics at keeping my children busy was developing secret codes on the fly while waiting for dinner or on long road trips. And as a former college vice president of academic programming, (i.e., developing and updating degree programs), I worked on the first ever Cyber Security degree for a military college and supervised the development of the online courses to accompany it. Additionally, I attended meetings of the founding National Cyber Education Project Team working to align cyber standards nationally (U.S.) and also supporting the conversion of signals intelligence to cyber security expertise. And on a side note - I took my first coding class in the 1980's in a fourth grade gifted course, and I have been coding ever since. (I am still friends with that teacher!) 

I understand that modern issues of security and technology are more than just coding, though. Overall, they require logic, ethics, psychology, and a broad understanding of historical and future capabilities in a wide variety of fields. I also appreciate far-reaching implications of linguistics and computational linguistics in many areas, such as the arts, (e.g., languages in Game of Thrones and Star Trek), sports, (e.g., surveillance and espionage in competitions), healthcare, (easy access vs. right to privacy), and artificial intelligence, (algorithms and neural networks). 

And developing and solving hidden messages is really fun, no matter the method!

While I have designed this course to be a paced course, it offers flexibility to work at a learner's speed within the weeks to accommodate students' learning preferences and schedules.

See below for student responses to the question: "How did your teacher communicate with you and how frequently?"

(Note, student grammatical, spelling, and punctuation errors are preserved.)

"My teacher talked to me often, she helped me alot [sic] through out this course. She would keep me updated, give me tips and helped me if i [sic] was stuck, she also would say good morning and things like that, i [sic] know its [sic] not relavant [sic] but i [sic] thought that was really nice."

"She would always end with have a good day and a lot of teachers don't do that."

"YES. She was great. Best teacher as far as communication that I have had while doing online classes."

"She sent us tips and tricks and responded on time to any questions or concerns."

"I would ask her questions about the guided practices and grading. She would update me on assignments I didn't finish."

"She went in depth to answer my questions in a timely manner, and never made me feel like the question was dumb to ask. she [sic] also reached out to me with things i [sic] could to to do better understand the lesson and help my grade."

"This was my first time taking an online course. I was really scared and worried it would be hard but it wasn't. i [sic] rarely ever had technical issues. My teacher helped me and explained every question i [sic] had. My teacher made sure i [sic] was always on task and assisted me with tasks i [sic] should complete. Overall my experience was great , and i [sic] would recommend this class."

"I was able to learn things that were supposed to be covered in [an earlier course] in school but my teacher didn't cover it well. The communication between the teacher and students was well oriented and it would be hard to misunderstand the messages she sends. I enjoyed this course!"
