Alexandra Konsur-Grushinski has spent time in education teaching both students and adults how to embrace technology, STEM and Computer Science as tools for learning. Working with all sized learners (PreK to adults), she aims to demystify CS concepts as well as get students to engage in learning enthusiastically. She is passionate about aviation, electronics, robotics, programming and 3D design. This passion is illustrated by her management of projects developed for and utilized in iCreate STEM, a technology-focused STEM/CS program out of NEIU 19 Technology Department and her leadership roles in NEPA STEM Ecosystem and PA Statewide STEM Ecosystem (PSSE).

Session description

Explore different ways in which cryptography can be used to teach math concepts. After hearing a usage case, you'll engage in exploration around different types of ciphers and the mathematics content and best practices surrounding their use.

Purpose & objective

The purpose of this session is to explore different ways in which cryptography can be utilized to teach math concepts. After hearing a usage case, participants will engage in exploration around different types of ciphers and the mathematics content and best practices surrounding their use.
Session Agenda:
-Introduction and Statement of Purpose
-Presentation of Usage Case where Cryptography was used to improve math skill sets
-Hands on Participant Exploration of Cryptography and its mathematical concepts (3 cipher types will be introduced along with associated math skills)
-Call to Action - Group Discussion on how Teaching Cryptography can benefit students
-Hands on Participant Development of a plan to take Cryptography or other elements of Cybersecurity to their classrooms

Outline

Content and Activities with Time and Process:
-Participants will have access to introductory information around the history and prevalence of Cybersecurity in the modern world with an emphasis on Cryptography through a shared slideshow.
-In addition, presenters will share the current job growth both current and projected around careers in cybersecurity. (10 minutes)
-Participants will hear about a usage case in which Cryptography was utilized to improve mathematics skills. (5 minutes)
-Participants will engage in hands-on experiences of three types of ciphers, each addressing different skills in mathematics. Peer-to-peer interaction (20 minutes)
-Participants will use their new foundational skills in Cryptography to engage in a discussion around how they can utilize this teaching approach with students in their own districts/schools. Peer-to-Peer interaction (5 minutes)
-Participants will begin to formulate different activities and lessons in which this approach can be utilized. Peer-to-Peer interaction (time remaining)
