In existing CryptoClub after school programs, middle school students use mathematics to make and break secret codes. The CryptoClub website has tools for encrypting, messages to crack, treasure hunts and other activities. In this project, the learning in fifteen Crypto Clubs is extended by having the students generate tutorials that explain how they solve mathematics and cryptographic problems. The flexibility of the after school setting provides the opportunity to experiment with content and technology. Student-friendly ways to create the tutorials are developed and best practices for incorporating tutorial making in CryptoClub programs are investigated. A collection of vetted online tutorials about mathematics and cryptography created by students and teachers is to be available to all on the CryptoClub website. At least 15 teachers are to be trained to assist their students in developing tutorials. These teachers can then use this learning technique as they teach other mathematics topics. The research investigates the features of the tutorials that students and teachers consider to be appealing and easy to learn from. The kinds of mathematics problems that make helpful tutorials and promote communications skills are studied. By focusing on specific topics and using students within the same clubs as control, the project leadership can conduct a controlled study of learning that occurs on those topics and thus investigate whether the students learn mathematics from the experience of developing video tutorials. The project also considers the technology and software that facilitate the development of the tutorials and the system for online sharing, rating and sorting of video tutorials that promote the development, submission and use of the tutorials. Evaluation is done by an independent evaluator and an advisory board. Students will develop technical literacy and skills in mathematics, computer technology and communications and become aware of cryptography as a possible STEM career as well. The project deepens students' understanding of mathematical reasoning, supports their development of self-efficacy and increases their interest in STEM and STEM careers that use mathematics.

在现有的 CryptoClub 课后项目中，中学生使用数学来编写和破解密码。 CryptoClub 网站提供加密工具、破解消息、寻宝和其他活动。 在这个项目中，通过让学生生成教程来解释他们如何解决数学和密码问题，十五个加密俱乐部的学习得到了扩展。 课后环境的灵活性提供了尝试内容和技术的机会。 开发了学生友好的创建教程的方法，并研究了将教程制作纳入 CryptoClub 程序的最佳实践。 由学生和教师创建的经过审查的关于数学和密码学的在线教程集合将在 CryptoClub 网站上向所有人提供。 至少 15 名教师将接受培训，以协助学生开发教程。然后，这些教师可以在教授其他数学主题时使用这种学习技巧。 该研究调查了学生和教师认为有吸引力且易于学习的教程的特征。 研究了有助于辅导和提高沟通技巧的数学问题。 通过关注特定主题并使用同一俱乐部内的学生作为对照，项目领导可以对这些主题上发生的学习进行受控研究，从而调查学生是否从开发视频教程的经验中学习数学。 该项目还考虑了促进教程开发的技术和软件，以及促进教程开发、提交和使用的视频教程在线共享、评分和排序系统。 评估由独立评估员和顾问委员会完成。 学生将培养数学、计算机技术和通信方面的技术素养和技能，并意识到密码学也可能成为 STEM 职业。 该项目加深了学生对数学推理的理解，支持他们自我效能的发展，并增加他们对 STEM 和使用数学的 STEM 职业的兴趣。
