You can see sample student submissions, and how College Board scored those submissions, here: http://apcentral.collegeboard.com/apc/public/exam/exam_information/231726.html#anchor3
This Q&A is very useful as well: https://secure-media.collegeboard.org/digitalServices/pdf/ap/explore-student-performance_q-and-a.pdf
Students need to choose a computing innovation of interest to them, and be able to explain potential positive and negative effects the innovation has had on society, economy, or culture. Students also need to identify the data that the computing innovation uses (ie publicly available criminal records, private medical data, user generated data), how the computing innovation consumes, produces, or transforms the data, and they need to identify a storage, privacy, or security concern associated with the innovation.
According to the College Board Q&A, a computing innovation is an innovation that includes a computer or program code as an integral part of its functionality. High scoring submissions included descriptions of physical computing innovations such as Google glasses, nonphysical computing software, such as cell phone applications, and eCommerce, which relies on transactions conducted on the Internet. Something like a car is not a good example computing innovation, because one can have a car without any computers. Something like the computers and sensors used in a self-driving car would be a good example of a computing innovation, because computers and programs are essential to self-driving cars.
Students must make a computational artifact that explains the purpose, function, or effect of their chosen innovation. Computational artifacts include, but are not limited to, videos, audio recordings, video presentations, infographics, or websites. Students can create websites on CodeHS, or slideshow presentations to be used in videos on CodeHS. Students will need to use other software to make infographics or recordings, but there are plenty of free services for this on the Internet.
CodeHS does not provide a way to make an audio or video recording, students will need to use other computational tools to make these types of artifacts. We do provide a way for students to make a website, or a slideshow presentation with Google Slides right from the CodeHS website (instructions are in the project), if they want to use a website or a slideshow as part of their artifact. Students can then use other free software to create screen / audio recordings of what they created on CodeHS. They could also make an infographic with something like Piktochart.
Part of this course is teaching students to find and use computational tools that suit their purposes, so external websites that help achieve their goals are great.
Students can develop their computational artifact, and written answers to the free response prompts, in the Performance Task unit of the AP CSP course, or in the CodeHS Sandbox, but the final submission must be uploaded to the College Board AP Digital Portfolio.
