Creating a High School Website Portfolio is probably one of the easiest things high school students can accomplish because it is a companion to the work already completed in high school. It also allows a student to step into the role of "reporting" instead of showing off what they are doing in high school. By posting the essay for English class, or Slide Deck or video that was orally presented infront of the class in Physicas Class, or a seires of screen shots shoing a mathmatical algorithm, the student can simply deposit the artifact.
If the student goes one step beyond that and writes a not about the assignent, how long they worked on this project, and then later, perhaps at the semester, moves this artifact to the "highlighted Projects" page, then this assignment is doing what it was desiged to do.
The student could then move into the third highest level and reflect in writing, or voice recording, or YouTube influencer style and reflect on what they liked about it, and then what, why, how, they would improve the artifact if given a similar assignment again.
What does it show college recruters, internship committees, scholarship committees, and potential colleges and universities that may "Google" the student? Committment to a process such as this over a 4-year period is showing committment to almost a quarter of their existance. Maintaining a high school profesional website portfolio showcases reflection and committment, which is less common in teenagers than say a committment to a fun sport. It also contains writing samples, over time. This can show growth. Even an essay completed in middle school, grades 6 to 8, can be compared to work completed in grade 9. The middle school writing is not compared directly, but to show growth, creativity towards the assignment, ability to research topics and make connections, etc. In other words, a portfolio website should include early works, late works, and reflections coparing the assignment to itself, and highlighted growth over time.
