Horizon Academic (HARP) is a trimester-long online research program, designed for high school students who aspire to conduct undergraduate-level research. The program aims to help students refine their interest in a specific academic subject under the individualized guidance of a professor from a globally renowned university. Students can choose their own field of inquiry within one of the 15 subjects that Horizon offers. In terms of curriculum, participants are expected to develop a unique research proposal and, over the course of a trimester, complete a 20-25 page research paper. To support students in this process, Horizon provides instruction on foundational knowledge in the research subject, assistance in refining research questions, advice on research stages and conduct, familiarization with common methodologies, and support in the writing process via a Virtual Writing Center. Horizon Academic is completely online, allowing students to work on their research paper after school, during the weekends, or over the summer. Instructors, who are often PhD or postdoctoral researchers in their respective fields, offer up to 20 hours of one-on-one advising sessions. Horizon also provides a comprehensive orientation to familiarize students with the teleconferencing software and online submission systems used in the program. Certain subjects at Horizon have formal prerequisites, such as AP Chemistry for Protein Biophysics, AP Calculus A/B or equivalent for Advanced Theoretical Math & Knot Theory, and one year of Calculus and high school Physics for Fluid Dynamics. Upon completion of the program, students will receive a certificate and a grade report based on a university grading rubric. They are also expected to gain a deeper understanding of their chosen subject, improve their writing and interpretation of academic journals, and perhaps even change their worldview. Exceptional work could lead to letters of recommendation or outside recognition through competitions, science fairs, or academic journals.
