One of the most valuable benefits of homeschooling is the ability to be flexible. This flexibility allows homeschoolers to dive deep into their children’s interests and to employ teaching methods that are best suited to their individual student. Among the countless instruction options are online courses. Many homeschoolers incorporate at least one online learning opportunity into their classroom.

Choosing an online homeschool program can benefit homeschooled students by giving them experience with other instructors, different teaching styles, and unique goals and expectations. Other benefits include accessing expert instruction in certain subjects and establishing good independent study habits.

STEM-based subjects lend themselves especially well to online learning. Rich with online resources, the technical nature of science, technology, engineering, or math, especially at higher levels, make these topics excellent candidates for supplementing traditional learning methods with virtual classes. Here are some of the top choices for online homeschool curriculum for STEM.
