OER Project world history curriculum
by OER Project (website )
High-quality, inquiry-based digital history curricula including Big History and World History Project, provided entirely for free.
Best Fit For
Secular homeschoolers looking for high-school level rigor, gifted learners who enjoy interdisciplinary connections, and families on a budget who have reliable internet access.
Not Recommended For
Families seeking a religious or Young Earth creationist worldview, students who struggle with screen-based learning, or parents who want a 'grab-and-go' workbook-style curriculum.
What Reviewers Say
The OER Project is widely regarded in the homeschool community as a 'hidden gem' due to its professional production quality and $0 price point. Reviewers across platforms like Cathy Duffy and Reddit consistently highlight the high quality of the videos (often featuring experts like John Green) and the 'Big Picture' framework that connects history to science and sociology. However, because it was originally designed for traditional classrooms, a common critique is that many activities are group-based and require creative adaptation for a single student. While the content is academically rigorous (particularly the AP-aligned World History Project), some families find the digital-only nature and the sheer volume of resources overwhelming to navigate without a pre-set schedule. Secular families appreciate the evidence-based approach, though those seeking a religious perspective will find it strictly secular, particularly the evolutionary focus of the Big History Project.
How It Works
A typical week begins with the parent logging into the online teacher dashboard to select a unit and choose which activities to adapt for a single student, as many were originally designed for classrooms. The child spends 45 to 60 minutes daily on the platform, watching professional videos featuring experts like John Green and practicing the 'Three Close Reads' method to analyze historical articles. Most learning happens at the computer, but parents often print out 'Claim Testing' worksheets where the student must decide if a historical statement is reliable based on evidence. By the end of the week, the child usually completes a writing assignment or a 'Data Exploration' activity that connects historical events to scientific data, such as population growth or climate changes.
Switching to This?
The OER Project does not provide formal placement tests; instead, the community recommendation is to choose the 'Big History Project' for middle school (grades 6-8) and the 'World History Project' for high school (grades 9-12). Families can easily start mid-year because the curriculum is modular, allowing you to jump into a specific era like '1750 to the Present' without completing previous units. If you are switching from a traditional textbook program, expect a significant shift away from memorizing names and dates toward analyzing global patterns and 'Big Pictures.' Parents should be aware that the transition requires more active facilitation to modify group-based projects into solo assignments that work in a home setting.

Reviews We Consulted
Highly recommends the curriculum for its academic depth and critical thinking focus, though she notes that the classroom-style pacing requires adaptation for a home setting.
"One of the most refreshing things about OER Project is that it doesn’t treat history like a list of names and dates to memorize. Instead, it focuses on big-picture thinking, global connections, and historical reasoning skills."
Recommends the courses for students who struggle with reading comprehension because the assignments include heavy graphics and allow parents to adjust the Lexile level of the readings.
"Also the OER Project courses on World History... includes a lot of short (usually 2-3 p) readings with lots of graphics... anyway, the advantage of their readings is that you can adjust the lexile level for many of them. It includes quite a range of lexile levels."
Values the curriculum's sensitive and nuanced treatment of scientific topics like evolution, suggesting it is a strong, accessible choice for secular families seeking a multi-disciplinary approach.
"As a secular homeschooler, I appreciate how the project navigates topics like evolution with sensitivity and nuance, making it accessible to diverse perspectives."
Praises the curriculum as a high-quality free resource and highlights the exceptional teacher support, including webinars and guides, which is rarely found in non-paid programs.
"One advantage of OER Project is that it provides a level of teacher support that is unheard of in free curricula. Teachers can access free teaching guides, teaching tips, connect with other OER Project teachers, and webinars."
Highlights the program's ability to engage students who typically dislike history by framing the subject through "thresholds of complexity" and personal self-knowledge.
"The purpose of Big History is to help us comprehend our place in the universe. With this link between total history and self-knowledge, it’s no wonder that teens find it so engaging."
Describes it as a superb resource for those seeking a skills-based curriculum and notes that the flexibility of the materials allows for easy mixing and matching of historical periods.
"The OER Project is a superb resource for teachers looking to implement a skills-based curriculum. The flexibility of the courses means that you can mix and match materials to suit virtually any periodization."

How This Compares
Compared to Story of the World, which uses a narrative, storytelling approach for younger children, the OER Project is a strictly academic and secular program that treats history as a rigorous social science. When weighed against Pandia Press (History Odyssey), OER Project offers much higher production value with its integrated video library, whereas History Odyssey relies more on external living books and encyclopedias. Parents choosing between OER Project and Khan Academy will find that OER provides much deeper inquiry-based activities and writing coaching, while Khan Academy is better for a self-paced, multiple-choice survey of facts. Compared to Notgrass History, OER Project is a 'hidden gem' for secular families seeking an evidence-based perspective, as Notgrass is deeply rooted in a Christian worldview and includes Bible study. Finally, unlike Sora Schools or other virtual programs, the OER Project is a resource library rather than a full school, meaning the parent remains the primary teacher and administrator rather than an outside instructor.
