Teaching the subject of world history is a very arduous and arduous task. There are many problems associated with teaching a subject like world history. There are disagreements and conflicting ideas from different groups about how the subject should be taught. States all have different standards, some of them wide-ranging, regarding what will be covered under the umbrella of world history. Other issues, such as time, resources, and whether teachers are actually prepared to present a subject like world history to students, come into play to determine how difficult it is and the problems involved in teaching world history. One of the main problems with teaching world history is that there is no consensus on how it should be taught. In an article by Ross E. Dunn titled Many social studies teachers are well versed in American history but not so much in world history. This may be because American public schools emphasize U.S. history over world history and that is what they have been taught, known, and are most familiar with. It may also be that these teachers have more interest in U.S. history than world history. In both cases, time and money are determining factors in preparing to teach world history. Many history teachers who are not experts in non-US history do not have the time, resources, or funding to educate themselves on world history. In regards to training educators, I don't think the university curriculum places enough emphasis on world history, as in my experience what you learn about world history is limited and very few courses are required to graduate and be qualified to teach a subject as wide-ranging as the history of the world. Funding is an additional problem as the Department of Education allocates much more to U.S. history than to world history with figures of $680 million for U.S. history professional development and nothing for history of the world. It's no wonder there are problems teaching world history if there is no funding and not enough competent people to teach
