First of all --- we need to use the proper terminology -- the subject is "Social Studies" now. "History" is a term of the past.
The best explanation I have found in a short search is in Ed Week. See the section with the bolded - "Rather than memorizing names and dates".
============================================================================
The Common Core Standards in social studies include a focus on social studies skills rather than focusing on the Jeopardy-like social studies classrooms of the past where students memorized dates and names. The new standards place a special emphasis on students understanding a variety of perspectives when studying various time periods throughout history. In addition, the Common Core Standards require students to gather evidence to support claims throughout history, and in doing so create their own understanding of the world. This approach is very much in line with the ELA Common Core Standards and even the Next Generation Science Standards. The Common Core Standards in social studies mean that students investigate people, places and historical events, gather evidence from primary source documents, and construct their own knowledge about the past, based on their findings. In doing this, students learn to source documents - becoming detectives searching for history, rather than students who simply consume one version or story about history.
Under the Common Core Standards, a social studies classroom will look more like a collaborative space, where students might be debating about what they see in a historical image, or evaluating the words in a letter written by a WWI soldier. Rather than memorizing names and dates, students are now searching for reputable sources of information online to gather evidence about what actually happened during specific time periods and understanding the various sides to our world’s ongoing story. In short, students are interacting with information rather than simply consuming it. When students have a question about history, under the Common Core Standards, they should no longer feel that the teacher is the only person who holds the answer--they are now encouraged to search for the information, locate reputable sources, understand the information in context, and share their findings with their peers. The Common Core Standards in the history classroom also mean that students are writing and reading differently than in the past. Rather than writing a research paper about a historical topic, students might be asked to investigate the perspective of various people and write about those perspectives, supporting their writing with evidence from primary source documents. When students read about history, they read with a purpose (to answer a question, or locate evidence).
Finally, students in Common Core social studies classrooms are now being asked to investigate a topic within a time period and create something that shows what they have learned - whether it is a piece of writing, a video clip, or an interactive image using various technologies.

As a parent with kids in school the way it works here is in middle school they have social studies which is sort of a broader survey of history, culture, religion, current events. In high school is when they begin History class proper. Three years History 1 & 2 (something like world history and US history) then a choice of 2 half year electives.
Education is a state to state thing. I live in a left-left state and it’s still regular history here.
