LIVONIA, Mich. — A racially offensive history lesson involving slavery has a Detroit mother outraged and calling out her daughter’s school. The parent Livonia, Michigan says she’s speaking out so no other child has to go through a similar situation. Now, the school is issuing a statement of its own.The lesson came during a seventh-grade social studies lesson at Frost Middle School in Livonia that left student Jade Holt disgusted. “It was weird and uncomfortable,” Jade said. She said her course on the history of slavery included a question that read: “A slave stands before you. This slave has disrespected his master by telling him you are not my master. How will you punish this slave?”“I read the question and typed my answer. It was, 'there will be no punishment because I do not believe in slavery,'” Jade said. “I never want my daughter to feel that way again, the way she felt this morning,” Jade's mother Jaala Holt said.She believes the teacher also isn’t the only one to blame. “Everything has to be approved before it’s given to the children. So, for whomever approved this inappropriate question for seventh graders, I find it asinine for me,” Jaala said.A school spokesperson released the statement below, which read, in part:“Concerns from a parent were brought to our attention this morning, and we have reviewed a social studies assignment given to three classes of our seventh-grade students. We recognize the assignment in question was not constructed appropriately, as we believe in the importance of approaching topics of slavery in any era of world history with the utmost care and consideration.”The principal hasn’t said if anyone has been disciplined. At a minimum, Jaala Holt wants teachers to undergo cultural sensitivity training.This story was originally published by WXYZ in Detroit. 1825

Logging onto social media platforms can provide joy for many people. Grandparents can see pictures of their grandkids. People can connect with peers or catch up on topics they follow. But in the same social media feeds are posts that seem normal but pose a danger that isn’t always obvious.Misinformation isn’t always a clearly false statement of fact. It can be one subtle change that twists the truth. Experts say misinformation is spreading faster and easier than ever before. They’re hoping to address the issue by asking why people believe and share false information.Researchers say the process people use to process and share information, particularly on social media, can help provide some answers. Studies show people tend to use cognitive shortcuts when they decide what to share online.For a person sharing a particular article or picture, those shortcuts involve asking themselves:Is the content consistent with what they have shared before?Is the content consistent with what most others share?Does the content come from a credible source?Researchers think manipulating those factors could be key in getting people to share posts with misinformation and increase its organic reach.Experts think age is another factor in how misinformation spreads online.One study found people 65 and older shared seven times more misinformation on social media during the 2016 election cycle than the youngest age group studied. Researchers say a lack of digital media literacy in seniors could help explain the gap. They’re now pushing initiatives to increase literacy rates.There’s one way researchers found to help stop people from sharing misinformation and that’s a simple reminder to consider the source and accuracy of information before sharing. 1758
