This week saw a Duluth high school go on lockdown because of a threat received by authorities. School social workers across Minnesota say with campus safety still a big priority, they're carrying out approaches to make their environments less ominous and more welcoming.

The latest threat follows last month's nationwide social media scare on TikTok, as well as a deadly school shooting in Michigan.

Sarah Mages - licensed social worker at the St. Peter Middle School - said students have increasingly dealt with more anxiety over the past couple of decades, with threats of violence playing a part.

She said emotional connections between staff and students are important.

"We've just found that if there's that connection," said Mages, "kids are able and willing to talk to those adults because they feel like they're cared for."

Her district has conducted surveys with high-school students and fifth-grade students, asking if they feel supported by at least one adult in their building. In both surveys, three quarters of students said they do.

Social workers in other districts say home visits and crisis-intervention teams are also helpful approaches that complement standard security measures.

Prior Lake High School Licensed Social Worker Nancy VanHorne said social media messages often blend the outside world with campus environments.

If those scenarios make a student not want to come to school, her staff might visit them at home to make them feel reassured or accompany them on campus.

"You know, I had a student come in before students got here one morning," said VanHorne, "and we kind of walked the building and we talked through some anxieties she was having."

Kathy Kimani is the director of the Office of School Support for Saint Paul Public Schools. She said de-escalation efforts are important when trouble arises.

But she said there are other important ways to foster a safe environment, including social and emotional learning.

"We might do things like implement some restorative practices," said Kimani, "which would start off as students actually sitting in a circle, building community, getting to know one another. "

All three of these professionals, members of the Minnesota School Social Workers Association, said the pandemic has added to the anxiety students are feeling.

New research suggests Tennessee's system for rating a teacher's effectiveness by observing them in the classroom may not be equitable - at a time when public schools are struggling to boost teacher diversity.

Vanderbilt University researchers analyzed data from the first eight years of the classroom-observation system, and found Black and male teachers in Tennessee consistently received lower scores than white and female teachers.

Study co-author - Patricia and Rodes Hart Professor of Public Policy and Education at Vanderbilt University Jason Grissom - explained that race and gender gaps remain, even when comparing similarly qualified teachers.

"Even when they had the same experience levels and education levels as their white and female colleagues," said Grissom, "and when their students achieved similar test scores and were similar on other outcomes."

While more teachers of color are being recruited than in previous decades, districts trying to diversify their staffs continue to struggle with high turnover rates, lack of mentoring and preparation, and inadequate teaching conditions, according to the Learning Policy Institute.

Grissom said the race gap appears to be driven by several factors, including the racial makeup of the school's faculty and the observers, and the types of students who tend to be assigned to Black teachers.

"But partly because they teach students who come into their classrooms with greater challenges," said Grissom, "it seems to be that's one of the drivers of why their observation scores are lower."

Grissom said he believes school districts should be aware of these factors in order to improve the fairness of the system.

"School districts, I think," said Grissom, "have an obligation to take a close look at their scoring processes and the scores that they're giving, ensuring that those scores are accurate."

Research indicates having a teacher of color correlates with improved academic performance in Black and Brown students, including higher reading and math test scores, graduation rates and college plans.

Colleges and universities typically provide in-person programming and supports to strengthen bonds between students and build a sense of community. But the pandemic curtailed both in-person learning and campus-wide events.

As students return to classrooms, new research shows what schools might do to rebuild those bonds. Ithaka, a nonprofit that works to improve educational opportunities, encourages higher-ed institutions to step up community-building.

Research by Emily Schwartz - senior program manager with the Ithaka S+R's educational transformation team - found a greater sense of belonging can improve a student's academic experience, and boost their chances of graduating.

"A lot of students that are entering college now," said Schwartz, "they haven't had the chance to have the in-person experience, and without those roots of the connections made in person, I think it can be very challenging."

Schwartz said schools need to make sure they're listening to students and student leaders about what they need to succeed in a post-pandemic world.

Undergraduate enrollment at colleges has fallen 6.6% since fall of 2019, according to the National Student Clearinghouse Research Center.

For most college students, the pandemic eliminated one-on-one advising appointments, career development workshops and mentorship programs. Schwartz said that's been especially tough on students from historically underrepresented backgrounds, lower-income students and students of color.

She said she thinks it will be important, particularly for community colleges, to offer more diverse activities and programs to rebuild a sense of community.

"If you're offering some sort of activity that's at 7 p.m. every night, and a student has a family and kids, that time might not work for them," said Schwartz. "So, having variety in programming, I think, is really important."

She added that the pandemic also magnified existing societal inequalities in access to technology, including disparities in access to broadband and digital devices.

The Chicago Teachers Union held a day of action yesterday, outdoors and in their cars, in an effort to safely push back against returning immediately to in-person classes, with the surge of the Omicron variant hitting the area hard.

Teachers in the union have proposed a return to online learning until Jan. 18, to avoid a major outbreak. Mayor Lori Lightfoot has so far opposed returning even short-term to online learning, saying it's safer for kids to be in-person in school for social, emotional and developmental reasons.

Jesse Sharkey, president of the Chicago Teachers Union, said the educators want that, too.

"We've been in schools during a pandemic trying to educate children, and that's where we want to be again," Sharkey asserted. "But we're asking for some basic commonsense safety measures."

The union is asking for more support from the city for testing and personal protective equipment, and they say there should be procedures in place for outbreaks in schools. Monday marked the fourth day of cancelled school.

Chicago currently has an opt-in testing programs for public school students. But the union said not enough people opt in, and it would be better to have an opt-out program.

Sharkey contended when it comes to controlling outbreaks in schools, if too many educators, staff or students are out due to COVID, it is worth temporarily returning to remote learning.

"If you say school's all good and half the students don't show up, you're not doing any learning for half the students," Sharkey argued.

He pointed out if 25% of staff, 30% of elementary school students or 25% of high school students are absent due to COVID, it should be a signal for individual schools to go online, and allow cases to slow.
