Each of the Cornell College instructors injured in a stabbing during their teaching trip to Jilin City, China are back with family or moving forward from the incident, the college said in a statement Tuesday.

Cornell College President Jonathan Brand said in the update to campus that all four of the instructors have either been reunited with family members or are continuing with their summer travel plans after being injured in a 鈥渟erious incident鈥� in a public park in the city last week.

People and organizations both in the U.S. and China aided in getting the instructors the care they needed, Brand said. He said he has been reminded through this time about how the 鈥渆xtended Cornell College community鈥� cares for each other.

鈥淲e appreciate the support from our colleagues at Beihua University, and we have thanked our state and federal legislators as well as the Department of State for their efforts to assist our instructors and their families,鈥� Brand said in the statement.

The instructors were teaching at as part of a partnership with Cornell College. The June 10 incident occurred while the instructors were visiting a park near the university, accompanied by a colleague from Beihua. A man bumped into one of them, according to Jilin City police. The suspect, who police apprehended and identified as a 55-year-old with the surname Ciu, then allegedly stabbed that individual and the three other instructors.

One of the instructors involved in the incident was David Zabner, state Rep. Adam Zabner鈥檚 brother. A Ph.D. candidate at Tufts University, David Zabner was in Jilin City as part of the partnership between Beihua University and Cornell College when he was wounded in the arm during the incident. The names of the other instructors have not been released.

According to Adam Zabner鈥檚 , his brother returned to Iowa late last week. The representative said in a statement that the U.S. State Department and U.S. Consulate in Shenyang were helpful during David Zabner鈥檚 treatment and in efforts to bring him home, as well as the offices of Vice President Kamala Harris, Sen. Chuck Grassley and U.S. Rep. Mariannette Miller-Meeks.

Cornell College has partnered with Beihua University since 2018 to bring instructors from Mount Vernon to Jilin City to teach at the university for two-week periods.

But a survey by 社区黑料 reveals the answer is more complex, that while some schools have revised their acceptance criteria based on the availability of rigorous courses, including calculus, others have not. 

Queries sent to 20 top-tier colleges and universities, many of which are recognized for their strong engineering programs, found that 11 do not require it while six strongly recommend or encourage it.

Calculus may not be a must, but it is still expected at many institutions.

looks for some applicants to complete the class if they have access to it. Likewise, , and strongly recommend or encourage at least some applicants to take the course in high school.

was alone among the 20 in still mandating calculus. In fact, the Ivy League school tells incoming freshmen that at least one of their two letters of recommendation must be from a math teacher and they are 鈥渟trongly encouraged鈥� to make that person their precalculus or calculus teacher.

Caltech dropped calculus, physics and chemistry from a list of required courses while widening students鈥� opportunity to showcase their abilities through other means, including the completion of online courses through the free .  

Ashley Pallie, Caltech鈥檚 executive director of undergraduate admissions, noted it was a significant shift for the STEM-intensive titan. The school had required a calculus course for decades, she said, despite pushback from applicants. 

鈥淓very year, we would get lots of students who would write in and say, 鈥業 was on track to take it, but the teacher isn鈥檛 able to teach us here,鈥� or, 鈥楴ot enough students signed up for the class,鈥� or, 鈥楾he class isn鈥檛 offered at my high school,鈥欌�� she said. 鈥淎nd the answer was always, 鈥楴o. We need to have the course requirement.鈥� 鈥�

But that changed when Pallie and two faculty members, who set admissions criteria, learned at a February conference on equity and college acceptance the extent to which the course is not available, particularly to low-income applicants, students of color and those living in rural areas. 

Pallie credited Melodie Baker, national policy director at , an organization that promotes math policies that support equity in college readiness and success, for sharing the information at that gathering. Calculus still has merit, Caltech faculty concluded, but should no longer be mandated. 

鈥淪o now it’s less about having taken the course and more about, 鈥楥an you showcase to us that you have proficiency and mastery?鈥欌�� Pallie said. 

MIT follows a similar model; it wants incoming freshmen to have two semesters of calculus but allows them to place out of the requirement either through outside credits or by taking an Advanced Standing Examination.

Calculus is not required for admission to any school or college, including the College of Engineering and the Ross School of Business. 

And the same holds true at , , , and Johns Hopkins. 

The explanation is simple, according to one school鈥檚 spokesperson. 

鈥淲e recognize not all high schools have a calculus course available to students, so it is not required for admission to Johns Hopkins University,鈥� said Jill Rosen.

Baker, of Just Equations, said colleges and universities should always seek to widen the opportunities for bright applicants so they can one day help solve the world鈥檚 most complex and enduring problems. 

鈥淲hen math is used as it was intended, to cultivate and develop talent rather than rank and sort students, the future of STEM looks like a microcosm of the larger society,鈥� she said. 鈥淚t looks very different from what it looks like today: It looks well-represented.鈥�

The doesn鈥檛 demand calculus for entry to any of its undergraduate programs. However, the school does prefer that students study the topic at some stage: It鈥檚 mandatory for some majors, though it can be taken at the college level. 

Still, a spokesperson for the five-college system said, 鈥淎nyone can get in without it.鈥�

For other colleges, the answer is nuanced. Neither calculus nor precalculus is a requirement for first-year admissions at the , a spokesperson said. 

The vast U.C. system, which encompasses 10 campuses and some , does, however, note that those interested in STEM, data science and the social sciences are 鈥渟trongly encouraged鈥� to consider a math course sequence that prepares them for calculus 鈥� either during high school or in their first year at the university.

Sharon Veatch, school counseling department chair at the rural Housatonic Valley Regional High School in northwest Connecticut, follows college admissions criteria closely. Two of her former graduates are now at Harvard and a couple of others have recently graduated from Cornell. 

She said universities have become less focused on calculus in recent years: Their decision to admissions tests from consideration means they are looking at students more holistically, placing less emphasis on any one class. 

But, Veatch said, many top-ranked universities urge students to take the most rigorous course available. For those at her high school, that means Advanced Placement calculus. The campus hasn鈥檛 offered AP Statistics for years. 

鈥淚n general, when I advise students, I say, 鈥榊ou need to max out on the curriculum,鈥欌�� she said. 鈥淏ecause that鈥檚 what I鈥檓 being told.鈥�

Maxing out, of course, means something different from one state to another as several are reassessing their mathematics offerings.

California has tried to broaden high school students鈥� opportunities by providing other academic pathways, not just those that lead to calculus. 

But there鈥檚 been a push and pull between , with the state recently backtracking on a key issue for college applicants: The faculty committee that sets admissions requirements for the U.C. system that data science could no longer be a substitute for Algebra II. The state Board of Education, which oversees K-12 and is looking at reframing math statewide, soon after removed its endorsement of data science as a substitute for that subject. 

, a crown jewel in higher education in that state, recommends four years of rigorous mathematics 鈥� including algebra, geometry and trigonometry.

鈥淲e also welcome additional mathematical preparation, including calculus and statistics,鈥� its website advises.

Calculus is not necessary for entry to the University of Wisconsin. But spokesman John Lucas said direct admittance to the engineering program is highly selective, 鈥渟o, it鈥檚 rare for a student to not have taken calculus.鈥�

Georgia Tech is a bit more explicit. Laura Simmons, an admissions counselor there, said in an , that students should take the most challenging courses available to them. If that means seeking out a dual enrollment math class at the local college, they should choose wisely.

“We’re never going to pretend that college algebra is the same as a calculus class,鈥� she said.
