MATTAPOISETT — Old Rochester Regional School District students tested comfortably above the state average in 2024 MCAS exams in all subjects, but student learning in one field is shining brightest.

In science MCAS exams, fifth grade, eighth grade and high school students collectively exceeded the state average score by 17%, and district scores increased by 8% from 2023.

Eighth grade students surpassed the state average score by 19%.

A breakdown of MCAS results was presented at a school committee meeting on Thursday, Dec. 12.

Administrators say that OpenSciEd, a science curriculum used by the district, has been a successful learning tool.

Shari Fedorowicz, the assistant superintendent for teaching and learning, said the “inquiry-based” curriculum has been “working its way through the district.”

“OpenSciEd empowers educators to go beyond traditional science teaching methods by bringing together leading science researchers and educators to craft curriculum that is aligned to how students learn best,” reads OpenSciEd’s website.

Old Rochester Regional Junior High School Principal Silas Coellner said students showed strength in MCAS questions on topics they have learned about through OpenSciEd, and weaknesses lie “where we aren’t at yet.”

The curriculum covers two units per school year.

“We are not covering as much material, but what we are learning, we’re learning really well,” said Coellner. “It’s been great watching the kids apply those skills.”

Students at all four Tri-Town elementary schools have been taking science classes that are part of the curriculum.

“Its very clear when you go in the classroom, they are coming with common experience from elementary schools,” said Coellner.

He said he has heard from teachers saying “they are becoming little scientists.”

“[OpenSciEd] is developing, it’s growing and the kids' scores are showing it,” Coellner said.

High school Principal Mike Devoll said the curriculum has “really pushed” achievements in the subject field in the district.

“As teachers unpack new units each year, expect success to continue,” said Devoll.

On the 2024 science MCAS exam, 59% of district students met or exceeded expectations, which is up 8% from 2023.

“It’s pretty neat that we are defining what we want our kids to be learning and moving in a direct, consistent approach for all kids,” said Superintendent Mike Nelson. “I find it exciting and motivating.”
