BISMARCK, N.D. - While school might be out for the summer, some teachers use this time to enhance their skills in the classroom.
Fifty instructors across the state are in Bismarck to learn about North Dakota's petroleum industry.
Monday kicked off the four-day seminar where they'll expand their knowledge on the oil process and even get to tour a drilling rig.
"Trying to figure out ways to bring in real like applications of mathematics, and that's what I'm hoping to get from this, some energy applications that are pertinent to our state," said Randy Holzkamm, West Fargo High School Math teacher.
The seminar has been hosted by the North Dakota Petroleum Council for more than 30 years.
