In the Star Tribune's article, "Disabled students face dangerous discipline in Minnesota," the author examined state reports of complaints filed by students or their parents regarding physical discipline that teachers or school staff used on a special education student.
The author found several anecdotal cases that he used in his story to show the extreme type of punishment that is used in some cases. He also used the data to find interview sources, such as the mother of a son who a school staff person harshly disciplined.
People filed nearly 22,000 complaints last year, so the author probably had some type of data analysis program or perhaps the state already filed some type of report that the author had access to. He probably spent a fair amount of time going through the records himself to find the anecdotal cases.
The story included an infographic that included a diagram explaining different holds school staff use to restrain a student. The graphic also included a map that displayed which states banned certain types of holds and forms of discipline.
The article also featured video interview links and related articles in the side column of the website.
