In an earlier post I designed a Sage Interact to generate data for continuous distributions. This week I've added a Sage Interact to generate data for discrete distributions. A screenshot of the Interact is shown above. To use the Sage Interact, copy the code posted on the Python/Sage page and paste it into any Sage Cell Server. Press "Evaluate" to start the interact. Pick the distribution you want to generate data for, adjust the parameters and the Interact will create your data as well as calculate standard statistics for the data. This is a quick way to generate examples for quizzes, tests, and lessons.
Here are some stories that caught my eye in the last week:
- the74million.org has a surprising piece on "Connecticut’s Shame: In One of America’s Richest Counties, a High School Has Been Failing for 50 Years". The school is so bad there isn't really any way to get worse "Even to the jaded, Bassick’s achievement statistics are disturbing. Last year, only 15 percent of students tested proficient in language arts on the new Common Core-aligned state tests. The percentage of students who met that benchmark in math? Zero." Good thing they have certified teachers getting the most out of them.
- Segregation--it wasn't that long ago. Actually, it's still going on. RT reports, "A northwest Mississippi school district has been ordered by a federal district court to "consolidate its secondary schools" that have long been separated along racial lines some six decades after the US Supreme Court ordered school desegregation.....“This decision serves as a reminder to districts that delaying desegregation obligations is both unacceptable and unconstitutional,” said Principal Deputy Assistant Attorney General Vanita Gupta, head of the DOJ's Civil Rights Division. " In what way was the 50 year delay shown to be unacceptable?
- Sputnik news notes that "A former elementary school paraprofessional in the Atlanta area must report to jail by 6:00 on Friday evening after being charged with reckless endangerment for hanging a five-year-old student by his belt from a classroom blackboard."
- Reason.com closes the chapter on a teacher who used the N-word in class. "Andrea Quenette, the University of Kansas communications professor subjected to protests and a formal investigation after offending her liberal students, was cleared of wrongdoing. But she is still ultimately out of a job."
- EAGnews with a horrific tale of
studentanimal behavior that was impossible to imagine decades ago. "South Fort Myers High School officials believe as many as 25 boys had “inappropriate activity” with a 15-year-old female student inside of a bathroom on campus Tuesday. Students told NBC 2 the incident occurred in a girl’s bathroom after classes ended and involved the school’s football team." The NBC 2 link has a video and there's another link here with a little more depth, "While she would not pinpoint why the different students were on campus after hours, she said South Fort Myers students involved in extracurricular activities — athletics or otherwise — participate in a study hall from 1:47 to 2:30 p.m. This is roughly the time frame for when the bathroom activities took place, Chandler said." So about 45 minutes in which we have dozens of students unaccounted for and no adult apparently around the area to see or hear what was happening.
- The Greeley Tribune on the decline of teachers in Colorado. "Since 2010, UNC has watched enrollment in its teacher preparation programs plummet from a high of nearly 4,000 in 2011 to just 2,900 last year. The state is expected to graduate only 2,000 next year, and it needs twice that amount, education officials say...There are states that are worse off than Colorado (Oklahoma, California). There are states that are doing better (Connecticut). But every state has seen its list of needs increase as the number of people pursuing teaching as a career has decreased." The school system is run by many people who aren't up to the challenge but there is little consequence for mismanagement and poor quality. Take the Connecticut situation above: what will be the consequence for poor performance? Will the school close for having 0% proficiency in math? How did the school get to a 0% proficiency rating with "professionals" running the school? Do teachers still get pay increases (above the rate of industry) for such an awful showing? Money will keep coming in from taxes, and the system will continue on. When there's no consequence for failure, expect more of it.
