Why wouldn't math, science and English be on-line? Some science would need labs. But a lot of these topics could be online. I have a niece and nephew who did their high school completely online. They concentrated heavily in the STEM area. Our school system allows this was a home-school hybrid. The kids who chose this track out perform the traditional high school.
As a firm believer of social interaction and an educator, I usually shy away from on-line classes.
Course that was before a female student at my school was bullied, cyber-bullied and hung herself. She was a "pin-up" girl, sweet, kind to anyone. She was told how fat, ugly, wh0rish she was. "Some guy" led her on, and dumped her when everything came out about her "alleged" activities. The school tried to sweep it under the rug, of course.
When I first started my PhD... I studied several types, the Ted Bundys, Richard Chase, Henry Lee Lucas, etc. Then we hit teen suicide. This was just coming to the forefront. I read what happened to Phoebe Prince almost two years earlier. It took me five times to read the whole backstory. Let's say the paper I was reading was wet.
When I grew up in the 1970s and 1980s we had bullies but that was a couple times a day, at school. You went home. Worst case... they get your # and hang up on you. Soon enough the parents call the phone company and that's easily solved. But it's not that way anymore. They bully kids at school AND when they are not at school, social media. It is now 24/7 bullying. When I grew up, maybe 30-45 minutes.
So today... I am more and more leaning towards OLC. Many kids learn better in that environment. Much less bullying, group stalking. How many people do you really stay in contact with after HS? Maybe a handful... But I cherish my HS years more and more as time passes. Things that happened then, just didn't make sense. As time passed, they did.
Ele.... TN has one of the worst educational systems in the country. 51st in reading. What's that mean.... if Puerto Rico was a state, we'd be 52nd. TN is about 15-20 years behind some states. In the end.... the state wants virtual classrooms where one certified teacher can teach 200 students at once and have 7-8 para-pros. Reason..... lower cost. Certified teachers are slowly being phased out.
If the OLC are in line with state standards and are in sync with colleges they wish to attend, why not? TN recently adopted a EOCT for advanced math, science, english, history, and a few others where you can take an end of year test and receive college credits. Advanced students graduate high school and that Fall, they're already through with most of their junior year of undergrad. TN hasn't had this long. Others states had this 25 years ago... What's that say about TN...
