What is Online classes: Definition and 71 Discussions
Educational technology (commonly abbreviated as EduTech, or EdTech) is the combined use of computer hardware, software, and educational theory and practice to facilitate learning. When referred to with its abbreviation, EdTech, it is often referring to the industry of companies that create educational technology.In addition to practical educational experience, educational technology is based on theoretical knowledge from various disciplines such as communication, education, psychology, sociology, artificial intelligence, and computer science. It encompasses several domains including learning theory, computer-based training, online learning, and m-learning, where mobile technologies are used.
I am currently in a college. And the college that I am currently at doesn't offer the class online. Can I go to a different college to take the classes online, and still be at the same college I'm at? I need the class online, it makes my school life and work life function more smoothly.
I am tutoring a student on 7th grade math via zoom. I am using graphics tablet myself to write down my exposition.
My student solves problems on his (paper) notebook and tells me what he wrote/how he thought it out and I re-write it on the screen and make eventual corrections.

May be a dumb question, but I know very little about online classes. My main question is, and I assume it does vary depending on a number of factors, but in general, is it possible to complete online classes while working a full time job with sometimes up to 80 hours a week or more. For...
Hi, I was wondering if anyone knew of an online calc-based physics 2 course with a lab? I know it's a lot of criteria to match and I've had a pretty hard time searching, but I thought I'd ask in case someone else has taken or is aware of something! I need to take it this summer in order to be on...

I hate to admit this, but at the same time its true.
I have worked as a math tutor for 6 years. I have poured everything I've ever had into studying math and physics for the last 6 years as well, but one thing I just dislike is when I have to learn a new subject for the first time while taking...

I am only able to take nine hrs of traditional classroom setting a semester how much more difficult are online classes in this field as opposed to traditional
My school offers online courses and I'm considering taking one for Precalculus (to brush up on my skills before taking Calc.).

Hi... So I've been self-teaching Calculus III and I'm currently having a hard time coping with the idea of triple integration. You know how the integrand is f(x,y,z)? isn't that the equation to represent a 4D sketch? because technically, f(x,y,z) is ANOTHER VARIABLE and therefore giving us a 4...

I saw a video of Jack on Upworthy this morning. Interesting kid.
I read several articles about him. Someone at Forbes said they didn't include him in their "30 under 30" list, because he'd never published in a peer reviewed journal, nor were his numerical claims correct.
I thought that...
Sorry to deviate from the very obvious instructions in red. The problem is I need help with 4 questions and they each have figures so its much easier to upload.

My college offers both online and offline math classes. I'm to the point now, where the math classes offered online are fewer, I need I believe up to calculus. I like the setup of online because I work like most people, and it gives me a week to complete homework and tests, rather than 2 days...
So this is a review problem in our book I came across and i really want to understand it but I am just not having any luck, I did some research and found a guide on solving it but that's not really helping either. We didn't talk about unity elements in class and there aren't any examples in our...
Whenever I'm on math class I've noticed that often professors, and in my online class the videos and examples all seem to be the most complicated way to finding the answer. For example if solving for an equation by elimination they'll go for eliminating y, even though you could just as easily...
Hello, I have two questions today
