Students: 25378, Price: Free

This course introduces the fundamental concepts of electric charge, electric force, and electric fields, using hand-drawn animations.  This is excellent for students who are taking a physics class but need extra help understanding the material, whether it's because your teacher is hard to understand, you miss some lectures, or you'd simply like a fresh perspective.

Master the Core Concepts of Electricity & Magnetism in this Introductory Course

  • Learn the fundamental concepts, electric charge and electric field, that help the rest of the course go more smoothly.
  • Understand how charging by induction really works so you can guarantee you'll get those grades on your unit test.
  • Explain how the electric field is independent of the test charge.
  • Solve problems involving electric charges moving through electric fields.


Boost Your Grades in Your Electricity & Magnetism Physics Course

This course will boost your physics grades by clearly explaining the fundamental introductory concepts and giving insight into what sorts of difficulties professors like to introduce in exams.  Here, you will learn all about the first two chapters, on electric charge and electric fields, of a standard physics course on electricity and magnetism.  The course author uses his experience teaching college physics to highlight the key ideas and dangerous misconceptions while having some fun with hand-drawn animations and some goofy examples.

At the end of this course, you will have a solid understanding of electric charges and electric fields, and you will know what mistakes to avoid so you can get better grades on your next test or exam.

AP Environmental Science

A practical guide to Environmental Science

Created by Vedika Shenoy - Instructor

"]

Students: 10733, Price: Free

AP Environmental Science is a course that gives you a chance to "learn about the natural world," and to "study both human-made and natural environmental problems," as stated on College Board. Currently, however, it is clear that many students are not reaping the full benefits that this course has to offer. As shown by the most recent exam score distributions in 2016, a majority (54.4%) of the students taking the exam did not pass. Additionally, the mean score sat at a low 2.55. 

So, why is this? 

As a student who actually self studied this course last year (and got a 5 on the exam), I realized that prep material, while structured, was not actually conducive to helping the student make connections between concepts as was intended by College Board. 

There is a large volume of information that you are expected to know for this exam - everything from laws, to case studies, to chemical reactions. Now, don't let this scare you - the material is incredibly interesting, and if presented in the correct manner, is possible to internalize fully. The problem is, in most books, this is not the case. Information is presented in a somewhat disjointed manner - water concepts are discussed in an early chapter, but water pollution itself is not actually discussed until some 200 pages later. 

With this course, I hope to accomplish a few things. 

Present information in a manner most conducive to learning. 

As I just mentioned, the information presented in most prep books makes it difficult to draw connections between various concepts. With this course, I have rearranged a few concepts slightly in a way that I, as a student, felt was best for my learning. 

Review and clarify information tested on the exam. 

Within this course, I have created short and to-the-point videos that allow students to review and learn the basic concepts that will be tested on the AP exam. i have created short review sheets for each section, and have also recommended exercises from a few other books that I felt prepared me well for the exam. 

Focus on the free response section. 

I said before that the scores distributions for the AP Environmental Science exam were terribly low. This is most likely due to the fact that many students perform badly on the free response section, which accounts for 40% of your total score. In my videos, I have placed an emphasis on the free response questions, as these rely most heavily on making connections and using your problem solving skills. 

Give you a basic introduction to environmental science and various overlapping fields. 

Not only do I want to prepare you for the AP Exam, but I also want you to leave with a basic understanding of environmental science. The curriculum for this course doesn't only focus on science - it also touches upon laws, politics, and businesses, among other things.

The Vocabulary of Science: First Steps to Science Literacy

Learn to think more critically about science by mastering the language we use to talk about science

Created by Kevin deLaplante - PhD, Philosopher, Founder of the Critical Thinker Academy

"]

Students: 7443, Price: Free

WHAT IS THIS COURSE ABOUT?

Is evolution a theory, a fact, or both? This question has been debated by critics and defenders of evolution for many years.

Some claim that evolution is a theory, not a fact. Others claim that evolution is a fact, not a theory. And still others say that evolution is both a theory and a fact.

What exactly is going on here?

One reason why the debate persists is that people disagree not only on the strength of the evidence for evolution, but also on the meanings of the key terms, “theory” and “fact”.

This course is designed to help you understand and think critically about debates like these, debates about the nature of science that turn on the meanings of scientific terms like “theory”, “fact”, “law”, “hypothesis” and “model”.

ABOUT YOUR INSTRUCTOR

I have 20 years of experience teaching the history and philosophy of science at the university level, but now I work as independent online educator. I have given lectures on the topic of science literacy to national and international audiences.

I have over 30,000 students on Udemy, where I also offer courses on critical thinking and argumentative essay writing.

WHO IS THIS COURSE FOR, AND WHAT WILL YOU LEARN?

This course is for anyone interested in learning more about how a philosopher of science thinks about science and scientific reasoning.

It will be of special interest to science students, science educators of all kinds, and people interested in debates about the nature of science.

In this course you’ll learn the various meanings of the key terms, “theory”, “fact”, “law”, “hypothesis” and “model”, as they're used both within and outside science.

You'll learn the most common confusions made by people who write about science.

And you'll have an opportunity to test your understanding through quizzes and a video critique assignment.

Created by Scott Redmond - College Physics Tutor and Former Professor

"]

Students: 4489, Price: Free

This course
teaches introductory physics students how to
calculate torque and how to set up free body diagrams
and solve problems involving torque. Torque is one of the
trickiest concepts in introductory physics, and it is quite common
for students to stumble with it at first.

This
course is designed to teach you the fundamentals as quickly as
possible. Using short-and-sweet videos, this course
breaks torque skills into bite-sized chunks and gives lots of
practice with detailed examples and rapid-fire calculations in
which you pause the video to try the problem and then resume to see
how you did. You can save time by using this interactivity to
master torque in one shot, and you can also pick and choose
individual topics to review specific skills or even speed up or slow
down each video to help you understand it better.

The
vast majority of this course is video. There is also a PDF
worksheet that you may optionally print out to help you understand
some hands-on concepts.

Before
taking this course, students should understand vectors, especially
vector components. It can help if students already know
how to use geometry and trigonometry to find angles between
lines, although this is demonstrated in many examples.

The
goal of this course is to give you the benefits of a private
tutor at a fraction of the cost. This
course is perfect for students who need to catch up with their class
on their own time, who don't learn well by reading their
textbook, or who want to learn tricks and techniques to master torque
faster and easier than studying on their own.

This is a training MOOC for chemical hygiene. The primary goal is to provide domain knowledge to the audience. These domain knowledge includes how to read safety data sheet, how to recognize specific labels et al. The second goal is to provide some kind of skills or correct responses in different scenarios. These skills will be like how to properly label containers with chemicals, how to properly deal with a leak in laboratory and what is the suitable reaction to a fire in laboratory.
