Online resources for first and second year STEM courses – the varsity


If you feel lost in the first few weeks of class, you are not alone.

The transitions from high school to grade one, and grade one to grade two are very sudden. It’s natural to feel unprepared for class schedules, and even a reasonable schedule doesn’t matter if your teacher confuses you.

So, for all first and sophomore students, we’ve prepared a list of some of the most useful online resources for STEM courses. You might even find that staying home and watching these videos is a better use of your time than going to class.

General: Crash course

The crash course is a training Youtube channel and the brainchild of TikTok sensation Hank Green and his brother, writer John Green. High school and early college students have been using the crash course for years to replace unprepared lecturers.

Each crash course focuses on a different topic and has a different presenter, aside from the occasional series featured by the Green Brothers. The completed series covered all areas of the STEM spectrum, including anatomy and physiology, chemistry, computer science, statistics, and zoology, to name a few.

In addition, Crash Course is partnering with Arizona State University to create a series called “Study Hall”. These videos focus on more specific topics than those explained in Crash Course, so they can often be a useful addition. For example, the Chemistry Tutorial in the Crash Course on Acid-Base Reactions pairs well with the Study Hall tutorial on Balancing Chemical Reactions.

General: Khan Academy

It is impossible to compile a list of STEM resources online without mentioning Khan Academy.

The nonprofit has been producing video tutorials for years, all using the same standard “Etch a Sketch” software. Their subjects tend heavily towards the high school level, so if you need a refresher on precomputing or trigonometry, they can be very useful – although it is difficult to use them for more advanced math lessons in the years. higher. The tutorials on Calculus, Linear Algebra, and Differential Equations will cover a lot of first and second grade material, but after that, you’re on your own.

Another drawback is their style of presentation. Khan Academy’s simple diagrams are no more fancy than a chalkboard, which means the difficulty of drawing insightful pictures in chalk carries over to their videos. The emphasis is on quantity, not quality.

Mathematics: 3Bleu1Brown

3Blue1Brown is everything Khan Academy is not. This is a series of animated and vivid videos that vividly illustrate math concepts, including those that are quite advanced. Grant Sanderson, creator of the YouTube channel, stresses the importance of understanding the concepts, not just applying them.

The Linear Algebra Series is a particularly strong example of Sanderson’s philosophy. It is a great addition to any first year linear algebra course, covering gaps where textbook explanations can often be very abstract. 3Blue1Brown’s videos show why a concept is useful, not just how to use it.

Physics: the digitized Feynman lectures

Richard Feynman’s lectures have long been famous among physics and engineering students for their clarity, insight, and sense of humor. When the Nobel Laureate’s lectures were synthesized into a three-volume textbook series, they became instant must-haves for first- and second-year undergraduates.

But you don’t need to buy them in bookstores. The California Institute of Technology made the entire series available in line, free of charge, as well as additional material and practical problems.

The lectures cover a wide range of topics with a depth that will transport you comfortably to second year physics classes. They are also accompanied by useful illustrations.

Coding in Python: Neural Nine

There are many online resources to learn coding, but the YouTube channel Neural nine stands out for its quantity and diversity of videos. The channel mainly focuses on Python. There are tutorials for people who are completely new to the language, but the videos are best suited for programmers with a bit of experience under their belt.

They dig deeper into specific Python tools and libraries and show how to create original projects, like a simple web browser or Twitter bot. Plus, projects are filmed in real time, so you can follow along without stopping to catch up.

There are many other resources. Ask around, you might find that the best resources are right next to you in the classroom.
