Video Resources As a result of advancements in technology and faster internet becoming available today, it is now possible to stream videos on YouTube and Vimeo. Physical education teachers can take advantage of this and recommend workout videos to students, as well as other types of content which provide useful demonstrations for skill development. Whether they are dance or yoga videos, students may become so entranced with some YouTube channels that follow them, encouraging them to do even more than the teacher asks. No matter the level of the class, teachers will be able to find age-appropriate videos to share. Last, but most certainly not least, PE teachers can consider flipping their classes with the help of videos they make demonstrating technique, freeing up time for more application and review in class! 

How does it work? The magic happens on the surface of a special crystal called lithium niobate (LiNbO3), which boasts excellent optical properties. Beneath the surface of the LiNbO3, microscopic channels, or "waveguides," are created to confine light passing through. A metal electrode is then deposited onto each waveguide, which can produce surface acoustic waves.

Instead of a color wheel, any color combination is possible with their approach simply by altering the frequency of the signal sent to the "white waveguide pixel." In other words, Smalley said, "we can color the output of our display by 'coloring' the frequencies of the drive signal." "As a bonus, this interaction also rotates the polarization of the signal light so that we can use a polarizer to eliminate any noise in the system," he added.

Pavlo Viktor, a science teacher in Odesa, Ukraine, started posting his lectures on YouTube for absent students. He never expected the videos to gain millions of views beyond his classroom. For five years, he has been recording the videos for the students of the secondary and high school, and now he has more than 167,000 subscribers and more than 8 million of the views.

According to a research study, “IoT in Education Market” by MarketsandMarkets, the global market size is expected to “grow from $4.8 billion in 2018 to $11.3 billion by 2023.”

Personalized Learning One of the biggest hurdles with the typical education system is the lack of flexibility in the course work. The course is the same for each and every student. The human-to-human interaction in a classroom space is collective and does not take into account the individual pace and needs of the student. Building on the idea of Big Data collection, with IoT each student can be evaluated and monitored on an individual basis. Weaker students may be granted a modified course work that caters to them individually to bring them up to speed. On top of that, the aggregate data can guide the instructors to modify the coursework on the go depending on the collective class needs.

More Human-to-Machine Interaction

The global eLearning market was worth an impressive $107 billion in 2015 [1]. By 2025, however, Research and Markets believe that it will reach a staggering total market value of $325 billion [1]. The reasons for this explosion in value come on the back of several main drivers: the need to educate vast numbers of people at low cost, the falling price of learning solutions, the needs of the modern workforce to engage in life-long learning, and the fact that learning through an internet portal is often more convenient than going to school. The majority of the growth in the eLearning market will come from demand in developing countries.
