Although bear-like, koalas are not bears. They are mammals, so feed their young milk and are marsupials, which means that their babies are born immature and they develop further in the safety of a pouch. They are tree-dwelling, herbivorous marsupials, which average about 9kg in weight and live on gum leaves. Their fur is thick and usually ash grey with a tinge of brown in places. Koalas in the southern parts of Australia are considerably larger and have thicker fur than those in the north. This is thought to be an adaptation to keep them warm in the colder southern winters.

Younger breeding females usually give birth to one joey each year, depending on a range of factors. The joey stays in its mother’s pouch for about 6 or 7 months, drinking only milk. After venturing out of the pouch, the joey rides on its mother’s abdomen or back, although it continues to return to her pouch for milk until it is too big to fit inside. The joey leaves its mother’s home range between 1 and 3 years old, depending on when the mother has her next joey.

Koalas are mostly nocturnal. They sleep for part of the night and also sometimes move about in the daytime. They often sleep for up to 18-20 hours each day. There is a myth that koalas sleep a lot because they ‘get drunk’ on gum leaves. However, most of their time is spent sleeping because it requires a lot of energy to digest their toxic, fibrous, low-nutrition diet and sleeping is the best way to conserve energy.

The koala gets its name from an ancient Aboriginal word meaning “no drink” because it receives over 90% of its hydration from the eucalyptus leaves (also known as gum leaves) it eats, and only drinks when ill or times when there is not enough moisture in the leaves i.e. during droughts, etc.

Artificial intelligence (AI) and related technologies are increasingly prevalent in business and society; besides, they have been applied to education. These technologies have the potential to transform many aspects of the teaching - learning process.

Basic activities in education like grading can be automated with the help of AI. At educational institutes, marking a large number of tests and assignments is tedious work. Teachers often find that grading takes up a considerable amount of time which can be used to interact with students and prepare for class. AI, at present, may not be able to actually replace human grading; however, it's getting pretty close. Nearly all kinds of multiple choice and fill-in-the blank testing can now be performed by Al-driven machines, and automated grading of student writing may not be far behind. Essay-grading softwares are still in their infancy, yet they will be fully developed over the coming years, allowing teachers to focus more on classroom activities and professional development.

Learners can also get additional support from AI. For instance, tutoring programs based on artificial intelligence already exist to help students with basic courses of mathematics, writing, foreign language, etc. With the rapid pace of technological advancement in recent years, sophisticated tutoring systems which can help students learn high order thinking and stimulate their creativity will not be a pipe dream. Moreover, Al programs can give learners useful feedback and assistance. Some schools, especially those with online courses, are using AI systems to monitor students' progress. These systems not only offer students advice on individual courses but also help students choose majors in accordance with areas where they succeed or struggle.

For better or worse, AI systems have taken place in certain types of classroom activities. In the next decades, their influences will extend significantly, which offers both teacher and students a much wider range of services.
