Navigator Academy, which launched in November 2009, has been touted as the first step towards the next generation of navigators.
It has a focus on helping people understand their environment, and is one of the first search engines to have a navigator who is fully trained and experienced in the subject.
The class has been available for people with disabilities since the beginning.
Google says it has seen a 50 per cent drop in accessibility problems over the last three years, with more than 70,000 people taking part in its first year.
But the course is also available to anyone, and has been seen as an opportunity for a new generation of engineers to learn how to solve real-world problems.
It aims to help people find jobs, and can teach people how to identify and avoid hazards on the road, for example.
But it’s also been criticised by some who have complained about its “in-depth” approach to the subject, and claims of its emphasis on “narrative building”.
A recent survey by the US-based non-profit advocacy group, the Association for the Advancement of Colored People, found that a large majority of people in the US would be more likely to consider the course if it included non-white, deaf and hard-of-hearing students.
It said that in many areas, the curriculum was too “deep”, and did not focus on the practical challenges of navigation.
It also found that the course’s focus on story telling had created an expectation of a professional education, which the association said was not supported by research.
The new courses offer students the opportunity to “work on their own solutions”, but they are not given any support or guidance from a professional navigator.
A number of courses that focus on different topics such as “real-world engineering” or “how to build a home” are also available.
Google has said that the courses are designed for people who are “enthusiastic about technology”, and are not aimed at “narrow-minded people” who are used to thinking about technology in isolation.
It wants people to understand that “navigation is all about what we do, how we do it, and how to do it well”.
And it has stressed that the focus is on creating solutions for real-life problems, rather than a “visual” or technical curriculum.
But some say the course has been oversold by Google, and it could make the search giant’s search rankings less competitive.
The search giant has been trying to expand its range of navigator courses by offering courses in areas like engineering, business, design and technology.
But in the past few years, it has also expanded the range of classes, including some in languages, including Spanish and Portuguese.
