20 or 30 years ago, computers were huge, and very heavy and this made them impossible to be
carried around. Also the computers were really slow and had very little memory.
Now, the laptops have a lot of memory and are really small and light, which makes them very
easy to be carried around.
In 2020, computers will be holographic, everything will be done with physical intervention of the
user (more than just typing or moving a mouse)
This computers will be used by both students and teachers and it will provide an easier to use
computer for small children, and it will also provide a different teaching technique, which will be
more appealing for children and will also facilitate the teachers work (it will be easier to use the
holographic computer than doing all the work in paper and by hand) e.g.. Surface, provides
better organization and much more tools like zooming.
One of the main challenges will be the cost as it will require new technologies (like sensors for
example, and this might make the computers more expensive and sometimes unaffordable)
In the past, overhead projectors were used, this used acetate paper and projected what was on
the paper. The problem was that it needed a very dark environment and it was really big and
heavy and could only project images.
Nowadays, projectors are used which provide a very clear image and can also project videos.
The size of the projectors vary a lot but some can be really small and light, permitting the
transportation of it and it can be connected to a vast number of hardware.
In 2020, holographic scanners will be used, which will be able to project 3D images and videos.
This will be used by both children and teachers but mostly by teachers. Teachers would use
this holographic projectors to provide a new teaching technique to keep the children interested
on what is going on.
A challenge is that it will require probably lot of training. Also the price of the projectors might
be really high due to the technologies it uses.
Schools can be receiving classes from a teacher from Harvard via video conferencing calls
Before: using chalk boards – writing on boards by hand – teachers hand to attend school – of
they didn’t then students had no way of having class unless other teachers covered for them or
the task had to be written on the chalk board
Now: using white boards and smart boards – teachers can project computer documents, videos
and other dynamics for students to learn more creatively – teachers could leave set class
work/homework projected when they were not there and students could send their work by
After: students will be able to receive lessons by others via conference calls
Teachers can use them to have more dynamics during class
Students can benefit from this by being able to receive more advanced classes for better
preparations for universities
Stakeholders: students and teachers - Students won’t have to miss classes if a teacher is away
because they can receive it via video conferencing calls
Challenges: can depend on internet access so when internet connections are slow this can be a
problem and can prevent video conferencing from occurring
Instead of having cleaners at school, they can be replaced by robots that are programmed to
clean school floors, windows, and classrooms, pick up trash etc.
This will affect cleaners because they will be replaced therefore no longer have their jobs
Before: cleaning had to be made by people, they didn’t have many resources to clean with –
just mops, brooms, buckets etc.
Now: cleaners have better tools – machines to clean floors, vacuum cleaners etc.
After: cleaners can be replaced by machines/robots that do the job by themselves
Stakeholders: cleaners, school, teachers, students
Can benefit the school in terms of less costs – also robots do not need vacations, they can be
cleaning at all times, no need to pay them simply pay for repairs or maintenance
Challenges: students can not take care of robots, kick them etc, students can become lazy and
not clean after themselves just because they know robots will do their jobs for them
Before: little planners where used in school to annotate and write down the homework students
Present: more advance planners, even PDA’s are being used to annotate the homework student
Future: Only PDAs are used. Better organization, and will allow events to be modify without the
need of making a big mess around the place.
Students: will have a more efficient schooling environment. More ease to remember school homework that
may lead to better education and school grades.
Teachers: similar to students, more organize way to store and annotate work that have and had to be done
Cost of getting these PDA’s. The purchasing of all the PDAs for all the students of the school may mean a
huge money investment, because PDAs are really expensive.
Educating on how to use these PDAs. People have to learn how to use these PDAs, these might mean a
higher monetary investment, (because people have to be trained on how to use them). Also, some people
might even give up on learning therefore the school will have lost a lot of money
Before: no lockers or wooden lockers were used. Were easy to open or break to
get other peoples personal belongings
Present: Metal lockers are being used. Sometimes, rusty leading the locks to
break, and leave belonging unsecure.
Future: Safe deposit boxes can be used in the future. Belongings will be much
Students: more secure place to store their belongings
Cost of getting these safe deposit boxes. Purchasing the boxes will be a huge monetary
investment, therefore the school will have to spend more money on buying this boxes
Lock combination can be figured out by other students, thus the belongings wouldn’t be
