Does the Sun always rise in the east and set in the west?

 The Earth is divided into the Southern Hemisphere and the Northern Hemisphere by the equator


About 23,50 above and below the equator are the Tropic of Cancer and the

Tropic of Capricorn respectively. The path followed by the Earth

around the Sun is called the ecliptic and a perpendicular line from the ecliptic

plane makes an angle of 23,50 to the earth’s axis of rotation.

This tilt is the primary source of the seasons on Earth.


The earth is rotating around its axis from west to east making the sunrise from

the east and set in the west. The question is, Does the sun always rise in the east

and set in the west?


Due to the Earth’s tilt, the sun crosses the celestial equator from north to south

around September 22nd or 23rd (23rd Sep 2023 @8H50 SAST)


From there the sun seems to move towards the south each day until on 
summer solstice (Dec 22 2023 @05H27 SAST) where it rises and sets 23,5
South of the East. From there the sun seems to move back toward the east and 
will cross the celestial equator on March 20th, 2024 at 05H06 towards the 
Northern Hemisphere to reach the Tropic of Cancer, our winter solstice 
(June 20 2024 at 10H50). From there it will be returning back south. 
To answer the question posed, the sun rises from the east and sets in the west 
only two days a year.

Title . : Reflection on Rethinking ContentCreation in
Virtual Environments
Date : 29 September 2019
Presenter: Dr Ramloll (Ramesh Origin), John Origin
and Ann Nowak(Ann van Rhien)
Event . : Virtual World MOOC 2019

Where . : Online




Description of the event
RezMela island has small application called apps, which can be
manipulated to create scenes by anyone without the building or
coding knowledge. 
                               Source: VWMOO19 Video
The presenter demonstrated how the apps can be made to upload,
create, save, and even share the scenes. After the demonstration,
the participants were given the opportunity to explore the apps.


Connection with the Presenter and/or Participants
There were two types of participants, those who were on land (SL)
and those who were not on land (Zoom and Facebook), there
where even those who can be in the three at the same time.
Due to some technicality, I was not able to connect directly with
the presenter but with other participants through zoom chat, and
our questions and the presenters answers were passed on
between different platforms through the event organiser.
Questions During the Event
During the presentation, I was asking myself of how I could make
the apps to be suitable to the environment of my learners. I believe
that for learning to be effective, the learning environment must not
be too different from what the learners are used to.
How the content relates to me as a learner and a teacher 
I was really impressed by the fact that to create the scenes, there is
no need for building and coding background. As a result, I can
modify of build scene that suits my personal situation. 
How I Felt During the Presentation
I am over the moon about this world and I feel I cannot wait to visit
the island.
The Challenge in The Implementation
I think the main challenge is for me to learn the basic manipulations
in virtual worlds. I am being encouraged by other participants to get
inland and learn by doing, learn from my mistakes. 
Step to be taken to resolve the challenge
I need to share what I learned with people around me and develop
a local network to assist each other. 
What I would like to do in the future as a result of
this event
I would like to learn the basic features of virtual worlds and to learn
from within.

What I would like to research as a result of the event
As I have mentioned earlier, I  need to improve my skills
in controlling the movements of the avatar and do some
research on survival skills in virtual worlds.

Title: Web Based Virtual Worlds Coming of Age
Date: 18 September 2019
Presenter: Dieter Heyne (Avatar: Edward Tarber)
Event: Virtual World MOOC 2019
Where: Online



The presenter explained how they started their web based
virtual world, CybaLounge, which can run in every major
browser.


The following features and benefits were discussed
  • General benefits
  • Benefits for educators
  • Basic features
  • Communication features
  • Security features and
  • Advanced features.

The presenter further explained that in future the
avatars will have finger movements and facial expressions.


I have not yet connected with the presenter but with other
participants on the chat box. We were provided with
addresses which I used to enter the virtual world and I was
so impressed. Some of the questions I had were
answered through FAQs .

As a Physical Science teacher, I had questions relating the
number and safety of learners for practical work , and the
cost of apparata. The major question of having practical
work was answered by the presenter when he talked about
the physics engine, where simulations behave as in real life.

My interest to learn to teach online was enhanced. I think
through virtual worlds learners will not feel isolated as I
thought before.

I am fascinated by the way virtual worlds are leading teaching
and learning were teachers will be elated to teach and learners
excited to learn.

The major challenge in countries like mine is the infrastructure.
The cost of data is still too high, more especially for low income
communities.

I believe that access of data is no more a want but a need just
like water. Data need to be freely available to all and teachers
to be retrained.

I am inspired to learn more about online teaching and learning
which includes the use of virtual worlds.

I would like to understand more about virtual world especially
web based virtual worlds.

Biker Librarians Hit the Road
Date:15 September 2019
Presenter: Dr Valerie Hill (Valibrarian in SL)
Event: Virtual World MOOC 2019
Where: Online




Biker Librarian Hit the Road is about metaliteracy while biking from
North Fall Rez up the hill to North Fall City.The bikers were given instructions
by Valibrarian before they left the starting points. Among the
instructions was that they should read signs along the roads and
they were warned not to be too fast as they may fall from the rails.


Viewers outside second life, were lead  Maggie Larimore as she
biked up the hill. The bikers passed through interesting places
like Secoya and then a place were they tunnelled below the ocean.


Finally the city was reached were discussions were continued,
and my main take home was that children in the future will
easily juggle between the real world and the virtual world while
appreciating both worlds.


Connection with the Presenter and/or Participants
I was active through the zoom chat with other participants. I also
enjoyed Valibrarian second life slide show.


Questions During the Event
While watching Maggie riding up the road, I was asking myself
if it was safe, more especially as she passes through the bridges. 


How the content relates to me as a learner and a teacher 
At some times, I was relating this to computer games, although I 
have not played the games, but I was thinking of falling over or
getting lost. 


How I Felt During the Presentation
Although I was watching from outside Second Life, I felt so scared
as if I was inside, The heights, bridges and the sand made me feel
very uncomfortable.  


The Challenge in The Implementation
It will take me some time before I can talk about the implementation.
I still need to overcome the uncomfortable experience I had in the
virtual world. My time will come.


Step to be taken to resolve the challenge
My fear for the unknown are gradually fading away as I read more
about the virtual worlds and I am being encouraged by other
participants to learn from the inside. Hopefully I will overcome
this challenge soon.


What I would like to do in the future as a result of this event
I will keep on reading about how to get information about virtual
worlds more especially the information relevant to K-12.


What I would like to research as a result of the event

I think understanding how the brain works will help a lot in
understanding the virtual worlds better.

Title: Virtual World Education Overview For Newcomers
Date: 2 September 2019
Presenter: Dr Nan Zingrone
Event: Virtual World MOOC 2019
Where: Online


Description of the event
Dr Zingrone dealt with the history of distance learning and the advice to
newcomers on how to get information and resources in Second Life.
Although she dealt with Second life, The advice could work in other
Virtual Worlds.

According to Dr Zingrone, the first advertisement was for teaching
shorthand on a penny postcard by Caleb Philipps in 1728. The distance
learning programs improved over the years until they were significantly
improved by the radio and television. The first Universities
telecommunication conference was in 1980.  

The first virtual World was from the University of California for
students of Virtual Campus Supercomputer Center (VCSC) students only.
Today there are a number of virtual worlds.

Dr Zingrone concluded by giving advice on how to find resources,
finding people and finding one’s looks.
Connection with the Presenter and/or Participants
I have not connected with the presenter or the participants but
I have visited the presenter and her husband website,
The Alvarado Zingrone Institute for Research and Education
and hope to revisit to read more about Second Life.
Questions During the Event
The question that came into my mind is “how the world could
be a better place if learning could be in the virtual world,
where all learners, irrespective of their background could l
earn together.
How the content relates to me as a learner and a teacher 
Personally as a science I see many possibilities like virtual laboratories,
which will make practicals save and cost effective.On the other hand,
I cannot see this happening in  third world countries as some still lacks
basic internet connections.   
How I Felt During the Presentation
The fact that people can meet each other, under the same
roof, though virtually made me feel good. I strongly feel that,
if the educational systems can go this route, then we will
be able to overcome inequality in education.
The Challenge in The Implementation
There’s still a lot to learn before I can implement or introduce
virtual world in my area. We still lack some infrastructure and
we still have to go a long way as teachers. 
Step to be taken to resolve the challenge
For now, I need to inform all my contacts about the importance of
virtual learning and develop local learning network to assist each other.

What I would like to do in the future as a result of this event

I would like to learn the basic skills for virtual world, so that I should
not have any doubts to join other participants in the next MOOC.
What I would like to research as a result of the event
As I have mentioned earlier, I  need to improve my skills in
controlling the movements of the avatar and do some research
on survival skills in virtual worlds.

Reading on Paper or Digital Screen

Date: 30 May 2016
Presenter: Dr Nellie Deutsch
Course: MOODLE MOOC 8
Where: Online (WizIQ)

Description of the event
Reading on paper or digital screen webinar was presented by Dr Nellie Deutsch online on WizIQ on 30 May 2016.

Reading according to Dr Deutsch is anything based on text. We read a multiple screen or paper.

We were not born to read and our brains have developed due to reading and writing. We need to read in order to develop and share information. The more we read the more our brains develops.

There is no difference in our brains as we read from screen or paper and the pleasure of reading from paper or screen depends on individuals.

Dr Deutsch cited Goleman who said “We learn best with focused attention”.

The destruction that may challenge our reading can be either sensory or personal.

Connection with the Presenter and/or Participants
I was active on the chatboard and moreover I follow Dr Deutsch on twitter and facebook.

Questions During the Event
Where could we have been if we did not learn to read and write?

How I Felt During the Presentation
I felt good since reading takes a major part of my life.

Thoughts that went through my mind
The Thoughts that went through my mind is that through writing and reading we understand ourselves and the universe better.

The Challenge in The Implementation
We need to learn to share and collaborate effectively. The challenge we face is to be able to differentiate what is authentic from what we read because anybody can write and publish publicly.

What I would like to do in the future
Realizing how one learn effectively by writing reviews of what one has learned, I would like to gain confidence in publishing what I write so as to instil reading to all around me.

Questions I would like to research
I would like to know the effective way of reading without distractions and how to read speedily with understanding.
