TASK 2 TABLE

Projection	Robinson	Mercator	Azimuthal
Include a picture of it
Purpose	Show the globe on a flat image.	Used for marine navigation because all straight lines on the map are lines of constant azimuth	Equidistant projection is a map that is perfect for identifying antipodes. Because the border indicates the farthest you can get from point of tangency, in this case the South Pole.
Distortion types?	Meridians curve gently in the top and the bottom and poles stretch, Making the points turn into vertical as lines.	First, as I noted earlier, the developed countries are represented with a proportionally larger than they have, and this is done intentionally (or at least has no intention correct) to ningunear poor countries. Second, and this is something that costs me to believe it was originally said by Peters, the Mercator map gives more weight to the northern hemisphere to the south, placing the line of Ecuador not in the middle of the map, but a little below so that the northern hemisphere occupies 2/3 of the surface of the map, and south 1/3.	This projection distorts the relative areas, the size, the distance, the shapes and the angles.
Distortion – Areas that are more distorted?	So the areas more distorted are near of north and south poles.	A few major misconceptions based on this map: - Alaska is nearly as large as the continental U.S. - Greenland is roughly the same size as Africa. - Europe (excluding Russia) is only a bit larger than South America. - Antarctica dwarfs all the continents. In reality: - Alaska can fit inside the continental U.S. about three times. - Greenland can fit inside Africa about 14 times. - South America nearly doubles Europe's land mass. - Antarctica looks like the second-smallest continent.	Well, it depends on the type of azimuthal projection that you decide to use. Because the projection can come from the centre of the Earth, from the middle or from the top, and also from outside it. For example as we said before if we choose a map that it’s centre is the North Pole, the area which will be more distorted is going to be the South Pole.
There is more than one version?	NO	NO	1. Orthographic projection: an inside of this you have also polar projection, equatorial projection and oblique projection. 2. Stereographic projection 3. Gnomonic projection 4. Lambert azimuthal projection 5. Azimuthal equidistant projection
Problems?	Greatly deformed along meridians and farther north than it should appears.	The Mercator projection drastically distorts the size and shape of objects approaching the poles. This may be the reason people have no idea how big some places really are.	There aren’t any map projections that preserve the three parameters, distance, size and shape, it is impossible not to deform the Earth with this type of projection. However, thanks to the mathematics we can make some changes that allow us to maintain any of the parameters.
Socio-cultural implications of using it as a learning resource?	The map is distorted and doesn´t correspond to reality, but its distortion is necessary to adapt the geographic reality to a cartographic projection, and this kind of projection is easy to be explained on pupils and also our space logic can also appreciate the distortion and easily know the reality.	The map is more used to represent the globe especially by teachers and books, then all children imagine the countries as it type of projection shows the countries.	An azimuthal projection is therefore particularly suitable for small 'circular' features on the surface of the earth.

The stars of this week have done a good job! To present our work they have created a great PowerPoint and they have worked really hard. Due to they are not living in the same area, they have used skype to comunicate to each other and get a better presentation.

THE JOURNALIST

He uploded all the posts and cared about the twitter account. He managed to organize all the information in a really good way to the clear understanding of this task. As usual, we coment in one of the blogs of our teammate, take a look!

THE MEDIATOR

He also made a really good job organizing the work and giving us different tasks. He was always looking after us, making sure we all did the work on time and well.

ANALYST REFLECTION.

First, I would like to say that I do not think we have worked harder this week, but It is true that we have organised better our group. It is probably due to the fact that last week was the first task and we did not have totally clear what we had to do in our role, but we hope we will improve in that aspect as we work more and more. In that sense, we made various posters when we had to do only one, if we had concentrated to work as a team and had done one poster perfect It would have been better. Nevertheless, this week we have worked on this matter and the sensations we have about the results are much better, we had just one good presentation in the relation to the content, with the only problem that the letters were a bit dark, but our work is also available in the blog If anyone is interested. In addition I consider that one of the most tough things to do is taking decitions, it is difficult that 9 people agree in every aspect of the task, you may think you have a great idea while the others think it is not. In particular, we have discussed if we should do crafts, a poster to show the differences between the countries through the different maps, ones agreed and others thought it was better to show it in the presentation. Finally, we managed to reach an agreement and decided to do it. It is normal to have this kind of situations, in fact, it is vital telling if anyone is not happy with something because as a group decitions are made all toguether.

On the other hand, going straight to the activity of this week, I think the best part of this week has been discovering that we had a mistaken vision about how are countries, their location, and differences between them, and how this differences are conected to power and the imperialism conception, because untill now we only knew Marcator's map, which is in fact the most imprecise one, and I wonder why nobody tought us that at school. Investigating about that has been very interesting and concerning ourselves about how media can distort reality, seeing it through the different examples of our classmates and ours has made us reflect that we should be aware about what we see and being critic with information on the media. That is why is very important what we teach to children, because education is not neutral and we should try to let children interpret the world themselves. Also, we have discovered what is exactly a treasure hunt, because we associated it the typical game of the pirate and clues to find a treasure, but as we looked up for further information we realised it is actually a resource for the teacher to make the students investigate by using the internet. Its use is wispread, increasingly among little children, so it is crucial to teach them to use it in the right way.

The worst moment has probably been on the moment of the presentation because we did not expected that the letters could not be seen. For next time, we will try to think and work in a more analitic way in order to prevent unexpected situations.

In conclusion, for the following weeks we should try to maintain a good organization, and work as a united team because we are not used to work with such a big group, though I think we are on the way to reach it. Finally, I would like to remark that the contents that we have learnt are very useful for our degree and work as teachers, because they are interesting resources that we can use in a classroom.

I would like to finish with this phrase I have ridden and cheer my team mates because it is not just important to have good marks from the beggining, we have to learn from mistakes, grow and improve as a team “Effort is the mother of all the achievements”

THE CURATOR WORK.

This is the mindmap (Spider type) that shows the resourse we have use to complete the second tas about cartographic proyections. After the image there is a list of importat links we've used.

1.TREASURE HUNT

A treasure hunt is one of the most popular and simple activities used by teacher involving the internet. It consist of a paper or a web page with a series of questions and also a list of webpages in wich students look for answers. Finally, we should include the "Great question", wich answer does not appear directly in the web pages, and should assess what students have learned during the process of searching. thet are useful strategies to adquire information about an specific subject, and also to practice abilities related to technology and internet.

Here is an example of a treasure hunt about the rainforest in our planet. It is for students of the third cycle of primary education. In this case the teacher wants the student to acquire knowledge about rainforest, we guess It could be for the subject of natural sciences. We have chosen this example because it has a good presentation and it is well organised. First, it explains the task that the students should do, which is answering the questions below by searching information on the different links. Then they have to answer the final questions by making a reflection about what they have learned about rainforest. Finally, they have an extra task which is about drawing their favourite tropical animal including a message about the important of rainforest. We think this final task is for aware students in a funny way.

2.MAP PROJECTION

A map projection is a mathematically described technique of how to represent the Earth’s curved surface on a flat map. To represent parts of the surface of the Earth on a flat paper map or on a computer screen. It has to be represented using a grid of lines of latitude and longitude. In the entire world there are differents ways of projecting maps...

3. ROBINSON PROJECTION

The Robinson projection is a map projection of a world map which shows the entire world at once. He didn't use mathematical formulas for his projection, but tabular coordinates to make the world look good. The map divides lines of latitude and longitude throughout the projection. All lines appear curves, except for the straight line lenght in the middle of the map that passes through the central meridian.

4.MERCATOR PROJECTION

It is often described as a cylindrical projection, this projection is created based on mathematical operations... This projection is usually used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. It is less practical for world maps because the scale is distorted.

5.AZIMUTHAL PROJECTION

The azimuthal projection consists in projecting a portion of the Earth on a plane tangent to the sphere at a selected point, obtaining the vision that would be achieved either from the center of the Earth or from a poing in space outer. The azimuthal projection is a projection geographical characterized by radial symmetry around the center point. In this kind of projection we can find different types such as: orthographic, stereographic, gnomonic, equidistant...

TASK 2

HOW WE DO IT?

We start a new week with a different role and with a different task, Task II.This task will be related with the different kinds of maps proyections we can have ( Robinson, Mercator, and Azimuthal), the concept of distorsion and tresure hunt, and we have related this task with the slogan "Media is not neutral".We started working on this neww task about map proyections since Monday. We organize the work and at the end of the class we shared the information that we had obtain. Our stars have meet via Skype to organize and get a better presentation of our work. To show the work we did we have created a presentation via powerpoint and we have also create a handmake poster that shows the differences between the three kinds of maps proyections.

All went well, and the work was on time. On Wednsday our stars did an excellent work in the exposition and we think that the people enjoyed . Here is a photo of the presentation and one of the group just after finishing the classroom activity.

The Analyst work:

During this task we´ve improved our capability of working together and the academic relationships between us. In my opinion, the best part of the activity was the coordination between us, how each member of my group did its part of the job and how we helped each other. In contrast, the worst part was that we did the presentation for two stars and finally we had to improvise to reduce that two stars´ screenplay in only one. Equally, the best moments of the week were the coordination and the solidarity of the members of the group during the realization of the task and also the nerves and the exciting atmosphere of the first presentation. The worst moment of the week was that we could only use one star instead of the two that we thought. I have learned the utility of TPACK as a useful tool for my future work as a teacher and the different types of information maps that I can use to organize and present some information. We need to conserve our solidarity and responsibility with the group for future tasks and the talent and originality we have. We need to improve our presentations and the information that we find on the Internet, it has to be more extensive and reliable. This content is related with other contents of this course because it also has the aim of find new ways and new tools of being better and more accurate in our tasks. This content also has a social connection because it´s related with the importance of technologies in our society nowadays and how they can help us to get better our lives, our works and so on.

The Translator work:

1. Speed learning
It is methodology to learn fast. It is the basis of every learning is interest, It's the key to learn effectively and fast, but there are many other factors that influence speed learning. For examples having a good diet, doing exercise, not smoking and not drinking may help learning fast. Also are useful things that keeps our brain active, like colours when we study, otherwise the brain can go off and lose crucial information. For instance, the way we have made our presentation of TPACK with information maps help speed learning because it integrates a visual ideas of the concept. It's a combination of procedures that enables you to achieve some goals.

2.TPACK
TPACK is an acronym composed by the words technology, pedagogy and content. It refers to a model to understand how to teach, It is a framework that includes inside macro and micro context of influence three different kind of knowledge and the interactions between them. These are content knowledge which is the mastery of the subject, pedagogical knowledge which is how to master it, and technological knowledge which integrates the use of technology in the context.

3. Information map.
It's a tool that enables to organise and representate in a graphic way and through an schema, the knowledge. It has it basis on theoretical approach of educational psychology. The objective of a conceptual map is to representate relations between different concepts that acquire the shape of propositions. The concepts usually appear inside circles or rectangles, while relations between them are manifested with lines that match each circle or rectangle. At the time to develop an information map is fundamental to follow a series of steps to reach the objective to show a fact in a clear and simple way. There are many types of information maps: Spider concept map, hierarchy concept map, flowchart concept map, system concept map.

4. Diagram
is a graphic representation of all the steps that forms a process. It is an esquematic representation of the succession of operations that compose a system. Every actions, is this sense, are interrelated to produce a specific result. Diagrams are very useful to express process of work, design, learning processes... They can be applied in different fields like education, economy, mathematics, psychology and so on. There are many types of diagrams: horizontal, vertical, architectonic and panoramic.

5. Concept:
concept means design, construction or symbol, conception, idea or opinion expressed, characterization. It's the formulation of an idea or a image through words. It means something conceived or formed in the mind, it’s considered a cognitive unit of significance. It is formed in the mind about something or someone and consists of a type of evaluation through an expressed opinion. It’s also a mental symbol, is an abstract notion that contains every word of a determinate language and correspond to a group of common characteristics to a kind of thing, objects or abstract entities, determine how things are.

The truth is that I didn’t imagine that it would be like that, I had never made a presentation as well. I was very nervous because we were two stars and I was afraid of that because I wouldn’t be wrong when I started explaining it.

The Star:

TASK 1

The process to do it:

Today we have just started with our first task. We hope that we do it right!!

Well, in this first task we’ve had to look for information about TPACK. For doing this first task we have had to search six types of information maps and choose one in which, the teacher said, we had to put the answers of the four questions that she sent to us about TPACK. So we have chosen a spider-gram.

For doing this task, everyone started to read some pages about TPACK and we tried to understand what TPACK was etc. Then we distributed the questions pair groups of two people in order to do it faster. After that we sent the answers to our group Gmail.

The Star put all the questions in the order that he wants, he made a scheme to prepare it for the exposition, and he sent it to the other members to read it and understand the concept. Also we decided to see some videos in YouTube for example, Linda’s video, in order to have the idea clearer.

Silvia found a good page for doing main maps and Eric decided to do it for trying it. But when we tried to photocopy it, we couldn’t see properly the words because they were too small. So we decided to use the same style as Eric used in the web page, but we print it in parts and bigger to better understand the words.

When we finished all the things that we have to put in the poster, we did two posters, firstly we were confused about that, but then it was funny and we brought both to class because in one of them we put all the things in one page and in the other we put the different answers in the front and behind the poster to see all the things clearly and more separate, so it was better for our classmates to see the concepts that we wrote in the poster.

Finally on Wednesday we had to show our assigment to the classroom, and we really like the way we have to do it, because it was a different dinamic and we found it really funny. Linda said to our star the things that were wrong and the things we have to improve, so we have learnt about this task that we have to communicate each other better in order to prevent these mistakes and we hope that the next task works better. Good job team! And thank you David for being our first star!
