agustinMy name is Agustin Carrillo de Albornoz Torres and I am a Secondary School Mathematics Professor. At present I am working at the University of Cordoba (Spain), I am the director of GeoGebra Institute in Andalusia.

I am involved in working with various associations of professors and I am the chief secretary of the Spanish Federation of Teachers of Mathematics (FESPM) and the American Federation of Societies of Mathematical Education (FISEM).

When did you first try GeoGebra?

I started using GeoGebra in 2005. At that time I was coordinating a project on the integration of ICT in teaching in “Jándula Secondary School” which involved to provide computers for the whole school. Among the available programs to use in the classroom, it was GeoGebra. As I had some experience with dynamic geometry programs, I encouraged myself to find out what GeoGebra could offer.
In 2009 I published the book “GeoGebra. Much more than dynamic geometry ” whose aim was to offer some materials that could encourage and help teachers get started with GeoGebra.

How could we make GeoGebra even better?

It is not easy to answer this question because in each new version of GeoGebra we find significant improvements, as we have seen it with the addition of CAS or as it will happen with the 3D version.
In relation to the CAS version, I consider it still has to incorporate some commands and options to increase its power and in terms of the 3D version, I hope that we will soon enjoy the final version.
I also hope that versions for tablets and phones, which will make us have GeoGebra ready in our hands, will be available soon.

What do you love in GeoGebra?

Although all aspects of GeoGebra are remarkable, what I like most is its simplicity , which makes it so easy to use as it is such an intuitive program.
In addition, the ease offered by Geogebra to match levels or contents at any time they are working, make us consider it as an essential tool for all teachers who wish to incorporate ICT into their classroom.
Another noteworthy aspect is the community which has been created with millions of users willing to share materials and experiences, making it easy to use and ,above all, the power to solve any questions or problems quickly.
And finally, I also like the continuous evolution of GeoGebra, which forces as well as encourages us to discover the possibilities the new versions incorporate.

What are the GeoGebra related activities you participate?

From the GeoGebra Institute of Andalusia, I have taken part in the organization of meetings and conferences convened since its creation, which took place in Córdoba (2010 and 2013), Huelva (2011) and Granada(2012).
For many years I have participated in face-to-face and online teacher training courses in the use of ICT resources, including GeoGebra, promoting their use and encouraging teachers to their incorporation and use in the classroom.
This training is completed with various workshops and lectures at conferences and seminars held in Spain and Latin America.
Taking advantage of being the chief secretary of the FISEM ,I take part in all activities that the associations that belong to the federation call to promote and spread the use of GeoGebra.
Furthermore, in collaboration with the Organization of Ibero-American States (OEI) I participate in the development of materials and resources to use GeoGebra , which are being used in online training courses.
Also, in collaboration with the OEI and its American Institute of ICT and Education (IBERTIC) we have called “GeoGebra Day in Latin America” which will take place in Montevideo on September 14 as a previous activity to CIBEM .

GeoGebra Ambassador #10 https://blog.geogebra.org/2013/06/geogebra-ambassador-10/ https://blog.geogebra.org/2013/06/geogebra-ambassador-10/#comments Wed, 05 Jun 2013 11:47:12 +0000 http://www.geogebra.org/blog/?p=652 ]]> Talgat BainazarovWho are you, what are you doing?

My name is Talgat Bainazarov. I have been teaching mathematics in secondary school. At the moment I am a vice-principal at newly opened Nazarbayev Intellectual School in Karaganda.

I am the translator of GeoGebra UI into Kazakh (my native language) and the Chair person in the GeoGebra Institute of Astana

When did you first try GeoGebra?

I first tried GeoGebra in 2009 when I was a university student on a workshop for prospective teachers held by a public school. Since then GeoGebra has become a good friend of mine.

Year 2009 was just an introduction. I didn`t go deep into it. A great impact on my enthusiasm was made in 2011 by the first GeoGebra ambassador Guillermo P. Bautista Jr. I came across to his blog when I was searching for step-by-step tutorials. I learned a lot from his tutorials in his wonderful blog Mathematics and Multimedia.

He brought me an idea of establishing a local GeoGebra Institute (there are 3 in my country now). After having learned to use GeoGebra step by step, I started to produce videotutorials and presentations in Kazakh.

What do you hate in GeoGebra?

The only thing that I feel pity about is that 8 years had past for this wonderful software to reach me. I wish I had known and used in my study at school.

What do you love in GeoGebra?

I love people in the GeoGebra community. All of the members of team are so responsive, enthusiastic and helpful that newly involved people in the community are easily “infected” by their passion to spread dynamic tool for mathematics to everyone. I have students, who in some way have become teachers, in the GeoGebra Institute of Astana, because they are making video, presentations and translations. They have created a public page on a social network.  They are sharing their knowledge and ideas. The feeling of contribution in the education has been driving them ahead. I guess, the same can be told about all the students around the world who are involved in the GeoGebra community.

What are the GeoGebra related activities you participate?

  • The first activity is the workshop for maths teachers that I led in my hometown Kostanay in 2011
  • The next year AEO “Nazarbayev Intellectual schools” invited Zsolt Lavicza to Astana for the August conference and a two day workshop. I assisted him on the workshop
  • In May, 2013 we hosted Zsolt Lavicza and Istvan Juhos for the workshop. This visit was very productive, because we managed to meet a lot of important people who became more interested in the GeoGebra. We are expecting good changes in the development of mathematics in Kazakhstan.

My name is Mehdi Boulifa.  I am a teacher of mathematics in Tunisia. I am passionate about music, informatics and sport.

I created a website: www.monmaths.com and blogs in all the regions of Tunisia.

My blog is called GeoGebra in Tunisia.

When did you first try GeoGebra?

It was in 2008. I tried to create files to use GeoGebra in class afterwards.

What do you hate about GeoGebra?

Nothing. Perhaps, java can be slow in opening   html files.

What do you love about GeoGebra?

What I like about GeoGebra is: first it is for free. It facilitates the way we teach in class.  It has great tools educationally. Possible GeoGebra5 version goes even easier to use with its new features. GeoGebra is synonymous with sharing.  There is a wonderful forum which provides excellent support. All the more, it is shining all over the world and this can help the teacher to better  teach  mathematics to learners.

What are the GeoGebra related activities in which you participate?

  • I am the president of The Institute of GeoGebra in Tunisia which is the first in the Arab world and the third in Africa.
  • In September 2012 I attended the international conference in Warsaw GeoGebra
  • We are at the moment and with the help of school inspectors currently working on a program of training colleagues in all regions of Tunisia (http://wiki.geogebra.org/en/2012_Annual_Report_GI_TUNISIA  )and also we are now preparing certification for teachers (one program for month of March a caravan of training to go to remote areas and particularly in the south)
  • We update the translation software in Arabic
  • I hope that through our work at the Institute, we will eventually integrate GeoGebra activities in our textbooks, and achieve an international conference on GeoGebra Tunisia.

GeoGebra Ambassador #8 https://blog.geogebra.org/2012/12/geogebra-ambassador-8/ https://blog.geogebra.org/2012/12/geogebra-ambassador-8/#comments Fri, 21 Dec 2012 14:33:39 +0000 http://www.geogebra.org/blog/?p=405 ]]> Who are you, what are you doing?
My name is Fabián Vitabar. I am a Maths teacher, from Uruguay. I work in a teachers training institute in Montevideo (IPA), I teach those who will be high school teachers.
I am really interested in Mathematics Education, specially in how can teachers help students to learn Maths. I think that GeoGebra is a wonderfull tool, but we still have to learn how to use it in the best way to reach our goal.

When did you first try GeoGebra?
It was in 2005. Someone talked to me about a new open source project involving dynamic geometry, and I tried it at home that night. I felt it was interesting and promising, but it wasn’t enough yet for my high school students. My sense changed soon. I followed each version since that year, and nowadays I use it more and more in my classroom.

What do you hate in GeoGebra?
There is something I really hate: GeoGebra is always giving me a challenge. It makes me think about my lessons, It makes me doubt about what I do in the classroom, or even about what i’ve been doing for many years and I never asked myself about. I can’t give a lesson just as I did it in the previous course, because I get a new idea using GeoGebra and I can’t avoid it: I have to plan a new lesson. I hate GeoGebra because It leads me to a permanent didactical thinking.

What do you love in GeoGebra?
I love that it’s always surprising me. There is always something new. But the most I love is it’s so easy for my students, and they love it immediately. They start working on it, and in a few minutes they are learning mathematics, playing, exploring, and teaching me! It’s amazing.

What are the GeoGebra related activities you participate?
I am the chair of the GeoGebra Institute of Uruguay, and I lead the Laboratorio GeoGebra experience in Montevideo, offering workshops and courses. We’ve recently hosted the annual Latin American conference in our institute, and I’m trying to keep in touch with every colleagues in our region. GeoGebra is growing really fast, too much people want to know about GeoGebra, and I’m doing my best for show them why it delights me.

I am Anthony C.M. Or from Hong Kong. I was a secondary mathematics teacher for many years and is now a curriculum development officer in the Education Bureau. My major duty is to develop some learning and teaching resources in Mathematics to cater for the learning needs of students at primary and junior secondary levels. I also conduct studies with focuses on how to improve learning and teaching of mathematics, and organize seminars and workshops for teachers.

When did you first try GeoGebra?

I first tried GeoGebra 3.0 in 2008 and found it a wonderful dynamic geometry software. Since then, I use GeoGebra a lot to develop learning and teaching materials.

What do you hate in GeoGebra?

I have nothing to hate in GeoGebra. I would love it more if its functions of text formatting can be further enhanced.

What do you love in GeoGebra?

I love its dual (Graphic and Algebraic) modes of representations and constructions. I love its powerful commands, scripting and the conditional showing of objects. I love the flexibility it provides such as the customizable toolbar and Java-based HTML output. I love its nice Graphical User Interface. I love GeoGebraTube. Finally, I love the freeness of GeoGebra, not only in terms of price but also in terms of the liberty to implement my ideas freely.

What are the GeoGebra related activities you participate?

I am a co-chair of GeoGebra Institute of Hong Kong. We organize GeoGebra workshops for teachers. We also develop websites to foster the use and sharing of GeoGebra materials suitable for Hong Kong curricular.

GeoGebra Ambassadors #6 https://blog.geogebra.org/2012/11/geogebra-ambassadors-6/ https://blog.geogebra.org/2012/11/geogebra-ambassadors-6/#comments Thu, 22 Nov 2012 22:36:58 +0000 http://www.geogebra.org/blog/?p=358 ]]> Micky Bullock is our youngest GeoGebra Ambassador. He tweets a lot about GeoGebra and uploads great materials to his GeoGebraTube account.

Who are you, what are you doing?

Micky Bullock. I teach mathematics at Forest School, an independent secondary school in London. I teach children from the age of 12 all the way up to the age of 18 including A-Level Further Mathematics.

My blog is called The Secret Garden of Maths (www.mickybullock.com). I use it to showcase GeoGebra apps and share solutions to interesting problems. Do take a look!

I’m interested in how I can use computers to enhance the experience of learning mathematics in school. I frequently employ GeoGebra in the classroom and try to teach the students how to use it. I write GeoGebra apps in my spare time for whatever mathematical need takes my fancy. I’ve created apps about probability, projectiles, differential equations, binomial theorem and expansions, just to name a few, and I’ve recently finished the Easy Mortgage Calculator. I always aim to make the apps as ergonomic, aesthetically pleasing and accessible as possible. I also try to make them unbreakable, for example ensuring you can’t lose points off the side of the screen or combine parameters in a way that makes the equations break down when they shouldn’t. My main aim, though, is to allow the user, whoever they are, to learn a mathematical concept simply by playing with the app. It’s fun, but my perfectionism sometimes keeps me up all night!

When did you first try GeoGebra?

I remember seeing a link to GeoGebra on the desktops in my first placement school when I did my teacher training at the University of Leeds in 2009. My first glimpse of its potential was in January 2010 during a university workshop on maths software. The member of staff drew a triangle, constructed that triangle’s circumcircle and inscribed circle, then started dragging the vertices of the triangle around. I watched as the circles moved smoothly and resized continuously. It was beautiful to watch and it seemed to open up a floodgate of creativity in my mind. My love of GeoGebra had begun. Since then I’ve been tinkering with it almost daily.

What do you hate in GeoGebra?

  • There’s a huge difference between small and medium font size. Also the text isn’t intelligent, for example if you set it up to show y=mx+c, with m and c numerical parameters, when c is negative it will say, for example, y=3x+-2. Or if m is zero it will say y=0x+-2. We wouldn’t normally write this. There are workarounds but they are fiddly.
  • The spreadsheet can be slow and cumbersome when there is a lot of data.
  • I can’t get it to automatically write information to specific cells in the spreadsheet.
  • When people share rubbish apps on GeoGebraTube.

What do you love in GeoGebra?

  • It’s open source.
  • It’s free.
  • It’s delightfully easy for students to use in a basic way
  • You can create interconnections between all sorts of objects and you can attach variables to things like the view window and the RGB and opacity.
  • Boolean algebra in the “Condition to show object” field
  • GeoGebraTube for sharing apps
  • I also love how fast it is being developed. GeoGebra is taking over the world!

What are the GeoGebra related activities you participate?

  • In November 2012 I attended the Computer-Based Maths Education Summit at the Royal Institution in London.
  • In October 2012 I gave the opening keynote address at the X Jornades D’Educació Matemàtica, a conference at the University of Alicante. The talk was entitled, “The Value of Dynamic Geometry in Modern Education and Problem Solving in GeoGebra”
  • I’ve given talks at the MEI (Mathematics in Education and Industry) conferences in 2011 and 2012 on use of GeoGebra in education.
  • I’ve given talks at the MathsJam conference in 2010, 2011 and 2012. In 2010 my talk was entitled, “Playing Lemmings with Discontinuous Functions” and in 2012 I generated a profane graph that swears at the viewer.
  • I attended ICME-12 (The 12th International Congress on Mathematical Education) in Seoul, Korea in July 2012. Here I met Balazs Koren and Zsolt Lavicza. I was surprised and excited to see one of my own apps used in a demonstration of GeoGebra such a long way from home.

My name is John Golden, I’m a mathematics education prof at Grand Valley State University, in western Michigan, USA. I teach future K-12 teachers, mathematics courses, and mentor student teachers.

When did you first try GeoGebra?
Fall 2009. I loved dynamic geometry, but had very little use from my students other than what I asked, since their access was limited. An open source program was a dream come true.

What do you hate in GeoGebra?
Nothing! I miss recursion a little bit, and wish the custom tools were a little more flexible, but new features get added literally faster than I could wish for them.

What do you love in GeoGebra?
So many features to love. The heart of it is the strong connection between geometric and algebraic representations. As an application, the unbelievable ease to get a new user starting is amazing.

What are the GeoGebra related activities you participate?
I use GeoGebra with students, both as a super-calculator and geometric constructer and for created activities. I help train teachers to use the program, and support local and web users via email and Twitter (@mathhombre). I use it for my own mathematics solving, and just to play.

I am Juan Pablo Serrano Echeverría. I am a math teacher who works as a national math adviser in the Department of Production and Management of Technological Resources, Technological Resources Direction, Ministry of Public Education, Costa Rica. I work making materials and giving workshops and videoconferences about the use of the ICT as an methodological instrument to improve the teaching and learning processes in mathematics. GeoGebra is my favourite software to do all of that.

When did you first try GeoGebra?
About 9 years ago, I was looking around the internet seaching for Java applets for my lessons. I was working in that days with Winplot and Wingeom, but I wanted a software which works in the web environment. And so, while looking and surfing the web… I found Geogebra! It was love at first sight. I began with version 2.5, then 2.6a, 2.6b and the others.

What do you love in GeoGebra?
I love everything!
If I have to choose one, I will say that the slider objects and the exportation as a web page what the first thing I love about GeoGebra. Now, the scripting features are something I am crazy about.
Geogebra is great and I like all the capabilities it has.
The spirit of Free Software is something I like very much.

What are the GeoGebra related activities you participate?
I worked in my country for a project about geometry, for the first level in highschool. We are using GeoGebra.
I participated giving two conferences and one workshop about GeoGebra in an International Math Festival in my country. At end of July and beginning of August I am going to participate as a plenary speaker at the 3rd North American Conference in Mexico and at the Latin American Conference in Colombia.
When I return to Costa Rica, I will organize and participate at a videoconferences cycle, for Central America to encourage people to use GeoGebra.

Who are you, what are you doing?

I have been a secondary school mathematics teacher at Madeira High School in Cincinnati, Ohio, USA for the past 22 years. I have also been a Mathematics Instructor at the University of Cincinnati Blue Ash College in the Department of Mathematics, Physics, and Computer Science, as well as in the College of Arts and Science in the Mathematics Department for the past 10 years.

When did you first try GeoGebra?

I read an article by Markus on the Mathematical Association of America website in March of 2007. I have been using GeoGebra since that day. What was the “thing” that got me started? I was AMAZED how simple it was to do calculations with coordinates ( for example, x(A)+y(B) ). It was so difficult to do in other software 😉

What do you hate in GeoGebra?

I am not sure there is anything I hate in GeoGebra. There are some “I wish…” I think from time to time, you need to be a little “tech savvy” when in the rare instance a java issue crops up. I wish this was not the case. I think this can scare folks from time to time.

What do you love in GeoGebra?

How can I pick just one thing? Dani Novak from Ithaca College told me that he didn’t care if others used GeoGebra. He used GeoGebra because it made him happy. That is why I love GeoGebra…It makes me happy!

What are the GeoGebra related activities you participate?

I am the co-Founder and co-Director of the GeoGebra Institute of Ohio (GIOHIO), which was the first Local GeoGebra Institute in North America. We have organized the Midwest Regional GeoGebra conference for the past 2 years (attracting over 350 total participants) and will be hosting the 4th annual North American Conference in 2013.

On behalf of the GIOHIO, I run free GeoGebra workshops for teachers during the summer, as well as run free monthly GeoGebra workshops during the school year. I also share GeoGebra at State and National teacher conferences.
