The application requires less than kB of free space to be installed. User interface shows also a new approach: simple and intuitive, no matter how much computer fluency the user has.

For example, the pencil tool is automatically selected when the application starts. Each tool has a set of options embedded in its palette, which provides advanced controls like filling or not a closed shape and determining line thickness. Further on we describe the most important geometry-related tools. When the mouse button is pressed and held, the tool draws free hand forms and when the mouse is clicked moved and clicked again, a straight line is drawn between the two points.

When the student clicks again on the starting point, the drawing is completed and closed. Thus, irregularities can be put into shapes, creating a large universe of possible drawings, extremely useful for non-regular shapes of world representations.

The illustration bellow shows a completed free form drawing; it has a filled image, but it could have outline only. Example of free-form polygon, user is able to draw lines and free-hand curves in the same shape.

During the creation of the figure users can define its size and also rotate it in some cases. The following illustration shows the advanced controls available for the regular polygon: line thickness, number of sides and filling. Figure 2. Advanced controls accessed through a palette for regular polygons Shapes are drawn when the user presses the mouse button, holds and drags it.

The combination of special keys while drawing a shape allows more flexibility. If the user presses the ALT key while drawing a shape, the system moves it to anther position. If the user presses the CTRL key, it will be rotated. If the user presses the SHIFT key, the application will draw a regular form: a circle not an ellipse , a square not a rectangle. Basic shapes the Oficina offers are: circle, rectangle, line, regular polygon user chooses the number of sides , heart, parallelogram, arrow, star user defines the number of vertices , trapezoid and triangle.

OLPC's decision was to develop all operating system graphical interfaces named Sugar using the Python programming language. For a complete integration between our software and Sugar, Oficina was implemented using this language. Python is an object oriented programming language with a very simple and comprehensive syntax, facilitating code programming and understanding. To run software in python it is necessary to have an interpreter. One peculiar characteristic of this language is the obligation of indentation, because this serves as a delimiter of code blocks.

One of the advantages of python is the great amount of existing. The development team adopted Extreme Programming practices, especially those that are focused on teamwork and communication. According to Jeffrey , communication is very important to agile software development. Thus, person-to-person communication was encouraged and weekly meetings were conducted. As of documentation, main functions are commented and explained in a class diagram.

Coding standard is another inheritance from extreme programming, as all development is done using Python, every programmer in the team uses the same indentation and naming conventions.

This is important because of the collective coder ownership, which means everyone is allowed to change the code anywhere. To avoid conflicts, the team has to be constantly updated. A key practice used to write Oficina is pair programming, developers do not solve problems and create new features alone, and this helps improving communication and uniform programming styles.

As tests are also important, Oficina receives bug reporting on a public system from all over the world, since the OLPC testing team is worldwide. Finally, we used a distributed version control system, named GIT. It maintains the development history inside of each local copy, proving an easy way to merge local and remote branches Baudis. Although it has associated learning difficulties, GIT's version control capabilities make it the right tool. These experiments were intended to collect some first impressions and suggestions of improvements and new functionalities.

In the first step, the XO laptops were given to the teachers and they ran and explored the Oficina by themselves. This exploration took about 30 minutes and during it some notes were taken. In the second step, a questionnaire was applied with the following questions: 1 How is drawing expression related to your discipline? Did you have any difficulty while using a tool or a feature?

If positive, give some examples. These tests evidenced that the software is adequate for an educational use, especially for supporting different knowledge areas and allowing interdisciplinary activities.

Another example of interdisciplinary activity, is the conception of a product advertisement, including planning, text elaboration, and final art.

In this case, children would work three skills: artistic, textual expression and logical thinking. Tests also revealed some potential difficulties users found. For example, the color selection and the free polygon were reported as non-intuitive features.

Teachers mentioned they liked geometric shapes because of the options that can be explored with the kids, not only in Mathematics; a teacher mentioned the two- dimensional representation of solid objects 3D as a possible activity. If children take laptops home, the required homework would be to take pictures of the environment and modify them to build new scenarios.

Also more alternatives of educational uses, especially in classroom utilization, will be explored and searched with the teachers.

As the XO laptops connect to each other using the Mesh Network then, we plan to develop a collaborative mode of the Oficina.

From the technological point of view, Oficina made possible advances in the development of graphical programming techniques using the Python programming language.

The major software's differential is to have been developed for low cost educational laptops which has many limitations in terms of its computational power, being a very light weight application. Still, Oficina brings a new way of working with Geometry, giving students and teachers possibilities to more powerful world representations as well as new expression tools.

Oficina can also empower world representation by integrating with it the embedded camera present in the XO; it can amplify exploration possibilities by adding a picture to a drawing.

This kind of software can reach a large number of users among students and teachers, since governments of different countries want to distribute low cost laptops in large quantities. J Org. Aprendizagem colaborativa: o professor e o aluno ressignificados. Baudis, P.

Access in November 15th, As the teachers were unable to explain what had happened, it was necessary for us to intervene. O Cara! Another aggravating circumstance in probability teaching, according to Batanero et al.

So any student will be able to write a program without much effort. Still, the main development focused on a simple interface and a lightweight application. The probability of the needle In the fourth sequence, we performed Buffon's needle experiment, in which a needle of length l is thrown crossing a line is asked for see also Tunala, ; we employed geometrical and probabilistic concepts to estimate this probability.
