LEO is a system that supports and strengthens the teaching tasks of the educator in the field of literacy with preschool children between 4 and 5 years in a multicultural setting. It is based on the phonetic method of "Letrilandia" (Usero, 2004).
It allows the teacher to create exercises of different types (letters, syllables, words and phrases) quickly and easily. It has two working modes: learning mode and evaluation mode, with which students can learn in a group or be tested individually, respectively.
The system is equipped with a multitude of multimedia resources (audio, video, graphics, voice, drawings, blackboard, etc..) and it can run in numerous technological media (computer, Tablet-PC or touch screen).
The system includes two main roles: teacher and student.

Teacher

The following diagram shows the different actions that a teacher can do.

Configure session options

The work session is characterized with the configuration of certain parameters such as class, mode and position of students. These parameters must be specified before starting the work session and if not, el system will display a message advising configure the session and refuse to start working anyway.
To access the screen that you configure session options is necessary to click on the toolbar above the menu Session.



After that, it displays the dialog box with which you configure session options.



In the dialog box you can see that there are three options to choose from:

1. Class: this option will indicate the particular class with which you will work (4A, 4B, 4C, 5A ...). When loading any exercise, you will see a mosaic of photos of students of selected class.
2. Mode: with this option you will selecte the mode or scenario with which to work on. You can select between Single, Group, or All.
3. Position of students: this parameter specifies the location of the screen (top or bottom) which will be shown, during the exercises, the mosaic with the photos of students.

After selecting the desired type of exercise, will be charged a new window. It will show all the existing exercises in the system and belong to the type of activity selected in the previous screen.



When you have chosen the name of the exercise you want to delete and click on the button Delete, will appear several messages for that the user confirm the action you are about to perform.

Create evaluation session

An evaluation session is formed by a serie of sets of predetermined exercises, such sets will be assigned to the students you want. These will be presented to the student for do alone and independently.

To create an evaluation session must go to the menu Settings in the toolbar and click on the option Session Evaluation >> New Session.

To create a evaluation session is necessary to perform the following two steps:

1. Assign sets of exercises to the pupils that you want.
2. Establish for each pupil, the order in which exercises of each group will be showing.
   
   

Assignment of exercises to pupils

The interface that the teacher has to perform this step is the following:

    //Captura de la ventana del editor de sesiones de evaluacion//

The teacher should assign an identifying name to the session. He also needs to specify whether the session is active or not, that is, if you want that the session that you're creating is available for that the students perform it.

The window has two data filters through which the teacher can work more comfortably and handle only information that is useful:

1. Class: The teacher should choose the class (4A, 4B ,..., 5C) with which he wants to work. By selecting one of them will be loaded a list with photo and name of pupils who belong to that class.
2. Type of activity: the teacher can choose the types of activities with which he wants to work. By selecting the desired types will display a list of exercises belonging to the selected types available in LEO.

To make the assignment of exercises to pupils, only the teacher should click on the pupils of the list that he wants and then select which exercises that he wants pupils perform it. If the teacher wants to assign to a group of pupils the same set of exercises will not have to make an assignment for each pupils, but can simply make the assignment once because the system can assign exercises both to a single pupil as to a selected group.

The window also has several points of information, through which summarizes the assignments that have been made:

1. Pupil information: next to each pupil of the list there is a button that when is pressed will display a screen with a summary of the exercises that have been assigned to that pupil.
2. Exercise information: next to each exercise of the list there is a button that when is pressed displays a window that lists all the pupils who has been assigned this exercise.

         //captura venetana información alumno//  //captura venetana información ejercicio//

Finally, in the bottom of the screen there are three control buttons:

1. Sequence Button: When you click on this button will go to the 2nd step of creating of an evaluation session. Make sequencing is optional. If not done, the exercises will take the default order that corresponds to the order in which they are assigned to pupils.
2. Accept Button: clicking this button, the system stores the session that being created. If in this window, you click on this button, you accept the default order of the exercises.
3. Cancel Button: Pressing this button cancels the creation of the evaluation session.
   
   

Establish order in the exercises

This step in the creation of an evaluation session is optional. If not done, the exercises will take the default order that corresponds to the order in which they are assigned to pupils.

The teacher has the following window to order the exercises:

                     //Captura del secuenciador de ejercicios//

As can be seen, on the left side of the screen displayed only the pupils who have been assigned some exercise. Clicking on any of them, loaded in the right side of the screen a list with the assigned exercises to that pupil. The shown exercises have the default order. By the arrows shown on the right margin of the screen you can specify the desired order of the exercises.

Finally, in the bottom of the screen there are two control buttons:

1. Accept Button: clicking this button, the system will save the session that is being created with the sequences of exercises that has been specified.
2. Cancel Button: Pressing this button cancels the creation of the evaluation session.
   
   

Delete evaluation session

To delete an existing evaluation session must go to the menu Settings in the toolbar and click on the option Session Evaluation >> Session Delete.



Next, a new window will display all evaluation sessions stored in the system.



When you have select the name of the evaluation session you want to delete and click on the Delete button, several messages will appear for that the user confirm the action you are about to perform.

Select work mode

To select the mode you want to work you must go to the menu work mode from the toolbar and choose one of two available modes in the system.



These two modes are Learning Mode and Evaluation Mode and differ in the way that the exercises are presented to students and work scenario that conducive.

• Learning mode: the use of this mode is designed for that all students of one class perform the exercises in a joint way namely, a student completes the exercise with the presence of their classmates and in this way, all students learn at the same time although only one student do the exercise. To achieve this environment is necessary to use a Smart Board as show in the image on the left.
• Evaluation mode: with this mode is intended to test the knowledge that the student has acquired during the learning sessions. The ideal work scenario for this mode is where the student do the exercises alone, without the presence of any classmate. For this mode, it has been thought to use as support a Tablet-PC as shown in the image on the right.

Learning mode

By selecting the learning mode, a new window will be shown through which you will choose the group of activities with which you want to work. These groups are distinguished by the linguistic unit with which you will work (letters, letters-words, syllables-words, words, words-sentences).



Depending on the choice made, the system will give the possibility to practice with certain types of activities. The following summary shows the available activity types depending by the selected option.

Screen of sessions

The appearance shown in this screen is as follows:

      //Captura pantalla sesiones//

This screen shows a list of all sessions that were assigned to the selected pupils in the previous screen. These sessions appear ordered by date of creation, newest to oldest. Note also that there is a color code to distinguish at a glance the different states in which a session can be.
