Two specific applications have been developed by the Aristod Company (http://www.aristod.com):

(1) a player called Aplusix Web implemented in JavaScript, running on computers, tablets and smartphones;

(2) an authoring tool which is an extension of the EpsilonWriter software, running on computers.

The authoring tool is used by teachers to generate Aplusix exercises (http://epsilonwriter.com/en). They have to enter lists of exercises, each exercise having a type of exercise (Calculate / Expand and simplify / Factor / Solve equation, inequality, simultaneous equations) and a formula. An advanced formula generator is used for producing many exercises form a pattern. Teachers can easily type 5 patterns, generate 100 exercises from each, and set the file to provide randomly 10 exercises to the student. Files are stored on a web server to be available immediately for everybody.

The player is currently a web app running in a browser (http://aplusix.org) and using the Training mode described above. During the beginning of 2016, a Test mode with scores and feedbacks at the end of the activity will be added. Standalone apps will be developed for Apple Store and Google Store. They will be usable offline, containing the player and many exercises.

The first experiments in secondary schools of this new app, on tablets and smart-phones, are encouraging. Aplusix Web helped them to work their technical knowledge on algebraic expressions and equations in a pleasant context: “We like to work with this digital device. We feel more motivated. It’s much more playful than a textbook.” The feedback allows them to train in autonomy in the classroom and at home, and highlights misconceptions, for instance: 3x=1 is not equivalent to x=1-3 and 4(x-3) is not equivalent to 4x-3. From these feedbacks, students either ask the teacher why it is not equivalent, or correct themselves without any intervention. We noticed an improvement in their skills.

In conclusion, Aplusix Web appears as an efficient tool enhancing students’ autonomy like its predecessor (Chaachoua & al., 2004) but also now as a practical and funny tool usable everywhere at any time because many secondary students own a smart-phone.
