Software for learning arithmetic and algebra

Aplusix is an innovative software, developed by the Laboratoire d'Informatique de Grenoble to help students learn arithmetic and algebra.

Aplusix reinforces students' skills, reduces mistakes in their working out, and shows students how to solve exercises.

Good arithmetic and algebra skills are necessary for further studies.

Aplusix is an excellent addition to school and extracurricular training. It can be used independently or with the guidance of a teacher or a tutor.

News of version 3.1 (September 2012)
Possibility of installing Aplusix on an USB key besides the computer.
Possibility of adjusting the font size (help to the partially-sighted persons).
Possibility of parameterizing the companions.
Improvement of printing, and possibility of making a pdf files.

Aplusix modes

In Practise mode, the students solve questions by performing their own calculations. If they don't know what to do, they can request a companion to make a suggestion or a calculation step. Aplusix automatically verifies the students' calculations and the completion of questions.

In Test mode, students work for 30 minutes without any feedback. At the end of the test, they get a score and can enter Self-correcting mode.

In Self-correction mode, students review their own work. Correct and incorrect calculations are clearly marked and they can see whether they have completed the question or not. They can correct their calculations with the same level of feedback as in Practise mode, including the use of companions.

In Review mode, students review their work. Correct and incorrect calculations are clearly marked and they can see whether they have completed the question or not. A replay system is also available to them.

Many exercises, covering most aspects of the Number and Algebra strands of the UK National Curriculum and a lot of the algebraic content of Foundation and Higher GCSE, allow to practise, understand, and become efficient: numerical calculations, expansions and simplifications, factorising, solving equations and inequalities, simultaneous equations.

In addition to the provided exercises, it is possible to do homework and to practise with exercises given by the teacher (e.g. from textbooks or worksheets).

Scientific experiments led in several countries, under the control of mathematical education researchers, have shown that with Aplusix students work more, become self-confident and independent, and improve their skills.

The student asks the companion Chloe to perform a calculation step.

Chloe (12 years) makes some small steps and explains them.
The Map allows choosing exercises.

Each dot is a family of 10 questions of the type indicated on the left.
The colour of the dot indicates the difficulty level.
The student correctly solves a simple equation.

The two black straight lines indicate that the calculations are correct.
Here, the student has made an mistake.

The two red straight lines indicate an error.
The student asks the companion Julien to suggest an expression.

Julien highlights an expression that it would be useful to work on.
The student asks the companion Julien to suggest an action.

Julien describes the proposed action.
Action suggested by Julien in the following step.

Of course, it is at the request of the student.
Questions solved in Test mode.

In this case, there is a single straight line between the steps which does not show whether the calculations are correct. Moreover, the companions are not available.
At the end of the test, the student continues in Self-correcting mode.

They get a score for each question and the correctness of the calculations is indicated. They can modify their work to obtain a correct solution.
The student asks the companion Olivia to make a calculation step.

Olivia (16 years) solves the equation with the discriminant and provides explanations.
