Using an algorithmic language in French and a simple, user-friendly graphical interface, this software makes it easy to design and test algorithms that may be encountered in secondary school mathematics education.

The source code for the algorithms is built step by step using ready-to-use commands (read, display, assign, if...then statements, loops for...from...to and while...): this allows beginners to focus primarily on algorithmic logic rather than learning complex syntax. Once the algorithm has been developed, it can easily be executed to verify its validity.

In order to be able to approach various mathematical situations, Algobox includes an editor in the form of a hierarchical tree, where most commands are entered by pressing the buttons on the graphical interface corresponding to the basic algorithmic structures. However, raw code editing is also possible in a classic text editor (included with the program), without using the ready-to-use commands.

Jupyter is a web application used for programming in more than 40 programming languages, including Python, Julia, Ruby, R, and Scala[2]. It is a community project whose goal is to develop free software, open formats, and services for interactive computing. Jupyter allows you to create notebooks, i.e., programs containing both text, simple or enriched typographically and semantically thanks to the simplified Markdown markup language, and code, source lines, and execution results. These notebooks are used in particular in data science to explore and analyze data.

This is the tool offered on this key for Python programming.

OCaml, formerly known asObjective Caml, is the most advanced implementation of the Caml programming language, a language from the ML family of languages, and is an open source project led and maintained primarily by Inria.

Caml is a functional language enhanced with features that enable imperative programming. OCaml extends the language's capabilities by enabling object-oriented and modular programming.

It integrates these different concepts into a type system inherited from ML, characterized by static, strong, and inferred typing.

The type system allows for easy manipulation of complex data structures: algebraic types, i.e., hierarchical and potentially recursive types (lists, trees, etc.), can be easily represented and manipulated using pattern matching.

Strong typing, as well as the absence of explicit memory manipulation (presence of a garbage collector), make OCaml a very safe language.

It is a powerful language for teaching and is often used for learning programming.

The editor used on the key by clicking on the menu icon is EMACS

LibreOffice Calc is the spreadsheet software in the open source LibreOffice office suite. It offers an interface similar to that of Microsoft Excel, allowing you to easily create and edit spreadsheets using an interactive editor. s and perform operations automatically.

The software is organized in cells that form a double-entry table. LibreOffice Calc has a variety of features for managing columns, rows, backgrounds, borders, etc. You can create matrices, graphs, pivot tables, and even macros in the software.

With LibreOffice Calc, you can use formulas (equations that use numbers, text, and variables to obtain a result) to simplify and automate calculations.

Intuitive and with a simple toolbar interface, Logisim is used to design and simulate processors for educational purposes. This software allows you to design circuits and observe their simulation at each stage of construction. It also offers the possibility of building larger circuits from small sub-circuits.

Logisim is a tool written in Java.

Scratch is a graphical programming language for educational purposes, which can be manipulated and executed by the software of the same name.

Scratch allows the program code to be modified during execution. Scratch is multimedia-oriented with the aim of teaching children or beginners about the world of computing, and is based on the manipulation of objects. Scratch works using a visual editor, with all code written directly in the user's native language (more than 70 languages are available) in the form of colored blocks (e.g., controls in yellow, variables in orange, movements in blue). It allows basic programming concepts such as loops, conditions, tests, and variable assignments to be implemented visually.

The Scratch cat, named Scratch-Cat, is the site's mascot and the default sprite found in every project when it is created. It also has a distinctive meow that is included among the sounds of the default sprite in newly created projects.

Software recognized in the scientific community: Regressi is a tool for acquiring, presenting, processing, and analyzing experimental data. It is the software of choice in the scientific community. It is also a benchmark in high schools, universities, and businesses.

Regressi is compatible with equipment such as spectrophotometers, oscilloscopes, electrodes, scales, etc. It is indispensable for scientific experiments in the laboratory. Although data is acquired via recorded images or videos, measuring devices can be connected directly to the computer.

AviMeca is a small, unique piece of software that can be extremely useful. Math and physics teachers are particularly fond of it.

Avidemux is video software that allows you to cut, perform simple editing, apply filters and subtitles, and re-encode videos.

Audacity is free, open-source audio editing software. It allows you to record, manipulate, and mix audio files in various formats. With Audacity, you can also apply sound effects such as noise removal, equalization, and volume adjustment. It is a very useful tool for musicians, podcasters, or anyone working with audio files. The software is available on Windows, Mac, and Linux.

 

Audacity allows you to edit (copy, paste, cut) sounds on multiple tracks. Users can also enhance and retouch recordings with around 40 available effects (speed and pitch modification, audio normalization, amplification, noise reduction, etc.).

Arduino is the brand name of an open-source prototyping platform that allows users to create interactive electronic objects from hardware-free electronic boards containing a microcontroller.

The schematics for these circuit boards are published under a free license. However, certain components, such as the microcontroller, are not.

The microcontroller can be programmed to analyze and produce electrical signals in order to perform a wide variety of tasks such as home automation (controlling domestic appliances such as lighting and heating), robot control, embedded computing, etc.

It is a platform based on a simple input/output interface.
