About

i

This app is an interpreted programming language designed for educational purposes, focusing on functional programming capabilities. It allows users to test calculations, recursion, and array usage, serving as a teaching tool rather than for developing full applications.

Highlights
  • Functional programming
  • Global and local variables
  • Polish notation calculations
  • Recursive testing
  • Array usage
  • Interpreted language

LOGO was created in 1967 for educational use, is a computer programming language with functional programming capability. This version of LOGO is an interpreted language, but isn't a lite version. Functional programming with global and local variables is implemented. You can test calculations with polish notation, test recursively, and use arrays. LOGO is not a language for programming a real application, instead it is a teaching language.

Can you imagine studying polyhedrons in Geometry class using Augmented Reality? A fascinating way to discover the world of geometry! This app features 3D models with Augmented Reality for most geometric shapes. By directly interacting with the figures, your students will improve their spatial visualization. * Winner of the Academics' Choice Smart Media Award (July 2014) * Learning Best Practice Award (October 2014) * 2nd prize winner of the “La Caixa Emprendedores XXI” awards for entrepreneurs (June 2014) * Winner of the first Lanzadera business incubator program (May 2013) “The power to unfold the figures is highly didactic.” Ovi Barceló, Math teacher at Julio Verne Bilingual School, Spain. “The students’ performance improves notably almost immediately.” José Antonio Pascual Gimeno, Teaching Director and Science Teacher at Julio Verne Bilingual School, Spain. *************************************** Geometry classes like never before: * View geometric shapes from all angles and see their sides unfold into flat figures. Geometry combines conceptual content (definitions and characteristics) with procedural content (applying formulae and calculus). * Curricular content and exercises to: • Study prisms, regular polyhedra, bodies of revolution, pyramids • List their properties and the formulae that define their area and volume • Compare and identify objects in the environment with geometric shapes using Augmented Reality • Develop spatial imagination by observing 3D and flat models • Interact and discover each formula step by step • Work through exercises to practise what has been learned: guess the geometric shape, confirm characteristics and calculate area and volume * The content of this application for students from 11 years of age is completely curricular. Content is available in English and Spanish. Hundreds of schools around the world are already learning with ARLOON! * Learning Outcomes: • Cognitive Development • Critical Thinking • Engagement and Usability • Creative Development • Life Skills • Academic Relevance * Acquisition of 21st-century skills: • Scientific: geometry terms and definitions • Mathematical: geometric shapes, area and volume • Digital: studying with new technology • Learning to learn: experimenting and actively searching for answers to promote self-learning • Artistic: developing spatial imagination and the capacity for abstraction specific to geometry • Linguistic: building multilingual vocabulary (English and Spanish)
