A app EduCITY (https://educity.web.ua.pt/) permite explorar a cidade através de jogos educativos de localização que integram recursos multimédia em realidade aumentada (RA), com vista à mudança de atitudes dos cidadãos em prol do desenvolvimento sustentável. A ideia é promover cidades sustentáveis, criando um ambiente inteligente de aprendizagem suportado pela app EduCITY. Esta app dá acesso a jogos educativos com desafios interdisciplinares atrativos, pois integram recursos multimédia em RA, como simulações com base em dados de sensores ambientais, animações 3D, spots informativos, entre outros. Os jogos são desenvolvidos com o objetivo de serem explorados por cidadãos, de todas as idades, em passeios pela cidade, sendo cocriados pela comunidade escolar, académica e geral, através de uma plataforma web aberta (https://educity.web.ua.pt/adminjogos/index.php). Esta pedagogia inovadora usa tecnologia familiar (dispositivos móveis) para “aprender fazendo”, na qual os jogos em RA permitem consciencialização ambiental na cidade – laboratório vivo de experimentação – onde os cidadãos são “cientistas ativos” e agentes de mudanças sustentáveis, numa lógica de ciência cidadã. A app EduCITY foi desenvolvida no âmbito do projeto “EduCITY – Cidades inteligentes e sustentáveis com jogos educativos móveis em Realidade Aumentada criados por e para os Cidadãos”, com financiamento da Fundação para a Ciência e Tecnologia (ref.ª PTDC/CED-EDG/0197/2021), de 2022 a 2024. Neste projeto colaboram quatro unidades de investigação: CIDTFF, CESAM, DigiMedia e IEETA da Universidade de Aveiro.

Times tables that stick and spelling that's fun: Lalo walks your child through the primary-school curriculum (ages 6-9), five minutes at a time. Lalo, the friendly pencil, is now your child's classmate — with glasses and a magic wand — guiding them through the real school curriculum, one short 5-minute session at a time. WHAT YOUR CHILD LEARNS • Times tables — from 1 to 10, learned to mastery • Column arithmetic — addition and subtraction with carrying and borrowing, step by step • Word problems — illustrated and read aloud • Dictation and spelling — the natural voice reads, your child writes, training English spelling patterns: double letters, silent letters (kn, wr, mb), th, long vowels (ee/oo) and digraphs (ch/sh) • Numbers — bigger/smaller, even/odd, counting in steps • Telling the time — a real analog clock • Money — counting coins and giving change in US dollars • Shapes and the calendar — days and months • Fractions and measures — halves and quarters, meters, grams and liters • Coding and graphs — arrow programs that Lalo runs on the board, pictograms and bar charts to read HOW IT WORKS Lalo remembers what your child finds hard and brings it back at just the right moment (spaced repetition), so learning sticks. Mistakes are always gentle — the right answer is shown and explained, never a scolding. FOR PARENTS • A progress board shows exactly what's been mastered • Short sessions (5-10 min) — perfect after school • A PIN-protected parent area • One-time purchase — no subscriptions, no ads Grow with Lalo: complete the adventure map, level up, and dress Lalo with the prizes you earn!
