An auction of phrases, a guide to responsible vibe coding, chemistry, music and illustrated books: new in the repository

Juan José de Haro has created a participatory activity in which the teacher prepares an auction and students join with a session code to bid on phrases. It has three modes: “Conocimiento”, where students bid on the statements they consider correct and defend their decision; “Valores y prioridades”, which shares a limited budget among the ideas that matter most to the group; and “Roles y conceptos”, where a correct match earns points and a wrong one loses them. The page states that it requires no registration and that the data is ephemeral. It is available in six languages, including Spanish, Catalan, Galician and Basque. AGPL v3 licence for the code and CC BY-SA 4.0 for the content.

Juan José de Haro publishes a non-technical guide for teachers who share materials created with AI through vibe coding. According to its introduction, it grew out of materials that circulate without a licence or that send students' data to external services, and it proposes ten recommendations: correct content, data protection, accessibility, attribution, a declaration of AI use and an open licence, among others. It includes an infographic, an animation, downloadable instructions to give to the AI when creating, and a rubric (VCER) for evaluating a resource. It can be read on the web, there is a PDF version and it is available in five languages. According to its author, it is open to suggestions.

Felip Sarroca i Gil has created, with AI assistance, an interactive laboratory in Catalan for understanding the limiting reactant, the excess reactant and leftovers; according to its author, it is designed for lower and upper secondary. It has three modes: “Aprèn”, “Practica” and “Repte”. In practice mode, students see the reaction with molecular models, count how many products form and how many reactants are left over, and can ask for a hint or the solution. It offers several types of activity, three difficulty levels and a scoreboard of attempts, correct answers and streak. According to the listing, it also includes a glossary, atomic masses, progress saved in the browser and a projector mode for the interactive whiteboard. CC BY-NC-SA 4.0 licence.

FiQuiPedia presents FoQa, a Spanish-language app for practising inorganic formulation and nomenclature according to the IUPAC 2005 rules. It generates tests on binary compounds, hydroxides, peroxides, oxoacids, oxysalts, acid salts, homoatomic species and ions, and offers a converter from formula to possible names. In the panel, families and rules are chosen, such as strictness with accents, and it can be exported to PDF; according to the listing, to SCORM as well. According to its author, it was made with DeepSeek and is designed to work as a Moodle activity and report the grade to the gradebook. The newspaper has already covered its counterpart for organic formulation, FoQo. AGPL v3 and CC BY-SA 4.0 licence.
