STEM Learning vs Traditional Classrooms: What Works Better?

🇨🇦 · Maker Kids · Samantha Dinelle

June 14, 2026 | MakerKids Team Both approaches have real value – but they serve different purposes. Traditional learning builds the academic foundation kids need. STEM education helps them apply it. Research consistently shows that when children have opportunities to learn through hands-on, project-based experiences alongside core academics, they develop stronger problem-solving skills, higher motivation, and better long-term retention than through traditional instruction alone. For most families, the answer isn’t choosing one over the other – it’s finding ways to combine both. How STEM and Traditional Learning Compare Why Traditional Learning Still Matters Traditional learning gives kids important academic structure. Reading comprehension, writing, math fundamentals, and classroom routines all help children build a strong educational foundation. Schools also help students learn how to manage deadlines, follow instructions, collaborate with peers, and stay organized. These skills continue to matter in every future career path, including technology-focused industries. The challenge many parents notice is that traditional classroom environments often have limited time for experimentation and creative application. Students may learn concepts in theory without always having opportunities to use them in hands-on ways. This is one reason STEM programs have become increasingly popular among families seeking additional enrichment outside of school hours. Where STEM Learning Changes the Experience STEM learning introduces a different type of engagement. Instead of only memorizing information, kids actively build, test, design, and create. A 2024 Gallup study found that 46% of Gen Z students in K-12 said their interest is driven by opportunities to engage with learning material in a hands-on way, and about 1 in 3 said they enjoy learning most when they can make real-world connections. In MakerKids programs, students use coding , robotics , Minecraft , Python, AI tools, and 3D design platforms to turn ideas into real projects. A child learning logic in math class might apply the same thinking while building a redstone system in Minecraft or programming a robot to respond to inputs. That connection helps learning feel more meaningful. Hands-on STEM activities also encourage kids to experiment without worrying about getting every answer perfect on the first try. Students naturally begin adjusting projects, troubleshooting mistakes, and improving their designs – building persistence and independent thinking in a way that feels exciting instead of stressful. Kids Learn Best When They Can Apply Concepts One major difference between STEM education and traditional approaches is how quickly kids see results from their work. When students build a game, create a robot, or design a 3D-printed project, they immediately see their ideas come to life, keeping them motivated and focused for longer. Studies comparing learning outcomes for students taught via project-based learning versus traditional instruction show that, when implemented well, PBL increases long-term content retention and helps students perform as well as or better than traditional learners on high-stakes tests (Edutopia). This is especially important for students who struggle with passive learning environments. At MakerKids, classes are intentionally designed around small group instruction and live instructor support. Students are not simply watching tutorials – they participate in collaborative projects while instructors guide them through challenges. Programs are grouped by age and experience level, helping beginners feel comfortable while giving advanced students opportunities to continue progressing into courses like Python and Unreal Engine. Preparing Kids for a Technology-Focused Future Technology is now part of nearly every industry – healthcare, business, engineering, entertainment, and design. No matter which career path students choose, they will likely work alongside technology throughout their lives. That is why many families are adding STEM programs alongside traditional school learning. Coding classes, robotics programs, Minecraft engineering activities, and AI-focused projects help students develop adaptability and digital confidence while still supporting classroom success. Ontario schools have also continued increasing the focus on coding and technology integration across multiple grade levels, making STEM skills even more relevant for today’s students. The Best Learning Approach Combines Both Traditional learning helps kids build core knowledge. STEM education helps them apply it. When students have opportunities to create, experiment, and solve challenges independently, learning becomes something they genuinely look forward to. MakerKids programs are designed to support that balance through live instructor-led coding, robotics, Minecraft, AI, and Python programs for kids across Toronto and Mississauga.

Il tuo archivio digitale sta morendo (e kage può salvarlo)

🇮🇹 · /root · Lamberto Tedaldi

Smettetela di credere che Internet sia eterno. Ogni secondo, un sito web muore, un database si corrompe o un servizio cloud decide che la tua subscription è scaduta. Stiamo vivendo in un’epoca di estrema fragilità digitale: ci affidiamo a piattaforme che non possediamo, su infrastrutture che non controlliamo, con la speranza che un domani qualcuno non decida di spegnere l’interruttore. È qui che entra in gioco kage, un progetto che mi ha fatto saltare sulla sedia. Non è il solito scraper che scarica HTML spazzatura; è uno strumento che mira a catturare l’essenza di una pagina web e renderla permanentemente tua, offline, pulita e priva di tutto quel rumore inutile (tracciatori, pubblicità invasiva, script di monitoraggio) che rende la navigazione moderna un inferno di telemetria. Il funzionamento è quasi poetico nella sua efficacia. kage non si limita a copiare il codice; simula una navigazione reale, aspetta che il contenuto si carichi e poi ‘congela’ la pagina, ricostruendola in una versione snellita e autosufficiente. Il risultato? Un archivio di pagine che funzionano anche senza connessione, dove l’unico tracciamento presente è quello della tua stessa curiosità. Cosa mi ha colpito davvero? La filosofia del ‘packing’. kage ti permette di impacchettare intere porzioni di web in formati che puoi conservare su un hard disk esterno o su un server locale. Puoi creare il tuo personale Wikipedia personale, o un archivio di documentazione tecnica che non dipenda dal fatto che l’azienda produttrice decida di spostare tutto dietro un paywall o, peggio, chiudere i battenti. Certo, non è una bacchetta magica. Non è un sostituto per una strategia di backup strutturata, e richiede comunque un minimo di competenza per gestire i flussi di lavoro. Ma l’idea di poter generare file .zim o strutture di pagine pronte per essere consultate in un bunker digitale è troppo potente per essere ignorata. In un mondo dove tutto è ‘as-a-service’ e la proprietà digitale è un miraggio, avere uno strumento che ti permette di riprendere possesso dei contenuti che ritieni preziosi è un atto di resistenza. kage non è solo un tool; è un’assicurazione sulla vita per la tua memoria digitale.

Il ritorno del passato: quando il CSS moderno incontra un motore di rendering dell’età della pietra

🇮🇹 · /root · Lamberto Tedaldi

Avete presente quella sensazione di onnipotenza che provate quando il vostro codice passa tutti i test, il linter non urla e il build è finalmente verde? Ecco, dimenticatela. Se usate i dispositivi Kobo, la realtà è molto più cruda e decisamente meno logica. Recentemente è emersa una storia che è un vero incubo per chiunque ami gli standard aperti e la pulizia del codice. Un autore ha pubblicato un nuovo eBook, tutto in regola, superando l’epubcheck con la grazia di un robot senza bug. Eppure, per i lettori Kobo, il file risultava ‘corrotto’. Il colpevole? Non è un errore nel file, ma un pezzo di tecnologia fossile: il RMSDK di Adobe. Parliamo del motore di rendering che Kobo usa ancora oggi, una roba che sembra uscita da un setup retrocomputing degli anni 2010. È il cuore di Adobe Digital Editions, quel software che tutti usiamo solo perché dobbiamo, un monumento al DRM e alla pesantezza software. Il problema è che questo motore è rimasto congelato nel tempo. Mentre noi ci divertiamo a usare CSS moderni, Flexbox, Grid e funzioni matematiche avanzate, il parser di Adobe si blocca non appena vede qualcosa che non appartiene al suo mondo preistorico. In questo caso specifico, una riga di CSS totalmente valida — una semplice funzione ‘min()’ per gestire la larghezza di un’immagine — è stata interpretata come un errore fatale. Il risultato? Nessun messaggio d’errore utile, solo un silenzioso e frustrante crash del file. Da smanettone, trovo questa cosa assolutamente inaccettabile. Siamo nel 2026! Se un software non riesce a gestire un’istruzione CSS standard senza dichiarare il fallimento totale, non è un software, è un timer a scadenza che aspetta solo di esplodere. È il classico esempio di vendor lock-in mascherato da ‘compatibilità’: Kobo si aggrappa a un motore proprietario e vecchio di un decennio, e noi siamo costretti a scrivere codice ‘povero’ e antiquato solo per non far piangere il loro parser. Per noi che amiamo smontare le cose e capire come funzionano, questo è un promemoria brutale: non potete fidarvi solo degli standard ufficiali se sotto il cofano c’è un motore che gira ancora a vapore. Se volete che le vostre creazioni (che siano eBook o script per una CNC) funzionino ovunque, dovete testarle contro il peggior scenario possibile. Dovete sottoporle al ‘tritacarne di Adobe’. In conclusione: meno hype sui nuovi standard e più attenzione alla robustezza dell’implementazione. Finché le grandi corporation continueranno a preferire il controllo del DRM alla qualità dell’esperienza utente, saremo sempre costretti a scrivere codice come se fossimo ancora nel 2013. Una vera tristezza per chi ama l’innovazione. Source: Your ePub Is fine

Smettetela di scorrere i feed: cosa state combinando davvero nel vostro garage?

C’è un momento preciso, di solito intorno alle tre del mattino, in cui la luce blu del monitor è l’unica cosa che separa il tuo progetto dal fallimento totale e il tuo cervello dal collasso nervoso. È quel momento in cui smetti di leggere le news aziendali piene di buzzword inutili e cerchi solo qualcuno che stia combattendo la tua stessa battaglia contro un bug impossibile o un motore passo-passo che non ne vuole sapere di girare. Il thread di Hacker News di giugno 2026 è appena uscito e, come ogni mese, è la nostra dose di dopamina pura. Niente comunicati stampa patinati sulla ‘rivoluzione dell’AI generativa nel cloud’ o annunci di acquisizioni che servono solo a gonfiare i titoli in borsa. Qui la domanda è nuda e cruda: «What are you working on?». Una domanda che, per noi che passiamo il tempo a modellarci pezzi in Blender o a cercare di far girare emulatori di Commodore 64 su hardware moderno, ha un peso tutto diverso. Ho scorso i commenti e, come sempre, è un mix meraviglioso di genialità e puro caos. Si parla di gente che sta scrivendo kernel personalizzati, di maker che stanno perfezionando estrusori per stampanti 3D fatti con pezzi di recupero e di dev che stanno cercando di addestrare piccoli modelli linguistici locali per gestire l’automazione della propria domotica senza mandare i dati in mano ai giganti del tech. È il rifugio sicuro contro il vendor lock-in che sta soffocando l’industria. Per noi che amiamo mettere le mani in pasta, questo thread è fondamentale. Ci ricorda che la vera tecnologia non è quella che compri su Amazon con un click, ma quella che costruisci, smonti e riprogrammi secondo le tue regole. È l’orgoglio di chi preferisce scrivere uno script in Python per automatizzare un task noioso piuttosto che pagare un abbonamento mensile a un software proprietario che non ti permette nemmeno di vedere il codice sorgente. Certo, ogni tanto spunta fuori qualche idea che sembra uscita da un episodio di Black Mirror andata male, ma è il prezzo che paghiamo per vivere sulla frontiera. Se state lavorando a qualcosa che richiede più caffè di quanto ne possiate consumare, o se il vostro progetto attuale è solo un ammasso di cavi disordinati e codice scritto con l’aria di chi ha dimenticato come si usa la documentazione, sappiate che siete nel posto giusto. Quindi, cos’è che vi tiene svegli? State perfezionando quel motore CNC o state finalmente riuscendo a far compilare quel vecchio progetto C++ senza mille errori di memoria? Fatevi sentire, prima che l’hype del prossimo grande framework ci travolga tutti. Source: Ask HN: What are you working on? (June 2026)

De regeling heeft lokaal op het kastje een aan/uit schakelaar en een regelknop, en kan extern gestuurd worden met een 0-10V signaal of een potmeter. De minimale uitgangsspanning is instelbaar (boven de helft van de voedingsspanning). We kunnen de regeling aansturen vanuit bijvoorbeeld een 'node' print of eender welke microcontroller (ESP8266/ESP32/Atmega328/RP2040, etc) door een 0-10V signaal te maken met PWM (of een DAC), of door een potmeter-signaal te maken door weerstanden te schakelen. 0-10V met PWM is waarschijnlijk het eenvoudigst. == Handleidingen en documentatie == == Handleidingen en documentatie == Regel 94: Regel 103: * [[:Bestand:Datasheet_TEE_015.pdf|Datasheet TEE 015]] de door Ruck aanbevolen 5-traps regeling, in kastje * [[:Bestand:Datasheet_TEE_015.pdf|Datasheet TEE 015]] de door Ruck aanbevolen 5-traps regeling, in kastje * [[:Bestand:Datasheet_TES_0145.pdf|Datasheet TES 0145]] de door Ruck aanbevolen 7-staps regeling, kale transformator * [[:Bestand:Datasheet_TES_0145.pdf|Datasheet TES 0145]] de door Ruck aanbevolen 7-staps regeling, kale transformator De gekozen fan-regeling is een [[https://www.tme.eu/nl/en/details/are-3.0n/ac-motor-controllers/breve-tufvassons/17000-1383/ ARE-3.0N]], originele [[:Bestand:ARE-N-instrukcja-obslugi.pdf|handleiding]] (Pools, maar leesbare diagrammen, en goed machinevertaalbaar). == Voortgang == == Voortgang == Regel 100: Regel 111: * De ventilatoren worden begin volgende maand op het dak geplaatst * De ventilatoren worden begin volgende maand op het dak geplaatst * We zijn aan het nadenken over de aansturing ervan * We zijn aan het nadenken over de aansturing ervan Juni 2026: * Er is gekozen welke ventilator-regeling we gaan gebruiken * De ventilatorregelingen zijn besteld

Fließender Strom ← Older revision Revision as of 10:27, 15 June 2026 (7 intermediate revisions by the same user not shown) Line 1: Line 1: Hier ein KI -Bild als Einstieg :</br> Für den Einstieg zwei KI generierte Atombilder zur Darstellung von elektrischen Strom :</br> [[image:Ein_einfaches_Atommodell.png| 1000px ]] </br> [[image:Elektronen_in_Isolatoren_und_Leitern.png|1000px]] </br> === Das Atom=== [[image:Ein_einfaches_Atommodell.png| 700px ]] </br> === Freie Elektronen=== Atome sind soziale Wesen und haben das Bedürfnis sich mit anderen Atomen zusammen zu tun. Das sind dann Moleküle. Dabei kann es passieren, dass Elektronen ÜBER sind, für den Zusammenschluß nicht gebraucht werden. Das ist vor allem bei Metallen der Fall. Diese Elektronen nennt man freie Elektronen, weil sie nirgends eingebunden sind. Diese freien Elektronen können als elektrischer Strom genutzt werden.</br> [[image:Elektronen_in_Isolatoren_und_Leitern.png|1000px]] </br> === Fließender Strom=== Damit die freien Elektronen zu elektrischem Strom werden, also fließen, ist eine '''elektrische Spannung''' nötig. Eine Spannung entsteht, indem sich viele Elektronen zusammenballen und so deren negative Ladung größer wird als die positive Ladung der Atomkerne in der Nähe. Bei anderen Atomen, von denen die Elektronen abgezogen wurden entsteht dann eine positive Ladung. Die Differenz der Ladungen entspricht der Spannung. Diese Verschiebung der Elektronen kann chemisch (Batterie, Akku) oder magnetisch (Generator) erzeugt werden.</br>
