We just launched badges for Khan Academy

Yesterday we added a brand new badging incentive system to the Khan Academy. It's really simple for now, round 1, blah blah all that jazz. We're dealing with all types of internal debates about proper behavior to encourage and how users will respond. We've seen students in schools get extremely excited about very, very simple game mechanics attached to their practice problems/homework/etc, and building the roots of a deeper badging system seemed like an important next step to help us guide users through desired paths in the system. You can check out all of our badges here…

What it does

In the maker’s words, at launch

Yesterday we added a brand new badging incentive system to the Khan Academy. It's really simple for now, round 1, blah blah all that jazz. We're dealing with all types of internal debates about proper behavior to encourage and how users will respond. We've seen students in schools get extremely excited about very, very simple game mechanics attached to their practice problems/homework/etc, and building the roots of a deeper badging system seemed like an important next step to help us guide users through desired paths in the system. You can check out all of our badges here http://www.khanacademy.org/badges/view (and I blogged just a bit more information at http://bjk5.com/post/2426884194/khan-academy-now-has-badges). Would love to get some feedback.

    made a html5 game, polished it many many times2011 · hotbazooka.com · ▲211

    hi all, I've always wanted to make my own game, but couldn't afford a thousand-dollar adobe (flash+photoshop) license. I'm not a talented programmer, have no degree in CS. But I understand some elements of design. So I got me a copy of ImpactJS, and after about 5 months of steep learning curve (at least for me), I managed to come up with a game. I also integrated it with a highscore and badge system, similar to what you get at Kongregate. You need to login with Google/OpenID to earn badges/scores. link is: http://www.hotbazooka.com/privatejoe hope to hear some feedback/questions from you guys!

    Meatshields – An in-browser turn-based strategy game2017 · ▲113

    A few months ago (82 days to be exact!) I posted a link on HN to my game, Meatshields. A bunch of you commented and played my game and gave me some wonderful feedback. Over the last few months I've been playing with many of you and implementing the best of everybody's suggestions. So, thank you, HN for all your help! I feel this is an extreme overhaul I couldn't have done without your input. Since then, I have: Dramatically improved our hosting platform (So it HOPEFULLY won't go down this time (oops.)), Added two new units, Rebalanced all existing units, Added many more maps, Improved the…

    The Class Placements Game2023 · game.classplacer.com · ▲7

    I’m (re)building a tool to help elementary schools place students into classes (original app still uses jQuery… porting to React). Placing students into classes is kind of like a puzzle where the first kids are easy, but when you get close to the end, you realize your earlier placements need to be moved around endlessly. That’s why I wrote an algorithm to help. Anyway, teachers tell me it’s kind of fun, so I made a game out of it! This game simplifies the process a lot in the name of getting something that’s solvable by hand and playable on a smartphone. Hope you enjoy.

    Our startup Construct 2, how far we've come and lessons learnt so far2012 · ▲12

    We did a "Show HN post" 6 months back of our startup and we're very excited to show everyone how far we've come as well as the lessons we've learnt so far! It's been a roller-coaster so far and we think there's lot more of the same to come! We did apply for Ycombinator funding but got turned down :( But may re-apply soon :) For those that don't know, our startup is called Scirra and we make Construct 2 which is an HTML5 game engine (http://www.scirra.com). Our engine allows anyone to make HTML5 games without knowing any programming. It's only me and my brother working on this and we're based…

    RewardHackBench: Using sandboxes to stop agents from cheatingJun 2026 · github.com · ▲9

    hey all, happy to share research i've been working on for islo.dev in recent months. ever since the cheating agents (https://debugml.github.io/cheating-agents/) paper came out, revealing reward hacking was 4x more prevalent than previously estimated, i've been looking into how we can deal with the issue the common approach (taken by the tbench team) is post hoc trajectory analysis. i've been interested in the idea of reframing the problem as an endpoint security problem and tackling it via sandbox i hope you find it interesting, and thanks to the islo.dev team for…

  • Eigendrum - Draw any shape and hear what it sounds like as a drum▲243

    Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
