See the Pen wave surfer – waveform by Tom (@twwoodward) on CodePen. I needed to make a quick proof of concept for the annotation of audio on the web. In this case, it’s meant to provide a visual and auditory way to play through interview segments that represent different categories of responses. I found WaveSurfer.js this morning and just a bit later I had a functional example. I find the ability to highlight track elements visually and access specific segments to be a pretty powerful combination. If we stacked several tracks vertically the visuals would quickly point out content variation in terms of timing and total composition. You could get more and more complex from there. Playing with it gave me all sorts of ideas (including possibly using it as part of of the upcoming Reclaim Your Dance Party // API + Audio = (beats, visuals, internet, participate) session at Domains 17 with Grant and Brian). It’s also looking like I’ll be able to work more with our music department to think through online course on music so possibilities like this will be very useful. This kind of thing would be pretty easy to turn into a plugin . . .

The key element is google.script.run.withSuccessHandler. I’m still not entirely sure I have this in my head deeply/correctly but this is functional and might help someone else (even if that someone is just me at a later point in time when I’ve forgotten this). This one sets some default times based on spreadsheet variables stashed elsewhere and then automates some date/time entries using the form sidebar.

This collection of dashboardsA pretty imprecise word that appears to mean quite a few different things to different people. was brought on by a tweetI will never like that word. from Dan Meyer but precipitated by the fact that I am struggling to figure out what matters in terms of a future LMS and how the data we present (or don’t present) to students and teachers impacts education as a whole.Someplace I have an interesting way that someone was visualizing learning along five thematic branches (content, critical thinking, etc.) and displaying it as a star/pentagram in order to help reflect the idea of balance. For some reason I thought it was an NSF grant but I’m not finding it currently. While weI have a frog in my pocket. often say weYep, frog is still there. want a balance between multiple choice assessment and other types of assessment, if the only data that teachers see and talk about is related to multiple choice we probably shouldn’t bother talking about other types of assessment. There’s also the idea that assessment data may just be the tip of the iceberg. I’m not sure what exactly would make a difference but there are lots of other things that ought to be looked at. In the end I see the data displayed to students and […]
