Teaching remains a craft-based occupation, but we&#x27;re haven&#x27;t yet developed tools that actually support the job of a teacher. There&#x27;s no way that Universities&#x2F;k12 school administrators will be capable of providing the level of detailed feedback necessary to teach teachers how to be effective, so we need better methods for teachers to self-assess and improve independently.<p>So much effort is being put into one-off, discrete solution to a curriculum problem (like leveled non-fiction texts, grammar instruction, etc.) - but what we really need are tools that allow me to understand what my students are capable of, support my development of curriculum materials&#x2F;activities&#x2F;assessment, and discover&#x2F;remix the multitude of learning resources that are being created in classrooms just like mine all over the country.<p>I want a VisiCalc, because I&#x27;m tired of running these numbers by hand.
