A training curriculum teaching good practices in lesson design and development, and open source collaboration skills, using The Carpentries Workbench. The curriculum is designed to be taught over six half-days. The target audience is Carpentries Instructors with an idea for a new lesson they would like to create, especially if that lesson is intended for short-format training (e.g. part or all of a two-day workshop). We believe that lesson development is easier and more successful when it is a joint effort among collaborators, so the activities and examples used in this training are best suited to groups of trainees who want to collaborate on a lesson project. Efforts have been made to also cater to lesson developers working alone. After attending this training, participants will be able to: * collaboratively develop and publish lessons using The Carpentries lesson infrastructure (aka The Carpentries Workbench): lesson template, GitHub, GitHub Pages, etc. * identify and characterise the target audience for a lesson. * define SMART learning objectives. * explain the pedagogical value of authentic tasks. * create exercises for formative assessment. * explain how considerations of cognitive load can influence the pacing, length, and organisation of a lesson. * configure and maintain accessible and usable lesson repositories using best practices, readily available for collaboration. * identify and correct accessibility issues in a Carpentries lesson. * update and improve lesson material guided by feedback and reflection from teaching. * review and provide constructive feedback on lessons.
