Our school is using canvas and I am a Project Lead the Way teacher who uses the pltw.instructure courses. I want my student work to integrate with district calendars and grade books. I have gone to the PLTW canvas site and exported course content, which gives me an IMSCC file. I then open my district canvas site and choose "import content into this course" and choose "Canvas Course Export Package", the indicator just spins (I left it for over an hour) and nothing seems to happen. What am I doing wrong? Does PLTW have some sort of security that prevents this from being uploaded into our district canvas account?
