When sharing an in-class exercise, an out-of-class exercise, or an exam problem use your post to provide sufficient background information about the course (General Chemistry, Quantitative Analysis, Instrumental Analysis) and the principles the exercise illustrates. Including an answer key or other notes for instructors also is helpful.
Choose a file format that is accessible to most users for your files — .pdf, .xls, .xlsx, .doc, docx, and .csv are good choices. Be sure to provide sufficient information so that those using your data know how it is organized. A typical entry might look like this for a Word spreadsheet:
File: Name (with the name linked to the URL where the file is stored; more below)
There are three options for linking to your documents. One option is to insert the file using the “Add Media” icon, which uploads the file to the server and creates a URL link to the file. A second option is to store the file on your web site and link to it using the “Insert/Edit Link” icon to create a URL link to the file. Finally, a third option is to store the file in a publicly accessible folder in a cloud app such as Dropbox and link to it using the “Insert/Edit Link” icon to create a URL link to the file.
