Handouts: Reusing Diagrams and Data
Last updated
This page is named for teachers who want to put a forgetting curve or a loop diagram on a class handout or a slide. Most of what this site draws itself can be reused that way, with credit. No handout files are offered for download; what can be reused is the diagrams and data files already on the article pages.
What is under CC BY 4.0
The diagrams this site draws itself are released under the Creative Commons Attribution 4.0 license (CC BY 4.0, https://creativecommons.org/licenses/by/4.0/). That covers its forgetting and learning curves, effect-size comparisons, experiment design grids, causal loop diagrams and schedule tables. The CSV data files offered beside articles are released under the same license for this site's selection, arrangement, notes and calculated values, with the exception below.
You can copy, print, translate, adapt and share them, including commercially, as long as you give credit. Each diagram comes with a credit line you can copy. The form is:
"[diagram title]" by Feedback & Forgetting, [full URL of the article], licensed under CC BY 4.0, https://creativecommons.org/licenses/by/4.0/
Fill in the diagram's title as it appears in its credit line, and the full address of the article page where it appears. If you change the diagram, say so after the credit (for example, “relabeled” or “cropped”). Diagrams drawn from data also carry a line beginning “Data:” that names the paper and its DOI; keep that line with the diagram. A link back to the article is welcome, but it is a request, not a condition of the license.
What is not covered
Quoted values in data files. Some CSV files include figures taken from published papers. Those are marked as quoted values, and the notes file beside each CSV says which column holds them. This site's CC BY license does not cover quoted values; the terms of the original publication apply. Where a whole table comes from a paper that is itself under CC BY, or from a public-domain book, the notes file names that source and its license, and that credit should travel with the data.
Illustrations. Scene illustrations, such as a desk or a doorway, are not under CC BY. Each one carries this credit:
Illustration: Feedback & Forgetting. Generated schematic illustration — not a photograph or historical record. © Feedback & Forgetting, all rights reserved.
Third-party images. Paintings, portraits, photographs and book pages from other collections follow their own terms, which are stated in the credit beside each image. On this site they include photographs of paintings and portraits that are in the public domain in both the United States and the European Union, photographs released by museums under CC0, and collection images and photographs licensed under CC BY. Reuse them under the license shown in their credit, not under this site's terms. A CC BY image needs its own credit, as given.
Article text. The CC BY license covers the diagrams and data files above, not the articles themselves. Quote articles briefly, with a link, as you would any publication. Ideas from sources that this site only describes in its own words remain the work of their authors; cite the original paper listed in the article's sources.
Fonts
The site's typefaces are Vollkorn (headings), Sofia Sans (text) and Anonymous Pro (data and captions). All three are released under the SIL Open Font License 1.1 (https://openfontlicense.org/). They are not covered by this site's CC BY license; the font license applies to them.
Citing a page
Every article ends with a Cite this page block that gives the site name, the article title, the publication date, the date of the last substantive revision and the page address. Add the date you accessed it. No DOIs are issued for pages on this site, so please do not cite one.
Using these in a classroom
A diagram printed on a worksheet, projected on a slide or pasted into course notes needs only the credit line, placed near the diagram or in a sources list at the end. Students may redraw or annotate the diagrams for their own work under the same terms. For anything not covered here, write to contact@feedbackandforgetting.com; Raise a hand has the details, and From paper to tag explains how the underlying data were checked.
