Start from the lesson, not the resource
The most common mistake when using open materials is browsing first and deciding later. A better order is to write down what the lesson needs to achieve, then look for something that fits. A short note is enough: the topic, the age or level of the group, the time available, and what students should be able to do at the end. Teachers who work from clear learning objectives usually find it much easier to tell whether a resource is a fit or merely interesting.
It also helps to list the constraints. Do students have devices in class? Is there reliable internet? Do some learners need larger text, captions or a translation? These answers narrow the search before you spend time reading anything in depth.
Choosing a candidate
When you find a possible resource, run through a short screen before investing in it.
- License: is it stated clearly on the resource? Does it permit changes? A NoDerivatives license, for example, means you can use it as it is but not edit it.
- Source: who made it, and when was it last updated?
- Level and fit: does the vocabulary, pacing and cultural context match your group?
- Format: can you actually edit it? A word-processor file, a web page or a slide deck is easy to change; a locked PDF or an embedded video is much harder.
Shortlist two or three options rather than taking the first. Comparing them often reveals which one needs the least rework.
Planning the adaptation
Adapting does not have to mean rewriting. Think in layers, from lightest to heaviest touch:
- Use as is. Assign the reading or show the diagram unchanged.
- Select. Take only the sections that serve the lesson and leave the rest.
- Localize. Swap examples, names, units or places for ones your students recognize.
- Reshape. Change the order, add worked examples, break a long text into steps, or write new questions.
- Combine. Merge parts of several resources into one handout or sequence.
Start with the lightest change that works. Heavy rework consumes planning time, and it is easy to underestimate how long it takes. Evidence on whether adapted materials outperform off-the-shelf ones is mixed, so the aim is a good fit for your learners, not change for its own sake.
Check any added material as well. If you write new explanations, run them past a colleague or compare them against a trusted reference, because errors are easy to introduce when editing quickly. Adding a worked example or two can be useful for newcomers to a topic, but too much extra detail can overload them, so keep additions focused.
Fitting it into the lesson plan
Once the content is settled, place it in the structure of the lesson. Decide where the resource appears (introduction, main activity or follow-up), how long students will spend on it, and what they will do with it. A reading with no task attached tends to be skimmed; a reading with two clear questions gives students a reason to engage.
If your course uses a flipped classroom or blended model, check whether the resource works for independent study at home as well as in the room. Materials that depend on your explanation in person may need extra signposting to stand alone.
Consider assessment too. If you want to test understanding of the open material, write your own questions rather than assuming a set that came with the resource suits your outcomes.
Keeping track of changes
A simple change log saves trouble later, particularly if you plan to share your version or if your school asks where material came from. Record, for each resource:
- the title, creator and link to the original
- the license and version, if stated
- the date you accessed it
- a short description of what you changed
- the license you will apply to your adapted version, if it is shared
A single spreadsheet or document is enough. If you edit files, keep the original unchanged in a separate folder and give your edited versions clear, consistent file names so you can tell which is which. Where a license has a ShareAlike condition, your adapted version generally needs to carry the same license, so note that at the time.
For credit, many licenses expect the title, creator, source and license to be named. A line at the foot of the handout is typically enough, but check the license wording for what it asks.
Practical cautions
Third-party content inside an open resource, such as a photograph or chart with its own different license, may not be covered by the main license. Look for notes on images and embedded media. Where licensing is unclear, leave the item out or replace it.
Be realistic about educator workload. Searching, screening and adapting takes real time, and the saving is not always obvious in the first term. The effort often pays back when you reuse a resource across classes or years.
Also gather feedback. After the lesson, note what worked and what did not: where students were confused, which questions were too easy, which sections ran long. Add these notes to your log. Next time you will know what to fix first, and that record is often more valuable than the original edit.
A short example workflow
Suppose a teacher needs a one-hour lesson on a topic in the school curriculum. In outline: write the objectives, shortlist three open lesson resources, pick the one with a flexible file format and a license that allows changes, cut it to the two relevant sections, replace two examples with local ones, add three questions, record the changes in the log, and credit the original on the handout. After the lesson, add a line to the log about how it went. None of this requires specialist software, only a little discipline about recording what you did.
