What retention means
Retention describes whether a learner who starts something is still taking part at a later point. In a university, it usually means a student who enrolled in one term is enrolled again in the next, or the next year. In a short online course, it means someone who signed up is still watching, reading or submitting work a few weeks later. The two settings are quite different, and the numbers should not be compared as if they measured the same thing.
Retention is also not the same as success. A student can stay enrolled and struggle, and a student can leave for a good reason, such as a job offer or a change of plan. That is why careful discussions separate people who were pushed out from people who chose to move on.
The main reasons students leave
Studies and institutional surveys of why students leave tend to point to a handful of recurring themes. No single cause explains most departures, and they often combine.
- Money. Tuition, living costs, lost income and the price of required materials can all make continuing hard. For many students the issue is not one large bill but several small ones arriving together.
- Time. Work, caring responsibilities and travel compete with study. Learners who fit education around a full week are often the first to fall behind when something unexpected happens.
- Preparation. A course that assumes background knowledge the learner lacks can feel impossible within the first few weeks, even when the learner is capable.
- Belonging and connection. Students who feel invisible, isolated or out of place are often less likely to persist. This matters especially online, where nobody notices an empty seat.
- Health and wellbeing. Stress, illness and student mental health can interrupt study for reasons unrelated to ability.
- Fit and motivation. Some learners discover that the subject or the format is not what they expected.
Outcomes vary a great deal between people, institutions and countries, so any list like this is a guide to what to look for, not a prediction for an individual.
Where open materials might matter
Open educational resources are teaching and learning materials that are free to access and, depending on the license, free to reuse and adapt. Their most direct connection to retention is cost. When a required text is free from the first day, one financial obstacle is removed, and textbook costs are a plausible reason some students delay buying books or drop a course. How far this matters depends on the setting, and the financial barriers involved are wider than books alone.
A second possible link is access on day one. If everyone in a class can open the reading in the first week, nobody falls behind simply because they were waiting for a book to arrive or a payment to clear. Whether free course materials actually change study habits is a separate question.
A third possibility is flexibility. Openly licensed material can be downloaded, translated, read on a phone or adapted for an accessible format, which may help learners with limited connectivity or particular needs. This connects to the wider digital divide: free content helps little if a learner has no reliable device or connection.
What open materials cannot do
It is easy to overstate this. Free materials do nothing about a lack of time, a family emergency, an unsupportive environment or weak preparation. A course built on poor teaching is not rescued by a zero price. Some students also leave for reasons that are entirely sensible and would not be called a failure by anyone.
Open materials may also vary in quality, fit and support, just as commercial ones do. Free is a pricing fact, not a pedagogical one. What probably matters most is how the materials are used: whether the course is well designed, whether learners get feedback, and whether anyone notices when a student goes quiet.
Supports that sit alongside materials
Because the reasons for leaving are so varied, retention tends to be discussed in terms of a package of supports rather than a single fix. Commonly mentioned ones include:
- Clear expectations and workload estimates at the start.
- Early check-ins that identify students who have stopped engaging.
- Academic help for those who arrive under-prepared.
- Community, whether peer groups, mentors or discussion spaces, which supports sustaining student motivation.
- Flexible deadlines and pacing for working adults.
- Advice on money and practical problems.
Open materials can be one item in that package. They are unlikely to be a substitute for the rest.
Reading the evidence with care
Claims that open resources raise retention should be read cautiously. Students who choose or are assigned a course using free materials may differ from other students in ways that also affect persistence. A simple before-and-after comparison can be misleading when a new policy arrives at the same time as other changes. Many reports measure course completion or final grades rather than long-term enrollment, and results from one institution or one subject may not carry over to another.
For these reasons, honest summaries tend to say that the evidence is mixed or modest, and that results depend on context. A reader who meets a confident claim of a large effect should ask how the groups were compared, how many students were involved and whether anything else changed at the same time. The usual weaknesses are worth knowing before reading any retention evidence.
A realistic takeaway
Students stay when the costs are manageable, the workload fits their life, the content is within reach, and someone or something connects them to the course. Open education can plausibly ease the first and the third, and perhaps help with the second and fourth. It is best thought of as removing one obstacle rather than guaranteeing that students will stay.
For anyone planning a course or a policy, the practical step is to find out why students in that particular setting leave, rather than assuming the answer, and then to choose supports that match. For learners, it is worth knowing that dropping out is common, that the reasons are rarely a personal failing, and that asking for help early is usually easier than recovering after months of silence.
