On the day of a competition, a science club may give the impression that everything is at stake in a spectacular prototype. The real test comes several months later: do the students know how to explain what they measured, can the supervisor repeat the activity with another class, and does the equipment still work? In 2026, UNESCO recognized African clubs, including two from Cameroon, but a prize does not address these issues of continuity. The ADEA journal on STEM education in nine African countries emphasizes teacher training, resources, and evaluation, not just events.
A measurable goal before the purchase
A club can start with a question of proximity: comparing the temperature of two surfaces in the yard, tracking rainfall over a season, or testing the quality of a small sensor. The objective should state what a student will be able to do at the end: distinguish a measurement from an estimate, keep an observation log, calculate an average, and discuss an error. A shopping list does not replace this objective. Even if the budget allows only a thermometer and graph paper, one can still teach the importance of repeating measurements and being cautious about a single number.
The first activity should be reproducible with locally available supplies. Only then should a more complex project be undertaken. Each team records the assembly, cost, replaceable parts, and problems encountered. A demonstration video can show a device that works once; the notebook allows another team to understand why it worked. This is the educational capital that the club retains when its members leave school.
Support, safety and inclusion
The responsible adult does not need to know all the answers in advance, but he or she must set the framework. For an electrical experiment, specify the permitted voltage, insulate the cables, and prohibit any improvised connections to the network. For a water collection experiment, avoid dangerous places, provide hand washing, and obtain permission to leave the classroom. Safety rules are part of the scientific method: they ensure that an experiment can be repeated without endangering the students.
Participation is not just measured by the number of girls enrolled. Who operates the instruments? Who presents the results? Who programs, draws, writes, or chooses the topic? A rotating roles register can reveal and correct asymmetries. If only one student constantly controls the computer, the club may be a demonstrator rather than a team. Transportation constraints, schedules, and access to toilets also play a role in maintaining youth participation.
Evaluate without turning the club into an exam
Before the project, ask the participants to explain how they would check a measurement. Ask a comparable question again after a few sessions to see if the reasoning has changed. Don't attribute all progress to the club without a comparison group; the course, the surroundings, and the time also have an effect. However, modest gains can be documented: a better labeled graph, an uncertainty mentioned, a hypothesis rejected after testing. Photographing the notebook, with consent, is often better than a triumphant poster.
A quarterly report can publish four elements: cost per activity, regular presence, replicable experience, and open questions. This allows the club to seek specific material support rather than vague sponsorship. The ADEA journal notes that impact assessments are still rare; a well-described local protocol addresses this gap without claiming to solve STEM education for an entire country.
Plan the succession before the last session
Many clubs rely on one enthusiastic person. Their departure can be enough to stop all activities if they hold the only passwords, contacts and instructions. A simple solution is to write, after each project, a transferable sheet: the question posed, the duration, the equipment, possible hazards, the steps, the expected results and possible variations. Two students of different levels can repeat the experiment from this sheet. If they fail, the documentation is not clear enough. This transfer test is as formative as the original project.
The inventory of equipment should distinguish between what is loaned, donated, or purchased by the school. Fragile items should be stored with their cables and a checking procedure. Even a modest replacement budget avoids the situation where a broken wire brings the measurement to a halt. Digital files need backups and understandable names. Student photographs, on the other hand, should not be automatically published with project data: their preservation and use require appropriate permissions.
Engage families and professionals without taking over the project
An intervention by an engineer, agronomist, or technician can show what the learned methods are for. It is worthwhile to prepare it with questions from the students. An impressive but incomprehensible demonstration may produce enthusiasm for a day without lasting learning. One can ask the guest to comment on the errors of a prototype and the controls he would apply to the work. This conversation gives a more accurate picture of science than a discourse on individual genius.
Families can also contribute without funding: allowing a local observation, telling a water story, or proposing a measurement problem. However, it is important to avoid a school project collecting personal or health data without a clear framework. The club is neither a public service nor a certified laboratory. Its strength lies in learning to ask a careful question, gather limited evidence, and honestly explain what the evidence does not demonstrate.
A schedule of twelve sessions rather than a vague promise
A quarter can be structured around three cycles. In the first four sessions, students formulate a local question, learn about the instrument, and learn to record repeated observations. The next four sessions are devoted to comparing, correcting, and possibly modifying the protocol. The last four sessions are devoted to analysis, reporting, and sharing the data. This schedule is not a universal rule; it shows that a club needs time to discover its mistakes. A competition in the middle should not interrupt the entire progression.
Each cycle can keep a modest product: a measurement sheet, a graph with units, and then a report explaining what didn't work. The facilitator avoids giving the "right" interpretation right away. He asks what results would change the team's mind. When materials are scarce, groups can rotate between the roles of measurement, analysis, and documentation. This sharing is more equitable than one group always doing and another always watching.
Measure the club's impact with caution
The attendance of a club often depends on initial motivation; its members may already have a greater interest in science than their peers. Comparing their grades to those of another group does not automatically prove a causal effect. A more careful follow-up can collect initial skills, observed changes, and teacher testimony, while also indicating other possible influences. The simplest indicator is not necessarily the grade: knowing how to verify a source, recognize an error, or explain a failed experiment are essential learning experiences.
Success should also be measured from the perspective of the less visible students. If the seniors still present and the new students still set up the tables, the club risks reproducing a hierarchy. Anonymous interviews and the rotation of tasks can reveal this problem. Training the next generation means allowing a new class to take over a protocol, criticize it, and come up with a better one.
What this changes – or does not change – for Central Africa
A regional network of clubs could exchange protocols adapted to the seasons, languages, and resources of the schools, rather than copies of the same competition. An experience on rain in Douala does not require the same schedule as an experience in a drier region. Data can be compared provided that the instruments, units, and measurement conditions are specified. Before recounting the success of a Cameroonian club, RECA should visit a session, talk to several students, and obtain the necessary image permissions. The award is the beginning of an investigation; sustainability is demonstrated over time.
