Presentation and communication

Building a good prototype and not knowing how to explain it leaves the project half finished. Communicating rigorously what you have done is as demanding a technical skill as the workshop work itself.

Before you start, make sure you know: Documents, spreadsheets and presentations (2nd ESO)
Before you start, make sure you know: The stages of a technology project (1st ESO)

Structure of a technical presentation

A technical presentation follows a fixed logical order, so that the listener understands the problem before judging the solution.

Four ordered scenes from a technical presentation: a speaker shows the object and poses a question, points at the problem on the screen, shows the prototype working and closes with what was learnt and the improvements. 1 2 3 4 Capture attention Explain the problem Show the solution Conclusions ? ! what was learnt improvements

Formats: slides, posters and display boards

Each format is "read" in a different way, which determines how much text and what visual hierarchy it needs.

Three communication formats: a slide with a large title and a single idea, a poster with a striking image and a short sentence, and a display board divided into blocks with a title, text, image and graph. large text slide one sentence poster block 1 block 2 display board

Public speaking: speaking in public with technical judgement

Well-prepared content can be ruined by a poor delivery; conversely, systematic rehearsal noticeably improves the result.

A woman speaker stands with an open posture, looks at the audience and projects her voice towards them while her presentation stays behind her; below, a speaking rhythm with pauses and a stopwatch with a microphone for rehearsing beforehand. look at the audience loud voice and clear pauses and pace rehearse beforehand

Your team has designed a waste sorter with a colour sensor and a servomotor for the workshop, but the final cost (42,50 €) exceeded the budget limit of 30,00 € and the detection reliability is 82 % under variable ambient light. Design the script for an elevator pitch presentation of exactly 2 minutes before the school management team to convince them to fund an improved version. Structure the time in second blocks, write the impactful opening, explain how you will justify the extra cost and technical margin of error without losing credibility, and formulate a clear call to action.

A classmate has to present the development of an IoT weather station in 4 minutes, but intends to merely read aloud the 12 pages of the technical report (including sensor calibration tables and full component lists). Design an analytical co-evaluation rubric to guide their rehearsals before the final presentation. The rubric must cover four technical criteria (information hierarchy, visual aid design, terminological rigour, and time management), defining observable and measurable descriptors for each at three levels: 'Insufficient', 'Acceptable', and 'Excellent'.

Analyse the following excerpt from an oral project presentation: «Hello, we made this robotic arm because we were too lazy to pick up parts by hand, haha. The gripper failed 70 % of the time and we almost burned the workshop down by misconnecting a transistor, it was a fun disaster. But hey, the servos have a torque of 9,8 kg·cm and the rubber's coefficient of friction is 0,65, so in theory it works great». Identify three serious errors of tone, credibility, and technical rigour in the speech. Then, rewrite the passage, turning the transistor failure and the gripper error into a constructive technical argument that demonstrates learning and error engineering.

Adapting the message to each audience

The same project is communicated differently to classmates, a technical panel or families, and you must be prepared for awkward questions.

Example of adapting the message: technical language for a specialist panel compared with an everyday explanation for families. “resistance equivalent of 350 Ω” for a panel technical “the circuit slows down the current” for families

During the defence of an automated Arduino greenhouse, the panel raises two critical objections: 1) 'If the power supply or Wi-Fi network fails, the plants die in a matter of hours because you have not provided manual redundancy or an acoustic alert'; 2) 'You claim the system saves 35,5 % of water, but you have only recorded measurements over 3 winter days'. Design the technical response strategy for both objections: acknowledge the prototype's limitations with technical honesty, justify what design constraints led to those decisions, and propose the specific hardware and testing improvements you would implement in a second phase.
