Experiential learning is a process of learning through direct experience, where individuals engage in activities, reflect on their actions, and apply what they’ve learned to new situations. Rather than solely reading or listening, learners actively participate, often experimenting, making mistakes, and adapting.

In learning and problem-solving, a "trial" is a single attempt or effort to reach a goal or find a solution. Each trial involves testing an idea or making a change, then observing the result. If the trial doesn’t succeed, adjustments are made based on what was learned, and a new trial begins. This process, called "trial and error," continues until the desired outcome is achieved. Trials are key in learning because they allow us to explore, adapt, and improve with each attempt, reducing mistakes and moving closer to success over time.

In learning and problem-solving, an "error" is the difference between what we aimed to achieve and the actual result. It shows how far we are from the desired outcome and helps us understand what needs adjusting. Errors aren’t failures; they’re valuable feedback, guiding us to make improvements in each new attempt. By identifying and reducing errors through practice and adjustments, we gradually get closer to the goal. In this way, errors are essential to learning, as they highlight what doesn’t work and point us toward what might.

Essentially, there are two type of errors:

the "bad" errors (often happen only once)

the "innocent" (unpleasant but useful minor misstep) 

Turn to Your neighbour, discuss the question "what was the worst error (e.g. the biggest fuckup) You ever did/caused in Your life". After 5 minutes, each couple will be asked to present at least one such error to the plenum.

"Errare humanum est, sed in errare perseverare diabolicum" (Seneca, 62 A.D.)

To err is human, to stay in error diabolical.

In learning, skill-building, and habit formation, repetition is the process of repeatedly practicing or performing a task. This continuous repetition reinforces memory, builds familiarity, and over time, transforms skills into habits or reflexes, making actions more automatic and effortless. Through repetition, connections in the brain are strengthened, allowing tasks to be completed with less conscious effort.

Homo ludens, or "the playing human," is a concept introduced by cultural theorist Johan Huizinga, highlighting play as a fundamental aspect of human culture. This view proposes that play is not only a leisure activity but a primary driver of creativity, learning, and social development. In play, humans explore rules, roles, and freedom, creating a space for innovation, ritual, and expression. Huizinga argues that play shapes not just individual behavior but entire cultures, influencing arts, law, and societal norms. Homo ludens thus redefines humanity as inherently playful, suggesting that play is as crucial to society as work or reason.
