|Why shall we cary out students projects?
Germany is a high-tech country and holds leading positions in modern fields such as automation technology, micro- and nanotechnology or medical technology, etc.
At the same time, however, it is frightening to note that natural sciences, physics or even technology are considered. The basis for this position is not very popular among the younger generation. The course for this are subliminally affected by public media, or computer games as time-wasters, but also by the curricula being provided at school.
Although science lessons can come up with experiments that have already taught me as a student. Nowadays, the lower value of the natural sciences, the curriculum In other disciplines, there is little freedom for self-initiative for physical teaching. Lessons must run very often frontal.
With this article, I want to promote young people's access to science topics more attractive.
I have chosen the concept of vibration as a complex of topics, as it is used in a particularly diverse variety of ways. Manifestations occur. Here you have the possibility to have several groups of students at the same time at very different Experimental setups to edit the same content. A presentation of the results at the end can have "aha-effects" and contribute to a better understanding. In addition to the physical background, there is a second focus in the field of metrology. Here careful work and documentation can be practiced.
As a method, as mentioned above, I propose the experiment in school groups as part of a project week. For one week, 4-5 students deal with a task limited in content and time, which is a intensive examination of the matter is permitted. This promotes identification with the task and increases Motivation for the solution. Teamwork is practiced in the group, a skill that will be used everywhere in later professional life and is needed again and again.
Tasks that seem simple or even succinct at first glance often turn out to be the intensive Dealing with the topic as a difficulty that can only be solved with perseverance or creativity. This applies in particular to the metrological aspect of the experiments. Group work can be useful here. There are members who encourage others or contribute new ideas. Just as often, however, a group can also quarrel and fall out of each other. However, if the group leader (teacher) intervenes in time in this case and makes clear the problems that have arisen, the resulting experience is already positive.
As a start, I present two mechanical structures here:
