Teilnehmerbericht der online CAMMPweek 2020

Wie kann man Windräder aufstellen, sodass man die maximale Energie erhält?

Die CAMMP week fand aufgrund des Corona-Virus online statt und nicht wie immer, in einer Jugendherberge, wo sich die Schüler für eine Woche trafen. Die Woche ging schon an einem Sonntagabend los, an dem sich alle in einem virtuellen Konferenzraum versammelten. Beim Warten ploppten hier und da Gesichter von anderen Teilnehmern auf, die jedoch schnell ihre Videofunktion wieder deaktivierten. Dann ging es schon das Willkommenstreffen mit einer kleinen Einführung über Mathematische Modellierung und der Vorstellung der Probleme los.

Um sich danach besser kennenzulernen, haben sich die Betreuer etwas Neues überlegt, da alles digital erfolgt: An einem Whiteboard, wozu alle Bearbeitungsrechte besaßen, bekam jeder seinen eigenen Kreis. Nun hatte man circa zehn Minuten Zeit in den Kreis Sachen zu zeichnen, die man über sich offenbaren wollte. Nach den zehn Minuten durfte dann jeder sein Kunstwerk vorstellen, und, falls man eine Kamera hatte, auch sein Gesicht zeigen. Um ehrlich zu sein, war ich da doch schon aufgeregt als sich die Betreuer meinem Kreis immer mehr näherten, da man sich nicht sehr oft vor einem Haufen schwarzer, emotionsloser Kästen (mit kleinen Namen in der Ecke) vorstellt. Nach ein paar weiteren Spielchen war es doch schon recht spät geworden und damit endete das erste Meeting.

Am nächsten Tag kam man wieder gestärkt, unter anderem weil es immer erst um 9 losging, in den Meetingraum und nach einer kurzen Begrüßung wurde auch schon die Verteilung der Projekte bekannt gegeben. In einem Viererteam wurde uns die Aufgabe der Optimierung von Windparks gegeben. Daneben gab es andere spannende Probleme über optimale Solarzellenausrichtungen und dem Beladungen von Großfrachtfahrzeugen. Nach diesem Meeting traf sich jeder im Meeting der eigenen Gruppe inklusive Betreuer. Als erstes mussten wir erst einmal die Aufgaben verstehen und Unklarheiten beseitigen. Dann ging es schon ans Modellieren. 

Das Problem bei Windparks ist nämlich, dass sich die Windräder durch ihren Windschatten beeinflussen, sodass hintere Windräder manchmal viel weniger Wind abbekommen und somit weniger Leistung liefern. Also gilt es erstmal herauszufinden, wie so ein Windschatten überhaupt aussieht. Um 12:30 gab es dann die Mittagspause, die mit dem Pausenexpress endete. Dort konnten sich Freiwillige vom langen Sitzen erholen und konnten sich mit Yoga und ähnlichem entspannen. Nach einer kurzen Ansage der Betreuer, begaben sich die Gruppen wieder in ihre eigenen Meetings und es wurde fleißig am geteilten Whiteboard Ideen ausgetauscht und weitergearbeitet.

So ging die Woche weiter, was jedoch keinesfalls langweilig war, da man ständig mit diskutieren, zuhören, Code schreiben, sich fragen warum der Code nicht funktioniert und nachdenkend in die Luft starren beschäftigt war. Wenn es einmal gar nicht weiterging, waren die Betreuer sehr hilfreich und konnten einen auch in die Richtung lenken. Dazwischen gab es auch interessante Vorträge über das Studieren am KIT oder RWTH Aachen und auch wieder virtuelle Spielrunden, um den Kopf wieder freizubekommen.

Am Donnerstag stieg die Spannung ein wenig, weil man sich nun unmittelbar auf die Vorträge vorbereiten musste, aber die Gruppe noch ganz knapp vor dem Ziel ist. Jedoch verliefen die Probevorträge recht gut, sodass man sich eigentlich nicht zu sorgen brauchte.

Am Freitag, dem letzten Tag, trafen sich alle Teilnehmer, Betreuer, etc. nochmal zusammen im großen Meetingraum, bevor es dann ins Zoom-Meeting ging, wo jede Gruppe ihre Präsentation hielt. Neben den Schülern und Betreuern sind dann doch noch viele Eltern, Lehrer und Verwandte gekommen, um den virtuellen Präsentationen zu lauschen. Nach jeder Präsentation durften sich die Problemsteller auch zu Wort melden, die die Gruppen auch vielfach lobten, aber auch Verbesserungstipps gaben.

Im Großen und Ganzen hat die CAMMP week sehr viel Spaß, trotz der weiten Entfernungen zwischen den Teilnehmern, gemacht und ich kann es auf jeden Fall weiterempfehlen.

Bericht der online CAMMPweek 2020

Vom 27.09. bis zum 02.10.2020 fand die diesjährige CAMMP week, erstmals im online Format, statt. Während dieser Woche haben 25 Schüler/innen ab Klasse 10 aus Baden-Württemberg und der Städteregion Aachen in kleinen Teams an verschiedenen Fragestellungen geforscht. Bei den Fragestellungen handelte es sich um offene Problemstellungen, welche von Firmen und Instituten gestellt wurden. Bei ihrer Arbeit wurden die Schülerteams von wissenschaftlichen Mitarbeiterinnen und Mitarbeitern von KIT und RWTH Aachen unterstützt.

Mit verschiedenen digitalen Kommunikations-Tools (einer Plattform mit Chat- und Videokonferenz-Funktion), einem digitalen Whiteboard und einer online Programmierumgebung arbeiteten die Schüler/innen intensiv an den Problemen und präsentierten ihre super Ergebnisse am Ende der Woche vor den Firmenverteter/innen und weiteren interessierten Gästen.   

Wir freuen uns, dass die CAMMP week auch im virtuellen Format eine spannende und gewinnbringende Erfahrung war, aber drücken dennoch die Daumen, dass wir uns im nächsten Jahr wieder persönlich treffen können.

Wir bedanken uns an dieser Stelle nochmal ganz herzlich bei allen Betreuerinnen und Betreuern, Problemstellerinnen und Problemstellerinnen, Förderern und weiteren Unterstützern, die diese CAMMP week möglich gemacht haben. Ein besonders großer Dank gilt jedoch den Schüler/innen, die so motiviert an den Fragestellungen gearbeitet haben! 

Zitate von teilnehmenden Schüler*innen:
„Ich habe gelernt, im Team zu arbeiten, ein Problem selbstständig zu lösen und Ideen der Gruppe vorzustellen.“
„Ich habe einen Einblick in mathematische Forschung bekommen, was mir bei meiner Berufswahl helfen wird.“
„Die Woche hat Spaß gemacht und meinen Horizont erweitert. Danke!“

Registration for the CAMMP week is open

The CAMMP week this year takes place online from 27.09. - 02.10.2020. The registration is open until 30 July 2020.

Implementation of online CAMMP days

As a joint project between the CAMMP locations in Aachen at the RWTH and the KIT in Karlsruhe the CAMMP day workshops are now also available as Online CAMMP days.
These can be held on site at school or in self-study by the students. We also offer online CAMMP days for classes or courses via a conference tool.

All you need is a web browser. An installation of programs is not necessary.

Further information and a contact form for providing access data can be found on the cross-location website of the CAMMP project.

CAMMP in Mexico

From October 17th to 26th Martin Bracke (TU Kaiserslautern), Maren Hattebuhr (KIT), Sarah Schönbrodt (KIT), Janna Tinnes (RWTH Aachen), and Kirsten Wohak (KIT) visited the Universidad Autónoma de Baja California (UABC) in Tijuana as representatives of the projects CAMMP (Computational And Mathematical Modeling Program) and KOMMS (Competence Center for Mathematical Modeling in MINT Projects in Schools). There, Mexican students gained insights into problem solving with the help of mathematical modeling in the form of several modeling days and a modeling week.

First of all, an introduction to the idea and goals of CAMMP and KOMMS was given to the local scientific assistants. With the beginning of the new week we started a series of successful one-day workshops and a modeling week with their support.

The approx. 160 students were consistently motivated, enthusiastic and interested. They also learned a lot of interesting facts from these new experiences and were able to improve their modeling skills. We, too, gained many instructive and exciting experiences while working with students from another culture.

A big thank you goes to the organizer Luis Ramon Siero Gonzalez (UABC) and Professor Martin Frank (SCC). It was a successful and very eventful time for us.

 

Participating students of CAMMP week 2019 powered by Bürgerstiftung selected

The application and selection phase is now complete. The applicants have been informed of the selection. This year, students from the following schools are participating (in alphabetical order):

  • Albert-Schweizer-Schule
  • Goethe-Gymnasium Gaggenau
  • HLA Rastatt
  • Max-Planck-Gymnasium Karlsruhe
  • Robert-Bosch-Gymnasium Langenau
  • Tulla-Gymnasium Rastatt

In the next few weeks, participants will receive further information on the procedure through mail.

Our young people are also successfully researching in the Baden-Württemberg state competition!

After the successful start at Jugend forscht in the regional competition Mannheim, Boyu and Christian astonished the jury from 27-29.03.2019 with their application-oriented and practical topic on casting-compatible design. They received two special prizes for their creative ideas. The state competition of Baden-Württemberg took place in the Schwabenlandhalle in Fellbach with a further 64 projects. The young researchers presented their projects and inspired the jury, an interested public and each other with their outstanding results. The focus was less on the idea of competition and more on marvelling at the research work. Unfortunately, it was not enough for our team of pupils to win the state prize in the field of mathematics/computer science. "We wouldn't have had a chance against the first place anyway. They really do great mathematics," Boyu and Christian praised the winning team. Behind the crass mathematics are algorithms for determining the minimum number of moves in the game "The Towers of Hanoi" under a fixed number of squares and discs, as well as approaches to prove the algorithms. From now on, our CAMMP researchers are directing their curiosity towards their studies, which they plan to start in October.

Our youth researches successfully!

On February 26 and 27, two teams of students from the project Simulierte Welten at Jugend forscht answered questions from the jury and an interested public and presented the results of their intensive research work. The student teams had got to know the research topics at the CAMMP week in Voeren, Belgium, and returned to the schools enthusiastically after a week of hard work. "One has the feeling to do something meaningful with one's knowledge", Nils Rauscher described his commitment, which he continued together with Moritz Müller, as well as Boyu Wu and Christian Beitzinger in the scholarship of the project Simulierte Welten supervised by Maren Hattebuhr. Their creative ideas were praised and rewarded at Jugend forscht. In total, almost 100 students competed in seven different categories.

Design suitable for casting

For a long time now, a wide variety of products have been manufactured by casting. Liquid metal is poured into a mould and cooled down. Particularly in the case of moulds with large differences in wall thickness, cavities can arise which have a negative effect on the stability of the cast. In order to be able to detect such weak points automatically, Boyu Wu and Christian Beitzinger developed a process that shows the designer where the mould needs to be reworked before casting. For testing, the students received data of casting moulds from the company Magma in Aachen as well as a reference time, which Magma's currently used software needs for evaluation. The two students submitted their work in the category mathematics/computer science. Boyu and Christian were awarded first prize, donated by the Fraunhofer-Gesellschaft, and are now allowed to participate in the Baden-Württemberg Youth Research State Competition. "Their idea is mathematically very clever. The project is practical and saves a lot of work when experimenting," said Professor Seiler, a member of the jury, praising the two students. We congratulate them on their victory and wish them every success in the next selection round.

Optimal loading strategy

Internet shopping is widespread. In Germany alone, 68% of private customers shop online. But also companies that are active in the wholesale and sanitary trade order products from wholesalers, who in turn commission forwarding agents to deliver the goods. To make delivery as efficient as possible, transport routes are optimised and individual customer orders are combined into tours. But do the goods even fit on a truck? Here, "fit" means not only that the products must not exceed the maximum permissible volume and weight, but also that they can be unloaded in the specified delivery sequence without having to move other goods to be delivered later. This problem is made more difficult by the fact that the products may not be stacked on top of each other at will. Until now, the trucks have simply been loaded in the opposite delivery sequence. It is not unusual to find that several vehicles are needed for the tours. Moritz Müller and Nils Rauscher came to the conclusion that this can be optimised. They wrote a program into which the data of the tours can be read and within a few seconds it is output whether the tour is possible and how the truck should be loaded in the best possible way. The efficiency was tested on the basis of real data provided by the company INFORM from Aachen. The two students convinced the jury with their creative approach and implementation. "This is a very important project, which can go straight into application," amazed a guest who got to know the two young researchers on the public day. For their work, Moritz and Nils were honoured with the 2nd prize in the field of the working world and were thus the best team in their field. The prize was donated by the Federal Ministry of Labour and Social Affairs. We congratulate them warmly!

Report by Nils Rauscher about his participation in the CAMMP week 2018

From 24-28.06.2018 Nils Rauscher (student at Tulla Gymnasium Rastatt) participated in the CAMMP week in Voeren, Belgium. Read here about his experiences.

"The CAMMP week: A week where interested students come together to solve a task set by companies using mathematical modeling. It has been taking place for some years now for young people from Aachen and the surrounding area from the 10th grade up to their Abitur. This year it took place for the first time for students from Karlsruhe, so that we, ten boys and girls from this region, were able to set off with our supervisors Maren Hattenbuhr and Kirsten Wohak for Voeren in Belgium on June 24. After a drive of about five hours we reached our destination, where gradually all 42 students, about 14 teachers and 7 supervisors gathered. The week started with a game to get to know each other. Teams of six had to build something in 15 minutes out of limited materials that would keep two eggs in the air as long as possible and allow them to land as safely as possible. During this game not only the ice between us students broke, but unfortunately also some egg shells. Afterwards Prof. Dr. Martin Frank explained to us what mathematical modeling actually is, using GPS. After this lecture we were even more excited about what would be our task for the week.

The next morning the seven tasks were presented by the respective supervisors. Then the group work began. The goal of each task was to write a code in MATLAB to solve the respective problem. The groups proceeded at different speeds. Setbacks were common and therefore the level of frustration was sometimes relatively high. But what united all groups was the ambition to solve the task at hand. This was reflected in the fact that work was often carried out beyond the time set in the plan and the sentence "How - there is already food?" was not uncommon. On Wednesday, a lecture on studying at the RWTH Aachen University was held to show the students the wide range of offers at this university. Afterwards there was a soccer tournament, where the level was partly higher than the one we had to watch afterwards in the game Germany vs. South Korea. The sobering course of the match made some of them prefer to continue working on their projects, because in the evening they had to visit some of the students who wanted to follow the progress of their task. With new impulses and encouragement from this meeting we continued the next day with the fight against our tasks. Slowly nervousness started to appear, because until the afternoon we had to prepare our presentations, which were to be held the next day in front of parents, commissioning parties and classmates, for a rehearsal talk and to finish the report about our task. However, we were sometimes far from finished with our codes. This deadline was only partially met by many groups, so that the report, the codes and the lecture were sometimes worked on until late in the morning.

The next morning was unfortunately already the last one in Voeren. The bus to Aachen started at 9:30 am and after a 45-minute drive, during which we excitedly went through our own parts of the presentation, we arrived in Aachen at the Sparkassen-Forum. At 11:15 a.m. the presentations of the individual groups began, where the solutions were presented and the task formers thanked the students for the hard work on their problem. After four hours of interesting lectures, the rich buffet was plundered and the farewell was on the agenda. It was very difficult for us, because the atmosphere was great and many new friendships were made. But we were also happy to make up for the missing sleep on the drive home.

The conclusion of this week was extremely positive. During the week, each group managed to find a solution to a problem that often seemed unsolvable in the beginning by minimizing unnecessary waste of time, for example by sleeping.

Many thanks to the responsible organizers at the RWTH Aachen and KIT for making this great week possible! We are looking forward to participate again next year".

Teachers' experience report on CAMMP day Google

Experiences with "CAMMP day" on the topic: "How does Google actually work and what does it have to do with math" of the Tulla-Gymnasium in Rastatt in June 2018.

At the end of the school year 2017/18, after the written Abitur exams, the Tulla-Gymnasium Rastatt participated with the entire class level in the "CAMMP day" of KIT on the topic: "How does Google actually work and what does it have to do with math?
In the Google module the students had the opportunity to discover the secret of the most used search engine worldwide. The module was prepared in a very appealing and comprehensible way so that all students - no matter whether they were rather less interested in mathematics or more interested in mathematics - were able to explore the topic step by step. In teams of 2-3 students, simple MATLAB programs (starting from any page) were used to search the Internet and create a ranking of the pages found. Through didactically very well instructed experiments with small networks, the students were then able to explore the underlying mathematical theory step by step. Due to the problem-oriented approach, the students got to know new mathematical concepts in a playful way.
The relevance of the application was certainly also important. In the past, at "Leistungskurs" times, matrix multiplication was a topic in the curriculum. This module would have been a great offer in this context as well. But today it seems even more important to show the students a real application reference - especially if it has something to do with their everyday life.
An important aspect is certainly not least that the networking of different contents from the fields of stochastics, linear algebra and analysis was the focus of this workshop.
Therefore: We will definitely come again next year!
