VideoClipQuests (VCQs) are a teaching-learning approach focussed on the learner{\textquoteright}s self-activity while information is collected by searching the Internet, similar to the well- established concept of WebQuests. VCQs can be one element to sensibly integrate the possi- bilities and advantages of the virtual world into teaching. Some of the advantages of VCQs are that they allow the teachers great latitude, they can be created very easily, they are com- patible with a multitude of learning platforms, and they can be used both in e-Learning and traditional lectures. Moreover, they appear to inherently motivate the learners and thus be- come highly accepted. In this chapter we present the concept of a VCQ as well as first evalu- ation results of their influence in learning.

Der {\"U}bergang von einem ordinalen Zahlkonzept zu einem strukturierten Zahlbegriff f{\"a}llt manchen Kindern schwer. Wir stellen vor, wie diesen Kindern mit Hilfe des Computers die {\guillemotright}Kraft der F{\"u}nf{\guillemotleft} n{\"a}hergebracht werden kann. Dabei stellt sich als entscheidender Vorteil heraus, dass die Kinder F{\"u}nferp{\"a}ckchen virtueller Pl{\"a}ttchen mit einem {\guillemotright}Griff{\guillemotleft} nehmen k{\"o}nnen, ohne die Pl{\"a}ttchen einzeln abz{\"a}hlen zu m{\"u}ssen, diese aber dennoch auch wieder einzeln gegriffen werden k{\"o}nnen.

VideoClipQuests {\textendash} in short: VCQs {\textendash} are a teaching-learning-approach focussed on the learner{\textquoteright}s self-activity while information is collected by searching the Internet, similar to the well-established concept of WebQuests. VCQs can be one element to sensibly integrate the possibilities and advantages of the virtual world into teaching. Some of the advantages of VCQs are that they allow the teacher great latitude, they can be created very easily, they are compatible with a multitude of learning platforms, and they can be used both in e-learning and traditional lectures. Moreover, they appear to inherently motivate the learners and thus become highly accepted. In this paper we present the concept of a VCQ as well as first evaluation results of their influence to learning.

Abstract: Which route should the garbage collectors{\textquoteright} truck take? Just a simple question, but also the starting point of an exciting mathematics class. The only "hardware" you need is a city map, given on a sheet of paper or on the computer screen. Then lively discussions will take place in the classroom on how to find an optimal routing for the truck. The aim of this activity is to develop an algorithm that constructs Eulerian tours in graphs and to learn about graphs and their properties. This teaching sequence, and those stemming from discrete mathematics, in particular combinatorial optimization, are ideal for training problem solving skills and modeling {\textendash} general competencies that, influenced by the German National Standards, are finding their way into curricula. In this article, we investigate how computers can help in providing individual teaching tools for students. Within the Visage project we focus on electronic activities that can enhance explorations with graphs and guide students even if the teacher is not available {\textendash} without taking away freedom and creativity. The software package is embedded into a standard DGS, and it offers many pre-built and teacher-customizable tools in the area of graph algorithms. Until now, there are no complete didactical concepts for teaching graph algorithms, in particular using new media. We see a huge potential in our methods, and the topic is highly requested on part of the teachers, as it introduces a modern and highly relevant part of mathematics into the curriculum.
