Research in the field of networked learning is steadily growing due to high capabilities of computer and telecommunication systems. Tools are developed to support web-based learning and the case method is often used in different ways to teach various subjects. The goal of the CaseMaster project was to develop a Web-based platform supporting presentation of and work with cases as well as other learning scenarios over the Web and to test this way of working. CaseMaster allows creating cases (course content) as a non-linear structure like a story with one start, but with many possible different endings. A typical case often includes problems that need to be solved, connected questions, and a portfolio. First, a teacher creates a case and stores it in CaseMaster, then students work with the case and the teacher overviews the students' results, and, finally, a follow-up seminar is conducted. CaseMaster has been successfully used in the PharmaPaC project for learning pharmacology and the SwedKid project for learning more about i.e. treatment of minorities, the position of recent refugees and immigrants. The platform was also used in the course "ICT and learning" at IML. The advantages of this platform are as follows. CaseMaster advocates human interaction and gives possibility for solving problems together. CaseMaster encourages a blended learning with human meetings and discussions without attempts to replace the teacher. It does not direct the students through the content. The students will be able to create their own paths through the case and argue for their decisions. In further research, we will concentrate on evaluation of the technical functionality of CaseMaster and investigation of how much CaseMaster affects the learning process compared with traditional ways of working.
