Syllabus
Course Approval
The syllabus was approved by the Faculty Board of Technology and Science on 21 April 2008, and is valid from the Spring semester of 2008 at Karlstad University.
Course Code: MSGC12
Degree Project for Degree of Bachelor of Science in Innovation and Design Engineering, 22.5 ECTS Credits
(Examensarbete för högskoleingenjörsexamen i innovationsteknik och design, 22.5 Swedish credit points) Degree Level: Bachelor
Progression Level: C Language of Instruction Swedish
Prerequisites
112.5 ECTS credits completed on the Innovation and Design Engineering programme.
Major Field of Study Mechanical Engineering
Learning Outcomes
The aim of the course is that students acquire the ability to:
- apply the work method of an engineer and industrial designer in a product development project, or a product and service development project
- carry out an independent project and present it orally and in writing, as well as critically evaluate the work of others.
Upon completion of the course, students should be able to:
- identify, formulate, and delimit problems
- apply the knowledge and skills acquired during the course of studies on problems within the chosen field - independently plan, carry out, and document a product development project or product and service development project
- present the result orally and in writing, and adapted to a target audience
- document their own work in a report in accordance with engineering- and scientific praxis
- review and give feedback on product development projects or product and service development projects, as well as to be able to evaluate received comments on their own work.
Content and Form of Instruction
The course work is done in project form, individually or in groups, under the supervision of teachers from the university. In the case where students collaborate on a larger project, the individual contribution and area of responsibility must be clearly defiend in the initial stage of the project. The degree project provides the students with the opportunity to develop advanced knowledge in the field of innovation and design.

- opposition to the project report of another group/student
Reading List
See separate document.
Examination
Examination is based on the assessment of mandatory attendance and active participation in the intermediate and final presentations, opposition, degree project exhibition, and on the documentation of the project in the form of a written report.
Grades
One of the grades Fail (U) or Pass (G) is awarded in the examination of the course.
Quality Assurance
Follow-up relating to learning conditions and goal-fulfilment takes place both during and upon completion of the course in order to ensure continuous improvement. Course assessment is based on student views and experiences as reported in written course evaluations and/or group discussions. Students will be informed of the result of the evaluation and of the measures to be taken.
Course Certificate
A course certificate will be provided upon request.
Additional Information
