1. The influence of national curricula and national assessments on teachers’ beliefs about the goals of school mathematics
Sammanfattning : What students should learn in school and therefore also what teachers should teach is an important issue worldwide. Mathematics teaching (and teaching in other subjects) is often regulated by some form of governing text in a written curriculum communcating a set of standards. LÄS MER
2. Control Strategy for Energy Efficient Fluid Power Actuators : Utilizing Individual Metering
Sammanfattning : This thesis presents a solution enabling lower losses in hydraulic actuator systems. A mobile fluid power system often contains several different actuators supplied with a single load sensing pump. One of the main advantages is the need of only one system pump. This makes the fluid power system compact and cost-effective. LÄS MER
3. Mobile Fluid Power Systems Design : with a Focus on Energy Efficiency
Sammanfattning : This work deals with innovative energy efficient fluid power systems for mobile applications. The subjects taken up concern to what extent and how energy losses can be reduced in mobile working hydraulics systems. Various measures are available for increasing energy efficiency in these kinds of systems. LÄS MER
4. Opening the black box of mathematics teachers’ professional growth : a study of the process of teacher learning
Sammanfattning : There is a lot of research done on professional development programs for teachers, especially with a focus on different characteristics of the program and whether it makes teachers change their teaching practice to such an extent that it enhances student achievement. However, there is not much research done on the learning process. LÄS MER
5. Lösa problem : om elevers förutsättningar att lösa problem och hur lärare kan stödja processen
Sammanfattning : Generellt sett domineras matematikundervisning av utantillinlärning och arbete med rutinuppgifter. Om undervisning till störst del görs på detta sätt kommer elever ha svårt att att utveckla andra viktiga förmågor i matematik såsom problemlösning, resonemang och begreppsförståelse. LÄS MER
