The aims of this study were to understand current status of professional development schools in the state of Maryland, USA. The definition, theoretical framework and theories of PDS were discussed firstly. Then, the researcher went on analyzing the PDSs of Towson university and collaborative elementary schools in Maryland, in order to find out the collaborative model and their implementation. There were five purposes in this study. The first purpose was to understand the definition of PDS. Secondly, the theoretical framework was discussed. Thirdly, the theories of PDS were explained and explored. The forth purpose was to analyze the implementation in the PDSs of Towson University and the collaborative elementary schools in Maryland. Finally, to synthesize the results of this study, the researcher suggests some strategies in the establishment of partnership between teacher education universities and elementary schools. For these purposes, the author made use of methods of document analysis and case study to discuss teacher education endeavors in Towson University, teacher¡¦s professional development and organizational change in schools withibn collaborative elementary schools, in order to understand the current status of the PDSs in Towson University and the collaborative elementary schools. According to the results, the following conclusions have been concluded: 1. Action research and inquiry into practicum should be highlighted in the PDSs, in order to improve the achievement of students from both sides. 2. Due to different context in the PDSs, diversified measures sould be provided. 3. Integration of teacher education, teacher¡¦s professional development, research and inquiry did improve the learning achievement of students. 4. Teachers in PDSs can promote themselves in professional development. 5. Teachers in PDSs need to be evaluated regularly in order to maintain their professional quality. 6. Whole member of university, school, family or community are supposed to participate in the improvement of students¡¦ achievement. Based upon the above conclusions, several suggestions have been raised by the researcher to play a solid basis for the country¡¦s teacher education and to upgrade the quality of future teachers.

En svensk skolkommuns ambitioner har varit att klättra på skolrankingen. Ett sätt att göra detta är att utforma ett kommunalt matematikprov för årskurs 5 i syfte att upptäcka kunskapsluckor i god tid innan det nationella provet i årskurs 6. Syftet med studien är att undersöka hur detta prov påverkar matematiklärarnas arbete. Detta har undersökts genom kvalitativa intervjuer av de berörda matematiklärarna. Svaren har analyserats utifrån den teoretiska utgångspunkten sociomatematiska normer. Vi har också analyserat det matematiska innehållet i ett arbetsmaterial som kommunen har uppmanat lärarna till att använda som förberedande material. Resultatet pekar på att matematiklärares arbete påverkas i hög grad av att huvudmannen anordnar ett centralstyrt matematikprov. Detta gäller det matematiska innehållet i deras undervisning och därmed de sociomatematiska normer som råder i klassrummen. Vår slutsats är att kommunens intention att påverka lärarnas arbete infrias, men hur det på längre sikt påverkar elevers kunskapsutveckling återstår att undersöka. / A Swedish school municipality's ambitions has been to climb the school rankings. One way of doing this is to design a test for fifth grade pupils in order to discover gaps in students mathematical understandning well ahead of the national tests in the sixth grade. The purpose of this study is to investigate how this test affects the work of mathematics teachers. This has been investigated through qualitative interviews of the involved mathematics teachers. The data have been analyzed based on the theoretical starting point of socio-mathematical norms. We have also analyzed the mathematical content that the municipality has recommended the teachers to use as preparatory material. The result indicates that the work of mathematics teachers is very much influenced by the fact that the municipality organizes a central-controlled mathematics test. This applies to the mathematical content of their teaching and the socio-mathematical norms prevailing in the classrooms. Our conclusion is that the municipality can influence and alter the teachers' work both inside and outside the math class.
