Likvärdiga betyg? En studie om tolkningen av ett kunskapskrav i Företagsekonomi på gymnasietStröm, Anna January 2017 (has links)
Syftet med denna uppsats är att illustrera och skapa en viss förståelse för hur lärare tolkar ett kunskapskrav och hur det kan skilja sig åt lärare emellan. Jag kommer också göra en tolkning av anledningarna till att det kan skilja sig åt. Jag har valt att skriva om detta ämne för det är ett svårt ämne - bedömningsarbetet är komplext för många lärare och det är också ofta debatterat och diskuterat i media och på min arbetsplats. Hur ska lärarna tolka kunskapskraven?För att illustrera detta kommer arbetet att baseras på följande frågor: 1. Hur tolkar lärarna Kunskapskraven för betyg A och E för genomförandet av projektarbete i kursen Företagsekonomi? 2. På vilka sätt skiljer sig tolkningarna och varför?Den litteratur jag valt att studera är delvis litteratur från tidigare studier vid Malmö universitet i Val avseende bedömning och betyg, och dels litteratur refererad till i uppsatser, forskningsavhandlingar och artiklar om bedömning. Dessutom har jag studerat olika regler och instruktioner från Skolverket. Som teoretisk utgångspunkt har jag valt teorier om hur man kan validera bedömningar av Anders Jönsson. Insamlingen av primära data har varit genom intervjuer. Jag har gjort fyra intervjuer med företagsekonomi lärare, och utifrån dessa försökt göra en analys av deras tolkningar av kunskapskravet.Slutsatsen är att lärare inte använder kunskapskraven bokstavligen. De väljer att fokusera mer på vissa värdeord än andra. Först och främst är det fokus på värdeord som tydligt skiljer studenter från varandra. Anledningen är sannolikt att det då är lätt att motivera betyget och för att det gör utvärderingsarbetet lättare. Hur pedagogerna lägger upp arbetet från början har också betydelse för bedömningen. Samt vilken erfarenhet pedagogerna har med sig. / The purpose of this paper is to illustrate and create a certain understanding of how teachers interpret the knowledge requirements, in swedish “kunskapskrav” and the ways in which they may differ. I will also make a careful interpretation of the reasons behind. The knowledge requirements I have studied refers to the course Business Economics at upper secondary school. I have chosen to write about this topic because it is a difficult topic - the assessment work is complex for many teachers and it is also often debated and discussed in media and at me workplace. How should teachers interpret the knowledge requirements?To illustrate this, the work will be based on the following questions: 1. How do teachers interpret the knowledge requirements for grades A and E for the implementation of project work in the course Business Economics? 2. In what ways do the interpretations differ and why?The literature I have chosen to study is partly literature from previous studies at the Malmö University in Val regarding assessment and grade, and literature referenced in essays, research dissertations and articles on assessment. In addition, I have studied various regulations and instructions from the Swedish National Agency for Education. As a theoretical point of departure, I have chosen the theories about how to validate assessments of Anders Jönsson.The collection of primary data has been through interviews. I have done four interviews with Business Economics teachers, and from these have tried to make an analysis of their interpretations of the knowledge requirement.The conclusion is that teachers do not use the knowledge requirements literally. They choose to focus more on certain value words than others in the knowledge requirements. First and foremost, focus is on the value words that clearly distinguish students from each other. The reason is probably partly because it is easy to motivate the grade then and partly that it makes the assessment work easier. How the educators put up the work from the beginning also has an impact on the assessment. As well as what experience the educators possess.

Avaliação das atipias epiteliais, graduação das displasias e presença de proteína p53 mutada no epitélio adjacente a carcinomas epidermoides de lábio / Evaluation of epithelial atypia, degree of dysplasia and presence of mutated p53 protein in the epithelium adjacent to lip squamous cell carcinomasNagata, Gabriela Sanchez 13 October 2011 (has links)
O carcinoma epidermoide de lábio (CEL), que é causado pela exposição crônica e excessiva à radiação ultravioleta do sol, é precedido por uma desordem potencialmente maligna, a queilite actínica (QA). No entanto, ainda não é possível determinar quais casos de QA evoluirão para CEL. O método mais utilizado por patologistas para prever o prognóstico de desordens potencialmente malignas é a graduação histológica das displasias epiteliais. Entretanto, o sistema é subjetivo e ineficiente quanto ao seu valor preditivo. Acredita-se que o epitélio adjacente ao CEL tenha alterações genéticas semelhantes ao corpo da neoplasia. O objetivo deste estudo foi graduar as displasias epiteliais na margem do CEL e verificar a presença de proteína p53 mutada nessas áreas. Foram utilizados 40 casos de CEL com epitélio adjacente, no qual a displasia epitelial foi classificada pelo sistema proposto pela Organização Mundial da Saúde (OMS) e pelo sistema binário. Os casos foram, ainda, submetidos a reações de imuno-histoquímica com anticorpo anti-proteína p53 mutada. Entre os 40 casos estudados, 15 apresentaram displasia epitelial discreta, 18 moderada e 7 intensa. Pelo sistema binário, 36 casos foram classificados como de baixo risco e 4 como de alto risco. A marcação imuno-histoquímica para a proteína p53 mutada foi encontrada no epitélio adjacente de 32 casos (80%) dessa amostra. Considerando-se as duas graduações estudadas, a marcação foi detectada em 11/15 casos de displasia discreta, 16/18 de moderada e 5/7 de intensa pelo sistema da OMS e em 29/36 casos de baixo risco e 3/4 casos de alto risco. Concluiu-se, assim, que o epitélio adjacente ao CEL, mesmo exibindo poucas alterações morfológicas pode ter um comprometimento genético importante em genes que comandam a estabilidade genômica. / The lip squamous cell carcinoma (LSCC), which is caused by chronic and excessive exposure to solar ultraviolet radiation, is preceded by a potentially malignant disorder, the actinic cheilitis (AC). However, it is not possible to determine which AC cases will progress to LSCC. The method used by pathologists to predict the prognosis of potentially malignant disorders is the histologic grading of epithelial dysplasia. Nevertheless, this system is subjective and inefficient as to its predictive value. It is considered that the epithelium adjacent to LSCC has genetic alterations similar to the main tumor. The aim of this study was to grade the epithelial dysplasia on the LSCC border and also to verify the presence of mutated p53 protein in these areas. Forty LSCC cases with adjacent epithelium were retrieved from our files. The epithelial dysplasia was classified by the system proposed by the World Health Organization (WHO) as well as the binary system. Three m sections were submitted to the antibody against mutated p53 protein by means of immunohistochemistry. Among the 40 cases studied, 15 were classified as mild dysplasia, 18 moderate and 7 severe. When the binary system was considered, 36 cases were classified as low risk and four as high risk. Immunostaining revealed the presence of mutated p53 protein in the adjacent epithelium of 32 cases (80%). Analyzing the two grading systems separately, the staining was detected in 11/15 cases of mild dysplasia, 16/18 of moderate and 5/7 of intense; 29/36 of low-risk cases and 3/4 cases high-risk. In conclusion, even if it shows few morphological changes, the epithelium adjacent to LSCC may have a genetic involvement in important genes that control genomic stability.

Formativ feedback i programmering med tillämpning av statisk kodanalys : Utveckling av ett verktygStålnacke, Olof January 2017 (has links)
Aim Develop an IT artifact that provides formative feedback for students based on their programming assignments. Background One of the best methods to learn programming is by practice. Providing feedback to students is an important and a valuable factor for improving learning, which plays a vital part in the student’s possibility to enhance and improve its solutions. Software development courses have several assignments and each course instructs about 100 students. To assess and provide feedback for all the students and each assignment demands considerable resources. In a survey conducted by TCO (2013) half of the respondents’ state that feedback is rarely or never given in reasonable time. Method Action Design Research (ADR) was used to intervene an organizational problem in parallel with building and evaluating an IT artifact. Conclusion The results from the study were four generated design principles and a proposed solution on how to use existing static code analysis tools for provide formative feedback to students.
