Artiklen skitserer kort de sidste 40-50 års udvikling i naturfagene op til det nuværende fokus på undersøgelsesbaseret undervisning og udvikling af kompetencer. Den påpeger hvorledes mange traditionelle evalueringsformer, især brugt ved eksamen, ikke er i stand til at indfange de ønskede kompetencer, hvorfor de har svært ved at slå igennem i den daglige undervisning. Med udgangspunkt i en model af sammenhængene mellem formativ og summativ brug af evaluering argumenteres for nødvendigheden af større alignment mellem naturfagenes formål, pædagogik og evalueringsformer. Artiklen giver eksempler fra en række danske og internationale forskningsprojekter på udvikling og implementering af evalueringsformer, der kan indfange de nye læringsmål og som brugt formativt kan fremme deres læring. Den viser hvilke muligheder og udfordringer de rummer for lærere, og hvorledes en meget struktureret brug af evalueringer kan risikere at elevmotivationen forskydes fra en mestringsorientering hen mod en præstationsorientering. Afslutningsvis bliver der peget på forskellige måder til at håndtere modsætningerne mellem en formativ og en summativ brug af evalueringer. Dels gennem tiltag, der mindsker karakterpresset i skolen, og dels gennem udvikling af nye eksamensformer, der er i bedre overensstemmelse med en kompetenceorienteret undervisning.Nøgleord: kompetencer, evaluering, naturfag, motivation, karakterer Assessment of science competencesAbstractThe article briefly outlines the past 40-50 years of development in science education up to the current focus on inquiry-based teaching and competence development. It points out how many traditional forms of assessment, especially used for examinations, are unable to capture the desired competences, which makes them difficult to realize in daily teaching.Based on a model of the relationships between formative and summative use of assessment, it is argued for the need for greater alignment between the goals in science subjects, teaching and assessment. The article provides examples from a number of Danish and international research projects on the development and implementation of assessment methods that can capture the new learning objectives and which used formatively can promote their learning. It demonstrates what opportunities and challenges they have for teachers, and how a highly structured use of assessment may risk shifting student motivation from a mastering orientation towards a performance orientation. In conclusion, different ways are identified to deal with the contradiction between a formative and a summative use of assessment. Partly through actions that reduce the level of pressure in school for high marks, and partly through the development of new forms of assessment that are in better accordance with a competence-oriented education.Keywords: competences, assessment, science education, motivation, grading
