Att göra det okända känt : Om bedömning av kunskaper och färdigheter vid arbete i grupp
- 2010

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- An encompassing knowledge interest in this project is to study what happens in the meetingbetween group work and assessment in the pedagogical practice. There seems to be adilemma between the demand for individual assessment of student’s knowledge and abilitiesand the demand of teaching collaboration abilities through group work. A previous studyconcerning teachers’ management of group work as classroom activity (Hammar Chiriac &Forslund Frykedal, 2010) reveals that assessment is a highly relevant factor when organisinggroup work in a school setting. In addition, teachers seem to experience difficulties andacknowledge some challenges and problems about assessing students working in a group. Toour knowledge this is a rather neglected research area and very little attention has been paid toresearch on assessment of students’ performance in collaborative situations.The main purpose in this study is to explore and comprehend teachers’ conceptions ofdifficulties and worries in connection with assessing students in collaborative situations.Furthermore, we intend to scrutinize what knowledge previous research may provide as acontribution to proficiency about assessment of group work.In the empirical study we have applied a grounded theory methodology and data havebeen assembled by means of group interviews. The informants were teachers, from forms 5-9in the nine-year compulsory school in Sweden.Previous research provides little theoretical knowledge or useful tools aiding the teachersin their task but comprises more of self- and peer assessment and how group members couldcontribute to the assessment.The result shows that teachers rather use informal than formal assessment. The informalassessment is mostly done by circulating in the classroom and observing the groups.Additionally, the result discloses that the teachers have difficulties to concretize and putwords on what and how they assess. In the discussion we present some pedagogicalimplications, which may be useful in the pedagogical practice. The pedagogical implicationsare based on empirical results and previous research.

Ageing and Conservation of Silk. Evaluation of Three Support Methods Using Artificially Aged Silk
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The general aim of this thesis is to evaluate common remedial conservation support methods used in the conservation treatments of fragile silk costumes that have experienced physical damage. It is based on five papers. Paper I surveyed the methods textile conservators use to conserve historic textile costumes and their cri¬teria for a successful intervention. It also investigated artificial ageing of modern silk and wool fabrics with exposure to ultraviolet radiation to create material for laboratory-based experimental research. Furthermore, it evaluated mechanical methods to imitate natural wear in silk and wool fabrics, to simulate the handling of con¬served costumes, and to find a method to evaluate the effect of the conservation methods. The most common conservation method conservators reported using was to insert a support fabric between the outer fabric and the lining of a costume, which was then sewn on by the couching method over the outer fabric. The most important criterion for a successful conservation was aesthetical appeal. Abrasion by Nu-Martindale and tensile testing were found promising to use to achieve natural accelerated wear and to evaluate conservation methods. Paper II aimed at finding an optimal acceler¬ated ageing protocol to simulate the nature and degree of degradation found in naturally aged seventeenth century silk fabric in order to pro¬duce surrogates for experimental research. Tensile tests, Attenuated Total Reflection - Fourier Transform Infrared spectroscopy (ATR-FTIR) and Size Exclusion Chromatography (SEC), were investigated as methods for evaluating the results. Four environmental parameters were tested: relative humidity (RH), acidity (pH), ultraviolet irradiation (UV) and thermo-oxidation. For Paper III, further investigations were carried out to establish analytical markers for aged silk by additional analytical methods. The investigations were successfully complemented and verified using amino acid analysis, and measurement of pH and brightness. In both Papers II and III it was established that thermo-oxidation at 125ºC was the most suitable ageing method. In Paper IV two types of experimental damage on silk surrogates were conserved with three different methods: brick couching, laid couching, and crepeline. The conserved surrogates were further subjected to accelerated wear by using a combination of washing and tumbling, followed by tensile testing. The three interventions increased the surrogates’ strength from three to more than five times. Surrogates with a tear conserved with laid or brick couching were the least affected by wear; and, after the conservation was removed, the abraded surrogates conserved with crepeline were stronger than those conserved with the other two methods. Paper V explored the factors that determine aesthetic quality of conservation interventions. The study, based upon examinations performed by Swedish textile conservators, resulted in two factors coherence and completeness, that describe aesthetic quality.
