{"title":"Toward Marvels in Dynamic Geometry Teaching and Learning","authors":"I. Højsted","doi":"10.7146/AUL.413","DOIUrl":"https://doi.org/10.7146/AUL.413","url":null,"abstract":"Digital technologies are gaining an increasingly prominent role in Danish primary and lower secondary school mathematics education. The expectations are that digital technologies can support students’ development of mathematical competencies. However, studies have demonstrated that the insertion of digital technologies into school mathematics does not automatically correspond to increased student learning outcomes (OECD, 2015). In fact, digital technologies can both produce marvels and cause disasters in mathematics teaching and learning (Niss, 2016). How digital tools are implemented seems to be essential. It is, therefore, a crucial research objective to unveil how didactic sequences may be designed for the efficient implementation of digital tools. The overarching purpose of this dissertation is to identify guidelines for the design of didactic sequences that exploit potentials of dynamic geometry environments (DGEs) in relation to supporting students’ development of mathematical reasoning competency in Danish lower secondary school. The dissertation consists of five papers and this summarizing report – which, altogether, seeks to shed light on the abovementioned purpose by first examining what the potentials of DGEs in relation to reasoning competency are according to previous mathematics education research (paper I) and then examining the extent to which these potentials are currently utilized in Danish lower secondary school (paper II). Based on these initial studies, guidelines are identified for the design of didactic sequences that utilize these potentials to support students’ development of mathematical reasoning competency (papers I, III, IV and V). Methodologically, a mixed methods approach was applied with a qualitative priority. The quantitative data were collected from a web-based questionnaire that was developed and distributed to lower secondary school teachers. Anchored in design-based research methodology, the qualitative data were collected in connection with the design, testing and redesign of a didactic sequence in five different school classes. The data that were collected in the iterations of design are screencast recordings, videos, interviews, audio recordings and students’ written products. The results from the project can coarsely be summarized as follows: In the review of mathematics education research, four DGE potentials were identified in relation to mathematical reasoning competency: dragging, feedback, measuring and tracing (paper I). The results of the survey indicate that these potentials are only exploited to a limited extent in lower secondary schools (paper II). The utilization of the potentials is described in guidelines that comprise a learning trajectory in terms of 5students’ cognition, task design and the role of the teacher. The a priori guidelines that are theoretically developed initially (paper I) are subsequently refined empirically based on the data that emerged in the design-based research (paper","PeriodicalId":126978,"journal":{"name":"AU Library Scholarly Publishing Services","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116248430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Stress Estimation of Offshore Structures","authors":"Marius Tarpø","doi":"10.7146/aul.393","DOIUrl":"https://doi.org/10.7146/aul.393","url":null,"abstract":"Offshore structures are subjected to a harsh environment where the fluctuating waves continuously strain the structures and these forces cause the initiation and propagation of cracks in the structures. In other words, the structures accumulate fatigue damage, which eventually leads to structural failure. To avoid fatigue failure, the operational lifetime of a structure is limited to a design lifetime in which the structure is safe for operation. This design process is based on precautious stochastic assessments, norms, and industry standards that simplify the actual structure and environment in such a manner that it involves little risk of structural failure. \u0000As many structures in the North Sea approach the end of their design lifetime, the owners are faced with a dilemma: either abandon the field or replace the structures. Another option is the lifetime extension of the existing structures. This requires a reduction of the uncertainties in the design process - such as the stress history in fatigue-critical location. Unfortunately, these locations are often inaccessible or directly harmful to the sensors due to the hostile environment of the ocean. This thesis focuses on virtual sensing to estimate the stress/strain response of offshore structures by indirect measurements. The thesis addresses the state of the art and maps some essential issues within stress/strain estimation. In this thesis, stress/strain estimation is applied to different test specimens to address certain scientific issues. Parts of the thesis relate to the calibration of the system model for virtual sensing by operational modal analysis.","PeriodicalId":126978,"journal":{"name":"AU Library Scholarly Publishing Services","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126559174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I min undersogelse har jeg haft mulighed for at folge processerne pa taet hold blandt andet gennem feltarbejde i skolen.

{"title":"Soil-pile Interaction in Soft Soils","authors":"J. Kania","doi":"10.7146/aul.380","DOIUrl":"https://doi.org/10.7146/aul.380","url":null,"abstract":"When piles are installed through soft, subsiding soils, a drag force is developed in the piles. The consolidation induced by e.g. lowering of the groundwater table or placing the fill around the piles causes settlements and thus a relative movement between the pile and the soil. As a consequence, negative skin friction develops in the upper part of the pile, which is resisted by positive shaft resistance in the lower part of the pile and the toe resistance. This phenomenon should be considered in the design of pile foundations. Previous studies on the development of negative skin friction have mainly been performed on driven piles installed in marine clay. Driven piles installed in gyttja, a typical of Denmark, have received little attention. Consequently, there is still insufficient documentation for the effect of bitumen coating in reducing the shear force between the pile and the soil in such ground conditions. Additionally, all the test piles in the reported studies were instrumented with spot sensors giving information only at discrete points. Therefore, the full distribution of strain along the piles was not possible to obtain. The present thesis investigates the soil-pile interaction in soft, subsiding soils using a distributed fibre optic sensing system, which provided a high spatial resolution. The development of and the controlling factors behind negative skin friction along uncoated and bitumen coated piles were of special focus. These objectives were obtained through a program of full-scale field tests, supplemented by laboratory soil-pile interface shear tests. \u0000This PhD study has shown that the development and magnitude of negative skin friction was a function of effective stress and settlement. The soil-pile interface type had an impact on the magnitude of the shear stress in both full-scale and laboratory tests. The bitumen coating significantly reduced negative skin friction and its efficiency is related to the shearing rate. Finally, driven piles can be successfully instrumented with distributed fibre optic sensors providing continuous distribution of strain along piles.","PeriodicalId":126978,"journal":{"name":"AU Library Scholarly Publishing Services","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134171019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
