On Developing Content‐oriented Theories Taking Biological Evolution as an Example     

Björn Andersson  Anita Wallin 《International Journal of Science Education》2013,35(6):673-695

Both in Europe and the United States there is a growing interest in design research. One example is the design and validation of topic‐oriented teaching–learning sequences. This research may be said to have two objectives. One is to design and test “useful products”, such as teachers’ guides and study material for students, which may be put into practice in various ways. The second is to contribute to the development of educational science; for example, understanding conditions for learning of given topics under regular classroom conditions. This article concerns the latter objective and deals with the development of content‐oriented theories stating conditions that promote learning with long‐term understanding of given topics. We present one such theory, concerning evolution by natural selection, and describe the arguments and evidence that underlie the theory, which we regard as a well‐founded hypothesis. Some methodological problems associated with testing this type of theory are discussed, as well as the role of content‐oriented theories in strengthening science education research as an autonomous specialization within educational science.  相似文献   

BETYDELSEN AV DEN TIDSMÄSSIGA PLACERINGEN AV KUNSKAP OM RESULTATET I ANSLUTNING TILL ÖVNING MED TVÅ TYPER AV INLÄRNINGSMATERIAL

This study was designed to investigate the cross‐cultural similarity of vocational interests as measured by the Strong Interest Inventory. An Icelandic version of the SII was administered to Icelandic college students studying medicine, business, library science, geology, biology, psychology, theology, and nursing. 290 first year students were tested, and 123 students approaching final exams of whom 80 were re‐tested two years later. Reliability coefficients for the scales (occupational themes, interests, occupations and the special scales) varied from 0.79 to 0.89. On the basis of the US norms 74‐83 percent of students were correctly classified into their actual professional group. The results indicate that US norms are valid for Icelandic college students and allow for satisfying prediction of educational and vocational choice. This may indicate that the US norms of the SII could be applicable for other Nordic college students. SII scale scores for all groups indicate identical interest structure for Icelandic and US groups of the same field of study.  相似文献   

Recognising Prior Learning: Understanding the Relations Among Experience, Learning and Recognition from a Constructivist Perspective     

Andreas Fejes  Per Andersson 《Vocations and Learning》2009,2(1):37-55

This article discusses the relation between experience and learning in the context of recognition of prior learning (RPL) and from an experiential constructivist perspective. The study is based on a case of in-service training, based on RPL, in the care sector for elderly people. The data consist of interviews with actors in this process, which have been analysed with a qualitative interpretative approach. The results show how prior learning plays a central role in the training process, both on an individual and a collective level. The participants’ prior learning is taken as the starting point, particularly in learning conversations where prior learning is made visible and used, and where participants learn from each other. Further, new learning is taking place as a consequence of the recognition process, and the study particularly highlights how prior experiences could be the basis of new learning in a process of reflection and discussion.  相似文献

Improving the Bandwidth Selection in Kernel Equating     

Björn Andersson  Alina A. von Davier 《Journal of Educational Measurement》2014,51(3):223-238

We investigate the current bandwidth selection methods in kernel equating and propose a method based on Silverman's rule of thumb for selecting the bandwidth parameters. In kernel equating, the bandwidth parameters have previously been obtained by minimizing a penalty function. This minimization process has been criticized by practitioners for being too complex and that it does not offer sufficient smoothing in certain cases. In addition, the bandwidth parameters have been treated as constants in the derivation of the standard error of equating even when they were selected by considering the observed data. Here, the bandwidth selection is simplified, and modified standard errors of equating (SEEs) that reflect the bandwidth selection method are derived. The method is illustrated with real data examples and simulated data.  相似文献
