This study investigates how well prepared student teachers are to implement species identification in school. Data were collected with the help of a questionnaire and a PowerPoint presentation in which local plant and animal species were presented. Participants (n = 357) correctly identified, on average, 23% of the plants and 44% of the animals. They identified plants mainly by flower characteristics and leaves, and animals mainly by shape and colour. Family and school were key sources of participants’ knowledge of species. The self-estimated competence of participants to identify species was positively correlated with their taxonomic knowledge and the amount of time they had spent on species identification during their own schooldays. The number of correctly identified plant and animal species increased with interest in identifying species and participation in species identification courses. Participants considered learner-centred education and experience-based learning, and the use of living organisms to be most important when identifying species in school. (DIPF/Orig.

Vom Hochschulseminar zum interdisziplinären E-Lehrverbund

Die Nutzung von Formen des E-Learning an Hochschulen muss im Zusammenhang mit den traditionellen Lehrformen bewertet werden. Wir schlagen vor, dass der Gebrauch von digitalen Medien und Kommunikationswerkzeugen im akademischen Unterrichtsbereich nicht unabhängig von der komplexen Lernstruktur des klassischen Seminars betrachtet wird. Zuerst verlangt dies eine Analyse des gemeinschaftlichen Aufbauprozesses von Wissen. Nur vor diesem Hintergrund kann dann das didaktische Potential der entsprechenden medientechnischen Gestaltungen bewertet werden. Mit Erfahrungen aus dem bundesweiten Lehrverbund RION sollen Möglichkeiten, Probleme und Vorzüge eines didaktischen Designs, das auf Zusammenarbeit fokussiert, veranschaulicht werden

Do student teachers’ wildlife value orientations impact how they judge management actions of carnivore species from different habitat status groups?

Lethal management of carnivore species in Germany differs according to the species habitat status (i.e., for new arrivals, long-established, or re-colonizing species). Management actions are not always accepted by the public. Since prospective teachers are future multipliers of public acceptance of lethal management, and teaching is influenced by ones’ value orientations, we investigated student teachers’ (N = 95) decisions on lethal management of carnivore species of different habitat status groups in relation to their wildlife value orientations (WVOs). Our results show that student teachers’ WVOs are more strongly associated with certain management actions for new arrivals and re-colonizing species than for long-established species. In those cases, their WVOs are more likely to affect teaching of decision-making in the context of management actions. Thus, teacher education should support student teachers in reflecting their value orientations for teaching local biodiversity protection

Two Peculiarities of Economic Education

In order to model economic competences and to draw the didactic-methodological consequences it is necessary to take into account specific conditions of the conceptual development concerning economic issues and the respective learning paths. In this respect economic education has to deal with two fundamental peculiarities. First, the concept of the market as system unintendedly coordinating a multitude of actions is not transparent in the individual action. Thus, the learning paths to this concept of market cannot just build on the concept of the market as the concrete place of economic interactions. Second, the market’s systemic coordination of feedback processes, particularly the negative ones, is rather unintuitive. Intuition prefers unidirectional linear causal relations. These two interrelated peculiarities are present in the cognitive development of economic concepts. Competence requirements have to be defined respectively and methodological choices in teaching systemic ‘phenomena’ have to reflect this constraint Um ökonomische Kompetenzmodelle zu entwickeln und daraus didaktisch-methodische Konsequenzen zu ziehen, ist es notwendig bestimmte Bedingungen der konzeptuellen Entwicklung ökonomischer Zusammenhänge sowie diesbezüglich relevante Lernwege zu berücksichtigen. In dieser Hinsicht muss sich ökonomische Bildung mit zwei Besonderheiten auseinandersetzen: Erstens, das Konzept des Marktes als System nicht-intendierter Koordination einer Vielzahl von Handlungen ist in der einzelnen Handlung nicht einsichtig. Daher kann der dieses Konzept betreffende Lernweg und entsprechende Lehrmethoden nicht einfach am Marktkonzept als konkreter Ort konkreter wirtschaftlicher Interaktionen ansetzen. Zweitens, die systemische Koordinationsleistung des Marktes in Bezug auf Rückkoppelungsprozesse, insbesondere negative Rückkoppelungen, ist relativ unanschaulich. Unsere Anschauung präferiert unidirektionale lineare kausale Verknüpfungen. Die beiden Besonderheiten stehen somit in engem Bezug zur kognitiven Entwicklung ökonomischer Konzepte. Kompetenzanforderungen und die Wahl von Lehr/Lernmethoden in Hinsicht auf systemische ‚Phänomene‘ müssen daher diese Bedingungen bedenken

covRNA: discovering covariate associations in large-scale gene expression data

OBJECTIVE: The biological interpretation of gene expression measurements is a challenging task. While ordination methods are routinely used to identify clusters of samples or co-expressed genes, these methods do not take sample or gene annotations into account. We aim to provide a tool that allows users of all backgrounds to assess and visualize the intrinsic correlation structure of complex annotated gene expression data and discover the covariates that jointly affect expression patterns. RESULTS: The Bioconductor package covRNA provides a convenient and fast interface for testing and visualizing complex relationships between sample and gene covariates mediated by gene expression data in an entirely unsupervised setting. The relationships between sample and gene covariates are tested by statistical permutation tests and visualized by ordination. The methods are inspired by the fourthcorner and RLQ analyses used in ecological research for the analysis of species abundance data, that we modified to make them suitable for the distributional characteristics of both, RNA-Seq read counts and microarray intensities, and to provide a high-performance parallelized implementation for the analysis of large-scale gene expression data on multi-core computational systems. CovRNA provides additional modules for unsupervised gene filtering and plotting functions to ensure a smooth and coherent analysis workflow
