Qualitätssicherung im österreichischen Hochschulsystem

Die ?sterreichischen Universit?ten und Fachhochschulen sind gesetzlich dazu aufgefordert, interne Qualit?tssicherungsprozesse und -systeme zu entwickeln. Der Grundsatz der Erstverantwortlichkeit der Hochschulen für die Sicherung von Qualit?t in Lehre, Forschung und Organisation tr?gt der Hochschulautonomie Rechnung, und er kommt durch die im Zuge des Bologna-Prozesses vereinbarten Europ?ischen Standards der Qualit?tssicherung zum Ausdruck. Als Qualit?tssicherungsagentur für den gesamten Hochschulbereich in ?sterreich bietet die AQA Universit?ten und Fachhochschulen externe Begleitung, vermittelt unabh?ngige Expertise und führt Evaluierungen durch. Die AQA hat ihre Leistungen und Verfahren auf Grundlage europ?ischer Standards der externen Qualit?tssicherung für Universit?ten und Fachhochschulen entwickelt. Die Verfahren der AQA stellen die hochschulinterne Qualit?tskultur in den Mittelpunkt: Basierend auf den Erfahrungen mit externen Evaluierungsverfahren und des Hochschulvergleichen, welche die AQA seit 2004 durchgeführt hat, implementiert die Agentur nun ein Verfahren, welches das hochschulinterne Qualit?tsmanagement st?rken soll und den Hochschulen l?ngerfristig eine Zertifizierung ihres Qualit?tsmanagements bietet. Die AQA stellt hierfür die Expertise internationaler Expertinnen und Experten zu Themen des Hochschulmanagements bereit und nutzt Kooperationen mit anderen Qualit?tssicherungsagenturen. Auf l?ngere Sicht k?nnte ein prozessorientiertes "Quality Audit"-Verfahren eine Referenz der externen Qualit?tssicherung für den gesamten ?sterreichischen Hochschulbereich darstellen.     

How Much Time Do You Spend Online? Understanding and Improving the Accuracy of Self-Reported Measures of Internet Use

Given the importance of survey measures of online media use for communication research, it is crucial to assess and improve their quality, in particular because the increasingly fragmented and ubiquitous usage of internet complicates the accuracy of self-reported measures. This study contributes to the discussion regarding the accuracy of self-reported internet use by presenting relevant factors potentially affecting biases of self-reports and testing survey design strategies to improve accuracy. Combining automatic tracking data and survey data from the same participants (N = 690) confirmed low levels of accuracy and tendencies of over-reporting. The analysis revealed biases due to a range of factors associated with the intensity of (actual) internet usage, propensity to multitask, day of reference, and the usage of mobile devices. An anchoring technique could not be proved to reduce inaccuracies of reporting behavior. Several recommendations for research practice follow from these findings.     

Akademisches versus schulbezogenes Fachwissen – ein differenzierteres Modell des fachspezifischen Professionswissens von angehenden Mathematiklehrkräften der Sekundarstufe

Educational research has introduced different models for the professional knowledge of (pre-service) teachers. Existing studies show major differences regarding the construct of content knowledge, which is often conceptualized based on school subject knowledge and varies with respect to academic content knowledge. The latter indicates that the question of what content knowledge teachers need has yet to be resolved. This question is particularly relevant from the perspective of teacher education at universities, since pre-service teachers for secondary schools are usually taught academic content knowledge. In this article we suggest a model of the discipline-specific teacher knowledge that includes pedagogical content knowledge (PCK) alongside two constructs of content knowledge: academic content knowledge (CK) and school-related content knowledge (SRCK). Findings from two studies for the subject area mathematics confirm that the components are empirically separable and that the three-dimensional model is superior to the two-dimensional model (CK, PCK). Moreover, the new construct SRCK holds potential for the investigation of the knowledge of pre-service teachers.

Challenges of engineering education and curriculum development in the context of the Bologna process

The work of Activity 1 of the Thematic Network E4 “Employability through Innovative Curricula” on curriculum development issues has been guided by the intention to contribute to the establishment of a European Higher Education Area (EHEA) by addressing crucial aspects of harmonisation, compatibility and comparability. In due course the activities aspired to contribute to the enhancement of engineering education by encouraging diversity and innovative solutions to deal with a range of changing demands. Creative competitiveness and the strive for specific profiles of engineering qualifications on a high level of quality must be accompanied by the attempt to make diversity and quality transparent and comparable based on common terms. The article describes briefly various demands and discusses the challenges of the Bologna Process on the development of engineering education in Europe and how some of the meanwhile 45 signatory countries deal with it. Based on the published Outcomes of Activity 1 and referring to examples of good practice it focuses on components of innovative curricula which should guide curriculum development to satisfy various needs including those of the Bologna Process.     

Preschool teachers' and students' attitudes towards playful preschool activities: a cross-cultural comparison between Germany and the Netherlands

This study compares the attitudes of preschool teachers and students between the Netherlands and Germany towards typical play activities in preschool. The data were responses to short video clips of preschool children's play and elicited the respondents’ attitudes through questionnaires. The data were analysed by classifying the written responses into four categories. The frequencies of the categories were tested with MANOVA with regard to expert–novice position and country. Differences between professionals and novices were found, and for professionals only, the four categories were interrelated, showing a stronger holistic view of early childhood activities. Differences were also found between the countries, and two of the categories seemed especially sensitive to cultural differences. We discuss how reflection on activities can add to a higher degree of professionalism, as well as a more profound understanding of ways to improve preschool teacher training.     

Customer centred community application design: Introduction of the means‐end chain framework for product design of community applications

Abstract

This paper discusses the application of the means‐end chain (MEC) framework for investigating customers cognitive”; structure regarding community applications. It is argued that the understanding of customers cognition is crucial for the development of sustainable communities. MEC analysis is seen as a mean to support the community design tasks, especially concept development. The MEC analysis within concept development helps to improve the success rate of a newly designed community by the early integration of customer needs and benefits. Based on theoretical considerations about the MEC framework and its limitations a case study regarding an information community is illustrated. Data was collected conducting individual laddering interviews online at a major information portal in Germany. Dividing answers into attributes, consequences, and values and using content analysis hierarchical value maps (HVM) for both, messaging applications and information ‐portals, were constructed. To support concept development of a new information community, as a distribution platform for content, the findings of both HVMs were considered. Examples illustrate, that the MEC analysis helps to create a community concept that is focused on the targeted customers. It is supporting the creative process of finding community functions and features that are fitting or can be linked to the existing cognitive structures.     

Students' Argumentative Writing Skills in Science and First-Language Education: Commonalities and differences

The ability to build arguments is a crucial skill and a central educational goal in all school subjects including science as it enables students to formulate reasoned opinions and thus to cope with the increasing complexity of knowledge. In the present cross-sectional study, we examined the domain-specificity of argumentative writing in science by comparing it with a rather general type of argumentation as promoted in first-language education and with formal reasoning to gain insight into different forms of argumentation on theoretical and empirical levels. Using a paper-and-pencil test, we analyzed written argumentations and the reasoning abilities of 3,274 Grade-10 students in German secondary schools. Correlation and multiple regression analyses as well as a qualitative analysis of students' answers to a subset of tasks in the domains of science and first-language education were conducted. Results showed moderate relations between argumentation in science, argumentation in first-language education, and reasoning. Half of the variance in argumentation in science was explained by individual differences in argumentation in first-language education and reasoning. Furthermore, the examination of written arguments revealed differences, for example, in students' weighing of pros and cons. We assume that the familiarity of the underlying scientific information may play an essential role in the argumentation process and posit that it needs to be investigated in more detail. Overall, the study indicates that investigating the argumentational abilities of learners in first-language education and reasoning abilities can help to shed light on the domain-specificity of argumentation in science.     

Fluid dynamical analysis of the distribution of ink jet printed biomolecules in microarray substrates for genotyping applications

Oligonucleotide microarrays are tools used to analyze samples for the presence of specific DNA sequences. In the system as presented here, specific DNA sequences are first amplified by a polymerase chain reaction (PCR) during which process they are labeled with fluorophores. The amplicons are subsequently hybridized onto an oligonucleotide microarray, which in our case is a porous nylon membrane with microscopic spots. Each spot on the membrane contains oligonucleotides with a sequence complementary to part of one specific target sequence. The solution containing the amplicons flows by external agitation many times up and down through the porous substrate, thereby reducing the time delaying effect of diffusion. By excitation of the fluorophores the emitted pattern of fluorophores can be detected by a charge-coupled device camera. The recorded pattern is a characteristic of the composition of the sample. The oligonucleotide capture probes have been deposited on the substrate by using noncontact piezo ink jet printing, which is the focus of our study. The objective of this study is to understand the mechanisms that determine the distribution of the ink jet printed capture probes inside the membrane. The membrane is a porous medium: the droplets placed on the membrane penetrate in the microstructure of it. The three-dimensional (3D) distribution of the capture probes inside the membrane determines the distribution of the hybridized fluorescent PCR products inside the membrane and thus the emission of light when exposed to the light source. As the 3D distribution of the capture probes inside the membrane eventually determines the detection efficiency, this parameter can be controlled for optimization of the sensitivity of the assay. The main issues addressed here are how are the capture probes distributed inside the membrane and how does this distribution depend on the printing parameters. We will use two model systems to study the influences of different parameters: a single nozzle print head jetting large droplets at a low frequency and a multinozzle print head emitting small droplets at a high frequency. In particular, we have investigated the effects when we change from usage of the first system to the second system. Furthermore, we will go into detail how we can obtain smaller spot sizes in order to increase the spot density without having overlapping spots, leading eventually to lower manufacturing costs of microarrays. By controlling the main print parameters influencing the 3D distribution inside the porous medium, the overall batch-to-batch variations can possibly be reduced.
