Die Stellung der Akkreditierungsbehörden im Hochschulrecht – ein Fehler der Verfassungsgesetzgebung?
Bettina Perthold-Stoitzner 《Zeitschrift für Hochschulrecht, Hochschulmanagement und Hochschulpolitik: zfhr》2008,7(6):165-170
Durch das "Bundesverfassungsgesetz, mit dem das Bundes-Verfassungsgesetz geändert und ein Erstes Bundesverfassungsrechtsbereinigungsgesetz erlassen wird", BGBl I 2008/2, wurden die Verfassungsbestimmungen des FHStG und des UniAkkG über die Weisungsfreistellung der genannten Akkreditierungsorgane in einfache bundesgesetzliche Bestimmungen umgewandelt. Der Beitrag geht der Frage nach, ob diese Umwandlung zu einem verfassungswidrigen Zustand geführt hat. 相似文献

This paper offers a typology of forms and uses of abduction that can be exploited to better analyze abduction in proving processes.
Based on the work of Peirce and Eco, we describe different kinds of abductions that occur in students’ mathematical activity
and extend Toulmin’s model of an argument as a methodological tool to describe students’ reasoning and to classify the different
kinds of abduction. We then use this tool to analyze case studies of students’ abductions and to identify cognitive difficulties
students encounter. We conclude that some types of abduction may present obstacles, both in the argumentation when the abduction
occurs and later when the proof is constructed. 相似文献

Mit der UG-Novelle 2009 wurden die Regelungen über die Einrichtung gemeinsamer Studienprogramme von Universit?ten mit anderen
in- und ausl?ndischen postsekund?ren Bildungseinrichtungen ausgebaut. Der Beitrag besch?ftigt sich mit diversen Fragestellungen,
die sich im Zusammenhang mit der praktischen Umsetzung der Regelungen stellen, und weist auf ungel?ste Probleme in diesem
Zusammenhang hin. 相似文献

ABSTRACTBackground: Recent developments in STEM and computer science education put a strong emphasis on twenty-first-century skills, such as solving authentic problems. These skills typically transcend single disciplines. Thus, problem-solving must be seen as a multidisciplinary challenge, and the corresponding practices and processes need to be described using an integrated framework.Purpose: We present a fine-grained, integrated, and interdisciplinary framework of problem-solving for education in STEM and computer science by cumulatively including ways of problem-solving from all of these domains. Thus, the framework serves as a tool box with a variety of options that are described by steps and processes for students to choose from. The framework can be used to develop competences in problem-solving.Sources of evidence: The framework was developed on the basis of a literature review. We included all prominent ways of domain-specific problem-solving in STEM and computer science, consisting mainly of empirically orientated approaches, such as inquiry in science, and solely theory-orientated approaches, such as proofs in mathematics.Main argument: Since there is an increasing demand for integrated STEM and computer science education when working on natural phenomena and authentic problems, a problem-solving framework exclusively covering the natural sciences or other single domains falls short.Conclusions: Our framework can support both practice and research by providing a common background that relates the ways, steps, processes, and activities of problem-solving in the different domains to one single common reference. In doing so, it can support teachers in explaining the multiple ways in which science problems can be solved and in constructing problems that reflect these numerous ways. STEM and computer science educational research can use the framework to develop competences of problem-solving at a fine-grained level, to construct corresponding assessment tools, and to investigate under what conditions learning progressions can be achieved. 相似文献

This study introduces a peri‐urban context of poverty to the study of child development in Africa in contrast to the more typical assessments in middle‐class and rural contexts. Spot observations were used to assess universal caregiving behaviors toward seventy‐six 3‐month‐old infants. Results show that middle‐class infants experienced distal parenting behaviors instantiated by mothers, whereas rural children experienced proximal parenting practices in interactions with others. Infants growing up in poverty had mothers and other caretakers involved at mostly low levels. They experienced low levels of body contact, body stimulation, and object stimulation, and high levels of face‐to‐face positions. The study indicates that caregiving in the context of poverty does not necessarily follow familiar pathways and needs to be contextualized accordingly. 相似文献

Six US first-year university students in humanities or social science degree programmes were interviewed while solving 4 tasks on continuity and asymptotes in a required mathematics course. The focus was on how the students referred to the definitions or to the concept images when solving the tasks and if partial understandings appeared. Partial understanding denotes when the definition or the concept image has correct parts but essential parts are missing or incoherencies occur. Some students confused continuity with differentiability or perceived it as a graph not having holes, which is also reported by other studies. Another misconception that emerged is to perceive points on the x-axis as non-continuous. The partial understandings of asymptotes were related to the vertical asymptote as it was confused with a function property. Some students referred to the definitions when correctly solving some of the tasks and some students with coherent concept images were successful solving some of the tasks even when they did not refer to the definitions. 相似文献

This article reports about our efforts to determine engineering students' competence in mathematics. Our research is embedded in a larger project, KoM@ING–Modeling and developing competence: Integrated IRT based and qualitative studies with a focus on mathematics and its usage in engineering studies, within the program Modeling and Measuring Competencies in Higher Education (KoKoHS). KoKoHS provides the umbrella organization of several research projects addressing the modeling and measuring of competences at the college level. KoM@ING aims to model the role of engineering students' mathematical competences for their studies from both a quantitative and a qualitative perspective.Here, we report the development of a large-scale instrument assessing engineering freshmen's competence in mathematics by applying Rasch analysis to determine measures for item difficulties and student abilities. Several analyses were performed to provide insights into the measures' reliability and validity. In particular, to examine cognitive validity, we scrutinized students' think-aloud protocols when solving the items to investigate their problem solving abilities as a proxy for item difficulty. Overall, we found first evidence that our instrument is suitable to assess engineering freshmen's competence in mathematics. This instrument may be helpful to conduct further research and to inform those concerned with college organization and policy. 相似文献
