Effects of a training intervention to foster argumentation skills while processing conflicting scientific positions     

Markus H. Hefter  Kirsten Berthold  Alexander Renkl  Werner Riess  Sebastian Schmid  Stefan Fries 《Instructional Science》2014,42(6):929-947

Argumentation skills play a crucial role in science education and in preparing school students to act as informed citizens. While processing conflicting scientific positions regarding topics such as sustainable development in the domain of ecology, argumentation skills such as evaluating arguments or supporting theories with evidence are beneficial for developing deep understanding and well-grounded conclusions. We developed a 50-min training intervention to foster argumentation skills in the domain of ecology on topics related to sustainable development and analyzed its effects in a control-group design: (a) training intervention to foster argumentation skills (n = 41), (b) no such training intervention (n = 42). Results showed that this short-term training intervention successfully fostered three components of argumentation skills (i.e., evaluative knowledge, generative knowledge, and argument quality) and declarative knowledge about argumentation. The positive effect on declarative knowledge was stable 1 week after the training and it was mediated by learning processes during the training intervention: self-explaining the principles of argumentation underlying the video-based examples mediated the effect on declarative knowledge 1 week after the training. In short, the training intervention is an effective instructional method to enhance argumentation skills as well as declarative knowledge about argumentation.  相似文献   

Strategic Management in the Media: Theory to Practice,by Lucy Küng     

Markus Will 《媒体管理杂志》2013,15(1):46-53

Abstract

Management has always been about communications. Business strategy in particular can only work, if implemented. Part of the process is communicating strategy to all company's stakeholders. The more team‐orientated a management style the more communications becomes a key success factor. By the same token, there has never been a management discipline for communications in its own right comparable to all the others that have developed over time: Neither Marketing nor HR nor even Finance were part of the original settings as, for example, laid out by Erich Gutenberg in the 1960s. All these “subs”; were initiated by increasing specialisation of business administration and developed to mature disciplines.

This article will argue for yet another management discipline, communications management. The reasons are mainly twofold: on the one hand there are increasing needs on different types of communications even without the world‐wide web (such as financial communications), which must be integrated in one holistic approach. And on the other hand there are increasing new challenges caused by the digital economy (such as customer related communications), which will have to be integrated in an even advanced holistic management approach. This article will combine both reasons, but mainly focus on the first aspect.  相似文献   

Cognitive and motivational profile shape predicts mathematical skills over and above profile level     

Giselle Reimann  Markus Stoecklin  Kristen Lavallee  Janine Gut  Marie‐Claire Frischknecht  Alexander Grob 《Psychology in the schools》2013,50(1):37-56

The interpretation of subtest profiles from intelligence testing remains popular among many practitioners who use subtest performance to draw diagnostic conclusions, in spite of criticism by some researchers, who point to the low reliability and predictive validity of subtest scores in predicting achievement outcomes. Prior research outlines two approaches to the study of subtest variation: the examination of interindividual variation in specific cognitive domains or subtests as compared to a standard sample, and the examination of intraindividual strengths and weaknesses, regardless of overall level. The present study seeks to add to knowledge in this field with data from 567 children ages 5 to 10 years who exhibit meaningful subtest variation on a new test of intellectual abilities. Results from the present sample point to statistically significant utility, with small to medium effects, of intraindividual cognitive and motivational profile shape over and above profile level in predicting mathematical skills. We discuss implications for school psychological and educational assessment research.  相似文献   

The Role of Motor Competences in Predicting Working Memory Maintenance and Preparatory Processing     

Sebastian Ludyga  Manuel Mücke  Keita Kamijo  Christian Andrä  Uwe Pühse  Markus Gerber  Christian Herrmann 《Child development》2020,91(3):799-813

The purpose of the study was the examination of the longitudinal association between motor competences and changes in preparatory processing during a task requiring working memory maintenance. At baseline, 52 Caucasian children aged 10–12 years completed the MOBAK-5 test battery and a Sternberg task, whereas the cue-P300 and the initial contingent negative variation (iCNV) were recorded via electroencephalography. After 9 months, the Sternberg task was administered again to assess changes in these neurophysiological indices and behavioral performance. Path analyses revealed that motor competences predicted the change in cue-P300 and iCNV from baseline to follow-up. The present findings indicate that the cognitive control strategy during a task demanding working memory maintenance changes as a function of children's baseline motor competences.  相似文献   

Interference screws vs. suture anchors for isolated medial patellofemoral ligament femoral fixation: A systematic review     

Filippo Migliorini  Alice Baroncini  Jörg Eschweiler  Markus Tingart  Nicola Maffulli 《运动与健康科学(英文)》2022,11(1):123-129

Purpose:The present study aimed to systematically review and compare 2 femoral autograft fixation techniques,namely,interference screws and suture anchors,for isolated medial patellofemoral ligament reconstruction in patients with recurrent patellofemoral instability at mid-to long-term follow-up.Methods:A literature search was performed in September 2020.All studies reporting the outcomes of primary isolated medial patellofemoral ligament reconstruction for recurrent patellofemoral instability were considered for inclusion.Only studies reporting the type of femoral autograft fixation under examination were considered.Studies reporting data from patients with elevated tibial tuberosity-tibial groove,patella alta,and/or Dejour’s trochlear dysplasia types C and D,were not included.Only articles reporting data with a minimum follow-up period of 18 months were considered.Results:Data from 19 studies(615 patients)were retrieved.The overall age was 24.4±6.7 years(mean±SD).The mean follow-up was 46.5±20.9 months.There were 76 patients in the anchor group and 539 in the screw group.Comparability was found with regard to age and follow-up duration between the 2 study groups.There was comparability between the Kujala,Lysholm,and Tegner scores at baseline.At the last follow-up,no worthy differences were found in terms of mean Kujala(+2.1%;p=0.04),Lysholm(+1.7%;p=0.05),and Tegner(+15.8%;p=0.05)scores.Although complications occurred almost exclusively in the screw cohort,no statistically significant difference was found.Conclusion:Femoral autograft fixation through interference screws or suture anchors report similar clinical scores and rate of apprehension test,persistent joint instability,re-dislocations,and revisions.These results must be interpreted within the limitations of the present study.  相似文献   

Development of a magnetic immunosorbent for on-chip preconcentration of amyloid β isoforms: Representatives of Alzheimer's disease biomarkers     

Svobodova Z  Reza Mohamadi M  Jankovicova B  Esselmann H  Verpillot R  Otto M  Taverna M  Wiltfang J  Viovy JL  Bilkova Z 《Biomicrofluidics》2012,6(2):24126-2412612

Determination of amyloid β (Aβ) isoforms and in particular the proportion of the Aβ 1-42 isoform in cerebrospinal fluid (CSF) of patients suspected of Alzheimer's disease might help in early diagnosis and treatment of that illness. Due to the low concentration of Aβ peptides in biological fluids, a preconcentration step prior to the detection step is often necessary. This study utilized on-chip immunoprecipitation, known as micro-immunoprecipitation (μIP). The technique uses an immunosorbent (IS) consisting of magnetic beads coated with specific anti-Aβ antibodies organized into an affinity microcolumn by a magnetic field. Our goal was to thoroughly describe the critical steps in developing the IS, such as selecting the proper beads and anti-Aβ antibodies, as well as optimizing the immobilization technique and μIP protocol. The latter includes selecting optimal elution conditions. Furthermore, we demonstrate the efficiency of anti-Aβ IS for μIP and specific capture of 5 Aβ peptides under optimized conditions using various subsequent analytical methods, including matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS), capillary electrophoresis, microchip electrophoresis, and immunoblotting. Synthetic Aβ peptides samples prepared in buffer and spiked in human CSF were analyzed. Finally, on-chip immunoprecipitation of Aβ peptides in human CSF sample was performed.  相似文献   

Moderate-to-vigorous physical activity,executive functions and prefrontal brain oxygenation in children: A functional near-infrared spectroscopy study     

Manuel Mücke  Christian Andrä  Markus Gerber  Uwe Pühse 《Journal of sports sciences》2018,36(6):630-636

Despite accumulating evidence that regular exercise improves executive functioning, the underlying neurophysiological mechanisms have rarely been investigated. The present study aimed to compare cognitive performance as well as task-specific concentration changes in oxygenated haemoglobin in the prefrontal cortex between children with higher and lower moderate-to-vigorous physical activity (MVPA). Physical activity was measured over 7 consecutive days using actigraphy. Afterwards, participants (N = 50) completed verbal fluency tests (VFTs) and mental arithmetic (MA) for the assessment of cognitive flexibility and working memory capacity. During the tasks, changes of oxygenated haemoglobin were measured with functional near-infrared spectroscopy. Using average MVPA of 11-year-old children as cut-point, the sample was divided into children with lower and higher MVPA. Analyses of variance revealed no significant differences in correct and false responses on the cognitive tests between groups. With regard to oxygenated haemoglobin, no group differences were found for concentration changes in response to the cognitive tasks. In conclusion, VFTs and MA increased children’s activation in prefrontal regions associated with cognitive flexibility and working memory, respectively. However, these executive functions and cortical activation were not different between children with lower and higher MVPA.  相似文献   

Inclusive vocational schools in Canada and Germany. A comparison of vocational pre-service teachers′ attitudes,self-efficacy and experiences towards inclusive education     

Susanne Miesera  Markus Gebhardt 《欧洲特需教育杂志》2018,33(5):707-722

Both Canada’s and Germany’s school systems are transitioning into inclusive education systems. This transition is also happening in vocational schools. This paper addresses the new demands that vocational teachers face, due to the introduction of inclusive education in Germany and Canada, by examining Canadian and German pre-service vocational teachers’ attitudes, self-efficacy and experiences related to inclusive education. The study identifies significantly more positive ratings in the Canadian sample across all the three scales. We conclude that the different ratings relate to different school systems, experiences with inclusion and the teacher education systems. Based on these research findings, recommendations for teacher education are discussed.  相似文献
