Differential effects of reading trainings on reading processes: a comparison in Grade 2

Phonics, fluency, and reading strategy trainings are evidence-based interventions that foster the reading skills of poor readers in primary school. The purpose of the present study was to compare differential effects of the three types of trainings on the efficiency of component processes on word, sentence, and text level immediately after the training and at a 3-month follow-up. The 235 poor readers were randomly allocated to one of the reading interventions or to a control condition. All interventions consisted of 25 sessions that were scheduled twice a week and lasted 45 min. Results indicated short-term effects of the phonics training and the strategy training on the efficiency of a broad range of word-level and sentence-level processes. None of the treatment effects persisted over the long term, indicating the need for instructional efforts to regularly practice the acquired skills after the actual training.     

What factors motivate male and female Generation Z students to become engaged as peer teachers? A mixed-method study among medical and dental students in the gross anatomy course

Peer-teaching is widely established in anatomy teaching and offers well-described advantages. Nevertheless, at Ulm University, Germany, a reduction in the number of peer teacher applicants for the dissection course was observed. This study examined factors related to the attractiveness of a position as a peer teacher for Generation Z students. Participants of the gross anatomy course were asked to evaluate factors influencing the attractiveness of a peer teacher position using a six-point Likert scale. Additionally, open-ended questions were analyzed qualitatively. Sex-specific subgroup analysis was performed comparing students of low and high motivation to apply for a tutorship. Of the 374 students who participated in this study (response rate 53%), 38% stated that they were intending to apply as peer teachers. Data indicated that students displayed intrinsic motivation to apply for a tutorship because of the opportunity to improve their anatomy knowledge and/or their pleasure in teaching. In contrast, extrinsic factors like remuneration of the tutorship and its relevance for their curriculum vitae were least important. Anatomy educators underestimated the demotivating factor of the workload associated with the tutorship and encouraged students less frequently to apply than peer teachers. Only minor sex-specific differences could be identified. Nevertheless, female students were encouraged less frequently to apply than their male peers. In summary, Generation Z students apply as peer teachers because they are enthusiastic about the task. To motivate students to commit to extracurricular activities like a tutorship, anatomy educators should actively encourage students—particularly females—more frequently to apply.     

The role of metacognitive competences in the development of school achievement among gifted adolescents

Gifted underachievers perform worse in school than would be expected based on their high intelligence. Possible causes for underachievement are low motivational dispositions (need for cognition) and metacognitive competences. This study tested the interplay of these variables longitudinally with gifted and non-gifted students from Germany (N = 341, 137 females) in Grades 6 (M = 12.02 years at t1) and 8 (M = 14.07 years). Declarative and procedural metacognitive competences were assessed in the domain of reading comprehension. Path analyses showed incremental effects of procedural metacognition over and above intelligence on the development of school achievement in gifted students (β = .139). Moreover, declarative metacognition and need for cognition interactively predicted procedural metacognition (β = .169), which mediated their effect on school achievement.     

Only a Matter of Education Policy Ideals? German Professors’ Perception of the Bologna Process

Recently, it has been discussed how actors at universities perceive the Bologna Process. However, there is a lack of understanding about the determinants influencing attitudes towards the reform. In particular, the relation between education policy ideals and perceptions of the Bologna Process has gone unobserved. Based on a survey at three universities in North Rhine‐Westphalia in Germany, this article shows that a congruence of education policy ideals with the goals of the Bologna Process leads to a more positive perception of the reform. Ordinary least squares (OLS) regression models show that these findings are stable when controlled for socio‐demographic characteristics, changes of everyday work and involvement in the implementation of the Bologna Process. Thus, it is worthwhile to take into account the education policy ideals of involved actors when analysing perceptions of educational reforms.     

Transport and separation of micron sized particles at isotachophoretic transition zones

Conventionally, isotachophoresis (ITP) is used for separation of ionic samples according to their electrophoretic mobilities. We demonstrate that the scope of ITP applications may be extended toward particle concentration and separation. Owing to the distributions of electrolyte concentration and electric field inside a transition zone between two electrolytes, a number of different forces act on a small particle. As far as possible, we provide estimates for the order of magnitude of these forces and analyze their scaling with the particle size and the electric-field strength. Furthermore, we experimentally demonstrate that polymer beads of 5 μm diameter dispersed in a high mobility “leading” electrolyte are picked up and carried along by an ITP transition zone which is formed with a low mobility “trailing” electrolyte. By studying the particle positions and trajectories, we show that impurities in the electrolytes play a significant role in the experiments. Additionally, it is experimentally shown that different types of beads can be separated at an ITP transition zone. In particular, beads of 1 μm diameter are not carried along with the transition zone, in contrast to the 5 μm beads. The presented technique thus adds to the portfolio of electrokinetic transport, concentration, and separation methods in microfluidics.     

Mobilisieren und Optimieren

Looking at the conflictual constitution of educational systems by equality and excellence, this paper examines the discursive formation of two political rationalities in the contemporary German educational system that are directly opposed. While early childhood and primary education discourses are dominated by a terminology of equity, tertiary education institutions such as universities are described with a terminology of excellence that has become a reference point for political interventions and institutional reform processes.Taking up the theoretical position of hegemony-theory, governmentality studies and system theory, the paper analyzes the rules of justification these hegemonic discourses refer to by employing a discourse analysis of strategic, conceptional, and institutional texts of the German education policy discourse between 2003 and 2010. The paper puts forth the thesis that mobilizing and optimizing represent the common principles of equality and excellence as rationalities of the maximal mobilization of educational ressources.     

Lexical Quality and Reading Comprehension in Primary School Children

In a cross-sectional study, we examined the relationship between the quality of lexical representations and text comprehension skill in German primary school children (Grades 1–4). We measured the efficiency and accuracy of orthographical, phonological, and meaning representations by means of computerized tests. Text comprehension skill was assessed with a standardized reading test with questions requiring recognition of text information and inferencing. Both the accuracy of and the efficiency of access to the three types of lexical representations contributed to explaining interindividual variation in text comprehension skill. Results from a path-analytic model suggest a specific causal order of the three components of lexical quality with the quality of meaning representations partly mediating the effects of form representations.

Comprehension of Multiple Documents With Conflicting Information: A Two-Step Model of Validation

In this article, we examine the cognitive processes that are involved when readers comprehend conflicting information in multiple texts. Starting from the notion of routine validation during comprehension, we argue that readers' prior beliefs may lead to a biased processing of conflicting information and a one-sided mental model of controversial issues (text-belief consistency effect). An important distinction is that such biases occur routinely as a by-product of basic comprehension processes. However, readers can actively engage in strategies that work against the biasing effects of prior beliefs when they possess the relevant cognitive resources and are motivated to activate them. A review of published studies that examined belief effects in multiple text comprehension supports the two-step model of validation. We discuss implications of this model for multiple text comprehension and educational practice and delineate directions for future research.
