Parents with a migration background are underrepresented among parent representatives at schools in Germany. However, increased involvement of these parents is essential for a lively democratic culture. To explore the motivations of parents with migration background regarding their school involvement, interviews with N?=?31 parent representatives with migration background were content analysed, starting deductively from a set of categories according to the theory of planned behaviour. In the analysis, the main category ??attitude?? was deductively subdivided into ??motivation in the course of action/intrinsic value??, ??results and consequences regarding own interests?? and ??results and consequences regarding others/altruistic motivation??. ??Subjective norm?? was inductively differentiated into ??other parents??, ??teachers and leadership team?? and ??other persons/perceived general expectations??; ??perceived behavioural control?? was differentiated into the subcategories ??assertiveness and freedom from anxiety??, ??language competence??, ??socioeconomic background??, ??availability of time??, ??setting in school and school district?? and ??field expertise and know-how??. Additionally, ??habit?? was deductively established and retained as a main category. Analysis of 513 statements resulted in an interrater-agreement of ???=?0.82. Implications for working with parents in an intercultural context are discussed.  相似文献

We provide first evidence regarding the direct impact of educational mismatch on firm productivity. To do so, we rely on representative linked employer–employee panel data for Belgium covering the period 1999–2006. Controlling for simultaneity issues, time-invariant unobserved workplace characteristics, cohort effects and dynamics in the adjustment process of productivity, we find that: (i) a higher level of required education exerts a significantly positive influence on firm productivity, (ii) additional years of over-education (both among young and older workers) are beneficial for firm productivity, and (iii) additional years of under-education (among young workers) are detrimental for firm productivity.  相似文献

With regard to the moderate performance of German students in international large-scale assessments, one branch of German science education research is concerned with the construction and evaluation of competence models. Based on the theory-driven definition of competence levels, these models imply a correlation between the complexity of a question or a problem, its difficulty and the cognitive demands that are required to answer or solve it. The aim of the study was to apply two competence models in order to analyse the complexity of questions that chemistry teachers use to promote learning in class as well as to compare the results of this analysis. Two model-based coding schemes were constructed and evaluated on the basis of interrater reliability before analysing the teacher questions in 40 chemistry lessons. The results show that between 60 and 65 % of the questions refer to low complexity levels. Although there is a considerable correspondence between the results (69.2 %), neither model can be considered as redundant. These findings are discussed with regard to the level and the development of students’ skills in science.  相似文献

Higher and further education institutions are increasingly using social software tools to support teaching and learning. A growing body of research investigates the diversity of tools and their range of contributions. However, little research has focused on investigating the role of the educator in the context of a social software initiative, even though the educator is critical for the introduction and successful use of social software in a course environment. Hence, we argue that research on social software should place greater emphasis on the educators, as their roles and activities (such as selecting the tools, developing the tasks and facilitating the students' interactions with these tools) are instrumental in a social software initiative. To address this gap, we have developed a research agenda on the role of the educator in a social software initiative. Drawing on role theory, both as the basis for a systematic conceptualization of the educator role and as a guiding framework, we have developed a series of concrete research questions that address core issues associated with the educator roles in a social software context. We have provided recommendations for further investigations. By developing a research agenda, we hope to stimulate research that creates a better understanding of the educator's situation and develops guidelines to help educators carry out their social software initiatives. Considering the significant role an educator plays in the initiation and conduct of a social software initiative, our research agenda ultimately seeks to contribute to the adoption and efficient use of social software in education.  相似文献

The present study is the first to investigate the relationships between a multiple set of paranormal beliefs and the acceptance of evolution, creationism, and intelligent design, respectively, in Europe. Using a questionnaire, 2,129 students at secondary schools in Vienna (Austria) answered the 26 statements of the Revised Paranormal Belief Scale (R-PBS) and three statements about naturalistic evolution, creationism and intelligent design (ID). The investigated Austrian students showed an average R-PBS score of 82.08, more than 50% of them agreed with naturalistic evolution, 28% with creationism, and more than a third agreed with ID, the latter two closely correlated with each other. Females generally showed higher belief scores in the paranormal, creationism and ID. The agreement with naturalistic evolution correlated negatively with religious belief, but not with other paranormal beliefs, whereas the two non-scientific alternatives to evolution significantly correlated with both traditional and paranormal beliefs. Religious belief showed a significant positive correlation with other paranormal beliefs. All subscales of paranormal belief decreased during the eight grades of secondary school, as did acceptance of creationism and ID. However, the acceptance of naturalistic evolution did not correlate with age or grade. Possible reasons and implications for science education and the biology curriculum at Austrian secondary schools are discussed.  相似文献

Preservice teachers’ knowledge of proof by mathematical induction   总被引:2,自引:1,他引:1  
There is a growing effort to make proof central to all students’ mathematical experiences across all grades. Success in this goal depends highly on teachers’ knowledge of proof, but limited research has examined this knowledge. This paper contributes to this domain of research by investigating preservice elementary and secondary school mathematics teachers’ knowledge of proof by mathematical induction. This research can inform the knowledge about preservice teachers that mathematics teacher educators need in order to effectively teach proof to preservice teachers. Our analysis is based on written responses of 95 participants to specially developed tasks and on semi-structured interviews with 11 of them. The findings show that preservice teachers from both groups have difficulties that center around: (1) the essence of the base step of the induction method; (2) the meaning associated with the inductive step in proving the implication P(k) ⇒ P(k + 1) for an arbitrary k in the domain of discourse of P(n); and (3) the possibility of the truth set of a sentence in a statement proved by mathematical induction to include values outside its domain of discourse. The difficulties about the base and inductive steps are more salient among preservice elementary than secondary school teachers, but the difficulties about whether proofs by induction should be as encompassing as they could be are equally important for both groups. Implications for mathematics teacher education and future research are discussed in light of these findings.

In an experiment with 56 young adults, the hypothesis was tested that information about the format of an anticipated test improves metacognitive monitoring. Half of the participants were informed about the format of the test before they started studying a text about human genetics. The other half of the sample received the same information after studying the text. All participants then answered 15 true-false inference items about the contents of the text and judged their confidence in the correctness of each answer. Whereas experimental and control group did not differ in the number of correct answers, the confidence judgments in the experimental group were more accurate and discriminated better between correct and incorrect answers than the control participants’ judgments. Furthermore, the informed participants’ discrimination performance correlated positively with their domain-related prior knowledge. The results extend earlier findings concerning the role of the test format for monitoring processes.  相似文献
