This study employs narrative methods to give a holistic view of the experiences of five mature age preservice teachers in a semester unit of science education. The unit was designed to help teachers examine and make explicit their ideas about science and science teaching and consider ways in which they might put those ideas into practice. The pivotal theme, around which the teachers' experiences could be organised, was found to be learning science. The preservice teachers expressed a need for a supportive learning environment in which concepts were built gradually and introduced using concrete examples. Previous science experience was found to be a major influence on the attitudes the participants brought to the present course. A lack of previous experience or negative past experiences were a major cause of anxiety. Gender was also important as it had limited the science experiences available to some participants in the past and continued to influence the way they participated in classes during the semester. Specializations: primary science, science teacher education, primary school field experience. Specializations: formation of teachers' knowledge, leadership, teacher change, school reform.  相似文献

The genetic and environmental origins of individual differences in mathematical self-evaluation over time and its association with later mathematics achievement were investigated in a UK sample of 2138 twin pairs at ages 9 and 12. Self-evaluation indexed how good children think they are at mathematical activities and how much they like those activities. Mathematics achievement was assessed by teachers based on UK National Curriculum standards. At both ages self-evaluation was approximately 40% heritable, with the rest of the variance explained by non-shared environment. The results also suggested moderate reciprocal associations between self-evaluation and mathematics achievement across time, with earlier self-evaluation predicting later performance and earlier performance predicting later self-evaluation. These cross-lagged relationships were genetically rather than environmentally mediated.  相似文献

This review investigates the state of teacher self- and collective efficacy research conducted from 1998 to 2009. Two hundred and eighteen empirical articles published in 1998–2009 were examined for key characteristics and compared to research published in the previous 12 years (i.e., 1986–1997). Results from the review show increases in overall teacher efficacy research, methodological diversity, domain specificity, internationalization, and focus on collective efficacy. Continuing problem areas were a lack of attention to the sources of teacher efficacy, continued measurement and conceptual problems, a lack of evidence for the links between teacher efficacy and student outcomes, and uncertain relevance of teacher efficacy research to educational practice. An outline of directions for future teacher efficacy research is provided.  相似文献

This article examines the effect that postsecondary education has on earnings and the duration of time spent in the Social Security disability programs for young persons who are deaf or hard of hearing. Our hypothesis is that investments in postsecondary training increase the likelihood of employment for persons who are deaf or hard of hearing and thus reduce dependency on disability-related income support programs. A longitudinal data set based upon records from the National Technical Institute for the Deaf and Social Security administrative records is used for this analysis. We find that those who graduate, even those who graduate with vocational degrees, experience significant earnings benefits and reductions in the duration of time spent on federal disability programs when compared with those who do not graduate with a degree. This finding suggests that reductions in the duration of time spent on Social Security programs are not limited to those with the highest level of scholastic aptitude and that investments in post-secondary education can benefit a broad group of deaf and hard-of-hearing persons. In addition, the data show that individuals who attend college, but withdraw before graduation, fair no better economically than individuals who never attended college.  相似文献

Being active in civic organizations can be expressed in multifarious forms of participation and commitment. With regard to individuals, the learning context it provides fosters personal development, sympathy for other perspectives, and social competencies in general and is, thus, particularly meaningful for young people in their second and third decades. With regard to organizations, civic participation strengthens the integration and dynamic adaptation of institutions to changing environments and, on a macro-level, raises social cohesion. The contexts of participation are various: not only in educational institutions and the world of work, but also in clubs, organizations and less formal groups, which are involved in social and political issues. Socio-structural and motivational factors, but also belonging to social networks determine the involvement in such forms of civic participation. Additionally, there is evidence of a mutual reinforcement of participation in different contexts. This is shown by the results of the DJI-Survey AID:A 2009.  相似文献

In Germany, teachers give a recommendation on the type of school a student should attend after primary school. In some federal states, access to a more demanding school type is restricted to students holding an appropriate recommendation. In a first step, we discuss different theories and approaches as to why a student??s social origin or migration background has an impact on the recommendation, irrespective of school performance. Then we test different hypotheses using data of a combined teacher, student, and parent survey, conducted from the 3rd grade on in Bavaria and Hessen. Overall, we have information on 1.644 students and 147 teachers. We find strong relationships between social origin and school recommendations as teachers take parents?? educational aspirations into account. Students?? positive school behavior has a positive impact on getting a recommendation for a higher school type; however, the influence of parents?? socio-economic status remains. The data show no evidence for children with migration backgrounds facing greater risks of receiving lower recommendations than other children??irrespective of their family language.  相似文献

The Bologna Process of higher education reform has led to a vast array of different programs of study in German teacher training. In this article, we firstly analyze the implementation of Bachelor programs in teacher training, comparing profession-oriented programs (i.e. those aiming to train students for the teaching profession from the beginning of studies) to polyvalent programs (i.e. those aiming at broad qualifications and including a late decision to become a teacher). Secondly, we investigate whether students enrolled in these study programs differ systematically in their subjective certainty about their career choice. To answer these questions, we analyze portfolios of documents related to teacher training programs from nine German universities that prepare students for teaching in the academic track. Additionally, we analyze data from N?=?2585 Bachelor and N?=?928 Master degree students. We found that most programs, even when they espouse polyvalence, require an early decision to become a teacher. Moreover, our data confirm findings from earlier studies indicating that student teachers are highly certain about their career choice from the very beginning, with students in polyvalent programs being slightly less certain than those in profession-oriented programs (d?=?0.32).  相似文献

Discussions concerning ??literacy?? make it clear that the domain of language has become a focal point for educational policy. In such discussions, language is primarily treated as a basic communication tool. This paper examines, from a philosophical perspective, how appropriate this approach to language is. The philosophical validity of this dominant tendency is analyzed with reference to the work of Wilhelm von Humboldt, Nietzsche, and Wittgenstein. Once the stable relationship conceived by Humboldt among the individual, language, and the world is lost, education displays its more distinctive features, which we see clearly in Nietzsche and Wittgenstein. Both of these philosophers focused their investigation on the rhetorical or performative aspects of language. In contrast to Nietzsche, however, Wittgenstein did not abandon the hope of finding in language the function of showing reality, even if what is said and what is shown remain incongruent. This perspective in Wittgenstein is salient against the dominant tendency, in which the mediating function of language is sought in the dimension of conformity and usefulness.  相似文献
