Developmental remediation programs designed to raise achievement levels of underprepared students have proliferated in the past decade. Despite the fact that these programs employ a variety of teaching strategies, a substantial subgroup of developmental students are unsuccessful in current remediation programs. They need a different curricular approach. As the number of applicants declines and the demand for generating credit hours continues, the question is shifting from “Should less capable students be allowed to attend college?” to “What curriculum should be provided for these students?” The challenge for the '80s is to expand developmental education to include vocational education and post-secondary specialized education. 相似文献

This paper reports on a study that has mapped the stories of a group of women teacher educators. While the focus is on the period of change during the last 10 years from primarily teachers’ colleges to university‐based teacher education, the broader context of the individual women's lives is explored as well. The stories are mapped against each other and against relevant literature. In this way the study considers the challenge of change on the experiences of these women teacher educators. This study has been informed by feminist theory and has been constructed within a framework which is both narrative and collaborative. As Acker notes ‘one advantage of narrative is that history makes itself evident in the world of its actors’. In this way the intersections of the personal histories and biographies of the teacher educators within the social context in which they work are examined. These women teacher educators’ stories demonstrate similarities and differences in actions and reactions to the challenges they have faced in the last decade in teacher education. The similarities and differences are due to individual histories, career experiences and the character of the institutions in which they live their professional lives. In presenting this paper, the key focus is on reporting how the forces inherent in the changing nature of the educational environment have impacted on these teacher educators in such a way as to present challenges for each in the way they have developed in their profession as teacher educators. 相似文献

In many innovative science content professional development (PD) courses for teachers, science concepts are situated within pedagogical contexts, or in other words, science content is incorporated within contexts relevant to teaching and student learning. Pedagogical contexts are often used because they are believed to be engaging for teachers and to support content transfer to the classroom. However, few studies have investigated how pedagogical contexts serve to impact teacher engagement and science content learning. This qualitative case study examined K-8 in-service teachers?? interactions with pedagogical contexts in a chemistry PD course. Findings indicate that teachers??: (1) contribution of teaching experiences helped create a collegial learning environment, (2) sharing of concerns from classroom teaching directed content discussion and learning objectives, and (3) reflection on teacher and learner roles in the PD classroom led to persistence in chemistry-content learning. Implications for PD instructor use of pedagogical contexts in science content based PD are discussed. 相似文献

Of primary concern in professional development (PD) are the ways in which teachers transfer knowledge from PD to the classroom.
This qualitative case study of a chemistry PD course for elementary teachers investigates the first step in the transfer process
by examining why and how K-8 teachers consider transfer to the classroom. Motivations for considering transfer were the same
whether teachers only proposed how they could use PD content or teachers actively utilized PD experiments and concepts in
their own classrooms. Teacher learning of chemistry concepts, activities, and pedagogical strategies were motivating factors
for considering transfer. Teachers appropriated and adapted PD materials based on the specific learning needs of their own
students, the constraints of their teaching contexts, and their desired outcomes, including making science learning relevant
for students. Understanding teachers’ motivations and means of adaptations in considering PD can inform PD provider programs
how to be more effective and responsive to teacher needs. Furthermore, teachers’ active consideration of appropriations and
adaptations highlights how teachers leverage their expertise in shaping their PD experiences. 相似文献

This study examines how various components of a school-linking programme between Ireland and South Africa either support Development Education’s goal of sustainable, equitable partnerships that enable mutual learning between Northern and Southern countries or, instead, promote power imbalances that reify stereotypic images of weak, needy Southerners being cared for by powerful, benevolent Northerners. Ethnographic data from schools in both sites suggest that divergent assumptions about and priorities for Development Education in Ireland and South Africa, disproportionate exchange visits, socio-economic differences and an ‘inward’ South African focus versus a ‘global’ Irish focus set the stage for power imbalances within the linking programme. Recommendations for a conjointly conducted revision of the agenda for school-linking programmes are made. These centre on helping learners understand how issues of power and power imbalance function at the local, national and global levels. 相似文献

To improve search engine effectiveness, we have observed an increased interest in gathering additional feedback about users’ information needs that goes beyond the queries they type in. Adaptive search engines use explicit and implicit feedback indicators to model users or search tasks. In order to create appropriate models, it is essential to understand how users interact with search engines, including the determining factors of their actions. Using eye tracking, we extend this understanding by analyzing the sequences and patterns with which users evaluate query result returned to them when using Google. We find that the query result abstracts are viewed in the order of their ranking in only about one fifth of the cases, and only an average of about three abstracts per result page are viewed at all. We also compare search behavior variability with respect to different classes of users and different classes of search tasks to reveal whether user models or task models may be greater predictors of behavior. We discover that gender and task significantly influence different kinds of search behaviors discussed here. The results are suggestive of improvements to query-based search interface designs with respect to both their use of space and workflow. 相似文献
