The theory-practice debate has been a perennial issue in initial teacher education (ITE). By reporting a mixed-methods study in an ITE programme characterized by a university-based ‘theory-first’ approach in Hong Kong, this study offers useful empirical evidence to analyse the theory-practice issue. 346 student teachers of a BEd Programme participated in the quantitative survey, 15 of whom were interviewed. The quantitative findings showed significant positive correlations between three types of perceived professional competence and two aspects of student teachers’ engagement with the theory-practice link. The qualitative findings offered an in-depth understanding of the ways in which student teachers connected theoretical knowledge learned in ITE coursework and practical experience in ITE fieldwork in developing their professional competence: (1) theoretical knowledge as a guide for professional decisions and a tool for reflection on practice; (2) practicalizing theoretical knowledge: adapting theoretical knowledge to practice situations. In the process of engagement, theoretical knowledge was transformed and adapted to practice situations when student teachers coped with the challenges of the teaching contexts in their ITE fieldwork. While affirming the value of student teachers’ engagement with the theory-practice link, the findings of the study shed light on ITE practices for preparing student teachers for such engagement.  相似文献

Despite recent research findings that implicate a long list of student variables that predict reading success or failure, these predictor variables have not been considered in the context of contemporary models of multitiered schoolwide reading intervention. This longitudinal, retrospective study follows 668 kindergarten and first-grade students identified as at risk for later reading difficulties through third grade. Key predictor variables were examined to determine their validity for predicting initial status and growth on oral reading fluency, third-grade oral reading fluency, and third-grade performance on a standardized test of reading. Results are provided in light of the instructional model provided. Implications for instruction and assessment are discussed.  相似文献

This paper describes research that explored the question of whether or not it is possible to characterise and teach a single type of educationally productive talk. We analysed and compared the quality of children's interactional strategies when jointly working on a reasoning task and a psycholinguistic task. The latter involved writing an integrated summary of three related texts. Sixth grade primary school children (11–12 years old) solved these two tasks as pre- and post-tests before and after training in the use of ‘Exploratory Talk’ (ET) to think together and argue as well as in strategies for producing summaries. After training, children improved substantially in the use of ET when solving the reasoning but not the psycholinguistic task. However, using ethnography of communication methods to analyse the talk further around the latter task revealed that both the number and quality of communicative events and acts increased importantly. These changes were accompanied by a significant improvement in the quality of the summaries produced. These findings suggest that the requirement for explicit reasoning in the definition and analysis of ET may be task dependent. To account for the common features of the educationally productive talk in the two settings, we propose the more inclusive concept of co-constructive talk to characterise the inter-subjective orientation, social ground rules and communicative actions that support effective collaboration, co-ordination and creativity.  相似文献

The evolution of the World Wide Web has encouraged a huge surfacing of e‐learning technologies over recent years. Often, such technology is rolled out devoid of consideration towards the way in which students process and assimilate information. To date, there exists inconclusive and contradictory evidence concerning learnability effects of single‐ and dual‐model systems in education. To overcome this, we advocate that the design of e‐learning systems requires a managed mix of elements grounded in cognitive psychology. In this paper, we report the results of a study concerned with determining an effective mix of multimedia elements. This is with regard to the situated learnability effects of single‐ and dual‐modal systems tested via ‘text only’ and ‘text and auditory–verbal’ conditions. We report on these experiments using science computer‐assisted teaching and music‐oriented learning environment, e‐learning environments developed to act as test platforms for this research. The results indicated that simultaneous presentation of identical information via text and narration was associated with enhanced learnability.  相似文献

手工克隆,一种制作与动物基因相同的拷贝的新方法,不仅比现有的方式花费少、操作简便,而且看来效果更好。目前,克隆的关键仪器是“显微操作器”,它价格高昂,并且需要熟练的技术人员在显微镜下钳住一个卵细胞,插入一根极其精细的针头以吸出其核仁,再用另外一根针头注入待克隆动物的核仁,还有一种选择就是融合一空的卵细胞和待克隆动物的一个细胞。两种方法都是极其复杂且非常耗时的。  相似文献

Most course evaluation in higher education is designed and conducted by university staff and rarely are students given central responsibility for planning and implementing an evaluation. Involving students as partners in educational evaluation may offer them authentic ways to develop professional skills. We describe an ‘education option’ that involved five students in designing and conducting an evaluation of the Virtual Anatomy Tutor (VAT), an online learning resource for medical students, and report both student and staff reflections on the process. The experience gained by the five students can be transferred to other settings which provide opportunities for student designed and conducted evaluation of learning resources.  相似文献

The relative contributions of higher education and schools, and hence the conceptual and practical aspects of ITE, to student teachers’ professional learning have been an issue of concern in teacher education. This article reports a mixed-methods study showing the relationship between student teachers’ engagement with the practical and conceptual aspects of a Postgraduate Diploma in Education (PGDE) Programme in Hong Kong and different facets of their perceived professional competence. One hundred and thirty-two student teachers participated in the quantitative survey of whom seven were interviewed. The findings reveal that experiences associated with learning the pragmatic facets of professional practice were more valued by student teachers compared to learning the conceptual aspects of ITE. Yet, in terms of relationship with professional competence, student teachers’ engagement with the practical aspects of ITE was related to competence in classroom teaching, whereas their engagement with the conceptual aspects contributed to their mastery of professional knowledge, competence in classroom teaching and competence in interacting with stakeholders. The study illuminates the distinctive contributions of schools and higher education in ITE. While acknowledging the important role of schools in providing a setting for practical work, this study affirms the distinctive contribution of higher education in equipping student teachers with practical and conceptual tools in the preparation of professionally competent teachers.  相似文献

Psychological science has identified positive classroom management and climate building strategies as a key element in developing and maintaining effective learning environments. In this article, we review the literature that has identified effective strategies that build classroom climates to maximize student learning and minimize disruption. In general, these strategies indicate a shift away from reactive and punitive approaches towards an emphasis on instructional and preventive approaches, including setting clear expectations, appropriate curriculum to increase student engagement, positive acknowledgment, and building relationships between students and teachers. Emerging research has also begun to identify features of culturally responsive classroom management that can engage and build relationships for a diverse student population.  相似文献

Dr. Maria Montessori was a perceptive observer of the learning processes of children, and nowhere is this revealed more clearly than in her approach to language. She viewed reading as the ultimate abstraction of language rather than a specific skill to be taught. Decoding is the skill to be taught. The concept of indirect and direct preparation for learning is of major importance in the rich heritage she gave us. She saw the existence of an epigenesis of intellectual functioning, which implies that the experiential roots of a given schema, or learned behavior, will lie in antecedent activities that may be quite different in structure from the schema to be learned. She used this principle effectively. This article discusses how Montessori’s method and materials address the indirect and direct preparation for learning written language.  相似文献
