The emphasis of this paper is on the derivation of design principles from qualitative analysis of student reflections based on their participation in authentic, collaborative and technology-mediated activities. This paper reports on the initial phases of a design-based research project at a comprehensive university in South Africa where the authentic nature of the activities contributed to the depth of student reflections and ultimately led to meaningful design principles based entirely on the experiences of students. Students’ reflective reports were analysed for their content using simple inductive coding techniques leading to the identification of themes and the derivation of design principles from further refinement of these themes. These design principles, therefore, have their origins in the specific theories underpinning the learning activities that were used in the teaching and learning process, and contribute once again in an innovative way to this same body of knowledge. This theory-driven praxis thus makes a contribution to both educational theory and teaching practice which is applicable across a variety of contexts and sectors worldwide. More importantly, this can be seen as meaningful research that is socially responsible, with a high theoretical and practical value, and of relevance to a wider international audience.  相似文献

Existing instruments for assessing student or teacher perceptions of characteristics of actual or preferred classroom psychosocial environment are unsuitable for one of the most important settings in science teaching, namely, the science laboratory class. Consequently, the Science Laboratory Environment Inventory (SLEI), was designed to assess student or teacher perceptions of seven scales:Teacher Supportiveness, Student Cohesiveness, Open-Endedness, Integration, Organization, Rule Clarity andMaterial Environment. An important feature of the design of the study was that the new instrument was field tested simultaneously in six countries: Australia, USA, Canada, England, Nigeria and Israel. This paper is based on a sample of 4643 students in 225 individual laboratory classes, together with the teachers of most of these classes. Preliminary analyses were used to shed light on various important research questions including the differences between Actual and Preferred environments, gender differences in perceptions of Actual and Preferred environment, the relationship between the science laboratory environment and attitude towards science laboratory work, differences between school and university laboratory classes, differences between teachers’ and students’ perceptions of the same laboratory classes, and differences between laboratory classes in different science subjects (Physics, Chemistry, Biology).

A large and burgeoning literature has established that mastery goal orientations yield positive cognitive and behavioural educational outcomes. Less research has focused on the psychological antecedents of adopting mastery goals. The present study draws upon prominent psychological theories of ac motivation, specifically the expectancy-value theory of Eccles, Wigfield and colleagues (Wigfield and Eccles 2002), to explore possible antecedents of students’ mastery goals. Based on this theoretical framework, our study focused on children’s perceptions of their competencies in English and maths and how these related to intrinsic value and mastery goals for English and maths. Questionnaires were used to gather data about Year 6 (N=60) participants’ perceived competence, intrinsic value and mastery goal orientation, and correlational analyses established the direction and strength of the relationships between the perceptions. Participants were targeted for follow-up interviews (n=17) according to a matrix of low and high competence perceptions and mastery goals, with students selected from within each of six focal groups. Interview responses were reported according to emergent themes, from which we describe how the constructs under consideration relate to one another and highlight implications for educational practice.  相似文献

Situating Skills   总被引:2,自引:0,他引:2  
The discourse surrounding skills in education and learning has often been dismissed as mere 'skill–talk'. This article seeks to reject this criticism by arguing that much of the criticism of skill–talk rests on an unsatisfactory behaviourist view of skills. Another approach towards considering skills is also considered, an approach deriving from the Aristotelian concept of technē , but this is also rejected. It is suggested that the concept of 'situational understanding' provides the best way of thinking about skills. This approach firmly situates the learning of skills within context: the possibility of all–purpose generic skills is rejected. At the same time, this approach helps to articulate what is needed from the standpoint of agency if skills are to be 'transferred'.  相似文献

This report provides evidence of the influence of professional development and curriculum on upper elementary students' understandings of fractions. Three groups of teachers and their students participated. Two groups implemented a fractions unit that emphasized problem solving and conceptual understanding. The Integrated Mathematics Assessment (IMA) group participated in a program designed to enhance teachers' understandings of fractions, students' thinking, and students' motivation. The Collegial Support (SUPP) group met regularly to discuss strategies for implementing the curriculum. Teachers in the third group (TRAD) valued and used textbooks and received no professional development support. Contrasts of student adjusted posttest scores revealed group differences on two scales. On the conceptual scale, IMA classrooms achieved greater adjusted posttest scores than the other two groups, with no differences between SUPP and TRAD groups. On the computation scale, contrasts revealed no differences between IMA and TRAD, although TRAD achieved greater adjusted scores than SUPP (p < 0.10). Our findings indicate that the benefits of reform curriculum for students may depend upon integrated professional development, one form exemplified by the IMA program. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

ABSTRACT

Since the mid-1980s, the working lives of teachers has become an enduring research topic. Much research has focused on early-career teachers and is often reported from deficit positions, i.e. why they leave the profession. However, career trajectory studies have described a small cohort of veteran teachers who remain positive and committed to teaching. This article reports on the creation and piloting of an instrument designed to test whether this positive cohort can be empirically identified within a wider teaching population. Four constructs (experimentation, challenge, comfort and leadership) drawn from Huberman (1993), and Day and Gu (2007) formed the basis for an online pilot survey completed by 145 teachers. Exploratory and confirmatory factor analysis supported three of the four factors (experimentation, comfort, leadership), with challenge loading strongly with experimentation. Initial findings suggest the potential of the instrument in helping identifying positive veteran teachers within systems, as well as the voracity of the research approach. Examining and articulating how these veteran teachers maintain their positive outlook may prove valuable as many countries confront an ageing teaching workforce, increasing student numbers and difficulties in retaining experienced teachers, meaning those who remain will be expected to sustain their commitment for longer.  相似文献
