This paper critically analyses the neo‐liberal discourse informing global education policy and practice. We use postcolonial theory to deconstruct the contexts for global educational partnerships, highlighting how issues of power and representation are central to their development and the learning that takes place within them. Teacher development through North—South study visits is one way of challenging teachers’ worldviews, but these are not always effective. We argue that study visit courses, where learning is facilitated by differently knowledgeable others, have the potential to be more effective, but only if the courses are underpinned by postcolonial theory and informed by socio‐cultural pedagogy. 相似文献
Rote teaching and learning have their place, but not in a music course and an art and design course in which two dozen students at Queensborough Community College enrolled together. Through a shared theme, shared assignments, and a shared commitment to making the content relevant and the process active and engaging, two instructors fashioned a powerful environment for learning. 相似文献
The current study investigates (1) whether academic (e.g. math) self-efficacy and academic self-concept represent two conceptually and empirically distinct psychological constructs when studied within the same domain, (2) the nature of the relationship existing between both self-constructs, (3) their antecedents, and (4) their mediating and predictive qualities for background variables such as gender and prior knowledge and outcome variables such as math performance, math interest, and math anxiety. Results indicate that (1) math self-efficacy and math self-concept do indeed represent conceptually and empirically different constructs, even when studied within the same domain, (2) students' academic self-concept strongly influences their academic self-efficacy beliefs, (3) academic self-concept is a better predictor (and mediator) for affective–motivational variables, while academic self-efficacy is the better predictor (and mediator) for academic achievement. These findings underpin the conceptual and empirical differences between both self-constructs as suggested by Bong and Skaalvik [Bong, M., &; Skaalvik, E.M. (2003). Academic self-concept and self-efficacy: How different are they really?. Educational Psychology Review, 15, 1–40.]. 相似文献
The aim of this study was to examine the effects of muscle-tendon length on joint moment and power during maximal sprint starts. Nine male sprinters performed maximal sprint starts from the blocks that were adjusted either to 40 degrees or 65 degrees to the horizontal. Ground reaction forces were recorded at 833 Hz using a force platform and kinematic data were recorded at 200 Hz with a film camera. Joint moments and powers were analysed using kinematic and kinetic data. Muscle - tendon lengths of the medial gastrocnemius, soleus, vastus medialis, rectus femoris and biceps femoris were calculated from the set position to the end of the first single leg contact. The results indicated that block velocity (the horizontal velocity of centre of mass at the end of the block phase) was greater (P < 0.01) in the 40 degrees than in the 65 degrees block angle condition (3.39 +/- 0.23 vs. 3.30 +/- 0.21 m . s(-1)). Similarly, the initial lengths of the gastrocnemius and soleus of the front leg in the block at the beginning of force production until half way through the block phase were longer (P < 0.001) in the 40 degrees than in the 65 degrees block angle condition. The initial length and the length in the middle of the block phase were also longer in the 40 degrees than in the 65 degrees block angle condition both for both the gastrocnemius (P < 0.01) and soleus (P < 0.01-0.05) of the rear leg. In contrast, the initial lengths of the rectus femoris and vastus medialis of the front leg were longer (P < 0.05) in the 65 degrees than in the 40 degrees block angle condition. All differences gradually disappeared during the later block phase. The peak ankle joint moment (P < 0.01) and power (P < 0.05) during the block phase were greater in the 40 degrees than in the 65 degrees block angle condition for the rear leg. The peak ankle joint moment during the block phase was greater (P < 0.05) in the 40 degrees block angle for the front leg, whereas the peak knee joint moment of the rear leg was greater (P < 0.01) in the 65 degrees block angle condition. The results suggest that the longer initial muscle-tendon lengths of the gastrocnemius and soleus in the block phase at the beginning of force production contribute to the greater peak ankle joint moment and power and consequently the greater block velocity during the sprint start. 相似文献
Adopting a longitudinal approach, this article examines downward occupational mobility (DOM) later in working life and its effects on job satisfaction and perceptions of working conditions of older workers in Europe. The main aim was to test whether the risk that workers will be negatively impacted and marginalized in the labor market due to demotion into lower quality jobs is offset by benefits. Based on an ordinal logistic regression of merged Survey of Health, Ageing and Retirement in Europe and English Longitudinal Study of Ageing datasets, the study found a positive significant impact of DOM on overall job satisfaction. Moreover, DOM was associated with a statistically significant reduction in workload pressure, although it did increase physical work demand. This article adds to the literature on marginalization of workers with indications that the lower income and status associated with DOM at older ages may have offsetting benefits. 相似文献
Abstract The recent introduction of micro‐computers into schools is opening up many new avenues for developmental psychologists interested in studying how children learn. Of particular interest at present are approaches in which children program computers themselves, using languages such as LOGO and PROLOG. This paper describes a study in which a simplified version of LOGO was introduced to a group of six‐year‐olds in a severely deprived area of Edinburgh. The children used a special touch‐sensitive keyboard (Concept Keyboard) to control the movements of a floor‐crawling robot called a Turtle. The sessions with the Turtle were marked by high levels of concentration, collaborative problem‐solving and the use of mathematical language. Pre‐ and post‐tests on the British Ability Scales revealed statistically significant gains on the sub‐scales concerned with number and shape: these gains, however, were found only in the boys.相似文献
In this contribution, a theoretical and empirical framework based on work carried out at the Open universiteit (Ou) for a new approach towards the design, production and delivery of flexible, interactive learning materials for distance education is presented.
In the Research and Development centre of the Ou, a project has concentrated on the innovation of current approaches. This framework can also be considered as an advance organizer to reading the remaining articles from the Open universiteit in this issue of Distance Education.
A key feature of the innovation is that during the design phase, course developers have to define ‘models’ of the materials to be developed: a content model, a support model, a student model and the learning path. From a flexibility point of view especially, the ‘student model’ is of importance since it defines the student variables that will be taken into account when developing/ presenting alternative materials (basic content and/or embedded support). A computer‐based system, the ‘Interactive Learning and Course Development Environment (ILCE)’, was developed to support the work of course development teams and tutors on the one hand, and students on the other hand. The development system supports the work of the developers; the delivery system supports the study process of students. The delivery is realised as an on‐line course, on the World Wide Web.
Students start working with the ILCE‐system by following an intake procedure. They can make choices in relation to student variables that have been defined in the student model (profession, study intentions, context, etc.). Next, they can ‘on the fly’ generate a course. Rom the large repository of learning materials only those materials are selected and compiled that are in line with the student model of this specific student Furthermore, they can choose to study the materials on screen and/or make prints of the materials. Of course, in printing the materials they lose the interactive and dynamic possibilities of the computer learning environment 相似文献
