Sri Lanka is a nearly industrialized country (NIC country) in transition from a tradition-bound agrarian and cheap labour economy into the era of building a knowledge-based economy. The school system reflects a traditional society, especially in its features of an examination driven system. The question posed for the paper is what meaning the examination driven system has particularly in Sri Lanka and also in general. The method is to apply the conceptual framework of Emile Durkheim to empirical findings and follow his lines of reasoning. The concept mechanical solidarity is central for understanding the assessment system. The education will piecemeal change and become more individualized and learner centred and with new modalities of assessment. It is so if Durheim is right in his claim, that some social facts are caused by other social facts, not just connected to them. 相似文献

AbstractWe examined the progress made by 132 six-year-old French-speaking children in their preliteracy skills during four kinds of interventions. Three of these interventions concerned invented spelling, where the children tried to spell words. In the first condition, they were encouraged to reflect on conventional spellings. In the second condition, they reflected on spellings that were slightly more complex than theirs, while in the third condition, they reflected on increasingly complex spellings that eventually led to the conventional spellings. The fourth condition (control) consisted of phonological training. We assessed the children’s phonological awareness, letter knowledge, spelling, and decoding skills, controlling for vocabulary and nonverbal cognitive ability. Posttest results indicated progress in each condition. The greatest progress was observed in the second condition for decoding, spelling, letter-name knowledge and syllable awareness, and in the control condition for phoneme awareness. Overall, results showed that all kinds of interventions led to very similar levels of progress, but that improvements were greater for interventions that focused on the children’s initial invented spellings - in other words, when they adopted a Vygotskian perspective. 相似文献

This review highlights two areas of particular interest in the study of social learning in fowl. First, the role of social
learning in the development of feeding and foraging behavior in young chicks and older birds is described. The role of the
hen as a demonstrator and possible teacher is considered, and the subsequent social influence of brood mates and other companions
on food avoidance and food preference learning is discussed. Second, the way in which work on domestic fowl has contributed
to an understanding of the importance of directed social learning is examined. The well-characterized hierarchical social
organization of small chicken flocks has been used to design studies which demonstrate that the probability of social transmission
is strongly influenced by social relationships between birds. The practical implications of understanding the role of social
learning in the spread of injurious behaviors in this economically important species are briefly considered. 相似文献

This mixed methods study explores a service-learning experience embedded in a social foundations course in a teacher education program. The authors differentiate learning outcomes for social justice and charity service-learning, and utilize this framework to examine whether the service-learning experience fosters a social justice perspective. The findings demonstrate that while the experience did foster social justice perspectives for some students, the data also reflect evidence of learning outcomes that align with charity service-learning. 相似文献
