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

This article deals with various ‘supported’ acid catalysts developed as alternatives for the conventional ones in organic
synthesis. They have advantages such as producing less toxic waste and using less energy. 相似文献

In this article, we introduce a model of a pedagogical working life horizon. It encompasses questions posed by individual students concerning their future and incorporates the idea of a working life orientation to the pedagogical possibilities within education. Working life orientation consists of three elements: individual relationship, knowledge and skills and employability. In the model, we aim to outline how an orientation to working life might be included in higher education, providing a broad perspective on the various pedagogical possibilities. There are two key pedagogical elements supporting the implementation of the pedagogical working life horizons model: reflection and an inquiring attitude. Our inquiry is a synthesis of socio-constructionist theories of career guidance, a review of international writing on career guidance and working life skills in higher education, adult learning theories and of our practical experiences as educators and scholars in the fields of guidance and adult education. 相似文献

ABSTRACTThis case study examined how the agency of a fifth-grade pupil appeared across different learning environments in the primary school context. In this study, agency is defined as the initiatives taken by an individual in interactive situations. The research question is: how does a pupil’s agency manifest and vary through taking initiatives across different learning environments within curriculum-based education? The empirical data consist of 50 video episodes including learning activities in a classroom, in a vegetable garden and on a nearby farm. The findings show that the pupil’s agency varied across learning environments, manifesting itself through complementing, supportive, constructive and challenging initiatives. When developing pedagogy that supports learning across formal and informal learning environments, it is essential to enable pupils to take different kinds of initiatives and to exercise their agency in versatile contexts. 相似文献

Learning difficulties have been found to dilute the possibilities that young adults have in their educational careers. However, during the last few decades, education has become increasingly important for employment and overall life satisfaction. In the present study, we were interested in the effects of mathematical and reading difficulties and socioemotional and behavioural problems (measured at age 16) on three educational situations at age 21: delayed graduation from upper secondary education, short educational trajectory and not being engaged in education, employment or training (NEET). The participants (N = 597; 304 females, 293 males) were one age cohort of ninth graders in general education classes, who were followed for five years after completion of compulsory education. This time frame included two different transition phases: first, from comprehensive education to upper secondary education, and second, from upper secondary education to further studies or to working life. Structural equation modelling was used as analysis method. The findings show that mathematical and reading difficulties as well as socioemotional and behavioural problems had significant long-term effects on the participants’ educational careers. New in part was that these learning difficulties seemed to have somewhat divergent emphases on the three investigated life situations: (1) mathematical difficulties, more strongly than reading difficulties, caused the students to attain lower levels of education, (2) mathematical difficulties and socioemotional problems predicted a student ending up in the NEET group and (3) reading difficulties and behavioural problems predicted delayed graduation from upper secondary education. 相似文献

In this study, the relationship between adolescents’ difficulty in mathematics and reading and the influence on academic self-concept and school grades was examined. The participants (N = 585; 299 girls, 286 boys) were one age group of ninth-graders whose mathematics and reading skills were assessed at the end of comprehensive school at age 16 years. Five student profile groups were found using cluster analysis: best achievers, normal achievers (NA), the reading difficulty (RD) group, the mathematical difficulty (MD) group, and the learning difficulty (LD) group. Post-hoc tests revealed that the RD group and the LD group had a higher academic self-concept than the MD group. In school grades history, surprisingly, the NA group and the RD group performed equally well across all school grades. Students in the MD group performed as poorly as the LD group. The results emphasise the prolonged and generalised effects of especially MD on students’ academic careers. 相似文献

Previous studies have showed that early problems with word decoding can lead to poor performance in text reading and comprehension and suggest that poor readers often struggle with reading deficits throughout their school years. Therefore, early detection of those children who are at risk for slow reading development and/or who belong to the lowest reading profiles is essential in order to organize proper support. The present study explores the heterogeneity and prevalence of latent reading profiles among 769 Finnish- and German-reading students during their first and second school years in three countries (Finland, Germany, and Italy) using latent profile analysis. The results identified three latent profiles among Finnish readers, one of which (sentence-level reading) was identified as developing slowly. Among German-reading students, four latent profiles were discovered, two of which were identified as developing slowly. The results of ordinal logistic regression modeling show that rapid automatic naming (RAN) was significantly related to poorer reading profiles among Finnish- and German-reading students, and that the poorer results in letter-sound connection testing among the German-reading group was also significantly related to poorer reading profiles. Although the educational systems have some differences between Germany and German-speaking areas of Italy, no significant country effect was detected. In addition, a child’s age and spoken language did not significantly affect the student’s reading profile. 相似文献
