农业化学课程是来源于农村并且显性于农村的一门课程,它贯穿于整个农村经济的发展过程中。我们应该以“知识改变命运”的理念来树立“不求人人升学,但求人人成材”的新教育观念,实现农业化学课程从“显性”到真正意义上的“显形”,以改变农村“贫”与“愚”的落后现状,采取有效的农业化学知识渗透中学的教学模式,实现教育改革,从而发展社会主义新农村经济。针对西部农村中学课程资源严重不足的现实,提出了开设农业化学课程的三条原则、具体内容以及中学化学教学中渗透农业化学知识的三种具体模式。  相似文献   

Sickness presenteeism of German teachers: prevalence and influencing factors     

Sarah Dudenhöffer  Klaus Schöne  Stephan Letzel  Dirk-Matthias Rose 《Teachers and Teaching》2017,23(2):141-152

The aim of the present study was to investigate teachers’ sickness presenteeism (SP). We examined the prevalence of SP in a sample of teachers as well as work-related and health-related influencing factors of teachers’ SP. We used a cross-sectional study design. Teachers working at different types of schools in Rhineland-Palatinate (Germany) participated in an online survey. We used Pearson’s Chi-squared test (in case of categorical variables) or Mann–Whitney-U-test (in case of continuous variables) to test for differences between SP and sociodemographic/work-related/health-related factors. Factors influencing SP were identified using multivariable logistic regression analyses. Nine hundred and twenty-four teachers working at 42 different schools completed the questionnaire (response proportion: 50.1%). The prevalence of SP in our study was 57.1%. The multivariable logistic regression analyses showed less support by supervisors (aOR: 1.77; 95-CI: 1.21–2.60), inappropriate administration efforts (aOR: 1.56; 95-CI: 1.16–2.11), and inappropriate recognition of performance (aOR: 1.44; 95-CI: 1.04–198) as well as exhaustion/fatigue (aOR: 2.29; 95-CI: 1.71–3.08) as main predictors of teachers’ SP. SP is widespread among teachers. As SP is associated with impairment of psychological and physical health in the long run, it is important to implement measures to reduce SP. A climate of support and cooperation as well as assistance for ill teachers to deal with work missed due to absence might be useful strategies.  相似文献

Shape recognition in infancy: visual integration of sequential information     

S A Rose 《Child development》1988,59(5):1161-1176

To investigate the integration of visual information across space and time, infants watched the contour of a shape being traced out by a moving point source of light and then viewed 2 objects: 1 with the shape they had just seen traced and 1 with a novel shape. In the first study, which varied the number of tracings (velocity about 16.7 cm/sec), 12-month-olds looked longer at the novel object in all conditions, indicating that they recognized the similarity between the alternative object and tracing of like contour. Study 2, which varied velocity (14.7 and 7.4 cm/sec), stimuli, and the number of tracings, provided evidence for the generalizability of these results but indicated that performance suffered at the slower speed. Studies 3 and 4 held velocity constant (14.7 cm/sec) while varying the size of the tracings and age of the infant: 12-month-olds, but not 6-month-olds, recognized figures in instances where it took up to 10 sec to complete a single tracing. Because it took so long to complete many of the tracings, central rather than purely retinal mechanisms appear to be involved in integrating shape in these situations.  相似文献   

Visual Learning and the Brain: Implications for Dyslexia     

Matthew H. Schneps  L. Todd Rose  Kurt W. Fischer 《Mind, Brain, and Education》2007,1(3):128-139

ABSTRACT— The central and peripheral visual fields are structurally segregated in the brain and are differentiated by their anatomical and functional characteristics. While the central field appears well suited for tasks such as visual search, the periphery is optimized for rapid processing over broad regions. People vary in their abilities to make use of information in the center versus the periphery, and we propose that this bias leads to a trade-off between abilities for sequential search versus contemporaneous comparisons. The parameter of periphery-to-center ratio (PCR) describes the degree of peripheral bias, which evidence suggests is high in many people with dyslexia. That is, many dyslexics favor the peripheral visual field over the center, which results in not only search deficits but also (more surprisingly) talents for visual comparison. The PCR framework offers a coherent explanation for these seemingly contradictory observations of both deficit and talent in visual processing. The framework has potential implications for instructional support in visually intensive domains such as science and mathematics.  相似文献   

Keiyo Cattle Raiding, Kechui Mathematics and Science Education: What do They Have in Common?     

Norman Thomson  Jepkorir Rose Chepyator-Thomson 《Interchange》2002,33(1):49-83

In the context of globalization, indigenous educational systems of endangered cultures are faced with extinction. Biologists recognize that biodiversity is dependent upon sustaining and promoting knowledge and values of indigenous cultures. Education researchers have a similar responsibility — to promulgate educational diversity before several thousand years of valuable educational knowledge is extirpated. This paper presents the Keiyo of Kenya who have a rich educational system. Its focus is on an indigenous game, Kechui (using calculations to sharpen your mind), based on cattle raiding, and the Keiyos' use of the game for learning mixed strategy-based probabilistic problem solving. Kechui may also have international potential for teaching probabilistic problem solving in contemporary mathematics and science, especially genetics.  相似文献   

Special and mainstream school collaboration for the promotion of inclusion     

Richard Rose  Caroline Coles 《Journal of Research in Special Educational Needs》2002,2(2)

The Green Paper Excellence for All Children ( DfEE, 1997 ) set out an agenda for the future of special needs provision which was further endorsed by Meeting Special Educational Needs: A Programme for Action ( DfEE, 1998 ). Amongst the recommendations made within these documents was a reappraisal of the role of special schools to support increased opportunities for inclusion. This paper reports on research conducted in one English local education authority (LEA) to examine an approach to develop greater links between a special school and a number of mainstream schools, with the intention of enabling pupils with complex needs to be supported in mainstream classrooms. The research focused upon the procedures which had been developed to support pupils through a period of transition from segregated to mainstream education, and considered those conditions which had been created in order that inclusion might succeed.  相似文献

Support provision for students with Special Educational Needs in Irish Primary Schools     

Richard Rose  Michael Shevlin 《Journal of Research in Special Educational Needs》2020,20(1):51-63

The provision of support for students with special educational needs in schools is seen as a critical factor in the development of inclusive education. The means through which support is provided, continues to be based upon assumptions that individualized learning approaches may remediate learning difficulties. This paper reports findings from a longitudinal study of provision for students with special educational needs conducted in The Republic of Ireland. The authors identify in‐class and withdrawal approaches to support and consider the impact and efficacy of these. It is suggested that the withdrawal of students from class continues to be a dominant model, and that this approach has limitations and may not be conducive to the promotion of inclusive practice. Drawing upon data obtained through interviews with service users (students and parents/carers), and service providers (teachers, paraprofessionals, principals), and those gained from a national survey, the authors present the authentic voices of individuals to illustrate the experiences and opinions of those directly involved in special education in schools.  相似文献   

Using the newspaper to support children's emerging literacy     

June Rose Richie  Janet E. Foster  John M. Johnston 《Early Childhood Education Journal》1991,19(2):28-31

Young children's literacy development involves emerging knowledge, skills, and attitudes about both written and oral language. However, until relatively recent years, children's oral language development has received the lion's share of attention in most early childhood programs. What young children know about written language and their natural ability to learn about writing and reading have been underestimated and misinterpreted and so have received little developmentally appropriate support from early childhood program administrators, teachers, parents, and the public.June Rose Richie is Associate Professor of curriculum and instruction, while Janet E. Foster is Assistant Professor and John M. Johnston is Professor of early childhood education, at Memphis State University, Memphis, TN.  相似文献
