Understanding student-teachers’ decisions to enter and stay in the teaching profession after graduation could help teacher educators to find appropriate procedures to enhance commitment to teaching. This study classified student-teachers based on their levels of commitment to teaching, and described these types based on student-teachers’ motivation to enter the teaching profession and their perceptions of the teaching profession and environmental aspects e.g. school condition and significant others. Thirty-seven undergraduate student-teachers from the Dar es salaam University College of Education in Tanzania were interviewed. Four student-teacher types from our results were identified: (1) committed passionate, (2) committed compromisers, (3) undecided and (4) uncommitted. Implications from the findings include the importance of designing teacher education curriculum in a way that caters for the needs of student-teachers in each type in order to enhance their commitment to teaching.  相似文献

The role of head of department in the pursuit of excellence   总被引:2,自引:0,他引:2  
This article discusses the role and functions of heads of departments as analysed in the literature with particular reference to heads in one Australian university. Data on staff's expectations and perceptions of their head's role are examined.Staff from eight departments of the University of Queensland filled in a questionnaire designed to give feedback to heads. The results show clearly that staff attach great importance to the head's encouragement function: staff wanted their head to encourage good teaching in the department, to stimulate research and publication, and to take account of each staff member's special talents and interests.This was supported by data obtained from over one hundred structured interviews conducted with staff. They were asked, inter alia, what encouragement was given in their department to excellence in teaching and in research; what they would like to see done to encourage teaching and research more and what barriers to excellence existed in the department. Responses indicate that the majority of staff experienced no encouragement for excelling in teaching, whereas most departments and department heads encouraged active participation in research and publication by overt approval, funds, assistance with obtaining outside grants and a variety of other ways. Staff made suggestions on how to overcome the barriers to excellence; these were mostly realistic and practical and, in fact, implemented in those departments where staff felt encouraged in their pursuit of excellence.  相似文献

This paper examines a procedure measuring student competencies in numeracy using school-based assessments, and demonstrates how the procedure informs the school system on quality improvement. The sample consisted of 7648 students, attending three different types of urban schools including government, formal private and low cost private in poor informal settlements in Kenya. The numeracy tool measures six curriculum outcome areas. Each outcome area is defined by 2–11 measured items based on the emphasis given to an area in the curriculum. Within each of the outcome areas, items are also hypothesised to measure categories of the cognitive domain of learning. Using the Rasch, we examine the item difficulties, person location and differential item functioning. The paper provides important implications to provision of evidence to inform teaching in poor urban informal settlements in Kenya and this can also be replicated in other sub-Saharan African countries.

Picture books can influence how children perceive those from backgrounds and cultures different from their own. Studies have been conducted examining how the text of children’s literature portrays multicultural characters or characters with disabilities. However, few have looked specifically at the portrayal of characters through illustrations, despite growing understanding of the importance that illustrations play in text comprehension. Fewer still have analyzed children’s literature for depictions of deaf characters and characteristics of Deaf culture. One recent study examined children’s picture books for portrayals of deaf individuals in the text; however, examining illustrations may provide additional information for both hearing and d/Deaf (For the purpose of this paper, capital “D” Deaf refers to people who are recognized part of the Deaf community; “d” deaf refers to the inability to hear or people unable to hear; d/D includes both populations.) readers about deafness and the Deaf population. In addition, while illustrations are important for all young readers, they may be particularly important for d/Deaf readers who are by nature visual learners. Therefore, the purpose of this study was to conduct a content analysis of illustrations in 20 picture books targeted to ages 4 to 8?years for messages linked to pathological and cultural models of deafness. In addition, results were compared to previous analyses of the text in the picture books. Results indicated that the illustrations do not represent deaf characters from a cultural perspective. Instead, similar to the text, illustrations present deaf characters more frequently as having a pathological condition or disability, that should be fixed through medical interventions in order to fit into a hearing world.  相似文献

The focus of this article is on scale score transformations that can be used to stabilize conditional standard errors of measurement (CSEMs). Three transformations for stabilizing the estimated CSEMs are reviewed, including the traditional arcsine transformation, a recently developed general variance stabilization transformation, and a new method proposed in this article involving cubic transformations. Two examples are provided and the three scale score transformations are compared in terms of how well they stabilize CSEMs estimated from compound binomial and item response theory (IRT) models. Advantages of the cubic transformation are demonstrated with respect to CSEM stabilization and other scaling criteria (e.g., scale score distributions that are more symmetric).  相似文献

In recent years, there has been a renewed interest in the dichotomy of vocational education versus general education. This is more so as political pronouncements in many countries across the globe have taken on knowledge and skills as the key aim of the desire to improve access to education at all levels. Nowhere is this debate more tested, fiercely debated and gained controversy as in Africa. However, given recent developments in which knowledge and skills have become more acceptable terms in economically more developed nations, in which both are seen to go hand in hand, what is happening in Africa where development is highly sought but has proven to be more elusive? This has brought back to the forefront one of the dilemmas which has pre-occupied many African countries for a long time: whether to concentrate investment in general education or in vocational education. In this paper, I reflect on current trends and issues in TVET in Africa.  相似文献

Abstract

Purpose: This study developed a framework for quality assessment of diagnoses and advice given at plant clinics.

Design/methodology/approach: Clinic registers from five plant clinics in Uganda (2006–2010) were used to develop quality assessment protocols for diagnoses and advice given by plant doctors. Assessment of quality of diagnoses was based on five validation criteria applied on the ten most common crops. Quality of advice was assessed for the four major problems considering efficacy and feasibility.

Findings: The quality of diagnoses varied between crops, from 68% completely validated in maize to 1% in tomato. Complete and partially validated diagnoses were 44% of all queries. The remaining 56% were rejected. Several basic weaknesses were found in data recording and symptom recognition. A greater consistency and precision in naming diseases would increase the number of completely validated diagnoses. The majority of recommendations (82%) were assessed ‘partially effective’. ‘Best practice’ was recommended for 10% and ineffective advice was given in 8% of the cases with considerable variation between diseases.

Practical implications: Plant doctors need more training in symptom recognition, pest management and record keeping as well as better technical backstopping to solve unknown problems. Common standards and procedures for clinic data collection and analysis should be established, and roles and responsibilities clearly defined.

Originality/value: This is the first time plant clinic registers have been used to systematically assess quality of plant clinic services. Apart from being a valuable tool for quality assessment of extension, the plant clinic registers constitute a novel source of regular information about pests, diseases and farmer demand that can help improve decision-making of extension service providers, researchers, plant health authorities as well as information and technology providers.  相似文献

Abstract

This article discusses issues of de-professionalization that is fast eroding cataloging and classification practices in academic libraries in Nigeria. It focuses on the factors that led to de-professionalization, its effect on cataloging and classification practices, and the need to re-strategize by retooling and reskilling the cataloging librarian in order to continue to remain relevant in the digital environment.  相似文献

This study investigated differences between two approaches to chained equipercentile (CE) equating (one‐ and bi‐direction CE equating) in nearly equal groups and relatively unequal groups. In one‐direction CE equating, the new form is linked to the anchor in one sample of examinees and the anchor is linked to the reference form in the other sample. In bi‐direction CE equating, the anchor is linked to the new form in one sample of examinees and to the reference form in the other sample. The two approaches were evaluated in comparison to a criterion equating function (i.e., equivalent groups equating) using indexes such as root expected squared difference, bias, standard error of equating, root mean squared error, and number of gaps and bumps. The overall results across the equating situations suggested that the two CE equating approaches produced very similar results, whereas the bi‐direction results were slightly less erratic, smoother (i.e., fewer gaps and bumps), usually closer to the criterion function, and also less variable.  相似文献

There is a sound research base attesting to the importance of parental involvement and to the many potential benefits it can offer for children's education. This study sought to examine differences in parental aspirations (as a mechanism of parental involvement in their children's education) for their children's educational attainment between slum and non-slum residing parents in Kenya. The study used cross-sectional household data for a sample of 4065 parents, collected in 2007 by the African Population and Health Research Centre (APHRC) in Nairobi. A multinomial logistic model was used for the analysis to explore the factors determining parental aspirations. The results indicate the following: (i) that parents who live in the slums have lower aspirations for their children's educational attainment when compared to those who live in non-slum areas; (ii) that parents in the slums have aspirations for higher levels of educational attainment for their children than their own levels of education. We conclude that parents in urban Kenya have a strong belief in the education of their children irrespective of their slum or non-slum residence but aspirations are higher in non-slums than in slums.  相似文献
