This paper evaluates the status of digitization in 30 Nigerian university libraries with a view to identifying the status, progress, prospects and challenges to digitize library materials and form the basis of providing a roadmap to successful execution of digitization projects. The study assessed the status of digitization of past question papers, theses and dissertations in Nigerian university libraries from May to September 2006 through a self-administered questionnaire, site visits and interviews. It was found that, though there are automation services in those universities, there is no digitization of these materials mentioned in the surveyed institutions. The major obstacles militating against digitizing in the university libraries include lack of funds, lack of appropriate facilities, lack of skilled manpower and lack of constant electricity supply. Respondents were anxious to have the services to commence because of their importance in facilitating teaching, learning and research. 相似文献
While the use of Web 2.0 tools and specifically blogs is becoming increasingly popular within higher education (HE) and has been shown to promote learning, relatively little is known about the manner in which such tools may affect how teaching and learning may change as a result of the use of such tools. It is within this context that a connectivist learning model was created and has been further developed within this paper in order to consider the implications of how the use of blogs may change the manner in which teaching and learning occurs. Within this research, a case study of the use of collective student blogs utilized as part of a formally assessed module, undertaken within an HE institution, is utilized to explore the manner in which teaching and learning can be seen to change through a connectivist learning model of blog usage. From this case study, it appears that connectivism does provide a theoretical model for the way in which teaching and learning may change as a result of the use of blogs by learners. However, the experience of staff and students who undertook the project suggests that while a number of elements of the connectivist model can be identified, these are not seen universally among all students. 相似文献
This paper explores the operation and contribution of induction seminars operated as learning communities for new teachers. Mixed methods were used: 378 new teachers and 29 seminar leaders completed questionnaires, 16 new teachers and 14 seminar leaders were interviewed, and 20 seminar meetings were observed. Findings showed that seminar discussions focused primarily on coping with discipline problems, building self-confidence, and developing a professional identity. The main contribution of the seminars was emotional support provided in a non-threatening environment. Findings imply that seminars can be a significant supplement to in-school mentoring for the professional development and adjustment of new teachers. 相似文献
This study explored learning competency based on the Indonesian National Examination focusing especially on chemistry performance and the circumstances of senior high school students and teachers in rural areas of Simeulue Island, Indonesia. The National Examination total score and chemistry score for students in rural areas were consistently lower than students in urban areas during 2008–2010. The majority of rural students were failing to master key chemistry concepts. Their low performance on laboratory-based questions appeared to indicate that the associated practical work was not done as part of the chemistry courses. Some chemistry topics were not taught due to insufficient time, student weaknesses, insufficient textbooks, and other reasons. The issues of low competency of teachers, poverty for the majority of students, low enrollment in schools, and low competition among students in these rural senior high schools appeared to be common problems across rural settings. The local government has recommended providing a consolidated rural high school with qualified chemistry teachers, laboratories, and transportation to address factors negatively influencing student achievement. Furthermore, local rural school officials need to recruit and retain qualified teachers in these isolated areas, provide effective textbooks and instructional resources, and facilitate the professional development of chemistry teachers. 相似文献
This study is about Kenyan pupils' ideas of parks and wildlife. Despite their importance in Kenya, parks and wildlife do not seem to have contributed much in terms of teaching and learning of ecology at school. The findings show a lack of scientific explanation and understanding of issues of wildlife and parks. However, some pupils understand parks and wildlife in terms of their social implications such as socioeconomic benefits, tourism and the resolution of the human-wildlife conflict. The pupils note the potential of parks and wildlife to contribute to the alleviation of poverty and the creation of a more equitable society. They also note the importance of participation in determining park and wildlife ownership in Kenya. 相似文献
Background and Context: Understanding the effects of learner characteristics and perceived learning environment on achievement in academic fields including Computer Science (CS) is of critical importance.
Objective: This study aimed at testing a hypothesized model of achievement in CS in terms of the learner and the learning environment characteristics.
Method: Data were collected using a questionnaire administered to a random sample of 315 eleventh and twelfth-grade advanced CS students (28% girls). Structural equation modelling (SEM) analysis was utilized to test the proposed structural model.
Findings: The hypothesized structural model fits the data reasonably, yet five of the 17 assumed effects were not significant. A modified model with only significant effects fit the data well and accounted for 41% of the variance. Mathematics achievement, self-efficacy and classroom learning environment are the most influential variables on achievement in CS.
Implications: The findings bear important implication for helping students by resolving obstacles that obstruct their learning and achievement. 相似文献
Following two decades of corroboration, modeling theory is presented as a pedagogical theory that promotes mediated experiential
learning of model-laden theory and inquiry in science education. Students develop experiential knowledge about physical realities
through interplay between their own ideas about the physical world and particular patterns in this world. Under teacher mediation,
they represent each pattern with a particular model that they develop through a five-phase learning cycle, following particular
modeling schemata of well-defined dimensions and rules of engagement. Significantly greater student achievement has been increasingly
demonstrated under mediated modeling than under conventional instruction of lecture and demonstration, especially in secondary
school and university physics courses. The improved achievement is reflected in more meaningful understanding of course materials,
better learning styles, higher success rates, lower attrition rates and narrower gaps between students of different backgrounds. 相似文献
