Abstract

Promoting rural development in Africa involves learning to clap with two hands, that is to say, creating effective interaction between local knowledge and development initiatives, on the one hand, and the knowledge and initiatives of formal agricultural research and extension, on the other. Farmer innovators ‐men and women farmers who take their own initiative to change local agriculture ‐ are key allies in rural development, as shown by the experience of the ISWC programme in Africa. Focusing on Ethiopia and Tanzania, the authors describe how formal research and extension services are made aware of farmers’ innovative work and are encouraged to document the results, promote their spread, and support further development efforts by farmer innovators. A modified Participatory Technology Development (PTD) approach is thus emerging, which starts not with problem analysis but rather by linking up with local problem‐solving initiatives. While the learning process on this approach continues, dialogue has been initiated with policy‐makers with a view to incorporating the approach into regular government extension, research and training activities.  相似文献

Previous research has documented a need for the development of a sex education programme in Turkish schools in terms of adolescence readiness and the presence of misconceptions regarding critical aspects of sexual issues. Currently no school‐based sex education is available for Turkish adolescents. This paper presents the development of a contemporary sex education programme for 12‐year‐old to 14‐year‐old adolescents, entitled ‘The Human Development Program for 12–14 Year Old Adolescents’. A five‐step programme development model was used including reviewing internationally recognised sex education programmes for this age group. Sexuality Information and Education Council of United States guidelines were chosen as an educational framework, and Turkish cultural values were integrated into the curriculum. The sex curriculum consists of an eight‐session interactive programme in which parental permission and involvement is required. Five units are presented: human development, relationships, sexual behaviour, sexual health, and society/culture. The programme and a related knowledge assessment tool were reviewed by a group of Turkish professionals and the validity of the educational content was received. The programme was piloted with a group of Turkish adolescents with positive results. Future recommendations include school counsellors implementing this sex educational programme into Turkish schools.  相似文献

Abstract

Purpose: Formal agricultural research has generated vast amount of knowledge and fundamental insights on land management, but their low adoption has been attributed to the use of public extension approach. This research aims to address whether and how full participation of farmers through the concept of Rural Resource Centre (RRC) provides new insights for the development of alternative and farmers-based extension methods.

Design/Methodology/Approach: Using the Concept of RRC, this research assesses the role of farmers in on-farm demonstrations and scaling-up of land management practices, and investigates effective ways to enhance beneficial interactions between researchers, extension workers and farmers in view of improving adoption.

Findings: The findings suggest that farmers can effectively participate in demonstrations and scaling-up of agricultural practices. This participation is enhanced by judicious incentives such as higher crop yields that motivate farmers and influence adoption. The current success of the approach stems from the fact that farmers, extension workers and researchers jointly implement the activities and their different aims were achieved simultaneously: scientific results for researchers, better agricultural practices for extension workers, and economic success and free choice for farmers.

Practical implications: This research concludes that farmers have the capacities to play an innermost role in demonstrations and scaling-up of agricultural practices. However, there is a need to build and strengthen their capacities to facilitate their participation and contribution.

Originality/Value: The article demonstrates the value of the preponderant role of farmers in on-farm demonstrations and scaling-up practices by exhibiting the beneficial interactions between researchers, extension workers and farmers.  相似文献

Inclusion of race and gender in criminal justice education has, to some degree, been prompted as a result of perceived bias by criminal justice system professionals. Utilizing the race and gender experience as a template, interactions between the gay, lesbian, bisexual and transgendered (GLBT) community and the criminal justice system are explored. This study surveyed criminal justice undergraduate degree programs to ascertain course content on gay and lesbian issues. Results indicate that an extremely small number of programs have such a course or alternatively incorporate GLBT issues within existing race and gender courses. Implications for criminal justice education are discussed.  相似文献

The introduction of qualitative modelling techniques into learning environments, and intelligent training systems, requires not just the development of tools and techniques for modelling and simulation but also some guidance on how to use qualitative models in learning environments. This paper describes the rationale behind the design of a simulation based learning environment, the Model Switching PROcess rig Demonstration System (MS‐PRODS). Three qualitative and three quantitative simulations of the behavior of the physical system have been implemented using the ITSIE tools (Scott et al, 1990). The design of the learning environment is presented from the point of view of instruction and how the models are to be used to promote learning, in particular examining the model switching mechanism. This mechanism determines how to select and sequence the presentation of models to the learner during guided explorations of the domain. A knowledge based an alysis of the domain knowledge is combined with principles derived from Cognitive Flexibility Theory (Spiro 6 Jehng, 1990) to produce a generic design for a learning environment based on multiple models. The design and implementation of the learning environment is illustrated and a sample sequence of models presented. Finally, related work such as White & Frederiksen (1990) on model progression is discussed.  相似文献

Although self-assessment is an important genre in both the academy and the workplace, it is often static. The resulting fixed identities are problematic in a creative economy that requires fluidity. Drawing on the work of Carruthers and Goffman, among others, we argue that memory and meditation, encompassing inventory and invention and coupled with rhetorical performance, constitute dynamic self-assessment.  相似文献

Globalization is radically transforming technical communication (TC) both in the workplace and in higher education. This article examines these changes and the ways in which TC programs position themselves amid globalization, in particular the ways in which they use emerging global partnerships to prepare students for global work and citizenship. For this purpose, the authors report on a Council for Programs in Technical and Scientific Communication-supported exploratory study of current partnership initiatives in TC programs. The study indicated a high level of activity, planning, and interest in global partnerships and revealed a range of creative and innovative partnerships that systematically integrate new opportunities for experiential learning, collaborative international research, and civic engagement in a global context into programs and their curricula. Partnerships also emphasize cultural sensitivity, equal partner contribution, and mutual benefit, thus offering alternatives to emerging global trade visions of higher education. The article also identifies key challenges that partnerships face, suggesting implications for programs and the field as a whole to facilitate successful partnerships.  相似文献

This article explores heterogeneity as fundamental to learning. Inspired by Bakhtin's notion of heteroglossia, a design team consisting of an experienced classroom teacher and 2 researchers investigated how a class of 3rd and 4th graders came to understand disciplinary points of view on heat, heat transfer, and the particulate nature of matter. Through a series of planned and unplanned encounters, official versions of the Second Law of Thermodynamics and the particulate view of matter were juxtaposed with varied domains of experience of heat transfer and phase change in water. We analyze the children's discourse to examine how they populated these phenomena with meaning and what they learned in the process. We conclude by describing key principles and a conundrum that emerged from this research.  相似文献

One fact often overlooked in discussing the retention issue is that not everyone who fails to return to school is a dropout. Some persons return after an absence of a semester or more; they can be called stopouts. Some intended to take only a few classes and stop attending when they accomplish their educational goals; they can be called optouts. The only persons who should be labeled dropouts are those who failed to accomplish their educational goal and have no definite plans to accomplish it later.

During the 1990‐91 school year, Del Mar College (DMC) and the Texas A&M Adult and Extension Education program developed and executed a plan to identify, count, and interview nonreturnees at DMC. The purposes of the study were toprovide DMC with baseline data on its nonreturnees and to test the feasibility of gathering interview information by telephone.

Stopouts far outnumbered dropouts and optouts among respondents, with 303 of 399 nonreturnees identifying themselves as such.

In this article, we define relevant terms, outline the data‐gathering process and describe the findings of the present study, and present recommendations regarding data gathering and the focus of retention efforts.  相似文献

This study is an examination of the state of the liberal arts curriculum in community colleges in three geographic regions of the United States. From a constructivist paradigm and using globalization theory as a theoretical framework, this multiple case study examined faculty work life and administrative processes related to curriculum change in merged community and technical colleges. Through an examination of research on globalization, mergers, and trends in the general education and liberal arts curriculum, a gap in the literature emerged in the studies of community college curriculums after merger. This study considers whether the focus on workforce development and decrease in the transfer mission has diminished the liberal arts courses in the college curriculum. Research on liberal arts courses identified them as courses that emphasize higher order thinking and the development of intellectual skills needed to engage in a democratic society. If students are not exposed to these skills, it may have a detrimental effect on a democratic society. Study findings suggested that the English and communication curriculums are narrowing and the mission is more toward workforce skill preparation. Also, the changing demographics of today[#x02019]s community college students, as well as the ongoing budget constraints, create challenges and frustrations for faculty members.  相似文献
