Purpose: This paper presents economic and pedagogical motivations for adopting information and communications technology (ICT)-mediated learning networks in agricultural education and extension. It proposes a framework for networked learning in agricultural extension and contributes a theoretical and case-based rationale for adopting the networked learning paradigm.

Design/methodology/approach: A review of the literature highlights the economic and pedagogical need for adopting a networked learning approach. Two examples are described to instantiate the language for learning networks: a small community of farmers in India and large Twitter community of Australian farmers.

Findings: This paper reviews evidence that successful networked learning interventions are already occurring within agricultural extension. It provides a framework for describing these interventions and for helping future designers of learning networks in agricultural extension.

Practical implication: Facilitation of learning networks can serve to achieve efficient agricultural extension that connects farmers across distances for constructivist learning. To realize these benefits, designers of learning networks need to consider set design, social design and epistemic design.

Theoretical implication: This paper contributes a theoretical framework for designing, implementing and analysing learning networks in agriculture. It does this by integrating existing ideas from networked learning and applying them to the agricultural context through examples.

Originality/value: This paper contributes an understanding of the value of networked learning for extension in terms of economic and pedagogical benefits. It provides a language for talking about learning networks that is useful for future researchers and for practitioners.  相似文献

Purpose: The key informants in a village setup were studied to understand the existing social and knowledge systems of farmers, their structure, and relationships between different actors. The purpose is to identify different channels of information and use them as a means to disseminate agricultural technologies and related information to farmers.

Design: We use the network map analysis in a case study approach as a tool to demonstrate the linkages between the key actors and stakeholders in the information network of farmers.

Findings: The government institutions are well networked among themselves but have limited interactions with non-government sources. Farmers in Bihar have strong linkages with few network actors, who are important nodes in the social knowledge network. The study showed heterogeneity and complexity in the network shape and structure across different districts.

Practical Implications: Knowledge networks and social networks are the drivers of information sharing and play a significant role in the diffusion of agricultural technology and related knowledge. Understanding these networks provides a platform for introducing the agricultural technologies and getting connected to a wider group of farming communities.

Theoretical Implications: The study shows that the network is formed by different actors and their role determine the nature and shape of the network. Knowledge of this heterogeneity is important in designing or revamping agricultural information systems.

Originality: Information and knowledge networks are least explored in the agricultural information dissemination process. Some studies have shown the role of actors and social networks, but this study uniquely explores and presents the heterogeneity of these networks.  相似文献

Background: Reading is an interactive and constructive process of making meaning by engaging a variety of materials and sources and by participating in reading communities at school or in daily life.

Aim: The purpose of this study was to explore the factors affecting digital reading literacy among upper-elementary school students.

Method: A 3-stage stratified cluster sampling was implemented that resulted in a sample of 592 upper-elementary students from 29 classes in 7 schools. Self-Regulated Learning Strategies Assessment (S-RLSA), Digital Reading Literacy Assessment (DRLA), and student reports of their parents’ education backgrounds were used to collect data on the outcome and predictor variables. Interpretation of these data involved two highly regarded statistical techniques. First, structural equation modeling was used to explore relationships amongst the constructs. Second, multi-group invariance (MI) analyses were used to assess the influence of parental education and self-regulated learning strategies on students’ digital reading literacy.

Results: Enriching students’ family learning resources and strengthening their self-regulated learning abilities could have very important influences on promoting upper-elementary school students' digital reading literacy -webpage information retrieval, reading and communication abilities.

Conclusions: This study also provides information on how teachers can address student resources to improve digital reading literacy and self-regulated strategies.  相似文献

Purpose: In this article the use of blended learning multimedia materials as an education tool was compared with the traditional approach for skills training.

Design/Methodology/Approach: This study was conducted in Ireland using a pre-test, post-test experimental design. All students were instructed on how to complete two skills using either a traditional or blended methodology. They were subsequently assessed to determine their ability to perform the practical skills.

Findings: The findings stressed the suitability of blended learning not only when it was found that there was no significant difference between method of teaching and skill acquisition but also when it was revealed that student demographics had no major influence on skill acquisition.

Practical Implications: It can be concluded that blended learning can be used effectively for the instruction of a diverse range of practical skills in agricultural college and benefit in the successful knowledge transfer to a growing and diverse student population with more emphasis placed on the students taking charge of their own learning environment.

Originality/Value: The article demonstrates the value of blended learning as a successful medium for practical skill attainment within the agricultural college environment.

Purpose: To examine the factors that support and hinder farmers’ learning and to investigate the impact of an innovative learning program on farmers’ practice change.

Design/methodology/approach: Individual interviews and focus group discussions were held with 24 farmers over 20 months. Observations were made of these farmers as they participated with eight agricultural and social scientists in a range of innovative experiences to learn about chicory and plantain establishment and management. These learning experiences were designed around evidence-informed educational pedagogies. Data sets were analyzed using NVivo to determine common themes of affordances and barriers to learning and actual practice changes.

Findings: The affordances for learning and practice change include belonging to a learning community, enhancing self-efficacy, engaging with scientists, seeing relative advantage, reinforcing and validating learning, supporting system’s integration and developing an identity as learners. Barriers to learning and practice change include issues of: trialability, complexity, compatibility and risk.

Practical implications: The importance of basing new models of extension around evidence-informed pedagogies known through educational research to promote learning and practice change.

Theoretical implications: Sociocultural theory and self-efficacy theories of learning are critical to the success of effective agricultural extension programs.

Originality: To date, little empirical research about the affordances and barriers for pastoral farmers’ learning has been based on contemporary educational research.  相似文献

Background: Microorganisms are very important in day-to-day life, but they are inadequately addressed in the Spanish educational system. It is essential that students are well informed about their characteristics and functions.

Purpose: The study aims to find out primary school students’ perceptions of microorganisms and to analyze whether theoretical or practical teaching interventions produce different levels in student’s learning about this topic.

Sample: The sample consisted of 199 primary students in 2nd (aged 7–8) and 6th (11–12) grades from two public schools in Albacete (Spain).

Design and method: This study uses a pre- and post-intervention questionnaire to evaluate the knowledge of students on the issue of microorganisms. We compare differences by age and two teaching–learning intervention methodologies: theoretical and practical.

Results: Results from the pre-test showed a poor understanding and several misconceptions. Children have a limited and negative view of microorganisms, mainly derived from non-formal learning. Both types of intervention provided an improvement in knowledge, but closed questions did not reveal clear statistically significant differences between methods. Open questions showed how the scientific use of the language and quality of verbalization is much better in the groups that received a practical intervention.

Conclusion: The findings can be a starting point for curriculum planners and for teachers interested in engaging students in science learning.  相似文献

Background: Recently, there is a growing interest in independent learning approaches globally. This is, at least in part, due to an increased demand for so-called ‘21st century skills’ and the potential of independent learning to improve student skills to better prepare them for the future.

Purpose: This paper reports a study that explored the effectiveness of two different independent learning approaches: (i) guided independent learning and (ii) unguided independent learning with independent research, in enabling students in an undergraduate Macromolecules course to acquire knowledge in one chemistry context and apply it successfully in another.

Sample: The study involved 144 chemistry students commencing their first term of undergraduate study at a northern university in England. Students completed pre- and post-intervention tests containing 10 diagnostic questions, of which 4 measured students’ knowledge acquisition in one context and 6 measured their ability to apply it in another.

Design and methods: Diagnostic questions had been identified using a Delphi approach. Paired t-tests and chi-square tests were used to analyse the significance of any change in students’ responses to the diagnostic questions and the number of responses evidencing misconceptions, respectively.

Results: Whilst guided independent learning settings were found to improve students’ knowledge and ability to apply that knowledge in novel situations, unguided independent learning had no statistically significant effect. Unguided independent learning was also linked to a statistically significant increase in the number of student misconceptions in one of the diagnostic questions.

Conclusions: The results of this study show that guidance in independent learning activities is a key necessity for effective learning in higher education. This paper has strong relevance and high significance to tertiary STEM education, especially in the light of increased importance of teaching, such as the Teaching Excellence Framework in the UK, and shifts to more independent learning activities.  相似文献

Background: Children generally adopt the behaviours and attitudes they see in their home environment. Because of this, education provided in the school can be effective, as long as it is supported at home and by extension to the entire environment where the child interacts. Isolating the family from school influences the continuance of the school’s educational impact. In this sense, families do have a significant impact on their child’s attitude about.

Purpose: The objective of this study is to determine how parents view science and technology, the factors that influence their views (gender, age, educational level), and the relationship between these opinions and the students’ science academic achievement.

Sample: The present study was conducted with the parents of 169 students attending randomly chosen primary schools in a city in western Turkey.

Design and methods: The ‘Scale for Determining Views of Parents regarding Science and Technology’ (SFDVPAST) was developed by the researchers and used in the present study. The scale’s reliability was 0.88. Data obtained from SFDVPAST were analysed with SPSS 11.5 using frequency (f), percentage (%), average (X), standard deviation (SD), one-way MANOVA, a univariate ANOVA for each dependent variable as a tracking test, and simple linear regression analysis to determine the relationships.

Results: At the completion of this study, findings indicated that gender does not have an impact on how parents view science and technology, but age and educational level do impact parents’ views on this topic. The science academic achievement of the student correlates with the views of his/her parents on science and technology.

Conclusions: Parents’ views towards science and technology have affected their age and education level, but have not affected their sex. In addition, parents’ positive view towards science and technology has affected their science academic achievement of the students.  相似文献

Background: The sophistication of students’ conceptions of science learning has been found to be positively related to their approaches to and outcomes for science learning. Little research has been conducted to particularly investigate students’ conceptions of science learning by laboratory.

Purpose: The purpose of this research, consisting of two studies, was to explore Taiwanese university science-major students’ conceptions of learning science by laboratory (CLSL).

Sample: In Study I, interview data were gathered from 47 university science-major students. In Study II, 287 university science-major students’ responses to a CLSL survey were collected.

Design and methods: In Study I, the interview data were analyzed using the phenomenographic method. Based on the findings derived from Study I, Study II developed an instrument for assessing students’ CLSL by exploratory factor analysis.

Results: Study I revealed six categories of CLSL, including memorizing, verifying, acquiring manipulative skills, obtaining authentic experience, reviewing prior learning profiles, and achieving in-depth understanding. The factor analysis in Study II revealed that the ‘verifying’ category was eliminated, but found another new category of ‘examining prior knowledge.’

Conclusions: This study finally proposes a framework to describe the variations of CLSL, consisting of three features: cognitive orientation, metacognitive orientation, and epistemic orientation. Possible factors influencing students’ CLSL are also discussed.  相似文献

This study report deals with the transition of the young adult through the pre‐leaving years, early work experience (or the lack of it), and social adjustment. It goes on to examine the potential role of network and regional broadcasting.

Initially, it reflects widespread concern about the academic/vocational balance in secondary education, the realism of careers preparation, the unemployed casualty figures, and the quality of school/home and education/industry exchanges. It notes the lack of communication between the agencies involved in their parallel fieldwork, and with the families facing individual dilemmas in education, work opportunity and adolescent disillusion.

In this context, broadcasting's prime role is access to the individual in the family setting where informed home debate and decision‐making are critical. Although specialised programme output has increased, how much relevant help is provided at regional and local level? How available is the essential follow‐up in referral centres, advisory services, print material, etc.? What about parents, teachers, employers, training supervisors and the like who might share their experience and initiative in local self‐help projects? Can general public awareness be stimulated to community action?

But if regional and local stations are to do more, there are many policy and logistic questions to be answered ‐ in partnership with official and voluntary agencies and within a network/regional plan. Although there may be a consensus that the broadcast media could play a valuable part, the question remains ‐ “From whom will the initiative come towards linkage and partnership?”.  相似文献

Background: This study is the second study of a design-based research, organised around four studies, that aims to improve student learning, teaching skills and teacher training concerning the design-based learning approach called Learning by Design (LBD).

Purpose: LBD uses the context of design challenges to learn, among other things, science. Previous research shows that this approach to subject integration is quite successful but provides little profit on (scientific) concept learning. For this, a lack of (knowledge of) proper teaching strategies is suggested as an important reason. This study explores these strategies and more specific the interaction with concept learning.

Sample: Six Dutch first-year bachelor’s degree science student teachers, between the ages of 16 and 18, and two science teacher trainers (principal investigators included) were involved.

Design and methods: A mixed methods study was used to study LBD’s teaching practice in depth. Based on a theoretical framework of (concept) learning-related teaching strategies video recordings of a guided LBD challenge were analysed to unravel teacher handling in detail. Complemented by questionnaire and interview data and students’ learning outcomes (pre- and post-exam) the effectiveness of teaching strategies was established and shortcomings were distracted.

Results: Students reached medium overall learning gains where the highest gains were strongly task-related. Teacher handling was dominated by providing feedback and stimulating collaboration and only 13% of all teacher interventions concerned direct explication of underlying science. And especially these explicit teaching strategies were highly appreciated by students to learn about science.

Conclusions: In accordance with insights about knowledge transfer, LBD needs to be enriched with explicit teaching strategies, interludes according to poor-related science content important for cohesive understanding and de- and recontextualisation of concepts for deeper understanding.  相似文献

During the late 1960s the United Kingdom was one of many countries which faced a potential educational crisis arising from a growing demand for post‐secondary education linked with inadequate resources for its conventional provision.

“Distance learning” techniques, providing an alternative form of study based on multi‐media methods outside formal educational systems, have emerged in response to this new demand.

Within the sector of higher education the Open University of the United Kingdom is one of the most comprehensive distance learning systems.

Many requests have been made to the University for information on distance education and for advice and assistance in establishing similar ventures elsewhere. In response to these developments the University Senate has created recently a Centre for International Co‐operation and Services (CICS).

We give below information on the main functions of this Centre within the framework of the Open University activities.  相似文献

Kindergarten education in the US has a rich heritage. The roots date back to the influence of Froebel with an emphasis on play and to Susan Blow and her concern for the whole child. Comenius regarded early childhood and kindergarten as an inseparable part of education and society as a whole rather than a separate entity. His belief parallels the contemporary approach to kindergarten, as it is increasingly being viewed on a continuum in the educational process.

Significant societal and educational changes in the US during the last two decades have influenced kindergarten education for five‐year‐olds. The American family structure has been effected by the increased divorce rate, the economy, and the increase in two‐employed parents.

Education changes include a shift to an emphasis on standardised testing at all levels, accountability, and the incorporation of four‐year‐olds in public schools. The result has been a ‘spiraling down’ of academic expectations.

In addition, schools are responding to the needs of demographic shifts in the nature of the population. Increasing numbers of children have multicultural backgrounds and English in their second language.

These societal and educational changes have precipitated the movement to the all day kindergarten. As more and more schools offer an all day experience to kindergarten children, numerous issues surface that challenge the original purpose of kindergarten. Entrance age, screening practices, retention, commercial books and materials are all influencing the nature of the all day kindergarten.

The current focus in the US on developmental appropriate practice places the emphasis on child‐centred programs that utilise hands‐ on learning and attention to the development of the whole child. A strong parent education and involvement component, a rich environment, and a qualified teacher are components of a quality kindergarten program. These issues and trends will be discussed within the context of the historical perspective of kindergarten education. The results of a current and thorough literature review will be shared with participants.  相似文献

This paper discusses the role of mentors in individualized learning at Empire State College, New York State. The discussion implicitly questions roles and procedures in distance education.

This individualized learning programme is defined and illustrated. The components of the role of mentor are likewise defined and illustrated. Then the implications of being a mentor working with individual students are spelt out as they illuminate the relationships of mentors in academia.

The conclusion is offered that the mentor's commitment to his/her students is an exhibition of his/her fundamental commitment to a philosophical stance in education which surmounts primary loyalty to one's academic faculty.

The final whimsical question is whether or not individualized learning and distance education are compatible or conflicting.  相似文献

Background: The development of primary pre-service teachers’ chemistry motivation and attitudes toward chemistry were examined in order to develop their science literacy using case-based learning. Students’ ideas were emphasized, real-life situations were discussed, and students could share their ideas and knowledge with peers; as a result, students were active in the learning process.

Purpose: The purpose of the study was to investigate the effectiveness of using case-based learning instruction to increase pre-service primary teachers’ chemistry motivation and improve their attitudes toward chemistry as a school subject.

Sample: The subjects of this study consisted of 51 (20 female, 31 male) freshman primary pre-service teachers from an urban university in Turkey. The mean age of the primary pre-service teachers was 21.

Design and methods: One group pre-test and post-test design was used. A chemistry motivation questionnaire and chemistry attitude scale were used for data collection. For the data analysis, two-way repeated measures of ANOVA and repeated measures MANOVA were conducted.

Results: The results indicated that the mean of the attitude score after the treatment was significantly greater than the mean of the attitude before the treatment. The results also demonstrated that there is no significant difference between females and males. According to the results of the study, there is no significant difference between primary pre-service teachers’ chemistry motivation. However, some chemistry motivation constructs mean scores are greater after the treatment.

Conclusions: In sum, it could be stated that case-based learning is helpful for the development of students’ chemistry motivation and attitudes toward chemistry.  相似文献

Background: For the past decade, science educators have been exploring the use of Socio-scientific Issues (SSI) as contexts for science teaching and learning, and research indicates that doing so can support significant learning gains. However, research related to how teachers take up the practice of SSI-based instruction is far more limited, due in part to a lack of tools for use in this kind of research.

Purpose: The focus of this research is development and testing of a new classroom observation protocol specifically designed for SSI-based instructional contexts.

Design and methods: Development of this SSI-Observation Protocol (SSI-OP) took place in four distinct phases: review of existing protocols and SSI-based instruction frameworks, writing and revision of protocol items, initial testing of the draft protocol, and soliciting feedback from SSI experts.

Sample: Following the four stages of SSI-OP development, we progressed to a series of field tests. The field tests were conducted with three different samples. The first sample was an experienced (10 + years) high school biology teacher and one of her honors biology classes. The second sample consisted of seven Turkish Pre-service Science Teachers (PST) participating in a science methods course. The third sample included two Thai PST from a field experience course embedded within a teacher education program.

Results: The final version of the protocol addressed five dimensions of SSI-based instructional activities: focus of instruction, teaching moves, role of teacher, role of students, and classroom environment.

Conclusions: The SSI-OP could be used in a variety of ways for research including documentation of current practices, impacts of professional development and/or curricula on teaching practices, and changes in teaching over time. We offer the SSI-OP as a new tool with the potential to contribute to science teacher education and research that may advance the teaching and learning of science through SSI.  相似文献
