Best-bet channels for integrated soil fertility management communication and dissemination along the agricultural product value-chain: a comparison of northern Ghana and western Kenya

Purpose: The aim of this paper is to comparatively assess the most suitable channels for dissemination of agricultural innovations along the entire information value chain.

Design/Methodology/Approach: We calculated information scores to measure channel preference from a randomly selected sample of farmers: 285 in Tamale, Ghana and 300 in Kakamega, Kenya. Using t-tests we compared the information score differences of different channels between farmers who adopted Integrated Soil Fertility Management and those who did not.

Findings: The highest information scores were observed for radio along the entire value chain for both locations. However, farmers in Tamale prefered interpersonal channels for processing information. Radio and farmer field days had the highest rankings for production information at both locations. Radio, workshops and interpersonal channels (traders and neighbours/friends/relatives) were best-bet channels for marketing and procesing information.

Practical implication: Extension agents should place more emphasis on channels such as radio, farmer field days, and workshops as they may offer more efficient delivery of information packages at all levels, whilst recognizing the central role of interpersonal channels.

Theoretical implication: The nexus between the uses and gratification, adoption, diffusion of innovations theories and the collaborative communication theory on one hand, and the agricultural product value chain framework on the other, is highlighted. Farmers’ preference for information channels is not predicated on the stage of the value chain.

Originality/Value: In the current context of weak agricultural knowledge and innovation systems in African agriculture, agricultural producers are poorly informed about the current innovations. This study furnishes empirical evidence on the best-bet information channels to be used by extension workers and change agents to disseminate and communicate system innovations.     

Public Internet Usage Points in Schools for the Local Community – Concept, Implementation and Evaluation of a Project in Bremen, Germany

Experts agree that citizens of the information society will need new and additional skills in the future that are connected with the effective and efficient use of digital media technologies. Today, there is unequal access and use of those technologies, which is described as the 'digital divide'. In a unique project, the State of Bremen (Germany) has created Public Internet Usage Points in 25 schools. These 'Web.Punkte' offer access to computers and Internet for the community and support for external users by students. The project is embedded into a larger context of building a regional infrastructure for lifelong learning. Starting with interpretations of lifelong learning, this paper tries to combine those views with concepts to bridge the digital divide, explaining organizational barriers and success factors. Using formative evaluation, the results of the project will be highlighted and arguments for a regional learning network will be drawn.     

What is actually discussed in problem-solving courses for prospective teachers?

The aim of this study is to characterize the discourse of two problem-solving courses for prospective teachers. The data, consisting of audio recordings and field notes, were examined from a dialogical approach combined with the theory of contextualization. I show not only the substantial differences between the two classroom discourses but also elaborate on plausible reasons for the divergency found. The findings then serve as a basis for a discussion of how to develop a problem-solving course within the mathematics teacher program.     

Exploring the Adult Learning Research Field by Analysing Who Cites Whom

In this article we report on findings from a large-scale bibliographic study conducted based on the citation practices within the field of research on adult learning. Our data consist of 151,261 citation links between more than 33,000 different authors whose papers were published in five leading international journals in the field of adult learning during the time period 2006–2014. By analysing the composition of the dominating citation clusters we are able to construct a telescopic view of the research field based on an accumulation of bibliographic citations. The results consist of two parts. First we go through the dominating players active in the field, their position and mutual relationship. Secondly, we derive two main structural oppositions inherent in the citation networks, one connected to the research object (studying education or work) and the second to the level of analysis (cognition or policy). We find that the most dominating tradition within adult learning the last few decades – sociocultural perspectives on learning - occupies a very central position in the space of citations, balancing between these opposing poles. We hope that this analysis will help foster reflexivity concerning our own research practices, and will reveal the relations of dominance currently prevailing within the field of adult learning.     

Problem solving in Swedish mathematics textbooks for upper secondary school

The aim of this study is to analyse how mathematical problem solving is represented in mathematical textbooks for Swedish upper secondary school. The analysis comprises dominating Swedish textbook series, and relates to uncovering (a) the quantity of tasks that are actually mathematical problems, (b) their location in the chapter, (c) their difficulty level, and (d) their context. Based on an analysis of 5,722 tasks from the area of calculus, it is concluded that the textbooks themselves contain very few tasks that can be defined as mathematical problems, and that those that are mathematical problems are found at the end of a chapter at the most difficult level, and are presented in a pure mathematical context. Implications are discussed.     

Can competencies assessed by PISA be considered the fundamental school knowledge 15-year-olds should possess?

The OECD Programme for International Student Assessment (PISA), launched by governments of the Organisation for Economic Co-operation and Development (OECD) in 1997, aims at assessing some of the key competencies that contribute to the success of 15-year-old individuals, on a regular basis and within an internationally accepted framework. PISA seeks to provide a basis for policy dialogue and for collaboration in defining and implementing educational goals, in innovative ways that reflect judgements about the skills that are relevant to adult life. PISA defines competence as the ability to successfully meet complex demands in varied contexts through the mobilisation of psychosocial resources, including knowledge and skills, motivation, attitudes, emotions, and other social and behavioural components. Measuring and comparing competencies across languages and cultures is a difficult challenge and is being pursued by PISA progressively. PISA focused its first three assessments on literacy skills, defined as the capacity of young adults to access, manage, integrate and evaluate information, to think imaginatively, to hypothesise and discover, and to communicate their thoughts and ideas effectively. The reasoning behind shifting the emphasis from assessing whether students can reproduce what they have learned towards whether they can extrapolate from what they have learned and apply their competencies in novel situations, derives from the nature of knowledge and skills required in modern life. For example, the tasks that can be solved through simple memorisation or with pre-set algorithms are those that are also easiest to digitise, automatise and offshore, and will thus be less relevant in a modern knowledge society. Since there is no overarching cross-national and cross-cultural agreement on what fundamental competencies 15-year-olds should possess, an international assessment such as PISA can only capture a selection of competencies. Moreover, since various methodological constraints limit the nature of competencies that are currently amenable to large scale assessment, PISA cannot capture the entirety of competencies that will make young people successful. However, the findings presented in this article suggest that the competencies that PISA does assess are highly predictive for the future success of students. In addition, PISA provides policy makers and practitioners with useful tools to improve quality, equity and efficiency in education, by revealing some common characteristics of students, schools and education systems that do well. In a modern world, comparative assessments are an essential tool for educational improvement and research shows that the existence of standardised assessments and examinations is one of the most powerful predictors for the success of an education system. That is not hard to understand, because without such assessments, all students, schools and education systems look the same, it is impossible for teachers and school administrators to detect institutional and systemic strengths and weaknesses, and to support and intervene where expectations are not met. Without reliable and comparable information on learning outcomes, teachers and governments alike rely on input-based incentives and policies that are all too often mirrored in large quality variation between schools as well as a strong dependency between learning success and the socio-economic context of students and schools. Last but not least, it is important to keep in mind that the absence of the reading, mathematical and scientific competencies measured by PISA does not automatically imply the presence of all those important competencies that have not been measured.     

Die Effektivität schriftlicher und kombiniert auditiv-schriftlicher Wortschatzfördermaßnahmen bei Kindern mit nichtdeutscher Herkunftssprache

Disparities in language competencies of children with and without immigrant background are well-documented through large scale assessments. This study investigates the potential of implicit language promotion, presented in written and combined auditory-written formats. Three experimental groups of 4^th graders in elementary schools have been compared. Intervention group (IV) 1 (n?=?33) read the intervention texts two times in German, IV 2 (n?=?52) read texts in their heritage language Turkish and afterwards in German, and IV 3 (n?=?35) listened to texts in Turkish first and read them in German afterwards. All children learned new vocabulary, but analyses of variance showed that students from IV 2 achieved greater vocabulary gains than IV 3. Results also do not support advantages for the combined auditory-written form including the heritage language. Students’ text comprehension and reading competencies influence their incidental vocabulary acquisition. The results are discussed in the light of practical and research implications.
