Purpose: This paper reflects upon the practice of Argentine rural extensionists working in the extension public system through the process of identifying different rural extensionists' types of mindsets and comparing them with transfer of technology extension approach, dialogical processes of horizontal knowledge exchange, participatory perspectives and innovation system approach.
Design/Methodology/approach: A quali-quantitative investigation was conducted. Surveys containing closed and open questions were sent via email to rural extensionists. This allowed the researcher to identify their beliefs about different issues connected to extension practice. The sample was incidental (n = 219; 143 men, 76 women). Qualitative data was categorized and quantified. Finally, a two-steps cluster analysis was implemented.
Findings: Two types of rural extensionists' mindsets were identified, one of which relates to the transfer of technology approach and other to the dialogical/horizontal model, yet neither of them fitting the ideal of the most important extension institution of the country, which supports an innovation system approach.
Practical implications: Extensionists' practices and institutional ideals do not coincide. Reflexive training processes are required to make beliefs about rural extension explicit in order to build a contextually suitable extension proposal. Originality/Value: Through a quali-quantitative approach to the issue of rural extensionists' mindsets, this paper contributes to a better understanding of Argentine rural extensionists' practices. 相似文献
Students can generate teaching materials for others. However, solid evidence of the learning effect for the student creating the material is needed. This meta-analysis aims to explore current evidence of the learning-by-teaching potential effect on students’ learning of the content they teach. A total of 23 articles were included in the meta-analysis, providing 62 comparisons between an intervention in which students were required to create a teaching material and an alternative condition. Possible moderators were examined as well (i.e., product, educational level, content area, and access to source material). Results show statistically significant differences in favour of creating teaching materials when compared to business-as-usual or alternative interventions, with an overall effect of 0.17. However, the type of product and the access to source material significantly moderate the findings. Audio-visual and visual materials considerably outperform textual materials. Having no access to the source material is better than having full access to it. No publication bias was detected. However, the type of control group moderates the findings: creating teaching materials shows a significant effect when compared to nonbeneficial interventions rather than to other expected beneficial interventions. Nonbeneficial interventions refer to business-as-usual or alternative interventions that are not expected to influence the outcome much, while beneficial interventions are those that are known or expected to have a positive effect. The findings are discussed based on the different views on the underlying learning-by-teaching mechanisms. Limitations as well as implications for practice, policy, and future research are underlined. 相似文献
Many studies investigating inquiry learning in science domains have appeared over the years. Throughout this period, inquiry learning has been regularly criticized by scholars who favor direct instruction over inquiry learning. In this vein, Zhang, Kirschner, Cobern, and Sweller (2022) recently asserted that direct instruction is overall superior to inquiry-based instruction and reproached policy makers for ignoring this fact. In the current article we reply to this assertion and the premises on which it is based. We review the evidence and argue that a more complete and correct interpretation of the literature demonstrates that inquiry-based instruction produces better overall results for acquiring conceptual knowledge than does direct instruction. We show that this conclusion holds for controlled, correlational, and program-based studies. We subsequently argue that inquiry-based and direct instruction each have their specific virtues and disadvantages and that the effectiveness of each approach depends on moderating factors such as the learning goal, the domain involved, and students' prior knowledge and other student characteristics. Furthermore, inquiry-based instruction is most effective when supplemented with guidance that can be personalized based on these moderating factors and can even involve providing direct instruction. Therefore, we posit that a combination of inquiry and direct instruction may often be the best approach to support student learning. We conclude that policy makers rightfully advocate inquiry-based instruction, particularly when students’ investigations are supplemented with direct instruction at appropriate junctures. 相似文献
Student ratings are widely used to assess teaching quality in primary and secondary education. This necessitates a thorough examination their validity and reliability in such contexts. To this end, we present validity evidence for using student ratings of teaching quality based on their factorial structure, comparability across grades and subjects, and relation to achievement. Based on data from the 2019 Trends in Mathematics and Science Study (TIMSS) and its national extensions in Norway (N = 3951 5th graders and N = 4575 9th graders), we could confirm a theoretically assumed three-dimensional factor structure (i.e., classroom management, cognitive activation, and supportive climate). Moreover, classroom management and supportive climate were more comparable across grades and subjects then cognitive activation. Finally, classroom management was associated with achievement across all groups, whereas other dimensions showed mixed results, especially across grades. Overall, the findings indicate that students, especially in Grade 9, can provide a valid assessment of teaching quality. 相似文献
The purpose of this research was to develop and test a model of cross-cultural adaptation which proposes that adaptation to movement across cultures involves three processes: learning new social norms, matching behavior to these norms, and matching one's self-concept to the newly acquired behaviors and social norms. According to this model, adaptation problems arise when the foreigner fails in one or more of these processes so as to create various types of mismatches between the components of norms, behavior, and self-concept. Each type of mismatch was hypothesized to lead to a particular affective response and to be most effectively resolved by unique coping strategies which would restore balance among these three components. Successful adaptation, then, occurs when the foreigner uses the coping strategy which is appropriate to the type of mismatch problem encountered in the acculturation situation.This study tested the hypothesized relationship between mismatch problem, affective response, and coping strategy. Subjects were 40 foreign and 40 Canadian students at a Canadian university. They were presented with scenarios depicting five types of mismatches in hypothetical acculturation situations. Results showed that subjects' interpretations of these agreed with the mismatches proposed by the model. Moreover, their reported affective and coping responses confirmed the majority of the hypothesized relationships. These findings suggest the mismatch model may serve as a good framework for classifying diverse adaptation problems and for predicting the coping strategies which would effectively resolve these. 相似文献
