Abstract The present study addressed the impact of individual consultation on teaching improvement as measured by changes in student ratings. Subjects included 91 professors who presented naturally for individual consultation services over a seven‐year period at the teaching centre of a Canadian university. Interventions by the consultant fell into three categories: 1) Feedback‐Consultation, 2) Feedback‐Consultation‐Class Observation, and 3) Feedback‐Consultation‐Class Observation and Student Consultation. End of term student ratings for the course that was the subject of the consultation were compared with student ratings for the same course taught between one and three years prior to the consultation service, and for the same course taught between one to three years following consultation. The results showed that, overall, consultation was effective in improving the quality of the consultees’ teaching, as evidenced by an increase in mean student ratings of instruction. This effect persisted post consultation. Not all intervention groups, however, showed the same pattern of results. Change was evident immediately after the intervention except in the case of brief consultation, although follow‐up data showed improved teaching for the latter group. Control data provided evidence that the change in student ratings post consultation could reasonably be attributed to consultation effects. 相似文献

AbstractIn this article we describe the reading comprehension teaching practices of three Chilean teachers, to contrast them with the proposed guidelines from the Chilean Ministry of Education. To do this, we have analysed what contexts of interaction were created in the classroom and which reading processes were promoted by the questions the students were asked. The results show how the teachers’ practices were closer to the ministerial guidelines when they were asked to create specific contexts of interaction, but deviated from these guidelines when the objective was to promote a reflective and critical understanding of the texts. 相似文献

This work shows the capability of principal component analysis (PCA) to detect molecular, chemical and mineralogical changes in historic painting materials subjected to a thermal ageing test (< 250 °C). To simulate the heat-induced alterations an ageing accelerated process was performed on two sets of samples containing two mineral phases (hydroxyapatite and quartz) and two organic compounds (collagen and albumin). The chosen minerals behaved as internal standards during the tests since they are stable and chemically inert at the tested temperatures. Raman microscopy (RM) was applied to characterise one set of samples made of bone, containing ca. 70% hydroxyapatite and 30% collagen. Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy was used to study the other set of samples made of four different quartz/albumin mixtures with quartz contents of 30%, 50%, 70% and 90% (w/w). The aim was to identify the ideal proportion of internal standard to be validated by ATR-FTIR and PCA, determined to be 70%. PCA analyses detected changes in the molecular structures of the organic components while the internal mineral standard remained stable. Moreover, the internal standard IR/Raman bands were constant during the tests and confirmed that the results of PCA analyses were independent of instrumental and technical factors, as well as sample collecting and handling. This demonstrates the potential benefits of our approach to study historical painting materials, which have suffered any type of heat-induced alteration. 相似文献

This study shows how, in the initial training of mathematics teachers, it is possible to promote processes of abstraction and mathematisation through modelling a real situation with the support of auxiliary material to mediate understanding. By adapting elements of the theoretical and methodological framework called Abstraction in Context (AiC), participants’ discussions while building a mathematical model—in a nested epistemic actions—are analysed. Two specific points are discussed in this paper. The first aims to identify how different types of knowledge emerge when an individual is faced with a modelling task. The second is regarding the use of auxiliary material as a means of metaphorising a situation. It was evidenced how the material favours the construction of a mathematical model through the simplification and idealisation that it brings. The meaning constructed for the model is supported in recognising a decreasing behaviour as a part of a whole. 相似文献

This paper elaborates a typology of universities in which each university is characteristically associated with (i) diverse missions, (ii) different ways of producing knowledge and (iii) contrasting pedagogical configurations. Four university forms are identified, analysed and illustrated, namely the expert university, the non-elite university, the entrepreneurial university and the revolutionary university. It is suggested that the typology and the analysis of university forms offered here provide insight into the current positioning of universities in relation to the wider world and have potential in prompting new forms of university for the twenty-first century. The paper further advances another possible university for the future, namely the complex university. The complex university is part of and respectful of diverse ecosystems. It creates new frameworks to understand the world and, in that way, supports social transformations. 相似文献

Background Argumentation is an important discourse process in science that needs to be taught and learned as part of a repertoire of strategies to support the acquisition of scientific literacy. Research in science education indicates that beliefs or perceptions and the epistemological orientations of teachers influence their approaches to science teaching.
Purpose The paper aims to illustrate primary pre-service teachers’ understanding of argumentation based on a study using quantitative methodology. In particular, it aims to illustrate how these teachers view quality of arguments and teaching strategies related to argumentation in the context of a socio-scientific issue on energy.
Sample 332 pre-service teachers enrolled in a university teacher education programme in Spain were investigated. Many studies on argumentation have been conducted with small sample sizes of teachers. Hence, given the sample size, the study provides findings that are likely to be generalisable.
Design and methods A questionnaire was administered to the participants. The design of the questionnaire was guided by some existing analytical tools which were adapted for primary education purposes in the context of socio-scientific issues. This adaptation is novel in that the questionnaire items can potentially be used as diagnostic questions to assess primary teachers’ understanding of argumentation.
Results The results suggest that pre-service teachers had difficulty in understanding arguments and different pedagogical strategies to promote argumentation in classroom. For example, they did not understand the role and the meaning of warrants in scientific arguments and their understanding of the use of different kind of strategies is limited to debates, open discussions and experiments. The age range of the participants and the length of teaching experience had no impact on the quality of their understanding of argumentation.
Conclusions Pre-service science teacher education will benefit from incorporation of more robust and lengthy sessions on argumentation. For example, sessions could focus on quality as well as structure of arguments in science and more diverse pedagogical strategies to support argumentation in science lessons, such as the use of writing frames and presentations. 相似文献

Although research on teacher alienation and isolation has demonstrated the importance of developing collegial relationships, mentoring, and induction programs, there is limited research examining the ways to support critical educators with combatting their feelings of alienation and isolation as it relates to the larger sociopolitical dynamics they must endure. Within teacher education and teacher in-service development we must engage in research and approaches to learning that acknowledge the possibilities and potential of teachers to lead their development toward becoming critical and culturally relevant practitioners. Using an internal colonial framework where schooling is articulated as an extension of the colonial project, this article explores the reflections of ten educators, from the elementary to high school level, as they worked to create spaces for learning within a teacher-led, community based organization. Drawing from participant observations and interviews with organization members, this article explores the ways participation in a community based organization supported teachers with enduring the social and psychological consequences of the alienation they experienced in their schools. The data explore the ways in which participants worked to develop teaching practices drawing from anti-colonial perspectives and through their process developed a sense of solidarity with other teachers, which is discussed as three subthemes: shared beliefs, community, and commitment. 相似文献

Electrophysiology studies have identified two event‐related potentials that are modulated by predictive processes during language comprehension: the N400 and a frontal positivity. The N400 is smaller when words are presented within highly restrictive sentences, indicating reduced lexical retrieval costs. Violations of strong predictions generate larger frontal positivities, possibly reflecting inhibitory processes. More skilled comprehenders may exhibit enhanced predictive processing, but this possibility has seldom been investigated with event‐related potentials (ERPs). We analyzed the association between predictability ERP modulations and reading comprehension abilities. Twenty‐four undergraduate students were exposed to strongly and weakly constraining sentences, ending with an expected or unexpected final word. Their comprehension skills were assessed with a cloze task. Better comprehenders showed smaller N400s for expected words, and larger posterior positivities for unexpected endings, in strongly constraining contexts. These effects correlated with reading comprehension scores. The results suggest that better comprehenders take more advantage of predictions to reduce retrieval costs, and allocate more resources to postlexical integration processes. 相似文献
