The current job market requires scientifically literate human resources. At a time in which scientific reasoning should be part of the higher education curriculum, the general population is pulling away from it. This review aims to identify how students’ and teachers’ attitudes and values influence academic performance in science courses. PICO and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approaches were used to explore four databases and 6488 articles were retrieved. Articles had to be relevant to the research question and published within the last 10 years. Articles without an identifiable author or articles unrelated to the research question were excluded. Following three rounds of quality screening, 10 articles were finally selected for analysis. Study designs and quality varied across the selected articles. Self-efficacy, having mastery goals, perceiving the course as valuable, and having a student identity were consistently associated with good learning outcomes. Cooperation was found to increase task value and autonomy when taking science courses; conversely, a performance approach and a consumer identity were negatively correlated with good learning outcomes. In the past 10 years, there was paucity in research studying the role of teacher attitudes towards science courses on learning outcomes. This article proposes a hypothetical model that describes how attitudes and values may lead to mastery and a good academic performance in undergraduate science courses. With this model, we seek to enhance and strengthen the nature and scope of science education in universities.  相似文献

An assemblage of Buddhist wall paintings and sculptures dating to the twelfth/early thirteenth century are found distributed over the interiors of the temple complex at Sumda Chun, Ladakh. Detailed investigations carried out as part of a conservation project shed light on their antiquity and production technology. The sculptures are constructed with fine mud mortar applied over a wooden armature and affixed to the walls without any support from the ground. In both the sculptures and wall paintings, the paint layer is applied over a thin gypsum ground that functions as a white colourant where unpainted. For the paint layer, azurite, vermilion, and orpiment are the dominant mineral pigments utilized. Minium (red lead) has been used for preparatory drawings and as paint. Highlighting of special areas was achieved using a laminate of tin–lead alloy and gold on relief. Overall the material and techniques employed in the execution of the wall paintings and sculptures are consistent with those reported for other early sites in the region.  相似文献

This paper addresses the perceived consequences of the Chilean national teacher evaluation system. We interviewed 57 school leaders in 30 schools across 10 municipalities about effects and uses of the assessment in their schools. Results show that in the large majority of schools our interviewees observe positive effects such as increased teamwork and internal reflection processes based on the assessment results. Reports about effects at teacher level far outnumber institutional effects, and are mixed. In all schools our interviewees report on teachers’ negative emotions and work overload due to the assessment process, but also about their internalization of the underlying professional standards. The paper analyzes differences among schools and offers suggestions for the development of large-scale standardized teacher evaluation systems.  相似文献

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

This paper presents the results of an analysis of secondary students’ computer use, aimed at understanding how different factors influence the profile of activities carried out by students with computers. The analysis is based on the data from a national study aimed at measuring students’ Information and Communication Technology (ICT) skills for learning. A factor analysis was carried out to categorize students’ activities with computers and several indexes were constructed to define the comparison groups. Finally, a multiple linear regression analysis was performed to explain the frequency of the activities. Results show that students with access to computers at home mainly perform activities categorized as Socializing, Academic, Gaming and Production and that although the absolute frequency of these activities differs across groups, the profiles of computer use are surprisingly similar for groups based on students’ socio-economic group, experience with ICT, and self-confidence in the use of ICT. The only variable that discriminates user profiles is gender. Based on these findings, it can be claimed that Chilean secondary students with access to computers at home tend to show a rather homogenous computer-use profile, once access is equated.  相似文献

The use of formative and shared or co-assessment has been shown to improve the motivation, involvement and learning of university students. The aim of this study is to analyse the effect that implementing these processes has on university students’ perception of their acquisition of transversal competences. The participants in the study were 1021 students from five Spanish universities taking degree courses in primary education or physical education and sport science. They all experienced formative and shared or co-assessment throughout a complete academic year of their courses. For the data collection, a Self-Perception Scale of Transversal Competences was created, which had adequate values of reliability and validity. Using a transversal design (inter-subjects), inferential statistical analysis was undertaken of the differences in means between the perception of a range of transversal competences before and after the course. The results show significant perceived improvements at the end of the course for most of the competences analysed, which indicates, among other thing, the value and importance of this type of assessment for the educational process.  相似文献

ABSTRACT

Purpose: Little is known about effective ways to operationalize agricultural innovation processes. We use the MasAgro program in Mexico (which aims to increase maize and wheat productivity, profitability and sustainability), and the experiences of middle level ‘hub managers’, to understand how innovation processes occur in heterogeneous and changing contexts. Design/methodology/approach: We use a comparative case study analysis involving research tools such as documentary review, key informant interviews, focus group discussions, and reflection workshops with key actors. Findings: Our research shows how a program, that initially had a relatively narrow technology focus, evolved towards an innovation system approach. The adaptive management of such a process was in response to context-specific challenges and opportunities. In the heterogeneous context of Mexico this results in diverse ways of operationalization at the hub level, leading to different collaborating partners and technology portfolios. Practical implications: MasAgro experiences merit analysis in the light of national public efforts to transform agricultural advisory services and accommodate pluralistic agricultural extension approaches in Latin America. Such efforts need long-term coherent macro level visions, frameworks and support, while the serendipitous nature of the process requires meso-level implementers to respond and adapt to and move the innovation process forward. Originality/value: This paper contributes to the debate on how to operationalize large programs by showing that the innovation support arrangements enacted in the field should allow for diversity and have a degree of flexibility to accommodate heterogeneous demands from farmers in different contexts as well as continuous changes in the politico- institutional environment.  相似文献

Perceived social support has been shown to be one of the most important protective factors for emerging adult students during their transition to university. However, the relationships between perceived social support and dimensions of gender and family background, which have been shown to affect adjustment to college life, remain unexplored. The current study analyzes the effect of gender, parents’ education, and family income level on social support perceived by Spanish university students. The sample consisted of 575 women and 280 men, of average age 18.02 years (SD?=?0.52) enrolled in the first year of degree courses at the University of Santiago de Compostela (Spain). Three measures were used to assess various facets of perceived social support, namely perceived acceptance, social provisions, and support availability and satisfaction. Gender differences were identified for several perceived social support dimensions; women reported a wider social network, which should cover more diverse needs of social support. In addition, differences related to mother’s education and family income level emerged for the availability of support and perceived acceptance. The results highlight the different role of gender and family background in several dimensions of perceived social support during the transition to emerging adulthood.  相似文献
