Beyond genetics in Mental Rotation Test performance: The power of effort attribution     

Angelica Moè  Francesca Pazzaglia 《Learning and individual differences》2010,20(5):464-468

This study compares the effects on Mental Rotation Test (MRT) performance of instructions that stress the importance of (a) personal effort, and (b) genetically driven ability. A total of 120 high-school students were assigned to three groups, and administered two sub-tests of the MRT. Between the first and second sub-tests, the groups received one of the following instructions: effort (“anyone can succeed in this task by putting in effort”), ability (“performance on the test depends on genetic determinants”), and neutral for control (“this is an important test used in many countries”). We predicted that effort but not ability instructions would affect performance. Results confirmed the prediction and showed that, after controlling for baseline performance, the effort group outperformed the ability and control groups, which did not differ from each other. Discussion focuses on the mechanisms implied in believing ability to be genetically determined or experientially driven.  相似文献   

Effect of novel consolidants on mechanical and absorption properties of deteriorated wood by insect attack     

Francesca Lionetto  Mariaenrica Frigione 《Journal of Cultural Heritage》2012,13(2):195-203

The influence of chemical treatments based on novel organic products on the consolidation of deteriorated wood by insect attack was evaluated on two hardwoods and one softwood: fir (Abies alba), beech (Fagus sylvatica) and deciduous oak (Quercus sp.). Degraded and intact specimens of the three wood species were impregnated with two different chemical treatments aimed to verify the potential synergic action of the novel products on wood. Then, the specimens were subjected to bending, compression parallel to the grain, impact, hardness and water absorption tests. Untreated specimens of the same botanical species, both degraded and non-degraded, were examined for comparison purposes. The experimental results showed a different effectiveness of the proposed chemical treatments to improve the mechanical and absorption properties of degraded wood. The most effective treatment was the one assuming the concurrent use of the studied novel consolidants. The species more susceptible of the enhancement in mechanical properties were fir and beech. The observed differentiations were most likely caused by the different structure of the botanical species considered, leading to a consequent different product penetration in the wood structure. The dimensional stability in terms of water repellent and antiswelling efficiency, after a three-month immersion in deionized water, was found to improve in all the treated wood specimens. Overall, experimental results showed that the impact of the chemical treatments was higher on degraded samples than on intact ones.  相似文献

On the Cross-Country Comparability of Indicators of Socioeconomic Resources in PISA     

Artur Pokropek  Francesca Borgonovi  Carina McCormick 《教育实用测度》2017,30(4):243-258

Large-scale international assessments rely on indicators of the resources that students report having in their homes to capture the financial capital of their families. The scaling methodology currently used to develop the Programme for International Student Assessment (PISA) background indices is designed to maximize within-country comparability over time. However, questions remain on the extent to which alternative scaling methodologies can ensure greater cross-country comparability. Establishing indicators of household resources that are comparable both across countries and over time is fundamental to assessing cross-country differences in socioeconomic inequalities in academic achievement. We use multigroup confirmatory factor analysis for categorical variables to examine the measurement equivalence of the household resource factors across the Organisation for Economic Co-Operation and Development countries that participated in the PISA 2000 and 2012 cycles. We construct a series of alternative measures that use students’ reports on the availability of household resources and compare them to the index of home possessions that is generally used in analyses of PISA data. Our findings show that alternative scaling methodologies can be useful in developing cross-country indicators of socioeconomic status.  相似文献   

Eliciting Behavior From Interactive Narratives: Isolating the Role of Agency in Connecting With and Modeling Characters     

Francesca R. Dillman Carpentier  Ryan P. Rogers  Lisa Barnard 《广播与电子媒介杂志》2015,59(1):76-93

A key component differentiating interactive storytelling from non-interactive media is agency, or control over character choices. A series of experiments show that providing agency over a character increased the user-character connection, which then increased engagement in a character-consistent charitable act. Findings were observed in technologically simple online narratives that controlled for navigation/controller differences, graphics, sounds, lengthy play, and avatar customization. Effects emerged even though users did not practice these acts by making their character behave charitably. Findings were robust across happy and unfortunate endings and across first-, second-, and third-person narrative perspectives. Findings suggest promise for developing inexpensive “storygames” to encourage supportive behaviors.  相似文献   

Increasing Knowledge Flows between the Agricultural Research and Advisory System in Italy: Combining Virtual and Non-virtual Interaction in Communities of Practice     

Valentina Cristiana Materia  Francesca Giarè  Laurens Klerkx 《The Journal of Agricultural Education and Extension》2015,21(3):203-218

Purpose: The aim of the paper is to analyse the use of Communities of Practice and Information and Communication Technology (ICT) to enhance knowledge sharing between researchers and advisors. The associated research question is to what extent ICT supported a virtual Community of Practice and has been effective in counteracting fragmentation between research and advisory systems in terms of knowledge sharing between these two pillars of the Italian Agricultural Knowledge System (AKS).

Design/Methodology/approach: The paper uses a mixed methods approach: a questionnaire submitted to the Community of Practice participants on their experiences, observation of interaction between Community of Practice participants and data on the use of the ICT platform.

Findings: The ICT supported Community of Practice approach appears to improve knowledge sharing between researchers and advisors, and also draws in other actors of the broader Agricultural Knowledge and Innovation System in which the AKS is embedded. However, ICT based tools alone are not sufficient and need to be complemented with face-to-face (non-virtual) interactions. A clear theoretical implication of this study is that this is an iterative process in which virtual and non-virtual interaction mutually reinforce each other: ICT interaction spurs real life and face-to-face interaction, and ICT supports follow-up on real life face-to-face interaction.

Practical Implications: Communities of Practice can be a useful tool for knowledge sharing between research and advisory systems, but should have a degree of flexibility in terms of the topics they address and should accommodate new members when appropriate. ICT is supportive, but should be complemented by real life meetings.

Originality/Value: The paper connects recent frameworks of the use of Communities of Practice with literature on ICT in agriculture and adds insights on the contribution of combining virtual and non-virtual interaction in Communities of Practice aimed at knowledge sharing.  相似文献   

Instructional models for the acquisition of English as bridges into school science: effects on the science achievement of U.S. Hispanic English language learners     

Elizabeth H. McEneaney  Francesca López  Martina Nieswandt 《Learning Environments Research》2014,17(3):305-318

Science educators have suggested that, for minority and low-income students, gaps between home and school science cultures necessitate ‘border crossing’ for successful learning in science. Our analysis used National Assessment of Educational Progress 2000 and 2005 data to assess the impact of U.S. state-level policy regarding instructional models for language acquisition for the learning of science. Specifically, we assessed whether policy favouring structured English immersion led to better student outcomes than bilingual education among Hispanic English language learners in 4th and 8th grades in the U.S. We found significantly higher science achievement among 4th grade Hispanic ELLs in states with stronger bilingual emphasis in their policy, suggesting that policy support for bilingual education could provide a better bridge to span the cultural gap between home and school science, at least for younger students.  相似文献   

Students' transition into higher education: The role of self-efficacy,regulation strategies,and academic achievements     

Shanyan Lin  Sofia Mastrokoukou  Claudio Longobardi  Paolo Bozzato  Francesca Giovanna Maria Gastaldi  Martina Berchiatti 《Higher Education Quarterly》2023,77(1):121-137

Transition into higher education (HE) has received increased interest in recent years, since it represents a challenging period for students. The aim of this study was to further understand the associations between self-efficacy, academic achievements, and regulation in first-year university students during their transition into HE. The convenience sample consisted of 374 first-year university students (230 females, 61.5%), aged from 18 to 33 (M = 19.86, SD = 1.51) and recruited from an Italian university. Self-efficacy was assessed using the Motivated Strategies for Learning Questionnaire; regulation strategies were assessed with the Inventory of Learning Patterns of Students; and a self-reported grade point average was taken as an indicator of each student's academic performance. Result shows that students' self-efficacy was positively associated with self-regulation and negatively associated with a lack of regulation. Students with higher self-efficacy and self-regulation strategies had better academic performance. Female students performed better in academic activities and adopted more external regulation strategies. The findings represent an opportunity for university institutions to consider the interventions they provide to first-year students in order to facilitate the successful transition from secondary school; they also provide researchers with further knowledge about the effect of self-efficacy, and regulation strategies on students' adjustment to HE.  相似文献   

Congruency as a nonspecific perceptual property contributing to newborns' face preference     

Cassia VM  Valenza E  Simion F  Leo I 《Child development》2008,79(4):807-820

Past research has shown that top-heaviness is a perceptual property that plays a crucial role in triggering newborns' preference toward faces. The present study examined the contribution of a second configural property, congruency , to newborns' face preference. Experiments 1 and 2 demonstrated that when embedded in nonfacelike stimuli, congruency induces a preference of the same strength as that induced by facedness. Experiments 3 and 4 demonstrated that the attentional biases toward facedness and congruency produce a cumulative effect on newborns' visual preferences according to an additive model. These findings were extended by those of Experiment 5, showing that the additive model holds true when congruency is added to top-heaviness in nonfacelike stimuli displaying more elements in the upper portion.  相似文献   

Educational Justice and Occupational Mobility: The Role of Civic Commitment and of Imagination     

Francesca Gobbo 《The Urban Review》2017,49(3):420-442

In Italy, the exploration of, and debate on, problems of educational rights and justice are not subsumed under the comprehensive rubric of “Urban Education”. They are rather studied from disciplinary realms and approaches such as social education or intercultural education that aim to understand and respond to issues of pressing social, political and educational concerns relative to migration, educational inclusion of immigrants’ and minorities’ children, recognition of cultural diversities as teaching and learning resources, among others. In this article the intercultural perspective is focused on the Italian occupational minority of the fairground and circus people, whose intensely mobile way of life impacts on their children’s school attendance and learning, and on the schools’ capacity to elaborate effective educational paths also able to valorize those people’s cultural diversity. Three relevant “bottom up” projects are here presented that mean to positively answer the mismatch between the mobility of the attractionist students and the schooling curricula, the annual teaching schedule and the attendance requirements.  相似文献
