Spillover effects in environmental behaviors,across time and context: a review and research agenda     

Andreas Nilsson  Magnus Bergquist  Wesley P. Schultz 《Environmental Education Research》2017,23(4):573-589

When implementing environmental education and interventions to promote one pro-environmental behavior, it is seldom asked if and how non-target pro-environmental behaviors are affected. The spillover effect proposes that engaging in one behavior affects the probability of engagement or disengaging in a second behavior. Therefore, the positive spillover effect predicts that interventions targeting one specific behavioral have the capacity to promote non-targeted and/or future pro-environmental behaviors. However, the negative spillover effect predicts that engaging in a first pro-environmental behavior will prevent or decrease a second pro-environmental behavior. Since the theoretical and empirical basis for positive and negative spillover effects are not sufficiently understood, the present paper (1) suggests a distinction between behavioral, temporal, and contextual spillovers (2) reviews the existing spillover research literature across a variety of environmental domains, (3) presents potential moderators governing the direction of spillover effects, and finally (4) discuss techniques to promote pro-environmental spillovers.  相似文献   

Role of exteroceptive background context in taste-aversion conditioning and extinction     

Trevor Archer  Per-Olow Sjödén  Lars-Göran Nilsson  Ned Carter 《Learning & behavior》1979,7(1):17-22

In two experiments, saccharin (CS) and lithium chloride (US) were paired in a context consisting of specific visual, auditory, tactual, and olfactory cues. The saccharin aversion was then extinguished in a context free from conditioning-context cues. Later, saccharin preference tests were given in the presence and absence of these cues. The results indicated that the background cues of the conditioning trial controlled the amount of saccharin drunk on extinction trials, and, furthermore, that extinction of the taste aversion was context specific; i.e., groups given extinction trials in a different (from conditioning) context retained their saccharin aversion in the conditioning context only. The results indicate an important role played by the exteroceptive context in taste-aversion conditioning.  相似文献   

The nexus between college choice and persistence   总被引：2，自引：3，他引：2  

Edward P. St. John  Michael B. Paulsen  Johnny B. Starkey 《Research in higher education》1996,37(2):175-220

Initial student commitments have long been considered an influence on persistence, but the reasons why students choose to attend a college have seldom been considered as dimensions of initial commitments that could influence persistence processes and outcomes. This study used NPSAS-87 to examine the influence of finance-related reasons for choosing a college on persistence decisions. The findings include (1) finance-related choices have direct and indirect influences on whether students persist in college; and (2) market-based, monetary measures of financial aid, tuition costs, housing costs, and other living costs have a substantial direct effect on persistence.  相似文献

A new approach to the assessment of children's mathematical competence     

Adolf AF Ekenstam  Margita Nilsson 《Educational Studies in Mathematics》1979,10(1):41-66

The report is a translation of part of a Swedish paper entitled “On Students' Achievement in Mathematics after Finishing Comprehensive School”. The intention of the investigation was to

- diagnose the retention of some basic skills in some topics in algebra and geometry,

- reveal difficult steps in the learning processes in these topics.

Starting with a complicated question, e.g. the equation \(\frac{{3x - 2}}{2} = \frac{x}{3}\) a sequence consisting of 5–15 problems were constructed. Each new problem followed by the preceding one by taking away one or two details. \(\begin{gathered} 3(3x - 2) = 2x \\ {\text{ 9}}x - 6 = 2x \\ {\text{ 7}}x - 6 = 0 \\ {\text{ 7}}x = 6 \\ \end{gathered} \) is an example of a sequence belonging to the equation above. From about 10 complicated problems (“top-items”) and their sequences, in all 130 items, 10 sub-tests were put together in such a way that the pupils who took the test were not aware of the sequences but found no connection between the problems. Many surprising results were found, e.g., that the students scored higher on 14/(x+2)=2 than on 4/x=3, that the difficulty in finding the area of a triangle depended on the position of the triangle and that the problems “Simplify a/a ², a²/a, a/a” were of quite unequal difficulty. A discussion about the students' thinking in patterns and mechanically learning ends the report.  相似文献

Temporal specificity of training: intra-day effects on biochemical responses and Olympic-Weightlifting performances     

Achraf Ammar  Hamdi Chtourou  Khaled Trabelsi  Johnny Padulo  Mouna Turki  Kais El Abed 《Journal of sports sciences》2015,33(4):358-368

The aim of this study was to investigate the performance of an Olympic-Weightlifting session training at three times of the day on the performance related to biochemical responses. Nine weightlifters (21 ± 0.5 years) performed, in randomised order, on three Olympic-Weightlifting training (snatch, clean and jerk) sessions (08:00 a.m., 02:00 p. m., 06:00 p. m.). Blood samples were collected: before, 3 min and 48 h after each training session. Haematological parameters and markers of muscle injury were assessed. Resting oral temperature and rating of perceived exertion (RPE) were also assessed during each session. ANOVA showed that the performance was better (P < 0.001) at 02:00 p. m. with a less RPE (P < 0.01) compared to the morning and the evening sessions while there was higher (P < 0.05) oral temperature at 06:00 p. m. versus 08:00 a.m. and 02:00 p. m. Muscle damage changed immediately (without significant effect after 48 h) after the training sessions with lower values ??in the evening compared to the morning. In conclusion, the afternoon training is more effective than morning or evening sessions for weightlifters. Therefore, coaches and weightlifters should be advised to schedule their training session in the afternoon hour.  相似文献   

Backstage accounting in preschool: analysing dealing with complaints as ‘rehearsing away’ professional knowledge     

Carola Aili  Lars-Erik Nilsson 《Ethnography and Education》2018,13(2):218-234

Citizens of modern societies must trust a broad range of systems and professionals. When distrust arises, professionals are expected to be accountable. This paper draws on conversational material from a preschool team meeting. When a preschool work team prepares to meet a parent who has complained about their recurring neglect to change her child’s nappies ‘in time’, they are found: (1) to carefully review the encounter with the client, (2) in a team-building fashion, to select suitable accounts to offer ‘front stage’ and (3) to internally justify their selection of accounts. Our results indicate that work team members who engaged in backstage rehearsal author the organisation for building trust and, simultaneously ‘rehearse away’ what should remain the organisations’ secrets. Communicating the intent to satisfy was deemed more important than was using evidence from their professional knowledge base.  相似文献   

Focal event,contextualization, and effective communication in the mathematics classroom     

Per Nilsson  Andreas Ryve 《Educational Studies in Mathematics》2010,74(3):241-258

The aim of this article is to develop analytical tools for studying mathematical communication in collaborative activities. The theoretical construct of contextualization is elaborated methodologically in order to study diversity in individual thinking in relation to effective communication. The construct of contextualization highlights issues of diversity in collaborative activities as it emphasizes how students may struggle differently with a learning activity. The interaction of students (12 to 13 years old), playing a specifically designed dice game, is used as an example for illustration. The article shows how accounting for the focal events of the interlocutors, and the contexts in which they contextualize these events, help in organizing our thinking about mathematically effective communication in collaborative activities.  相似文献   

Teaching together and learning together – Primary science student teachers’ and their mentors’ joint teaching and learning in the primary classroom     

Pernilla Nilsson  Jan van Driel 《Teaching and Teacher Education》2010

This paper focuses on what and how primary science student teachers and their mentors learn from planning and reflecting together on each other’s science lessons for pupils aged 7–9. The student teachers had had training in scientific knowledge, but only brief experience of teaching. The mentors were well experienced in the pedagogy of teaching and mentoring, but did not feel confident about their science content knowledge and the teaching of science. Throughout the process of teaching and reflecting together the student teachers and the mentors expressed several specific examples of their joint learning.  相似文献
