Superintendents from districts in the Minority Student Achievement Network (MSAN) challenged the Strategic Education Research Partnership (SERP) to identify an approach to narrowing the minority student achievement gap in Algebra 1 without isolating minority students for intervention. SERP partnered with 8 MSAN districts and researchers from 3 universities to design and rigorously test AlgebraByExample, a set of 42 Algebra 1 assignments with interleaved worked examples that target common misconceptions and errors. In a year-long random-assignment study, students who received AlgebraByExample assignments had an average 7 percentage point boost on a posttest containing released items from state assessments, and students in the bottom half of the performance distribution where minority students are disproportionately concentrated had an average 10 percentage point boost on a researcher-designed assessment of conceptual understanding. AlgebraByExample is easily incorporated into any existing curriculum, and naturally serves as a launch point for mathematically rich discussion.  相似文献

Abstract

Purpose: This paper aims to reveal, and contribute to an understanding of, the processes that connect learning and innovation networks in sustainable agriculture to elements of the mainstream agricultural regime. Drawing on the innovations and transition literature, the paper frames the analysis around niche-regime interaction using the notion of niche-regime compatibility.

Design/Methodology/Approach: 17 Learning and Innovation Networks for Sustainable Agriculture (LINSA) engaged in agricultural food production, non-food and rural development were analyzed. In line with the project's transdisciplinary approach data were collected in a series of participatory workshops.

Findings: Five modes of LINSA-regime interaction are distinguished based on compatibility. The level of LINSA-regime compatibility influences the extent of the diffusion of LINSA ideas and practices into the regime. However, interaction processes within these modes reveal multiple and diverse connections between LINSA and regime entities suggesting a more complex relationship exists.

Practical implications: A range of connecting processes and activities (for example, certification, exemption from regulation, facilitation of networking) can bring about effective LINSA-regime interaction and could be externally supported.

Originality/Value: Empirical evidence from 17 case studies provides valuable insights from a number of different contexts across Europe. By directing analysis of interaction at the level of LINSA (niche project), rather than at the macro level, the study offers an original perspective. It suggests that the transition to sustainable agriculture might be understood as a complex of interactive processes leading to a series of adaptive changes, rather than as regime change.  相似文献

Although research suggests that the use of child-initiated vs. teacher-directed instructional practices in early childhood education has implications for learning and development, the precise nature of these effects remains unclear. Using data from the Midwest Child-Parent Center (CPC) Expansion Project, the present study examined the possibility that a blend of child- and teacher-directed practices best promotes school readiness among preschoolers experiencing high levels of sociodemographic risk and explored whether the optimal blend varies based on child characteristics. Sixty-two CPC preschool teachers reported their instructional practices throughout the year, using a newly developed questionnaire—the Classroom Activity Report (CAR). The average reported proportion of child-initiated instruction was examined in relation to students’ end-of-year performance on a routine school readiness assessment (N = 1289). Although there was no main effect of child-initiated instruction on school readiness, there was a significant interaction between instruction and student age. Four-year-olds’ school readiness generally improved as the proportion of child-initiated time increased, while 3-year-olds showed a U-shaped pattern. The present findings add to the evidence that child-initiated instruction might support preschoolers’ school readiness, although they also suggest this relation may not always be linear. They also point to the importance of examining instructional strategies in relation to student characteristics, in order to tailor strategies to the student population. The CAR has potential as a brief, practical measurement tool that can support program monitoring and professional development.

Today's turbulent business and social environment often compels organizations to adopt internal programs that will help them cope with complexity. One organizational sector in which this is particularly true is the health care industry, as managed care programs and competitive forces have changed the way hospitals and clinics operate. This study looks at a specific organizational program designed to cope with these industry changes and considers the impact of the program on the nurses involved. Drawing on theory and research on role development and strategic ambiguity, this case analysis looks at a hospital system in which the nursing role of “care coordinator”; was defined in a strategically ambiguous way. After analyzing interviews with 19 care coordinators, conclusions are drawn regarding affective reactions to strategic role ambiguity, behavioral adaptation to strategic role ambiguity, and the importance of conceptualizing role ambiguity as a systemic process.  相似文献

An experimental 2 (channel) × 2 (gender) × 3 (time) mixed factorial design (N = 159) was applied to test and compare how individual dimensions of intercultural sensitivity might be affected by two channels: a virtual environment (i.e., Second Life®) versus a Web environment. Using a modified version of Chen and Starosta's Intercultural Sensitivity Scale (ISS), the study sought to identify which of the five ISS dimensions played the most influential role in intercultural sensitivity outcomes: interaction enjoyment, interaction engagement, interaction confidence, interaction attentiveness, or respect for cultural differences. Results showed that one's willingness and effort toward understanding an intercultural interaction – interaction attentiveness – played the greatest and most statistically significant role in intercultural sensitivity outcomes, and that this effect was greatest within the virtual environment channel. Gender effects were also found, in which men experienced greater enjoyment but women expressed more attentiveness.  相似文献

Dr Lesley Cullen-Powell and Professor Julie Barlow are both chartered health psychologists and both work at the Interdisciplinary Research Centre in Health at Coventry University where Lesley Cullen-Powell is a research fellow and Julie Barlow is a director. In this article, they assess the benefits of a 'self-discovery programme' for children aged six to seven years attending one mainstream primary school. Staff at the school selected 18 pupils, many of them considered to be at risk of exclusion, to participate in the study. The children were allocated either to an 'intervention' or 'non-intervention' group. The children in the intervention group experienced the self-discovery programme over two terms.
Results suggest that the programme was well received by the children. They became more confident, respectful and calm and they displayed less aggressive behaviours during the self-discovery programme. Lesley Cullen-Powell and Julie Barlow are cautious in the interpretation of their findings, but suggest that the self-discovery programme has the potential to help children to feel more positive about themselves and their peers and to re-engage with learning. The authors argue that a wider implementation of the programme, with a controlled study, is now required to evaluate the self-discovery programme in more depth and detail.  相似文献

Knowledge about paediatric speech and language difficulties, training for and contact with children with such problems and views on service developments were explored using a written questionnaire, completed by 84 Tanzanian health and education professionals. Additionally, two sets of interviews were carried out, one with a subset of questionnaire respondents and another with a group of 14 health/education planners and administrators. Results showed that whilst only 41 % of respondents had received training about speech and language difficulties, 68% considered themselves to be responsible for assisting children with such problems. Levels of knowledge were significantly higher in the special education group, but were not significantly related to training, exposure to speech and language therapists, or professional responsibility. However, knowledge levels were significantly related to daily contact with children with speech and language difficulties. No evidence of research or planning for children with such difficulties was discovered. Views on service provision favoured educational over health‐based provision. Qualitative information on attitudes and beliefs about speech and language difficulties did not contradict previous data on disabilities. The implications for Tanzania and other similar countries are discussed. Improvements to the questionnaire are discussed. More data are needed in order to facilitate appropriate service development.  相似文献
