Challenges and Opportunities to Foster School Success

Image for post

Three actualities emerging from recent research indicate that we must focus concentrated attention on low-income children before they enter school: (a) poverty among young children is becoming more intense; (b) poverty coupled with other risk factors, such as chronic neighborhood violence and high stress from urban living, places young children at great risk of negative outcomes; and (c) early intervention with both children and their families can mitigate the effects of poverty and other risk factors and can enhance learning-related outcomes.

 

Much of the intervention research focuses on preschoolers, but a new generation of inquiry focusing on infants and toddlers indicates that intensive child development and early education interventions starting in infancy can result in significantly improved academic and developmental outcomes. Further, evidence from research indicates that the strongest interventions include comprehensive frameworks that focus on both the child and the family, combined with efforts aimed at changing community risk factors. Unfortunately, access to such programs is limited, especially quality programs available to low-income families.

 

Indeed, even within program type there is great variation from one state to another in the specific characteristics of the program supported, eligibility criteria, and access to training. Single strategy approaches (parent education, child care alone, pre-K programs without a family component) are giving way to more complex, interrelated, and comprehensive efforts designed to meet both child-focused needs and family focused needs.

 

The common perception of inner cities is that they are communities without resources, impaired by poverty and neglect. However, urban communities also have a wealth of resources available to them, including academic institutions, cultural centers, business hubs, and health and human services agencies. The real problem is that the resources and services available in urban communities are not linked and often are highly fragmented.

 

Several public and private collaborations have emerged and have been successful in serving families that live in severely disadvantaged circumstances, including the school district’s Family Centers, which integrate and coordinate education, parenting, counseling, and health resources for children, youth, and their families through school-linked services.

 

The following are critical aspects of establishing and maintaining successful partnerships:

 

-        Funding. Lack of funding is the most frequently blamed barrier to any community development program and is often used as an excuse to avoid change and sustain the status quo. Proper planning and better budget oversight can often overcome this barrier, however, and collaboration between agencies that serve the same purpose and people can further save substantial administrative and operations costs. Although the start-up costs for integrating and coordinating services between both public and private entities can be high, these costs do not compare to the long-term savings from streamlined programs that were once duplicated across agencies.

 

-        Data Integration. Modern technology via computers makes it possible to share, accumulate, and integrate data efficiently, which in turn enables agencies to work with clients more effectively. Again, the start-up costs do not compare to the long-term savings due to this type of investment.

 

-        Turf/Interest. Each collaborative member must have a clear understanding of his/her role, as well as the expectations of him/her in the partnership. Further, mutual trust and commitment must exist between partners.

 

-        Regulation. Bureaucratic legislation has often killed excellent visions. Policies must accommodate the needs of the local communities and may be worked with or created anew. Consolidating social, human, and health government functions, for example, may allow the new service agency to adhere to only one set of regulations, while using public funds to create comprehensive service coordination.

 

-        Leadership. Passionate and personal application of top leadership to the project’s priorities is critical to the success of these endeavors. Leaders must also be able to share their visions with other key stakeholders in the community and establish consensus among all the players.

 

Given the growing population of urban children under six in the United States who live in families at or below the poverty line and the movement toward comprehensive strategies in order to address their pressing needs, there are four special design and implementation issues for initiatives involving young inner-city children and families.

 

-        First, program strategies must be responsive to the harsh realities of living in poverty at the same time that they are consistent with principles of adult and child learning and development. Strategies need to be strength- based, as opposed to being based in a philosophy of deficit, while acknowledging the very difficult problems facing families which make daily survival an issue.

 

-        The second imperative that also grows out of the realities of inner-city life is the need to focus not only on children and families, but also on neighborhood issues. Linking with or creating forums for mobilizing action, such as the long-standing Head Start approach to family involvement, produces opportunities for families to address neighborhood and community-based issues. Strategies that build the leadership capacity of family members involved with the program, through participation in all aspects of program activities (including involvement in research projects, governance, etc.), also ensures a broadened focus that includes neighborhood issues.

 

-        A third imperative for inner-city initiatives is to deliberately create strategies to return income to the community, whether through individual program job generation, links with larger community development mechanisms, or other approaches. Empowerment Zones and Enterprise Communities seem particularly useful in developing some of these strategies because community reinvestment and development is so central to their mission.

 

-        A fourth imperative is to focus careful attention on building a system of supports and services for young children and families, not just a series of programs and program-by-program case managers. This requires building a broad community network, including, for example, community leaders, families, Head Start teachers, informal care providers, well-baby clinics personnel, managed care providers, and court personnel. Such community networks should address more technical service integration issues and serve as a link with larger community forums for addressing economic issues and monitoring the impacts of devolution and welfare changes at the most local, neighborhood level. These imperatives can direct current opportunities to craft "street smart" interventions for young children and their families.

How Compatible Is Urban School Reform With The Neighborhood Revitalization? - EbooksCheaper.com

How compatible is urban school reform with the neighborhood revitalization thrust, and how can revitalization efforts in urban communities support the work of the public school? Three perspectives frame the movement toward coordinated children’s services: a new sense of "ecology" that school, family, and community are vitally interdependent; a recognition of the need to build the "social capital" of families and communities; and a call to end the extensive fragmentation in service delivery. The community revitalization approach focuses on family self-sufficiency and independence through employment, a renewed encouragement of private investment in urban communities, and a locally or grassroots-driven strategy of action.

 

Outreach to children and families is by no means incompatible with notions of community development through enterprise. Nevertheless, there are basic ingredients of the approaches that differ. The fundamental strength of coordinated services approaches is that they directly provide for the basic needs of low-income families. However, direct service programs also bear a history of "top-down" execution and professional-centeredness, rather than a focus on community needs and leadership. This history has meant that the call for parental involvement, long recognized as essential to children’s successful learning, has not translated into families being in comprehensive and equal partnership with schools.

 

The strengths of urban renewal initiatives include incentives toward self-reliance, labor, and local development, and a focus on the broad-based issue of economics. Critics of market-driven concepts point out, however, that it is problematic to ask those with the least capital and fewest institutional resources to revitalize their own communities, and that market forces typically have not successfully gathered "have’s" and "have-not’s" together to address the needs of the community.

 

Alone, neither coordinated services nor plans for economic revitalization will significantly improve the learning and healthy development of children and youth in the inner cities. The various strengths and weaknesses of the two approaches should lead policymakers toward neighborhood revitalization approaches which emphasize both professionalized delivery of services to families side-by-side with economic development. The following are suggestions toward merging the strengths of both approaches:

 

- Services to families and children must develop with the full involvement of parents and the community. There must be continued movement toward empowered, co-equal participation of families with professionals in governance and development of schools and the neighborhood. At the same time, the schools and children’s learning must remain central issues and must not be sidelined as expected by-products of employed families and improved economic conditions.

 

- The local school should be recognized as a tangible part of the "basic industry" of the city, with economic and community development responsibilities that go well beyond mere service delivery. It may now behoove the public school to go beyond its traditions of child learning and development, toward a more broadly-conceived role as an active player in the much larger, full-scale development of its community. More than a "service" outreach center, the local school could become a cooperating "investor," maintaining its emphasis on the 3R’s while working extensively with community development agencies and other centers for the family service, such as neighborhood businesses, religious institutions, and civic and governmental agencies. The school’s role as an employer and purchaser of goods/services must be reevaluated as well. Every school contributes to its community through, for example, the provision of lunches, health examinations, and school-age day care. Considering the school’s own accumulation of professionally credentialed "social capital," there tends to be only a minimal understanding among educators that they too are part of a community-based enterprise.

 

- Powerful neighborhood revitalization strategies proceed from the recognition of the interconnections between economic and social, individual and collective, and adult and child well-being. Market solutions assume that people will respond to incentives and utilize opportunities. However, among populations that have long been excluded from the established economy, such assumptions may not be warranted, and the development strand of reform must take these factors into account. Conversely, initiatives for full-service schools must remain aware of the incentive structures—i.e., children are unlikely to remain in school when they doubt its efficacy to help them, seeing that few around them are able to obtain regular work—which vitally affect the schools’ own success.

 

What do these ideas mean for school reform? Schools might tackle issues such as employment options and training, a neighborhood’s attractiveness to investment capital, and adult education, as well as partner with both family "welfare" forces and economic institutions including banks, retail businesses, and insurers. Public schools could be transformed into "enterprise schools," joining with an array of other neighborhood and city institutions in the development and regeneration of the school’s total local ecology and the city itself.
