If organizations are to develop a capacity to work with mental models then it will be necessary for people to learn new skills and develop new orientations, and for their to be institutional changes that foster such change. ‘Entrenched mental models… thwart changes that could come from systems thinking’ (ibid.: 203). Moving the organization in the right direction entails working to transcend the sorts of internal politics and game playing that dominate traditional organizations. In other words it means fostering openness (Senge 1990: 273-286). It also involves seeking to distribute business responsibly far more widely while retaining coordination and control. Learning organizations are localized organizations (ibid.: 287-301).

it’s the capacity to hold a share picture of the future we seek to create’ (1990: 9). Such a vision has the power to be uplifting – and to encourage experimentation and innovation. Crucially, it is argued, it can also foster a sense of the long-term, something that is fundamental to the ‘fifth discipline’.

When there is a genuine vision (as opposed to the all-to-familiar ‘vision statement’), people excel and learn, not because they are told to, but because they want to. But many leaders have personal visions that never get translated into shared visions that galvanize an organization… What has been lacking is a discipline for translating vision into shared vision – not a ‘cookbook’ but a set of principles and guiding practices. The practice of shared vision involves the skills of unearthing shared ‘pictures of the future’ that foster genuine commitment and enrolment rather than compliance. In mastering this discipline, leaders learn the counter-productiveness of trying to dictate a vision, no matter how heartfelt. (Senge 1990: 9)

By attending to purpose, leaders can cultivate an understanding of what the organization (and its members) are seeking to become. One of the issues here is that leaders often have strengths in one or two of the areas but are unable, for example, to develop systemic understanding. A key to success is being able to conceptualize insights so that they become public knowledge, ‘open to challenge and further improvement’ (ibid.: 356).

In a learning organization, leaders are designers, stewards and teachers. They are responsible for building organizations were people continually expand their capabilities to understand complexity, clarify vision, and improve shared mental models – that is they are responsible for learning…. Learning organizations will remain a ‘good idea’… until people take a stand for building such organizations. Taking this stand is the first leadership act, the start of inspiring (literally ‘to breathe life into’) the vision of the learning organization. (Senge 1990: 340)

In essence, ‘the leaders’ task is designing the learning processes whereby people throughout the organization can deal productively with the critical issues they face, and develop their mastery in the learning disciplines’ (ibid.: 345).

One of the important things to grasp here is that stewardship involves a commitment to, and responsibility for the vision, but it does not mean that the leader owns it. It is not their possession. Leaders are stewards of the vision, their task is to manage it for the benefit of others (hence the subtitle of Block’s book – ‘Choosing service over self-interest’). Leaders learn to see their vision as part of something larger. Purpose stories evolve as they are being told, ‘in fact, they are as a result of being told’ (Senge 1990: 351). Leaders have to learn to listen to other people’s vision and to change their own where necessary. Telling the story in this way allows others to be involved and to help develop a vision that is both individual and shared.

People need to be able to act together. When teams learn together, Peter Senge suggests, not only can there be good results for the organization, members will grow more rapidly than could have occurred otherwise.

It is about fostering learning, for everyone. Such leaders help people throughout the organization develop systemic understandings. Accepting this responsibility is the antidote to one of the most common downfalls of otherwise gifted teachers – losing their commitment to the truth. (Senge 1990: 356)

School administrators and teachers grappling with the often confusing and contradictory premises of these popular initiatives can draw on three useful sources of information: (1) meta-analyses of research studies regarding program effectiveness and instructional practices that support and enhance achievement, (2) studies of the initiatives' effect on English language learners' English language acquisition and academic achievement, and (3) databases that compile language assessments administered to large populations of English language learners over time and across grade levels. Several myths about the instruction of English language learners do not stand up to scrutiny when examined through the lens of this research base.

The "One-Size-Fits-All" Myth

Schools throughout the United States use a variety and range of theoretically sound programs to meet the needs of their specific populations of English language learners, who vary in demographic and linguistic characteristics.

For instance, bilingual programs are appropriate and effective in schools that serve concentrations of students who use a common native language

In many schools, however, English language learners speak a number of different native languages; such schools often use English as the common language of content-area instruction. Therefore, some state agencies and language-minority educators advocate a mix of services and program types in response to each school district's demographic mix—an approach that contradicts the state laws requiring a default model of sheltered English immersion

The "Language of Instruction" Myth

But according to Education Week, cumulative and comparative studies based on National Assessment for Educational Progress (NAEP) scores suggest that statewide mandates limiting bilingual education in California, Arizona, and Massachusetts have produced "less-than-stellar" results (Zehr, 2008, p. 10).

Proponents of the ballot initiatives mandating sheltered English immersion argue that bilingual education is the reason for low levels of English proficiency among immigrant students—especially Latinos, the group served by the vast majority of the bilingual programs.

(Parrish, Pérez, Merickel, & Linquanti, 2006). The study found that students participating in English-only education programs had no statistically significant advantage in terms of academic achievement over those in bilingual education programs that parents chose through the waiver process under the law.

Thus, ballot initiatives have not realized their goal of improving English language learners' academic achievement.

In denying the injunction against the implementation of Proposition 227, the U.S. District Court in Valeria G. v. Wilson (1998) ruled that structured English immersion was based on delivery of English language and content instruction that was "sequential" rather than "simultaneous."

This focus is based on the belief that the "problem" facing these students is essentially a "language problem.

K-12 Program Continuity and Coherence Programs for English language learners must be proven models with a demonstrated track record. Programs must have long-term goals and continuity in the curriculum as students move up through the grade levels. As students' listening, speaking, reading, and writing skills in English grow, the focus of instruction should shift, and instruction should be differentiated according to students' language levels (Mora, 2006). Differentiating the curriculum in this way requires monitoring students' progress toward performance benchmarks in English language proficiency, literacy, and content-area learning (Gottlieb & Nguyen, 2007)

Targeted Professional Development Educators must view the education of language-minority students as a shared responsibility. Teachers must have ample professional preparation in how to use appropriate curricular materials and teaching strategies to promote English language learners' achievement. Both new and experienced teachers need intensive professional development above and beyond the teacher education coursework required by the state credential and certificate programs. For example, teachers should be knowledgeable about second-language acquisition and cross-linguistic transfer so that students learning in their second language can capitalize on the commonalities in literacy with their native language, regardless of whether their instruction is in dual languages.

Local school districts must have the freedom and support to establish sheltered English immersion programs and/or bilingual education programs depending on community values, parental choice, and available resources. Policies must allow flexibility in use of students' native languages—especially for development of literacy skills. In states with anti-bilingual mandates, local jurisdictions should apply liberal and open interpretation of petition and waiver requirements to support parent empowerment and involvement in program selection.
