Marginalized discourses and scientific literacy

The central position of this article is that an important component of scientific literacy is an understanding of the reciprocal impact of science and the general culture on each other. The article focuses on the marginalized discourses that have arisen to oppose the racism, sexism, and classism espoused and advocated by mainstream science since its institutionalization until the first half of the 20th century. The article explores the pedagogical value of studying these oppositional discourses to demonstrate the permeability of the boundaries between science and the general culture. It also discusses how the issues raised by these discourses can be used to enhance the scientific literacy of students. J Res Sci Teach 35: 365–374, 1998.     

The impact of colonial and postcolonial Ghanaian language policies on vernacular use in schools in two northern Ghanaian communities

Many ‘alternative primary education’ programmes operating in the developing parts of the world use children’s first language as the medium of instruction. Programme sponsors often base their vernacular language policy on literature that highlights the cognitive and other benefits that accrue from using children’s first languages as the medium of instruction during their early stages in school. Working within a postcolonial discursive framework the paper examines the attitudes of community members, parents, school authorities and schoolchildren toward the use of the vernacular as a medium of instruction in the Shepherd School Programme, an alternative primary education programme, that has been implemented to provide improved educational access for schoolchildren in seven rural northern Ghanaian agri‐pastoral communities.     

Empowerment or Impairment? Involving Traditional Communities in School Management

Community involvement in education has been viewed as a – by no means uncontroversial – means for enabling local members to deepen their participation in the decision-making relevant to their schools by playing a constructive role in the process. On the basis of a study carried out in Ghana, the present contribution to this discussion examines various matters involved in delegating the management of an Alternative Primary Education program to two traditional communities in the north of that country. It also explores how community members, school authorities, the sponsoring non-governmental organization and members of the local management committee themselves perceive such an approach to school management. Issues raised include whether inexperienced and even illiterate local citizens should be allowed to manage their schools, the conflicts which such management often entails and, finally, in what ways it might be beneficially promoted.     

Fostering educational participation in pastoral communities through non-formal education: the Ghanaian perspective

This paper is an investigation of the impact of the Shepherd School Program, a non-formal basic education program implemented in seven pastoral communities in northern Ghana. The paper argues that non-formal basic education programs can have an important impact on the educational development of a community. However, for this to be possible, the context of such programs must answer to communities’ social, cultural, economic and other immediate needs.     

Whose voices are being heard? Mechanisms for community participation in education in northern Ghana

This article reports on a study of community participation in School for Life, a complementary education programme operating in northern Ghana. The researchers investigated three components of community participation: the nature of the mechanisms used to engage community members as participants in the education process; the actors who engage as participants in education; and the factors that enhance or inhibit an individual’s involvement. They found that this programme uses five approaches that work together to make it a viable mechanism to engage communities, and that community members are engaged at various levels, depending on each person’s previous exposure to education. Moreover, regardless of the level at which members participate, doing so empowers the individual and the community.     

The black–white “achievement gap” as a perennial challenge of urban science education: A sociocultural and historical overview with implications for research and practice*

A perennial challenge for urban education in the United States is finding effective ways to address the academic achievement gap between African American and White students. There is widespread and justified concern about the persistence of this achievement gap. In fact, historical evidence suggests that this achievement gap has existed at various times for groups other than African Americans. What conditions prevailed when this achievement gap existed for these other groups? Conversely, under what conditions did the gap diminish and eventually disappear for these groups? This article explores how sociocultural factors involved in the manifestation and eventual disappearance of the gap for these groups may shed some light on how to address the achievement gap for African American students in urban science classrooms. Our conclusion is that the sociocultural position of groups is crucial to understanding and interpreting the scholastic performance of students from various backgrounds. We argue for a research framework and the exploration of research questions incorporating insights from Ogbu's cultural, ecological theory, as well as goal theory, and identity theory. We present these as theories that essentially focus on student responses to societal disparities. Our ultimate goal is to define the problem more clearly and contribute to the development of research‐based classroom practices that will be effective in reducing and eventually eliminating the achievement gap. We identify the many gaps in society and the schools that need to be addressed in order to find effective solutions to the problem of the achievement gap. Finally, we propose that by understanding the genesis of the gap and developing strategies to harness the students' responses to societal disparities, learning can be maximized and the achievement gap can be significantly reduced, if not eliminated entirely, in urban science classrooms. © 2001 John Wiley & Sons, Inc.

Education collaboration to promote school participation in northern Ghana: A case study of a complementary education program

This study explores the perceived benefits and challenges of the collaboration model of a complementary education program which operates in marginalized communities in northern Ghana. The scope of the paper includes the background, collaboration as a transformative process, research methodology, findings, and discussion. The study revealed that: (a) the collaborative partners’ “shared values” were a major drive of the collaboration; (b) the collaboration model was fluid, contextual, and an unstructured process; (c) the process provided new strategies promoting school participation in northern Ghana; and (d) the collaborative partners’ idiosyncrasies posed a major challenge to the collaboration.     

Investigating the nature of formal reasoning in chemistry: Testing Lawson's multiple hypothesis theory

Lawson (1992) posited the multiple hypothesis theory to explain the essence of scientific reasoning. According to this theory, the essence of scientific reasoning is “the ability to initiate reasoning with more than one antecedent condition.” The present study tests the assumptions of this theory with high school students in general experience areas and in chemistry. The findings are generally in support of the theory's assumptions. This article also contains a theoretical discussion which points out how the theory needs to be extended before it can justifiably “constitute the core of a viable alternative theory of reasoning.” © 1997 John Wiley & Sons, Inc.

A study of changes in middle school teachers' understanding of selected ideas in science as a function of an in-service program focusing on student preconceptions

This article examines the impact of a specially designed in-service model on teacher understanding of selected science concepts. The underlying idea of the model is to get teachers to restructure their own understanding of a selected science topic by having them study the structure and evolution of their students' ideas on the same topic. Concepts on topics from the life, earth, and physical sciences served as the content focus and middle school Grades 4–9 served as the context for this study. The in-service experience constituting the main treatment in the study occurred in three distinct phases. In the initial phase, participating teachers interviewed several of their own students to find out what kinds of preconceptions students had about a particular topic. The teachers used concept mapping strategies learned in the in-service to facilitate the interviews. Next the teachers teamed with other teachers with similar topic interests and a science expert to evaluate and explore the scientific merit of the student conceptual frameworks and to develop instructional units, including a summative assessment during a summer workshop. Finally, the student ideas were further evaluated and explored as the teachers taught the topics in their classrooms during the fall term. Concept maps were used to study changes in teacher understanding across the phases of the in-service in a repeated-measures design. Analysis of the maps showed significant growth in the number of valid propositions expressed by teachers between the initial and final mappings in all topic groups. But in half of the groups, this long-term growth was interrupted by a noticeable decline in the number of valid propositions expressed. In addition, analysis of individual teacher maps showed distinctive patterns of initial invalid conceptions being replaced by new invalid conceptions in later mappings. The combination of net growth of valid propositions and the patterns of evolving invalid conceptions is discussed in constructivist terms.
