Beyond the Rhetoric of Empowerment: Speak the Language, Live the Experience of the Rural Poor

Growth in rural communities, along with attendant changes in social, economic and environmental conditions, challenges members of these communities to take even more responsibility for their lives than in the past. While there is a need to promote sustainable economic prosperity, it is important that developmental approaches should not compromise the potential of citizens to meet these challenges independently. The present contribution is based on a phenomenological study that explored approaches to community development in Botswana. One of the key findings was that these were dominated by a bureaucratized welfare scheme, as the government gave free food and farming implements to poor people in an approach referred to as atlhama-o-je (‘open-your-mouth-and-eat’). The present contribution reflects on the consequences of using this type of approach, arguing that instead of bringing real hope to the rural poor, it generated counterproductive attitudes. In conclusion, the authors suggest alternative strategies that take account of the life experiences of the rural poor and render them less dependent on government intervention for their well-being.     

Drawing Conclusions from Cross-Lagged Relationships: Re-Considering the Role of the Time-Interval

The cross-lagged panel model (CLPM), a discrete-time (DT) SEM model, is frequently used to gather evidence for (reciprocal) Granger-causal relationships when lacking an experimental design. However, it is well known that CLPMs can lead to different parameter estimates depending on the time-interval of observation. Consequently, this can lead to researchers drawing conflicting conclusions regarding the sign and/or dominance of relationships. Multiple authors have suggested the use of continuous-time models to address this issue.

In this article, we demonstrate the exact circumstances under which such conflicting conclusions occur. Specifically, we show that such conflicts are only avoided in general in the case of bivariate, stable, nonoscillating, first-order systems, when comparing models with uniform time-intervals between observations. In addition, we provide a range of tools, proofs, and guidelines regarding the comparison of discrete- and continuous-time parameter estimates.

Effects of instruction on beginning reading skills in children at risk for reading disability

Children identified in kindergarten as being at risk for reading disability were taught in grades one and two using one of two methods of reading instruction, a structured phonics code-emphasis approach or an approach emphasizing use of context. At the end of first and second grade, children were tested on measures of achievement in word identification, word attack, passage comprehension and spelling. Those in the Code group earned uniformly higher scores on all achievement measures at the end of first and second grades. At the end of first grade, statistically significant differences between groups were found on nonword reading and spelling of phonetically regular words. At the end of second grade, significant differences were found in reading of polysyllabic real words and decoding of monosyllabic and polysyllabic nonsense words. It was concluded that reading instruction does have an important impact on acquisition of early reading skills, and that structured, systematic phonics instruction results in more favorable outcome than does a context emphasis approach.This research was supported by PHS Grant HD21887 to Bowman Gray School of Medicine and by PHS Grant NS19413 to UNC-Greensboro, Subcontract to Bowman Gray School of Medicine.

Assessing the Dimensionality of NAEP Reading Data

The reading data from the 1983–84 National Assessment of Educational Progress survey were scaled using a unidimensional item response theory model. To determine whether the responses to the reading items were consistent with unidimensionality, the full-information factor analysis method developed by Bock and associates (1985) and Rosenbaum's (1984) test of unidimensionality, conditional (local) independence, and monotonicity were applied. Full-information factor analysis involves the assumption of a particular item response function; the number of latent variables required to obtain a reasonable fit to the data is then determined. The Rosenbaum method provides a test of the more general hypothesis that the data can be represented by a model characterized by unidimensionality, conditional independence, and monotonicity. Results of both methods indicated that the reading items could be regarded as measures of a single dimension. Simulation studies were conducted to investigate the impact of balanced incomplete block (BIB) spiraling, used in NAEP to assign items to students, on methods of dimensionality assessment. In general, conclusions about dimensionality were the same for BIB-spiraled data as for complete data.     

Instructional systems design and public schools

A great deal has been written in the last several years about the use or lack of use of instructional systems design (ISD) in public schools. The general discussion has revolved around why ISD has not been accepted by public schools; why instructional design experts have not been hired by public school systems; and primarily what an educational technologist can do to change the situation. The focus of most discussions by educational technologists is: how can schools and teachers alter their practice to benefit from ISD? In this article, we maintain that one reason why ISD has not been adopted in schools is that there may not be a fit between the philosophies, needs, resources, and constraints of schools and the benefits of adopting ISD. We also argue that for ISD to have a significant influence in public schools, it must be accepted by teachers. The general question we ask in this paper is this: are we attempting to redesign schools and classrooms to accommodate our technologies with insufficient attention to the perceived needs of clients and to the consequences of adopting ISD? Our approach to answering this question was to search the literature to uncover perceived inconsistencies between ISD theory and practice on the one hand and teacher needs, wants, and practices on the other.     

Systems learning with a conceptual representation: a quasi-experimental study

In this paper, we share results from a classroom intervention that used a conceptual representation to support reasoning about ecosystems. Engaging students in modeling allows them to make their ideas visible while being malleable and available for discussion, which enables students to make meaning out of systems. Further, the Components-Mechanisms-Phenomena (CMP) conceptual representation was designed to enable students to construct coherent mental models. Following our intervention, students deepened their understanding of ecosystem dynamics when compared to students who engaged in traditional instruction without use of the CMP conceptual representation. We discuss our results in terms of data that helped guide the design of the intervention and we describe a theoretical perspective that can be used to guide future instruction.     

Preschool twin study of the relation between attention-deficit/hyperactivity disorder and prereading skills

Numerous studies have examined the etiology of the association between reading difficulties and attention-deficit hyperactivity disorder (ADHD) in school-age children, but little is known about the relation between prereading skills and ADHD behaviors prior to the beginning of formal reading instruction. A population-based sample of 809 pairs of preschool twins completed an extensive battery of prereading measures, and the parent of each twin completed an ADHD rating scale. Phenotypic analyses revealed small but significant correlations between DSM-IV inattention ratings and six prereading composite measures, whereas hyperactivity–impulsivity symptoms were not independently associated with any of the prereading scores. Multivariate twin analyses indicated that virtually all of the phenotypic correlation between inattention and prereading performance is attributable to common genetic influences, consistent with results obtained in studies of older twins. Although additional research is needed to test alternative causal models in children younger than five years old, these results are most consistent with the hypothesis that reading difficulties and inattention symptoms are attributable to common genetic influences.
