Distance Learning for GED® Students in Rural Pennsylvania

Abstract

Although many adult basic education programs offer distance learning (DL) for GED (General Educational Development) and English as a Second Language learners, this topic has received little scholarly attention. This article examines the availability, usage, and effectiveness of DL for rural GED candidates in Pennsylvania; students' demographic and educational characteristics and participation patterns; and the perceived advantages and disadvantages of DL for students and education providers. Data sources included records of 24,143 rural GED students in state-funded programs; GED test takers' demographic survey data; interviews with DL educators and students; and a survey of non-state-funded DL providers. The results show that 4% of rural GED students—primarily young, White, low-income women—participated in DL. Rural DL students were as likely to pass the GED Tests as face-to-face learners. Key advantages and disadvantages of DL for rural GED students are discussed. The study signals great potential and need for expanding DL in rural regions.     

Participant leadership in adult basic education: negotiating academic progress and leadership responsibilities

This article examines the conflicts and challenges that student leaders in adult basic education and literacy programs experience in balancing their leadership responsibilities with academic endeavours. Based upon a case study of an adult basic education student leadership council in New York City, the article shows that leadership activities can both support and impede academic progress. The mediating factors were time requirements for implementation of leadership activities and the perceived priorities of the participants, who used various strategies to manage their academic and leadership responsibilities. Council involvement also supported and changed their academic, vocational and personal aspirations. This study alerts adult educators to the ways in which leadership activities can complicate learners’ academic pursuits, the need both to respect student leaders’ choices and to provide guidance on balancing their multiple responsibilities, and the importance of cultivating literate capabilities through leadership activities.     

Linear stochastic system identification using correlation techniques

The identification of linear, discrete time, scalar output systems which are driven exclusively by white, zero mean, inaccessible noise sequences is discussed. Two principal results are presented. First, two methods (least squares and an autocorrelation technique) for identifying the system characteristic equation coefficients are compared. The least squares approach is shown to be biased except for special cases. In general, the bias cannot be removed. If the state transition matrix is of the phase variable form, bias removal requires a knowledge of the measurement noise variance and all but one of the state driving noise variances. The autocorrelation technique is not biased asymptotically and does not require a knowledge of the noise variances.Secondly, it is shown that the m² elements of the state transition matrix cannot be identified uniquely from the scalar output sequence autocorrelation coefficients if the system order is higher than one. The implication of this uncertainty in the state transition matrix on optimal filtering of the output sequence is briefly discussed.     

State Testing and Inquiry-Based Science: Are They Complementary or Competing Reforms?

The effect of district strategies for improving high-stakes test scores on science teachers practice is explored in case studies of six middle schools in six Massachusetts districts. At each school, science teachers, curriculum coordinators, principals, and superintendents shared their strategies for raising scores, their attitudes towards the test, the changes that they were implementing in their curriculum and pedagogical approaches, and the effects that the test was having on staff and on students. Results from these case studies suggest that districts chose markedly different strategies for raising scores on high stakes tests, and that the approaches taken by districts influenced the nature of pedagogical and curriculum changes in the classroom. District strategies for raising scores that were complementary to the districts prior vision of science reform tended to cause less teacher resentment towards the test than strategies that departed from previously adopted goals. Differing effects on teachers in socio-economically advantaged, middle, and challenged districts are discussed.
